How to claim your SEIS income tax relief

Congrats! You've invested in a company and now you also want to ease your tax burden.

While SEIS gives incredible tax reliefs, you need to claim them in order to benefit from them. These are the key things you need to know about the process.

Things you need to have

  • Company names that you invested into
  • Date on which the shares were issued to your name
  • Amounts you invested in each company
  • HMRC office that authorised the issue of the SEIS 3 certificate

Where you can get this information

1. Your SEIS3 certificate

After the company you invested in has been trading for 4 months or when they've spent 70% of the invested money, they can request the SEIS3 certificates from HMRC for their investors. Once they've received them they send them out to their investors.

If you used an agency or an investment platform to invest in the company you should receive SEIS3 certificate from them.

The SEIS3 certificate contains the key information needed for claiming your tax relief with your self assessment: including the time and amount of investment and crucially until what date (3 years from investment) you need to keep the shares to be eligible for Capital Gains Tax exemption if you wish to sell your shares.

2. Your Share Certificate

The companye you invested in must have also issued you a share certificate. This is the document that proves you're a shareholder in the business. In many ways it contains the same information as your SEIS3 certificate, minus the specifics about the SEIS.

Things you need to do

1. File your annual income tax return

When you're filing your annual income tax return you must claim the SEIS income tax relief by filling in the "other tax reliefs" section on your Additional Information (SA101) page at HMRC.

You'll need the enter the total amount invested into companies under SEIS

At the bottom of the page you'll need to provide the information listed at the top of this article at the additional information section

Alternatively, of course, you can use TaxScouts and this is all done for you.

The exact amount of relief will depend on your investment and income tax situation but generally it is 50% of the amount you invested. You can read more about it in our "What is SEIS" section.
