Local facts
About Cardiff
Cardiff is in Wales, in the CF10 postcode district, Wales. Welsh taxpayers pay Welsh rates of income tax, set by the Senedd and currently matching the English bands, collected under a C-prefixed tax code. National Insurance, VAT and Corporation Tax are UK-wide. Property purchases in Wales pay Land Transaction Tax to the Welsh Revenue Authority rather than Stamp Duty, with its own bands and rates.

Worth knowing
Rules that come up in this work
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.
CIS deductions
The Construction Industry Scheme affects both sides of a construction payment. Contractors must verify subcontractors, deduct the right amount, issue statements and file monthly, with penalties from £100 for each late return. Subcontractors suffer deductions on turnover and recover the excess at the year end. Limited company subcontractors offset deductions against PAYE monthly instead.
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.
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.
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 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 Cardiff
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.
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.
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.
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.
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.
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.
