Late Tax Return Filing in Cardiff
If you have an overdue Self Assessment at a CF1 to CF24 address, daily late-filing penalties run at 10 pounds per day from 3 months overdue (capped at 900). As HMRC-registered accountants experienced with Cardiff cases, we file outstanding returns within days.
Cardiff late-filing cases concentrate around screen-sector freelancers (BBC Cymru Wales at Roath Lock, Wolf Studios Wales productions, Cardiff Bay independent shoots), HMO landlords serving the universities (Cathays, Roath, Plasnewydd), Welsh Government / Cardiff University staff with side income, and Welsh-language content creators with multi-platform income.

For Cardiff screen-sector freelancers (BBC Cymru Wales, S4C, ITV Cymru, Wolf Studios, independent productions) with one year overdue, the filing covers: PAYE shoot days from each production payroll (RTI captures these); self-employed prep / post / development work; loan-out company distributions if applicable; royalties or residual payments; allowable business expenses (camera kit, editing software, training, travel between productions, business proportion of home-office costs).
Cathays / Roath HMO Landlord Single-Year Filing
For Cathays / Roath / Plasnewydd HMO landlords with one year overdue, filing covers: gross rental income, allowable expenses (agent fees, repairs, insurance, mortgage interest at 20% credit only post-2020-21, Rent Smart Wales registration fee, Article 4 / additional licensing fees where applicable). Article 4 HMO planning constraints in central Cardiff affect council enforcement separately, not the SA filing itself.
