Filing obligations and deadlines: at a glance
Capital Gains made on UK residential property disposals, including gains made by Non-Resident taxpayers of indirect disposals of interests in a 'UK property rich' entity, must be declared on HMRC's online CGT disposal return, and the tax paid, using the Capital Gains Tax UK property disposal service, within:
- 60 days if the completion date was on or after 27 October 2021.
- 30 days if the completion date was between 6 April 2020 and 26 October 2021
Other Capital Gains are reported under Self Assessment on or before 31 January following the year of assessment.
UK residential gains which have been reported through HMRC's '60 day reporting' service must also be included on the Self Assessment return, if the taxpayer is required to complete one. Details of the tax already paid must be declared on the Self Assessment return along with the CGT disposal return's reference number.
This means that there may well be up to two filing obligations and two tax payments, where a balancing payment is due under Self Assessment

Late payment: Time to pay agreements
If the taxpayer makes a Time to Pay agreement with HMRC, the penalty is suspended.
- The taxpayer will become liable to the penalty if the suspension agreement is broken.
Appeal
- The taxpayer has 30 days to lodge an appeal with HMRC against a tax penalty. This was extended by three months for COVID-19-related delays for the 2019-20 tax year.
- A Late appeal may be accepted at the discretion of HMRC or the tribunal judge.
The legislation relevant to each type of penalty provides for the appeal process and it is advisable first off to ensure that any penalty charged has been made correctly according to the legislation.
HMRC will not challenge any late filing penalty appeal provided that there is a Reasonable excuse for late filing and that an appeal has been made.
Appealing a penalty can be far from straightforward, as there are numerous grounds for appeal and technical arguments that can assist the taxpayer.
Special reduction
- Upon appeal, HMRC has a statutory requirement to consider whether any special circumstances exist and if so, it may override the statutory penalties and reduce them as it sees fit.
- See Appeals: Grounds for Appeal Toolkit
