Worth knowing
Rules that come up in this work
Workplace pensions and auto-enrolment
Auto-enrolment duties begin the day you take on your first employee, not when the Pensions Regulator writes to you. Eligible staff must be enrolled, contributions paid every pay period and re-enrolment carried out every three years. Director-only companies without employment contracts are usually exempt. Fines for non-compliance are fixed and escalating.
Employer National Insurance
Employers pay National Insurance at 15% on each employee's earnings above the £5,000 secondary threshold, following the April 2025 changes. The Employment Allowance offsets up to £10,500 of this for eligible employers, which for a small team often removes the liability entirely, but companies where the director is the only employee do not qualify.
The trading and property allowances
Small side incomes are covered by two £1,000 allowances, one for trading and one for property, which remove the need to register or report income below that level. Once income exceeds £1,000, the allowance can be used in place of expenses, a choice worth making deliberately: a freelancer with £900 of costs is better off with the allowance, one with £3,000 is not.
Dormant companies
Dormancy is a status that is easy to lose. The strict rule is no accounting transactions other than share capital and Companies House fees, which means no bank account activity at all in practice. Fees should be paid personally by the director. A company that traded and has stopped becomes dormant only after its final trading accounts and tax return are filed and HMRC is told.
The 60-day property CGT return
Since April 2020 a gain on UK residential property must be reported and the tax paid within 60 days of completion through HMRC's dedicated service, separately from the annual return. Non-residents must report all UK land disposals in the same window whether or not tax is due. Getting the computation right first time matters because the figure is then carried into the Self Assessment.
Crypto records and reporting
HMRC treats cryptoassets as property. Swapping one token for another, spending crypto or gifting it are all disposals for Capital Gains Tax, and staking and lending rewards are income. Gains are computed under pooling rules with same-day and 30-day matching. From 2026 HMRC receives data from exchanges worldwide under the Cryptoasset Reporting Framework, so unreported activity is increasingly visible.
Allowable expenses
The expenses sole traders most often miss are home working costs, claimed by actual proportion or HMRC's flat rate, the business share of phone and internet, mileage at 45p for the first 10,000 business miles, and training that maintains existing skills. The ones most often claimed wrongly are commuting, entertaining customers and clothes that could be worn outside work.
Questions
Landlord & Property Tax questions from Thamesfield
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.
