1. What is HMRC Interest On Late Payments?

HMRC (Her Majesty's Revenue and Customs) interest on late payments is charged when tax payments are not made by the due date. This calculator helps estimate the interest amount payable on overdue tax payments.

2. How Does the Calculator Work?

The calculator uses the HMRC interest formula:

Where:

• \( I \) — Interest amount (currency units)
• \( A \) — Original amount due (currency units)
• \( R \) — Annual interest rate (%)
• \( D \) — Number of days late (days)

Explanation: The formula calculates daily interest by dividing the annual rate by 365 days, then multiplies by the number of days the payment is late.
