MTD Deadlines for Cardiff Businesses
From 6 April 2026, Cardiff sole traders and landlords with qualifying income over £50,000 will be legally required to submit quarterly digital tax updates to HMRC, using approved MTD software, with proper digital record-keeping, or face immediate penalties. The threshold drops to £30,000 in April 2027 and £20,000 in April 2028, bringing the vast majority of Cardiff's self-employed people into MTD scope.

Cardiff Bay Media Contractor Saved £7,200/Year
A freelance video editor based in Cardiff Bay (CF10) came to us in early 2026, earning approximately £78,000/year across multiple BBC Wales, S4C, and independent production company contracts. She was running her own PSC (limited company) but had never had proper tax planning.
Her Challenges
- PSC set up but MTD VAT never properly configured
- Taking £8,632 salary + £42k dividends (below optimal)
- Professional equipment (cameras, editing suites, software) claimed inconsistently
- Home office in Cardiff Bay apartment claimed at flat rate
- No pension contributions despite Corporation Tax relief available
- IR35 status of BBC work never formally assessed
What We Did
- Formal IR35 assessment on all current contracts (mixed: some inside, some outside)
- Set up Xero (£33/mo) with MTD VAT configuration
- Restructured salary to £12,570 + £38k dividends
- Set up £25k employer pension contribution (£4,750/yr Corporation Tax saving)
- Switched home office to actual costs (£1,200/yr saving)
- Identified £3,400/yr in overlooked professional development and equipment expenses
- Took over quarterly MTD VAT + Corporation Tax planning for £180/month
Outcome: Full MTD VAT compliance plus £7,200/year in tax savings. Net cost of our service £2,160/yr; net benefit £5,040/yr. Plus proper IR35 documentation ready if HMRC ever challenges her BBC contracts.
