ISA or Pension

A pension is vital. The state pension is hardly generous, even for a couple, and doesn’t kick in until the late 60s. A pension means you can live better and you can retire earlier than state pension age. As we will see later, that pension can be held in a pension account or in an ISA.

Why use a pension rather than an ISA?

• Your employer might be contributing heavily to your pension. This free money is incredibly important, and rarely to be declined. Currently I contribute 6% and my employer contributes 10%. I consider that 10% to be like a guaranteed bonus and a part of my pay package.

• Then there’s a tax reason. Many people move to a lower marginal tax rate when they draw a pension, rather than having a full-time job. This is enhanced because pension income has no NI charges.
So for example, you might earn now with a 42% marginal rate (tax plus NI), but in retirement your marginal rate is 20%. For people like me who should stay a little under the Lifetime Allowance, it seems possible to stay at the 20% rate in retirement if we plan carefully, assuming conservative growth. (With high growth the nice problem of paying 40% tax on SOME of the pension appears, and/or leaving some money in drawdown when I die.)
In your early 50’s this tax reason can be really important. If we have a few thousand spare, it’s going into my or my wife’s SIPP rather than pay off the mortgage – I’ll pay that off when the tax-free pension cash lands in my current account at age 55.  (There’s reasons for using my SIPP and other reasons for using my wife’s SIPP instead.  For a rarely mentioned reason, see Pension page “6 – Model” section “Improvement 1”.)

• Related to that, if you pay 20% tax then you probably pay 32% including NI. In retirement you might pay 0% or 20% on pension income but no NI.

• Student loan 9% and child benefit taper mean that at times your marginal rate could be far higher than 42% (40%+2%). You might want to make extra AVC or SIPP contributions at that time.

• Some pension (often 25% of it) is available tax free from age 55. (See the page on drawdown)

• Without employer contributions or these tax differences, the mathematical advantage of a pension disappears. The non-mathematical reason to have a pension is that some people find it good to have the pension locked away so there’s no temptation to spend it.

On the other hand…

• A few years ago, my wife and I had built up a reasonable ISA intending to clear the interest-only mortgage. But then we decided that by renegotiating timings with our building society we could use some of it on a few years of kids’ education costs. If we’d had it in a pension, we wouldn’t have had the choice. OK, our ISA wasn’t set up as an alternative to a pension, but the point is that an ISA offers choice.

If you exceed your lifetime allowance you might wish you’d put your excess money in your spouse’s pension or in an ISA instead. (There’s a separate page on the impact of the LTA).
