Syncing provisional tax to cashflow
As a self-employed painter and decorator, Bart Taylor knows full well how business owners can get themselves into strife if they don’t plan for their tax obligations.
He speaks from his own personal experience.
That’s why Bart is happy to talk about how TMNZ enables him as a self-employed tradesperson to take the stress out of having to pay provisional tax on dates dictated by Inland Revenue (IR).
TMNZ offers Bart the flexibility to make the payments when it suits his cashflow.
As someone who doesn’t always get paid every week, that’s important because it offers his business some breathing space while he waits for the money he’s earned from completed jobs to land in his bank account and ensures that other important invoices can be paid in the meantime.
A bit about Bart
Bart owns and operates his own business in Christchurch.
He’s a one-man band and that’s the way he likes it. Plus, most of his work means he does not require a crew, although he will occasionally use contractors when required or on larger jobs.
Bart has been his own boss since 2013, when, at the age of 24, he decided to make a go of this painting lark on his own. The market in the Garden City was awash with painting gigs during the rebuild and becoming self-employed seemed like a low-risk move.
Fast-forward nearly eight years and his gamble has paid off. He is enjoying the benefits that come with self-employment and, as a husband and father in a young family, the better work-life balance he has achieved.
Tough tax lessons
Yet that’s not to say that everything has been a bed of roses during that time.
“Becoming self-employed has been a bit of a rollercoaster. Lots of learnings, lots of difficult times, hard times,” says Bart.
“First and foremost, I’m a tradesman, so I am a worker. The back office, the organisation, the financial side of things is not my strong point. With the tax side of self-employment, I managed it very poorly for years because I was so young.”
Like other business owners, Bart wasn’t as prepared as he should have been and was “stung” in his second year of trading. That was when two years’ worth of tax was due. Ouch.
He admits having to pay provisional tax was “rough for a little while”.
“In the trade industry, you don’t always get paid every week and you need cashflow to run your business,” explains Bart.
“My accountant saw there was a risk of if we paid that tax bill in full, that I might fall short in other areas and he wanted to make sure that my relationship with my trade suppliers stay good and that the invoices I need to pay get paid on time, not just the IR ones.
“He recommended Tax Management NZ and that freed up cashflow.”
Breathing space from IR to manage cashflow
That’s because TMNZ gives Bart the flexibility to pay his provisional tax when it suits his business, without the consequences of steep IR interest and late payment penalties.
It operates with the blessing of the taxman, too.
TMNZ makes a date-stamped payment to IR on Bart’s behalf on the date his provisional tax is due. Bart pays TMNZ at a time when it suits his cashflow.
TMNZ transfers the date-stamped payment to Bart’s IR account and IR treats it as if Bart himself has paid on time. This eliminates any IR interest and late payment penalties showing on his account.
“Sometimes the option of TMNZ, to be able to borrow some money for a short period of time, to make sure you hit that IR deadline, frees you up with your cashflow until that payment [you are waiting on] comes through,” says Bart.
“The fee of using Tax Management NZ is so low and affordable in comparison to the failings of if you ran out of money in that time, or the scramble and the stress, so it’s definitely worth it.
“It’s changed my perception around making these tax payments. It takes the stress off of it.”
And how does dealing with TMNZ compare to dealing with IR?
“You get a bit more of a personal touch with Tax Management NZ because you get a prompt response and it’s not a cookie-cutter [reply].”

Cashflow relief for farmers impacted by flood or drought

Those impacted by flooding in Canterbury or drought elsewhere in New Zealand have another option to manage their cashflow.
It’s called tax pooling.
It lets taxpayers defer their upcoming provisional tax payments to a time that suits them, without incurring interest (currently seven percent) and late payment penalties from Inland Revenue (IRD).
The service – which has been operating with the blessing of the taxman since 2003 – is available through an approved commercial provider such as Tax Management NZ (TMNZ).
