Worth knowing
Rules that come up in this work
Confirmation statements and identity verification
Companies House has tightened its requirements under the Economic Crime and Corporate Transparency Act: every company needs a registered email address and an appropriate registered office, every statement includes a lawful-purpose declaration, and every director and PSC must verify their identity. The confirmation statement, due annually with a £50 fee, is where most of this is confirmed.
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.
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
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
Directors of their own companies usually take a salary at or just above the National Insurance thresholds, which keeps the year qualifying for State Pension and is deductible for Corporation Tax, with further income as dividends. Dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% by band and can only be paid from distributable profits after tax, with a minute and voucher each time.
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
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.
Questions
Crypto Tax questions from Sidcup
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.
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.
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.
