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
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.
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
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.
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.
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.
Questions
HMRC Investigation Support questions from Sidcup
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.
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.
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.
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.
Do you have an office in Sidcup?
No. IGI Accounting is an online-only firm. We serve Sidcup 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 Sidcup as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is hmrc investigation support in Sidcup really the same price as elsewhere?
Yes. The fee published on this page is what a client in Sidcup 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.
