Worth knowing
Rules that come up in this work
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
Selling UK residential property that was not your main home for the whole period of ownership triggers a separate Capital Gains Tax return, due within 60 days of completion along with payment of the tax. This is in addition to the annual Self Assessment. The gain is taxed at 18% or 24% depending on your income band, after the £3,000 annual exempt amount.
Record keeping
Record keeping is a legal obligation with a penalty of up to £3,000 for failure, but its real value is in making every other filing cheaper and more defensible. Keep invoices, receipts, bank statements, mileage logs and any HMRC correspondence, digitally if you like, for five years after the relevant filing deadline for individuals and six years for companies and VAT.
Allowable expenses
The expenses sole traders most often miss are home working costs, claimed by actual proportion or HMRC's flat rate, the business share of phone and internet, mileage at 45p for the first 10,000 business miles, and training that maintains existing skills. The ones most often claimed wrongly are commuting, entertaining customers and clothes that could be worn outside work.
Employer National Insurance
Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
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 Southampton
What is business asset disposal relief?
Formerly entrepreneurs' relief: a reduced rate on gains from selling all or part of a trading business, or shares in a trading company where you held at least 5% and were an officer or employee for two years. The lifetime limit is £1 million. The rate rose to 14% in April 2025 and to 18% from April 2026. Our £299 service prepares and supports the claim.
I gave a property to my child. Is there tax?
Yes. Gifts to anyone other than your spouse or civil partner are disposals at market value, and the gain is taxable even though no money changed hands. The 60-day return applies to residential property. Gift relief can defer gains on business assets, but not on investment property. We value, compute and report the gift.
How do you work out gains on shares bought at different times?
Disposals are matched first to shares bought the same day, then to shares bought in the following 30 days, then to the section 104 pool, which holds all other shares of that class at their average cost. The same rules apply to funds and to crypto. We run the matching across your full history.
Can I use losses from previous years?
Yes, if they were claimed on a return within four years of the tax year in which they arose. Current-year losses are set against current-year gains first, even if that wastes the annual exemption; brought-forward losses are only used to the extent needed to bring gains down to the exemption. We check for unclaimed historical losses as standard.
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.
Do you have an office in Southampton?
No. IGI Accounting is an online-only firm. We serve Southampton 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 Southampton as anywhere else in the country, and why there is nothing to visit and nothing to print.
Is capital gains tax in Southampton really the same price as elsewhere?
Yes. The fee published on this page is what a client in Southampton 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.
