Tax-free calculator

If you're a taxpayer, you may want to make the most of every opportunity to invest your money tax-free. This means you get to keep all the interest or returns earned from the investment, without a penny going to the taxman.

This quick and easy tax-free investment calculator will help you find out how much you could invest tax-free with us today.

Your existing NS&I tax-free investments

Please enter the amount you have already invested in the following NS&I tax-free products. For our Direct ISA, only enter the amount you have paid in to the account during this tax year (6 April 2010 to 5 April 2011). For Savings Certificates, you only need to enter the amount you hold in the current issues (do not include Certificates from earlier issues).

Every time we change the fixed rates on offer, we bring out a new Issue — which means you can invest up to a further £15,000 tax-free in each Issue.

• This covers NS&I products only. It excludes products such as stocks and shares ISAs and offshore investments.
• The tax-free calculator is intended for use by taxpayers, who could benefit by not paying tax on their investment returns. For non-taxpayers.our investments that pay gross returns may offer a better deal — see Help me to decide to find out more.
• The accuracy of the amount we say you can invest tax-free with NS&I depends on the accuracy of the information you enter. Information you enter is completely anonymous and will not be stored.
