Key takeaways
- States tax vape products in three main ways: per milliliter of liquid, as a percentage of wholesale cost, or as a percentage of the retail price at the register.
- The tax model determines who remits the tax and whether it appears on the customer's receipt, so your POS setup has to match it.
- Online orders are generally taxed under the rules of the buyer's state, which often means running several tax models in one checkout.
- Clean SKU data, distributor invoices and sales reports broken out by tax category are your best defense in a vape tax audit.
If you sell e-liquid, pods or disposables in more than one location, or ship to customers in other states, vape tax by state is one of the hardest parts of running the business. States don't agree on what to tax, how to measure it or who pays. This guide covers the three common tax models, how they treat open and closed systems, who owes the tax, how to configure each in your POS and online checkout, and what records to keep for an audit.
This article is general information, not tax or legal advice. Vape tax rates, definitions and filing rules change often and vary by state and locality. Confirm current requirements with your state revenue department and a qualified tax professional.
Vape Tax by State: Three Ways States Tax Vape Products
Most state vape taxes follow one of three models. Some states combine them, for example a per-mL tax on liquid plus a percentage tax on devices. Local jurisdictions in some states add their own taxes on top.
| Tax Model | What the Tax Is Based On | Usually Collected By | Shows on Customer Receipt? |
|---|---|---|---|
| Per-mL (volume-based) | Milliliters of e-liquid in the product | Distributor or retailer, depending on state | Sometimes; often built into the price |
| Percentage of wholesale | Wholesale cost or price paid by the retailer | Distributor, wholesaler or first in-state seller | Usually not; it's embedded in your cost |
| Retail-level excise | Retail selling price | Retailer at the register | Yes, typically as its own line |
Per-mL taxes charge a flat amount for each milliliter of liquid. The tax on a bottle depends on its size, not its price.
Wholesale taxes charge a percentage of the wholesale price. A premium e-liquid costs you more tax than a budget brand of the same size.
Retail-level excise taxes work more like sales tax. You charge a percentage of the selling price at checkout, usually on top of regular sales tax. States differ on whether sales tax applies to the excise amount itself.
Illustrative Comparison
The rates below are made up to show the math. They are not any state's actual rates.
- Per-mL (illustrative $0.10 per mL): A 60 mL bottle carries $6.00 in tax. A 100 mL bottle carries $10.00, whatever the price.
- Wholesale (illustrative 20%): A bottle you buy for $10 wholesale carries $2.00 in tax, which is built into your invoice cost.
- Retail excise (illustrative 10%): A $25 bottle carries $2.50 in excise tax at the register, plus any applicable sales tax.
The same product can be taxed very differently depending on where it's sold. That's why a single tax setting won't work for multistate retailers.
Per-mL Vape Tax on Open vs. Closed Systems
Per-mL taxes look simple until you apply them to a real vape shop shelf. Many states define open systems and closed systems differently, and some tax them at different rates or under different models.
Open Systems: Bottled E-Liquid
Open-system products are refillable: bottled e-liquid, nic salts and shortfills that customers pour into tanks or refillable pods. Per-mL tax on these is usually easy because the volume is printed on the bottle. Watch for:
- Bottle size variety. A store selling 30 mL, 60 mL and 100 mL versions of one flavor needs a separate tax amount for each size.
- Shortfills and nicotine shots. If a shortfill bottle comes with a separate nicotine shot, find out whether your state taxes the shot's volume too.
- Zero-nicotine liquid. Some states tax liquid whether or not it contains nicotine. Others tie the tax to nicotine content. Don't assume zero-nic is exempt.
Closed Systems: Pods, Cartridges and Disposables
Closed systems come prefilled. In some states the tax depends on liquid volume. In others it's a flat amount per unit or a percentage of price. The common complications are:
- Multipacks. A four-pack of pods is four units of liquid. Your per-mL tax has to use total volume, not one pod.
- Disposables. Use the volume on the label, not a guess from puff count.
- Products where volume is hard to find. If the packaging doesn't clearly show volume, ask your distributor for spec sheets before the product goes on the shelf.
Devices and Hardware
Mods, tanks, coils and empty refillable pods contain no liquid. A per-mL tax may not reach them, but a wholesale or retail excise tax might. Starter kits that include a bottle of e-liquid can be taxed partly by volume and partly by price. Ask your state how bundled kits should be split.
Product eligibility affects taxes too. Some states restrict which products you can sell at all. See our guides to state vape registry laws and selling only listed products and locking banned flavor SKUs in your POS.
Who Pays a Vape Wholesale Tax: Distributor, Retailer or Customer
The customer pays the tax in the end, through the price or a line on the receipt. The legal question is who has to collect and remit it. The answer shapes your bookkeeping.
- Distributor-level taxes. Under many wholesale and some per-mL models, the licensed distributor or first in-state seller pays the tax and passes it to you in your cost. Your job is to buy from licensed sources and keep invoices that show the tax was paid.
- Retailer liability for untaxed product. If you buy from an out-of-state supplier that isn't licensed in your state, or import directly, the tax obligation may fall on you. This catches many shops off guard.
- Retail-level taxes. You collect the tax at the register and remit it on a schedule your state sets, often through a separate excise return.
