Best buy cash ISAs 2013/14:
EVERYONE over 16 in the UK gets
an allowance of £5,760 to save tax-free, each tax year, in a cash ISA. You don’t need to lock the cash away in one, many are easy-access and, once in, the cash stays tax-free year after year.
Don't worry if you've opened one in past years, you can open another — with a different provider if you choose. This daily-updated guide compares best buys and includes special calculators.
What is an ISA?
For years now, whether on telly, radio or in his book, Martin's used the same analogy to explain ISAs. So why stop now? Here come the cakes!

For a more detailed explanation of ISAs, (don't worry, it still includes cakes) see the ISA Guide.
How do cash ISAs work?
A cash Individual Saving Account (ISA) is just like a normal savings account - you can take cash out whenever you want, the only difference is the interest isn't taxed. For the current 2013-14 tax year, the annual ISA allowance is £11,520, but only £5,760 of that may be used for a cash ISA.
Everyone aged 16 or over can save their allowance in one each tax year (6 April-5 April). And the real kicker is...
Keep the money in the ISA - it stays tax-free, YEAR AFTER YEAR.
With normal savings, basic rate taxpayers hand over 20% of the interest to the taxman, higher rate taxpayers 40%, - but in an ISA, you keep that. So basic rate taxpayers earn a quarter more interest at the same rate in a cash ISA, and higher rate taxpayers two-thirds more.
However, there are many confusions with cash ISAs, so to spell it out....
1. Money may be withdrawn at any time without losing tax benefits
Providing you've picked an easy access ISA, you can withdraw the money whenever you want, just like a normal savings account. The key thing to remember is once the money's withdrawn, it can't be returned.
An example should help. Say you save £4,000. That leaves £1,760 left to put in. Then two months later, still in the same tax year, you take out £2,000. You can still ONLY put £1,760 back in.
2. You get a new ISA allowance each tax year

Each tax year (6 April until the next 5 April) everyone aged 16 or over gets a new cash ISA allowance. But if you don't use it, you lose it.
Once that year's closed, you can't put another penny in that specific cash ISA allowance. So if you put aside nothing in the 2012-13 year, that's it - it's gone. If you put £2,000 in, even though that year's maximum was £5,640 - the year is closed, you can't now top it up.
Yet if you do deposit the cash in time, you can keep it in there, tax-free for as long as you like.
As soon as the new tax year starts on 6 April, you can put a whole new year's allowance in.
3. You can have lots of ISAs, but only from different years
The golden rule is you can only open a cash ISA with one provider in a tax year, you can't split it. However you can hold lots of different cash ISAs from different years with different providers.
So if you opened a cash ISA with Barclays two years ago, you don't need to stick with it for this year's cash ISA, you can choose whoever the top payer is.
4. You can transfer ISAs from past years to up the rate from pitiful lows
ISA providers love us to think once our money's in, its a done deal. This is wrong. You have a right to transfer past years' cash ISAs to the new best buys - and if you've got serious cash saved in them, this can make a massive difference.
For full pros and cons on this, and which top paying cash ISAs allow you to transfer, see the full Cash ISA Transfers guide.
5. Make sure your savings are safe
Provided your money is in a UK-regulated bank or building society account, it's protected under the Financial Services Compensation Scheme (FSCS). Its golden rule counts for cash ISAs too...
The first £85,000 per person, per financial institution is guaranteed.
While that sounds simple, the exact rules are more complex - not every bank in the UK is UK-regulated and there are complex rules involving how different banks are registered and what counts as a financial institution. For full info on the rules, see the detailed Are Your Savings Safe? guide.
How to maximise safety
If you've more than £85,000 of savings (including cash ISAs and others) in one bank then, in the unlikely event it went bust, only the first £85,000 is fully guaranteed. So for total peace of mind, don't put more than this in any one institution. Spread it around instead.
This guide and best buys
It's impossible to pick "which bank is in trouble?" We've seen great names of world banking like Goldman Sachs and Merrill Lynch in trouble.
Therefore our preferred option is to report the top rates regardless, but to let you know if it's not covered by the UK protection.

The UK's top rate cash ISAs
This guide is updated daily with new products that top the best buy tables. The top ISAs currently available for 2013/14 are below.
Watch out for short term bonuses, withdrawal limits & more
When picking the one for you, in general, higher interest is better, yet tricks like short-term bonus interest rate hikes, limited withdrawals and transfer penalties abound. We explain them below. Most cash ISAs are 'variable rate', meaning providers can change them whenever they decide to, so regularly check the rate's still competitive. If it's not, transfer it.
Always check how long it will take to get your money
We list the top rate ISAs, but some of these accounts have withdrawal restrictions or penalties. If you might need it, make sure the ISA you pick allows you to easily access your money.
Consider locking in if you don't need the cash
Or, if you know you won't need to get access to your money this tax year, consider locking it away - see the top Fixed Rate Cash ISAs. However, at the moment, very few fixed rate accounts offers more than the top instant access ISA - but they do offer certainty over the rate.
Finally, check local credit unions or branches of smaller building societies, which often have good rates for locals.

