Dartford sits at the centre of one of the busiest construction corridors in the South East. Ebbsfleet Garden City is delivering up to 15,000 homes a few minutes down the A2, the Lower Thames Crossing has moved from planning into one of the largest civil engineering mobilisations in a generation, The Bridge and the town centre regeneration keep local trades busy, and the M25/A2 junction makes Dartford a natural base for subcontractors working across Kent and into London every week. The Construction Industry Scheme is the single most common reason those subcontractors overpay tax. Main contractors deduct 20 per cent from every payment, or 30 per cent if you are not verified, regardless of your real costs. For a Dartford subbie running a van across the QE2 Bridge or down the A2 every day, those real costs are substantial, and by April the deductions have usually overshot your true tax bill by a wide margin. A properly prepared Self-Assessment typically unlocks a refund of £1,500 to £5,500.
The Dartford pattern we see most is the commuting subcontractor: living in DA1 or DA2, working sites in Ebbsfleet one month, Canary Wharf or the City the next, with thousands of business miles, Dart Charge crossings and parking that never make it onto a tax return. Your Tax Help Accountants, HMRC-registered, handles every aspect of CIS for Dartford trades fully online: same-day refund filing from 6 April with every mile and every receipt captured, monthly CIS300 contractor returns for those engaging subbies on local jobs, verification before first payment so you never sit on the 30 per cent rate, and gross payment status applications for established trades. Fixed monthly fees, no per-return charges.

Behind on Self-Assessment or CIS returns? We bring you up to date and engage with HMRC about penalties, requesting reductions where there's a reasonable excuse.
You can claim CIS refunds for up to four prior tax years. Many Dartford subcontractors are owed several thousand pounds across multiple years, usually because mileage to London sites was never claimed. Book a free call and we will scope it out.
📅 Get Your Free Backdated CIS ReviewReal Client Story
Client D is a steel fixer from Dartford who spent the year split between an Ebbsfleet residential phase and two frame jobs in East London. He came to us in March having never claimed mileage in six years of self-employment, convinced his refund would be "a few hundred quid like last time". His previous filings listed CIS deductions and almost nothing else.
We rebuilt his year properly: 14,000 business miles between DA1, Ebbsfleet and the London sites, Dart Charge crossings and site parking, his own tools and consumables, PPE and boots, CSCS renewal and a working-at-height refresher, phone, and the public liability policy he had been paying personally. We then reviewed the previous tax year too, amended it, and moved him onto a receipt-capture app.
Outcome: £4,900 refund for the current year filed within 48 hours of 6 April, plus £1,750 recovered from the amended prior year. Total back in his account: £6,650, against six years of "a few hundred quid".
