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
Companies House has tightened its requirements under the Economic Crime and Corporate Transparency Act: every company needs a registered email address and an appropriate registered office, every statement includes a lawful-purpose declaration, and every director and PSC must verify their identity. The confirmation statement, due annually with a £50 fee, is where most of this is confirmed.
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
Four dates govern Self Assessment: 5 October to register, 31 October for paper returns, 31 January to file online and pay, and 31 July for the second payment on account. Missing the January date triggers an automatic £100 penalty before any tax is even considered, so we treat it as the fixed point around which the rest of the year is planned.
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
Since April 2023 there have been two Corporation Tax rates, 19% small profits and 25% main, with marginal relief smoothing the transition between £50,000 and £250,000 of profit. The band is where planning matters: each pound of profit in it is taxed at an effective 26.5%, so pension contributions and capital expenditure timed to keep profit below £50,000 are worth more than they look.
Questions
HMRC Investigation Support questions from Headstone North
Will my previous accountant's errors be held against me?
The law holds you responsible for your return, but relying on a competent adviser and giving them full information is a reasonable excuse for many penalties. We establish what happened and present it to HMRC. If the adviser was negligent you may have a claim against them, which we help you document.
What if I disagree with HMRC's conclusion?
You can request a statutory review by an officer not involved in the case, which overturns or varies around a third of decisions, and you can appeal to the First-tier Tribunal within 30 days. We advise on the merits honestly and handle both routes; the £249 penalty appeal fee covers a review request or appeal against a penalty decision.
Do I have to attend a meeting with HMRC?
No. You are not obliged to attend a meeting and we often recommend written correspondence instead, which gives considered answers rather than off-the-cuff ones. Where a meeting is useful we attend with you or on your behalf, agree the agenda in advance and take our own notes of what was said.
Can HMRC go back more than one year?
The normal time limit is four years from the end of the tax year, extended to six for careless behaviour and twenty for deliberate behaviour or failure to notify. If HMRC finds an error in one year it will usually ask about others. Part of our job is holding HMRC to the correct time limit for the behaviour actually shown.
What is a voluntary disclosure and should I make one?
Telling HMRC about an error before it asks. Unprompted disclosures attract much lower penalties, often nil for careless errors, and are the right course when you know a return was wrong. The Digital Disclosure Service, Let Property Campaign and Worldwide Disclosure Facility are the main routes. Our fee from £599 covers preparing and negotiating the disclosure.
What penalties can HMRC charge?
For an inaccurate return, 0% to 30% of the extra tax for careless errors, 20% to 70% for deliberate ones and 30% to 100% for deliberate and concealed, with higher ranges for offshore matters. Within each range the penalty depends on whether the disclosure was prompted and how much you help. We work to secure the lowest point in the applicable range and suspension where available.
