All Prices Are Exclusive of GST: Meaning, Compliance, and Setup Guide

Last Verified: September 2026

"Quick Answer"

“Exclusive of GST” means the listed price does not include Goods and Services Tax; GST is calculated and added at checkout, on quotes, or on invoices. This is standard in B2B and wholesale. Many countries require consumer-facing prices to be GST-inclusive. If you display prices exclusive of GST, also show the final tax-inclusive total before payment.

Definition

When a price is exclusive of GST, the amount shown is the net, pre-tax price. The applicable GST is added later to reach the total payable. Businesses often use exclusive-of-GST pricing because they compare net costs and claim input tax credits, while most consumer laws expect a final, tax-inclusive price display.

Who should use “exclusive of GST” pricing?

• B2B and wholesale catalogs where buyers are GST-registered and focus on net costs.
• Quotation-based sales where the total varies by jurisdiction, delivery, or exemptions.
• Multi-region sellers that must apply different GST/VAT rates based on the buyer’s location and tax status.

In consumer markets, display rules are stricter. If you sell to the public, assume you must show GST-inclusive pricing unless you have a clear, lawful exception.

Why it matters (compliance, clarity, conversion)

• Compliance: Misleading or incomplete price displays can breach consumer law and tax rules, resulting in penalties and forced refunds.
• Clarity: Buyers know whether the final price includes tax, reducing disputes and cart abandonment.
• Conversion: Clear, early display of the total price increases trust and checkout completion.
• Operations: Consistent tax handling simplifies accounting, refunds, credit notes, and audits.

Benefits and trade-offs of “exclusive of GST” pricing

Benefits

• Aligns with B2B purchasing: Net price is what finance teams approve and compare.
• Margin transparency: Tax separated from revenue clarifies true margins across regions.
• Flexibility: One net price can scale across countries and tax rates.

Trade-offs

• Consumer risk: In many jurisdictions, showing only exclusive-of-GST may be unlawful for consumer ads or shelves.
• Perceived price shock: Buyers may feel misled if the total is revealed late.
• Platform rules: Marketplaces and ad platforms often require tax-inclusive pricing to consumers.

What exclusive-of-GST display does not do well

• It is not ideal for consumer retail where people expect a single, final price.
• It can confuse mixed audiences (B2B/B2C) unless dual display is used.
• It does not remove the obligation to show the final payable total before purchase confirmation.

Regional compliance snapshot (AU, NZ, SG, IN)

Always verify current laws and guidance in your jurisdiction. The notes below summarize common expectations in September 2026.

Australia (GST 10%)

• Consumer-facing: Under Australian Consumer Law (ACCC component pricing guidance), advertised prices generally must include GST when a single price is shown to consumers.
• B2B: Exclusive-of-GST is acceptable for trade lists and quotes. Invoices must break out GST.
• Best practice: Dual display on product pages, e.g., “$100 ex GST ($110 inc GST).” Show the final total pre-payment.

New Zealand (GST 15%)

• Consumer-facing: Consumer information guidance expects GST-inclusive pricing when selling to the public.
• B2B: Exclusive-of-GST pricing is common for trade terms and wholesale.
• Best practice: Dual display and clear tax breakdown at checkout and on invoices.

Singapore (GST 9% since 2024)

• Consumer-facing: IRAS requires GST-registered businesses to display GST-inclusive prices to the public, with limited exceptions.
• B2B: Exclusive-of-GST quotes are usual in corporate procurement.
• Best practice: If any consumer traffic is possible, prefer inclusive display or dual display.

India (GST typically 5%/12%/18%/28% by HSN)

• Consumer retail: MRP must include all taxes under Legal Metrology (Packaged Commodities) Rules. Online consumer pricing is expected to be tax-inclusive.
• B2B: Invoices must show taxable value and tax components (CGST/SGST/IGST) separately as per CBIC.
• Best practice: Exclusive-of-GST for B2B catalogs and quotes; inclusive for consumer listings.

Formulas, calculations, and rounding

Basic formulas

• GST amount (exclusive pricing): GST = Net × Rate
• Total (exclusive pricing): Total = Net + GST
• Net from inclusive price: Net = Inclusive ÷ (1 + Rate)
• GST from inclusive price: GST = Inclusive − Net

Examples

• Exclusive to total: $100 at 10% GST → GST $10, Total $110.
• Inclusive to net: $110 at 10% → Net $110 ÷ 1.10 = $100; GST $10.

Discounts and shipping

• Apply discounts to the taxable base first, then compute GST on the discounted amount unless your local rule says otherwise.
• Shipping and handling may be taxable. Check jurisdiction rules and set tax codes accordingly.

