Worth knowing
Rules that come up in this work
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
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
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
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.
The VAT registration threshold
The £90,000 VAT threshold is measured over any twelve consecutive months, which is why a strong quarter can tip a business over unexpectedly. Registration must follow within thirty days of the end of the month the threshold was crossed. Below the threshold, voluntary registration is worth considering when customers are VAT-registered businesses and costs carry VAT.
Director's loan accounts
A director's loan account records money moving between a director and the company that is not salary or dividend. If the director owes the company money nine months and one day after the year end, the company pays section 455 tax at 35.75% of the balance, refundable only when the loan is repaid. Loans over £10,000 are also a benefit in kind unless interest is charged at HMRC's official rate.
Questions
Locum Accountants questions from Northwood
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.
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.
What expenses can locums claim?
Professional indemnity insurance, registration fees to the GMC, GDC, GPhC or equivalent, exam fees and courses that maintain skills, medical equipment, professional subscriptions and journals, travel between placements (not ordinary commuting to a regular workplace), a proportion of home costs for administration, and accountancy. We review each category.
What is the annual allowance and does it affect me?
The annual allowance limits tax-relieved pension growth to £60,000 a year, tapering down to £10,000 for those with adjusted income over £260,000 and threshold income over £200,000. NHS pension growth is measured on the increase in the promised pension, which can be large in a high-earning year. We check it and report any charge or scheme pays election.
