There's been a lot of confusion over who played lead guitar on this track. Harrison said in his 1977 Crawdaddy
interview: "I helped out such a lot in all the arrangements. There were a lot of tracks though where I played bass. Paul played lead guitar on 'Taxman,' and he played guitar - a good part - on 'Drive My Car."
Jeff Emerick said in his book on recording the Beatles
that Harrison just couldn't get the solo right, so Paul played most of the guitar parts, including the solo. The repeat of the solo at the end of the song was the same "exact" solo by Paul, which Jeff dubbed from the middle of the song to another piece of tape and cut into the fade at the end.
Seth Swirsky, who worked as a staff songwriter before producing the Beatles documentary Beatles Stories
, told Songfacts
: "I think Paul McCartney was one of the greatest guitar players of the '60s. Nobody really recognized him as an electric guitar player, or an acoustic guitar player, but his leads on 'Taxman' and on different songs that you think George played, they ripped. I think George is great, but when Paul played lead on some songs, they tore. They were just very unique. There's no one like Paul McCartney in the history of the world."
