Tax strategies for NZ software founders and startups

$100k–$500k/yr · 6 strategies

Early-stage software companies have access to some of the most powerful NZ tax tools: the R&D tax credit, R&D loss cash-out for pre-revenue companies, and — once profitable — the shareholder salary structure. Each one requires careful setup, but the numbers can be significant.

General information, not tax advice. Worked examples use fictional personas; figures are illustrative.

01

R&D tax incentive (RDTI)

Requires substantiation
Worked example
Situation

Nikau's Auckland software company put serious money into development, part of it genuinely experimental — new ground, not routine features.

What they did

His accountant separated core R&D (systematic work resolving real scientific or technological uncertainty) from business-as-usual development, and sought general approval before the deadline.

Result

The credit is 15% of eligible spend, but only genuine core R&D counts. Claiming BAU work risks clawback, so the split mattered as much as the size.

Illustrative example — not a real customer. Figures are based on your numbers and rounded.

Legal basis
  • Income Tax Act 2007 subpart LY (R&D tax credits)
  • RDTI eligibility guidance (rdti.govt.nz / IRD IR1240)
Legitimacy test

Activity must meet the core-R&D definition — seeking new knowledge, via a systematic approach, to resolve scientific or technological uncertainty. Business-as-usual software development does not qualify.

02

R&D loss tax credit

Requires substantiation
Worked example
Situation

Nikau's company was pre-revenue and loss-making, with at least 20% of its wage bill going into R&D.

What they did

It registered with IRD before filing and cashed out losses against its eligible R&D spend, instead of carrying them forward.

Result

That returned cash at 28 cents per dollar of eligible spend, traded against the future deduction those losses would have been.

Illustrative example — not a real customer. Figures are based on your numbers and rounded.

Legal basis
  • Income Tax Act 2007 subpart MX (R&D loss tax credits)
  • IRD R&D loss tax credit eligibility guidance
Legitimacy test

Only NZ-resident unlisted companies qualify (sole traders, partnerships and look-through companies are excluded). The company must be in a tax-loss position and spend at least 20% of total labour expenditure on R&D.

03

Shareholder salary structure

Anti-avoidance: get advice
Worked example
Situation

Nikau's company cleared well past the $180,000 top personal tax band, and he had to decide how much to take as salary versus leave in the company.

What they did

He set his salary at a commercially realistic market rate for the work he actually performs, and documented the genuine business reason (funding next year's hires) for the profit that stayed in the company.

Result

The arrangement holds up because the salary reflects the role and the retained profit serves the business, not just tax deferral. An artificially low salary is the exact pattern IRD attacks under the anti-avoidance rule — Penny & Hooper turned on it.

Illustrative example — not a real customer. Figures are based on your numbers and rounded.

Legal basis
  • Income Tax Act 2007 s BG 1 (general anti-avoidance) & s GA 1 (reconstruction)
  • Penny & Hooper v CIR [2011] NZSC 95 (artificially low salaries = avoidance)
  • Ben Nevis Forestry Ventures v CIR [2008] NZSC 115 (Parliamentary-contemplation test)
Legitimacy test

Salary must be a commercially realistic reward for the work actually performed; retaining profit must serve a genuine business purpose (not only tax deferral); any income split to an associate requires genuine share ownership.

04

Provisional tax and UOMI

Worked example
Situation

Priya's first good year consulting, invoicing around $30k, left her owing more than $5,000 of residual income tax — which made her a provisional taxpayer the next year.

What they did

She paid the three standard-uplift instalments on time rather than gambling on her own estimates.

Result

That kept her in the safe harbour, so no use-of-money interest on the year-end square-up. The instalments were never a shock because she'd set money aside monthly.

Illustrative example — not a real customer. Figures are based on your numbers and rounded.

Legal basis
  • Income Tax Act 2007 s RC 3 (provisional tax); Tax Administration Act 1994 ss 120C, 120D (use-of-money interest)

05

GST zero-rating for exports

Requires substantiation
Worked example
Situation

Ruth builds Shopify stores from Dunedin for clients in Australia and the US, and had been adding 15% GST to every invoice.

What they did

She confirmed each client was a non-resident who was outside New Zealand while she did the work, with nobody in NZ receiving the service, then zero-rated those invoices.

Result

The GST line came off her export invoices. The checks are the point: get residency wrong and you still owe the GST, plus interest.

Illustrative example — not a real customer. Figures are based on your numbers and rounded.

Legal basis
  • Goods and Services Tax Act 1985 s 11A(1)(k) — zero-rating of services to non-residents outside NZ
Legitimacy test

Services are zero-rated only if the recipient is a non-resident who is outside New Zealand at the time the service is performed. Services contracted by a non-resident but received by a third party in NZ are not zero-rated.

06

Investment Boost (Budget 2025)

Worked example
Situation

Tama wires new builds around Hamilton and bought new test gear after 22 May 2025, each item over $1,000 excl-GST.

What they did

His accountant applied the Investment Boost, an extra 20% deduction in year one on top of normal depreciation, and confirmed each asset was new and qualified before filing.

Result

That brought a fifth of the asset cost forward as a year-one deduction instead of waiting on the depreciation schedule.

Illustrative example — not a real customer. Figures are based on your numbers and rounded.

Legal basis
  • Budget 2025, Investment Boost — IRD guidance pending IS publication
