Built for sole traders

Sign up, connect securely to HMRC, share your income and expenses, and submit with confidence. QTax keeps the path clear and jargon-free.

Fully compatible with Making Tax Digital (MTD) requirements, so you stay compliant as regulations evolve.

A clear, guided flow from sign-up to submission

We guide you through each step with plain-English prompts, smart checks, and an easy review before you file.

1. Sign in and Connect to HMRC

When you first sign up, you'll securely connect QTax to HMRC using your Government Gateway login. We import any available information so you’re not starting from scratch.

2. Share Your Income and Expenses

You’ll answer simple questions to help us understand your business. We guide you through income, costs and allowable expenses in plain English — whether you’re a tradesperson, freelancer, tutor or gardener.

3. Smart Guidance and Checks

As you input your information, QTax flags common pitfalls, highlights potential mistakes and reminds you about eligible expenses. It’s like having an expert looking over your shoulder — without the jargon.

4. Review Your Draft Return

You’ll receive a clear summary of your tax position: total income, expenses, and your estimated liability. If something looks off, you can adjust it before submission.

5. Submit Directly to HMRC

When you’re ready, submit your Self Assessment through QTax. We handle the secure transmission and confirm once HMRC receives it — with a copy stored for your records.
