With global and local economic pressures, many Kiwi businesses are struggling to meet their provisional tax obligations on 28 August.
TMNZ’s flexible tax payment solution is a way to free up working capital and pay tax when it suits your business.
We can also help with any missed or underpaid payments for the 2026 financial year.
Unlike paying Inland Revenue’s lump sum on their schedule (or big bank fees), we let you defer or spread payments, avoid penalties, save on interest and keep your business moving through this season!
If your business’s total tax liability is less than $60, 000, spreading your payment over a maximum of 6 months with TMNZ, will cost you less than paying Inland Revenue directly.
