Worth knowing

Rules that come up in this work

Switching accountants

Changing accountant is simpler than most people fear. You authorise the new firm, which writes to the old one for professional clearance and your records; the outgoing accountant must hand over your own documents and usually does within two weeks. The new firm registers as your agent with HMRC and picks up the next filing. There is no need to wait for a year end.

Closing a company

A solvent company that has finished its purpose can be dissolved by voluntary strike-off: form DS01 with a £13 Companies House fee, after three months without trading and with all debts paid, final accounts and tax return filed, and assets distributed. HMRC objects to any application where returns or tax are outstanding, so the sequence matters more than the form.

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

HMRC treats cryptoassets as property. Swapping one token for another, spending crypto or gifting it are all disposals for Capital Gains Tax, and staking and lending rewards are income. Gains are computed under pooling rules with same-day and 30-day matching. From 2026 HMRC receives data from exchanges worldwide under the Cryptoasset Reporting Framework, so unreported activity is increasingly visible.

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

A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.

Questions

HMRC Investigation Support questions from Marlow

What if I disagree with HMRC's conclusion?

You can request a statutory review by an officer not involved in the case, which overturns or varies around a third of decisions, and you can appeal to the First-tier Tribunal within 30 days. We advise on the merits honestly and handle both routes; the £249 penalty appeal fee covers a review request or appeal against a penalty decision.

Will my previous accountant's errors be held against me?

The law holds you responsible for your return, but relying on a competent adviser and giving them full information is a reasonable excuse for many penalties. We establish what happened and present it to HMRC. If the adviser was negligent you may have a claim against them, which we help you document.

What is the difference between a compliance check and an investigation?

A compliance check is HMRC's standard term for any review of a return, from a single question to a full examination of a year's records. Most are routine. A Code of Practice 9 investigation is reserved for suspected serious fraud and works very differently, offering immunity from prosecution in return for full disclosure. We tell you which you are facing from the letter.

What does the £299 first stage cover?

Reviewing HMRC's letter and the return or period concerned, assessing what HMRC is likely to be looking at and your exposure, arranging agent authorisation, and preparing and sending the first response within HMRC's deadline. At the end you know where you stand and what the next stage would cost, and you decide whether to proceed.

Should I just send HMRC everything they ask for?

No. HMRC is entitled to information reasonably required to check the return, and no more. Requests for private bank statements, several years of records or information about other people are often wider than the law allows. Giving too much lengthens the enquiry and can open new lines. We give HMRC what it is entitled to, promptly and completely.

How long does an enquiry take?

A straightforward aspect enquiry into one item can close in two to three months. A full enquiry into a year's records typically takes six to twelve months, longer if HMRC extends to other years. We keep the process moving by responding within deadlines and pressing HMRC to do the same, and we apply for a closure notice if HMRC stalls.
