Contact

We read every message about errors, broken tools and suggestions.

Email: contact@dollarfinch.com

Please include the page address and, for a tool problem, what you entered and what you expected. We usually reply within a few business days. We cannot file or amend a return, contact HMRC for you, or advise on your personal tax position — use GOV.UK, your Personal Tax Account, or a qualified adviser.

Advertising and partnership enquiries

Use the same address. We do not sell guide placements or accept sponsored posts that are not clearly labelled.