The impact of extreme weather
The Government has declared the recent flood in the Canterbury region as a medium-scale adverse weather event.
As those in this part of New Zealand assess the damage and begin the clean-up following the large deluge of rain, a big dry is beginning (or, in some cases, continuing) to bite other parts of New Zealand. The drought has been classified as a large-scale adverse weather event.
Farmers impacted by these contrasting weather events are being encouraged to act early and assess their options if they need assistance.
For those battling drought, some tough decisions around stock and feed will need to be made. In the Canterbury region, flooding only compounds the financial pressure as many were also dealing with drought beforehand.
Cashflow will be important during this difficult period.
Help is available
Managing tax payments will be a key consideration in managing cashflow too.
IRD, to its credit, is exercising some discretion.
It will allow farmers and growers affected by the Canterbury flood to make early withdrawals from the income equalisation scheme.
For those whose current or future income will be significantly affected by drought, IRD will allow late deposits for the 2019-20 income year up to 30 June 2021.
Early withdrawals are also available in the case of a medium-scale adverse event or if someone is suffering serious hardship.
Please note a taxpayer must satisfy certain criteria for IRD to exercise its discretion around the income equalisation scheme.
There's also the option of re-estimating provisional tax.
However, while that allows someone to get a refund of tax they have paid earlier in the year, it does come with some risk.
Free up cashflow by deferring payment of provisional tax
Farmers growers with a May balance date are due to pay their the final instalment of provisional tax for the 2020-21 income on 28 June.
For a small interest cost, someone can use TMNZ to defer this payment.
We make a date-stamped tax deposit to IRD on behalf of a taxpayer on 28 June and the taxpayer pays us when it suits their cashflow.
A taxpayer can either pay the full tax amount at a date of their choosing or enter an instalment arrangement.
When a taxpayer satisfies their arrangement with TMNZ, IRD will treat it as if the taxpayer had paid on time. Any interest and late payment penalties showing on their account will be remitted.
A taxpayer has up to 12 months to pay their 28 June provisional tax with TMNZ.
TMNZ’s interest cost is much cheaper than what IRD charges when someone pays their tax late.

Bright-line test: Don’t get caught by ‘change-of-use’ rule fishhook
Anyone who lives away from their main home for more than a year will be liable to pay income tax on any profit they make from the sale of a residential property sold within the new bright-line period.
That’s because of the introduction of a ‘change-of-use’ rule that came into effect when the Government amended the legislation earlier this year, in its bid to cool rampant property prices in New Zealand.
For salary and wage earners who are renovating their house, away on secondment, or looking to build a property, a hefty and unpleasant tax bill may be lying in wait as a result of this fishhook.
Detailed explanation
Under the bright-line test, an exemption applies if the property a person is selling is their main home.
Prior to 27 March 2021, a property was considered a main home if the owner had lived in it or used it as a main home for at least 50 percent of the time that they owned it.
However, under the new bright-line rules – which apply to a residential property that someone purchases on or after 27 March 2021 and sells within 10 years – homeowners can only be away from their main home for a continuous period of up to 365 days.
Homeowners must treat the days they are away from their main home as ‘non-main home days’.
If someone is away for more than 12 months and then later sells their house within 10 years of acquiring it, the main home exemption will not apply.
This is the 'change-of-use' rule.
It means a person will have to pay income tax on the profit they make from that sale for the period they were not using the property as their main home.
Example
A homeowner sells a property six years after the start of the 10-year bright-line period.
During that six-year bright-line period, they had moved out and rented this house for 15 months while they lived and worked in another part of New Zealand.
Any profit will be split between the 15 months and remaining 57 months during the bright-line period. The homeowner is liable to pay tax on the amount of profit apportioned to the 15-month period.
The impact for salary and wage earners
This has potential – and unpleasant – tax ramifications for salary and wage earners who:
- Renovate their home.
- Live away from their main home due to being on secondment.
- Purchase a section with the intention of building a property, especially if it is going to take more than a year after buying the section to move into their newly built house.
