The main rate of Class 4 National Insurance contributions for the self-employed to increase from 9% to 10% in April 2018 and 11% in April 2019
The increases, applying to earnings between £8,060 and £43,000, will raise £145m a year by 2021-22 at an average cost of 60p a week to those affected. All Class 4 earnings above £43,000 will continue to be taxed at 2% while those below £8,060 will pay nothing.
Class 2 National Insurance, a separate flat rate contribution paid by self-employed workers making a profit of more than £5,965 a year, is to be scrapped as planned in April 2018
Taken together, millions of self-employed workers could pay an average of £240 a year more but ministers say those earning £16,250 or less will pay less
No changes to National Insurance paid by the employed and employers or to income tax or VAT
Personal tax-free allowance to rise as planned to £11,500 this year and to £12,500 by 2020Share
