Self-Assessment Accountant in Stevenage
Stevenage is one of the most distinctive self-assessment markets in the broader London-Hertfordshire commuter belt, with the very substantial Stevenage aerospace and defence cluster (MBDA, Airbus Defence and Space, Stevenage Bioscience Catalyst), the substantial GSK research and development site supporting the wider Stevenage life-sciences community, a substantial mix of self-employed aerospace engineers, scientists, pharma consultants and tech-sector contractors serving the surrounding corporate cluster, high-earning employees commuting via Great Northern services into King's Cross (around 25-30 minutes), and a substantial population of self-employed tradespeople and small-business owners across SG1 and SG2. Many Stevenage taxpayers fall into the self-assessment net for several reasons at once: self-employed engineering or scientific consultancy income, PAYE plus substantial side-consulting income (very common among Stevenage tech-sector employees), and the personal allowance taper for higher-earning professionals.

📅 Get Your Free Self-Assessment ReviewReal Client Story
Client M is a self-employed aerospace systems engineer based in Stevenage, working contract assignments with UK defence contractors and European aerospace primes. Recent project work had taken him to France, Italy and Germany for extended on-site periods, generating around £158,000 of self-employed engineering consultancy income with substantial overseas-travel, accommodation and subsistence costs. When they came to us, HMRC had opened a compliance check on his 2022/23 return questioning whether the residence-test position he had claimed was correct (he had been treating roughly 40 per cent of the year overseas as 'overseas workdays' eligible for some form of exemption), and whether the full extent of his expense claims for overseas accommodation and subsistence were genuinely business-only.
We took over the HMRC correspondence as his authorised agent and immediately requested a 30-day extension to provide a comprehensive response. We then worked through his actual day-count record, calendar entries, flight bookings, and on-site project documentation to build a detailed Statutory Residence Test analysis for the tax year in question. The analysis confirmed that he was genuinely UK tax resident under the SRT (he had a UK home, UK family ties, and UK work base in Stevenage; the overseas work was project-specific, not relocation), which meant his worldwide income was correctly subject to UK tax. The 'overseas workday relief' he had been claiming was not actually available to him as a UK-domiciled UK resident, but he had simply been claiming legitimate UK-resident tax treatment with foreign-tax credit for any foreign tax suffered, which was correct. The expense claims were similarly defensible: project travel and accommodation were properly business expenses incurred wholly and exclusively for business purposes. We drafted a detailed response letter with full evidence and a clear technical analysis.
Outcome: HMRC closed the compliance check with no adjustments, no penalties, and a written acknowledgement that his position was correctly stated. Going forward, we put a robust residence-test record-keeping framework in place (day count tracker, project documentation, contemporaneous-evidence requirements for travel and accommodation) so future enquiries can be defended quickly, and ongoing tax saving of around £3,200 a year through proper expense capture and pension contribution timing that the previous DIY approach was missing.
