New ISA limits

New ISA limits

17 April 2012 / by Oliver Roylance-Smith

The start of the new tax year brings a new and increased ISA allowance which is available to use now, even if you invested last year’s allowance right at the last minute. We take a quick look at how much you can invest and what tax savings can be made by acting now.

The new tax year

The new tax year runs from 6th April 2012 to 5th April 2013 (known as the 2012/13 tax year) and you must use your allowance within that timeframe or you will lose it – ISA allowances cannot be backdated or carried over.

Two types of ISA allowance

There are two types of ISA allowance – a cash ISA allowance and an investment ISA allowance (sometimes referred to as a stocks and shares ISA). Every individual in the UK over the age of 16 for cash ISAs and age 18 for investment ISAs has an ISA allowance.

The limits for the two types are as follows:

Cash ISA allowance

The cash ISA limit for the 2012/13 tax year is £5,640. Any amount up to this limit can be made into a cash ISA with one provider.

Based on a fixed return of 5%, the tax saving between maximising your cash ISA allowance at the start of the tax year rather than waiting until the end of the tax year is around £56 for a basic rate tax payer and £112 for a higher rate tax payer.

Investment ISA allowance

The investment ISA limit for the 2012/13 tax year is £11,280. You can invest this maximum provided you have not made any use of your cash ISA allowance. If you have made a contribution to a cash ISA during the current tax year then you are able to invest the remainder of the £11,280 allowance into an investment ISA. For example, if you put the maximum into a cash ISA during the tax year, you are still able to put up to an additional £5,640 into an investment ISA.

Based on a yield of 7%, the tax saving between maximising your investment ISA allowance at the start of the tax year rather than waiting until the end of the tax year is around £157 for a basic rate tax payer and £315 for a higher rate tax payer.

The allowance is per person

Remember, each ISA allowance is per person, so if you are married or have a partner, the totals permitted are doubled since each of you is able to contribute up to the maximum.


You can also transfer ISAs from previous tax years. All previous cash ISAs can be transferred into a new cash ISA (subject to the terms and conditions of the new plan) and most investment ISAs will accept transfers from both previous cash ISA as well as investment ISAs.

You should note that once you have transferred a cash ISA into an investment ISA, you cannot then transfer it back to a cash ISA.

The cumulative effect

Also remember the beneficial tax treatment is maximised over time when the full effect of compound growth is achieved. Ignoring any growth, if you had put the maximum into a cash ISA for each year since 1999, this equates to over £50,000 whilst the maximum into an investment ISA each would equate to almost £110,000, all of which would also benefit from tax free income and growth. This is per person, remember!

These amounts go some way to highlight the importance and benefit of putting the maximum into this valuable tax break each year.
