Worth knowing
Rules that come up in this work
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.
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.
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.
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.
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 trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Employer National Insurance
The cost of an employee is more than the salary. Employer National Insurance at 15% above £5,000 a year, the 3% minimum pension contribution, holiday pay, equipment and management time all come on top. The Employment Allowance of £10,500 reduces the National Insurance for most employers with more than one person on the payroll.
Questions
R&D Tax Credits questions from West Croydon
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.
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.
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.
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 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.
Which deadlines matter most for r&d tax credits?
The next four dates that apply to r&d tax credits are shown at the top of this page, calculated from today. For West Croydon clients we diarise every one of them from the day you join and send reminders before each, so the work is done in good time rather than in the last week before a penalty.
