GP Partnership Accounts and SA800 Tax Returns: 2025/26 UK Guide

GP partnership accounts help medical practices calculate their financial results, allocate profits between partners and prepare accurate tax returns. For the 2025/26 tax year, most GP partnerships required to submit an online SA800 return must file it by 31 January 2027.

Unlike salaried GPs, GP partners usually pay tax on their allocated share of partnership profits, not simply on the money they withdraw from the practice.

Understanding this difference is essential for avoiding tax surprises, preparing NHS pension records and managing practice cash flow.

This guide explains how GP partnership accounting works in the UK, what the SA800 involves, how profits are shared, the main filing deadlines and when specialist GP accounting support may be useful.

GP Partnership Accounts and SA800: Quick Answers

These answers apply to ordinary UK GP partnership arrangements. Particular structures, late HMRC notices, non-individual partners and other special circumstances can change the reporting requirements.

1. What Are GP Partnership Accounts?

GP partnership accounts are financial statements prepared for a medical practice operating as a partnership.

They record the practice's income, allowable business expenses, assets, liabilities and financial results for an accounting period.

Unlike a limited company, a traditional unincorporated GP partnership is generally not charged Corporation Tax on its trading profits. Instead, profits are calculated at partnership level and allocated to the partners for their own tax purposes.

The accounts provide a starting point for preparing the partnership tax return.

What Should GP Partnership Accounts Include?

A typical set of GP practice partnership accounts may contain:

• Profit and loss account.

• Balance sheet.

• NHS contract income analysis.

• Private medical income.

• Payroll and employment costs.

• Locum GP expenditure.

• Practice premises expenses.

• Partner capital and current accounts.

• Partners' drawings.

• Profit allocation statements.

• Relevant year-end adjustments.

Depending on the practice, additional schedules may be needed for pension deductions, dispensing activity, PCN arrangements, shared costs or other income streams.

Accurate bookkeeping for healthcare practices is important because errors in the monthly records can affect the final partnership accounts and profit allocations.

2. What Is an SA800 Partnership Tax Return?

An SA800 is the Self Assessment Partnership Tax Return used to report a partnership's income, expenses and taxable profit calculations to HMRC.

It also includes partnership statements showing how relevant income and profits are allocated between partners.

The SA800 is different from a partner's individual Self Assessment return.

SA800 vs SA104: What Is the Difference?

For example, a GP partnership with three partners will ordinarily prepare one partnership tax return and supply the relevant partnership statement information to each partner.

The partners then use their allocated figures when completing their own returns.

A specialist accountant can help ensure the partnership figures and individual returns agree.

For support with individual tax reporting, see Kudos Accounting's personal tax services.

3. GP Partnership SA800 Deadlines for 2025/26

The UK tax year 2025/26 runs from 6 April 2025 to 5 April 2026.

For most standard partnership Self Assessment filings, the relevant deadlines are:

Special rules may apply where HMRC issues a notice to file late or a partnership includes a company as a partner.

The online partnership return generally requires commercial tax software rather than the standard HMRC personal tax filing interface.

Official reference: HMRC Partnership Tax Return SA800.

What Happens if a GP Partnership Files Late?

A late partnership return can expose the partners to penalties even if they have submitted their personal tax returns.

HMRC may also charge interest and penalties on late personal tax payments.

Preparing the partnership accounts well before January gives partners more time to check profit allocations, review their personal liabilities and plan payments.

4. How Are GP Partnership Profits Calculated?

GP partnership taxable profits start with the practice's financial results, followed by the adjustments required by tax law.

The calculation can involve:

1. Recording all relevant partnership income.

2. Deducting business expenses in the accounts.

3. Making adjustments for expenses that are not deductible for tax.

4. Applying eligible capital allowances and other tax adjustments.

5. Calculating the partnership's taxable profits.

6. Allocating those profits between partners under the relevant agreement and tax rules.

The allocation should reflect the partnership's actual arrangements, including any applicable fixed profit entitlements and other agreed adjustments.

This is important because partners do not necessarily have equal profit shares.

GP Partnership Profit-Sharing Example

Consider a hypothetical practice with three GP partners.

After the relevant tax adjustments, assume the partnership has £300,000 of taxable profits to allocate.

The partners have agreed to the following profit-sharing percentages.

This simplified example is illustrative only. It assumes the stated percentages apply to the full taxable profit and excludes individual adjustments, basis-period issues and other personal income.

Partner A received £110,000 in drawings but has a £150,000 allocated profit share.

Partner B withdrew £95,000 but has a £90,000 allocated profit share.

This illustrates why drawings and taxable profits are different.

Partners must plan their tax payments around their taxable profit position rather than assuming that the amount transferred to their personal bank account determines the tax bill.

5. GP Partner Drawings vs Profit: Why It Matters

One of the most common misunderstandings in GP practice accounting concerns partners' drawings.

A partner may receive regular monthly transfers from the practice.

These payments are normally recorded against that partner's account rather than treated as employee wages.

For example, a partner might withdraw £7,000 per month, totalling £84,000 during the year.

However, their final taxable profit share might be £105,000.

The partner's Income Tax and applicable National Insurance calculations are generally based on the relevant taxable profit and personal tax position, not just the £84,000 withdrawn.

This can create an unexpected tax liability if the practice has not reserved enough money.

How Can GP Partners Avoid Tax Surprises?

GP partnerships should consider:

• Maintaining accurate monthly partner accounts.

• Reviewing provisional profit allocations.

• Estimating personal tax liabilities during the year.

• Monitoring drawings against projected profits.

• Keeping money available for tax payments.

• Reviewing changes when partners join or leave.

Where appropriate, specialist GP accountants can help partners connect practice profits with their individual tax planning.

