How to use this calculator
- Enter the dues provided in accounts and the dates and amounts actually paid.
- Choose the type of due and the payment date to match your situation.
- Read the allowed amount, the disallowed amount and the amount allowed later in the result.
Payment before the due date of filing the return is normally the test; confirm the date for each item.
The result is an estimate for the figures you enter. It is not a filed return, a certificate or professional advice. Rates, thresholds and section numbers change with each Finance Act, and the Income-tax Act, 2025 applies from 1 April 2026 with new section and form numbers.
