GP practice accounting sits apart from ordinary small-business bookkeeping. The income arrives through NHS contracts that no other sector uses, the profit is split between partners under an agreement rather than paid as wages, and the NHS pension is woven through the accounts before anyone takes a penny home. Get the structure right and the tax, the pension and the partner relationships all run smoothly. Get it wrong and partners pay tax on the wrong figure, miss pension deadlines or fall out over who earned what.

This guide explains how GP practice accounts actually work: the partnership and SA800 structure, the difference between drawings and profit share, the NHS income streams, how superannuation lands on the accounts, allowable expenses, the year-end and tax cycle, Making Tax Digital, and when a specialist medical accountant earns their place. It is general information, not personal tax advice.

How GP Practice Accounting Works

Most GP practices in England operate as a traditional partnership, where two or more GP partners run the practice jointly and share the profit. A minority use a limited liability partnership (LLP), and some single-handed practices run as a sole trader. A limited company cannot hold a GMS or PMS contract, so the company route is not available for core NHS general practice (it is only relevant to private or non-NHS work).

A partnership is transparent for tax. The partnership itself does not pay tax. Instead, the practice profit is calculated once, then allocated to the partners, and each partner pays their own income tax and National Insurance on their share. That single feature drives almost everything else in GP accounting.

The practice accounts pull together:

  • all practice income (NHS contract income, enhanced services, PCN funding, dispensing income where relevant, and any private work);
  • all allowable practice expenses (staff costs, premises, locum cover, equipment, indemnity, professional fees);
  • the superannuation deducted through PCSE before the profit is distributed;
  • the resulting profit, and how it is split between the partners under the partnership agreement.

From those accounts flow the partnership tax return, each partner's personal tax position, and the pensionable-profit certificates. For the deeper tax mechanics, see our complete guide to GP partnership tax.

The Partnership and the SA800 Return

A GP partnership does not file accounts at Companies House (it is not a limited company). Its tax obligations run on two levels:

  • The partnership return (SA800). The practice files one partnership return each year showing total income, total allowable expenses, the overall profit, and how that profit is divided between the partners. The SA800 itself does not generate a tax bill: it allocates.
  • Each partner's personal return. Every partner reports their allocated share on the partnership pages (SA104) of their own Self Assessment return, where it is taxed as trading income with Class 4 National Insurance. Our guide to the GP tax return walks through the partner's personal filing in detail.

The partnership agreement is the spine of the accounts. It sets out how profit is shared, how a new partner buys in, how a leaving partner is paid out, how premises are held, and how decisions are made. A clear, current agreement prevents most partner disputes; an out-of-date one causes them.

Drawings Versus Profit Share

This is the single most misunderstood point in GP accounting, so it is worth stating plainly. A GP partner is taxed on their profit share, not on their drawings.

  • Drawings are the regular amounts (usually monthly) that a partner takes out of the practice bank account during the year. They are set at a prudent level against the profit the practice expects to make.
  • Profit share is the partner's actual entitlement to the year's profit, fixed at the year end under the partnership agreement.

During the year, drawings are payments on account against the eventual share. At the year end the accountant works out each partner's true profit share and reconciles it against what they actually drew. A partner who drew more than their share repays the difference (or it sits as a debit on their current account); a partner who drew less is owed the balance. Because tax is charged on the share, not the cash taken, partners need to set drawings sensibly and keep a tax reserve so they are not caught short when the January and July payments fall due.

NHS Income Streams in the Accounts

NHS general practice is funded through one of three contract types: GMS (General Medical Services, nationally negotiated and governed by the Statement of Financial Entitlements), PMS (Personal Medical Services, locally agreed) and APMS (Alternative Provider Medical Services). Whichever contract applies, the income reaching the accounts breaks down into recognisable streams:

  • Global Sum. The core per-patient payment, weighted by the Carr-Hill formula, which adjusts the registered list for age, sex, morbidity, list turnover and geography to produce weighted patients. There is no single national per-patient value: it is weighted and uplifted each year, so the figure in your accounts is practice-specific.
  • QOF (Quality and Outcomes Framework). A voluntary, points-based quality scheme. Achievement is measured across the year and the point value is uprated annually, so QOF income is typically accrued at the year end rather than recognised purely on receipt.
  • Enhanced services. Payments for additional services the practice agrees to provide (national or local).
  • PCN and Network Contract DES funding. Income flowing through the Primary Care Network, including the Additional Roles Reimbursement Scheme (ARRS), which reimburses the cost of additional roles such as clinical pharmacists and physiotherapists.
  • Dispensing income. For dispensing practices, the margin and fees on dispensed medicines, which can be a substantial and distinct income stream.

Note these are NHS general-practice concepts. GP practices are not funded by UDAs or activity bands (those belong to NHS dentistry and have no place in a GP set of accounts). Because so much of the income is weighted, accrued and uplifted annually, good year-end accruals are central to a fair set of GP accounts.

