Worth knowing
Rules that come up in this 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.
Making Tax Digital for Income Tax
MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.
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.
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
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.
Director's loan accounts
A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.
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.
Questions
R&D Tax Credits questions from St. George's
How far back can I claim?
A claim can be made up to two years after the end of the accounting period, by amending the CT600. If you have two open periods both can be claimed. The notification rule applies to the later periods if you have not claimed recently, so the two-year window and the six-month window interact; we check both.
Does claiming R&D relief increase my chance of an enquiry?
HMRC now checks a far higher proportion of claims than before 2023, so any claim carries some risk of questions. A claim with a clear technical narrative, costs that reconcile to the accounts and payroll, and a named competent professional behind it is answered quickly. We write claims to that standard.
Can I claim for subcontracted work?
Under the merged scheme the company that decides to undertake the R&D and bears the risk generally claims, even if it subcontracts the work. Subcontractor costs are included at 65%. Overseas subcontractor and worker costs are largely excluded unless the conditions cannot be met in the UK. We apply the rules to your contracts.
What if HMRC opens an enquiry into an existing claim?
We review the claim, the narrative and the cost basis, tell you how robust it is, and quote a fixed fee for handling the enquiry before any work starts. Where a claim was overstated by a previous adviser, the best outcome is often an agreed reduction, and we say so rather than fight a losing position at your expense.
Why do you charge a fixed fee rather than a percentage?
Percentage fees reward inflating the claim, which is exactly what HMRC's campaign targets. A fixed fee means our only interest is a claim that is right. For most small company claims £999 is also considerably cheaper than the 15% to 30% of benefit that contingent advisers charge.
How long does a claim take to pay out?
HMRC aims to process 85% of claims within 40 days but the compliance campaign has lengthened this for many. Relief reducing a Corporation Tax bill takes effect when the return is processed; payable credits are paid to the company's bank account. We track the claim and chase HMRC if it stalls.
