Worth knowing

Rules that come up in this 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.

Director's loan accounts

The most common tax problem in owner-managed companies is an overdrawn director's loan account: drawings taken during the year that were never declared as dividends or salary. The company faces a 35.75% charge on the balance outstanding nine months after the year end, and the director may have a benefit in kind. We review the account before every year end to clear it properly.

The VAT registration threshold

Watching the rolling twelve-month turnover figure is one of the quiet jobs of monthly bookkeeping, because the £90,000 VAT threshold arrives silently. Crossing it brings quarterly returns, Making Tax Digital software and a decision about schemes. Crossing it late brings a bill for VAT you could not recover from customers and a penalty for failing to notify.

Corporation Tax rates and marginal relief

Companies pay Corporation Tax at 19% on profits up to £50,000 and 25% on profits over £250,000. Between those figures marginal relief applies, producing an effective rate that rises gradually and a marginal rate of 26.5% on each pound in the band. The thresholds are divided by the number of associated companies, so a director with two companies has thresholds of £25,000 and £125,000 for each.

Late filing penalties

Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.

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.

The Self Assessment calendar

Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.

Questions

HMRC Investigation Support questions from Thamesfield

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 Thamesfield?

No. IGI Accounting is an online-only firm. We serve Thamesfield 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 Thamesfield as anywhere else in the country, and why there is nothing to visit and nothing to print.

Is hmrc investigation support in Thamesfield really the same price as elsewhere?

Yes. The fee published on this page is what a client in Thamesfield 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.
