Worth knowing

Rules that come up in this work

Allowable expenses

Expense claims are where a return is won or lost in an enquiry. The test is wholly and exclusively for the trade; where a cost is mixed, the business proportion can be claimed if it can be identified. Capital items such as equipment and vans are relieved through capital allowances rather than as expenses, except under the cash basis where they are simply deducted when paid.

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

The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.

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 trading and property allowances

Small side incomes are covered by two £1,000 allowances, one for trading and one for property, which remove the need to register or report income below that level. Once income exceeds £1,000, the allowance can be used in place of expenses, a choice worth making deliberately: a freelancer with £900 of costs is better off with the allowance, one with £3,000 is not.

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.

Workplace pensions and auto-enrolment

Workplace pension compliance is part of payroll, not separate from it. Each pay period the payroll assesses who is eligible, calculates employer and employee contributions on qualifying earnings between the lower and upper thresholds, and sends the contribution file to the scheme. The minimum total is 8%, and many employers choose to contribute more as a recruitment advantage.

Questions

R&D Tax Credits questions from Sydenham

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.

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 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.

Is r&d tax credits in Sydenham really the same price as elsewhere?

Yes. The fee published on this page is what a client in Sydenham, Lewisham 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.
