The US federal excise taxes on beer, wine, and cider are higher for imports than for small/medium domestic producers. US Senator Ron Wyden supports the complaint against Canada. He also introduced the Craft Beverage Modernization and Tax Reform Act in 2015. It and similar bills are expected to be reintroduced in the current session of Congress. They would further tilt the playing field against alcoholic beverage imports in the US. Here is one example from the CBMTRA. It would reduce the excise tax on domestic spirits producers by 80% for the first 100,000 proof gallons/year. The US and EU complained to the WTO about Colombia’s tax rates on booze. In defending against the complaint, Colombia could at least say that the different tax rates are based on the alcohol content, and not on national origin. The US does not even have that argument to justify the uneven playing field of taxing imports at five times the rate of domestic spirits producers.
