Tax calculation

This screen is accessed from within the Tax Return.

The Tax Calculation tab is available for Individuals (SA100) (R40) and Trust SA (SA900) tax returns. It shows the tax calculation based on the current tax return information entered.

  • Select Download PDF to view or download a PDF copy of the computation.

Included on this tab is the option to view the estimated tax liability for the following tax year, based on the current figures entered.

  • Select View estimated liability for [next tax year].

The calculation is divided into sections:

  • Income received - this information is entered via the Data Input tab by selecting the relevant section.

  • Personal allowances - Taxfiler by IRIS will enter the value applicable for the tax year being completed.

  • How I have worked out your Income Tax - Taxfiler by IRIS will display a breakdown of the values allocated to each rate band, and a total of the income tax charged.

  • Any reliefs and allowances will be shown.

  • Income Tax due after allowances and reliefs - Taxfiler by IRIS will show the amount of tax due after allowances and reliefs.

  • Tax deducted - where tax has already been deducted from income, this will be subtracted from the Tax due after the allowances and reliefs, and the total Income Tax due will be shown.

Payments on account are not shown on the tax calculation and are accessed via the Status tab and then Tax payments made.
