Worth knowing
Rules that come up in this work
The Self Assessment calendar
Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.
Payments on account
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
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
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.
The VAT registration threshold
The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.
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.
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
Capital Gains Tax questions from Marble Arch
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.