The income a salary and wage earner receives from selling a property is added to their other income sources for that year.
For most, given the eye-watering sums some houses are currently fetching on the market, this will force them into the top tax bracket of 39 percent for that year. The top tax bracket applies to those earning income above $180,000.
There are potential provisional tax ramifications, too.
If the income tax liability from the sale of a property is $60,000 or more, a salary and wage earner will need to pay this by 7 May to avoid incurring Inland Revenue (IR) interest – even if there was no obligation for this person to pay provisional tax during the income year they sell the property.
This is because they fall outside the safe harbour provision.
They can, however, use an IR-approved tax pooling provider such as TMNZ to reduce this interest cost by a notable amount. The savings can be significant.
They will also enter the provisional tax regime during the following income year due to the previous year's income tax liability being greater than $5000.
Anyone who expects to be away from their home for more than 12 months will need to keep accurate records of the number of days they live away from the property as well as any deductible expenses they wish to claim against the property's sale proceeds.
Seek advice
The rules around the taxation of property are complex.
As always, we recommend you speak to an accountant if you have any questions or wish to err on the side of caution.
Make IR interest, late payment penalties disappear
A missed or underpaid provisional tax payment often means a taxpayer is faced with a steep interest cost and potentially late payment penalties on top of what they owe.
However, tax pooling can make that go away.
A big frustration with Inland Revenue (IR) is that it expects taxpayers to pay the correct amount of tax on the dates it sets. No ifs, no buts.
Fail to adhere to this rigid timetable or underpay and you will face the consequences.
IR charges interest – 9.89% as at 8 May 2025 – from the date the payment was due until you pay the outstanding amount.
Late payment penalties may also apply as follows:
- One percent the day after payment was due.
- An additional four percent if the tax amount (including late payment penalties) remains unpaid after seven days.
A tax pooling provider such as TMNZ operates with the blessing of IR. It can be of assistance if taxpayers find themselves in this situation.
Where might this be useful?
In the event you missed your recent 7 May provisional tax payment – or any other instalment relating to the 2020-21 income year, for that matter – we can eliminate any late payment penalties for which you may be liable and significantly reduce the interest you pay.
You make your payment to TMNZ and we apply backdated tax that was paid to IR on the original date(s) it was due against your liability.
The taxman treats it as if you paid on time once it processes this transaction.
This wipes any IR interest and late payment penalties showing on your account.
You have the option of making to TMNZ a one-off payment at a date of your choosing or making regular instalment payments towards your liability over a longer period.
TMNZ gives you up to 13 months to pay your 7 May provisional tax for the 2020-21 income year.
Is your 2020 terminal tax overdue?
You still have time to use TMNZ to reduce the interest cost and eliminate late payment penalties if you have outstanding provisional or terminal tax liabilities for the 2019-20 income year.
However, you will have to act quickly.
Tax pooling legislation gives taxpayers an additional 75 days past their terminal tax date to pay their terminal tax.
If your terminal tax for the 2019-20 income year was due on 7 April 2021, you would have until 15 June to settle owe with TMNZ.
Reassessed by IR
TMNZ can also assist with historic income tax payments and other tax types such as GST and PAYE if you receive a notice of reassessment from IR.
You have 60 days from the date the IR issues this notice to use tax pooling.
Please contact us if you have any questions.
IR payment allocation rules explained
Provisional tax payments made on or before the date of the final instalment for the year are applied to the oldest overdue tax amount first while payments made after the date of the final instalment are applied to the interest owing on any overdue tax first, then the overdue tax amount.
The Inland Revenue (IR) payment allocation rules – which are found in s120F and s120L Tax Administration Act 1994 – also apply to payments made via a tax pooling provider such as TMNZ.
It’s important to understand how they work and differ from one another.
Detailed explanation
Section 120L covers provisional tax payments made on or before the date of the final instalment for the year.