6. Which NHS Income Streams Should GP Partnership Accounts Track?

GP practices often receive several different types of income.

Correct classification makes partnership accounts more reliable and helps the practice understand how funding changes affect its finances.

The treatment of particular receipts can depend on the practice's contracts and whether funds belong to the partnership or another legal entity.

Why NHS Income Reconciliation Matters

A GP partnership may receive a bank payment that does not match the expected gross contract amount because of deductions, adjustments or other transactions.

Recording only the net bank receipt without reviewing the underlying statement could hide missing income or misclassify costs.

Regular reconciliation helps practices prepare more accurate management accounts and year-end partnership accounts.

7. Which Expenses Can GP Partnerships Claim?

GP practices incur a wide range of costs while providing healthcare services.

Many genuine business expenses may be deductible when calculating taxable profits, subject to the relevant tax rules.

Examples can include:

• Salaried GP and practice staff employment costs.

• Locum fees.

• Practice rent and eligible premises costs.

• Utilities and insurance.

• Relevant professional subscriptions.

• Medical supplies.

• Accounting and software costs.

• Eligible staff training.

• Repairs and maintenance.

• Other costs incurred wholly and exclusively for the partnership's trade, subject to statutory rules.

However, not every accounting expense receives the same tax treatment.

Some costs require adjustment, while qualifying capital expenditure may receive capital allowances instead of a direct revenue deduction.

What About Expenses Paid Personally by a GP Partner?

Sometimes a GP partner incurs an expense on behalf of the practice.

The correct tax treatment depends on the nature of the expenditure and the partnership agreement.

HMRC's HS231 Doctors' Expenses guidance explains specific treatment for expenses and allowances relating to medical partnerships.

Where applicable, the relevant adjustments should be handled consistently in the partnership calculation and profit allocation, rather than being claimed twice.

Official reference: HMRC HS231: Doctors' Expenses.

8. How Do NHS Pension Contributions Affect GP Partnership Accounts?

NHS pension calculations are particularly important for GP partners because taxable partnership income and NHS pensionable earnings are not always the same.

A GP partner may be treated as a Type 1 medical practitioner for NHS Pension Scheme purposes.

Depending on their circumstances, they may need an annual certificate of pensionable profits, along with relevant pension estimates and reconciliations.

Important Records for NHS Pension Calculations

A GP partnership accountant may need to review:

• Partnership profit allocations.

• NHS pensionable and non-pensionable income.

• Relevant expenses.

• Pension contributions and deductions.

• NHS pension statements.

• Previous estimates and annual certificates.

• Any additional GP practitioner income relevant to the pension calculation.

Errors or omissions can affect contribution reconciliation and pension reporting.

GP partners should also consider separate tax issues such as the pension annual allowance, where relevant to their individual circumstances.

These matters are not determined simply by the total amount deducted from the practice bank account.

Kudos Accounting offers NHS pension accounting support for doctors and GPs where partnership accounts, pension records and personal tax reporting need to be reviewed together.

9. Does Making Tax Digital Apply to GP Partnerships in 2026?

Making Tax Digital for Income Tax began applying to certain qualifying individuals from 6 April 2026.

However, ordinary partnership profit shares are not currently included in the qualifying-income calculation for MTD for Income Tax.

The partnership's activities are also not currently subject to MTD Income Tax quarterly reporting.

HMRC has stated that a future timetable for bringing partnerships into the regime will be announced.

What If a GP Partner Also Has Private or Property Income?

A GP partner may separately operate a sole-trader business, provide self-employed medical services or receive relevant property income.

That separate income can create an MTD obligation when the applicable qualifying-income threshold is exceeded.

For example, the following situations require different treatment:

A GP partner who uses MTD software for other income must still report their partnership income in the relevant annual tax return.

Official reference: HMRC MTD qualifying-income guidance.

10. How Does Basis Period Reform Affect GP Partners?

The tax-year basis applies to trading income from the 2024/25 tax year onwards.

Where a GP partnership has an accounting year end that does not align with the tax year, the taxable profit calculation may require figures from more than one accounting period.

Partnerships with year ends between 31 March and 4 April may qualify for the late-accounting-date rules that simplify this calculation.

Some partners may also have remaining transition profits from the 2023/24 basis period reform.

Under the usual spreading arrangements, a proportion of those transition profits can still be taxable in 2025/26.

This means a partner's final taxable income may not simply equal the profit figure shown for one set of annual practice accounts.

Why This Needs Specialist Review

A GP partner may have:

• Profits from the current tax-year calculation.

• Remaining transition profits.

• Personal medical income from other sources.

• Eligible pension adjustments.

• Payments on account or earlier tax liabilities.

These items should be reviewed together before the individual Self Assessment return is completed.

11. What Documents Should You Give Your GP Partnership Accountant?

Preparing financial records early can reduce delays and improve the accuracy of the SA800 process.

The following checklist is useful for a GP practice manager or nominated partner.

Practices with several partners should confirm that records are complete before the final tax figures are approved.

12. When Should a GP Partnership Hire a Specialist Accountant?

A general accountant may understand partnership taxation but may not be familiar with every aspect of NHS practice income, pension administration and GP-specific financial reporting.

Specialist support can be particularly useful when:

• Several partners have different profit shares.

• NHS payments and deductions are difficult to reconcile.

• Partners have unexpectedly high tax bills.

• NHS pension records do not reconcile with accounts.

• The practice has locum, salaried and partnership income arrangements.

• Partners are joining, retiring or leaving the practice.

• The existing accountant is slow to prepare year-end accounts.

• The practice needs clearer financial information during the year.

What Should You Ask Before Choosing a GP Partnership Accountant?

For practices reviewing their current adviser, the goal should be to find someone who understands both partnership tax reporting and the financial structure of a GP practice.
