# Total Tax Collected, BigCommerce

> Total Tax Collected for BigCommerce stores. Tracked live in Vortex IQ Nerve Centre. How to read it, why it matters, and how to act on it.

**Metrics type:** [Supporting Metrics](/nerve-centre/overview#metrics-types-explained)  •  **Category:** [Ecommerce Platform](/nerve-centre/connectors#connectors-by-type)

## At a glance

> Total tax collected from customers in the period. Sums VAT (UK / EU), state and local sales tax (US), GST (Australia / NZ / Canada), and any other tax types configured. **BigCommerce supports three distinct tax engines**: native BC tax (manual rate tables), Avalara AvaTax (real-time API rates), and TaxJar (similar). Each produces slightly different numbers, and reconciliation between this card and the tax-engine dashboard is essential for stores with multi-jurisdiction nexus. The aggregate dollar version of [BC Tax Over Time](/nerve-centre/kpi-cards/bigcommerce/tax-collected-over-time).

| **What it counts**        | `SUM(total_tax)` over the period. The customer-paid tax across all order line items.                                                                                                                                                                                                                                                                                                               |
| **VAT / tax treatment**   | This card *is* the tax view.                                                                                                                                                                                                                                                                                                                                                                       |
| **Shipping**              | Tax on shipping is included if the merchant configured shipping as taxable (typical for UK / EU; varies by US state).                                                                                                                                                                                                                                                                              |
| **Discounts**             | Tax is calculated on the post-discount subtotal in BC's default mode.                                                                                                                                                                                                                                                                                                                              |
| **Refunds**               | Tax on refunded orders included by default (gross). For net tax (refund-adjusted), use the BC tax export.                                                                                                                                                                                                                                                                                          |
| **Cancelled orders**      | Excluded.                                                                                                                                                                                                                                                                                                                                                                                          |
| **`Incomplete` orders**   | Excluded.                                                                                                                                                                                                                                                                                                                                                                                          |
| **Currency**              | Multi-currency without FX.                                                                                                                                                                                                                                                                                                                                                                         |
| **Channels / sources**    | All channels aggregate, with a major caveat: **marketplace-collected tax** (Amazon, eBay, Walmart in marketplace-facilitator states) is NOT collected by the merchant; BC `total_tax` on those orders shows \$0 even though tax was collected by the marketplace and remitted directly. **This is a significant reconciliation gap on Amazon-heavy stores**; pair with the marketplace tax report. |
| **Tax engine caveat**     | Stores using Avalara or TaxJar see tax calculated by the engine and recorded in BC's `total_tax`. If the engine fails (timeout, expired creds), BC falls back to native tax tables, which usually compute differently. **Sudden movements in this card commonly signal engine failover** rather than sales change.                                                                                 |
| **B2B Edition behaviour** | B2B customer groups are typically tax-exempt (resale certificates on file). Tax on B2B can be near-zero even on substantial revenue. Filter to retail customer groups for end-customer tax view.                                                                                                                                                                                                   |
| **Time window**           | `30D` (rolling 30 days).                                                                                                                                                                                                                                                                                                                                                                           |
| **Alert trigger**         | None directly; an anomaly fires if effective tax rate (tax / revenue) shifts more than 2pp.                                                                                                                                                                                                                                                                                                        |
| **Roles**                 | owner                                                                                                                                                                                                                                                                                                                                                                                              |

## Calculation

```
SUM(totalTax)
  WHERE date BETWEEN [period_start, period_end]
```

## Worked example

A US apparel brand on BigCommerce, 30-day window. Multi-state nexus: registered in CA, NY, TX, FL, IL, WA, MA. Avalara AvaTax integration.

| Channel                | Revenue (\$)  | Tax collected (\$) | Effective tax rate | Notes                                                  |
| ---------------------- | ------------- | ------------------ | ------------------ | ------------------------------------------------------ |
| Web (`channel_id = 1`) | \$172,000     | \$11,200           | 6.5%               | Avalara-managed across nexus states                    |
| Amazon UK              | \$42,400      | \$0                | 0.0%               | **Marketplace facilitator (Amazon collects + remits)** |
| B2B Edition            | \$6,800       | \$80               | 1.2%               | Most B2B customers tax-exempt                          |
| POS (single store, NY) | \$1,800       | \$144              | 8.0%               | NY sales tax on apparel                                |
| **Blended**            | **\$223,000** | **\$11,424**       | **5.1%**           |                                                        |

What's interesting:

1. **Amazon shows $0 tax in BC even though Amazon collected tax.** Amazon is a marketplace facilitator in 47 states; they collect and remit on the merchant's behalf. **This $0 is correct from BC's perspective but understates total tax collected** by the merchant + Amazon together. For total tax reporting, sum Amazon's tax report + BC's tax. This is a common reconciliation gap.
2. **Effective rate of 6.5% on web** reflects multi-state nexus mix. CA (7.25-10.5%), NY (4-9%), TX (6.25-8.25%) all weighted by sales volume. Single-state stores have flatter rates; multi-state stores have weighted-average rates.
3. **B2B at 1.2%** because most B2B customers have resale certificates on file (tax-exempt). The 1.2% comes from B2B sales to non-exempt buyers.
4. **POS at 8.0%** because NY apparel-tax exemption (apparel under \$110 is tax-exempt in NY) only applies to lower-priced items; higher-priced apparel pulls the rate above the standard apparel-rate.
5. **Blended 5.1% is meaningful for trend monitoring** but actionable analysis happens at channel level.

