Shopify tax-inclusive pricing showing wrong VAT-included prices.

Several “tax or price looks wrong” bugs look alike. They do not share one fix. This page is only when tax-inclusive / VAT-included prices on the storefront disagree with how checkout shows tax (included vs exclusive, or tax added twice). When tax overrides fail to Save or apply, open tax override not saving. When the Markets / theme currency converter shows the wrong currency or presentment amount, open currency converter wrong. When Markets Pro / managed markets duties or landed cost do not match, open Markets Pro duties mismatch. When duties / import taxes / DDP are missing, open duties / import taxes missing. When Estimated tax rate, nexus, or product tax codes are wrong but inclusive display is already consistent storefront ↔ checkout, open tax wrong at checkout. This page is only: inclusive / VAT display mismatch storefront vs checkout.

Six ordinary reasons inclusive prices stay wrong: Settings → Taxes “include tax in product prices” off (or on) while the Market expects the opposite; Markets tax include/exclude per country fighting the shop default; theme money.format / cart.show_taxes hard-coding exclusive prices; tax/VAT badge apps rewriting Liquid without cart taxes_included; cart.js showing tax-excluded while checkout is inclusive (or the reverse); shipping tax included on one surface and excluded on the other. Walk them in that order. You already pay for Shopify Tax / Markets. You do not need another VAT SaaS to prove storefront and checkout can agree on inclusive display.

Open the live storefront in the affected Market or VAT region. Screenshot product and cart money (amount, “incl. VAT” / tax badge, any tax line). Proceed to checkout with the same cart; screenshot line items, tax line, and total. In DevTools note cart.js taxes_included / tax_lines, theme cart.show_taxes, and checkout tax display. Confirm you are on the correct Market URL — not a cached primary-market exclusive-price view.

If currency code/symbol is wrong but tax-inclusive mode matches, leave for currency converter wrong. If duties/landed cost differ, leave for Markets Pro duties mismatch or duties / import taxes missing. If inclusive display already matches but the tax rate itself is wrong, leave for tax wrong at checkout.

Align Settings → Taxes and duties “include tax in product prices” (or regional VAT inclusive) with how you sell. Align Settings → Markets → each Market’s tax include vs exclude with that shop default. Fix theme money.format / cart.show_taxes / tax-included badges so they read cart taxes_included instead of hard-coding exclusive (or inclusive) copy. Disable or reconfigure tax/VAT display apps that rewrite Liquid prices without updating cart tax mode. Soft note: override Save failures are tax override not saving; currency presentment is currency converter wrong; duties are Markets Pro duties mismatch / duties missing; nexus/rate with consistent inclusive display is tax wrong at checkout.

Latch’s 72-hour install is ops wiring on the live store — not a conversion-lift guarantee and not a tax-agency retainer.

Checklist: (1) screenshot storefront inclusive/VAT price, (2) screenshot checkout tax display for the same cart, (3) confirm include-tax-in-price + Markets tax include/exclude, (4) fix theme money.format / cart.show_taxes, (5) isolate tax/VAT display apps, (6) recheck shipping-tax include mode, (7) if override Save / currency / duties / nexus rate remain wrong, switch playbooks.

Prove it: after the fix, storefront tax-inclusive amount and labels for a SKU must match checkout tax display for the same Market and cart (no double tax, no surprise exclusive→inclusive jump). If only duties differ, open Markets Pro duties mismatch.

Tax overrides not saving is tax override not saving. Markets / theme currency converter wrong presentment is currency converter wrong. Markets Pro duties / landed cost mismatch is Markets Pro duties mismatch. Duties / import taxes / DDP missing is duties / import taxes missing. Estimated tax rate / nexus / product tax codes wrong with consistent inclusive display is tax wrong at checkout. None of those fix tax-inclusive / VAT prices that disagree between storefront and checkout.

Finish prove storefront vs checkout → include-tax-in-price / Markets tax display → theme money.format isolation first. Only then open the related playbook that matches the remaining symptom.

Stay DIY if you can spend one afternoon on the list above: prove the storefront vs checkout inclusive mismatch, align include-tax-in-price and Markets tax display, fix theme money.format / cart.show_taxes, and stop treating tax override / currency converter / Markets Pro duties / duties missing as the same bug. That is the whole playbook. No agency required. Short answers also live on the merchant FAQ.
