Worth knowing
Rules that come up in this work
CIS deductions
Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.
Confirmation statements and identity verification
Every company must file a confirmation statement at least once a year, within fourteen days of its review date, with a £50 Companies House fee. Since November 2025 directors and people with significant control must also verify their identity with Companies House, and the confirmation statement is where existing officers confirm they have done so during the transition year.
Director's loan accounts
Money taken from a company has to be something: salary, dividend, expense reimbursement or loan. If it is a loan and remains outstanding nine months after the year end, the company pays tax at the dividend higher rate on it until it is repaid. Clearing the balance with a properly declared dividend before the deadline, where reserves allow, is routine year-end work.
Salary versus dividends
Directors of their own companies usually take a salary at or just above the National Insurance thresholds, which keeps the year qualifying for State Pension and is deductible for Corporation Tax, with further income as dividends. Dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% by band and can only be paid from distributable profits after tax, with a minute and voucher each time.
Corporation Tax rates and marginal relief
Since April 2023 there have been two Corporation Tax rates, 19% small profits and 25% main, with marginal relief smoothing the transition between £50,000 and £250,000 of profit. The band is where planning matters: each pound of profit in it is taxed at an effective 26.5%, so pension contributions and capital expenditure timed to keep profit below £50,000 are worth more than they look.
The VAT registration threshold
The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.
Making Tax Digital for Income Tax
Making Tax Digital for Income Tax began in April 2026 for sole traders and landlords with qualifying income over £50,000, extends to those over £30,000 in April 2027 and is planned for £20,000 in April 2028. It requires digital records in compatible software and four quarterly updates to HMRC each year, with a final declaration replacing the traditional return. Payment dates are unchanged.
Questions
HMRC Investigation Support questions from Didcot
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 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.
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.
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.
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.
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.
Is hmrc investigation support in Didcot really the same price as elsewhere?
Yes. The fee published on this page is what a client in Didcot 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.
Do you have an office in Didcot?
No. IGI Accounting is an online-only firm. We serve Didcot 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 Didcot as anywhere else in the country, and why there is nothing to visit and nothing to print.
