Your 2023 tax guide – what you need to know

With dividend and capital gains tax allowances shrinking, we look at how to pay less tax in 2023.

Important information - This article isn’t personal advice. If you’re not sure whether an investment is right for you please seek advice. If you choose to invest the value of your investment will rise and fall, so you could get back less than you put in.

As the adage goes “nothing is certain in life except death and taxes”.

Given the raft of tax reversals and changes we witnessed last year, you’d be forgiven for questioning the second part of one of Benjamin Franklin’s most famous quotes.

But, while allowances and rates might change, taxes aren’t going anywhere. Whether we like it or not, that means we all need to know what they are, the allowances we can get and how to make the most of them.

The table below highlights some of the main taxes you’re likely to come across.

This article isn’t personal advice. Tax rules can change, and any benefits depend on your circumstances. Tax law can be complex and we can’t show every rule or exemption here. If you’re not sure what’s right for you, ask for tax advice. If you live in Scotland, different tax rates and bands will apply.

How to pay less tax in 2023

Taxes are needed to pay for things like infrastructure, schools, and health services. We all need to pay our fair share. But the government has also put generous tax-saving incentives in place, encouraging us to save for our futures.

One of the most effective and easiest ways to pay less tax is by using your annual ISA allowance.

Every adult UK resident gets an ISA allowance each tax year of £20,000. This lets you save and invest without having to pay UK income and capital gains tax on the returns, helping your money go further.

ISA allowances look safe for now. But as we saw with tectonic tax shifts last year, nothing’s certain.

To avoid getting caught out by the shrinking dividend and capital gains tax allowances, consider using your ISA allowance. If you hold investments outside of an ISA, you’ll probably end up paying more tax.

The new tax year starts on 6 April 2023. So, if you haven’t used this year’s allowance, make sure you don’t miss out.

Use your allowance before it’s too late

*If your non-savings taxable income exceeds the starting rate limit, the starting savings rate won't apply to savings income.

**Your personal allowance is reduced if your income is over £100,000 - by £1 for every £2 above the limit.

Your annual ISA allowances

  • Stocks and Shares ISA allowance: £20,000*
  • Lifetime ISA (LISA): £4,000
  • Junior ISA (JISA): £9,000
