Worth knowing

Rules that come up in this work

Director's loan accounts

Money taken from a company has to be something: salary, dividend, expense reimbursement or loan. If it is a loan and remains outstanding nine months after the year end, the company pays tax at the dividend higher rate on it until it is repaid. Clearing the balance with a properly declared dividend before the deadline, where reserves allow, is routine year-end work.

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

VAT registration is compulsory once taxable turnover in any rolling twelve-month period exceeds £90,000, or when you expect to exceed that in the next thirty days alone. The test is rolling, not by tax year, and includes zero-rated sales. Businesses regularly cross it without noticing, and late registration means accounting for VAT on sales where it was never charged to customers.

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.

Late filing penalties

Lateness is expensive in a way that compounds. For individuals, £100 immediately, then daily penalties, then percentage-based ones at six and twelve months, with interest running on unpaid tax throughout. For companies, Companies House penalties scale with delay and double on repeat, and HMRC adds its own for a late CT600. Filing on time is the cheapest tax planning there is.

Payments on account

A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.

Questions

Crypto Tax questions from Portsmouth

How are gains calculated with so many purchases at different prices?

HMRC requires pooling: all units of the same token form one section 104 pool with an average cost, except that disposals are first matched against purchases on the same day and then against purchases within the following 30 days. We apply these rules across your entire history, which is impossible to do accurately by hand at any volume.

Do I pay tax if I never cashed out to pounds?

Usually yes. Swapping one cryptoasset for another, spending crypto on goods or services, and gifting it to anyone other than a spouse are all disposals for Capital Gains Tax, valued in sterling at the time. Only moving coins between your own wallets is not a disposal. Most people's taxable events are swaps, not sales for cash.

Is staking income a capital gain?

No. Rewards from staking, lending, liquidity provision and most DeFi protocols are income when received, taxed at your income tax rate on the sterling value that day, and reported as miscellaneous income unless your activity amounts to a trade. The tokens then enter your pool at that value for a later capital gain or loss.

What are the Capital Gains Tax rates and allowance?

The annual exempt amount is £3,000 for 2026/27. Gains above it are taxed at 18% within your basic rate band and 24% above it. Losses in the year are set against gains automatically, and unused losses can be carried forward indefinitely if claimed on a return within four years.

What do you need from me?

Full transaction exports from every exchange you have used, including closed accounts, and wallet addresses for on-chain activity. Partial history produces wrong pool costs, so completeness matters more than tidiness. We tell you exactly how to export from each major platform.

My exchange collapsed and I lost everything. Can I claim the loss?

Possibly. If the tokens still exist but you cannot access them, a negligible value claim may be available once the asset is effectively worthless. If the exchange is in administration you may need to wait for the outcome. We assess each case against HMRC's guidance and make the claim where it is supportable.

Is crypto tax in Portsmouth really the same price as elsewhere?

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

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