Worth knowing

Rules that come up in this work

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

Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.

The 60-day property CGT return

The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.

Dormant companies

Dormancy is a status that is easy to lose. The strict rule is no accounting transactions other than share capital and Companies House fees, which means no bank account activity at all in practice. Fees should be paid personally by the director. A company that traded and has stopped becomes dormant only after its final trading accounts and tax return are filed and HMRC is told.

The trading and property allowances

Small side incomes are covered by two £1,000 allowances, one for trading and one for property, which remove the need to register or report income below that level. Once income exceeds £1,000, the allowance can be used in place of expenses, a choice worth making deliberately: a freelancer with £900 of costs is better off with the allowance, one with £3,000 is not.

Employer National Insurance

The cost of an employee is more than the salary. Employer National Insurance at 15% above £5,000 a year, the 3% minimum pension contribution, holiday pay, equipment and management time all come on top. The Employment Allowance of £10,500 reduces the National Insurance for most employers with more than one person on the payroll.

Questions

Capital Gains Tax questions from Marylebone

I am not UK resident but sold a UK property. Do I need to report?

Yes. Non-residents must report all UK land and property disposals within 60 days, whether or not tax is due, and residential property gains are generally rebased to April 2015 values. The rules differ from those for residents and the penalties for not reporting are the same. We handle non-resident returns regularly.

I am an executor. Do I report gains for the estate?

Yes. During the administration period the estate is a separate taxpayer with its own annual exemption and pays CGT at 24% on gains above probate value. Residential property sales by the estate are subject to the 60-day rule. We prepare the estate computations and the trust and estate return pages.

What are the Capital Gains Tax rates for 2026/27?

The annual exempt amount is £3,000. Gains above it are taxed at 18% to the extent they fall within your unused basic rate band and 24% above it, for all asset types including residential property. Gains qualifying for business asset disposal relief are taxed at 14% in 2025/26, rising to 18% from April 2026, on up to £1 million of lifetime gains.

What is the 60-day property return?

When a UK resident sells UK residential property and tax is due, they must file a return through HMRC's Capital Gains Tax on UK property service and pay the tax within 60 days of completion. This is separate from and in addition to the annual Self Assessment. Late filing penalties mirror Self Assessment: £100 immediately, then daily and tax-geared penalties.

I sold my former home that I later let out. Is it all taxable?

No. Private residence relief exempts the gain for the period you lived there plus the final nine months of ownership, and certain periods of absence can qualify. The let period is taxable. Lettings relief now applies only where you shared occupation with the tenant. We apportion the gain by days and claim every qualifying period.

What costs can I deduct from the gain?

The purchase price, stamp duty and legal fees on purchase, capital improvements that are still reflected in the asset at sale (extensions, new kitchens, not repairs), and selling costs including agent and legal fees. For shares, dealing costs and stamp duty. For inherited assets, the probate value is the cost.
