   • Consider holding company structure for regional ops

4. Carry-forward Losses

   • Unlimited carry-forward (subject to shareholding test)
   • Can offset against future profits

Current Rate: 9% (from Jan 1, 2024)

Founder Considerations

1. Voluntary Registration

   • Pros: Claim input tax, appear established
   • Cons: Compliance burden, 2-year lock-in

2. Pricing Strategy

   • B2B: Customers claim back, less price sensitive
   • B2C: 9% impacts competitiveness

3. Export-Heavy Business

   • Zero-rated output, claimable input = GST refunds
   • Consider voluntary registration
