Investment Boost: What New Zealand Businesses Must Know About Accelerated Depreciation Changes

From 22 May 2025, the New Zealand Government introduced the Investment Boost - a form of accelerated depreciation allowing businesses to deduct 20% upfront on new depreciable assets, then claim standard depreciation on the remaining value. This presents a powerful tax planning opportunity for your business.

What Has Changed?

The May 2025 Budget introduced the Investment Boost in the Taxation (Budget Measures) Bill No 2, effective immediately.

  • Businesses can claim a 20% immediate deduction on new (or imported-new) depreciable assets purchased or available from 22 May 2025
  • Depreciation continues on the remaining 80% value at normal rates.

Qualifying assets include:

  • New machinery, tools, equipment, vehicles
  • Commercial and industrial buildings (even with 0% depreciation)
  • Land improvements, forestry plantings, aquaculture, and petroleum/mining development

Excluded assets include: previously used NZ assets, residential buildings, land, intangible assets, and low-value assets already immediately deductible

Why It Matters for Your Cashflow & Tax Planning

Accelerated depreciation isn't about giving bigger deductions overall (except in the case where the depreciation rate is 0%) - it brings deductions forward, improving cashflow and reducing tax payable in the year of purchase.

Example 1: Asset costing $100,000 with 10% straight line depreciation rate:

Without Boost: $10,000/year for 10 years.

With Boost: Year 1 = $20,000 (boost) + $8,000 (10% of the remaining ) = $28,000; then $8,000 annually for 9 years.

Example 2: Commercial Property costing $1m with 0% deprecation, sold for $1.1m 5 years later.

Without Boost: $0 depreciation throughout the lifetime. No adjustment at sale.

With Boost: Year 1 = $20,000; $0 for years 2 - 4; -$20,000 in year 5.

Practical Strategies to Maximise Benefits

1. Plan Asset Purchases Around the Boost Window

Make sure assets are new to NZ, purchased after 22 May 2025, and “available for use” before year-end.

2. Choose Asset-by-Asset

The Boost is optional per asset; evaluate if immediate or gradual write-off fits your profit profile.

3. Utilise Commercial Building Eligibility

Typically commercial properties are non-depreciable, but now you can claim 20% upfront (of the building, not the land).

4. Track Mixed-Use Apportionment

Partial business use requires proportionate deductions; asset sale may trigger clawback if use changes.

5. Watch for Clawbacks on Disposal

If you sell an asset above its adjusted tax value, part of the Boost may be recaptured as income.

Frequently Asked Questions

What assets qualify for the Investment Boost?

New assets to New Zealand such as machinery, equipment, vehicles, and commercial/industrial buildings purchased after 22 May 2025. Residential buildings and land are excluded.

Does the Investment Boost increase my total deduction?

Generally no, it simply accelerates the deduction to the first year (timing benefit). However, for commercial buildings with 0% depreciation, it provides a deduction where there previously was none (though this may be clawed back upon sale).
