Applicable Statutes

Tax exemptions for medical cannabis

The 2015 Legislature enacted seven tax preferences for medical cannabis: six sales and use tax exemptions for medical cannabis patients and cooperatives, and a business and occupation (B&O) tax exemption for medical cannabis cooperatives.

The preferences vary in customer eligibility requirements, intended beneficiaries, and qualifying purchases and activities.

The preferences have no expiration date.

Usage limited in part by availability of medically endorsed retailers

Six of the seven preferences require access to a retailer with a medical endorsement from the Liquor and Cannabis Board. Medical endorsement is voluntary for licensed retailers. Washington has 275 medically endorsed retailers in 32 counties. These retailers can register eligible customers in the medical cannabis authorization database and make tax-exempt sales. In fiscal year 2020, 205 retailers made tax-exempt sales. Some retailers, including medically endorsed retailers, offer retail discounts in lieu of the medical cannabis sales tax exemptions. It is unclear how often customers make purchases with discounts instead of the preferences.

Largest tax preference subject to updated guidance

Over 87% of beneficiary savings for the medical cannabis tax preferences have been realized under one retail sales tax preference. In 2019, the Legislature modified the tax preference to refer to DOH-compliant products. It is unclear how pending taxpayer guidance will affect future beneficiary savings.

Recommendations

Legislative Auditor's Recommendation: Continue

The Legislature should continue the preferences because they provide tax relief to medical cannabis patients.

The Department of Revenue and the Department of Health should update guidance to reflect 2019 statutory changes.

You can find more information in Recommendations.

Commissioners' Recommendation

The Commission endorses the Legislative Auditor's recommendation with comment. Testimony suggests the state should consider reviewing the definitions and guidelines associated with medical cannabis. The Legislature may want to evaluate approaches used in other states, such as Colorado, and consider whether and to what extent Washington’s laws can be altered to better meet patient needs. The Legislature may find that additional interventions may be needed to address the issues raised in testimony. These issues largely revolve around quality and price differentials between the regulated and unregulated market.

Proposed Final Report: Medical Cannabis Tax Preferences

REVIEW Details

1. Seven preferences for medical cannabis

Seven preferences provide tax relief for medical cannabis purchases and cooperatives

Six preferences provide exemptions from sales and use tax on retail purchases of cannabis and cannabis-based products, and one preference provides an exemption from the B&O tax for medical cannabis cooperativesMedical cannabis cooperatives allow up to four medical cannabis patients or their designated provider to grow cannabis for the patients’ personal use.. The preferences were enacted in 2015, and have no expiration date.

Three agencies are involved in medical cannabis regulation or taxation. The Department of Revenue (DOR) collects retail sales and use taxes and provides guidance to taxpayers. The Department of Health (DOH) administers the medical authorization database, licenses and regulates the medical cannabis consultant certificate, and establishes product quality standards for products that may be beneficial for medical use. The Liquor and Cannabis Board (LCB) licenses and regulates cannabis producers, processors, and retailers, and collects the marijuana excise tax.

Preferences limited to certain retailers, customers, and products

When the 2015 Legislature created the preferences, it stated its intent to provide tax relief to medical cannabis patients and cooperatives under certain circumstances. The preferences vary in customer eligibility requirements, intended beneficiaries, and qualifying purchases and activities. See Section 3 for beneficiary savings for each preference.

Licensed retailers may receive medical endorsements from the Liquor and Cannabis Board

Licensed retailers may request a medical endorsement from LCB. To hold an endorsement in good standing (WAC 314-55-080), a retailer must, among other requirements:

  • Employ a cannabis consultant certified by DOH.
  • Demonstrate the ability to register patients in the medical cannabis patient database.
  • Issue recognition cards to registered patients and their providers.
  • Carry a representative assortment of cannabis products for registered patients and designated providers.

While all requirements are subject to enforcement, LCB states it only enforces the requirement to employ certified consultants.

Patients and their designated providers may register as recognition cardholders

202 retailers issued recognition cards in fiscal year 2018, 195 in fiscal year 2019, and 188 in fiscal year 2020.
Source: JLARC staff analysis of Department of Health data.

Five of the preferences are restricted to patients registered in the medical cannabis authorization database or their designated provider. Collectively, these people are called "recognition cardholders," because they are issued a recognition card when they register in the database. To register, patients or designated providers must visit a medically endorsed retailer and request registration from a certified consultant.

