RD 20C: Payments of recalculated main benefit

You could also call this:

“How tax is calculated on back-payments of main benefits”

You might receive a payment called a recalculated main benefit payment. This happens when the government looks at the main benefit you got in past years and decides you should have received a different amount. They’ll pay you the difference in one lump sum.

When you get this payment, you’ll need to pay some tax on it. The amount of tax you pay is worked out using a special formula. This formula takes into account how much tax the government already took out of the payment before giving it to you.

The formula looks at two things:

  1. The tax deduction: This is the amount of tax the government department that handles social security (called MSD) has already paid to the tax department for your payment.
  2. The received amount: This is how much money you actually got from MSD after they took out the tax.

The government uses these two numbers to figure out the right tax rate for your recalculated main benefit payment. This way, you only pay the correct amount of tax on this extra money you’re getting.
