Australian Import Tax Calculator - Duty, GST and Import Costs
Answer: Australian import tax is usually planned as customs duty plus 10% GST on the value of taxable importation, with optional luxury car tax and clearance fees added when they apply.
- Use the confirmed Australian tariff classification, origin treatment, concession status, and customs valuation basis before relying on any duty rate.
- GST is estimated from the value of taxable importation: customs value, duty, and transport and insurance to Australia. Exemptions and GST deferral can change cash timing or liability.
- Luxury car tax is optional here and uses the ATO import formula for planning only. Vehicle approvals, exemptions, fuel-efficiency status, and the final LCT value need official or broker review.
- Import processing charges, port charges, broker fees, storage, inspections, quarantine, permits, and delivery charges are not statutory duty; enter them only when they are relevant to your quote.

How the calculation works
Use this Australian import tax calculator as an exact-match planning variant of the Australian customs duty calculator. Enter values in AUD after converting the invoice, freight, insurance, and local charges using the exchange-rate approach required for your declaration or planning model.
| Step | Formula |
|---|---|
| Customs Duty | customs value x duty rate |
| Value of taxable importation | customs value + Customs Duty + international transport and insurance |
| GST | value of taxable importation x GST rate |
| Optional LCT estimate | max(0, LCT value - threshold) x 10 / 11 x 33% |
| Estimated import taxes and charges | Customs Duty + GST + optional LCT + import processing + port + broker + other fees |
The duty rate still has to come from the correct Australian tariff classification, country of origin, concession status, and any applicable preference or trade-remedy treatment. For broader margin modeling, compare this estimate with the landed cost calculator and custom duty calculator.
If your search is specifically about customs duty rather than the full import-tax total, use the Australian customs duty calculator. For shipment-wide costs beyond tax, use the freight calculator before adding destination and broker charges.
FAQ
How do I calculate Australian import tax?
For planning, multiply the customs value in AUD by the confirmed duty rate, then calculate GST at 10% of the value of taxable importation unless an exemption or special rule applies. Add LCT only for relevant vehicle imports and add local fees only when they are part of your quote.
How is GST calculated on Australian imports?
GST is generally 10% of the value of taxable importation. The planning VOTI used here is customs value plus Customs Duty plus international transport and insurance to Australia.
Is Australian import tax the same as customs duty?
No. Searchers often say import tax, but the estimate normally includes several lines: Customs Duty, GST, optional LCT, and sometimes import processing, port, broker, inspection, quarantine, or storage fees.
What duty rate should I enter?
Use the rate confirmed from the Australian tariff classification, origin, concession status, and any preference or trade-remedy treatment. This page does not classify goods or decide origin.
Does this include luxury car tax?
Yes, as an optional planning field. When enabled, the calculator uses the 2025-26 ATO thresholds and the import LCT formula, but vehicle approval, exemptions, fuel-efficiency status, and final LCT value still need official or broker review.
Does every Australian import pay GST?
No. GST generally applies to taxable importations, but exemptions and special cases exist for some goods and procedures. Confirm non-taxable treatment before quoting landed cost to a customer.
Should I include freight and insurance?
Yes. Freight and insurance to Australia are part of this planning model because they are included in the value of taxable importation used to estimate GST.
Can this replace ABF, ATO, or a customs broker?
No. It is a shipment-planning calculator. ABF, ATO rules, tariff classification, valuation, origin, permits, exemptions, anti-dumping measures, and broker declaration data determine the final liability.
Is this different from the Australian customs duty calculator?
The math is the same, but this page is written for the exact search phrase “Australian import tax calculator.” Use the Australian customs duty calculator when you want the canonical duty-first page.
Comparison
| Option | Best for | What it handles | Main limitation |
|---|---|---|---|
| Australian import tax calculator | Searchers estimating duty, GST, and import charges together | Duty, VOTI, GST, optional LCT, and editable clearance fees | User must supply the correct duty rate and taxable treatment |
| Australian customs duty calculator | Duty-first landed-cost planning | Same calculation with customs-duty framing | Still depends on classification, valuation, origin, and concessions |
| ABF tariff and import guidance | Official customs process and declaration concepts | Classification, valuation, concessions, and import process | Requires product-specific review and may still need broker judgment |
| ATO LCT guidance | Vehicle LCT threshold and formula review | LCT rate, thresholds, and import formula | Does not solve customs classification, approval, or shipping costs |
| Licensed customs broker quote | Pre-entry operational estimate | Documents, classification, duty, GST, fees, and entry handling | Depends on complete shipment documents and broker assumptions |
