Latest available figures from 1995-96 are shown in the following table.
National insurance class 3 contributions must normally be made before the end of the sixth tax year following the one for which they were due; but the time limit has been extended for the 1995-96 to 2001-02 tax years. Customers have up to 5 April 2010 to pay if they reach state pension age before 24 October 2004, or 5 April 2009 if they reach state pension age on or after 24 October 2004. Because of this the figures detailed are likely to increase, particularly the latest years.

To date HM Revenue and Customs (HMRC) has sent 2.41 million letters to customers advising them of a potential shortfall in their National Insurance contributions for 2005-06. It expects to issue a further 340,000 in January 2008.
A relatively small number of letters will have been sent in error but it is not possible to determine precisely how many.
The information requested is as follows.

HMRC does not provide specific guidance to employers on whether their employees should pay reduced national insurance contributions. The onus is on employees to give their employers a ‘certificate of election’ form. Without this certificate the employer must deduct full rate national insurance contributions.
Employers are advised to have a procedure in place to ensure employees notify them if they lose the right to reduced rate contributions, (for instance because of divorce or they have cancelled their election). The CWG2 ‘Employer Further Guide to PAYE and NICs’
http://www.hmrc.gov.uk/guidance/cwg2.pdf
and the E13 ‘Day to Day Payroll’ guidance
http://www.hmrc.gov.uk/helpsheets/e13.pdf
provides information on what employers should do where a married women or widow is entitled to pay reduced rate contributions.
