To finance the Civil War, the Union government levied taxes on products, companies, and incomes. How income taxes have – and haven't – changed in the 150 years since.

The Civil War, which began on the twelfth of April 150 years ago, transformed America financially as it did in so many other ways.
Abraham Lincoln instituted America's first income tax in 1862, as he searched for money that would enable the union to wage and win the war. Along with this move came tax-code complexity and a new agency called the Bureau of Internal Revenue.
Some 150 years later, things have changed ... and things have stayed the same.
Since the Civil War, the income tax has been declared unconstitutional, then legalized by an amendment to the US Constitution, then expanded, then greatly reduced.
But after 150 years, Americans still owe income taxes – due April 18 this year. They still struggle with arcane tax rules. And they still worry about the far-reaching tentacles of the agency now known as the Internal Revenue Service.
