Worth knowing
Rules that come up in this work
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
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.
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
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.
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.
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.
Director's loan accounts
The most common tax problem in owner-managed companies is an overdrawn director's loan account: drawings taken during the year that were never declared as dividends or salary. The company faces a 35.75% charge on the balance outstanding nine months after the year end, and the director may have a benefit in kind. We review the account before every year end to clear it properly.
Questions
Capital Gains Tax questions from Thamesmead
I gave a property to my child. Is there tax?
Yes. Gifts to anyone other than your spouse or civil partner are disposals at market value, and the gain is taxable even though no money changed hands. The 60-day return applies to residential property. Gift relief can defer gains on business assets, but not on investment property. We value, compute and report the gift.
What is business asset disposal relief?
Formerly entrepreneurs' relief: a reduced rate on gains from selling all or part of a trading business, or shares in a trading company where you held at least 5% and were an officer or employee for two years. The lifetime limit is £1 million. The rate rose to 14% in April 2025 and to 18% from April 2026. Our £299 service prepares and supports the claim.
Can I use losses from previous years?
Yes, if they were claimed on a return within four years of the tax year in which they arose. Current-year losses are set against current-year gains first, even if that wastes the annual exemption; brought-forward losses are only used to the extent needed to bring gains down to the exemption. We check for unclaimed historical losses as standard.
How do you work out gains on shares bought at different times?
Disposals are matched first to shares bought the same day, then to shares bought in the following 30 days, then to the section 104 pool, which holds all other shares of that class at their average cost. The same rules apply to funds and to crypto. We run the matching across your full history.
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.
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.
