Fill in the form correctly and make sure you’ve attached all relevant documents.
How do I submit it?
HMRC will fine you if your tax return isn’t submitted on time. If you haven’t filed your tax return within three months of April 5th, you could face penalties of up to £1000 per person. And if you’ve already missed the deadline, you’ll still have to pay interest on what you owe.
If you’re planning to file your tax return online, there are several options. You can use the self-assessment system, where you enter your information into the form yourself. Alternatively, you can download the e-filing app Taxback, which allows you to upload your returns directly. Or you can use the HMRC’s My Account feature, which lets you access your account information and make payments.
You can also choose to file your tax return via post. In this case, you simply send off your completed form to HMRC. However, you’ll need to attach a list of supporting documents, including invoices, receipts and bank statements.
The SA100 is one of two forms that HMRC requires to be sent along with your tax return. The other form, called the SA500, covers the income side of the tax return, while the SA200 covers the capital gains and losses.
There are two ways to submit your SA100. One way is to print out the form, fill it out and sign it. Then take it to a Post Office branch or drop it in the mail. The second option is to scan the form and email it to HMRC. Both methods are valid, although sending it by post might mean you miss out on some of the benefits offered by online filing.

Frequently Asked Questions
How can I submit my Self Assessment tax return using the SA100 form?
The ‘SA100’ is the self assessment tax form that most people fill out each year. You’ll find it on your tax code, along with instructions on how to complete it. If you’re filing for the first time, you’ll probably receive a copy of the form in the post. If you’ve already filed for the previous year, you won’t get another copy unless there are changes to your tax situation.

When must I submit an SA100 form and is it best done online or by post?
As mentioned above, we recommend that you file your tax return via e-filing. However, there are still people out there who prefer to use the paper version. So here is our breakdown of when you need to file your SA100 returns:
– If you’re a sole trader or partnership, you’ll need to file your return within 4 months of the end of the financial year.
– If you’re employed, you’ll need to complete your tax return within 5 months of the end of your pay period.
– If you work part-time, you’ll need to provide proof of your employment status to HMRC. This could mean providing evidence of earnings or paying income tax.
– If you earn less than £5,500 per annum, you won’t need to complete your tax returns.
– If you earned over £50,000 during the tax year, you’ll need to fill in the form and submit it within 10 working days of receiving your W8A form from HMRC.
