MTD for Income Tax goes live Monday (6 April). If you're a UK sole trader earning £50k+, you're affected.
The short version: you'll need MTD-compatible accounting software and quarterly digital submissions to HMRC from this week onwards. Annual self-assessment still exists but you also do quarterly updates now.
Most people are nowhere near ready. Common gaps:
FreeAgent is free if you have a NatWest, Starling, or Mettle business account, that's the quickest free path if you're scrambling.
I put together a comparison of 8 MTD platforms and a 30-day setup checklist at landolio.com if useful.