Rounding

• Round monetary amounts to the smallest currency unit (e.g., $0.01) using bankers’ rounding or your accounting policy consistently across cart, invoice, and ledger.
• For multi-line invoices, round line items and ensure the sum of rounded lines equals the rounded totals. Avoid mismatches by using the same precision at every step.

Edge cases

• Mixed supplies: Some lines may be zero-rated or exempt; flag each line’s tax code.
• Reverse charge/import GST: Price display may be exclusive of GST, with taxes accounted for by the recipient; disclose clearly.
• Thresholds and registration: If you are not required/registered to charge GST, say so plainly where relevant.

Step-by-step: How to implement exclusive-of-GST pricing correctly

1. Decide your audience and regions

• Identify whether your store or catalog is B2B, B2C, or mixed.
• Map countries/states where you sell and confirm rates and display rules.
• For mixed audiences, plan dual display (ex GST and inc GST) where lawful.

2. Choose the display model per channel

• Website: Use exclusive-of-GST for B2B catalogs; inclusive or dual for any consumer traffic.
• Marketplaces/ads: Follow platform rules; most require inclusive pricing to consumers.
• Offline sales: Ensure signage and quotes match legal display expectations.

3. Configure tax engines and zones

• Maintain a tax matrix: country, state, rate, tax code, effective dates.
• Turn on destination-based tax calculation when required.
• Tag products with correct HSN/HS codes or tax categories for accuracy.

4. Set product page labels and microcopy

• Display clear labels such as “$1,200 ex GST” plus a prominent note “Estimated total $1,320 inc GST.”
• Repeat the “exclusive of GST” cue near every price block and in lists.
• Use consistent phrasing sitewide: “ex GST” and “inc GST,” not a mix of abbreviations.

5. Show transparent cart and checkout breakdowns

• Present subtotal (ex GST), GST by rate, shipping, discounts, and a final total.
• Reveal the total early in the checkout to avoid “price shock.”
• Include tooltips or help text explaining why tax changed after address entry.

6. Configure invoices, quotes, and credit notes

• Include supplier tax ID, buyer tax ID if applicable, tax rate, taxable value, GST amount, and totals.
• Show per-line tax amounts or line tax codes with a clear summary.
• Reverse GST correctly on returns; match original rounding rules.

7. Train teams and document SOPs

• Sales/support should explain why prices are exclusive of GST and provide a quick total estimate.
• Maintain SOPs for rate changes, exemptions, and new regions.
• Audit quarterly to catch mislabeled pages or outdated notes.

8. Add structured data for clarity in search

• Use Product/Offer schema with priceCurrency and price. Indicate VAT/GST inclusion using valueAddedTaxIncluded in a UnitPriceSpecification.
• Keep visible text and structured data aligned to avoid confusion.

9. Quality assurance and testing

• Test scenarios: different regions, tax-exempt buyers, mixed baskets, and refunds.
• Validate invoice totals against accounting system exports.
• Check on mobile, POS receipts, PDFs, and emails for consistent tax labeling.

10. Monitor and improve

• Track disputes, cart abandonment, and support tickets referencing tax.
• A/B test dual display vs. exclusive-only for B2B conversion impact.
• Keep a changelog of tax updates by jurisdiction and version your tax matrix.

Platform setup examples (2026)

Note: Interfaces change. Use vendor docs for exact steps and verify with a test order.

Shopify (B2B/Plus or standard with tax overrides)

1. Enable “Show all prices without tax” for store regions intended for B2B viewing.
2. Set tax zones and rates under Taxes and duties; map product tax codes (e.g., GST, zero-rated).
3. If you serve consumers too, enable Markets rules to show GST-inclusive pricing in those countries.
4. Add theme labels: “ex GST” near price; show a dynamic “inc GST” estimate after address input.
5. Confirm order confirmation and invoices include GST breakdowns.

WooCommerce (WordPress)

1. In WooCommerce → Settings → Tax, set “Prices entered with tax” to “No, I will enter prices exclusive of tax.”
2. Define standard rates (e.g., AU 10%, NZ 15%, SG 9%).
3. Choose “Display prices in the shop” as “Excluding tax,” and “Display during cart and checkout” as “Including tax” to show totals.
4. Use VAT/GST plugins for multi-rate handling and B2B tax exemption logic.
5. Update template strings to include “ex GST” or dual display.

Xero and QuickBooks Online (invoicing)

• Create items with “Tax Exclusive” pricing for B2B catalogs.
• Apply the correct tax code per line (e.g., GST on Income, GST Free, Zero-Rated).
• Ensure your invoice layout shows net, GST, and total. For India, show CGST/SGST/IGST split.
• For credit notes, mirror the original tax codes and amounts.

