Worth knowing
Rules that come up in this work
CIS deductions
CIS turns construction subcontractors into advance taxpayers: a fifth of every labour payment goes to HMRC before they see it. Registering keeps the rate at 20% rather than 30%; gross payment status, for established businesses with a clean record, removes deductions altogether. The annual return is where the overpayment comes back, and filing it early brings the refund sooner.
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.
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
The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.
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
The salary-and-dividend split is the central planning decision for an owner-managed company. Salary costs employer National Insurance above £5,000 but is deductible; dividends are not deductible but attract lower personal rates and no National Insurance. The optimum changes each April with the thresholds and depends on the director's other income, so it should be set deliberately every year.
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.
Questions
Landlord & Property Tax questions from Southwark
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.
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.
