    You receive one price for the work, confirmed by email before anything starts. It does not change if the job takes longer than we expected.

  3. Send records, review the draft

    Records come by WhatsApp or email. We prepare the draft, explain the figures in plain English and answer your questions.

  4. We file, you get the receipts

    Once you approve and the fee is settled, we submit electronically and forward the HMRC or Companies House acknowledgement the same day.

Why IGI

Why St James's businesses file with IGI

No hourly rate and no surprise invoice. St James's clients know the fee for capital gains tax before they send a single document, and it stays fixed.

We work to the HMRC and Companies House calendar, not an appointment diary. Clients in St James's get reminders at 60, 30 and 7 days before each date that applies to capital gains tax.

Online only, UK based. There is no office in St James's to pay for, which is why the fee is the same here as anywhere in England; the work is done by people in the UK who answer the same day.

Continuity matters in capital gains tax: the person who prepared last year's work for your St James's business prepares this year's, and remembers what was agreed.

We explain capital gains tax in the words St James's business owners use, not in accountant's shorthand, and we show our working so you can check it.

Nothing is filed for St James's until you have reviewed and approved it. You see the draft, you ask questions, you sign off, then we submit and send you the receipt.

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

Voluntary strike-off is available only to solvent companies. One that owes money it cannot pay needs a creditors' voluntary liquidation through a licensed insolvency practitioner, and directors who dissolve an insolvent company face personal consequences. For a solvent company the process takes three to four months from filing the DS01, with notice to creditors and shareholders within seven days.

Record keeping

Good records are the difference between a quick enquiry and a long one. For the self-employed, five years after the filing deadline; for companies, six years from the year end; for VAT, six years. Photographs of receipts, PDF statements and software exports all count. The requirement is to keep records, not paper, and a well-organised cloud folder satisfies it.

Allowable expenses

An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do 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.

The 60-day property CGT return

Since April 2020 a gain on UK residential property must be reported and the tax paid within 60 days of completion through HMRC's dedicated service, separately from the annual return. Non-residents must report all UK land disposals in the same window whether or not tax is due. Getting the computation right first time matters because the figure is then carried into the Self Assessment.

Dormant companies

Companies formed to protect a name or hold a future business are dormant but not exempt: Companies House still expects dormant accounts within nine months of the year end and a confirmation statement annually with its £50 fee, and HMRC must be told the company is dormant or it will demand Corporation Tax returns. The filings are short, but the penalties for missing them are the same as for a trading company.

Questions

Capital Gains Tax questions from St James's

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 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.

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.

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.

I sold my former home that I later let out. Is it all taxable?

No. Private residence relief exempts the gain for the period you lived there plus the final nine months of ownership, and certain periods of absence can qualify. The let period is taxable. Lettings relief now applies only where you shared occupation with the tenant. We apportion the gain by days and claim every qualifying period.

What costs can I deduct from the gain?

The purchase price, stamp duty and legal fees on purchase, capital improvements that are still reflected in the asset at sale (extensions, new kitchens, not repairs), and selling costs including agent and legal fees. For shares, dealing costs and stamp duty. For inherited assets, the probate value is the cost.
