Worth knowing
Rules that come up in this work
The Self Assessment calendar
Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.
Payments on account
If your Self Assessment bill exceeds £1,000 and less than 80% of your tax was collected at source, HMRC asks for two advance payments towards the following year, each half of the current bill, due 31 January and 31 July. The first year this happens the January payment is effectively one and a half times the bill. We model it in advance and show you how to reduce the payments if income is falling.
Late filing penalties
Penalties are the clearest reason to work to deadlines. A Self Assessment return one day late costs £100 regardless of whether any tax is due; three months late adds £10 a day. Late company accounts start at £150 and reach £1,500, and double if the previous year was also late. None of this is negotiable afterwards except through a narrow reasonable-excuse appeal.
Making Tax Digital for Income Tax
The biggest change to Self Assessment in a generation is Making Tax Digital for Income Tax, now live for higher-earning sole traders and landlords and arriving for the rest in stages. Quarterly updates are due by 7 August, 7 November, 7 February and 7 May, built from digital records. The practical consequence is that spreadsheet-and-shoebox bookkeeping is ending for anyone above the threshold.
The VAT registration threshold
Watching the rolling twelve-month turnover figure is one of the quiet jobs of monthly bookkeeping, because the £90,000 VAT threshold arrives silently. Crossing it brings quarterly returns, Making Tax Digital software and a decision about schemes. Crossing it late brings a bill for VAT you could not recover from customers and a penalty for failing to notify.
Corporation Tax rates and marginal relief
Corporation Tax is not a flat rate. Profits to £50,000 pay 19%, profits above £250,000 pay 25%, and the band between is taxed at an effective marginal rate of 26.5% through the marginal relief mechanism. Associated companies share the thresholds, which catches directors who own more than one company and is the most common cause of underpaid tax in owner-managed groups.
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.
Questions
Crypto Tax questions from Longthornton
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.
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.
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.
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.
Which deadlines matter most for crypto tax?
The next four dates that apply to crypto tax are shown at the top of this page, calculated from today. For Longthornton 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.
