Two million taxpayers facing £800m bill after paying too little tax during the last financial year
Two million taxpayers are being asked for an average of £400 after paying too little
Two million taxpayers will be billed for £800million after paying too little tax during the last financial year, figures reveal.
A further 4.7m paid too much tax and are owed a refund.
For those who did not pay enough tax, officials said the average shortfall is around £400.
This will be collected over the course of the next financial year starting in April through an adjustment to their tax code.
A £400 underpayment would mean an extra tax payment at £33 per month.
HMRC has already written to most who are owed a refund and either sent them a cheque or put the money into their bank account.
The average rebate was also around £400.
HMRC recorded 4.32m overpayments and 1.87m underpayments in 2015 to 2016.
The taxman said it is not always informed promptly of changes in people's circumstances – such as a rise in income – which can mean that the correct amount of tax does not get collected.