It requires IR to apply a payment to unpaid tax in order from oldest to newest. Please note the unpaid tax amount(s) include late payment penalties.
Section 120F deals with payments that are made after the date of the final provisional tax instalment for the year.
It requires IR to apply payments, in the following order, towards:
- The interest accrued on the oldest unpaid tax amount until that interest is paid.
- The oldest unpaid tax amount until that tax is paid.
- The interest accrued on the next oldest unpaid tax amount until that interest is paid.
- The next oldest unpaid tax amount until that tax is paid.
- To each subsequent arising interest and unpaid tax amount using the pattern above, in time order that relevant unpaid tax arises, until they are paid.
Again, the unpaid tax amount in s120F includes late payment penalties.
The ramifications
These allocation rules mean a taxpayer may well find a tax payment they intended to be destined for a particular instalment date is allocated by IR’s system to earlier unpaid amounts first.
For example, let's say they may make a $10,000 payment on time and in full on 15 January 2021. However, if they failed to pay their 28 August 2020 (P1) provisional tax, then their $10,000 payment will be applied as per s120L to the overdue tax amount (including late payment penalties) at P1 first.
As such, this leaves them exposed to additional (and unexpected) late payment penalties and interest.
It does not matter if the $10,000 payment they made on 15 January 2021 is a date-stamped transfer from the account of a tax pooling provider. Please see sRP19 (1B) Income Tax Act 2007.
In other words, you need to clear the tax liability at all earlier instalment dates first.
How TMNZ can assist with missed provisional tax payments
It's best to purchase from TMNZ the backdated tax to cover the shortfall at the earlier instalment date.
This achieves two things.
Firstly, it eliminates late payment penalties and significantly reduces the interest cost on the underpaid tax.
That’s because the tax you are purchasing from TMNZ was paid to IR on the date it was originally due. IR will treat it as if you have paid on time once it processes your transaction with TMNZ.
Secondly, it ensures that any other payment that was otherwise made on time and in full will be allocated to the particular provisional tax date for which it was intended.
A taxpayer has up to 75 days past their terminal tax date for that tax year to purchase the tax they require.
For example, if you have a terminal tax date of 7 February 2021, you will have until mid-April to settle your 2020 income tax with TMNZ. Those with a 7 April 2021 terminal tax date have until mid-June.

How filing late and losing EOT impacts provisional tax payments
Losing extension of time (EOT) due to filing income tax returns late means someone can only use 105 percent of the previous year's residual income tax (RIT) when calculating their provisional tax payments.
That's because if a taxpayer fails to provide their returns(s) on time, Inland Revenue's (IR) system defaults to using the date by which they were legally due to file the return for that year – not the date on which they furnished the return.
Only if someone files their return(s) within the required timeframe will the actual date of filing be used.
This is important to remember, particularly when using TMNZ’s Tax Calculator.
An overview of IR's system and TMNZ's Tax Calculator
When a taxpayer files their return for the most recently completed year, IR’s system uses the lesser of standard uplift or a third of their RIT to determine the provisional tax instalment amounts due and payable for that year.
As per s120KBB (3B) Tax Administration Act 1994, the standard uplift instalment can either be the lesser of the 105 percent or 110 percent calculation. You can read more about that here.
TMNZ’s calculator follows the same logic as IR's system.
To determine the instalment amounts due and payable, it requires a taxpayer's RIT and filing date information for the past three years:
- The current tax year or most recently completed tax year (e.g. 2020).
- The tax year prior to that (e.g. 2019).
- The tax year two years prior to that (e.g. 2018).
Whereas IR has access to this information, we unfortunately don't. That's why we ask users to enter these details themselves.
If someone was late in providing a return and lost their EOT in any of the years before the current or recently completed tax year, then it’s crucial they know the correct filing date to use, otherwise the calculator will spit out incorrect instalment amounts.
After all, garbage in, garbage out.
