I was asked to help a friend of mine, a (~50 year old) widow, complete her UK tax return recently. In the UK the final deadline for filling in your own tax return is 31 January, and the process these days can all be done online via the taxman’s excellent website. Her finances were illuminating.
What is a rich widow?
This widow’s income is roughly as follows:
- £45k of earnings. She is a freelance creative.
- £25k of investment income, about half of which was taxable (‘unsheltered’). She has about £700k of investments, roughly half in tax-free accounts (ISAs/SIPPs), and half unsheltered. She has no other income-generating assets.
- £10k of contribution to her pension. She is a (non-executive) company director of her ex-husband’s company which doesn’t pay her but does make £10k per year payment into her SIPP.
- £12k of (realised) capital gains last year, all in unsheltered accounts .
This lady’s total income/gains last tax year amounted to over £90k. This puts her in the top 10% of the UK by income, but not the top 5%.
But how much does an ‘average striver’ pay in tax?
Now, before we continue with my widow friend, let’s have a think about ‘average Joanna’, a typical striver in the UK.
Consider Joanna, a (hypothetical) 50 year old who works full-time for the NHS, earning £45k (roughly the London average wage). For a like-for-like comparison, her pension (contribution, from her employer) and (NHS pension investment equivalent) income on top of this would add about £25k to her taxable income, all tax-free.
Joanna pays £6.6k of tax, and £4.4k of national insurance, totalling £11k of tax/NI. This works out as 24% of total gross pay.
How much tax does this ‘rich widow’ making £90k pay?

What total tax/social charges (National Insurance, in the UK) do you think she owes on her annual income/gains?
Before continuing reading, think of a number.
