Jeremy Corbyn has challenged Theresa May to publish her tax returns after releasing his own figures that showed he paid £46,074.90 in tax last year.
Mr Corbyn, who published the documents for the fourth time since becoming Labour leader, has said politicians should “lead by example”.
He earned £132,611 in 2017-18, which includes his MP salary and pensions, but had no outside earnings.
The documents reveal the Labour leader was left to pay £6,442 of tax in one go.
The discrepancy – which aides insist was picked up in time and paid in full – emerged in Mr Corbyn’s tax return, which he published yesterday (MON).
A source said Mr Corbyn was on the wrong tax code, which meant he was paying too little tax.
He is paid £43,717 as Leader of the Opposition on which he paid £10,787 tax.
Mr Corbyn earns £79,807 as MP for Islington North and pays £27,870 in tax.
The 69 year old, also received £6,648 in state pension and a Unison union pension of £2,438, on which he paid £975 in tax.
It’s the fourth year in a row Mr Corbyn has released his tax return to the public.
Mr Corbyn, who has been an MP for 36 years, appears to have almost no savings – earning just £1 of interest on them in the whole year.
A good chunk of his income went on charity donations, because he racked up Gift Aid contributions of £1,075 over the years.
After publishing the tax return Mr Corbyn said: “I believe that if we aim to reform our tax system to be more transparent, then politicians must lead by example.
“This is why I have published my tax return for the fourth time since becoming leader of the Labour Party.
“In Government, Labour will crack down on the scourge of tax avoidance and evasion and will put full transparency at the heart of our programme.”
Labour also published Shadow Chancellor John McDonnell’s tax return.
He received a total income of £92,036 including MP’s pay and pensions.
From this income a total of £25,533.00 was deducted in income tax of which £26.60 is repayable.
Mr McDonnell received a £15 dividend from a savings pot he holds in a Credit Union he helped found in his Hayes constituency and holds no other paid positions, stocks or shares, benefits from no trust funds (including blind trusts), did not receive any income from property, and carried out no other paid work during this period.
During the the 2016 Conservative leadership contest Theresa May published a summary.
She has not published any information since then.
Mrs May paid £40,023 in income tax in 2014/15.
She earned £112,426 as an MP and Home Secretary and a further £6,036 in interest and dividends.
Chancellor Philip Hammond has refused to publish his tax return.
