What this toolkit is for

HMRC's own guidance is authoritative, but most people still end up hopping between eligibility pages, deadline explainers, and blog posts to get a straight answer. The MTD Toolkit is the cleaner public layer around those questions.

It is designed to be free, fast, no-signup, and deep-linkable. You can send someone straight to the scope check, the deadline tracker, the cumulative reporting walkthrough, the FAQs, or the categories explainer without making them start over.

Inside the toolkit
