Frequently Ask Questions

Is Taxsub an accountant?

No. Taxsub helps you keep tidy records and understand your likely tax bill so you can avoid surprises and penalties. It doesn’t replace professional advice.

When are you launching?

We’re working on our first public beta now. Early access users will be invited in phases ahead of the Making Tax Digital changes.

Is my banking data safe?

Taxsub will use regulated Open Banking providers and industry-standard security. You’ll always stay in control of your data.

Will it file my tax return for me?

The first version focuses on tracking income, expenses and estimated tax. Full filing support will come later, potentially with partner accountants.

Join the early access list

We’re inviting a limited number of UK sole traders and self-employed people to try the first version of Taxsub. Join the list to get early access, help shape the app and lock in a discounted founder price.
