Chancellor Rachel Reeves has confirmed the Budget 2025 tax and NIC threshold freeze, extending key Income Tax and NIC (National Insurance Contributions) thresholds through the 2030–31 tax year. The Inheritance Tax nil-rate band (NRB) and residence nil-rate band (RNRB) are also confirmed as frozen to April 2031, extending prior legislation that had run to 2027–28.
These measures are drawn from announcements in Budget 2025 and remain subject to enactment in Finance Bill 2025 and subsequent HMRC guidance. For an overview of how IHT allowances operate, HMRC’s Inheritance Tax guidance provides a useful reference.
Implications of the Budget 2025 tax and NIC threshold freeze on income, NICs, and IHT
The extended freezes are designed to raise revenue via fiscal drag rather than headline rate increases. As nominal earnings and asset values rise against fixed thresholds, more taxpayers are drawn into higher bands.
Headline measures
Income Tax (England, Wales, Northern Ireland – earned income)
- Personal Allowance held at £12,570 through 2030–31.
- Basic rate limit held at £37,700, keeping the higher-rate threshold at £50,270.
- Additional rate threshold held at £125,140.
- Personal Allowance taper unchanged: £1 withdrawn for every £2 of adjusted net income above £100,000, fully removed by £125,140.
Note: Scotland sets its own earned income bands.
National Insurance Contributions
- Employees (Class 1): Key thresholds, including the Primary Threshold alignment and Upper Earnings Limit, are held in cash terms over the extended period. The NICs secondary threshold is explicitly maintained to 2031.
- Self-employed (Class 4): Lower Profits Limit and Upper Profits Limit remain fixed in line with the income tax bands over the extended freeze.
Inheritance Tax
- NRB remains at £325,000 and RNRB at £175,000, both frozen to April 2031.
- RNRB taper above £2 million of estate value continues to apply.
- Transferability of unused NRB and RNRB between spouses or civil partners remains available, potentially allowing up to £1 million combined where conditions are met.
- For practical planning, review our Wills & Probate service to ensure estates are structured to optimise available allowances.
Fiscal Drag Explained
Fixing thresholds while wages and prices rise:
- Increases the number of taxpayers.
- Pushes more income into higher bands (“bracket creep”).
- Makes fixed “cliffs” bite more frequently, such as the High Income Child Benefit Charge, the Personal Allowance taper, and the RNRB taper.
Media and OBR-linked reporting highlight substantial added revenues and more higher-rate taxpayers by 2029–30 and into 2030–31 due to the extended freezes.
Implications at a Glance
Income Tax
- Nominal pay growth lifts liabilities even if real incomes are flat.
- More earners move into 40% and 45% bands as £50,270 and £125,140 remain fixed.
- The 60% effective marginal rate from the Personal Allowance taper applies between £100,000 and £125,140 more frequently.
NICs
- A larger portion of pay attracts NICs as thresholds are met sooner with pay rises.
- Employer costs rise against a frozen secondary threshold.
- Salary sacrifice arrangements (e.g., pension contributions, approved benefits) become relatively more valuable.
Inheritance Tax
- More estates exceed NRB/RNRB as property and asset values rise.
- The £2 million RNRB taper threshold increasingly restricts access to the RNRB.
Things to Consider
Individuals and Families
- Model adjusted net income around £50,000 (HICBC), £100,000 (PA taper), and £125,140 (additional rate/allowance fully lost).
- Use gross pension contributions and Gift Aid to manage adjusted net income within the taper and band thresholds.
- Maximise ISAs; review dividend, savings, and CGT exposure.
- Check Marriage Allowance eligibility where appropriate.
Employers
- Budget for higher effective employer NICs as pay rises meet frozen thresholds.
- Review and communicate salary sacrifice and benefits to support tax-efficient saving.
Estate Planning
- Review wills, RNRB eligibility (qualifying residence to direct descendants), and transferable allowances.
- Consider lifetime gifting within exemptions and whether life cover in trust is appropriate for expected liabilities.
- Monitor estate values relative to the £2 million RNRB taper threshold; note downsizing provisions for RNRB.

Compliance and Operations
- Update payroll/tax systems and planning models for freezes through 2030–31.
- Expect more taxpayers to enter Self Assessment as fiscal drag lifts incomes into higher bands.
- Track Finance Bill 2025 and subsequent HMRC publications for technical detail and any transitional rules.
- Households and businesses should consider the implications of the Budget 2025 tax and NIC threshold freeze when planning remuneration, savings, and estates through 2030–31.
Note: The updates above reflect Budget 2025 confirmations of freezes to April 2031 for Income Tax thresholds, the NICs secondary threshold, and IHT NRB/RNRB; Scotland’s earned income bands remain separate.
