Retail & Wholesale Tax Deductions: The Complete Guide for Australian Business Owners

Retail and wholesale businesses operate with thin margins, complex inventory management, and significant staff costs. Getting the tax right in this sector can make a real difference to your bottom line — and getting it wrong can mean paying more tax than you owe or triggering an ATO audit.

This guide covers the key deductions available to Australian retail and wholesale businesses, the most common compliance issues in this sector, and how to keep your tax position as clean as possible.

Cost of Goods Sold (COGS): Your Largest Deduction

For most retail and wholesale businesses, COGS is the single largest tax deduction. It represents the cost of the goods you actually sold during the financial year — not what you bought.

The ATO formula is: Opening stock + Purchases during the year – Closing stock = COGS

This means:

• Goods still sitting on shelves at 30 June are not yet deductible — they'll be deducted in the year they're sold
• Accurate stock counts at year-end are essential. The ATO uses trading stock rules to verify consistency.
• Damaged, obsolete, or unsellable stock can be written down to its net realisable value — reducing your taxable income. Document the write-down with photos and a written assessment.

Freight, Import Duties & Customs

For businesses importing goods from overseas:

• Landed cost — the total cost to get goods to your warehouse (purchase price + shipping + insurance + import duties + customs clearance) is included in the cost of goods, not expensed separately
• Import duties (customs duty) — included in COGS
• GST on imported goods — paid at the border but claimable as an input tax credit in your next BAS
• Freight out (delivery to customers) — a separate expense, fully deductible

Staffing Costs

Retail businesses typically have significant staffing costs, all of which are deductible:

• Base wages and casual loadings (under General Retail Industry Award or Shop, Distributive and Allied Employees Award)
• Penalty rates (Saturday, Sunday, public holiday)
• Superannuation at 11.5% (2024–25)
• Workers' compensation insurance premiums
• Payroll tax (state-based, once wages exceed state threshold)
• Staff uniforms (if branded or a mandatory requirement)
• Staff training costs

Store Fit-Out and Equipment

Retail fit-outs — shelving, display cases, signage, lighting, point-of-sale systems, security cameras — are capital assets. They can be:

• Immediately deducted under the instant asset write-off if under the threshold (check current threshold — varies by year and business size)
• Depreciated over their effective life if above the threshold
• Written off immediately if they become damaged or obsolete

For major fit-outs, a Quantity Surveyor's depreciation report identifies which elements qualify for faster write-offs — this can significantly improve your Year 1 cash flow position.

Occupancy and Lease Costs

• Rent payments (including GST — claim the GST back in your BAS)
• Outgoings payable under the lease (council rates, water, maintenance contributions)
• Lease incentive repayments (if you received a rent-free period, you may need to apportion the future repayment)
• Commercial lease legal fees (capital cost — part of setting up the lease, amortised over term)
• Cleaning and waste removal
• Utilities — electricity, gas, water

Marketing and Advertising

• Social media advertising (Meta, TikTok, Google Shopping)
• Loyalty program costs (points redemption, program setup)
• Catalogue design and printing
• Website and eCommerce platform costs
• Seasonal sales promotion costs
• Photography and video content for product listings
• Influencer partnerships (if commercially structured)

Technology and Software

• POS system subscription (Square, Lightspeed, Shopify POS)
• Inventory management software
• Accounting software (Xero, MYOB)
• eCommerce platform fees
• Cybersecurity software and data storage

Shrinkage, Theft & Write-Offs

Retail shrinkage (inventory lost to theft, breakage, or administrative errors) is a deductible business expense. However, it must be:

• Documented — physical stock counts, CCTV evidence, police reports where applicable
• Written off against stock on hand — not claimed as a separate expense
• Consistent with industry benchmarks to avoid ATO scrutiny

GST in Retail and Wholesale

Most retail and wholesale products attract GST at 10%. Exceptions:

• Basic food items — fresh produce, bread, milk, unprocessed foods are GST-free
• Children's clothing — clothing and footwear for children under a certain age can be GST-free
• Medical supplies — if you wholesale medical devices or supplies, specific GST-free classifications may apply
• Exports — goods exported are GST-free regardless of the product type

Getting product GST classifications right in your POS from day one avoids BAS errors and ATO audit risk.

Common Tax Mistakes for Retail Businesses

• Inaccurate year-end stock counts leading to incorrect COGS calculation
• Failing to write down damaged or obsolete stock
• Incorrect GST classification of food or exempt products
• Claiming personal purchases through the business
• Underpaying retail Award wages and penalty rates
• Missing superannuation on casual staff