Superannuation and the NHS Pension on the Accounts

Pension is not an afterthought in GP accounting; it runs through the income before the profit is struck. Employer and employee superannuation contributions are deducted from the practice's NHS income through PCSE, so the cash the practice receives is already net of pension. The accounts then need to present this correctly so each partner's pensionable position is clear.

For pension certification, the roles map as follows:

  • Type 1 medical practitioners (GP partners) complete the Annual Certificate of Pensionable Profits each year, certifying pensionable NHS profit.
  • Type 2 medical practitioners (salaried GPs and solo GP work) complete the Type 2 self-assessment form, usually submitted a year in arrears.
  • Freelance GP locums pension their income through Locum forms A and B.

All active members now accrue in the 2015 (CARE) section of the NHS Pension Scheme. The point where the accounts feed straight into tax planning is the annual allowance: high practice profits drive a larger pension input amount, and a high-earning GP can breach the allowance or hit the taper and face a tax charge. This is a frequent issue for GP partners, so the accounts should track pensionable profit with the allowance in mind. Our complete guide to the NHS pension annual allowance explains the £60,000 allowance, the taper and how to manage a charge.

Allowable Expenses

GP accounting must capture every legitimate practice expense to arrive at the right profit and the right tax. Expenses must be incurred wholly and exclusively for the practice. Common allowable costs include:

  • staff salaries, employer pension and employer National Insurance;
  • premises costs (rent or notional/cost rent, rates, utilities, maintenance);
  • locum cover for leave, sickness and training;
  • the GMC annual retention fee, Royal College and specialty membership, and BMA subscription (List 3 items);
  • medical indemnity (MDU, MPS or MDDUS), noting that NHS GP clinical negligence is covered by the state CNSGP scheme, so a GP's own paid indemnity is largely for private, non-clinical and regulatory matters;
  • continuing professional development relevant to current practice;
  • equipment and IT (usually relieved through capital allowances and the Annual Investment Allowance);
  • business mileage between sites and on home visits (HMRC approved mileage is 55p per mile for the first 10,000 business miles and 25p thereafter for 2026/27; ordinary home-to-base commuting is not allowable);
  • accountancy fees, business bank charges and business-loan interest.

Year-End, Tax and Payments on Account

Once the year-end accounts and SA800 are finalised, each partner's profit share flows onto their personal return and is taxed at their marginal rate (20%, 40% or 45%) alongside Class 4 National Insurance.

  • Class 4 National Insurance is charged at 6% on profits between £12,570 and £50,270, then 2% above £50,270.
  • Class 2 National Insurance is no longer a required payment for the self-employed with profits at or above the small-profits threshold (treated as paid to protect the state-pension record), a change in effect since 6 April 2024. There is no weekly Class 2 charge to budget for.
  • Payments on account. Where a partner's prior-year liability exceeded £1,000 and less than 80% was collected at source, HMRC requires two interim payments, each 50% of the prior year's bill, due 31 January and 31 July, with any balance settled the following 31 January. New partners in particular should plan for the first January payment, which can include a balancing payment and the first payment on account together.

Because partners pay tax personally and only twice a year, a disciplined tax reserve out of drawings is essential. The accounts and the partnership cash flow should make clear how much each partner needs to hold back.

Making Tax Digital for GP Practices

Making Tax Digital for Income Tax (MTD for ITSA) introduces digital records and quarterly updates for sole traders and landlords by qualifying income. The thresholds are £50,000 from 6 April 2026, £30,000 from 6 April 2027 and £20,000 from 6 April 2028, tested on the relevant prior year's return.

For a GP practice, the headline is reassuring at partnership level but not at partner level:

  • General partnerships are deferred with no confirmed start date, so a GP partnership is not mandated into MTD for Income Tax in April 2026.
  • Individual partners may still be in scope on their personal return if they have other self-employed income (for example private clinics, expert-witness work or locum sessions) above the qualifying-income thresholds.
  • Limited companies are out of MTD for ITSA entirely (it is an income-tax regime), so a locum trading through a personal service company is not affected.

The old £10,000 threshold that circulated in early guidance no longer applies; the entry point is £50,000 from April 2026. Practices should nonetheless move to good digital record-keeping now, because partners with private or locum income on top of their NHS profit will be among the first caught.

When to Use a Specialist Medical Accountant

GP accounting is full of NHS-specific machinery that general practice accountants rarely see. A specialist medical accountant understands:

  • NHS contract income and how Global Sum, QOF, enhanced services, PCN and dispensing income flow and accrue;
  • profit allocation between partners and the reconciliation of drawings to profit share;
  • superannuation and the Type 1 Annual Certificate, Type 2 self-assessment and locum certification;
  • the NHS pension annual allowance and taper that catch high-earning GPs;
  • premises arrangements such as notional rent, cost rent and the last-man-standing risk, often held in a separate property partnership;
  • VAT, which for general practice is mostly outside the scope or exempt but bites on private and certain non-clinical work (see our guide to GP VAT registration).

These are precisely the areas where a non-specialist most often gets a GP practice wrong, costing partners tax, pension or partnership goodwill.
