CIS, the VAT reverse charge, gross payment status, Making Tax Digital and payroll for Sheffield trade businesses. We only act for trades, and we work with you remotely.
The short version. Sheffield is in England, so the Building Safety Levy applies here from 1 October 2026, though developments of fewer than 10 units are exempt, and the dutyholder and competence duties in SI 2023/911 apply to all building work. Everything on the tax side is UK-wide: CIS at 20% and 30% with the return due by the 19th and payment by the 22nd, the VAT domestic reverse charge, VAT registration at £90,000, Making Tax Digital, employer NIC at 15% above £5,000, and the £1,000,000 annual investment allowance. Building control for your work here sits with Sheffield City Council.
Registering someone for CIS, verifying them with HMRC and deducting 20% does nothing whatsoever to establish that they are self-employed. CIS 340 says so directly: for a contract to be within the scheme it must not be a contract of employment, which means the scheme assumes self-employment rather than creating it. Employment status is decided by common law principles, and HMRC's guidance puts the duty to consider it on the contractor at the point of first engagement — adding that the fact someone has worked self-employed before is irrelevant, because it is the terms of the particular engagement that matter.
gov.uk's markers of self-employment are bidding or quoting for work, working without direct supervision, invoicing for work done, being responsible for your own tax and NIC, having no holiday or sick pay, and a contract described as self-employed or independent. Read those against a typical labour-only engagement — all materials and plant supplied, set hours under direction, one site, one contractor, no right of substitution, no financial risk — and almost none of them are present.
The exposure sits with the contractor. On a worker paid £40,000 a year, employer National Insurance at 15% on earnings above the £5,000 secondary threshold is £5,250 that was never budgeted, before any question of the PAYE and employee NIC that should have been withheld, or interest and penalties. A 20% CIS deduction, by contrast, costs the contractor nothing at all — it is withheld from the worker. Across four such workers over three years, employer NIC alone is in the region of £63,000.
Two rules to keep straight. Where an agency supplies workers under a contract to carry out construction operations, the agency is a subcontractor and CIS applies to your payments to it; where the agency merely introduces workers, it is not a subcontractor and CIS does not apply. And where the off-payroll working rules apply, the payment to the agency is not a contract payment and CIS should not be operated on it — off-payroll and CIS are mutually exclusive on the same payment.
The same work whichever trade you are in, because the problems are the scheme's rather than the trade's. We run the monthly CIS return and verification cycle, apply for and protect gross payment status, get the reverse charge right on your invoices and get end user notifications on file, put your records on software that satisfies Making Tax Digital, run payroll with the CIS offset claimed monthly through the employer payment summary, and prepare the accounts and tax return.
Two things we do that a general accountant usually does not. We reconcile your CIS suffered to the payment and deduction statements every month rather than once a year, which is where under-claimed materials and missing statements turn up — see the records guide. And we treat your VAT compliance as part of your CIS position, because since 6 April 2024 it literally is: VAT joined CIS, PAYE, income tax and corporation tax in the gross payment status compliance test.
We write for each trade separately, because the scope questions differ. An electrician is inside CIS on power, lighting and fire protection and outside it on burglar alarms and CCTV. A steel fabricator is outside the scheme on manufacture and delivery to site and inside it on erection. A scaffolder is inside CIS, and separately hired scaffolding is standard rated for VAT even on a zero-rated new build. There are pages for plumbers, roofers, groundworkers, joiners, bricklayers, plasterers and every other trade we act for.
Three free calculators, no email required: the CIS deduction calculator shows what materials do to a deduction, the gross payment status checker tests you against all three statutory tests, and the reverse charge checker works through the six conditions on a specific job.
No. CIS 340 states that for a contract to be within the scheme it must not be a contract of employment, which means the scheme assumes self-employment rather than establishing it. Registering a worker, verifying them and deducting 20% has no bearing on their employment status, which is determined by common law principles. HMRC's guidance is explicit that it is for the contractor to consider status when the subcontractor is first engaged, and that the fact someone has previously worked self-employed is irrelevant because the terms of the particular engagement are what matter. A CIS deduction is a tax mechanism, not a legal determination.
Mostly employer's National Insurance, plus interest and penalties. The worker has usually already paid income tax and Class 4 NIC through Self Assessment, so the irrecoverable element is the employer NIC at 15% on earnings above the £5,000 secondary threshold — around £5,250 on a worker paid £40,000 a year — together with the difference in how the rest should have been collected. Note the contrast with CIS: a 20% deduction costs the contractor nothing because it is withheld from the worker, whereas employer NIC is a genuine additional cost. Four such workers over three years puts the employer NIC exposure alone near £63,000.
Less than most trades expect, and not the things they expect. Sheffield is in England, and the Construction Industry Scheme is UK-wide: 20% standard rate, 30% higher rate, the monthly return due by the 19th and the money by the 22nd. The VAT domestic reverse charge, the £90,000 registration threshold, Making Tax Digital, National Insurance, corporation tax and the £1,000,000 annual investment allowance are identical too. What changes is building safety — the Building Safety Levy applies here from 1 October 2026, though developments of fewer than 10 units are exempt, and the dutyholder and competence duties in SI 2023/911 apply to all building work — and the income tax on your profit, which is the UK rates — 20%, 40% and 45%, with the higher rate starting at £50,270 on a full personal allowance.
No. We act for trade businesses in Sheffield and across the UK remotely — phone, WhatsApp, video and email, with records and approvals handled online. That is deliberate rather than a limitation, because what decides a trade's tax position is not local knowledge but knowing the scheme: whether the work is a construction operation within CIS, whether the payment is CIS-reportable, whether your customer has notified end user status in writing, whether the materials figure on your invoice will stand up, and whether you should have gross payment status. None of that is answered by being twenty minutes down the road. What being in England does change is building safety and, on income tax, uk bands: 20% / 40% / 45% — and we take that into account without needing an office here. The calculators on this site are free and need no conversation at all.
