A couple interesting things: If you buy a 1.75L bottle of the cheapest vodka at Lakeview Binny's (Crown Russe, $8.99 with Binnys card) there's $6.35 of state and federal tax. You'll also pay $2.40 of city and county tax but that's tacked on to your bill along with $1.02 of sales tax. So, out of a grand total of $12.41 there's $2.64 to make vodka.
Suppose you are accustomed to the finer things in life. A smaller 750ml bottle of Harlan D. Wheatley's CLIX vodka, distilled 159 times, has $2.78 of state and federal tax along with $1.04 of city and county tax. The $279.99 price does command $28.70 in sales tax, and the total bill of $309.73 includes $32.52 of tax, leaving $277.21 for the vodka. Heck, that's less than $2 per distilling!
The upshot of all this is that the current liquor tax scheme, being a flat tax per gallon or proof gallon, is regressive. Poor folks drinking rotgut pay proportionally far more tax than rich folks sipping the finest.
Now, on to the tax increase. At 94¢ per gallon, a 1.5oz shot of liquor's tax will increase just over a penny. Even less for a can of beer with a 10¢/gallon increase. And that's true whether it's PBR or Remy Martin Louis XIII. I truly doubt that a penny per drink will make much difference in where customers decide to imbibe.
A fairer scheme that could generate much more revenue would be a proportional or, better yet, a progressive tax that would hit less-price-sensitive drinkers much harder. One way to do that would be to impose a much higher "luxury" surtax, say $3 per gallon on beer selling for more than $8/12oz, $20/gallon on wine selling for more than $75/bottle, and $100/gallon on liquors retailing for more than $15 per drink. Sound like a lot? It's less than the sales tax. Such a scheme is also anti-inflationary as it encourages sellers to keep prices below the surtax line, or substitute less expensive goods.
