Simplify Your HMRC Self Assessment Tax Return

Managing your UK tax obligations as a sole trader or self-employed professional doesn't have to be overwhelming. This HMRC Self Assessment Tax Return form template helps you organise all your income sources, expenses, and capital gains calculations in one clear, structured format—perfect for gathering information before submitting to HMRC or sharing with your accountant.

Whether you're a freelancer, consultant, contractor, or small business owner, this template guides you through every section of the self assessment process, from trading income and allowable expenses to capital gains and tax relief claims. Built with UK-specific requirements in mind, it ensures you capture all the details HMRC needs while keeping the process straightforward and manageable.

Built for UK sole traders and the self-employed

This form is designed specifically for sole traders, freelancers, and self-employed professionals navigating the UK tax system. It covers:

• Trading income from self-employment, including turnover and basis periods
• Allowable expenses across common categories like travel, equipment, office costs, and professional fees
• Capital gains calculations for asset disposals and reliefs
• Other income sources including property, dividends, interest, and employment income
• Tax relief claims for pensions, charitable donations, and marriage allowances

The template uses conditional logic to show relevant sections based on your answers, so you only see the questions that apply to your situation. This makes the form feel less intimidating and helps you complete your return more efficiently.

How Paperform makes tax preparation easier

With Paperform's calculation engine, you can add up expenses, apply allowances, and estimate tax liabilities in real time—giving you a clearer picture of your position before you submit. Conditional logic ensures you're only asked about income types and reliefs that are relevant to you, while the doc-style editor lets you customise the form with your own branding or additional guidance notes.

Once completed, submissions can automatically flow into Google Sheets, Airtable, or your accounting software via Paperform's native integrations, or you can trigger a workflow in Stepper to send the information to your accountant, generate a summary PDF, or set reminders for your January 31st payment deadline.

For accountants and bookkeepers managing multiple clients, Paperform's Agency+ plan lets you duplicate this form for each client, apply consistent branding, and manage submissions in one central dashboard—streamlining your practice and reducing the back-and-forth with clients during tax season.
