When Congress reconvened after the 1924 elections, it immediately began working on another bill designed to reduce taxes on the highest earners. In February 1926, Coolidge signed the Revenue Act of 1926, which reduced the top marginal rate to 25%. Mellon was extremely pleased by the passage of the act, because, unlike the Revenue Act of 1921 and the Revenue Act of 1924, the Revenue Act of 1926 closely reflected Mellon's proposals. In addition to cutting taxes on top earners, the act also raised the personal exemption for federal income taxes, abolished the gift tax, reduced the estate tax rate, and repealed a provision that had required the public disclosure of federal income tax returns. Meanwhile, the booming economy fostered a $400 million budget surplus in 1926, and the country's national debt dropped from $24 billion in early 1921 to $19.6 billion at the end of fiscal year 1926.
