CTM92640 - CTSA: quarterly instalments: company procedure

Companies that believe that they are, or may be, liable to make quarterly instalment payments should review the position at least at each instalment due date.

  1. If the company estimate of the total liability indicates that it has paid too little tax on previous instalment due dates it should make a top-up payment.
  2. If the company estimate indicates that it has paid too much, it can deduct the excess from the current payment.
  3. If the cumulative payments exceed the cumulative liability, it can claim repayment under Regulation 6. (see CTM92650).

A company can make a top-up payment or a repayment claim at any time.

  • Companies can make quarterly instalment payments by any electronic method.

An officer who makes a Revenue determination and considers that the company should pay the tax in quarterly instalments should refer to CTM95370.
