⚠ Industrial Building Allowance: Strict Qualifying Rules
Not all industrial-zoned property qualifies for Industrial Building Allowances. The building must be used for qualifying purposes (manufacturing, storage, etc.) and at least 80% of floor area must meet the test. Misclassification triggers clawback assessments.
Common Challenges
Industrial Building Allowance Eligibility
IBA under s.33 IRO provides 20% initial + 4% annual allowances. Many owners are unaware of the strict qualifying use requirements or fail the 80% floor area test.
⚠ Risk: Incorrect IBA claims → clawback with interest and penalties
Revitalisation & Conversion
Converting industrial buildings to hotels, offices, or data centres has complex tax implications including balancing charges on any allowances previously claimed.
⚠ Risk: Unplanned conversion → unexpected balancing charge tax
Self-Use vs Letting
Owner-occupiers claim allowances differently from landlords. Mixing self-use and letting requires careful apportionment of allowances and rental income.
⚠ Risk: Wrong apportionment → disallowed deductions on review
Data Centre Classification
Modern data centres straddle industrial and commercial classifications. Whether your data centre qualifies for IBA depends on specific IRD guidance in DIPN 10.
⚠ Risk: Wrong classification → denied allowances or double taxation

Frequently Asked Questions
What qualifies as an industrial building for IBA purposes?
Under s.33 IRO, an industrial building includes buildings used for manufacturing, processing, storage, or transport of goods. At least 80% of the floor area must be used for qualifying industrial purposes. The rules are detailed in DIPN 10 and DIPN 49 — eligibility requires careful assessment.
What is the rate of Industrial Building Allowance?
The initial allowance (IA) is 20% of qualifying capital expenditure in the year the building is first used. Annual allowances (AA) are then 4% per year on the original qualifying cost, giving full recovery over 25 years. A balancing allowance or charge arises on disposal.
Can I claim IBA if I let the building to a tenant?
Yes, if the tenant uses the building for qualifying industrial purposes, you as landlord can claim IBA. You must be able to demonstrate the tenant's use meets the qualifying criteria, so tenant use confirmations should be obtained and retained.
What happens when I sell an industrial building?
On disposal, a balancing allowance or balancing charge is computed. If the sale proceeds are less than the tax written-down value, a balancing allowance (additional deduction) arises. If proceeds exceed the written-down value, a balancing charge (clawback) is assessed. This can significantly affect the net proceeds of sale.
Are data centres treated as industrial buildings?
IRD has accepted that purpose-built data centres used for storage and processing can qualify as industrial buildings under s.33 IRO. However, the qualifying use test and 80% floor area requirement still apply. Colocation facilities that primarily provide office space for clients may not qualify. Seek specific advice before filing.
What are the tax implications of the industrial building revitalisation scheme?
The Government's revitalisation scheme permits industrial buildings over 15 years old to be converted to non-industrial uses. From a tax perspective, conversion triggers a balancing charge on previously claimed IBAs based on the market value at the time of change of use. Pre-conversion tax modelling is essential.
