Common questions

Asked andanswered.

  • Most single-job employees are taxed correctly through PAYE. But if you earn over £100,000, have untaxed income such as savings interest above your allowance, or need to claim certain reliefs, HMRC may require a Self Assessment. TaxGo checks your situation and lets you know.

Your tax return isn't going to do itself.

Actually, TaxGo gets pretty close.
