What’s next for marijuana tax?

Here in Hawaii, we have an initial group of licensed medical marijuana dispensaries getting ready to open shop, although none have opened to date. This has raised some tax issues before, and some are likely to come up again.

On Election Day 2016, voters in several states legalized marijuana and approved hefty tax rates to go with it. California, Massachusetts and Nevada all approved marijuana with a special tax rate of 15 percent. In Maine, the ballot measure squeaked by with a special tax rate of 10 percent.

A marijuana measure also was on the ballot in Arizona, together with a 15 percent tax rate, but was rejected by voters there. In all these states, the high tax applies to recreational use of marijuana, not medicinal use which was legal in each of these states before the election.

Earlier in 2016, lawmakers decided that the federal income tax rule prohibiting any deductions for dealers in controlled substances would not apply to licensed medical marijuana dispensaries.

The same law also said that our General Excise Tax exemption for medicine would not apply either. This may mean that our legislators are considering a special, higher GET rate for marijuana, but haven’t decided upon that rate yet. Indeed, one of the versions of the bill that legalized marijuana dispensaries, in fact, carried a 25 percent special GET rate.

If that’s what lawmakers want to do, they should keep in mind that the tax is imposed on the business, and if the business chooses to pass it on to the consumer that part is also taxed, requiring a higher passed-on rate if the business just wants to come out even.

That’s why Neighbor Island consumers see a line item for 4.166 percent tax on their bills although their GET rate is 4 percent, and Honolulu consumers get 4.712 percent passed on to them when their tax rate is 4.5 percent.

When the tax rate gets higher, the difference between the legal rate and the pass-on rate goes up as well, and dramatically so. To see the reason why, suppose the GET rate is 25 percent, as lawmakers proposed earlier, and we have a dispensary that needs to clear $300 after taxes.

The dispensary can’t simply charge its customer 25 percent of $300 = $75 as tax, because the dispensary will be required to pay 25 percent of the total charge of $375, which is $93.75. That would leave the dispensary almost $20 short. Instead, the dispensary must charge $100 in tax.

Then the total sales price is $300 + $100 = $400, and the tax is 25 percent of $400 = $100, leaving the dispensary with the $300 needed.

Thus, if we have a special GET rate for marijuana at 25 percent of sales, the passed-on rate would be 33.333 percent! If lawmakers decide to enact a 15 percent rate, which was passed by most of the ballot measure states this time, the passed-on rate would be 17.647 percent, adding more than 2½ percent to an already astronomical rate. With a 10 percent rate, the passed-on rate would be 11.111 percent, adding more than one whole percentage point.

Again, this tax would be on medical marijuana, not marijuana for recreational use. If the former is taxed while medicine is not, then how much tax will apply to recreational use if it is legalized?

This, of course, just goes to show how different our GET is from the sales taxes that are prevalent on the Mainland. We aren’t in Kansas, Dorothy! Lawmakers who are considering such changes would be well advised to keep these differences in mind.
