Worth knowing
Rules that come up in this work
CIS deductions
Under the Construction Industry Scheme, contractors deduct 20% from a registered subcontractor's labour invoices, or 30% if unregistered, and pay it to HMRC. The subcontractor reclaims the deductions against their actual tax through Self Assessment, usually producing a refund because deductions are on turnover while tax is on profit. Contractors file a monthly return by the 19th.
Confirmation statements and identity verification
The confirmation statement is the annual check that the public register is right: officers, registered office, SIC codes, shareholders and the PSC register. It carries a £50 fee and no financial penalty for lateness, but failure to file leads to compulsory strike-off. The identity verification regime introduced in November 2025 has added a further check to every statement.
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.
The Self Assessment calendar
Self Assessment runs on a fixed annual cycle. Registration by 5 October following the tax year, online filing and payment by 31 January, and a second instalment on 31 July for those making payments on account. The penalties for lateness are automatic and escalate monthly, which is why we file early and chase approvals well before the window closes.
Making Tax Digital for Income Tax
MTD for Income Tax replaces one annual return with quarterly digital updates and a year-end declaration, submitted from software. The threshold is gross trading and property income, measured two years earlier, and started at £50,000 in April 2026 before falling to £30,000 in April 2027. Anyone affected needs digital record keeping in place before their start date, not after.
Late filing penalties
Lateness is expensive in a way that compounds. For individuals, £100 immediately, then daily penalties, then percentage-based ones at six and twelve months, with interest running on unpaid tax throughout. For companies, Companies House penalties scale with delay and double on repeat, and HMRC adds its own for a late CT600. Filing on time is the cheapest tax planning there is.
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 Downham
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.
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.
What happened to furnished holiday lets?
The furnished holiday let regime ended on 5 April 2025. Holiday lets are now taxed like other residential lets: the finance-cost restriction applies, capital allowances on furniture are replaced by replacement relief, and the capital gains reliefs are withdrawn with transitional rules. Our £249 holiday let service handles the transition and the new treatment.
My partner and I own a property jointly. How is the income split?
Married couples and civil partners are taxed 50/50 by default regardless of actual ownership, unless you own in unequal shares and file Form 17 with evidence to be taxed on your actual shares. Unmarried joint owners are taxed on their actual shares. Choosing the right split can save tax where one of you is in a lower band.
