Yes — FD interest is subject to 10% Withholding Tax (WHT) deducted at source by the bank from 1 April 2025 (IRD Circular SEC/2025/E/02), which is a final tax for most individuals. The calculator above already applies this 10% deduction.
How often are these rates updated?
Automatically. We fetch the published bank tariff daily and this page always renders the latest successful fetch — a failed update keeps the last good data rather than showing nothing. The "effective" date under each rate block tells you exactly what is live.
