Standard costs for home-based services

Home-based service providers meeting certain criteria can choose to use standard costs instead of their actual expenses when calculating their taxable income.  Inland Revenue reviews the standard costs annually for movements in the Consumers Price Index.

These determinations set the standard costs for home-based service providers.

Amounts calculated in accordance with these standard cost household service determinations are treated as expenditure incurred in providing the relevant services.  For any income year, a taxpayer can choose to use these standard costs instead of their actual expenses, provided the criteria in the determinations are met.
