Worth knowing
Rules that come up in this work
Employer National Insurance
Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.
Allowable expenses
An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do not.
Record keeping
Good records are the difference between a quick enquiry and a long one. For the self-employed, five years after the filing deadline; for companies, six years from the year end; for VAT, six years. Photographs of receipts, PDF statements and software exports all count. The requirement is to keep records, not paper, and a well-organised cloud folder satisfies it.
The 60-day property CGT return
Since April 2020 a gain on UK residential property must be reported and the tax paid within 60 days of completion through HMRC's dedicated service, separately from the annual return. Non-residents must report all UK land disposals in the same window whether or not tax is due. Getting the computation right first time matters because the figure is then carried into the Self Assessment.
Crypto records and reporting
Most crypto holders have taxable events they do not recognise, because every swap is a disposal even when no pounds change hands. The computation requires the complete transaction history from every exchange and wallet, pooled by asset with HMRC's matching rules applied. Exchange-generated tax reports are frequently wrong because they cannot see transfers between a user's own wallets.
CIS deductions
CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.
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.
Questions
R&D Tax Credits questions from Soho
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.
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.
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.
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.
Is r&d tax credits in Soho really the same price as elsewhere?
Yes. The fee published on this page is what a client in Soho, Westminster pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
Do you have an office in Soho?
No. IGI Accounting is an online-only firm. We serve Soho, Westminster and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for r&d tax credits is the same in Soho as anywhere else in the country, and why there is nothing to visit and nothing to print.
