State Pension and Simple Assessment 2027/28 — What Changes

From the 2027/28 tax year, the UK government plans to reduce the need for some pensioners to pay small amounts of tax through Simple Assessment. The published policy is aimed at people whose sole income is the basic or new State Pension without increments, where that State Pension exceeds the Personal Allowance.

This is an announced administrative change, not a general exemption from tax on State Pension income. HM Treasury says further detail will be set out later. A State Pension remains taxable income, and people with occupational pensions, private pensions, savings, dividends, employment income or other taxable income may still need tax collected through another route or may still receive a Simple Assessment.

Use the official State Pension forecast service to check your entitlement, and read the existing State Pension 2026/27 guide for the wider pension rules.

What is changing from 2027/28?

HM Treasury's Budget 2025 measure says the government will ease the administrative burden for pensioners whose only income is the basic or new State Pension without any increments, where the pension exceeds the Personal Allowance. The stated aim is that these people should not have to pay small amounts of tax through Simple Assessment from 2027/28.

The announcement is narrower than “pensioners will no longer pay tax”. It describes a change to the collection process for a defined income pattern. The government has said it is exploring how to achieve the change and will publish more detail. Until that detail is available, do not treat the announcement as a complete eligibility test or as a final replacement for the current HMRC process.

What is Simple Assessment now?

Simple Assessment is an HMRC calculation used when tax is owed but cannot be collected through a tax code and the person is not required to complete a Self Assessment tax return for that income. HMRC uses information it holds about income and tax already paid, then sends a tax calculation, normally called a PA302.

Under the current GOV.UK guidance, a person may receive a Simple Assessment if they owe tax that cannot be collected through PAYE, owe £3,000 or more, need to pay tax on State Pension income or have certain untaxed income such as savings interest or dividends.

Simple Assessment is not the same as Self Assessment. A person who receives a Simple Assessment letter should check the calculation and follow the payment instructions. The letter includes the amount due and a payment reference, and HMRC's current guidance says incorrect information should be raised with HMRC within the stated period.

The 2027/28 policy does not remove the need to read an HMRC letter. It may change whether a narrowly defined pensioner receives or pays a small Simple Assessment amount, but the final process still depends on official implementation guidance.

Why can the State Pension create a tax bill?

The State Pension is taxable, but tax is not deducted before the payment reaches the recipient. HMRC adds the taxable State Pension entitlement to other taxable income, deducts available allowances and applies the relevant Income Tax rates.

For a person with a State Pension above the Personal Allowance and no tax collected elsewhere, there may be a small amount of Income Tax due. HMRC may collect it through a tax code applied to another pension or employment income, or through Simple Assessment if it cannot be collected that way.

The tax calculation depends on the person's total taxable income, not merely the label on the payment. A person with a private pension, workplace pension, savings interest, dividends or taxable benefits should not assume that the 2027/28 administrative measure covers them.

Who appears closest to the announced policy?

The published wording points most directly to someone who:

1. receives the basic State Pension or new State Pension;
2. has no increments to that State Pension;
3. has no other income, so the State Pension is their sole income; and
4. has a State Pension amount above the Personal Allowance from the relevant point.

This is a description of the policy's stated target, not a final HMRC eligibility checklist. For example, the words “sole income” are important. An occupational pension, a private pension, savings interest, dividends, employment income or another taxable benefit can change how tax is calculated and collected.

Do not assume that a person is covered merely because they are above State Pension age or because their State Pension is higher than the Personal Allowance. The absence or presence of other income and increments matters.

Who may still need to deal with Simple Assessment?

The planned change should not be treated as covering people with more complex income. A pensioner may still need to check or pay a Simple Assessment where they have:

• an occupational or private pension in addition to State Pension;
• savings interest or dividends that create taxable income;
• employment or self-employed income;
• taxable benefits or another State Pension-related payment that changes the total;
• an underpayment that HMRC cannot collect through a tax code; or
• a Self Assessment obligation for a separate reason.

These examples do not create a new tax threshold. They explain why “sole income” is a key boundary in the announcement. HMRC's final guidance will determine how each income type is treated for 2027/28.

How is State Pension income valued for tax?

HMRC says that the taxable State Pension figure is based on the amount a person was entitled to receive for the tax year, rather than simply the payments received in the bank account. The State Pension usually changes in April, so the tax-year figure can contain weeks at different weekly rates.

This matters when checking a Simple Assessment calculation. Compare the State Pension amount used by HMRC with the entitlement information from the Department for Work and Pensions, and check whether the tax year has been calculated using the correct number of weeks and rates.

Do not use a future weekly State Pension rate to promise that someone will be above or below the Personal Allowance in 2027/28. The final State Pension rate and Personal Allowance for the relevant year must be checked against the official published figures.

What should pensioners do before 2027/28?

There is no need to change a pension or stop a payment because of this announcement. Sensible preparation is administrative:

If you already file Self Assessment for another reason, do not stop filing based on this announcement. The policy concerns Simple Assessment administration for a particular income pattern; it does not cancel a separate legal filing obligation.

Does this change State Pension entitlement?

No. The measure is about tax collection and administration. It does not change:

• the number of National Insurance qualifying years needed for a State Pension;
• the State Pension age;
• the amount shown on a State Pension forecast;
• the taxability of other pension income; or
• the rules for Pension Credit.

For entitlement and forecast questions, use the official State Pension forecast service rather than a tax guide. For Pension Credit eligibility, check the current benefits guidance separately; Pension Credit is not the same as State Pension income and is not brought within this policy merely because both relate to retirement.

Check the sole-income condition carefully

The announced policy is narrower than the phrase “pensioner tax change” suggests. Build an income inventory for the whole tax year: State Pension entitlement, occupational and private pensions, employment, taxable savings interest, dividends, property income, benefits and any other taxable amount. Record whether the State Pension includes increments and whether tax is already collected through another pension or PAYE code. One extra source can change both the tax calculation and the route HMRC uses to collect it.

Use the DWP entitlement information rather than estimating the annual State Pension from a single bank payment. The tax-year amount may include weeks at different rates, and an arrears payment or changed entitlement can require separate checking. Compare the figure on any Simple Assessment letter with the DWP record, pension statements and payments received. If the figures differ, write down whether the difference is timing, entitlement, tax already deducted or an omitted income source before contacting HMRC.

Keep the policy status visible in household records. The Budget announcement describes an intended 2027/28 administrative change and says further detail will follow; it is not a general exemption, a cancellation of State Pension tax or a reason to ignore a letter. When final HMRC guidance is published, update the checklist with the operative scope, notice wording, payment route and correction process. Until then, follow the current notice and official instructions.

Reconcile a Simple Assessment letter

Save the letter, calculation, tax-year reference, payment deadline and HMRC account screenshot or statement. Reconcile State Pension entitlement, other income, tax withheld, Personal Allowance and any amount already paid. If the bill is wrong, use the contact or correction route stated by HMRC and retain the response. If the bill is correct but unaffordable, discuss payment support separately; financial difficulty is not evidence that the calculation is wrong. A planned policy change should not be used to defer a current payment without confirmation from HMRC.
