UK's largest cruise + container port — marine pilots, surveyors, and offshore consultants in scope April 2026. From 6 April 2026 every Southampton sole trader and landlord earning £50,000+ must submit quarterly to HMRC. We do all of it — setup, software, quarterly filings, year-end. £495 one-time + £150/mo.
CGMA-qualified · 24 years professional finance · Single named accountant
Southampton's sole-trader economy is shaped by the port: marine pilots (Solent VTS-licensed), marine surveyors, ship-agency consultants, customs and freight specialists. Add ABP services contractors, B&P Marine subcontractors, and a substantial cruise-supply freelancer pool (Carnival UK is HQed here). The University of Southampton drives life-sciences and engineering spin-out consultancy, and PO1–SO15 landlord activity is steady. The MTD ITSA SERP for Southampton has no clear incumbent — a credible maritime-aware service can position fast.
Same prices wherever you are in the UK — no premium for Southampton sole traders.
We configure everything. You file the submissions yourself.

6 April 2026 if your qualifying income exceeds £50,000. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028. Southampton-based sole traders and landlords are caught identically to the rest of the UK — HMRC applies the same rules.
All four quarterly submissions, the year-end Final Declaration (with year-end adjustments rolled into it), monthly bookkeeping (up to 200 transactions/month), one VAT return per quarter if applicable, and email/Slack support with one-business-day response. Single CGMA-qualified accountant handles your account end-to-end.
Pilotage authority disbursements paid to you as a self-employed pilot are self-employment income on your MTD ITSA quarterly submission. The authority typically issues statements monthly — these become your primary income evidence. We map the statement format into your bookkeeping software at onboarding so each quarterly cut-off captures the right monthly statements without manual juggling.
You report MTD ITSA income in GBP. Multi-currency invoices convert at the date the income is recognised (cash basis = receipt date; accruals = invoice date). HMRC accepts published FX rates or your bank's actual conversion rate consistently applied. We set the FX rule at setup so quarterly submissions are predictable rather than re-debated each period.
MTD ITSA is administered nationally — your physical accountant location doesn't affect the submission process. BlackpeakCFO is 100% remote, ACMA-CGMA-qualified, and gives every Southampton client the same single-named-professional accountability you'd get from a London boutique at £400+/mo. The £150/mo Plus tier is the gap most Southampton accountants haven't filled.
