If you’ve received income from a trust, settlement, or the estate of someone who has passed away, you’ll likely need to report it using the SA107 form.

What is the SA107 form?

The SA107 is a supplementary form to the main SA100 Self Assessment. It’s used to declare income from trusts, settlements, or estates as part of your tax return, whether you file with HMRC’s online service or through an accountant. This type of income is closely monitored by HMRC, as under-reporting can result in severe penalties. Transparency is key—ensure all relevant income is properly declared. Failure to do this can lead to severe penalties.

Here's what the SA107 form looks like so you can be sure you're using the correct form:

Let’s find out what it is and how to use it, so you can stay fully tax compliant.  

Do I need to file an SA107?

You need to file an SA107 (or provide the same information for the same declarations if you file your tax return online )for any of the following forms of income: 

• Beneficiary of a trust/settlement - Filing required if you received or were entitled to income, excluding income from bare trusts.

• Settlor contributions - Necessary if you've contributed money or assets to a trust or settlement.

• Income from deceased estates - Required if you've received income from an estate of someone who has passed away.

• Income from settlor-interested trusts -  Applicable if you're taxable on income arising to trustees where you, as a settlor, have an interest.

• Income to minor children - Essential if your minor children receive income from property you've placed in settlement, and you're taxable on this income.

How to file an SA107 form

If you file your Self Assessment via paper form, then you can download the and print the SA107 here. 

If you file your Self Assessment online you don’t need a SA107 form, you will find a dedicated section for reporting this type of income when you complete your online tax return. 

However, currently it’s not possible to do this using HMRC’s online service - you have to use approved third-party accounting software to attach an SA107 to your tax return online. We would highly recommend this method as you get an extended filing deadline and it is much quicker and easier.

The easiest way to understand how to use the SA107 form is if we split the process into two parts, with instructions for both completing and submitting/filing the form.

Filling in the SA107 form

The paper form is 2 pages long and consists of 5 main sections, divided into different sub-sections. You can view, read and download the form from HMRC's webpage. There are also a number of ‘help-sheets’ available as well.

Completing the form itself is quite straightforward; answer each question of the 24 boxes (boxes 20 & 21 are not in use). However, understanding the terminology of the form can be quite confusing, so it’s essential to read the ‘Trust ect’ notes to enable you to answer the relevant questions correctly. 

For example, if you’re a beneficiary of a trust declaring trust income you may need to refer to the form ‘R185 (Trust Income)’, a form a trustee used to inform you about your income payments or entitlement from the trust.

Make sure you don’t confuse this version of the R185 with the R185 (Settlor) form which trustees use to tell settlors, ‘’about income arising from a trust in which they retain an interest.’’ You may also need to know whether you are a ‘’settlor chargeable on the income arising or paid to another person.’’ 

The easy way to make sure your SA107 form is completed correctly
