RDTI vs RDLTC: Which R&D Scheme Is Right for Your Business?

Comparing New Zealand's two R&D incentive schemes - the R&D Tax Incentive and the R&D Loss Tax Credit - to help you decide which one to claim.

New Zealand offers two distinct R&D incentive schemes, and many businesses don't realise they may be eligible for both. Understanding the difference between the R&D Tax Incentive (RDTI) and the R&D Loss Tax Credit (RDLTC) is crucial for maximising your returns.

Quick Comparison

The RDTI provides a 15% tax credit on eligible R&D expenditure. It's available to profitable and loss-making businesses alike and is the broader of the two schemes.

The RDLTC converts a portion of your tax losses attributable to R&D into a cash payment. It's specifically designed for businesses that are not yet profitable - typically startups and high-growth companies that are investing heavily in R&D but haven't reached profitability.

The R&D Tax Incentive (RDTI)

Best for: Businesses of any size with at least $50,000 in annual R&D spend.

The RDTI is straightforward: spend money on qualifying R&D, get 15% back as a tax credit. If the credit exceeds your tax liability, you receive a cash refund.

Key features:

  • 15% credit on eligible R&D expenditure
  • Minimum $50,000 spend threshold
  • Available to both profitable and loss-making companies
  • Requires General Approval from MBIE
  • Credit applied against income tax, excess refunded

The R&D Loss Tax Credit (RDLTC)

Best for: Pre-revenue and loss-making companies with significant R&D expenditure.

The RDLTC works differently. Instead of a credit on expenditure, it allows you to cash out a portion of your tax losses that are attributable to R&D. The cash-out rate is the company tax rate - currently 28%.

Key features:

  • Converts R&D-related tax losses into cash at 28%
  • No minimum spend threshold (but must have eligible R&D)
  • Only available to companies in a tax loss position
  • Capped at the lesser of your R&D expenditure or tax loss
  • Maximum claim linked to total R&D spend
  • Must file with your income tax return

Can You Claim Both?

Yes, but there are important rules to prevent double-dipping. The same expenditure cannot be counted under both schemes. However, if you have R&D expenditure that exceeds the amount used for your RDLTC claim, you can potentially claim the RDTI on the remainder.

In practice, many early-stage companies find the RDLTC more valuable because the 28% cash-out rate is almost double the RDTI's 15% credit rate. If you're in a tax loss position and your R&D spend is significant, the RDLTC typically delivers a larger cash benefit.

Decision Framework

Claim the RDLTC if:

  • Your company is in a tax loss position
  • You have significant R&D expenditure
  • You want to maximise the cash-out percentage (28% vs 15%)
  • You're a startup or high-growth company not yet profitable

Claim the RDTI if:

  • Your company is profitable (or has minimal tax losses)
  • Your R&D spend is at least $50,000
  • You want a straightforward credit against your tax bill
  • You have R&D expenditure beyond what the RDLTC covers

Consider claiming both if:

  • You have R&D expenditure exceeding your tax losses
  • You want to maximise your total benefit across both schemes

A Practical Example

Consider a software company with:

  • $400,000 in R&D expenditure
  • A tax loss of $300,000

RDLTC claim: The company can cash out $300,000 (the lesser of R&D spend and tax loss) at 28%, receiving $84,000 in cash.

RDTI claim on remainder: The remaining $100,000 of R&D expenditure ($400,000 minus $300,000 used for RDLTC) could qualify for the RDTI at 15%, giving an additional $15,000 credit.

Total benefit: $99,000 - significantly more than claiming either scheme alone.

Getting Started

The application processes for both schemes involve documenting your R&D activities, demonstrating eligibility, and filing the appropriate returns. At R&D by Automatax, our platform helps you through both processes, using AI to identify eligible activities and generate the required technical documentation.

Whether you're a startup exploring the RDLTC for the first time or an established business looking to optimise your RDTI claim, understanding which scheme - or combination of schemes - works best for your situation is the first step to securing your credits.
