Tait was born in Edinburgh in 1861, the eldest son of Scottish mathematical physicist Peter Guthrie Tait and Margaret Archer Porter. He was educated at the Edinburgh Academy from 1871 to 1877 before studying Law at Peterhouse, Cambridge, from 1880. He received his BA in 1884, and on 7 November the same year was admitted at Lincoln's Inn. Tait was called to The Bar on 25 April 1888 and was awarded his MA in 1890. In 1890 he travelled to India and took up a post in the Government Education Department at Mysore, Karnataka. He became Professor of Languages and vice-principal of Central College of Bangalore, and in 1908 he was made Principal of the College. He was commissioned a Captain in the Bangalore Rifle Volunteers on 31 October 1893. He resigned his commission as a Lieutenant-Colonel 12 July 1917. He was awarded the Volunteer Decoration for his long service. In 1937 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were D'Arcy Wentworth Thompson, William Peddie, Arthur Crichton Mitchell and Sir Edmund Taylor Whittaker. In his later life, Tait became a keen student of the works of Sir Walter Scott, and assisted the editors of the centenary edition of the Letters of Sir Walter Scott, and brought out a revised text of The Journal of Sir Walter Scott based on the original manuscript. He died in Edinburgh in 1945. He is buried next to his parents in the churchyard of St John's Episcopal Church, Edinburgh.

Rugby career
Tait first came to note as a rugby player when he represented his college team,. In 1880 he was selected for the Scotland national team, in a Home Nations friendly against Ireland. Scotland were easy victors, winning by three goals to nil; but despite the victory Tait was not part of the Scotland team that faced England for the Calcutta Cup just two weeks later. In 1880, now a freshman at Peterhouse, Tait was selected for the Cambridge University team. At the end of the year Tait was part of the Cambridge team to face Oxford University in the annual Varsity Match, now played at Blackheath. This was Tait's first sporting 'Blue', and the game ended in a respectful draw. Tait missed the 1881 game, but was back in the team for the 1882, led by fellow Peterhouse student Herbert Fuller. The game was won by Oxford, thanks to a clever try scored by Alan Rotherham. Tait played one final notable game, when in 1885 he was called back into the Scotland side, to once again face Ireland, this time as part of the 1885 Home Nations Championship. The game ended in another Scottish victory, but Tait would not represent his country in rugby again.
Amateur golfer
Tait was also a keen golfer, and in his younger days he taught his younger brother, Frederick Guthrie Tait, the basic techniques of the sport. Before leaving for India, Tait entered several amateur golfing tournaments, and in 1887 reached the semi-final stage of the Amateur Championship at Hoylake; being eventually knocked out by John Ball. Although the tutor of his brothers, Frederick would surpass Tait in style and ability, and Frederick's style "...was neater, more finished, more polished, than Jack's."