Action playbook this card surfaces:

1. **Track effective tax rate as a stability signal.** If the rate moves >2pp suddenly, investigate (engine issue, customer-mix shift, jurisdiction rate change).
2. **Reconcile against Avalara / TaxJar dashboard monthly.** The engine knows what tax should have been collected; BC knows what was collected. Gaps signal engine issues.
3. **Treat marketplace-collected tax separately.** Amazon, eBay, Walmart tax reports are authoritative for those channels.
4. **Audit B2B exempt certificates annually.** Expired or missing certificates create unintended tax-exempt orders that fail audit.
5. **Pair with [BC Tax Over Time](/nerve-centre/kpi-cards/bigcommerce/tax-collected-over-time)** for the time-series view.
6. **Use the Avalara filings export** for actual tax filings, not this card; this card is for trend monitoring only.

## Reconciling against the vendor's own dashboard

**Where to look in BigCommerce's own dashboard:**

The native view is **BC Control Panel → Reports → Tax Reports** (all tiers) or **Analytics → Insights → Sales** with the tax column toggled on (Plus and Enterprise). The BC Tax Report is the authoritative figure for what BC recorded.

For tax-engine integrations, the engine dashboard is the source of truth:

* **Avalara AvaTax:** Avalara console → Reports → Tax Liability Report.
* **TaxJar:** TaxJar dashboard → Reports → Tax Liability.

For marketplace-collected tax: Channel Manager → (channel) → Tax Reports. Amazon Seller Central also publishes tax reports separately.

**Why our number may legitimately differ from the vendor's:**

| Reason                         | Direction         | Why                                                                                                               |
| ------------------------------ | ----------------- | ----------------------------------------------------------------------------------------------------------------- |
| **Marketplace-collected tax**  | Ours lower        | Amazon, eBay, Walmart often collect and remit; BC `total_tax` shows \$0. The marketplace dashboard has the truth. |
| **Tax engine failover**        | Either            | If Avalara / TaxJar timed out and BC fell back to native, recorded tax differs.                                   |
| **Time zone**                  | Boundary days off | UTC vs store time zone.                                                                                           |

## Known limitations / merchant FAQs

\*\*Why is my Amazon tax showing $0?**
Amazon is a marketplace facilitator in 47 US states; they collect sales tax on the customer's behalf and remit it directly to states. The merchant didn't collect the tax, so BC records $0. **For total tax including marketplace-collected, sum BC's `total_tax` + Amazon Seller Central tax report.**

**My effective tax rate jumped from 5% to 8% in a week, what changed?**
Three usual causes: (1) a new state nexus registration adding sales-tax collection in a new state, (2) a customer-base shift toward higher-tax-rate jurisdictions (more CA / WA orders, fewer NH / OR orders), (3) a tax-engine reconfiguration. Audit recent Settings → Tax changes and check Avalara / TaxJar for nexus updates.

**Should I trust this number for tax filings?**
Treat the tax engine (Avalara / TaxJar) as authoritative for filings; this card is for trend monitoring. The engine knows what should have been collected per jurisdiction; this card knows what was actually recorded.

**Why does my B2B portal show near-zero tax?**
B2B customer groups with resale certificates are tax-exempt. Structurally normal.

**My tax dropped after I integrated Avalara, why?**
Possible reasons: (1) Avalara is more accurate than your previous manual rates (you were over-collecting, now correctly collecting less), (2) Avalara isn't finding nexus for some states you thought you had nexus in, (3) Avalara is treating some categories as tax-exempt that your manual tables didn't. Verify Avalara nexus configuration matches your registrations.

**Can I see tax by state?**
Yes via Ask Viq: "tax collected by state for last 30 days". Useful for nexus monitoring.

**Why does shipping tax appear in this card sometimes and not others?**
Whether shipping is taxable varies by state and by configuration. UK / EU stores typically tax shipping; US states are split. Configuration changes mid-period cause movements. Audit Settings → Tax → Shipping Tax setting.

**Does this include UK VAT?**
Yes if you collect VAT (UK / EU stores). The BC `total_tax` field aggregates all tax types regardless of jurisdiction.

**My multi-currency store shows tax for each currency, can I get a single number?**
Use Ask Viq with currency conversion: "total tax converted to USD for last 30 days" applies day-rate FX for unified view.

**Should I worry about chargebacks affecting this?**
Chargebacks themselves don't directly affect this card; they affect refund tax adjustments. If a chargeback was processed via BC's refund flow, the tax adjustment posts; if processed gateway-side, BC may not know.

**Why is my POS tax higher than my web tax for the same product?**
Possibly: (1) POS uses store-location tax rate (NY 8%), web uses customer-location tax rate (varies by destination), (2) POS doesn't apply customer-group exemptions automatically, (3) different shipping-tax handling. Audit a sample of POS vs web orders for the same product.

**Can I export this for my accountant?**
Yes. BC's native Tax Report is the cleanest source; this card is for monitoring. Settings → Data Solutions → Export → Orders with tax columns provides line-item detail.

**Does this card include tax on refunded orders?**
Yes by default (gross). For net (refund-adjusted) tax, use Ask Viq: "show net tax for last 30 days". The difference is your refund tax liability adjustment.

**Why does my Avalara console show different tax than BC?**
Avalara may include tax that BC didn't record (engine timeout, manual override). Or Avalara may exclude tax that BC recorded (fallback to native rates). Reconcile per-state monthly.

**My subscription store shows much higher tax % than expected, why?**
Possible reason: subscription orders auto-renew at the customer's home rate, and your subscription customer base is concentrated in high-tax states. Check the geographic distribution of subscription customers via [BC Customer Countries](/nerve-centre/kpi-cards/bigcommerce/orders-by-country) or [BC Top Cities](/nerve-centre/kpi-cards/bigcommerce/top-cities-by-orders).
