Checking your tax code for 2025-26

Do you know what your 2025–26 tax code means? It affects how much tax is taken from your pay or pension. Check now to make sure you're on the right code and not overpaying! Here's what the letters and numbers really mean.

You can find your tax code:

  • by checking your tax code for the current year online – you’ll need to sign in to or create an online account
  • on the HMRC app
  • on your payslip
  • on a ‘Tax Code Notice’ letter from HMRC if you get one

The tax codes are updated annually. The basic personal allowance for the 2025-26 tax year is £12,570. The corresponding tax code for an employee entitled to the standard tax-free Personal Allowance 1257L. This is the most common tax code and is used for most people with one job and no untaxed income, unpaid tax or taxable benefits (for example a company car).

There are a lot of other numbers and letters that can appear in your tax code. For example, there are letters that show where an employee is claiming the marriage allowance (M) or where their income or pension is taxed using the Scottish rates (S). If your tax code numbers are changed this usually means your personal allowance has been reduced.

There are also emergency tax codes (W1 or M1) which can be used if a new employee doesn’t have a P45. These codes mean that an employee’s tax calculation is based only on what they are paid in the current pay period.

If your tax code has a 'K' at the beginning this means that deductions due for company benefits, state pension or tax owed from previous years are greater than your personal allowance. However, the tax deduction for each pay period can’t be more than half your pre-tax pay or pension.

It is important to check your 2025-26 tax code to ensure the correct information is being used. 
 

Make the most of trivial benefit payments 2025-26

Small gifts can mean big tax savings! Use the trivial benefits exemption in 2025–26 to reward employees with non-cash perks under £50 – no PAYE, no P11D, and no NIC. A smart, simple way to say thanks.

The rules providing trivial benefit payments provide a great opportunity to give small rewards and incentives to employees in the new 2025-26 tax year. The benefit-in-kind (BiK) trivial exemption applies to small non-cash benefits like a bottle of wine, or a bouquet of flowers given occasionally to employees or any other BiK classed as 'trivial' that falls within the exemption.

By taking advantage of the exemption employers can simplify the treatment of BiKs whilst at the same time offering a tax efficient way to give small gifts to employees. The employer also benefits as the trivial benefit payments do not have to be included on PAYE settlement agreements or disclosed on P11D forms. There is also a matching exemption from Class 1A National Insurance contributions.

The tax exemption applies to trivial BiKs where the BiK:

  • is not cash or a cash-voucher; and
  • costs £50 or less; and
  • is not provided as part of a salary sacrifice or other contractual arrangement; and
  • is not provided in recognition of services performed by the employee as part of their employment, or in anticipation of such services.

The rules also allow directors or other office-holders of close companies and their families to benefit from an annual cap of £300. The £50 limit remains for each gift but could allow for up to £300 of non-cash benefits to be withdrawn per director or shareholder per year. The £300 cap doesn’t apply to employees. If the £50 limit is exceeded for any gift, the full value of the benefit will be taxable.

Employment Restrictions After Termination: Be Cautious

Kau Media Group (KMG) Ltd. sought to enforce two post-termination employment restriction (PTRs) contained in a contract of employment to restrict Mr. Hart, a former employee, from working for his proposed new employer, MiSmile Media Ltd. (MML).

Mr. Hart had worked for KMG from November 2020 to late 2024 as an Account Director. From 2021, the defendant became Account Director for MML, a longstanding client of KMG. On the 19th of September 2024, Mr. Hart informed Mr. Khokhar of KMG that he had since taken a job at MML despite being offered more favourable terms, having been approached by the CEO of MML. Mr. Khokhar however made it clear that taking such a job was against the terms of Mr. Hart’s contract.

On the 25th of September 2024, Mr. Hart inaccurately told the claimant he had already signed a contract with MML, before proceedings were started on the 13th of December 2024. The High Court however concluded that KMG did not establish that the PTRs were enforceable with respect to confidentiality and refused the application for injunctive relief on the grounds of ‘restraint of trade’.

The onus was on KMG to demonstrate that the PTRs were reasonable, protected its legitimate business interests, and that any restrictions were commensurate with the benefits secured under the contract. Even though the services provided by MML and KMG were overtly identical, making them potential competitors, the work involved did not comprise a core part of KMG’s dental sector business and thus MML was not effectively in direct competition with KMG. Settled case law has established that legitimate interest does not cover “the skill, experience, know-how, and general knowledge" acquired by an employee, in order to rely on this interest, KMG should have demonstrated ‘objective’ knowledge.

Thus, before incorporating or seeking to enforce any PTRs, ensure that any PTR relied upon is reasonable between the parties, protects the company’s legitimate business interests, and does not venture beyond these demarcations, or else the PTR may be rendered void and unenforceable.

Frozen tax allowances and fiscal drag

Tax thresholds frozen till 2028? That’s fiscal drag in action – more tax paid without rate rises. It’s a stealthy revenue boost for HM Treasury, projected to bring in £38bn a year by 2029. Inflation and pay rises make it worse.

The freezing of tax thresholds often results in a phenomenon known as fiscal drag. When tax thresholds remain static, taxpayers find themselves paying more tax as their earnings increase, without receiving a corresponding rise in tax allowances. Consequently, more individuals are "dragged" into higher tax brackets or start paying tax for the first time, essentially functioning as a hidden or stealth tax. In the UK, several tax thresholds—particularly for Income Tax—have been frozen since April 2022 and are set to remain unchanged until April 2028.

While fiscal drag is not an unusual occurrence, its impact is influenced by three critical factors: the government's setting of thresholds and allowances, inflation, and wage growth. How these thresholds are determined is especially significant during periods of high inflation.

Adjusting tax thresholds to align with inflation or another index is referred to as "indexation." The government’s approach of increasing certain thresholds each year based on inflation is called "uprating." However, this policy is not consistently applied. When thresholds are frozen, tax revenues increase for HM Treasury without the need for any adjustments in tax rates. According to the latest estimate from the Office for Budget Responsibility (OBR), the freeze on Income Tax thresholds is projected to generate an additional £38 billion annually by 2029-30.
