Worth knowing

Rules that come up in this work

Dormant companies

A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.

The trading and property allowances

The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.

Employer National Insurance

Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.

Workplace pensions and auto-enrolment

Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.

Record keeping

HMRC requires records of all income and expenses, bank statements, invoices and receipts to be kept for at least five years after the 31 January filing deadline of the tax year they relate to, and companies must keep records for six years from the end of the accounting period. Digital copies are acceptable. Under Making Tax Digital the records must be kept in compatible software.

Allowable expenses

The expenses sole traders most often miss are home working costs, claimed by actual proportion or HMRC's flat rate, the business share of phone and internet, mileage at 45p for the first 10,000 business miles, and training that maintains existing skills. The ones most often claimed wrongly are commuting, entertaining customers and clothes that could be worn outside work.

Crypto records and reporting

HMRC treats cryptoassets as property. Swapping one token for another, spending crypto or gifting it are all disposals for Capital Gains Tax, and staking and lending rewards are income. Gains are computed under pooling rules with same-day and 30-day matching. From 2026 HMRC receives data from exchanges worldwide under the Cryptoasset Reporting Framework, so unreported activity is increasingly visible.

Questions

Crypto Tax questions from Sipson

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.

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.

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.

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 Sipson 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.
