Worth knowing
Rules that come up in this work
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.
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
Not every small income needs a tax return. The trading allowance exempts the first £1,000 of self-employment or casual income and the property allowance does the same for rental income, each measured on gross receipts. They cannot be combined with rent-a-room relief on the same income, and claiming the allowance means giving up the expense deduction for that source.
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
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.
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 City of London
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.
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.
Do you have an office in City of London?
No. IGI Accounting is an online-only firm. We serve City of London and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for hmrc investigation support is the same in City of London as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is hmrc investigation support in City of London really the same price as elsewhere?
Yes. The fee published on this page is what a client in City of London 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. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
