Rental Property Tax Records in NZ: Deductions and Depreciation

Rental property tax depends on the property, ownership structure, income year and expense. Keep clear records and check current Inland Revenue guidance or ask a qualified tax adviser before filing. This overview is general information, not tax advice.

Keep records for rental income and expenses

Record rent received and keep invoices, receipts, loan records and other documents that explain each amount. Inland Revenue's rental income guidance describes the current rules and record keeping. The treatment of a cost can depend on whether it is a deductible expense, capital expenditure or private use.

Check the interest rules for your property

Interest deductibility is subject to general deductibility requirements and residential property interest rules. Do not assume that every interest cost is deductible in full. Check Inland Revenue's current residential property interest rules for exclusions, timing and any property-specific conditions.

Building and chattel depreciation

Depreciation treatment differs between residential buildings and separately identifiable chattels. Inland Revenue publishes current depreciation guidance and rates; identify assets and use the applicable rate rather than treating all items in a property as one asset. Ask an adviser about asset allocation when a property is purchased or work is completed.

Use records to support your decisions

RentManager can help organise rent records, expenses and documents for review and handover. It does not decide whether a cost is deductible or prepare tax advice. See current plans and the rental record keeping guide. Compare property management quotes against the actual services and costs you expect to use; a software subscription does not replace an agency's physical visits or delegated work.
