The Tax Incidence and Tax Pass-Through of Smokeless Tobacco in the US.

Background: States adopt different tax bases for smokeless tobacco (SLT), making tax incidence on SLT not directly comparable across states. In addition, how taxes are passed through to SLT prices among states that impose specific taxes, and whether the pass-through rates for SLT are affected by the uptake and evolution of e-cigarettes, is unknown.

Objective: This study will calculate the tax incidence on SLT and investigate how SLT taxes are passed to prices at the 25th, 50th, and 75th percentile levels, as well as whether these pass-through rates vary by e-cigarette uptake and evolution.

Methods: We regressed SLT prices on specific taxes using ordinary least square regressions while controlling for state-, year-, and quarter-fixed effects. We then tested the difference in tax pass-through rates by different periods.

Findings: The average tax incidence on chewing tobacco, moist snuff, dry snuff, and snus was 22%, 22%, 23%, and 20%, respectively. For moist snuff, taxes were fully passed to prices at the 25th and 50th percentiles (rate = 1.01, < 0.001) and overly passed to prices at the 75th percentile (rate = 1.25, < 0.001). The e-cigarette uptake and evolution significantly raised taxes by 13 cents and 14 cents per ounce, respectively, for moist snuff at the 75th percentile prices ( < 0.05).

Conclusions: If harm is considered a criterion for taxing tobacco products, the tax incidence on SLT could be further increased. Considering that lower-priced SLT have lower tax pass-through rates, price promotion restrictions and minimum pricing laws may be needed to increase the cost of lower-priced products. Additionally, we observed that tobacco companies tended to increase tax pass-through for premium SLT products as e-cigarettes gained popularity, which may indicate a strategic response to shifting consumer preferences.
