The Beatles – Taxman Lyrics (lyrics007)
So who are Mr. Wilson and Mr. Heath? Why “one for you, nineteen for me”?
“Taxman,” not a love song but a bitter satire written as well as lead sung by a chronically bitter George Harrison, railing against the huge portion of the Beatles’ earnings due in income tax under jolly Mr. Wilson. – p. 304 of Shout! The Beatles in Their Generation by Philip Norman (2005)
“Taxman” was when I first realised that even though we had started earning money, we were actually giving most of it away in taxes; it was and still is typical. Why should this be so? Are we being punished for something we have forgotten to do? – p. 94 of I, Me, Mine by George Harrison (2007)

Harold Wilson and Edward Heath were, respectively, the British Labour Prime Minister, and Conservative Leader of the Opposition at the time. In the “Anthology 2” version, [they] were replaced with “Anybody got a little money”. – p.496 of The Beatles, by Wikipedians (no year given)
