Worth knowing
Rules that come up in this work
Confirmation statements and identity verification
Companies House has tightened its requirements under the Economic Crime and Corporate Transparency Act: every company needs a registered email address and an appropriate registered office, every statement includes a lawful-purpose declaration, and every director and PSC must verify their identity. The confirmation statement, due annually with a £50 fee, is where most of this is confirmed.
CIS deductions
Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.
The VAT registration threshold
VAT registration is compulsory once taxable turnover in any rolling twelve-month period exceeds £90,000, or when you expect to exceed that in the next thirty days alone. The test is rolling, not by tax year, and includes zero-rated sales. Businesses regularly cross it without noticing, and late registration means accounting for VAT on sales where it was never charged to customers.
Corporation Tax rates and marginal relief
Corporation Tax is not a flat rate. Profits to £50,000 pay 19%, profits above £250,000 pay 25%, and the band between is taxed at an effective marginal rate of 26.5% through the marginal relief mechanism. Associated companies share the thresholds, which catches directors who own more than one company and is the most common cause of underpaid tax in owner-managed groups.
Salary versus dividends
Directors of their own companies usually take a salary at or just above the National Insurance thresholds, which keeps the year qualifying for State Pension and is deductible for Corporation Tax, with further income as dividends. Dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% by band and can only be paid from distributable profits after tax, with a minute and voucher each time.
Director's loan accounts
Money taken from a company has to be something: salary, dividend, expense reimbursement or loan. If it is a loan and remains outstanding nine months after the year end, the company pays tax at the dividend higher rate on it until it is repaid. Clearing the balance with a properly declared dividend before the deadline, where reserves allow, is routine year-end work.
The Self Assessment calendar
The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.
Questions
CIS Tax Returns questions from City of London
What counts as construction work under CIS?
Site preparation, building, alteration, repair, decoration, demolition, and installing systems such as heating, lighting and water. Professional work such as architecture and surveying, scaffolding hire without labour, and carpet fitting are outside the scheme. Mixed contracts fall within it entirely. We check borderline cases against HMRC's list.
What records do I need to keep for CIS?
Subcontractors: every deduction statement, invoices and bank records. Contractors: verification references, gross payments, materials costs, deductions made and the statements issued, for at least three years. Missing deduction statements are the most common reason refunds are delayed, so we help you obtain copies from contractors.
What is gross payment status and can I get it?
Gross status means contractors pay you in full with no deduction; you pay your tax through Self Assessment or Corporation Tax instead. You need a construction turnover of at least £30,000 (sole trader) or £30,000 per director for companies, a clean compliance record for the previous 12 months and a UK bank account. Our £199 service prepares and submits the application.
How does CIS work for a limited company subcontractor?
Deductions suffered by a company are not reclaimed through Self Assessment. They are offset against the company's own PAYE and CIS liabilities each month through the Employer Payment Summary, and any excess at the year end is reclaimed from HMRC in writing. The £49 CIS plus payroll bundle handles this monthly.
How does the VAT reverse charge affect CIS work?
Since March 2021, where both parties are VAT and CIS registered and the supply is within the scheme, the subcontractor does not charge VAT; the contractor accounts for it on their own return. The invoice must state that the reverse charge applies. We check your sales and purchase invoices for this on every return.
Do I need to register for CIS?
Subcontractors should register so deductions are 20% rather than 30%; registration is free with HMRC or £49 through our service with your UTR sorted at the same time. Contractors must register before paying their first subcontractor. If you are both, both registrations are needed; our dual package is £99.
