|                               |                                                                                                                    |
| ----------------------------- | ------------------------------------------------------------------------------------------------------------------ |
| **What it counts**            | `SUM(totalTax)` across orders in the window. Embedded VAT for inclusive stores or add-on tax for exclusive stores. |
| **VAT / tax treatment**       | This is the metric. UK / EU stores: VAT extracted from gross. US stores: sales tax added on top.                   |
| **Shipping**                  | Tax-on-shipping included if Shopify tax engine charges shipping VAT. UK / EU yes; US varies by state.              |
| **Discounts**                 | Tax computed post-discount in most jurisdictions.                                                                  |
| **Refunds**                   | NOT subtracted. Refund-tax recovery requires separate calculation.                                                 |
| **Cancelled / voided orders** | Included if Shopify indexed them; voided orders typically have £0 tax already.                                     |
| **Currency**                  | Multi-currency arithmetic without FX.                                                                              |
| **Channels / sources**        | All channels. POS contributes till-time tax. B2B with VAT-exempt customers contribute zero.                        |
| **Time window**               | `30D` (default 30D rolling)                                                                                        |
| **Alert trigger**             | None directly; pair with VAT-return cycle for compliance alerts.                                                   |
| **Roles**                     | owner                                                                                                              |

## Calculation

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

## Worked example

A UK skincare DTC brand on Shopify, VAT-registered (20% standard), VAT-inclusive pricing. 30D window 12 Apr 26 to 12 May 26.

| Period component                     | Amount     |
| ------------------------------------ | ---------- |
| Total revenue (gross, VAT-inclusive) | £258,400   |
| Total tax collected (`totalTax`)     | £43,067    |
| **Effective tax rate**               | **16.67%** |

The 16.67% figure is the embedded VAT extracted from the customer-paid total. For a 20% VAT-inclusive price model: £100 gross = £83.33 net + £16.67 VAT.

Six things to notice:

1. **The 16.67% is the canonical UK VAT-inclusive rate.** A drift below 16% would suggest VAT-exempt customer mix shifting (e.g. EU B2B with valid VAT numbers). A drift above suggests reduced-rate items reclassified.
2. **HMRC quarterly forecast.** £43k/30D × 3 = £129k/quarter. Match against your VAT-return forecast; the working draft should align within rounding.
3. **Net VAT liability differs.** This card shows gross collected. Net = collected minus reclaimable input VAT (VAT on supplier purchases). The net is what you actually pay HMRC; this card is one input.
4. **Refund treatment.** A refund unwinds tax: when you refund a £100 VAT-inclusive order, the £16.67 of VAT becomes reclaimable. This card doesn't subtract that; HMRC return does.
5. **Shopify Tax engine accuracy.** Reconcile this card against your accounting record monthly; persistent gaps (>2% of total) indicate misconfiguration.
6. **Multi-currency caveat.** A UK + EU stores would show blended tax-effective-rate that's nonsensical without FX normalisation. Filter to single currency (or single market).

## Sibling cards merchants should reference together

Total Tax is the £-aggregate. Companions:

| Card                                                                         | Why pair it with Total Tax                                     |
| ---------------------------------------------------------------------------- | -------------------------------------------------------------- |
| [Tax Over Time](/nerve-centre/kpi-cards/shopify/tax-collected-over-time)     | The trend version; shows shape and consistency.                |
| [Total Revenue](/nerve-centre/kpi-cards/shopify/total-revenue)               | Aggregate context; tax should be stable percentage of revenue. |
| [Revenue Breakdown](/nerve-centre/kpi-cards/shopify/revenue-breakdown)       | The tax slice of total revenue.                                |
| [Customer Countries](/nerve-centre/kpi-cards/shopify/orders-by-country)      | Tax varies by destination; cross-reference.                    |
| [Customer Segments](/nerve-centre/kpi-cards/shopify/customer-spend-segments) | B2B-exempt customers lower effective rate.                     |
| [Refund Value](/nerve-centre/kpi-cards/shopify/refund-value)                 | Refunds unwind tax; net liability requires this for accuracy.  |

## Reconciling against the vendor's own dashboard

**Where to look in Shopify Admin:**

> **Shopify Admin → Analytics → Reports → "Taxes"** (under *Finance*)

The most direct equivalent. Aggregate by period and rate; should match this card to within sync-lag tolerance.