The number of retailers issuing cards and the number of cards issued have declined in the past three years. According to state agency staff and stakeholders, the reason for this decline is unknown.

Two preferences are available to all customers. These apply to products that do not have significant psychoactive effects due to their low concentrations of THCThe principal psychoactive compound in cannabis. .

Three preferences are available to cooperatives and their members. Medical cannabis cooperatives allow up to four medical cannabis patients or their designated providers to grow cannabis for the patients’ personal use. To register in a cooperative, a patient or designated provider must obtain a recognition card through a medically endorsed retailer. There are currently 12 cooperatives in six counties.

Department of Health's compliant product standards apply to two preferences

Two preferences apply to sales of products that meet DOH's compliant product standards. These standards are optional criteria that cannabis producers and processors test their products against, in addition to the LCB standards for all cannabis products. Current DOH standards establish maximum allowable levels for certain heavy metals and pesticides which are not included in the LCB testing standards. The compliant product standards are intended to provide quality assurances for products that may be used to address medical conditions.

DOH-compliant products fall into three categories: General Use, High THC, and High CBD Low THC Ratio.

2. Retailer availability limits use

Availability of medically endorsed retailers is one factor that limits preference use

Six of the seven preferences require access to a medically endorsed retailer

Six of the seven preferences apply to sales by medically endorsed retailersCannabis retailers meeting certain requirements may be endorsed by the Liquor and Cannabis Board.. Cannabis retailers are not required to obtain a medical endorsement, which means these preferences may not be available to eligible customers at all retail locations.

Medically endorsed retailers are located in 32 of 39 counties

There are 510 licensed cannabis retailers in 38 counties. Of these, 275 retailers (54%) have medical endorsements. Seven counties have no medically endorsed retailers.

There are no medically endorsed retailers in Lewis, Skamania, Lincoln, Franklin, Garfield, Pend Oreille, and San Juan counties.

Of the 275 currently medically endorsed retailers, 188 issued recognition cards in fiscal year 2020 to patients or their designated providers. This includes the re-issuance of lost or expired cards.

205 endorsed retailers made tax-exempt sales in calendar year 2020. Of Washington’s 38 counties with licensed retailers, 32 counties had a retailer making tax-exempt sales.

Further information about retailers and cooperatives in each county is available in the Appendix.

Exhibit 2.2: 205 of Washington's 510 licensed cannabis retailers made tax exempt sales in 2020

205 medically endorsed retailers made exempt sales, 70 medically endorsed retailers did not make exempt sales, and 235 retailers were licensed but not medically endorsed.

Source: JLARC staff analysis of the Liquor and Cannabis Board's Marijuana Traceability Database.

Some retailers offer discounts in lieu of sales tax preferences

Department of Revenue (DOR) audit records and stakeholder interviews indicate that some retailers, including those without medical cannabis endorsements, offer discounts to recognition cardholders for purchases eligible for tax preferences. These are discounts to the retail sales prices, upon which sales and use tax is still collected. However, purchases from medically endorsed retailers qualify for a sales tax exemption, and should not be taxed. Patients paying sales and use tax on some of these purchases may be eligible to request refunds from the retailers or DOR, in accordance with WAC 458-20-229, if they believe the sales tax was paid in error.

Some retailers indicated they provide a discount in lieu of the tax preference due to discomfort with handling medical records, the cost of required equipment, and retention of qualified cannabis consultants required for a medical endorsement. It is unclear how many retailers offer discounts rather than make tax-exempt sales and the total value of discounts offered is unknown.

3. 2019 change could affect savings

Beneficiaries will save an estimated $4.9 million in the 2021-23 biennium. Most savings are realized under a recently modified preference for which guidance is not yet updated.

Beneficiary savings in fiscal year 2020 for all seven tax preferences are $1.79 million. Over 87% of the beneficiary savings were realized under a single preference: Medical Cannabis Sold to Qualifying Patients.

Exhibit 3.1: One preference accounts for over 87% of FY 2020 beneficiary savings
Preference Name Beneficiary Savings, FY 2020
Medical Cannabis Sold to Qualifying Patients $1.57 million
Low THC Products Sold to Qualifying Patients $83,000
Cannabis with Low THC High CBD Ratio $113,000
Topical THC Sales by Health Care Professionals ConfidentialThree or fewer taxpayers deducted sales under this preference and beneficiary savings are confidential.
Medical Cannabis Produced and Used by Cooperative Members $8,400
Resources and Labor Contributed by Medical Cannabis Cooperative Members $16,200
Cannabis Cooperatives $800
Total $1.79 million

2019 statute changed products eligible for the Medical Cannabis Sold to Qualifying Patients sales tax exemption, which has the greatest beneficiary savings. Future savings could be affected.

