User Guide
Everything you need to configure and operate StickTax on your BigCommerce store.
Last updated: April 2026 · v1.0
Overview
StickTax is a BigCommerce app that calculates cigar excise tax and state sales tax at checkout. It replaces the manual guesswork of cigar-specific tax calculations with an automated engine that runs on every checkout.
General tax providers like Avalara and TaxJar handle sales tax well, but they don't support cigar-specific excise tax methods: per-stick flat rates, MSRP-based percentages, per-stick caps, or combinations of these. StickTax was built specifically for this gap.
What StickTax does
- Calculates cigar excise tax using the correct method for each state (per-stick, MSRP percentage, capped, or combo)
- Calculates state sales tax based on your configured rates
- Distinguishes between singles and boxes, applying the correct stick count for box variants
- Syncs your BigCommerce product catalog automatically
- Logs every tax calculation for reporting and export
What StickTax does not do
- StickTax does not provide tax advice or regulatory guidance
- StickTax does not automatically update rates when tax laws change — you configure and maintain your own rules
- StickTax does not handle tax filing or remittance — it calculates and collects at checkout
- StickTax does not modify your products, inventory, or store settings beyond the tax provider connection
Your responsibility: StickTax provides the calculation engine. You provide the rates. It is your responsibility to ensure your configured rates match current state regulations. We strongly recommend consulting a qualified tax professional.
Requirements
- A BigCommerce store (any plan)
- Products configured with variants for singles and boxes (standard BigCommerce setup)
- Product pricing set to exclusive of tax in BigCommerce settings
- Products assigned to the Default Tax Class (not "Non-taxable")
No code changes required. StickTax works with your existing BigCommerce catalog. You don't need to modify your theme, add custom fields, or change your product structure.
Installation
For step-by-step installation instructions, see the Installation Guide. Here's a summary:
Install StickTax from the BigCommerce App Marketplace. Authorize the requested permissions.
Open StickTax from Apps → My Apps in your BigCommerce control panel.
Sync your catalog, configure your state tax rules, and set up profile classes for your box sizes.
StickTax begins calculating tax at checkout as soon as you have at least one active excise or sales tax rule and a synced catalog.
First-Time Setup Checklist
After installation, complete these steps in order:
- Sync your catalog — Go to the Products tab and click "Sync Catalog." This pulls all your products and variants from BigCommerce.
- Create profile classes — Go to Profile Classes and add entries for each box size you sell (e.g. "Box of 20", "Box of 24"). This tells StickTax how many sticks are in each box.
- Assign classes to box variants — Go back to Products and assign the correct profile class to each box variant using the dropdown in the Class column.
- Set MSRP values — For any state using MSRP-based excise tax, enter the MSRP for each variant in the Products tab. If you don't set one, StickTax uses your retail price as a fallback.
- Configure excise tax rules — Go to Excise Tax Rules. For each state where you ship, activate the rule, select the correct method, and enter the rates.
- Configure sales tax rules — Go to Sales Tax. For each state where you have nexus, activate the rule and enter the rate.
- Test checkout — Open your storefront in an incognito window, add a product to cart, and checkout with a shipping address in a state you configured. Verify the tax lines appear.
Excise Tax Rules
The Excise Tax Rules tab is the core of StickTax. This is where you tell StickTax how each state taxes cigars.
All 50 states plus DC are pre-populated when you install. Each row has the following fields:
| Field | Description |
|---|---|
| Active | Checkbox. Only active rules calculate tax at checkout. Leave unchecked for states where you don't ship or don't owe excise tax. |
| Method | The excise tax calculation method this state uses. See Tax Methods Explained below. |
| Per Stick | Dollar amount per individual cigar. Used by the per_stick and combo methods. |
| MSRP % | Percentage of MSRP. Enter as a whole number (e.g. 30 for 30%). Used by pct_msrp, pct_msrp_capped, and combo methods. |
| Cap / Stick | Maximum tax per stick in dollars. Used by pct_msrp_capped and combo methods. If the MSRP percentage exceeds this cap, the cap is applied instead. |
| Applies To | Which product formats this rule applies to: All (singles and boxes), Singles Only, or Boxes Only. |
Click Save on each row after making changes. The button turns amber when you have unsaved changes and shows a green checkmark when saved.
Tip: You only need to configure states where you actually ship cigars and owe excise tax. Leaving a state inactive means StickTax returns $0 excise tax for that state — checkout still works normally.
