Chancellor Jeremy Hunt has delivered the Autumn Statement for 2023, announcing tax changes which affect the self-employed, business owners, employees and employers. The updates are rolling out at various stages, though some can be expected to start at the beginning of the new tax year in April 2024.

Business rates

The previously announced support package to help those paying business rates will continue, with Hunt saying he will extend the 75% discount on business rates up to £110,000 for retail, hospitality and leisure until 2025.

The Chancellor will also freeze the small business multiplier for a further year, although the large business multiplier will not be frozen.

Full expensing update for businesses

Full Expensing (FE) is a type of first-year capital allowance which permits companies to deduct the full amount of any spending that qualifies from their taxable profits in the year the expenditure occurs.

Originally announced as a temporary measure in the Spring Budget 2023, Full Expensing has now been made permanent.

National Insurance – employees and employers

Although the thresholds for National Insurance will remain frozen until April 2028, the main rate of Class 1 National Insurance payable by employees on their wages between £12,570 and £50,270 will reduce from 12% to 10%.

National Insurance for employers remains unchanged, although employer’s NI relief for veterans is extended by one year, and the £5,000 Employment Allowance will stay in place.

National Insurance – self-employed people

As a self-employed person you’ll make National Insurance contributions based on the profits you make above the National Insurance threshold (so don’t forget to claim tax relief on your expenses!). There are two types of self-employed National Insurance:

  • Class 2 National Insurance is a weekly flat rate. This will be abolished from April 2024
  • Class 4 National Insurance is a percentage of your self-employed profits. From April 2024, Class 4 NI reduces from 9% to 8%

An increase to National Living Wage and National Minimum Wage from April 2024

The National Living Wage is the minimum amount employers must pay to someone who is aged 23 or older, and not in the first year of an apprenticeship. The Chancellor’s statement announced that as of 1st April 2024:

  • National Living Wage will increase from £10.42 to £11.44 per hour
  • The rate will also apply to those aged 21 and older (who currently must receive National Minimum Wage at a rate of £10.18)

Though they sound similar, the National Living Wage and minimum wage are different. The National Minimum Wage (NMW) sets the minimum hourly rate which employers must pay younger employees and apprentices. These rates will also increase from 1st April 2024.

R&D tax relief changes

Hunt announced a planned simplification of the current Research and Development (R&D) system, merging the existing R&D Expenditure Credit (RDEC) and SME schemes from April 2024 onwards.

The Chancellor also confirmed a reduction in the ‘intensity rating’. This refers to the proportion of expenditure that loss-making businesses must spend on R&D activities in order to qualify for additional relief in the form of a 10% cash credit.

Under current rules, R&D must account for 40% of a loss-making company’s spending to qualify, but this will reduce to 30% for accounting periods that start on or after 1 April 2024.

There will also be a grace period for companies which dip below the 30% threshold, allowing them to continue receiving relief for one year.
