Worth knowing
Rules that come up in this work
Switching accountants
The main reasons people switch accountant are surprise invoices, missed deadlines and not understanding what they are being told. Switching involves a clearance letter between the firms, a transfer of records and agent authorisations, and a short handover of the current position. It takes about two weeks and should cost nothing extra.
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.
Dormant companies
Dormancy is a status that is easy to lose. The strict rule is no accounting transactions other than share capital and Companies House fees, which means no bank account activity at all in practice. Fees should be paid personally by the director. A company that traded and has stopped becomes dormant only after its final trading accounts and tax return are filed and HMRC is told.
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
Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.
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.
Record keeping
HMRC requires records of all income and expenses, bank statements, invoices and receipts to be kept for at least five years after the 31 January filing deadline of the tax year they relate to, and companies must keep records for six years from the end of the accounting period. Digital copies are acceptable. Under Making Tax Digital the records must be kept in compatible software.
Questions
HMRC Investigation Support questions from Greenhill
What penalties can HMRC charge?
For an inaccurate return, 0% to 30% of the extra tax for careless errors, 20% to 70% for deliberate ones and 30% to 100% for deliberate and concealed, with higher ranges for offshore matters. Within each range the penalty depends on whether the disclosure was prompted and how much you help. We work to secure the lowest point in the applicable range and suspension where available.
Can I pay what I owe in instalments?
Usually. HMRC's Time to Pay arrangements spread settlements over months, sometimes years, depending on the amount and your means. Interest runs but further penalties do not if you keep to the agreement. We negotiate the arrangement as part of closing the enquiry, with realistic figures based on your income and assets.
What is a voluntary disclosure and should I make one?
Telling HMRC about an error before it asks. Unprompted disclosures attract much lower penalties, often nil for careless errors, and are the right course when you know a return was wrong. The Digital Disclosure Service, Let Property Campaign and Worldwide Disclosure Facility are the main routes. Our fee from £599 covers preparing and negotiating the disclosure.
I received a nudge letter but I think my return is right. What should I do?
Nudge letters ask you to check and either amend or confirm. Do not sign HMRC's certificate without checking thoroughly, because signing a false one is serious. We review the area HMRC has raised, confirm the position and respond. If the return is right we say so to HMRC clearly; if not, we amend before any enquiry is opened.
Can HMRC go back more than one year?
The normal time limit is four years from the end of the tax year, extended to six for careless behaviour and twenty for deliberate behaviour or failure to notify. If HMRC finds an error in one year it will usually ask about others. Part of our job is holding HMRC to the correct time limit for the behaviour actually shown.
Do I have to attend a meeting with HMRC?
No. You are not obliged to attend a meeting and we often recommend written correspondence instead, which gives considered answers rather than off-the-cuff ones. Where a meeting is useful we attend with you or on your behalf, agree the agenda in advance and take our own notes of what was said.
