Whether you're employed or self-employed, there's a limit to the amount of National Insurance contributions you need to pay each tax year. If you overpay or wrongly pay National Insurance contributions you can claim the money back.
You pay National Insurance contributions if you are an employee or are self-employed, and you are aged 16 to State Pension age (currently 65 for men and 60 for women), providing your earnings are over a certain level. Entitlement to some benefits, such as the State Pension and Jobseeker's Allowance, depends on the type and amount of National Insurance contributions you have paid or been credited with.
The following amounts apply for the 2009-10 tax year.
If you're employed
If you earn above £110 a week (the 'primary threshold') you pay 11 per cent on the excess over £110 as 'Class 1' National Insurance contributions up to the upper limit of £844 earnings per week. You also pay 1 per cent of earnings above £844 a week as Class 1 National Insurance contributions. Below £110 you pay no National Insurance contributions.
If you're self-employed
You pay 'Class 2' National Insurance contributions at a weekly rate of £2.40. However, if your earnings in the 2009-10 tax year are expected to be less than £5,075 then you may be entitled to the Small Earnings Exception and not pay Class 2 National Insurance contributions. You can apply for Small Earnings Exception for the 2009-10 tax year on form CF10 Application for exception from liability for Class 2 contributions. Class 2 National Insurance contributions must be paid unless you apply for, and are issued with, a certificate of exception.
In addition to Class 2 National Insurance contributions, you also pay 'Class 4' National Insurance contributions on a percentage of your profits. You pay 8 per cent on annual profits between £5,715 and £43,875 and 1 per cent on any profit over £43,875.
Class 4 National Insurance contributions are an annual charge and are paid along with tax through the Self Assessment system in two 'payments on account' and (if appropriate) a final 'balancing charge'.
Because they are an annual charge you will still have to pay Class 4 National Insurance contributions on any profits for the year in which you reach State Pension age. For example, if you reach State Pension age on 1 May 2009 you will still have to pay Class 4 National Insurance contributions on all of your annual profits above £5,715 for the 2009-10 year, but will be exempt from Class 4 National Insurance contributions for tax years from 6 April 2010.
You might have overpaid or wrongly paid National Insurance contributions if:
HMRC's National Insurance Contributions Office usually gets in touch if you've paid £47.50 or more above the annual limit for Class 1 and/or Class 2 National Insurance contributions. However, if you think you've overpaid but haven't been notified write to them after the end of the tax year (5 April).

You can complete form CA8480 to apply for a refund of Class 2 National Insurance contributions which have been paid incorrectly or in excess.
There is no deadline for reclaiming excess contributions where, for example, you had two jobs or were both employed and self-employed. If you have wrongly paid for any other reasons, there is normally a six-year time limit for claiming a refund.
If you are claiming a Class 2 National Insurance contributions refund because your self-employed earnings for the tax year were below the Small Earnings Exception limit, you must apply for it in writing between 6 April and 31 January following the end of the relevant tax year, and provide evidence of your earnings for the whole tax year.
If you're an employee and you pay Class 1 contributions with two or more different employers or you are an employee paying Class 1 contributions and also self-employed and paying Class 2 and/or Class 4 contributions, you may be able to 'defer' some of your contributions to prevent an overpayment.
You may be able to claim a refund if you think you wrongly paid voluntary National Insurance contributions where all of the following apply:
Note that strict criteria must be met in order to qualify for a refund in these circumstances.
