Income Tax & National Insurance Thresholds Freeze Extended

Income tax and national insurance thresholds will now stay the same until March 2031 which is three years later than the original freeze.

The personal allowance, i.e. the amount that can be earned without being subject to income tax is £12,570 per annum. This has remained the same since 2021.

Current Income Tax Bands

Basic rate                    £12,571 to £50,270                      20%

Higher rate                  £50,271 to £125,140                    40%

Salary Sacrifice National Insurance Cap

National insurance relief will be capped at £2000 of annual salary sacrificed pension contributions from April 2029.

Currently if an employee contributes pensions via a salary sacrifice scheme they reduce their income by the amount of their pension contributions and neither they nor their employer pay tax or national insurance on the reduction.

From April 2029, employees will be able to reduce their income for the purposes of income tax by any amount they choose to contribute. However, they will only be able to reduce their income that is subject to national insurance by £2000 each year.

This means that both employees and employers will lose out on national insurance savings and may deter pension savings in the future.
