Self Assessment Done in 5 Minutes
We take care of calculating your tax, managing your expenses, and filing your Self Assessment — so you can focus on running your business.
Built for Sole Traders
We know what it’s like: juggling jobs, invoices, expenses, and tax deadlines. QTax is built specifically for sole traders — gardeners, creatives, tutors, tradespeople — to make Self Assessment straightforward and stress-free.
Our team has supported thousands of sole traders over the years, and we’ve used that experience to design a product that meets your real-world needs. QTax is fully compatible with Making Tax Digital (MTD) requirements, so you stay compliant as regulations continue to change.

All the tools a sole trader needs, with security and compliance baked in.

Expert Accounting Meets Smart Automation
QTax isn’t just a tool — it’s built by senior certified accountants. We’ve layered in intelligent automation to save you time: your data is organised and checked automatically, and helpful prompts ensure you don’t miss anything important.
Smart guidance
Automated checks flag common pitfalls and remind you about eligible expenses — like having an expert looking over your shoulder, without the jargon.
Fair, Transparent Pricing
You don’t need to hire a full-time accountant to file your tax return accurately. QTax offers a cost-efficient way to complete your Self Assessment — with no surprise fees or unnecessary extras.
Value without surprises
Simple, fair pricing with optional protection if HMRC selects you for a compliance check.
How It Works
QTax guides you through each step with clear explanations along the way.
