However, I hadn't really thought about how much tax our earning (and spending) results in - the answer is quite amazing really.
The following is based on an idea from a recent Moneywise article - developed a little further.
Here's a simple question: assuming you are a basic rate taxpayer, how much does the Taxman (in my case, the UK Taxman) receive for every after-tax £1 that your spend?
If you're a UK basic-rate taxpayer, for every £1 you earn over the £7,475 personal allowance, the taxman will get 20p in income tax. On top of that, HM Revenue & Customs (HMRC) will receive 12p in employee national insurance (NI) and a further 13.8p in employer NI. That's a total of 45.8p so far for the taxman, 32p of which has come out of your pocket - so your original £1 has fallen to an after-tax 68p.
If you spend that taxed £1 on something that is subject to VAT, HMRC will get a further 20p. So you will personally have paid 67p in tax for each £1 spent.
And with the employer's NI payment, the Taxman will have pocketed an amazing 87p for every after-tax £1 that you spend. The tax take is even higher for higher-rate income tax payers.
Amazing. And a good reason to take full advantage of any tax allowances that you are entitled to - as we encourage here at the DIY Income Investor.
Update: an article in This is Money reported that the Taxman takes nearly half of a typical family's income.
