Tax accountant for ecommerce in Australia

How ecommerce tax accounting usually works

A practical process starts with a short review: business structure, channels (Shopify, Amazon AU, eBay, WooCommerce), payment gateways (Stripe, PayPal, Afterpay), inventory app, shipping/returns setup and BAS/tax history. We also check ATO registrations and due dates.

From there, the work typically breaks into three stages:

• Immediate triage: stabilise BAS lodgements, fix obvious coding issues, and clean up inventory/COGS mapping.
• Process design: implement clear workflows for settlements, refunds, fees, stock purchasing and landed cost allocation.
• Ongoing review: monthly/quarterly reconciliations, BAS lodgement, year-end tax and advisory on cash flow and margins.

Key Australian tax points for ecommerce

• GST on sales: shipping charged to Australian customers is generally taxable; exports can be GST-free if goods are exported within the required timeframe and documentation is kept.
• Discounts, returns and gift cards: ensure tax treatment is consistent for vouchers, coupon codes and refunds so BAS reports are correct.
• Imports and DGST: claim import GST credits correctly and consider Deferred GST (DGST) to smooth cash flow if eligible.
• Inventory and COGS: include freight, duty and other landed costs in inventory valuation so gross margin is accurate.
• Marketplaces and platforms: understand how Amazon AU, eBay and others handle GST and fees; reconcile settlements, not just bank deposits.
• Payroll and STP: if you run a warehouse or fulfilment team, keep STP, super and leave accruals accurate and timely.
• Registrations: use the Tax Practitioners Board register to verify a tax agent or BAS agent is properly registered.

Typical scope for a tax accountant for ecommerce

• BAS preparation and lodgement based on channel-level reconciliations.
• Income tax planning and year-end returns for companies, trusts and sole traders.
• Import GST credit capture and landed cost workflows.
• Chart-of-accounts and tax code clean-up for carts, gateways and marketplaces.
• System setup or review for A2X, Cin7 Core/DEAR, Unleashed, Cin7, Dext and Xero/QB integrations.
• Cash flow forecasting and stock purchasing guidance aligned to seasonality and ad spend.

If you also need day-to-day coding and bank feeds handled, add bookkeeping for ecommerce or coordinate with your current bookkeeper via a shared workflow.
