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
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
A common surprise in Self Assessment is the January payment that is far larger than expected. That is the balancing payment for the year just ended plus the first payment on account for the year ahead, which HMRC sets at half of the bill just calculated. We put the figure in your hands months ahead and tell you how to adjust it legitimately when circumstances change.
The Self Assessment calendar
The tax year runs from 6 April to 5 April. Anyone new to Self Assessment must register by 5 October after the end of the tax year in which their untaxed income began. The online return and the balancing payment are due by 31 January, with a second payment on account on 31 July where they apply. Paper returns have an earlier deadline of 31 October and are rarely sensible.
Making Tax Digital for Income Tax
Making Tax Digital for Income Tax began in April 2026 for sole traders and landlords with qualifying income over £50,000, extends to those over £30,000 in April 2027 and is planned for £20,000 in April 2028. It requires digital records in compatible software and four quarterly updates to HMRC each year, with a final declaration replacing the traditional return. Payment dates are unchanged.
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
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
Locum Accountants questions from South Harefield
I do private work alongside NHS sessions. How is that treated?
Private practice income is self-employment, not pensionable in the NHS scheme, and taxed with your other self-employed income. If the private work is substantial it may suit a limited company while the NHS locum work stays as a sole trader, and we advise on running both structures together.
Can you handle the NHS pension estimate of earnings and the Type 2 form?
Yes. The estimate of pensionable earnings submitted at the start of each year sets your contribution rate; the Type 2 certificate reconciles the actual figures after the year end and is due by the end of February. Both are prepared from the records we keep and submitted on your behalf.
Do locum pharmacists and dentists have the same pension issues?
Dental associates and performers pension their NHS earnings through the dental pension arrangements with annual reconciliation statements; locum pharmacists generally have no NHS pension on locum income. Each profession has its own regime and we handle the specific paperwork for yours.
What is the annual-only option?
For £199 we prepare your Self Assessment from the records you keep yourself, including the reconciliation of your engagement income and pension contributions. It suits locums with a small number of regular engagements who are organised. If records are incomplete, the monthly package is usually better value.
How do you handle a mix of NHS employment and locum work?
Employment income is taxed through PAYE and shown on the employment pages; locum income is self-employment on the self-employment pages. The return brings them together and your marginal rate applies to the combined figure. Payments on account are often triggered by locum income on top of employment. We reconcile all sources.
Is travel between practices claimable?
For a locum working at many different sites, travel from home to each temporary place of work is generally allowable because there is no permanent workplace. For a regular session at the same practice over a long period, that site may become a permanent workplace and the travel ordinary commuting. We assess each engagement pattern.
