COM101150 - Penalties: penalty determinations: time limits
Flat-rate penalties
You may determine a flat-rate penalty under the provisions of S103(4) Taxes Management Act (TMA) 1970 at any time within six years after the date the penalty was incurred or began to be incurred.
As an example, assume that A Ltd is required to deliver a return for the Accounting Period (AP) ended 31/12/2019. The filing date is 31/12/2020, but it fails to deliver it until 01/02/2021.
A flat-rate penalty is incurred on 01/01/2021 and it can be determined at any time up and including 01/01/2027.
Tax-related penalties
A tax-related penalty may be determined under the provisions of S103(1)(a) and (b) TMA 1970, at any time up to the later of six years after the date the penalty was incurred or three years after the final determination of the tax on which the penalty is based.
As an example, assume that B Ltd is required to deliver a return for the AP ended 31/12/2021 by the filing date, 31/12/2022.
It fails to deliver its return until 01/08/2023 and makes no payment before that date.
The liability for the AP ended 31/12/2021 is finally determined on 01/01/2027 showing tax due of £10,000.
A tax-related penalty can be determined at any time up to 01/01/2030, being three years after the relevant amount of tax is finally determined. This is later than 01/07/2029, six years after the penalty was incurred.
Appropriate penalties will have been automatically brought into charge as they arose, unless system inhibitors prevented this.
