Book a Free Trader ConsultationMarket trading comes with tax obligations that most generalist accountants are unfamiliar with. These are the rules that matter — and where mistakes are most costly.
All self-employed market traders must file an annual Self Assessment. Cash-based businesses face heightened HMRC scrutiny — accurate, verifiable records are essential. We handle the complete filing process and defend your return if challenged. Penalties for inaccurate returns can be significant, especially if HMRC deems the error careless or deliberate.
If you sell second-hand goods, antiques, vintage clothing, or collectibles, you may qualify for the VAT Margin Scheme — paying VAT only on your margin, not the total sale price. This can reduce your VAT bill by 30–40%. Most traders who qualify are not using it. We identify eligibility, implement the scheme, and correct prior overpayments where possible.
HMRC scrutinises cash businesses closely, particularly market traders. You must maintain daily cash records, receipts for all stock purchases, and clear records of opening and closing stock. We set up a simple, HMRC-compliant system that takes minutes per day to maintain — and satisfies the most rigorous HMRC enquiry.
From April 2026 (income over £50k) and April 2027 (income over £30k), digital record-keeping and quarterly submissions to HMRC are mandatory. Paper records and basic spreadsheets will not be sufficient. We migrate traders onto MTD-compatible software before the deadline — avoiding Day 1 penalties and HMRC correspondence.
HMRC actively investigates market traders, particularly those operating primarily in cash. Having clean, professionally maintained records is your best defence. If you receive an HMRC enquiry letter, we represent you — corresponding with HMRC on your behalf, attending any meetings, and protecting your position throughout the investigation process.
If your Self Assessment tax bill exceeds £1,000, HMRC requires you to make advance payments on account in January and July. Many traders are caught off-guard by this — facing a bill that's effectively 150% of what they expected. We plan for this from day one so you're never blindsided by a cash shortfall.
