New Zealand’s provisional tax framework diverges from commercial cash flow cycles, prompting calls for a reform, according to a survey commissioned by Tax Management New Zealand (TMNZ) and Chartered Accountants Australia and New Zealand (CA ANZ).
The survey of 334 accountants awarded the current regime a fairness score of 6.2 out of 10.

Around 81% of respondents reported that client liquidity constraints directly undermine on-time tax compliance, with 77% singling out the 15 January instalment as an acute pressure point.
That deadline coincides with the summer holiday shutdown, a period when many businesses experience lower revenue alongside concurrent goods and services tax (GST) obligations and elevated overhead.
Approximately 95% of surveyed professionals noted that some portion of their client base risks late or insufficient tax remittances every year.
The research also found that 98% of them managed an acute payment issue including statutory interest charges, missed deadlines or cash deficits during the past 12 months.
The compliance burden also creates an operational bottleneck for advisers, with 75% reporting that their heaviest workload falls between late March and early May, when provisional tax liabilities collide with annual financial reporting and GST deadlines.
The findings highlight demand for regulatory and operational flexibility, with 86% of accountants supporting mechanisms to defer instalment dates without incurring penalties.
Over the next two to three years, nearly 75% of practitioners anticipate significant changes to tax management workflows, driven by automation and deeper data integration.
The survey was conducted online by Curiosity Company from 21 July to 9 August 2026 by recruiting participants through the TMNZ, CA ANZ and ATAINZ.
CA ANZ’s NZ Tax and Financial Services leader John Cuthbertson said: “A rating of 6.2 out of 10 for fairness tells its own story.
“Three frustrations dominate: misalignment with business cash flow, payment dates that don’t reflect commercial reality, and the penalties and interest businesses can face when things don’t go to plan.
“The good news is the system doesn’t need to be rebuilt from scratch. Practical changes to improve flexibility could make a significant difference for businesses and the accountants who support them.”