Example
A taxpayer with a 31 March balance date decided to use TMNZ’s Tax Calculator to work out the provisional tax payable for the 2019 tax year. They did not pay any income tax for that year and wanted to purchase it from TMNZ to reduce their interest cost and eliminate late payment penalties.
RIT and filing date information for the past three years
| Tax Year | RIT | EOT | Legal date by which they must file their return | Date they file their return | Return status |
| 2017 | $6000 | Yes | 31 March 2018 | 1 May 2018 | Late |
| 2018 | $10,000 | No | 7 July 2018 | 16 January 2019 | Late |
| 2019 | $25,000 | No | 7 July 2019 | 30 June 2019 | On time |
As you can see, the taxpayer has lost their EOT for the 2018 tax year due to filing their 2017 return late. Their 2018 return was also late, so they don’t have EOT for their 2019 tax year either. However, the taxpayer did file the latter year’s return on time.
This means when using TMNZ’s Tax Calculator they must enter into the ‘date of filing’ field the respective legal dates by which they were required to furnish the returns for the 2017 and 2018 tax years.
For the 2017 tax year, this will be 31 March 2018 as their EOT was still applicable. For the 2018 tax year, this will be the non-EOT deadline of 7 July 2018.
Legislation states anyone who has an early balance date (i.e., the period between 1 October and 31 March) must file their return by 7 July if they do not have EOT. Those without EOT who have a late balance date (i.e., the period between 1 April and 30 September) must file their return on the seventh day of the fourth month after their year-end.
As the 2019 tax return was provided within the mandatory timeframe, the taxpayer can use the actual date on which they submitted that year’s return to IR.
Recap: How things should look in TMNZ’s Tax Calculator
| Tax year | RIT | Date of filing |
| 2017 | $6000 | 31 March 2018 |
| 2018 | $10,000 | 7 July 2018 |
| 2019 | $25,000 | 30 June 2019 |
How this impacts provisional tax instalments
In this situation, the 2019 provisional tax instalments will be based on the standard uplift amount as this is lower than a third of the RIT for that year.
However, ALL uplift payments will be based on 105 percent of the 2018 RIT.
That’s because the taxpayer lost EOT for the 2018 tax year and, therefore, was supposed to have filed their return for that year on 7 July 2018 – before the date of their first provisional tax instalment for the 2019 tax year (this being 28 August 2018).
As such, they cannot base any payments off 110 percent of their 2017 RIT.
Therefore, the 2019 instalment amounts due and payable as per IR's system – and what TMNZ's Tax Calculator will tell them to purchase – at each date are as follows:
- 28 August 2018: $3500
- 15 January 2019: $3500
- 7 May 2019: $3500
TMNZ's calculator will also show the taxpayer needs to purchase at their terminal tax date the final balance of $14,500 to settle the 2019 RIT, as their RIT is less than $60,000.
Please note the terminal tax date will have been 7 February 2020 due to them losing their EOT. They would have had 75 days from this date to purchase from TMNZ the 2019 income tax they require.
Don't forget the flow-on effect
It is also important to remember that because there was a requirement to file the 2019 return by 7 July 2019, the taxpayer can only use the 105 percent uplift calculation for their 2020 provisional tax payments.
Again, this is due to the filing date for the 2019 return being before the first instalment date for the 2020 year.
So, using the RIT information above, the standard uplift payments for the 2020 tax year will have been:
- 28 August 2019: $8750
- 15 January 2020: $8750
- 7 May 2020: $8750
For those using the standard uplift method, the 105 percent calculation will continue to be the only option for them to determine provisional tax payments until the taxpayer re-applies for their EOT.
Legislative references
You can find the legislation pertaining to filing dates of tax returns and EOT in s37 and s38 Tax Administration Act 1994.

Harrison Grierson mitigates provisional tax risk
For Matthew Fleming, provisional tax is risky business as it requires a degree of crystal-ball gazing and guesswork.
However, he chooses to mitigate that risk by depositing these payments into TMNZ's tax pool.
