Trump proposes the biggest tax hike in 30 years

If Trump's 5% tariff on Mexican goods takes effect later this month, the president's trade policies would constitute a bigger tax hike than Bill Clinton’s in 1993.

By the numbers: Tariffs already in place against Mexico will increase revenues by $69 billion, the Tax Foundation estimates — or about 0.32% of GDP. Add in the threatened 5% tax on Mexican imports, and that rises to about 0.40% of GDP.

• That’s more than Clinton’s tax bill in 1993, which brought in revenues of about 0.36% of GDP after the first year, and just shy of George H.W. Bush’s increase in 1990, which amounted to 0.41% of GDP after year 1.

What to watch: If Trump follows through on his threats — 25% on all Chinese and Mexican imports — those revenues would amount to 1.45% of GDP. You’d have to go back to the 1968 tax hike for a bigger revenue measure, per data compiled by the Treasury Department.