Find out whether your state requires a separate license or permit to sell vapor products, to distribute them, or both. If your business wholesales to other shops as well as selling retail, you may have obligations at both levels.
Vape Excise Tax POS Setup: Configuring Taxes at the Register
Your POS has to calculate the correct tax on every product for every location. A good setup starts with your item data, not your tax settings.
Step 1: Build Tax-Ready SKU Data
For every vape SKU, record:
- System type: open liquid, closed pod or cartridge, disposable, device or accessory
- Liquid volume in mL per sellable unit, with multipacks totaled
- Nicotine content, if your state's tax or restrictions depend on it
- Wholesale cost, if you owe wholesale tax on any untaxed purchases
- Tax category, a label you'll map to tax rules (for example, "Open liquid – per mL")
Step 2: Match the Tax Type to Your POS Capabilities
Percentage taxes are easy because every POS handles them. Per-mL taxes are harder because they're a flat amount per item that changes with volume. Before you configure anything, check:
- Can your POS apply a fixed-dollar tax per item, or only percentages?
- Can one item carry more than one tax, such as excise plus sales tax?
- Can tax rules differ by location if you operate stores in more than one state or city?
- Does the receipt show each tax separately when your state requires it?
If your system only supports percentage taxes, don't fudge the numbers by converting a per-mL tax into an approximate percentage. A $15 bottle and a $30 bottle of the same size owe the same per-mL tax. A percentage can't reproduce that. Ask your provider whether a flat-amount tax or a per-item fee can be set up and labeled correctly. If you're shopping for hardware, MannyPay offers POS systems for vape shops from brands including Clover, Valor, Dejavoo and PAX. Confirm that any system you choose supports the tax types your states use.
Step 3: Test Before You Go Live
Run test transactions for each tax category:
- A single open-system bottle in each size you carry
- A pod multipack
- A disposable
- A starter kit with included liquid
- A device with no liquid
- A mixed basket with all of the above
- A return or exchange, to confirm the tax reverses correctly
Step 4: Check How Card Pricing Programs Interact With Tax
If you use a dual pricing program, a cash discount or surcharging where permitted, confirm which price your state uses as the tax base for percentage-based taxes. Also confirm that your receipt shows taxes and the card or cash price the way state rules and card network rules require. This varies, so ask your tax advisor and your processor before you launch.
Charging the Right Tax on Online Orders by State
Online vape sales add another layer. The buyer's state generally sets the rules, so one store may need to apply per-mL tax to one order, retail excise to the next and nothing extra to a third. Some states also require remote sellers to register, collect and file excise returns. Some prohibit direct-to-consumer shipping of vapor products entirely.
Federal rules also govern how vape products can be shipped to consumers, separately from state taxes. Our guide to federal and carrier shipping rules for vape products covers the shipping side in detail. Confirm your obligations with a qualified professional before you ship across state lines.
Practical Setup for Your Online Store
- Block states you can't ship to at the address stage of checkout, before payment.
- Store mL and system type as product attributes in your platform so tax rules can read them.
- Check your sales tax app. Many sales tax apps handle percentage sales tax well but don't calculate per-mL vape excise. You may need a specialized tool or custom rules.
- Use the same tax categories online and in-store so your reports reconcile.
Your payment gateway matters too, since many mainstream processors restrict vape sales. See our breakdown of the best payment gateway for an online vape store. MannyPay supports e-commerce integrations including Shopify and WooCommerce.
Recordkeeping for Vape Tax Audits
Excise audits often come down to reconciling what you bought against what you sold. Organized records can turn a painful audit into a routine one.
| Record | Why It Matters |
|---|---|
| Distributor invoices showing tax paid | Proves tax was paid upstream on wholesale or distributor-level models |
| Supplier license or permit numbers | Shows you bought from licensed sources |
| SKU list with mL, system type and tax category | Supports how each item was taxed |
| Sales reports by tax category and location | Ties your filed returns to actual sales |
| Online orders by destination state | Supports remote-seller filings and state-level collection |
| Returns, exchanges and voids | Explains differences between gross sales and taxable sales |
| Filed excise returns and payment confirmations | Proves timely filing and payment |
A few habits help:
- Reconcile monthly. Compare tax collected in your POS and online store against what you filed.
- Snapshot your tax settings whenever rates change. Auditors may ask what rate applied on a given date.
- Ask about record retention periods. Requirements vary by state, so confirm how long you must keep each record type.
- Watch for rate changes. When a new tax takes effect, ask whether any tax applies to inventory you already have on hand.
Next Steps for Your Vape Shop
- List every state where you sell, in person and online, and confirm each state's current tax model with its revenue department.
- Clean up your SKU data so every product has volume, system type and tax category.
- Confirm your POS and e-commerce platform can handle flat per-item taxes, multiple taxes per item and location-based rules.
- Test every product type before rates go live, and reconcile your filings monthly.
- Review your setup with a tax professional who works with tobacco and vapor product businesses.
Taxes are only part of the cost of running a vape shop. Card processing for vape merchants is typically underwritten as high-risk, so it helps to know what vape shops should pay in processing fees.