The 2019 Legislature passed the Marijuana Product Labeling Act (ESSB 5298). The bill restricts cannabis product labels from making medical claims, and clarifies that the Medical Cannabis Sold to Qualifying Patients preference applies specifically to sales of products that meet the Department of Health’s (DOH) compliant product standardsStandards that test cannabis products for certain heavy metals and pesticides.. This legislation altered the language of the cannabis tax preference with the highest beneficiary savings, potentially affecting its use.

Preference previously applied to all recognition cardholder purchases

Prior to the 2019 statutory change, the Medical Cannabis Sold to Qualifying Patients sales tax exemption applied to all purchases made by recognition cardholdersMedical cannabis patients or their designated providers who are registered in the medical cannabis authorization database. of cannabis products identified by DOH as beneficial for medical use.

DOH determined in 2015 that because cannabis is federally classified as a Schedule 1 controlled substance, there was insufficient evidence to identify particular products as beneficial for medical use. Due to this lack of evidence, DOH deferred to patients and their healthcare providers to determine which products are medically beneficial. A 2016 Department of Revenue (DOR) Special Notice to taxpayers indicated that all cannabis products purchased by recognition cardholders from medically endorsed retailers were presumed to be medically beneficial and exempt from sales and use tax under this preference.

Preference administration has not changed

Effective January 1, 2020, the Marijuana Product Labeling Act specified that the preference applies to products meeting DOH's compliant product standards. StatuteRCW 69.50.375 requires medically endorsed retailers to carry a representative assortment of DOH-compliant products. The Liquor and Cannabis Board (LCB) stated that this requirement has not been enforced. Beneficiary savings in fiscal year 2020 for purchases of products labeled as DOH-compliant were $6,895, which is less than 1% of the $1.57 million of claimed sales tax savings that year.

DOH and DOR have not updated guidance to medically endorsed retailers or the public since the 2019 statutory change. Medically endorsed retailers have continued not to collect sales tax on purchases by recognition cardholders, regardless of the products' compliance with DOH standards. DOR stated that it is working with DOH, and DOH is in the process of updating public guidance for compliant cannabis products.

Future biennial savings estimated to be $4.9 million

The estimates of future beneficiary savings shown below assumes there is no change in guidance for the Medical Cannabis Sold to Qualifying Patients preference. However, if new guidance limits qualifying purchases, future savings could be affected.

4. Optional database registration unique to WA

Optional registration in the patient database sets these preferences apart from other preferences and states

Preferences for other medical necessities do not require beneficiaries to register in a database

A 2013 JLARC report reviewed retail sales and use tax exemptions for medical necessities. Medical necessities are medical products the Legislature defined as necessary for health, or products that health professionals recommend or order for patients. This includes menstrual products, insulin, and dialysis equipment.

Five of the seven medical cannabis tax preferences require beneficiaries to register in the medical cannabis patient database. Tax preferences for other medical necessities may require prescriptions or authorizations from healthcare provider, but none require beneficiaries to register in a database.

Patients who are not registered in the database may purchase most cannabis products, but are ineligible for the tax preferences that require registration. It is unknown how many patients with medical cannabis authorizations from their health care provider do not register in the database.

Unlike peer states, patient database registration is optional in Washington

JLARC staff identified eleven other statesAlaska, Arizona, California, Colorado, Illinois, Maine, Massachusetts, Michigan, Montana, Nevada, and Oregon. that allow sales of medical and recreational cannabis.

The eleven peer states either do not tax medical cannabis or tax it at a lower rate than recreational cannabis. These states also vary in credentialing requirements for cannabis retailers. Some states require medical retailers to serve only verified medical customers, or may restrict certain types of products to verified medical patients. Others allow for recreational and medical sales in the same location, but may require inventories and points-of-sale to be separate.

Most of these states require medical cannabis patients to register in a database as a condition of eligibility for medical cannabis tax preferences. Washington is the only state in which database registration in a patient database is optional. Patients who are not registered in Washington's database are unable to claim five of the seven tax preferences.
