Worth knowing
Rules that come up in this work
CIS deductions
CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.
Confirmation statements and identity verification
Every company must file a confirmation statement at least once a year, within fourteen days of its review date, with a £50 Companies House fee. Since November 2025 directors and people with significant control must also verify their identity with Companies House, and the confirmation statement is where existing officers confirm they have done so during the transition year.
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.
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.
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
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.
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.
Questions
Crypto Tax questions from Lime Street
What if I am a trader rather than an investor?
HMRC rarely accepts that an individual is trading in crypto; the bar is very high and the badges of trade must be met. If you are trading, profits are income and losses are trading losses. For almost everyone the capital gains treatment applies, and we tell you plainly which side of the line you are on.
How far back do I need to go?
The pool cost of what you hold today depends on every purchase you have ever made, so the computation must start from your first transaction even if you only need to report recent years. If earlier years were under-reported, we quantify the position and advise on disclosure, which HMRC treats far more leniently than discovery.
Are NFTs treated the same as coins?
Each NFT is a separate asset, so pooling does not apply; the gain is proceeds less the cost of that specific token including gas fees. Creating and selling NFTs regularly may be trading income rather than capital gains. Royalties received are income. We classify each case from the facts.
Do I need to register for Self Assessment just for crypto?
If your total disposals exceed £50,000 in the year, or your gains exceed the £3,000 allowance, or you have taxable crypto income, yes. Register by 5 October after the tax year. Since 2024/25 the return has a dedicated section for cryptoassets. We handle registration where you are not already filing.
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.
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.
How do I get started from Lime Street?
Message us on WhatsApp or email with a sentence about your business and what you need. We reply in working hours with any questions and a fixed fee for crypto tax. Once you confirm, we tell you exactly which records to send and the work begins. Most Lime Street clients are set up within a day.
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 Lime Street 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.
