Self-Assessment Accountant in Windsor
Windsor is one of the most distinctive self-assessment markets in the London-Berkshire commuter belt, with the very substantial Windsor Castle and royal-tourism economy supporting a substantial self-employed events, hospitality, photography and wedding-services community, the substantial Eton community across the river with its associated independent-school and education catchment, high-earning employees commuting via South Western Railway into Waterloo (around 50 minutes), the substantial Royal Windsor Racecourse-related horseracing and events trade, and a substantial population of self-employed wedding planners, photographers, florists and bespoke-services providers serving the substantial Windsor wedding-destination economy. Many Windsor taxpayers fall into the self-assessment net for several reasons at once: self-employed events, hospitality or wedding-services income, PAYE plus substantial side-business income, the personal allowance taper for higher-earning professionals, and the high-income child-benefit charge.

📅 Get Your Free Self-Assessment ReviewReal Client Story
Client H is a self-employed wedding planner based in Windsor, running a high-end wedding planning business serving the Windsor, Cliveden and broader Home Counties wedding-destination market. Her annual income is around £88,000 across roughly 25 weddings per year, with substantial deposit-handling, supplier-payment and venue-coordination complexity. When they came to us, HMRC had opened a compliance check on her 2022/23 return six months after filing, questioning her cash-vs-accruals basis treatment of client deposits, her handling of supplier payments she had made on behalf of clients (passing-through costs), and her treatment of weddings booked in one tax year but actually held in the next. HMRC had requested extensive records and indicated a potential adjustment of around £18,000 of additional taxable income.
We took over the HMRC correspondence as her authorised agent within the week. We worked through her actual contracts and supplier invoices, classified each supplier payment as either pass-through (agent) or markup (principal) on its real legal nature, and built a complete reconciliation between her bank statements, deposit-tracking spreadsheet and the contracts. We then drafted a comprehensive response letter to HMRC documenting the correct treatment with supporting evidence: for pass-through payments we provided supplier invoices in the client's name showing she was merely facilitating payment; for markup payments we acknowledged the gross/net treatment and confirmed they were properly reported. For the cash-vs-accruals question, we documented that the cash basis (which she had been using and was eligible for given her turnover) was correctly applied throughout. We attended one in-person meeting with the HMRC inspector at our office to walk through specific examples.
Outcome: HMRC closed the compliance check with a small adjustment of around £1,400 (rather than the initial £18,000 they had indicated), no penalties applied because the original treatment was found to be defensible and honest, and ongoing forward, a documented record-keeping framework that distinguishes pass-through from markup payments and tracks deposits correctly so similar challenges will not arise in future. The client moved to our fixed monthly fee arrangement with full HMRC representation included, and going forward saves around £2,400 a year through proper expense capture that the previous DIY approach was missing.
