GST in Hospitality: What Most Aussie Restaurants Get Wrong

Most Australian restaurant owners assume GST is straightforward: charge 10%, send it to the ATO, move on. But hospitality's messy reality—split invoices from Bidvest, cash takings, staff meals, EFTPOS fees, private functions—creates a minefield of GST traps. Get it wrong, and the ATO will chase you for years. Get it right, and you reclaim thousands in input tax credits you're currently missing.

The five GST mistakes costing you money

1. Claiming input tax credits on non-deductible expenses

This is the number-one mistake Calso sees flagged in venue records. You cannot claim GST back on expenses that aren't directly connected to making taxable supplies. The most common culprits:

• Entertainment and meals for staff or customers — If you're buying a staff meal or a bottle of wine for a VIP guest, that's not deductible. The ATO draws a hard line here.
• Vehicle expenses for personal use — If your ute is registered to the business but you're using it for personal errands, you can only claim the business-use portion.
• Penalty rates and payroll on public holidays — Wages are never GST-deductible (they're not a supply), but some owners mistakenly think they can offset the cost. You can't.

The fix: Audit your last three months of invoices from your suppliers (Bidvest, PFD, Countrywide, local produce). Tag each one as either deductible or non-deductible. Keep a spreadsheet. The ATO loves a paper trail.

2. Getting split invoices wrong

When you buy from a major supplier like Bidvest or Countrywide, your invoice often contains both GST-free items (raw food) and taxable items (cleaning supplies, packaging, equipment hire). If your supplier bundles them into one line item without a breakdown, you're in trouble.

Why it matters: You can only claim input tax on the taxable portion. If you claim GST on a $500 Bidvest invoice that's actually 60% GST-free food and 40% taxable supplies, the ATO will disallow part of your claim.

The fix: Request itemised invoices from your suppliers showing GST treatment per line. Most large suppliers (Bidvest, PFD) will provide this if you ask. If they won't, ask for a credit memo breaking down the split. Document the conversation. This single step can recover $500–$1,500 per quarter for a mid-sized venue.

3. Mishandling takeaway and delivery orders

Takeaway food is GST-free in Australia—that's the rule. But if your invoice to the customer includes delivery, setup, or service charges, those are taxable. Many venues lump everything together and either over-claim GST or under-claim it.

Real scenario: A Melbourne cafe sells a $15 coffee takeaway (GST-free) but charges $2 for delivery via their own driver. The cafe should split the invoice: $15 GST-free, $2 GST-taxable. Most don't.

The fix: Review your POS system settings. If you're using Square, Toast, or similar, configure your menu items correctly: mark food as GST-free, delivery as taxable. For Uber Eats or Menulog orders, check their settlement statements—they often show the GST treatment already, but verify it matches your records.

4. Not tracking cash takings properly

This one's subtle but costly. If you take cash payments, you must still account for GST on them. The ATO assumes all cash is taxable income unless you can prove otherwise (e.g., you sold a GST-free item). Many venues under-report cash GST because they don't reconcile their till.

The trap: If your cash drawer shows $2,000 in daily takings but your bank shows only $1,800 deposited, the ATO will question where the $200 went. If you can't explain it, they'll assume it's unreported income and chase you for GST on the full $2,000.

The fix: Reconcile your till daily. Record cash sales by category (food, drinks, events) in a simple spreadsheet or POS system. At month-end, cross-check your cash total against your bank deposits and GST returns. If there's a gap, investigate immediately—it might be a staff error, a till malfunction, or legitimate refunds. Document everything.

5. Treating private functions and events incorrectly

If you host a private event (a birthday, corporate dinner, or ANZAC Day function), the GST treatment depends on whether the venue is supplying the food and service or just the space.

• Full catering (you supply food, drink, staff): GST applies to the whole invoice.
• Space only (client brings their own caterer): GST applies only to your venue hire, not to the external caterer's supplies.

Many venues charge a flat "function fee" without breaking down the components, which confuses the GST picture.

Real example: A Brisbane bar hosts a Christmas party for 50 people. The venue charges $3,000 flat for the space, bar service, and a cheese board. If the bar doesn't itemise (e.g., "$1,500 venue hire + $1,500 food and beverage"), the ATO might argue the entire $3,000 is subject to GST, or it might challenge whether the food was GST-free. Either way, you lose clarity.

The fix: Always itemise function invoices. Show venue hire, catering, bar service, and any other components separately, with GST treatment clearly stated. This protects you if the ATO audits and gives your client a transparent invoice.

The counter-intuitive tactic: GST on staff meals and comps

Here's something most owners get backwards. If you provide a staff meal or comp a customer's drink, you're making a supply. Technically, you should charge yourself GST on the cost of goods sold, then claim it back. But because the transaction is internal, it's easy to ignore.

Why it matters: If the ATO finds you've been systematically undervaluing staff meals or comps, they can argue you're avoiding GST on a significant portion of your revenue. Over a year, this adds up.

The counter-intuitive move: Some venues create an internal "staff meal" account in their POS system and ring it through at cost (e.g., a $8 staff meal costs you $3 in COGS, so you ring it as a $3 internal sale). This generates a GST liability on the supply price, which you then claim back. It sounds circular, but it creates an audit trail that shows you're treating staff meals consistently and transparently.

Most owners avoid this because it feels like extra work. But if you're audited, that paper trail is gold. Calso's invoice capture and POS integration can automate this tracking, flagging staff meals and comps so you're not manually reconciling them.

Where Calso fits in

GST compliance in hospitality hinges on accurate, itemised invoicing and clear records. Calso's supplier ordering system captures every invoice from Bidvest, PFD, Countrywide, and local suppliers, automatically categorising items by GST treatment. When Calso flags a split invoice or a non-deductible expense, you can fix it in real time rather than discovering it during an ATO audit. The platform also syncs with your POS to reconcile cash takings and event charges, so your GST records stay clean month to month.

Want early access?

If you're managing GST compliance manually—spreadsheets, invoices piling up, uncertainty about what's deductible—Calso is built for you. Join the waitlist at calso.com.au/join for founding-venue access and direct support from the team. Limited spots available in your city, and early venues are already catching thousands in missed credits.

FAQ: GST and hospitality

Q: Do I need to register for GST if my turnover is under $75,000?

No—registration is optional below the $75,000 threshold. But if you're above it (most venues are), registration is mandatory. If you're close to the threshold, registering early can help you claim input tax credits sooner.

Q: Can I claim GST on alcohol purchases?

Yes. Alcohol sold in a venue (bar, restaurant) is taxable, so you claim GST on your purchases. The exception: if you sell takeaway alcohol (e.g., a bottle shop), the same GST rules apply.

Q: What about Melbourne Cup Day or ANZAC Day wages?

Wages are never GST-deductible, even on penalty-rate days. However, you do need to account for GST on any food or supplies you purchase to service that day's event. Don't mix wage costs with supply costs in your GST return.

Q: How often should I reconcile my GST?

Monthly, at minimum. If you're a larger venue, weekly is safer. Reconciliation means comparing your POS takings, bank deposits, supplier invoices, and GST liability. The sooner you spot a discrepancy, the easier it is to fix.
