Worth knowing
Rules that come up in this work
The VAT registration threshold
The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.
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
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.
Director's loan accounts
The most common tax problem in owner-managed companies is an overdrawn director's loan account: drawings taken during the year that were never declared as dividends or salary. The company faces a 35.75% charge on the balance outstanding nine months after the year end, and the director may have a benefit in kind. We review the account before every year end to clear it properly.
The Self Assessment calendar
Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.
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.
Late filing penalties
Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.
Questions
CIS Tax Returns questions from Sipson
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.
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.
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.
