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
Payments on account catch out most people in their second year of self-employment. HMRC assumes next year's tax will match this year's and collects half in January and half in July, in advance, on top of the balancing payment. If profits are dropping you can apply to reduce them, but reducing them too far attracts interest. We calculate the right figure rather than guessing.
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
HMRC's penalties for a late Self Assessment return are automatic: £100 the day after 31 January, £10 a day from three months late up to £900, then the greater of £300 or 5% of the tax at six and twelve months. Interest and separate late-payment penalties apply to the tax itself. Companies House charges £150 to £1,500 for late accounts, doubling for a second consecutive year.
Corporation Tax rates and marginal relief
Companies pay Corporation Tax at 19% on profits up to £50,000 and 25% on profits over £250,000. Between those figures marginal relief applies, producing an effective rate that rises gradually and a marginal rate of 26.5% on each pound in the band. The thresholds are divided by the number of associated companies, so a director with two companies has thresholds of £25,000 and £125,000 for each.
Questions
HMRC Investigation Support questions from Hatfield
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.
