Do I need to submit a Self Assessment?
HMRC expects everyone who has been sent a ‘Notice to File’ to submit a Self Assessment.
In theory they will only send a Notice to File to people who need to submit one, however you may need to update their records.
People who need to submit a Self Assessment are:
Sole Traders
Members of a Partnership
Anyone with income above £100k
Anyone with income that has not been taxed at source (eg trading income, dividend income, rental income, Capital Gains)*
Anyone liable for Higher Income Child Benefit Charge
If you have received a Notice to File and do not fall into any of the categories above, a call to HMRC can get the Notice to File cancelled.
If you fall into the categories above and have not received a Notice to File, it is your duty to inform HMRC that you need to declare income via Self Assessment. Failing to notify HMRC can result in a fine.
*Income taxed at source is usually only PAYE and interest income.
