Worth knowing
Rules that come up in this work
The trading and property allowances
The first £1,000 of trading income and, separately, the first £1,000 of property income each year is tax free under the trading and property allowances. Below those figures no return is needed for that income. Above them you can deduct the £1,000 allowance instead of actual expenses if that is better, which suits side businesses and single-room lets with few costs.
Dormant companies
A dormant company is one with no significant accounting transactions in the year, where the only permitted entries are the payment for shares on incorporation, Companies House fees and penalties. It still files a confirmation statement and simplified dormant accounts every year. A bank charge or an accountant's fee paid from the company ends dormancy and requires full accounts.
The 60-day property CGT return
Selling UK residential property that was not your main home for the whole period of ownership triggers a separate Capital Gains Tax return, due within 60 days of completion along with payment of the tax. This is in addition to the annual Self Assessment. The gain is taxed at 18% or 24% depending on your income band, after the £3,000 annual exempt amount.
Crypto records and reporting
Most crypto holders have taxable events they do not recognise, because every swap is a disposal even when no pounds change hands. The computation requires the complete transaction history from every exchange and wallet, pooled by asset with HMRC's matching rules applied. Exchange-generated tax reports are frequently wrong because they cannot see transfers between a user's own wallets.
Allowable expenses
An expense is allowable against trading profit if it is incurred wholly and exclusively for the business. Materials, business travel other than ordinary commuting, a proportion of home running costs, software, insurance, professional fees, bank charges and protective clothing qualify. Client entertainment, ordinary clothing, fines and the private share of mixed-use costs do not.
Record keeping
HMRC requires records of all income and expenses, bank statements, invoices and receipts to be kept for at least five years after the 31 January filing deadline of the tax year they relate to, and companies must keep records for six years from the end of the accounting period. Digital copies are acceptable. Under Making Tax Digital the records must be kept in compatible software.
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 Sipson
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.
