Under new rules, capital gains tax (CGT) on disposals of UK residential property must be reported by 31 July to avoid a penalty.
You may have to pay Capital Gains Tax if you make a profit (‘gain’) when you sell (or ‘dispose of’) property that’s not your home. For example, buy-to-let properties, land, or inherited property.
For UK property disposals made from 6 April 2020, you have 30 days after the property’s completion date to report and pay any Capital Gains Tax due on your UK property disposals.
Due to COVID-19, there will not be a late filing penalty for any transactions completed on or after 6 April 2020 to 1 July 2020 and reported up to 31 July 2020. This means that any CGT on sales between 6 April and 30 June 2020 is due on 31 July 2020. CGT due on sales from 1 July will be due 30 days after the sale.
Transactions completed from 1 July 2020 will receive a late filing penalty if they are not reported within 30 calendar days. Interest will be charged if the tax remains unpaid after 30 days for all transactions from 6 April 2020.
