Solas - Sole Traders Tax

Let AI do your books. Solas categorises every transaction, tracks your tax in real time, and files your Self Assessment for you. Free forever.

Making Tax Digital is here. From April 2026, HMRC requires sole traders earning over £50,000 to file quarterly digital tax updates. That means four times the paperwork, four times the deadlines, and a whole new compliance burden.

Solas handles all of it for you.

AI-powered transaction categorisation • Real-time tax calculations • Receipt scanning and matching • HMRC-ready quarterly and annual submissions • VAT returns • Professional invoicing with online payment collection • AI tax assistant chats • Mileage logging for business travel • Full double-entry bookkeeping under the hood

Coming soon: • Open banking bank feeds. Transactions imported automatically from your bank

Upgrade to Solas Premium for £20/month or £200/year:

• Unlimited AI tax assistant chats • Human reviewer for your year-end submission • No Solas fees in invoice payments • Multi-vehicle milage logging • More intelligent tax deductions • Priority support

Solas is built specifically for UK sole traders. Not a stripped-down version of software designed for accountants or limited companies. Every screen, every feature, every calculation is designed around how self-employed people actually work.

Your data stays in the UK and EU. Solas is registered with the ICO and recognised by HMRC as MTD-compatible software. Stop doing your tax. Let Solas handle it.
