Sending a return

You can send a tax return by either: 

• submitting an online return  
• sending a paper return 

You can get help filling in your return. 

When to send your tax return 

Check the filing deadlines. The deadline for sending a paper return is before the deadline for an online return. 

You can send your return any time after 5 April. Sending it earlier means you: 

• find out what you owe 
• can budget - if you want to make weekly or monthly payments 
• have time to pay your bill by 31 January 
• can set up a payment plan, if you do not think you can pay on time

Submit an online return  

You can file your Self Assessment tax return online.

Send a paper return 

If you need a paper copy of the main Self Assessment tax return you can: 

• download the SA100 tax return form 
• call HMRC and ask for the SA100 tax return form 

If you need to send a tax return for trustees of a registered pension, you must download form SA970. 

You can download all other forms and supplementary pages. 

After sending your paper return, you can check when to expect a reply from HMRC.
