Worth knowing
Rules that come up in this work
Closing a company
Voluntary strike-off is available only to solvent companies. One that owes money it cannot pay needs a creditors' voluntary liquidation through a licensed insolvency practitioner, and directors who dissolve an insolvent company face personal consequences. For a solvent company the process takes three to four months from filing the DS01, with notice to creditors and shareholders within seven days.
Switching accountants
You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
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.
The trading and property allowances
Not every small income needs a tax return. The trading allowance exempts the first £1,000 of self-employment or casual income and the property allowance does the same for rental income, each measured on gross receipts. They cannot be combined with rent-a-room relief on the same income, and claiming the allowance means giving up the expense deduction for that source.
Dormant companies
Companies formed to protect a name or hold a future business are dormant but not exempt: Companies House still expects dormant accounts within nine months of the year end and a confirmation statement annually with its £50 fee, and HMRC must be told the company is dormant or it will demand Corporation Tax returns. The filings are short, but the penalties for missing them are the same as for a trading company.
The 60-day property CGT return
Selling UK residential property that was not your main home for the whole period of ownership triggers a separate Capital Gains Tax return, due within 60 days of completion along with payment of the tax. This is in addition to the annual Self Assessment. The gain is taxed at 18% or 24% depending on your income band, after the £3,000 annual exempt amount.
Questions
R&D Tax Credits questions from Wallington South
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.
What costs qualify?
Staff costs including employer NI and pension for time spent on R&D, externally provided workers at 65%, subcontracted R&D at 65% with new rules on who claims, software licences, cloud computing and data costs, consumables transformed or used up in the R&D, and some clinical trial payments. Capital spend, rent and marketing do not qualify.
How much is the relief worth under the merged scheme?
For accounting periods starting on or after 1 April 2024 the merged scheme gives a 20% expenditure credit, taxable, so worth around 15% to 16.2% of qualifying spend net of tax. Loss-making companies spending at least 30% of total expenditure on R&D can claim the enhanced intensive rate, worth up to 27%.
What counts as R&D for tax purposes?
A project seeking an advance in overall knowledge or capability in a field of science or technology, through the resolution of scientific or technological uncertainty that a competent professional in the field could not readily resolve. Commercial novelty is not enough; routine development with known methods is not enough. The test is about the technology, not the product.
Why is the eligibility review free?
Because a large share of enquiries do not qualify, and we would rather tell you that for nothing than charge £999 for a claim HMRC rejects. The review takes a short call and some questions about the projects. You get a written view: qualifies, does not qualify, or borderline with the reasons. There is no obligation afterwards.
