HMRC confirms tax code changes for the new tax year
HMRC has announced tax code changes for the 2026–27 tax year, affecting millions of employees, pensioners and self-employed individuals across the UK. Tax codes play a crucial role in determining how much Income Tax is deducted from your earnings, so even small changes can impact your take-home pay. Understanding what these updates mean — and checking your code early — can help you avoid unexpected tax bills or overpayments.
Why tax codes are updated each year
HMRC regularly reviews tax codes to reflect changes in personal circumstances and government policy. Adjustments may be made for benefits in kind, changes in employment, multiple income sources, or updated allowances. For 2026–27, HMRC has confirmed that updated codes will be issued to ensure PAYE deductions remain accurate. If you rely on your employer or pension provider to deduct tax, keeping an eye on tax code changes is essential to staying compliant.
Key tax code changes HMRC is introducing
Among the updates for 2026–27, HMRC is refining how allowances and adjustments are reflected in PAYE codes. This includes clearer treatment of untaxed income, changes to how estimated expenses are handled, and improved accuracy where individuals have more than one income stream. HMRC has also reiterated that digital information sharing will play a bigger role, helping tax codes reflect real-time data. You can read more about how tax codes work on the official HMRC tax codes explained guidance page, which outlines how PAYE codes are calculated and applied.
Who is most affected by tax code changes
While most people will see little or no change, some groups are more likely to be affected by tax code changes for 2026–27. These include individuals with company benefits, those receiving state or private pensions, and anyone with multiple jobs. Freelancers moving between PAYE and self-assessment may also notice differences. Reviewing your tax code notice (P2) when it arrives can help you spot errors early and request corrections if needed.

Misunderstood codes can lead to underpaid tax, penalties, or cash-flow issues. Industry bodies also stress the importance of professional oversight when dealing with PAYE and tax code updates. Further insights are available through UK tax professional guidance, reinforcing that combining expert advice with regular checks is the safest way to manage HMRC updates.
