Worth knowing

Rules that come up in this work

CIS deductions

The Construction Industry Scheme affects both sides of a construction payment. Contractors must verify subcontractors, deduct the right amount, issue statements and file monthly, with penalties from £100 for each late return. Subcontractors suffer deductions on turnover and recover the excess at the year end. Limited company subcontractors offset deductions against PAYE monthly instead.

Confirmation statements and identity verification

The confirmation statement is the annual check that the public register is right: officers, registered office, SIC codes, shareholders and the PSC register. It carries a £50 fee and no financial penalty for lateness, but failure to file leads to compulsory strike-off. The identity verification regime introduced in November 2025 has added a further check to every statement.

Director's loan accounts

A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.

Salary versus dividends

The salary-and-dividend split is the central planning decision for an owner-managed company. Salary costs employer National Insurance above £5,000 but is deductible; dividends are not deductible but attract lower personal rates and no National Insurance. The optimum changes each April with the thresholds and depends on the director's other income, so it should be set deliberately every year.

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.

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

The biggest change to Self Assessment in a generation is Making Tax Digital for Income Tax, now live for higher-earning sole traders and landlords and arriving for the rest in stages. Quarterly updates are due by 7 August, 7 November, 7 February and 7 May, built from digital records. The practical consequence is that spreadsheet-and-shoebox bookkeeping is ending for anyone above the threshold.

Questions

Making Tax Digital questions from Harmondsworth

Can I do MTD myself without an accountant?

Yes, if you are comfortable keeping the records digitally and submitting four updates and a declaration each year on time. Many sole traders do. The value we add is in the setup being right, the categories mapping correctly to HMRC's lines, the deadlines never being missed and the year-end declaration including the adjustments and allowances that reduce your tax.

What is the full MTD service?

From £299 a year: software subscription guidance, digital record review each quarter, the four quarterly updates submitted, and the year-end final declaration prepared and filed with capital allowances, adjustments and all other income included. It replaces the traditional Self Assessment fee for clients in MTD. Bookkeeping can be added if you would rather not do the recording.

How does MTD for VAT differ?

MTD for VAT has applied to all VAT-registered businesses since April 2022: digital records and returns submitted through compatible software, with the same quarterly return as before. If you are still typing figures into a portal or using software that is not linked, you are non-compliant. Our £129 setup includes the first return filed.

What if my income drops below the threshold later?

Once in MTD you stay in unless your qualifying income falls below the threshold for three consecutive years, after which you can apply to leave. There are exemptions for digital exclusion on grounds of age, disability, location or religion, which must be applied for and granted by HMRC.

What do I actually have to do under MTD for Income Tax?

Keep records of income and expenses digitally in compatible software, send HMRC a quarterly update summarising them by 7 August, 7 November, 7 February and 7 May, and submit a final declaration with any adjustments and other income by 31 January. The tax payment dates are unchanged.

When does Making Tax Digital for Income Tax apply to me?

It depends on your gross self-employment plus property income on your 2024/25 return: over £50,000 means you joined from 6 April 2026; over £30,000 means 6 April 2027; over £20,000 is planned for April 2028. Below £20,000 there is currently no requirement. We check your figures and confirm the date in writing.

Is making tax digital in Harmondsworth really the same price as elsewhere?

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

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