Running a UK limited company brings obligations a sole trader doesn't have: Corporation Tax (filed via CT600), Companies House annual accounts, and often payroll for yourself as a director. If you're a sole trader instead, our guide to AI tools for UK sole traders' Self Assessment covers that simpler setup — this post is specifically for limited companies. A quick honesty note, same as our last UK post: most of what's branded "AI" here is automation — receipt OCR, auto-categorisation, anomaly flagging — bolted onto established platforms, rather than something fundamentally new.

Are you actually affected by MTD yet? Qualifying income over £50,000: you're in now (since April 2026) £30,000–£50,000: you join from April 2027 £20,000–£30,000: ...
