GP Tax & Accounts

GP Tax Return Essentials

Every GP with self-employed income must file a Self Assessment tax return by 31 January following the end of the tax year. For GP partners, this includes reporting their share of partnership profits on the partnership pages (SA800) and their personal return (SA100). Salaried GPs who only receive PAYE income may not need to file — but those with locum sessions, private work or investment income above £1,000 almost certainly will.

Getting the return right depends on accurate partnership accounts and correctly allocated income. Common errors include misreporting superannuation contributions (which are not deducted from taxable profits but are relieved via the pension scheme), failing to include seniority payments or Golden Hello retention payments, and not claiming overlap relief when a GP retires or leaves a practice mid-year. These mistakes can trigger HMRC enquiries and result in penalties plus interest on underpaid tax.

Income Sources and Reporting

A GP's taxable income can come from a surprisingly wide range of sources. Each must be reported correctly, and some have specific rules that differ from standard self-employment income.

• NHS partnership profits — the GP's share of practice profits after allowable expenses
• Salaried GP income — taxed via PAYE, but additional income may require Self Assessment
• Locum fees — typically self-employed income requiring registration and Class 2/4 NICs
• Private and medico-legal work — insurance reports, cremation fees, occupational health contracts
• NHS Pension Scheme employer contributions — not taxable income but affect annual allowance calculations
• Property income from surgery premises — rent received from the practice or third parties
• Training grants, bursaries and clinical excellence awards

Tax Efficiency Strategies for GPs

Tax planning for GPs goes beyond claiming allowable expenses. While practice costs, professional subscriptions (BMA, MDU/MPS, RCGP), training courses and business mileage are all deductible, genuine tax efficiency requires a more strategic approach. Pension contributions remain one of the most powerful tools — NHS Pension Scheme contributions attract full income tax relief, and additional voluntary contributions or personal pensions can shelter further income.

For higher-earning GPs, the tapered annual allowance means pension contributions above the threshold trigger tax charges. Understanding where you sit relative to the adjusted income thresholds is critical — a small reduction in taxable income can sometimes restore thousands of pounds of annual allowance. Other strategies include timing capital expenditure to maximise capital allowances, using the marriage allowance or spousal employment where appropriate, and structuring private work through a limited company when volumes justify the administrative overhead.

Partnership Taxation

GP partnerships are transparent for tax purposes — the partnership itself does not pay tax, but each partner is taxed on their allocated share of profits. The partnership must file a partnership return (SA800) showing total income and expenses, and each partner reports their share on their personal return. Profit allocation follows the partnership agreement, which may include prior shares, seniority adjustments and different splits for different income streams.

Complications arise when partners join or leave mid-year, when profit-sharing ratios change or when the practice has a different accounting year end from the standard 5 April tax year. The basis period reform that took effect from 2024/25 means all partnerships are now taxed on a tax-year basis, eliminating overlap profits going forward but requiring transitional adjustments for existing practices. GPs who accumulated overlap relief over many years should ensure this is being correctly unwound in their returns.

Payment on Account and the Tax Planning Calendar

Self-employed GPs make payments on account — two advance payments towards the current year's tax bill, each equal to half of the previous year's liability. These fall on 31 January and 31 July. If income has fallen significantly (for example, due to reduced sessions or a change in partnership share), GPs can apply to reduce payments on account — but must be careful, as underestimating triggers interest charges.

• April–May: Review the previous tax year, gather income records and commission partnership accounts
• June–September: Finalise partnership accounts, prepare superannuation certificates and draft personal returns
• October–December: Submit Self Assessment return, review current-year estimates and plan pension contributions
• January: Pay balancing payment and first payment on account for the new tax year
• July: Make second payment on account — consider reducing if income has dropped
