Worth knowing

Rules that come up in this work

Corporation Tax rates and marginal relief

Companies pay Corporation Tax at 19% on profits up to £50,000 and 25% on profits over £250,000. Between those figures marginal relief applies, producing an effective rate that rises gradually and a marginal rate of 26.5% on each pound in the band. The thresholds are divided by the number of associated companies, so a director with two companies has thresholds of £25,000 and £125,000 for each.

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

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

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.

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.

Questions

Landlord & Property Tax questions from Carshalton South and Clockhouse

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.

How is mortgage interest treated now?

Since April 2020 individual landlords cannot deduct mortgage interest or other finance costs from rental profit. Instead you receive a tax reduction of 20% of the finance costs. For higher-rate taxpayers this means more tax than under the old rules, and the restriction can push rental profit into a higher band. We calculate it and carry forward any unused credit.

What is included in the £149 one-property fee?

The rental income and expenditure account for the property, a review of every expense category, the finance-cost credit calculation, the UK property pages and the rest of your Self Assessment return completed and filed with HMRC. Rental income alongside employment or a pension is the most common case and this fee covers it.
