Investment Boost – Immediate 20% deduction for NEW assets
Key Features
- The amount a person can deduct in the income year the asset is first available for use:
- 20% of the cost of the asset, plus
- the amount of the usual depreciation deduction that would otherwise apply but calculated as if the cost of the asset were reduced by 20%
- The asset must be used (or available for use) for the first time on or after 22nd May 2025
- The asset must be NEW to NZ – not previously used in New Zealand for any purpose, other than as trading stock
- NEW investment assets include:
- all depreciable property except residential buildings and Fixed Life Intangible Property (FLIP)
- improvements to depreciable property (other than to residential buildings and FLIP)
- primary sector land improvements
- assets acquired as petroleum development expenditure and mineral mining
- development expenditure (except rights, permits or privileges)
- new-build commercial and industrial buildings that would otherwise have a depreciation rate of 0%
- second-hand assets purchased from overseas
- listed horticultural plants
- Note for new investment assets that are not depreciable property, eg. development expenditure, the deduction would only be available for expenditure incurred from 22nd May 2025
- Some or all of the deduction may be recoverable if the asset is disposed of (or deemed to be disposed of) and the consideration is more than the asset’s adjusted tax value
- Deductions for primary sector land improvements would not be recoverable, as per the treatment under existing amortisation rules
- Assets used partly for business could be eligible, but the deduction will need to be apportioned
