Worth knowing
Rules that come up in this work
Confirmation statements and identity verification
Every company must file a confirmation statement at least once a year, within fourteen days of its review date, with a £50 Companies House fee. Since November 2025 directors and people with significant control must also verify their identity with Companies House, and the confirmation statement is where existing officers confirm they have done so during the transition year.
CIS deductions
Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.
Late filing penalties
Lateness is expensive in a way that compounds. For individuals, £100 immediately, then daily penalties, then percentage-based ones at six and twelve months, with interest running on unpaid tax throughout. For companies, Companies House penalties scale with delay and double on repeat, and HMRC adds its own for a late CT600. Filing on time is the cheapest tax planning there is.
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 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.
Payments on account
If your Self Assessment bill exceeds £1,000 and less than 80% of your tax was collected at source, HMRC asks for two advance payments towards the following year, each half of the current bill, due 31 January and 31 July. The first year this happens the January payment is effectively one and a half times the bill. We model it in advance and show you how to reduce the payments if income is falling.
Salary versus dividends
Paying yourself from a company involves two routes with different tax treatment. Salary through payroll is a company expense and builds a National Insurance record; dividends come from post-tax profit at lower personal rates. Undocumented drawings that are neither become director's loans, with a 35.75% section 455 charge if not repaid within nine months of the year end.
Questions
Capital Gains Tax questions from City of London
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.
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.
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.
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.
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.
Do you have an office in City of London?
No. IGI Accounting is an online-only firm. We serve City of London and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically.

Yes. The fee published on this page is what a client in City of London pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