Tax Methods Explained
States tax cigars using four methods. StickTax supports all of them.
Per Stick
A fixed dollar amount per cigar. The simplest method.
| Formula | Example |
|---|---|
| per_stick_rate × stick_count | $0.60/stick × 5 singles = $3.00 tax |
For box variants, StickTax multiplies by the number of cigars in the box. A "Box of 20" at $0.60/stick = $12.00 tax.
Percentage of MSRP
A percentage of the manufacturer's suggested retail price, multiplied by quantity.
| Formula | Example |
|---|---|
| msrp_pct × MSRP × quantity | 21.25% × $12.00 × 1 = $2.55 tax |
Percentage of MSRP with Cap
Same as MSRP percentage, but with a maximum tax per stick. This is the most common method — used by states like Indiana and New York.
| Formula | Example |
|---|---|
| min(msrp_pct × MSRP, cap_per_stick) × stick_count | min(24% × $12.00, $0.72) × 1 = $0.72 tax (capped) |
Without the cap: 24% × $12.00 = $2.88. With the $0.72 cap: tax is $0.72. The cap protects against high tax on premium cigars.
Combo
Both a per-stick rate and a capped MSRP percentage, added together.
| Formula | Example |
|---|---|
| per_stick + pct_msrp_capped | $0.10/stick + min(20% × $12.00, $0.50) = $0.10 + $0.50 = $0.60 tax |
How box variants are handled
For all methods that use a per-stick calculation, StickTax needs to know how many sticks are in the box. This is determined by the profile class assigned to the variant. If a box variant has a profile class of "Box of 20", StickTax multiplies the per-stick tax by 20.
If no profile class is assigned, StickTax defaults to 20 cigars per box.
MSRP fallback
For MSRP-based methods, StickTax uses the MSRP value you set on each variant. If you haven't set an MSRP, it falls back to the BigCommerce retail price. For accurate calculations, we recommend setting MSRP explicitly.
Sales Tax Rules
The Sales Tax tab lets you configure state sales tax rates for states where you have nexus.
| Field | Description |
|---|---|
| Active | Checkbox. Enable for states where you collect sales tax. |
| Rate | Sales tax percentage. Enter as a whole number (e.g. 7 for 7%). |
Sales tax is calculated as: item_price × quantity × rate.
Already using another sales tax provider? If you're using Avalara or TaxJar for sales tax and only need StickTax for excise tax, leave all sales tax rules inactive. StickTax will only calculate excise tax.
Catalog Sync
StickTax syncs your BigCommerce product catalog to know what you sell, what the SKUs are, and which variants are singles vs. boxes.
How to sync
- Go to the Products tab.
- Click Sync Catalog.
- StickTax pulls all products and variants from your BigCommerce store via the API.
What gets synced
- Product name
- Variant SKU
- Variant label (option values like "Toro / Box of 20")
- Retail price
- Active/inactive status
Format detection
StickTax automatically detects whether each variant is a single, box, or bundle by reading the variant label:
- Labels containing "box" or "pack" →
box - Labels containing "bundle" →
bundle - Labels containing "single" or "each" →
single - No clear indicator → defaults to
single
When to re-sync
- After adding new products to your BigCommerce store
- After changing product prices
- After modifying variant labels or SKUs
- Periodically to ensure the catalog is current
Sync does not delete. If you remove a product from BigCommerce, it remains in StickTax's variant list until it naturally falls out of use. It won't affect tax calculations — if a SKU no longer exists in the synced data, StickTax simply can't match it and returns $0 tax for that item.
Profile Classes
Profile classes tell StickTax how many cigars are in each box type. This is essential for accurate per-stick tax calculations on box variants.
Creating a profile class
- Go to the Profile Classes tab.
- Enter a name (e.g. "Box of 20") and the number of cigars per box (e.g. 20).
- Click Add.
Common profile classes
| Name | Cigars Per Box |
|---|---|
| Box of 10 | 10 |
| Box of 20 | 20 |
| Box of 24 | 24 |
| Box of 25 | 25 |
| Bundle of 10 | 10 |
| Bundle of 20 | 20 |
Assigning classes to variants
After creating profile classes, go to the Products tab. Box and bundle variants will show a dropdown in the Class column. Select the appropriate class for each variant.
What if I don't assign a class? StickTax defaults to 20 cigars per box for any box variant without a class assignment. If your boxes contain a different number of cigars, the tax calculation will be incorrect. Always assign classes to box variants.
