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

Companies House has tightened its requirements under the Economic Crime and Corporate Transparency Act: every company needs a registered email address and an appropriate registered office, every statement includes a lawful-purpose declaration, and every director and PSC must verify their identity. The confirmation statement, due annually with a £50 fee, is where most of this is confirmed.

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

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

Capital Gains Tax questions from Westminster

I am an executor. Do I report gains for the estate?

Yes. During the administration period the estate is a separate taxpayer with its own annual exemption and pays CGT at 24% on gains above probate value. Residential property sales by the estate are subject to the 60-day rule. We prepare the estate computations and the trust and estate return pages.

I am not UK resident but sold a UK property. Do I need to report?

Yes. Non-residents must report all UK land and property disposals within 60 days, whether or not tax is due, and residential property gains are generally rebased to April 2015 values. The rules differ from those for residents and the penalties for not reporting are the same. We handle non-resident returns regularly.

What if I sell shares from an employee share scheme?

It depends on the scheme. Shares from a SAYE or SIP scheme have specific cost rules and sometimes income tax has already been paid on part of the value. Options exercised and sold on the same day may have no gain at all. We need the scheme documents and the exercise and sale figures, and we apply the correct treatment for each.

Do transfers between spouses trigger tax?

No. Transfers between spouses or civil partners living together are at no gain and no loss; the recipient takes over the original cost. This allows both annual exemptions and both basic rate bands to be used on a later sale, which is a common and legitimate way to reduce the tax on a jointly planned disposal.

What is the 60-day property return?

When a UK resident sells UK residential property and tax is due, they must file a return through HMRC's Capital Gains Tax on UK property service and pay the tax within 60 days of completion. This is separate from and in addition to the annual Self Assessment. Late filing penalties mirror Self Assessment: £100 immediately, then daily and tax-geared penalties.

What are the Capital Gains Tax rates for 2026/27?

The annual exempt amount is £3,000. Gains above it are taxed at 18% to the extent they fall within your unused basic rate band and 24% above it, for all asset types including residential property. Gains qualifying for business asset disposal relief are taxed at 14% in 2025/26, rising to 18% from April 2026, on up to £1 million of lifetime gains.

Is capital gains tax in Westminster really the same price as elsewhere?

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

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