Self Employed full/short 17 - If your business ceased after the 5 April 2020 but before 6 April 2021
If you've stopped working for yourself, you're taxable on any profits for the period beginning on the day after your last accounting period and the date your business ceased. You may be entitled to a tax relief called 'overlap relief'.
You must also tell us the date you stopped working for yourself. If you no longer need to pay Class 2 National Insurance contributions, we will arrange for your bills to stop.