It's a “no-brainer” because it gives him a better return if he overpays provisional tax and reduces his interest and late payment penalty costs if he underpays.
More about Matthew Fleming
Matthew is the chief financial officer at Harrison Grierson, one of New Zealand’s leading engineering and design consultancies.
It has offices throughout Aotearoa and predominately provides services locally, with more than 350 staff on the books.
Remarkably, the firm is blowing out 135 candles this year. No one stands the test of time for that long if they ain’t good at what they do.
And Harrison Grierson is good at what it does. A quick peruse of the significant projects it has been associated with during its lifetime is a testament to that.

Provisional tax is 'difficult to predict'
However, like most businesses, it is not immune to the problems provisional tax poses.
Matthew admits calculating the amount of income tax Harrison Grierson must pay Inland Revenue (IR) requires guesswork as its cashflow is up and down at certain times.
He knows the lay of the land during the first quarter – but the rest of the year can go either way.
Matthew says:
“It’s hard enough to try and guess next month’s results, but when you’re having to guesstimate your final year’s tax liability accurately, [it] does take a certain degree of crystal-ball gazing. We try to project our income and where our costs are going to be and having to pay tax on that sort of basis is a little bit of a risk.”
Even more so when one considers the taxman’s wide interest spread. As at the time of writing, they charge 8.35 percent if someone underpays provisional tax and pay just 0.81 percent if they overpay.
In other words, provisional tax is difficult to get right and very expensive when someone gets it wrong.
How Matthew manages that risk
Matthew chooses to deposit Harrison Grierson's provisional tax payments into TMNZ's tax pool.
It's an account operated by an IR-approved tax pooling provider that allows taxpayers to combine their payments. The overpayments from some can then be used to offset the underpayments by others.
TMNZ's tax pool account sits at IR and is overseen by an independent trustee.
Harrison Grierson keeps its date-stamped tax deposits in this account until Matthew confirms its liability for the year. He then arranges for the transfer of these deposits to the firm's own IR account to satisfy what they owe.
If they have surplus tax remaining, he can earn additional interest by selling this to someone who has underpaid (subject to market demand).
Conversely, if not enough tax has been paid, Matthew can reduce the IR interest cost and eliminate any late payment penalties Harrison Grierson faces through purchasing the tax they require from another taxpayer and applying it against the company’s own liability when he arranges their transfers from the pool.
Matthew: 'TMNZ makes provisional tax easier'
Matthew is a big proponent of the benefit TMNZ delivers when his provisional tax calculations go askew.
He says:
“[Tax pooling’s] such a great service in terms of advantaging taxpayers when they are trying to estimate their liabilities and are struggling with it. The ability to get a return when you have overpaid and the ability not to pay such punitive penalty rates when you have underpaid makes it a no-brainer.”
As someone who is having to estimate revenue and costs a lot, Matthew finds it useful that tax pooling gives him the flexibility and control to make payments “as we see fit” based on how the financial year is unfolding, without any considerable downside.
He also likes that he can access refunds faster – and without having to file a return. TMNZ makes it simple for him to manage the payments of the different entities belonging to Harrison Grierson as well.
Matthew recommends tax pooling to other businesses, particularly those with seasonal or volatile income.
“What makes TMNZ an easy choice is it makes the whole provisional tax regime easier to deal with.”

Coffee with Tsarina at Shore Accounting Solutions
Tax pooling is part of the strategy Shore Accounting Solutions employs to assist businesses with managing cashflow and provisional tax payments.
Tsarina Dellow is a chartered accountant at the two-person firm in Amberley, 45 minutes north of Christchurch.
She says paying provisional tax on dates Inland Revenue (IR) prescribes can be hard on small- and medium-sized businesses’ cashflow. That’s particularly the case during the January to May period, when the department awaits payment of two provisional tax instalments (not to mention GST).
