Personal & company income tax
Whether you’re an individual with business, rental or investment income on top of wages, a sole trader or a company, we bring the year’s income together and file it with IRD, checking for expenses and deductions that are easy to miss.
- Individual income tax returns (IR3), including business, rental, interest, dividend and overseas income
- Business income for sole traders
- Company income tax returns (IR4)
- Provisional tax planning and payment dates
Filing through a tax agent usually moves your income tax return deadline from 7 July to 31 March the following year. It’s IRD’s extension of time for tax agents’ clients, and you need to be linked to the agent before the original deadline.
