Worth knowing
Rules that come up in this work
Closing a company
A solvent company that has finished its purpose can be dissolved by voluntary strike-off: form DS01 with a £13 Companies House fee, after three months without trading and with all debts paid, final accounts and tax return filed, and assets distributed. HMRC objects to any application where returns or tax are outstanding, so the sequence matters more than the form.
Switching accountants
You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.
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.
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.
The 60-day property CGT return
The 60-day Capital Gains Tax return on residential property is the deadline landlords most often miss, because it falls outside the Self Assessment cycle and runs from completion, not exchange. Private residence relief for periods you lived in the property, plus the final nine months, reduces the gain. Penalties for a late return mirror Self Assessment, starting at £100.
Crypto records and reporting
Crypto tax splits into capital gains on disposals and income on rewards, with different rates and different reporting. The £3,000 annual exempt amount and the 18% and 24% rates apply to gains; staking, mining and airdrop income is taxed at marginal income tax rates. HMRC's nudge letters to holders have increased sharply, and a voluntary disclosure before one arrives is treated far more leniently.
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.
Questions
Landlord & Property Tax questions from London
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.
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.
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.
Is landlord & property tax in London really the same price as elsewhere?
Yes. The fee published on this page is what a client in London pays and what a client in any other part of England pays. It is confirmed in writing before work starts and the invoice matches the quote. Where a higher package applies because your situation is more complex, we say so at the quote stage, never afterwards.
Do you have an office in London?
No. IGI Accounting is an online-only firm. We serve London and every other UK postcode remotely, with records sent by WhatsApp or email and everything filed electronically. The absence of local premises is why the fee for landlord & property tax is the same in London as anywhere else in the country, and why there is nothing to visit and nothing to print.
