Provisional Tax Overview
Provisional tax is a system that allows taxpayers to pay their income tax in instalments throughout the year, rather than in a single lump sum at the end. This approach aids in managing cash flow and prevents the burden of a substantial tax payment after the tax year concludes. In New Zealand, if your residual income tax (RIT) – the amount of tax owed after deducting any PAYE and other credits – is more than $5,000, you’re required to pay provisional tax in the following year.
Methods of Calculating Provisional Tax
There are four methods available for calculating provisional tax:
- Standard Method (Uplift Method): This default method calculates provisional tax based on your previous year’s RIT plus an uplift of 5%. If your prior year’s return isn’t filed before the first instalment, the calculation may use the RIT from two years ago plus 10%.
- Estimation Method: You can estimate your RIT for the current year if you anticipate a significant change in income. It’s crucial to monitor your income closely, as underestimating can result in interest charges and penalties.
- Ratio Option: This method is suitable for businesses registered for GST on the invoice or hybrid basis. It calculates provisional tax as a percentage of your GST taxable supplies, aligning tax payments with cash flow.
- Accounting Income Method (AIM): designed for small businesses with a turnover under $5 million, AIM allows you to pay provisional tax based on your actual profits as they are earned, using approved accounting software.
Payment Dates
The due dates for provisional tax payments depend on your balance date and the method chosen. Typically, for taxpayers with a standard 31 March balance date using the standard or estimation methods, payments are due in three instalments:
- 28 August
- 15 January
- 7 May
If you’re registered for GST and file six-monthly returns, you may have two instalments aligning with your GST due dates.
Avoiding Penalties and Interest
To prevent penalties and interest charges:
- Timely Payments: Ensure all provisional tax instalments are paid by the due dates.
- Accurate Estimations: If using the estimation method, regularly review and adjust your income projections to avoid underestimation.
- Consider AIM or Ratio Options: These methods can provide more flexibility and align tax payments with actual income, reducing the risk of underpayment.
- Voluntary Payments: In your first year of business, consider making voluntary tax payments to spread the tax burden and potentially qualify for an early payment discount.
- Professional Advice: Consult with a tax professional to determine the most suitable provisional tax method for your circumstances and to ensure compliance with tax obligations.