Xero’s Small Business Insights reveal January and May are two of the most difficult months in terms of cashflow. August is another. (See a pattern here?)
Tsarina says business owners can come unstuck in this period – particularly if they’re guilty of not squirreling cash away throughout the year.
“Kiwis are often quite bad at saving. They’re not very good at putting money away in the good times, so when they have a bit of a bump – maybe a customer pays late or a supplier puts their costs up – they don’t often have that buffer there. When you don’t have that buffer, things start to go downhill and it gets really stressful for people really, really fast.”
Enter TMNZ
As an IR-approved tax pooling provider, TMNZ allows businesses to make their provisional tax payments when it suits them.
There is no need to worry about late payment penalties. And the interest it charges is fairer than what IR charges when they miss a payment.
Tsarina mentions this service to clients when discussing tax planning and cashflow management if she notices they’re going to encounter any difficulty at certain times of the year.
“If [TMNZ] can help them out with that, we can set a programme in place to even things out during the year,” she says.
“It delivers excellent benefits for people’s cashflow. They’re able to pay their tax as and when it suits them and their business – and they don’t have to worry about the IR always chasing them up. If they can’t meet a provisional tax payment, they can hand it over to TMNZ and pay it when they can.”
About Shore Accounting Solutions
Tsarina has been working at Shore Accounting Solutions for four years. Her colleague Ben Shore founded the firm in 2012.
The duo is big on providing great, technical tax advice and helping North Canterbury businesses and the community grow.
Standard uplift: When 105 percent uplift payments are less than 110 percent payments
Inland Revenue (IR) will sometimes apply the 105 percent standard uplift calculation (CY-1) retrospectively when determining what's due and payable at each provisional tax instalment.
This happens in situations where CY-1 payments turn out to be less than 110 percent uplift payments (CY-2).
When this is the case, IR's system will automatically overwrite the CY-2 calculation once a taxpayer files their return for the previous year.
It will apply what's payable as per the CY-1 calculation to any earlier instalment(s) prior to the date of filing that return. See below.
| Example - uplift instalments for 2020 tax year when 105 percent is less than 110 percent A taxpayer with a 31 March balance date with the following information: 2018 RIT: $35,000 The standard uplift payments due and payable for the 2020 tax year are as follows: 28 Aug 19: $7700 |
TMNZ’s Provisional Tax Calculator also applies this logic when taxpayers enter their residual income tax (RIT) and filing date information.
As you can see, this benefits standard uplift taxpayers.
What if 105 percent is GREATER THAN 110 percent?
When this applies, uplift can be calculated based on the lower CY-2 amount for any instalment(s) due prior to the date the previous year’s return is filed.
This is based on the premise that a taxpayer cannot pay an amount they do not know about and ensures they are not significantly underpaid based on their total uplift amount.
| Example - uplift instalments for 2020 tax year when 105 percent is GREATER THAN 110 percent A taxpayer with a 31 March balance date with the following information: 2018 RIT: $0 The standard uplift payments due and payable for the 2020 tax year are as follows: |
Legislative change to reflect this approach to standard uplift
IR's legal team feels the legislation is not clear in regards to overwriting CY-2 with CY-1 when the latter is lower. As such, there is an amendment in the Taxation (Kiwisaver, Student Loans, and Remedial Matters) Bill that will align the legislation with what the department is doing operationally.
The Bill is due to have its second reading.
Please feel free to contact TMNZ if you have any questions about this.

Jucy Rentals Group say good bye to provisional tax stress
They say you can't make an omelet without breaking some eggs. In this context, a company cannot grow without taking some risks or investing in their business.
Jucy Rentals Group's day-to-day operations highly depend on cash in the bank. It faces a unique challenge when it comes to paying provisional tax. They have to account for two things:

The company's CFO, Jonathan Duncan, found a way to manage cashflow by using TMNZ tax pooling solutions Tax Deposit, Tax Finance and Flexitax to create structure around outgoing payments during the year.