Other Shopify Admin views:

* **Reports → Sales by billing location**: tax by region, useful for US sales-tax compliance.
* **Settings → Taxes and duties**: tax-engine configuration.
* **Apps**: Avalara, TaxJar, Quaderno produce their own reports.

**Why our number may legitimately differ from Shopify Admin:**

| Reason                     | Direction              | Why                                                                                       |
| -------------------------- | ---------------------- | ----------------------------------------------------------------------------------------- |
| **Tax-engine differences** | Either                 | If using Avalara or TaxJar instead of Shopify Tax, calculation may differ during cutover. |
| **Refund treatment**       | Theirs may be net      | Shopify's report can show net of refunds; we show gross.                                  |
| **Time zone**              | Boundary               | UTC vs store time zone.                                                                   |
| **Multi-currency**         | Aggregate distortion   | We don't FX-normalise.                                                                    |
| **Sync lag**               | Ours lower for "today" | Most-recent 5-15 min may not be in.                                                       |

**Cross-connector reconciliation:**

| Card                                      | Expected relationship                       | What causes legitimate divergence                                                                        |
| ----------------------------------------- | ------------------------------------------- | -------------------------------------------------------------------------------------------------------- |
| Accounting tax balance (Xero, QuickBooks) | Should match within rounding                | Bookkeeping reconciliation; persistent gaps indicate sync error.                                         |
| HMRC / IRS submitted return               | Net liability (collected minus reclaimable) | This card is gross collected; submitted return is net. Both should match the gross side within rounding. |

## Known limitations / merchant FAQs

**Why does my effective rate vary month-to-month?**
Three usual causes:

1. **Customer-mix shift**: B2B-exempt customers reduce effective rate; international shifts change blend.
2. **Product-mix shift**: reduced-rate categories (children's clothing, books in some jurisdictions) reduce effective rate.
3. **Tax-engine misconfiguration**: a new product type added without proper VAT classification.

Stable rates are healthy; large drifts deserve investigation.

**Should I rely on this card for VAT returns?**
No. Treat as a sanity check. For HMRC / IRS submissions, use Shopify's *Taxes* report (which adjusts for refunds and breaks by rate / region) and your accounting record. This card is for monitoring; not for filing.

**Why does Shopify Tax engine matter?**
Different engines compute tax differently. Avalara is the most sophisticated for complex multi-state US or international, but costs subscription fees. Shopify Tax is included; sufficient for most. TaxJar is similar to Avalara, cheaper. Don't underestimate the implementation work in switching engines.

**My multi-currency store, can I split by currency?**
Not directly on this card. Filter the underlying orders by presentment currency in Shopify Admin for per-currency tax breakdown.

**Subscription store: do recurring billings show tax?**
Yes. Each subscription billing creates its own tax line. Subscription brands see steady tax flows.

**Action playbook for using Total Tax:**

1. **Monthly compliance reconciliation**: total here vs accounting closing balance. Match within rounding.
2. **Effective-rate trend monitoring**: stable rate is healthy; sudden shifts deserve investigation.
3. **VAT-registration threshold**: small UK stores approaching £85k threshold need this card to confirm correct configuration once registered.
4. **Tax-engine audit**: spot-check by manually summing order-level totalTax for a single day; should match this card's daily aggregate.
5. **Quarterly VAT-return preparation**: 90D total here = 1 quarter of gross VAT. Subtract refund-tax to estimate net liability.
