National Insurance Refund Due?
There is a limit as to how much National Insurance Contributions (NIC) you can pay. Particularly if you have income from private practice as well as your NHS salary, you may be due a refund.
Many Consultants and GP Locums pay more NICs than they need to because collection of the different classes of contribution are handled separately during the year- and the National Insurance Contributions Office (NICO) is not obliged to check for overpayments at the end of the tax year so repayments are not automatic.
If you fall into either of the above categories there is a good chance that you have overpaid – unless you applied for deferment in advance.
