Worth knowing
Rules that come up in this work
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.
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.
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.
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.
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.
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.
Questions
HMRC Investigation Support questions from Carshalton South and Clockhouse
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.
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.
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.
