Worth knowing
Rules that come up in this work
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.
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.
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.
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.
The Self Assessment calendar
The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.
Payments on account
Payments on account catch out most people in their second year of self-employment. HMRC assumes next year's tax will match this year's and collects half in January and half in July, in advance, on top of the balancing payment. If profits are dropping you can apply to reduce them, but reducing them too far attracts interest. We calculate the right figure rather than guessing.
Late filing penalties
HMRC's penalties for a late Self Assessment return are automatic: £100 the day after 31 January, £10 a day from three months late up to £900, then the greater of £300 or 5% of the tax at six and twelve months. Interest and separate late-payment penalties apply to the tax itself. Companies House charges £150 to £1,500 for late accounts, doubling for a second consecutive year.
Questions
Crypto Tax questions from South Harefield
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.
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.
How is the fee set?
By transaction count. Up to 500 transactions across all exchanges and wallets is £199 for the report alone or £279 with your Self Assessment filed. Over 500 is £399. A response to an HMRC nudge letter, including the report and the reply, is £249. We confirm the band from your exports before starting.
I received an HMRC letter about crypto. What should I do?
Do not ignore it and do not reply without the figures. HMRC's nudge letters are sent where exchange data suggests undeclared activity. We prepare the full report, work out what should have been declared, and draft the response, including a voluntary disclosure where tax is owed, which reduces penalties substantially compared with being caught.
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.
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.

The next four dates that apply to crypto tax are shown at the top of this page, calculated from today. For South Harefield clients we diarise every one of them from the day you join and send reminders before each, so the work is done in good time rather than in the last week before a penalty.
