Individual Savings Accounts (ISAs) were introduced in 1999 to replace old-style tax free savings. They allow you to invest up to a set allowance each tax year (6 April to 5 April) on which you will pay no tax on any interest you earn. The current allowance is shown below.

  1. You must be at least 18 years of age to invest in an ISA.
  2. An ISA may only be held by an investor in his or her sole name. Joint accounts are not allowed.
  3. The start date for your ISA is the date of the first deposit.
  4. You can save in one Cash ISA per tax year (6 April to 5 April) with Newbury Building Society up to the total annual ISA allowance. The remainder of the annual ISA allowance can be invested in a single or multiple Cash ISAs or a Stocks & Shares ISAs with another provider subject to the providers ISA Terms & Conditions.
  5. You must be resident in the United Kingdom for tax purposes or, if not so resident, either perform duties which, by virtue of Section 28 of Income Tax (Earnings & Pensions) Act 2003 (Crown employees serving overseas), are treated as being performed in the United Kingdom, or you must be married to, or in a civil partnership with, a person who performs such duties. You must inform Newbury Building Society if you cease to be so resident or to perform such duties or be married to, or in a civil partnership with, a person who performs such duties.
  6. Your yearly allowance does not roll over, so if you do not use it, it will not be added to the next year’s allowance.
  7. For a period of 30 days after opening your ISA, you may instruct us that you have changed your mind and we will return your deposit to you, subject to cheque clearance, with any accrued interest (tax will not be deducted). Alternatively, we can help you switch to another savings account with us (conditions allowing). The 30 day cancellation period starts on the day you open your Cash ISA and ends at close of business on the 30th calendar day. To cancel your ISA agreement with us, you can either visit or write to your local branch, enclosing your passbook.
  8. On the instructions of the investor an ISA with all rights and obligations shall be transferred to another ISA manager within five working days.
  9. An ISA may not be transferred from one investor to another. However, in the event of death, the ISA subscription allowance (known as an ‘Additional Permitted Allowance’ APS) can be passed to a surviving spouse or civil partner.
  10. The ISA must cease on the date of death of the investor. Interest will be paid gross up to the date of closure. Up to a maximum of 3 years after the date of death. Interest arising after the date of death will be subject to deduction of income tax at the appropriate rate and should be declared to HMRC as part of the deceased tax liabilities.
