i am sure you can only put 15% of the money you earn in to a pension, a manager at a place i use to work at use to pay that as that was the most he could, he also use to buy stamp every month as an investiment
Depends on the agew of the pension holder. The older you get, the higher the percentage you can put in and get the tax relief.
Also, what someone else was asking re tax bill. The pension is treated as pretty much as an item that carries 100% tax relief in the year you bought it
e.g. if your profit is say, £25,000, the tax bill on that will be about £3,800 (ignoring the extra NI element here for the sake of simplicity). The £3,800 is calculated as follows:- £25k - £6k tax free allowance = £19k. 20% of £19k = £3,800.
Now if you paid £3k into a pension pot that year, it doesn't mean that your tax bill will only be £800. It
does mean that the £3k pension money will be subtracted from the £25k profit giving the following calculation:-
£22k profit - £6k tax free allowance = £16k. 20% tax on £16k = £3,200.
So the actual tax bill will be £3,200 rather than £3,800.
These are only approximations and NI has been left out for the sake of simplicity.
