the problem
Managing provisional tax has always taken more effort than it should.
Checking client positions, upcoming deadlines and compliance gaps can mean moving between Inland Revenue, spreadsheets and several practice systems. It takes time. And too often, issues only become visible after they need attention.

what’s changing
Built around the way your practice already works
The new TMNZ platform works alongside the tools your team already uses. It brings provisional tax into one connected, practice-wide view, so your team can spend less time cross-checking information and more time helping clients.
 | Your accounting software / practice management systems stay central |
| Connect once and see provisional tax positions in one connected view |
| Status at a glance: compliant, upcoming deadlines, attention needed |
| No subscription or platform fee for your firm or your clients |
what’s changing
Move from reactive admin to proactive tax management
Portfolio-level visibility Compliance gaps that used to surface only after a penalty become visible early, while you can still act. Fewer cross-checks Phone calls, spreadsheet cross-checks and status updates: reduced to a few clicks, or gone. Less chasing Spend less time hunting for information across systems, cutting unbillable hours.
what practices are saying
“A lot of staff time was going into just getting an accurate view of our clients’ tax positions – so we could see who needed chasing for payment. As a firm that prides itself on proactive advisory, that’s not where we want to be spending our energy. We partner with people who make our lives easier, and that is where TMNZ comes in. Then we can get back to what actually matters: our clients.”
Marcus Murdoch — Managing Director at Croys

FAQs

Once the platform launches: two things. First, clearer visibility across your client book - provisional tax positions, payment status, and what needs attention, in one place. Second, greater efficiency - the platform is designed to make it easier to identify issues and take the right next step, instead of relying on manual spreadsheet checking. We’ll give your team a clear view of what to expect before the change happens.”