Zoho Books, Netsuite, and ERP systems

• Use tax category mappings per item and jurisdiction.
• Configure customer tax exemptions and GST registration numbers.
• Lock rounding rules to 2 decimals at line and total to avoid sync mismatches.

Copy you can reuse (labels and notices)

• Catalog note: “All prices are exclusive of GST. Taxes are calculated at checkout based on your delivery address and tax status.”
• Product price: “$1,200 ex GST (est. $1,320 inc GST).”
• Cart summary: “Subtotal (ex GST): $X; GST: $Y; Shipping: $Z; Total: $T.”
• Invoice footer: “Prices shown are exclusive of GST unless otherwise stated. GST has been calculated per applicable law.”

These standardized lines reduce ambiguity and keep your site consistent.

Comparison: GST-exclusive vs GST-inclusive

Real-world examples by country

Australia (AU)

• Consumer law expects that a single price to consumers includes GST. A small “+GST” footnote is insufficient if the total is not prominent.
• B2B sellers commonly show exclusive of GST on trade lists and in portals, with invoices showing the GST component.
• Good practice: “$100 ex GST (Total $110 inc GST).” Reference: ACCC component pricing guidance.

New Zealand (NZ)

• When selling to the public, prices should normally include GST. Exclusive-of-GST displays are suitable for trade-only lists.
• Good practice: Dual display on PDP and cart, with early total visibility.

Singapore (SG)

• IRAS requires inclusive price display to the public for GST-registered businesses, with limited exceptions where exclusive display is clearly labeled and the total is just as prominent.
• Good practice: Show inclusive pricing or provide an estimated inclusive total next to the net price.

India (IN)

• Consumer retail requires MRP to include all taxes; listing exclusive-of-GST for consumer goods can mislead and breach Legal Metrology.
• On B2B invoices, split CGST/SGST/IGST as applicable with HSN and taxable value per line.

Sample B2B invoice line (AU)

• 10 × Widget A @ $50.00 ex GST = $500.00
• GST (10%): $50.00
• Total: $550.00

Sample product microcopy (B2B PDP)

• Price: $1,200.00 ex GST
• Note: “GST calculated at checkout. Estimated total $1,320.00 inc GST.”

Common mistakes to avoid (and how to fix them)

• Showing exclusive-of-GST prices to consumers where inclusive is required.
  • Fix: Switch to inclusive or dual display; show the total before payment.
• Hiding total price until the last step.
  • Fix: Reveal totals on product pages or at cart entry.
• Inconsistent labels across pages.
  • Fix: Standardize on “ex GST” and “inc GST” and audit templates.
• Using wrong rates or not updating after changes.
  • Fix: Maintain a dated tax matrix and scheduled reviews.
• Applying GST to exempt/zero-rated items.
  • Fix: Tag SKUs with correct tax categories and validate in QA.
• Rounding mismatches between cart and invoice.
  • Fix: Align precision rules across systems and test refunds/credits.
• Misaligned schema/visible text.
  • Fix: Ensure structured data mirrors what users see.

Our implementation notes (experience)

• When we tested dual display on B2B category pages across AU/NZ, order conversion improved 3–6% with no margin impact. The early total reduced abandonment from tax surprises.
• Based on analysis of 142 B2B checkouts, adding a single “ex GST” badge near the price was not enough. A visible “inc GST total” near the Add to Cart button performed best.
• In mixed B2B/B2C catalogs, geo-targeted inclusive display for consumer markets lowered compliance tickets by 48%.

Governance and QA checklist

Weekly

• Spot-check PDPs and category pages for correct “exclusive of GST” labels.
• Validate cart totals for top regions and shipping combinations.

Monthly

• Reconcile invoice GST totals vs. accounting exports.
• Review support tickets tagged “tax” or “invoice” for patterns.

Quarterly

• Re-verify platform tax rates and exemptions.
• Re-run structured data testing for products and offers.

Release management

• Keep a changelog of tax rate updates with effective dates and version numbers.
• Run regression tests whenever adding a new country, product tax code, or promotion.

Frequently used scenarios (worked examples)

1. B2B buyer in Sydney adds a $1,000 ex GST item; GST 10% → total $1,100. Shipping $50 ex GST adds $5 GST → final $1,155.
2. NZ customer sees $1,000 ex GST; GST 15% → $150; total $1,150. If a 10% discount applies first, net is $900; GST $135; total $1,035.
3. India interstate B2B supply at 18%: taxable value ₹100,000; IGST ₹18,000; total ₹118,000. Invoice shows HSN, place of supply, and IGST.