Regular Saver ISA
Regular saver ISAs work the same way as normal regular savings accounts, which require you to pay in something (up to a set maximum) each month, except in the ISAs the interest isn't taxed.
Newcastle BS, 3% AER (2% if you withdraw cash) Must deposit £1-£500/mth. No good for lump sums
- Rate: 3% AER (if no withdrawals made)
- Monthly deposit: £1 - £500
- Interest paid: Monthly
- Allows previous ISA transfers? No
- Transfer out penalties? No
- Access: Online, phone, post or branch
- Safety: Full £85,000 UK protection
A substantially higher rate's on offer with Newcastle's Big Home Saver ISA. it pays 3% AER each month that you pay in £1-£500 and don't make a withdrawal. Yet take cash out, or miss a pay-in, and you only earn 2% AER for that month.
So, while no good for saving a lump sum upfront, if you'll pay in most months and not make too many withdrawals, this still beats Cheshire above. Even if your interest drops to 2% in three or four months per year, the overall return with Newcastle is likely to be greater. You can't transfer previous years' ISA allowances into this account.

Newcastle Building Society has the full £85,000 UK savings safety guarantee. See more information about the Savings Safety rules.
It's called the Big Home Saver because if you use the saved funds to get a mortgage with Newcastle, you get either £500 or £1,000 cashback when you complete on the mortgage. If you don't get a mortgage with Newcastle, then you don't get the cheque. Interest payments are unaffected.
Although you can pay up to £500 into the account each month, watch that over the 12 months you don't put more than £5,760 into your cash ISA. If you put £500 in each month for 11 months, your final payment will need to be £260 - fail to change this and Newcastle BS will reject the payment.
To see how switching will affect your savings, use the ISA Savings Calculator and input the interest.

The top fixed rate accounts
If you're willing to lock your cash away, there are some alternatives which guarantee rates for a set period of time. Yet remember...
Fixed rate ISAs give a guaranteed rate for a set period, but you will face severe penalties if you try to take money out during that time.
Therefore they're mainly suitable for those happy to lock cash away for the entire term - meaning you lose the flexibility to ditch and switch to a better payer if the rate is no longer competitive.
Also, at the moment only longer fixed rate accounts beat the top easy access rates available, so consider very carefully before locking your cash away. Top easy access rates could drop, but equally they could rise, and then you'd be trapped.
The best one-year fixed rates
Rates are very poor on one-year accounts - you can get 2.5% AER in the top easy access accounts above, compared with 2.35% in the highest one year fixed.

Inflation-beating ISA savings
An alternative to fixing is to get an account that gives you a rate guarantee for a certain period. However, you usually have to lock cash away for up to five years, so only go for it if you are totally sure you won't need access. Unfortunately, savings rates are poor at the moment so there aren't any available - see full details in the Inflation-Linked Savings guide.
Cash ISAs: Q&A with Martin Lewis
Filmed on 14 March 2011
What about Toisas?
The Tessa-only ISA, tongue-twistingly known as a Toisa, was another special tax-free product. Old style Tessas, the forerunner of the cash ISA, lasted for five years and then matured. If this occurred any time between 1999 and 2004, the Tessa automatically turned into a Toisa.
Since April 2008, all Toisas have become simple Cash ISAs, meaning all normal ISA rules apply. You can no longer add funds to an old Toisa, but if you have any money left in one, you can transfer it and up the rate. See Cash ISA Transfers for the best accounts that let you move money in.
The Savings Calculator
When using the calculator below, for increased accuracy use the AER (Annual Equivalent Rate) which should be listed on your statement. Obviously as most accounts' interest rates are variable, the answers will change if the rate does, so only use the calculator as a rough indicator of the likely outcome.
The calculator assumes you put money in at the beginning of each month, so if this isn't how you do it, the answers will be ever-so-slightly out. If you don't make regular deposits but put in lump sums, figure out the monthly equivalent for a rough answer. Feel free to play with the results to see how your savings are affected.
The size of the saving
A basic rate taxpayer saving £5,760 over three years, in a poor savings account, of which there are sadly many, would earn £14 interest. In a top savings account it's £281, but the same amount in the top cash ISA, as it's tax free, earns £461. Yet not all cash ISAs are the same. One of Halifax's pays a paltry 0.1%, meaning it'd underpay the market leader by nearly £450.
The benefits are even bigger for top rate taxpayers; then the top cash ISA outperforms the top savings account by more than £270.
