Yes, Members of Parliament do pay tax. An MP’s salary is subject to income tax and National Insurance through PAYE at exactly the same rates that apply to any other UK employee, with no parliamentary exemptions, secret rebates, or special carve-outs. As of April 2025, the basic MP salary is £93,904, and tax is deducted from each monthly payment before it lands in their account.1UK Parliament. Pay and Expenses for MPs
How the Salary Is Taxed
The Independent Parliamentary Standards Authority acts as the employer for payroll purposes. IPSA deducts income tax and National Insurance at source through HMRC’s Pay As You Earn system and pays the net amount to each MP.2Independent Parliamentary Standards Authority. Calculation of Salaries and Tax Arrangements for MPs and Their Staff The process is identical to how any salaried worker in the country gets paid.
For MPs in England, Wales, and Northern Ireland, the standard UK income tax bands apply:3GOV.UK. Income Tax Rates and Personal Allowances
- Personal allowance: the first £12,570 is tax-free
- Basic rate (20%): £12,571 to £50,270
- Higher rate (40%): £50,271 to £125,140
- Additional rate (45%): above £125,140
On a salary of £93,904 with no other income, an MP sits in the higher-rate band. Class 1 National Insurance is deducted alongside income tax. For the 2025/26 tax year, employees pay 8% on weekly earnings between £242 and £967, then 2% on anything above that.4GOV.UK. National Insurance Rates and Categories – Contribution Rates
One quirk catches MPs with side income. The personal allowance starts tapering once total income exceeds £100,000 and disappears completely at £125,140.3GOV.UK. Income Tax Rates and Personal Allowances An MP on the basic salary alone stays under the threshold, but add a consultancy fee, a book advance, or rental income, and part or all of the tax-free allowance vanishes. The effective marginal tax rate on income between £100,000 and £125,140 hits 60%.
Scottish MPs Pay Scottish Rates
MPs classed as Scottish taxpayers face different income tax bands set by the Scottish Parliament, even though they sit at Westminster. Scotland uses six rates rather than three, and they are generally steeper at the upper end:5mygov.scot. Current Rates – 6 April 2025 to 5 April 2026
- Starter rate (19%): £12,571 to £15,397
- Basic rate (20%): £15,398 to £27,491
- Intermediate rate (21%): £27,492 to £43,662
- Higher rate (42%): £43,663 to £75,000
- Advanced rate (45%): £75,001 to £125,140
- Top rate (48%): above £125,140
A Scottish MP on the basic salary pays their top slice at 42% rather than the 40% their English colleague pays on the same income. That amounts to a few hundred pounds a year on salary alone, and the gap widens with outside earnings. National Insurance is a UK-wide system and applies at the same rates wherever the MP lives.
Are Expenses and Allowances Taxed?
Most public confusion about MPs and tax lives here. MPs can claim significant sums for running their offices, paying staff, travelling between Westminster and their constituencies, and renting a second home. Those costs are paid by IPSA rather than out of the MP’s salary, and when they genuinely relate to parliamentary work they are not treated as taxable income.
The legal basis sits in the Income Tax (Earnings and Pensions) Act 2003. Section 336 makes employment expenses deductible when they are incurred wholly, exclusively, and necessarily in performing the job.6Legislation.gov.uk. Income Tax (Earnings and Pensions) Act 2003, Section 336 Separate provisions in the same Act specifically exempt MP travel for parliamentary duties and certain accommodation costs for members who need a second home near Westminster.
IPSA’s own rules cap each category of spending and require evidence within 90 days. Anything spent on party-political work, campaigning, or personal purposes is excluded from what MPs can claim.7Independent Parliamentary Standards Authority. The Scheme of MPs’ Staffing and Business Costs 2024-25 If a reimbursement provides a personal benefit rather than covering a genuine work cost, it gets reclassified as a taxable benefit-in-kind. A train ticket to a constituency surgery is a work expense. A family holiday billed to the office budget is taxable income, and HMRC treats it as such.
Tax on Outside Earnings
Plenty of MPs earn money beyond their parliamentary salary through directorships, legal work, media appearances, or property. None of it is tax-exempt. MPs are specifically required to file a Self Assessment tax return each year, whether or not they have outside income.8HM Revenue and Customs. Tax and National Insurance Contributions Guide for MPs and Ministers The return pulls all income sources together to work out the total liability for the year.
Outside earnings are also disclosed publicly through the Register of Members’ Financial Interests, which records anything that could reasonably be seen as influencing an MP’s actions or votes.9UK Parliament. Register of Members’ Financial Interests The register is an ethics mechanism rather than a tax tool, but it creates a public paper trail that makes underreporting to HMRC especially risky.
Investment income follows the same logic. Dividends above the £500 tax-free allowance are taxed at rates ranging from 8.75% for basic-rate taxpayers up to 39.35% for additional-rate taxpayers. Capital gains on property or shares are taxed at 18% or 24% depending on the MP’s income band.10GOV.UK. Capital Gains Tax – What You Pay It On, Rates and Allowances An MP selling a buy-to-let flat faces the same CGT bill as any other landlord doing the same thing.
The online Self Assessment deadline for each tax year is 31 January of the following year, and any tax owed must be paid by the same date.11GOV.UK. Self Assessment Tax Returns – Deadlines Missing it triggers an automatic £100 penalty even if no tax is due.
Pension Contributions
MPs belong to the Parliamentary Contributory Pension Fund, a defined-benefit scheme where costs are shared between members and the taxpayer.12GOV.UK. About the Parliamentary Contributory Pension Fund Contributions receive tax relief in the same way as any other workplace pension: they are taken before income tax is calculated, reducing the MP’s tax bill in the year the contribution is made.
The standard annual allowance for pension contributions is £60,000 for 2025/26, and MPs with substantial outside earnings can see that allowance tapered down.13GOV.UK. Pension Schemes Rates Once an MP retires and starts drawing pension income, that income is taxed through PAYE at whatever rate applies to their total retirement income, exactly as it would be for any other pensioner.14UK Parliament. MPs’ Pensions
Tax When Leaving Parliament
MPs who lose their seats at a general election can receive a loss-of-office payment from IPSA, provided they stood for re-election and had served at least two continuous years. The amount is double the statutory redundancy entitlement, calculated on years of service and age.15Independent Parliamentary Standards Authority. The Scheme of MPs’ Staffing and Business Costs 2025-26
Under Section 403 of the Income Tax (Earnings and Pensions) Act 2003, the first £30,000 of a termination payment is free of income tax.16Legislation.gov.uk. Income Tax (Earnings and Pensions) Act 2003 – Section 403 Anything above that is taxed at the MP’s marginal rate and added to their taxable income for the year they receive it. IPSA handles the deductions before the money arrives.
What Happens When MPs Get It Wrong
MPs face the same enforcement regime as anyone else. Missing the Self Assessment deadline triggers an immediate £100 fine, followed by daily penalties of £10 (up to £900) after three months, then 5% of the tax owed or £300 (whichever is higher) at both the six-month and twelve-month marks.17GOV.UK. Self Assessment Tax Returns – Penalties The penalties apply whether the underlying tax bill is £50 or £50,000.
HMRC also runs a dedicated compliance team for high earners and individuals with complex tax affairs. Anyone earning above £200,000 or holding assets over £2 million is classified as a wealthy individual and managed separately, with around 910 specialist staff assigned to that group. In 2023/24, that work produced 25 criminal prosecutions. An MP with substantial outside interests sits squarely in this category, and the fact that their declared earnings are already public in the Register of Members’ Financial Interests makes underreporting to HMRC a poor gamble.
