Northern Ireland's tech cluster — Belfast's cybersecurity + fintech contractors and the MTD ITSA gap. From 6 April 2026 every Belfast 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.

Belfast has the UK's densest cybersecurity cluster outside London — CSIT, Cyphra, Whitehat, Rapid7 — supplying contractor-grade specialists across financial services and government. The Titanic Quarter creative hub anchors film/TV freelancers (Game of Thrones legacy, Northern Ireland Screen productions), Spirit AeroSystems remains a major aerospace employer with a sole-trader supply chain, and Belfast's post-2018 property market has produced an active landlord base. NI-specific tax rules (e.g. NI Customs Declaration Service for goods movement) add complexity for some sole traders. The MTD ITSA SERP in Belfast is genuinely empty — no incumbent ranks for the city plus the topic.
Same prices wherever you are in the UK — no premium for Belfast 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. Belfast-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.
You pay UK Income Tax (HMRC), not Irish. Belfast residents are UK tax residents regardless of where their clients are based. The cross-border invoice may have Irish VAT treatment to think about (VAT MOSS for digital services etc.) but the Income Tax side is straightforward UK MTD ITSA. We handle the cross-border VAT classification at setup.
No. The NI Protocol covers goods movements and VAT for goods, not personal Income Tax. MTD ITSA quarterly submissions for NI sole traders follow the same rules as the rest of the UK. Where it affects you is if you also move physical goods between NI and GB — that's a separate VAT/customs question we route to a specialist.
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 Belfast 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 Belfast accountants haven't filled.
