Worth knowing
Rules that come up in this work
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
VAT registration is compulsory once taxable turnover in any rolling twelve-month period exceeds £90,000, or when you expect to exceed that in the next thirty days alone. The test is rolling, not by tax year, and includes zero-rated sales. Businesses regularly cross it without noticing, and late registration means accounting for VAT on sales where it was never charged to customers.
Director's loan accounts
A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.
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.
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
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.
Questions
Landlord & Property Tax questions from Sidcup
I live abroad and rent out a UK property. Do I still pay UK tax?
Yes. UK rental income is taxed in the UK regardless of your residence, with the personal allowance available to most non-residents. Letting agents or tenants must deduct 20% at source unless you are approved under the Non-Resident Landlord Scheme to receive rent gross. We handle the approval and the annual return.
Should I put my properties into a limited company?
Sometimes. A company deducts mortgage interest in full and pays Corporation Tax at 19% to 25%, but extracting profit costs dividend tax, mortgages are dearer and transferring existing properties triggers CGT and SDLT. It suits higher-rate taxpayers building a portfolio long term; it rarely suits one or two properties. Our tax planning review runs the numbers.
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.
Is replacing a kitchen a repair or an improvement?
Replacing like with like, or with the modern equivalent, is a repair and deductible, even if the new kitchen is better quality because standards have risen. Adding something that was not there before, such as extending the kitchen or adding a dishwasher space, is an improvement and goes against the capital gain instead. We split mixed invoices.
What expenses can I claim?
Letting agent fees, repairs and maintenance, buildings and contents insurance, ground rent and service charges, council tax and utilities you pay, accountancy, legal fees for lets of a year or less, replacing furniture and appliances, mileage to the property, and advertising. Improvements, your own labour and the capital part of mortgage payments are not allowable.
