How is cannabis retail tax calculated?
Written from primary sources and checked against them. As of October 21, 2026. How that is done.
Short answer
How is cannabis retail tax calculated?
There is no national cannabis tax. Each state imposes its own charge, on a base it defines, collected by the retailer at the point of sale and stated separately on the receipt, and some states allow a further local charge on top of it.
Bloom has published rates for 13 states so far: Arizona, California, Colorado, Illinois, Maryland, Massachusetts, Michigan, Missouri, Nevada, New Jersey, New York, Oregon and Washington. Each is rendered below from the corpus with the base it applies to, whether it stacks on sales tax, who collects it, when it is filed, and the citation and read date it came with. Calculating it correctly then depends on four other things the rate does not tell you, which are set out underneath.

Each citation is a link to the state's own text. That is the whole offer of this site: do not take the number on trust, open the statute and see whether it says what we say it says.
Read the base on every row before comparing any two of them. A charge on a wholesale price is real money and it is in your cost of goods, but it is levied upstream and never appears on a customer's receipt, so it is not a line the till collects. A table that showed only percentages, without the base beside each one, would invite exactly that mistake, which is why the base is on the card rather than in a footnote.
Four questions the rate does not answer
What is the base? The corpus records the base on every published tax, because a percentage means nothing without it. A rate on the retail sales price and a rate on a weight are different taxes that happen to be written with the same kind of number, and a discount changes the first while leaving the second alone.
Does it stack? 19 of the 40 published taxes stack with sales tax. Where two charges apply, the order they apply in changes the total, because a percentage taken on a subtotal that already includes another percentage is a larger number than two percentages taken on the same base. It is a small difference per transaction and a systematic one per quarter.
Who does not pay it? Exemptions are usually about the customer rather than the product, which means they depend on a document being checked at the moment of the sale. A system that applies an exemption by product category will get it wrong in both directions.
How does it round? Not always the way a spreadsheet rounds, as the next section shows.
Rounding is in the statute, not in your spreadsheet
This is the clearest example on the whole site of why a citation beats a summary. Oregon does not leave the last cent to convention:
"If the tax imposed under this section does not equal an amount calculable to a whole cent, the tax shall be equal to the next higher whole cent."
That is rounding up, in law, on every transaction that does not land on a whole cent. A system using ordinary half up rounding, or the banker's rounding that is the default in a good deal of financial software, will be a cent light on a large share of sales. Nobody notices for a year, and then a reconciliation does.
The same section is where the collection duty and the receipt duty come from. Subsection (1), read the same day, provides that the tax is a direct tax on the consumer, that payment upon retail sale is required, and that it is collected at the point of sale by the retailer at the time at which the retail sale occurs. Subsection (4) requires the amount of the tax to be separately stated on the invoice or receipt provided to the consumer at that time, except as the Department of Revenue provides by rule.
Subsection (5) is worth knowing about even though it will never apply to an honest shop: it prohibits knowingly selling, purchasing, installing, transferring or possessing electronic devices or software programs for the purpose of hiding, removing or falsifying records of retail sales. Sales suppression is legislated against by name, which is a reasonable clue about how seriously the sales record is taken.
Local tax, capped and voted
A state that permits a local charge usually constrains it in the same breath, and the constraints are worth reading before assuming a city rate can be anything a council likes.
"Except as expressly authorized by this section, the authority to impose a tax or fee on the production, processing or sale of marijuana items in this state is vested solely in the Legislative Assembly."
"If the governing body of a city or county adopts an ordinance under this section, the governing body shall refer the measure of the ordinance to the electors of the city or county for approval at the next statewide general election."
"An ordinance adopted under this section may not impose a tax or fee: (a) In excess of three percent; or (b) On a registry identification cardholder or on a designated primary caregiver who is purchasing a marijuana item for a registry identification cardholder."
Three things follow for a retailer. A local rate above the statutory ceiling is not a rate you should be charging. A local tax that was never referred to the electors is on shaky ground. And the local charge carries the same customer exemption as the state one, which means the exemption logic at the till has to reach both lines rather than only the state line.
