Worth knowing
Rules that come up in this work
Confirmation statements and identity verification
The confirmation statement is the annual check that the public register is right: officers, registered office, SIC codes, shareholders and the PSC register. It carries a £50 fee and no financial penalty for lateness, but failure to file leads to compulsory strike-off. The identity verification regime introduced in November 2025 has added a further check to every statement.
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
Watching the rolling twelve-month turnover figure is one of the quiet jobs of monthly bookkeeping, because the £90,000 VAT threshold arrives silently. Crossing it brings quarterly returns, Making Tax Digital software and a decision about schemes. Crossing it late brings a bill for VAT you could not recover from customers and a penalty for failing to notify.
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.
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
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.
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
R&D Tax Credits questions from Putney Heath
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.
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.
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.
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 is the advance notification requirement?
Companies that have not claimed in the previous three accounting periods must notify HMRC of their intention to claim within six months of the end of the period. Miss it and the claim for that period is lost entirely. We check your position at the eligibility stage and file the notification as part of the service.
What is the Additional Information Form?
Since August 2023 every R&D claim must be accompanied by a form submitted to HMRC before the CT600, giving project descriptions, cost breakdowns, the named senior officer responsible and any agent involved. Claims without it are removed from the return. We complete and submit it as part of the £999 fee.
