National insurance borne by a shareholder-director in 2019/20 remains at 25.8%. That is the director as an employee will pay 12% while the company as employer will pay a further 13.8%.
If you have income from more than one job, or if you have self employment income as well as being employed, you should take care to ensure that you do not pay more in national insurance contributions than you need to.
The prescribed annual maximum normal contribution for an individual is 53 weeks at the standard primary (employee) Class 1 contribution rate between the earnings threshold and the upper earnings limit. For 2019/20 this works out to be £5,062.56. There is also an additional 2% payable on earnings in excess of the upper earnings limit.
Class 1 contributions
The Contributor Deferment Group will tell you for which employments they have allowed deferment of contributions and will send to the relevant employer(s) a certificate telling them not to deduct primary class 1 contributions from you during the tax year and asking them to refund any contributions they may already have deducted from your wages/salary during the year.
Class 2 contributions
If you expect your earnings from self-employment to be less than the small earnings exception limit (£6,365 for 2019/20), you may apply for exception , you may apply for exception from paying class 2 contributions.
However you may, if you wish, continue to pay class 2 contributions voluntarily to keep up your entitlement to the benefits they provide (Incapacity Benefit, Retirement Pension, Widow’s Benefit and Maternity Allowance).
You will need 35 full years of NICs to be entitled to a full state pension, which you can check on your online personal tax account.
Class 2 contributions may be deferred if you can show that you are otherwise likely to pay above the annual maximum normal contribution (£5,062.56 as set out above) in class 1 and class 2 contributions.
After the year-end
After the end of the tax year, the deferment group will work out your overall contribution position for the year and collect any balance of contributions that may remain payable.
