2023 investment tax allowances: ISAs just got real

Your stocks and shares ISA is now even more important.
2023 investment tax allowances: ISAs just got real

For a while there it felt like it made sense to install a few revolving doors on Downing Street. The current bunch in charge seems to be sticking around but investors might have noticed their prudent approach to balancing the books comes at a price. 

In November, the chancellor laid out clear plans to raise tax on investment gains and 2023 is when it all kicks off.

The amount we can earn in dividend income and outright investment growth (capital gains) is falling from April 2023. With both allowances being chopped in half, and then again in 2024, it means a lot of investors will pay tax on their investments for the first time.

If you haven’t thought about investing tax efficiently, then, it might be wise to at least work out if a tax-efficient account like a stocks and shares ISA or self-invested personal pension (SIPP) could help now more than ever.

Eligibility to invest into an ISA or SIPP and the value of tax savings both depend on personal circumstances and all tax rules may change.

2023/24 dividend and capital gains allowances

If you aren’t investing using a stocks and shares ISA or a longer-term tax-efficient account like a SIPP you could be forking out a load of extra tax come April.

Often, investors will opt for the cheapest investment account out there and on the surface that makes sense. Why pay more than you have to? But investing solely in a general investment account (GIA) because it has a lower headline cost than an ISA risks missing the whole point, tax.

Now, it may be that you’ve decided you’re unlikely to go above your personal investment tax allowances. In which case, it’s probably true that an ISA wouldn’t be as useful. But, given those allowances are coming down fast (see the chart above) it’s maybe worth revisiting those assumptions.  

New UK dividend tax allowance from April 2023

Putting the changes to the dividend allowance into perspective, a basic rate taxpayer earning £2,000 in dividends in the 2022/23 tax year, and earning the same dividend income for the next two years, would suddenly have to pay £87.50 in 2023/24, then £131.25 in 2024/2025.

The rise in dividend tax is even more pronounced for higher rate taxpayers, who would pay £506.25 in 2024/25, and additional rate taxpayers, who’d owe £590.25.

That’s a big chunk of change for anyone, and let’s not forget it could be even bigger if your dividend payments grow, like we all hope they do.

New UK capital gains tax rates from April 2023

Dividend allowances aren’t the only limits getting the chop in the 2023/24 tax year. The amount we can earn from the growth of our assets and not pay UK tax each year (your capital gains tax allowance) is also falling from £12,300. First, to £6,000, then to £3,000 the year after.

Of course, if you don’t sell any assets it doesn’t matter all that much right now. But eventually we all want to hit the sell button and actually put that money to use. And it’s at that point that we’ll potentially have to pay tax on any gains we’ve made.

The thing is, making all that hopeful growth tax efficient needs to start long before you actually sell up and move on. If you get to that stage, the last thing you want is to be kicking yourself just because you didn’t use the most tax-efficient account to begin with.

Get planning for lower allowances and higher tax rates 

It’s even more important to lend a thought to tax efficiencies when you consider the route most of us want to take is into the higher tax bands at some stage in our working lives. With that prospective rise in salary and tax rate comes a rise in dividend and capital gains tax rate too.

For example, going from being a basic rate taxpayer to being a higher rate taxpayer means potentially paying 33.75% instead of 8.75% on dividends above the allowance. 

That’s even more of an issue for the UK’s highest earners from April 2023 as the additional rate income tax threshold will come down from £150,000 to £125,140. Granted, this bunch might not get a whole lot of sympathy from the rest of the nation’s savers and investors.

But the fact remains that anyone tipping the scales above £125,140 will suddenly find themselves in a 45% income tax band, a 39.35% dividend tax rate, 20% in capital gains tax and staring down the barrel of two successive reductions in investment tax allowances.

Get ISA ready

All of these hits to what investors can earn before tax kicks in mean it’s just got even more important that we make our money as tax efficient as possible. That might mean looking beyond what our current investment gains and dividend income look like, and planning for what could come down the line. 

It’s a harsh reality that a lot of investors investing outside of an ISA will eventually have to stump up tax payments eventually, when they could have just used an ISA instead.

It’s still important to make sure an ISA is right for you though. It could be that you genuinely get nowhere near these allowances or tax thresholds and never plan to. But that’s often the thing with investing. Compounding small amounts and incremental contributions over the years can really build up the snowball effect that good investing is based on.

Whichever way you go, deciding if an ISA suits you or not is at least worth the peace of mind right now.

Important information on SIPPs

‍SIPPs are a pension product designed for people who want to make their own investment decisions. You can normally only access the money from age 55 (set to rise to 57 from 6 April 2028).

Before transferring a pension you should ensure you will not lose valuable guarantees or incur excessive transfer penalties. Pensions are usually transferred as cash so you will be out of the market for a period.

Freetrade does not currently offer drawdown products for our SIPP.



Important information

This should not be read as personal investment advice and individual investors should make their own decisions or seek independent advice.

When you invest, your capital is at risk. The value of your portfolio, and any income you receive, can go down as well as up and you may get back less than you invest. Past performance is not a reliable indicator of future results.

Eligibility to invest into an ISA and the value of tax savings both depend on personal circumstances and all tax rules may change.
