Worth knowing

Rules that come up in this work

Salary versus dividends

Directors of their own companies usually take a salary at or just above the National Insurance thresholds, which keeps the year qualifying for State Pension and is deductible for Corporation Tax, with further income as dividends. Dividends above the £500 allowance are taxed at 10.75%, 35.75% and 39.35% by band and can only be paid from distributable profits after tax, with a minute and voucher each time.

Director's loan accounts

The most common tax problem in owner-managed companies is an overdrawn director's loan account: drawings taken during the year that were never declared as dividends or salary. The company faces a 35.75% charge on the balance outstanding nine months after the year end, and the director may have a benefit in kind. We review the account before every year end to clear it properly.

The VAT registration threshold

Watching the rolling twelve-month turnover figure is one of the quiet jobs of monthly bookkeeping, because the £90,000 VAT threshold arrives silently. Crossing it brings quarterly returns, Making Tax Digital software and a decision about schemes. Crossing it late brings a bill for VAT you could not recover from customers and a penalty for failing to notify.

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.

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.

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.

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.

Questions

Locum Accountants questions from Trinity

Should a locum work through a limited company?

It depends on the work. GP locum income is pensionable in the NHS scheme only when earned as an individual, so incorporating loses pension accrual on that income. Private work and some agency work suit a company better. Off-payroll rules apply to engagements with NHS bodies through your company. We run the comparison for your mix of work.

How does the NHS pension work for a GP locum?

Locum GPs pension their income through Locum Forms A and B, submitted to the pensions agency within ten weeks of the work, with employee contributions deducted and employer contributions paid by the practice or ICB. A Type 2 certificate reconciles the year. Missing the ten-week window loses the pension on that income. We track it.

What does the £69 sole trader locum package include?

Monthly bookkeeping of all engagement income and expenses, reconciliation of pay statements and remittance advices, NHS pension contribution tracking, a monthly summary with the tax accruing, your Self Assessment with the self-employment and any employment pages prepared and filed, and payments on account calculated.

What does the £95 company package include?

Monthly bookkeeping, director payroll with RTI submissions, dividend paperwork, statutory accounts and CT600 filed, the confirmation statement filed (Companies House £50 fee separate), and deadline tracking. Your personal Self Assessment is added at the published £129 where needed, often necessary because of NHS employment income.

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.

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.
