Worth knowing

Rules that come up in this work

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.

Salary versus dividends

The salary-and-dividend split is the central planning decision for an owner-managed company. Salary costs employer National Insurance above £5,000 but is deductible; dividends are not deductible but attract lower personal rates and no National Insurance. The optimum changes each April with the thresholds and depends on the director's other income, so it should be set deliberately every year.

Corporation Tax rates and marginal relief

Companies pay Corporation Tax at 19% on profits up to £50,000 and 25% on profits over £250,000. Between those figures marginal relief applies, producing an effective rate that rises gradually and a marginal rate of 26.5% on each pound in the band. The thresholds are divided by the number of associated companies, so a director with two companies has thresholds of £25,000 and £125,000 for each.

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.

Making Tax Digital for Income Tax

Making Tax Digital for Income Tax began in April 2026 for sole traders and landlords with qualifying income over £50,000, extends to those over £30,000 in April 2027 and is planned for £20,000 in April 2028. It requires digital records in compatible software and four quarterly updates to HMRC each year, with a final declaration replacing the traditional return. Payment dates are unchanged.

Late filing penalties

HMRC's penalties for a late Self Assessment return are automatic: £100 the day after 31 January, £10 a day from three months late up to £900, then the greater of £300 or 5% of the tax at six and twelve months. Interest and separate late-payment penalties apply to the tax itself. Companies House charges £150 to £1,500 for late accounts, doubling for a second consecutive year.

Payments on account

A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.

Questions

CIS Tax Returns questions from Streatham Hill

How much CIS refund can I expect?

It depends on your profit and expenses. Deductions are 20% of the labour element of your invoices; tax is only due on profit after expenses and the £12,570 personal allowance, with Class 4 National Insurance on top. Many subcontractors earning under £35,000 get back several thousand pounds. We give you the figure before filing.

What does the £149 subcontractor return include?

Your full Self Assessment with the self-employment pages, every CIS deduction statement reconciled to your income, allowable expenses claimed, the refund calculated and the return filed. We then track the repayment with HMRC, which usually arrives within two to six weeks of filing in the quieter months.

What rate do I deduct from a subcontractor?

You must verify each new subcontractor with HMRC before the first payment. HMRC tells you 20% if they are registered, 30% if not, or 0% if they hold gross payment status. Deductions apply to the labour element only, never to materials, VAT or plant hire. We verify every new subcontractor and record the result.

When are contractor returns due?

The CIS300 monthly return covers the tax month to the 5th and must reach HMRC by the 19th. Deduction statements must go to subcontractors by the same date. A nil return is still required if you paid no subcontractors. Late returns cost £100 immediately, rising to £200 after two months and then percentage-based penalties.

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.

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.
