About Double Taxation Relief Calculator

Relief for tax paid abroad is normally limited to the domestic tax on the same income, so a higher foreign rate leaves part of the foreign tax unrelieved. That excess is generally lost rather than refunded.

Formula

Ordinary credit method

Relief = min(foreign tax paid, domestic tax on that income)

Worked example

  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • Tax figures are estimates based on the rates, caps and thresholds you enter. Real rules differ by jurisdiction and change every year, and personal circumstances alter the outcome. This is not tax or financial advice — confirm with a qualified adviser.

Frequently Asked Questions

Why is relief capped?

Because the domestic authority will not refund another country's tax. It only gives up its own claim on that income.

Is exemption ever better than credit?

Where the foreign rate is lower, an exemption method leaves the taxpayer better off — the treaty decides which applies.