Who is exempt, and for how much longer
"Notwithstanding ORS 475C.674: (a) A tax is not imposed upon the retail sale of marijuana items in this state to a registry identification cardholder or to a designated primary caregiver who is purchasing a marijuana item for a registry identification cardholder; and (b) A marijuana retailer may not collect the tax imposed under ORS 475C.674 from a consumer if, at the time at which the retail sale of the marijuana item occurs, the consumer provides proof to the marijuana retailer that the consumer: (A) Holds a valid registry identification card under ORS 475C.783; or (B) Holds a valid identification card under ORS 475C.783 (5)(b) and is purchasing the marijuana item for a registry identification cardholder."
Read that carefully, because it is stronger than an exemption a customer may claim. The retailer may not collect the tax where proof is provided at the time of the sale. Charging it anyway is not a customer service problem, it is collecting a tax the statute says is not imposed.
The exemption also has an end date in the text. A note published with the section, read on September 6, 2026, records that it applies to retail sales occurring on or after 1 January 2016 and before 1 January 2028. A sunset in the text as it currently stands is not a prediction that it will lapse, and it is exactly the kind of thing a shop wants to know about in advance rather than in the week it happens.
Practically, the exemption depends on a document being checked at the moment of the sale and on that check leaving a record. Which makes it a purchase limits problem as much as a tax problem: see how much you may sell one customer, where the same card decides a different ceiling.
The record outlives the sale, on its own clock
"A marijuana retailer shall keep receipts, invoices and other pertinent records related to retail sales of marijuana items in the form required by the Department of Revenue. Each record shall be preserved for five years from the time to which the record relates, or for as long as the marijuana retailer retains the marijuana items to which the record relates, whichever is later."
"The department or its authorized representative, upon oral or written demand, may make examinations of the books, papers, records and equipment of persons making retail sales of marijuana items and any other investigations as the department deems necessary."
Two details in there catch people out. The retention clock is not the same as the licensing retention clock, so a shop deleting records on the shorter of the two is deleting tax records early. And the demand may be oral, which means the practical readiness question is not whether the records exist somewhere but whether they can be produced quickly by whoever is standing in the shop that day.
What that looks like in practice, and what else gets asked for, is on what a cannabis inspection asks for.
The federal layer, briefly and carefully
State tax is collected from the customer. The federal issue is a different thing entirely: it is about what a cannabis business may deduct from its own income, and it is the reason shops with healthy margins can post an effective rate that looks impossible.
"Businesses that traffic marijuana in contravention of federal or state law are subject to the limitations of Internal Revenue Code (IRC) Section 280E."
That sentence is the whole of what the agency's own page states on the point. It does not set out what the limitations are, and this page is not going to fill the gap from memory. Federal tax treatment of a cannabis business is a question for an accountant who works in the industry, it changes with litigation and with policy, and Bloom has published nothing about it.
Where this page stops
Questions people ask next
- Is there a national cannabis tax rate?
- No. Each state sets its own charge, on a base it defines, and some allow a further local charge on top. Bloom publishes the state level retail rates it has verified, with the citation and the day the source was read, so the figure can be checked against the state's own text rather than against a summary somewhere.
- Does cannabis tax stack on top of ordinary sales tax?
- Sometimes, and the corpus records it as a field on each published tax rather than as a general rule, because getting it wrong is a receipt error on every transaction. Where a tax does stack, the order of application matters as well, since a percentage of a percentage is not the same number as two percentages of the base.
- How is the tax rounded?
- By whatever the statute says, and it is not always the arithmetic default. Oregon's is explicit: ORS 475C.674(3) provides that if the tax does not equal an amount calculable to a whole cent, the tax is equal to the next higher whole cent. That is rounding up, written into law, and a system using ordinary rounding will be wrong on a large share of transactions by a cent.
- Are medical patients exempt?
- In Oregon a tax is not imposed on a retail sale to a registry identification cardholder or to a designated primary caregiver purchasing for one, and the retailer may not collect it where the consumer provides proof at the time of the sale. The exemption is written to apply to sales occurring before 1 January 2028, so it has an end date in the text as it currently stands.
- Can a city add its own cannabis tax?
- Where the state permits it, and usually on terms. In Oregon the authority to tax cannabis is vested solely in the Legislative Assembly except as that section allows, a city or county ordinance has to be referred to the electors at a statewide general election, the rate may not exceed three percent, and it may not be imposed on a registry identification cardholder.
- How long do tax records have to be kept?
- Longer than most operators expect, and on a different clock from the licensing records. Oregon requires retail sales records to be preserved for five years from the time to which the record relates, or for as long as the retailer holds the items, whichever is later, and the department may examine the books, papers, records and equipment on oral or written demand.