MSRP Configuration
For states that use MSRP-based excise tax methods (pct_msrp, pct_msrp_capped, combo), StickTax needs to know the MSRP for each product.
Setting MSRP
- Go to the Products tab.
- Find the variant and enter the MSRP value in the MSRP column.
- The value saves automatically when you tab out or click elsewhere.
MSRP fallback behavior
If you don't set an MSRP for a variant, StickTax falls back to the BigCommerce retail price. This is usually close enough for most calculations, but for maximum accuracy we recommend setting MSRP explicitly — especially for products where your retail price differs significantly from MSRP.
MSRP for boxes
Set the MSRP to the full box MSRP, not the per-stick MSRP. StickTax handles the per-stick math internally using the cigars-per-box value from the assigned profile class.
How Checkout Works
Here's what happens behind the scenes on every checkout:
A customer enters their shipping address at checkout. BigCommerce sends a tax estimate request to StickTax with the items in the cart and the shipping state.
StickTax identifies your store by the authentication credentials registered during installation.
StickTax resolves each item's SKU from the cart to find the matching variant in your synced catalog, determining whether it's a single or box and what the MSRP is.
StickTax looks up your excise tax rule and sales tax rule for the shipping state.
For box variants, StickTax looks up the profile class to get the cigars-per-box count.
StickTax calculates excise tax and sales tax for each item and returns the amounts to BigCommerce.
The customer sees the tax lines in their order total. When the order is completed, BigCommerce sends a commit notification and StickTax logs the tax amounts for your records.
This entire process happens in under 2 seconds. BigCommerce calls StickTax multiple times during a single checkout (after address entry, after shipping method selection, etc.) — each call returns updated tax amounts.
Safety first: If anything goes wrong during a tax calculation — a missing SKU, a database error, a timeout — StickTax returns $0 tax rather than blocking the checkout. Your customer's purchase is never interrupted.
Tax History & Export
The Tax History tab shows every tax calculation committed by BigCommerce after order completion.
What's logged
| Field | Description |
|---|---|
| Order | BigCommerce order ID |
| State | Shipping state (2-letter code) |
| Excise Tax | Cigar excise tax amount |
| Sales Tax | State sales tax amount |
| Total Tax | Combined excise + sales tax |
| Date | Order date |

Settings
The Settings tab shows your store information, subscription status, and administrative actions.
Store information
Displays your store name, store hash, plan status, trial end date (if applicable), and installation date.
Manage Subscription
Opens the Stripe customer portal where you can update your payment method, view invoices, or cancel your subscription.
Re-register Tax Connection
If BigCommerce loses the tax provider connection (rare), click this button to re-register StickTax's credentials with your store. This does not affect your rules or data.
Troubleshooting
Tax not showing at checkout
- Check that the state has an active rule. Go to Excise Tax Rules and verify the state is checked as Active with a method and rates configured.
- Check that your catalog is synced. If the product's SKU isn't in StickTax's catalog, it can't match the item and returns $0 tax. Go to Products and re-sync.
- Check the product's tax class in BigCommerce. If a product is set to "Non-taxable" or has
tax_exempt: true, StickTax correctly returns $0. Change the product to "Default Tax Class" in BigCommerce. - Check that prices are exclusive of tax. In BigCommerce → Settings → Tax, ensure your prices are set to "Prices entered are exclusive of tax."
- Enter a complete shipping address. StickTax needs the state code from the shipping address. If the customer hasn't entered their full address yet, BigCommerce may not send the state to StickTax.
- Verify the tax connection is active. Go to BigCommerce → Settings → Tax and confirm StickTax shows as the active tax provider for United States. If not, go to StickTax Settings and click "Re-register Tax Connection."
Tax amount seems wrong
- Check the MSRP value. If you're using an MSRP-based method and haven't set the MSRP, StickTax uses the retail price as a fallback. Verify the MSRP in the Products tab.
- Check the profile class. For box variants, verify the correct profile class is assigned. A box of 24 assigned to a "Box of 20" class will calculate tax on 20 sticks instead of 24.
- Check the method and rates. Open the Excise Tax Rules tab and verify the method, percentage, and cap values match the current state regulations.
- Check the "Applies To" setting. If set to "Singles Only", box variants won't get excise tax (and vice versa). Most states should be set to "All."
Sync not working
- Ensure your store has at least one product with variants.
- Try syncing again — temporary API timeouts can cause a sync to fail.
- If sync continues to fail, contact support@sticktax.com.
"Cancelled" plan but I'm still subscribed
