Worth knowing
Rules that come up in this work
Making Tax Digital for Income Tax
The biggest change to Self Assessment in a generation is Making Tax Digital for Income Tax, now live for higher-earning sole traders and landlords and arriving for the rest in stages. Quarterly updates are due by 7 August, 7 November, 7 February and 7 May, built from digital records. The practical consequence is that spreadsheet-and-shoebox bookkeeping is ending for anyone above the threshold.
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.
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
The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.
Director's loan accounts
Money taken from a company has to be something: salary, dividend, expense reimbursement or loan. If it is a loan and remains outstanding nine months after the year end, the company pays tax at the dividend higher rate on it until it is repaid. Clearing the balance with a properly declared dividend before the deadline, where reserves allow, is routine year-end work.
Salary versus dividends
Directors of their own companies usually take a salary at or just above the National Insurance thresholds, which keeps the year qualifying for State Pension and is deductible for Corporation Tax, with further income as dividends. Dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% by band and can only be paid from distributable profits after tax, with a minute and voucher each time.
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
Landlord & Property Tax questions from South West London
I have been letting for years and never declared it. What now?
HMRC's Let Property Campaign allows landlords to disclose undeclared rental income with lower penalties than if HMRC finds it, which with data from letting agents, deposit schemes and councils it increasingly does. We quantify the undeclared years, prepare the disclosure and negotiate the settlement. Acting first is always cheaper.
I rent out a room in my own home. Is that taxable?
Rent-a-room relief exempts the first £7,500 a year of income from letting furnished accommodation in your main home, or £3,750 each if the income is shared. Above that you can pay tax on the excess over £7,500 or on actual profit. Lodgers, Airbnb rooms and short-term lets of a room all qualify.
What happened to furnished holiday lets?
The furnished holiday let regime ended on 5 April 2025. Holiday lets are now taxed like other residential lets: the finance-cost restriction applies, capital allowances on furniture are replaced by replacement relief, and the capital gains reliefs are withdrawn with transitional rules. Our £249 holiday let service handles the transition and the new treatment.
My partner and I own a property jointly. How is the income split?
Married couples and civil partners are taxed 50/50 by default regardless of actual ownership, unless you own in unequal shares and file Form 17 with evidence to be taxed on your actual shares. Unmarried joint owners are taxed on their actual shares. Choosing the right split can save tax where one of you is in a lower band.
What is the property allowance?
The first £1,000 of gross rental income each year is tax free, and if your rental income is under £1,000 you need not report it. Above £1,000 you can either deduct the allowance instead of expenses or claim actual expenses, whichever is better. It cannot be used with rent-a-room relief on the same income.
Do I have to use Making Tax Digital?
From April 2026 if your combined property and self-employment income was over £50,000 in 2024/25, from April 2027 if over £30,000, and planned for April 2028 at £20,000. It means digital records and quarterly updates to HMRC. We assess your start date as part of the return and set up the bookkeeping when it applies.
Is landlord & property tax in South West London really the same price as elsewhere?
Yes. The fee published on this page is what a client in South West 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.
Do you have an office in South West London?
No. IGI Accounting is an online-only firm. We serve South West London and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for landlord & property tax is the same in South West London as anywhere else in the country, and why there is nothing to visit and nothing to print.
