COM90025 - Payments: processing payments: the payment record: Instalment Due Date

An instalment due date is a date on which a Quarterly Instalment Payment is due and the dates are as follows:

For a 12-month Accounting Period (AP) for a ‘Large’ company


Instalment 
 Instalment due date 
First 
 6 months and 13 days from the start of the AP 
Second 
 3 months from the first instalment due date 
Third 
 3 months from the second instalment due date 
Final 
 3 months and 14 days from the end of the AP 

For an AP of less than 12 months: 

  • the final instalment is due, as normal, 3 months and 14 days from the end of the AP
  • earlier instalments are due only if the dates for the earlier instalments (as shown above) fall earlier than the date of the final instalment

This means that an AP of: 

  • 3 months or less, will require only the final instalment
  • between 3 months and 1 day and 6 months, will require only a first and a final instalment
  • between 6 months and 1 day and 9 months, will require a first, second and final instalment
  • more than 9 months, will require all four instalments

Please note that:

  1. for Quarterly Instalment Payment cases that end before 01/07/02 there is a transitional period.  During this period there is a balance of tax payable on the normal due date
  2. after the transitional period the final payment due date will be 3 months and 14 days from the AP end date.  There will not be a balancing payment at the normal due date
  3. for all other purposes the normal due date remains unchanged at 9 months and 1 day from the AP end date

For more information see section ‘Quarterly Instalment Payments’ (COM95000 onwards) in business area ‘Payments’.


For a 12-month Accounting Period (AP) for a ‘Very Large’ company


Instalment 
 Instalment due date 
First 
 2 months and 13 days from the start of the AP
Second 
 3 months from the first instalment due date 
Third 
 3 months from the second instalment due date 
Final 
 3 months and 14 days from the end of the AP 

For an AP of less than 12 months 

If the accounting period is shorter than 12 months, the rules apply to ensure that the final instalment payment falls within the accounting period. 

Subject to exceptions, the last instalment date will depend on which day of the month the end of the accounting period falls — if the accounting period ends on: 

  • the last day of the month, the last instalment will be due 14 days after the end of the preceding month
  • a day for which there is a corresponding date in the preceding month, the last instalment falls 14 days after that date in the preceding month
  • a day for which there is no corresponding day in the previous month, the last instalment is due 14 days after the last day of the previous month
