Completing a self-assessment tax return can seem daunting, especially if you’re doing it for the first time. However, with an understanding of the process and a systematic approach, it’s more straightforward than you might think. This article guides you through the steps of completing your self-assessment tax return accurately and efficiently.

Step 1: Register for Self-Assessment

If you’re new to self-assessment, you need to register with HM Revenue and Customs (HMRC). You can do this online through the HMRC website. Once registered, HMRC will send you a Unique Taxpayer Reference (UTR) and set up your account for the Self-Assessment online service.

Step 2: Gather Your Information

Before you start filling out your tax return, gather all the necessary information. This includes details of your income from all sources, such as employment, self-employment, rental income, and any dividends or interest from savings and investments.

You’ll also need details of any allowable expenses or reliefs you want to claim, and details of any pension contributions you’ve made. If you have other income, such as from renting out a property, you’ll need these details too.

Step 3: Log In and Fill Out Your Tax Return

Log in to your HMRC online account to start your tax return. The form is divided into sections – you only need to fill out the sections relevant to you.

In the ‘tailor your return’ section, check the boxes that apply to you. You’ll then only see the sections you need to fill out. If your circumstances change, you can go back and change your answers.

Step 4: Report Your Income and Expenses

Enter your income from all sources in the relevant sections. If you’re self-employed, you’ll need to fill out the ‘Self-employment‘ pages, and if you have rental income, you’ll need to complete the ‘Property’ pages.

Don’t forget to claim any allowable expenses. If you’re self-employed, this might include costs like travel, office expenses, or costs of goods sold.

Step 5: Check Your Calculation

Once you’ve entered all your information, you can view your calculation. This shows how much tax you owe based on the information you’ve provided. Check this carefully to make sure it looks correct.

Step 6: Submit Your Tax Return

Once you’re happy with your tax return, you can submit it online. You’ll get a confirmation message to say it’s been received, and you’ll be able to view your completed return in your account.

Step 7: Pay Your Tax

The final step is to pay any tax you owe. This can also be done online, and must be done by midnight on 31st January.

Remember, completing your self-assessment tax return accurately and on time is crucial to avoid any penalties. Start early, gather all your documents, and take it step by step. If you’re unsure about anything, don’t hesitate to seek professional advice. Tax can be complicated, but with the right approach, you can handle it with confidence.
