Thank you for making your very helpful and important point about NI contributions and salary sacrifice. I fully agree that if an individual can have access to the salary sacrifice mechanism for extra pension contribution, they will end up gaining more on the order of 32% at the moment of contributing, and perhaps even more, if the employer is willing to make an additional pension contribution to reflect that the employer NI contributions have also been reduced.
Also, I should indeed have written that "up to 75%" of the money taken from the pension pot gets taxed as income, except for people with pension pots larger than £1.073 million who might end up paying on more than that given the cap on tax-free cash. I do believe that many people who are well below that cap will still end up paying tax on nearly 75% of money coming out of the pension pot, and will avoid tax only on the 25% tax-free portion and perhaps a bit more, because other income sources will use up most if not all of that £12,500 personal allowance. For example, if they have a full state pension, I believe that will be £11,500 from April 2024, leaving just £1000 of the personal allowance available.
I assume you meant that the overall tax free amount can be greater that 25%, not that it is greater than 75%, ie I assume that 75% was a typo. So the effective tax rate on that pension income can end up being 15% or a bit less, for a taxpayer who is at basic rate both while working and also in retirement. Yes, that is better than the usual 20%, even for taxpayer who cannot use salary sacrifice. But against that, if the money had gone into an ISA, instead, the original contribution would have been taxed, but after that all of the gains and income would be totally tax-free. Also, that money will be accessible if needed.
So while I am definitely not saying that extra pension contributions are never worthwhile for a basic rate taxpayer, I am saying that looking at specific circumstances is useful because there are many scenarios in which those extra pension contributions are not the best option for a basic rate taxpayer, and alternatives such as ISAs are worth considering.
On the other hand, for an additional rate taxpayer or higher rate taxpayer who is also perhaps closer to retirement age, on the balance of probabilities, if they are not exceeding the annual allowance (and assuming the penalty charge on accumulations exceeding a certain level does not get reinstated), the net tax relief from making the extra pension contributions is much more likely to be high enough to justify the restrictions and embedded tax liabilities that pensions carry.
My bottom line opinion at the moment would be that for a higher rate taxpayer who is not hitting up against allowances, or for a basic rate taxpayer who can use salary sacrifice, extra pension contributions will often be a good idea if they can afford the lack of access to those funds for a long time. Conversely, for a person who values the flexibility more and/or may be a basic rate taxpayer with no salary sacrifice available,
Thank you again for having pointed out the inaccuracies you noticed, and especially the very important point about salary sacrifice and NI contributions. I really do appreciate it.
