GST/HST on Inventory: How to Account for Stock as a Small Business

When you purchase inventory for resale, GST/HST applies to those purchases just like any other business expense, and you can claim input tax credits (ITCs) on the tax paid. However, inventory accounting under the GST/HST system involves a few unique rules around how you track stock, handle obsolete items, and report inventory adjustments on your tax return. Understanding these rules helps you avoid overpaying tax and ensures your GST/HST filings stay compliant with the Canada Revenue Agency. When you buy inventory for resale, the GST/HST charged by your supplier is an input tax credit you can claim back (assuming you're registered). This works the same way as other business purchases. Key points: - GST/HST on inventory purchases is recoverable, meaning you claim it back on your GST/HST return - The price you pay for inventory includes the tax, but the tax portion is separate from your actual product cost - You must keep invoices showing the GST/HST amount as proof for CRA audits - If you're not registered for GST/HST, you cannot claim these credits, so the tax becomes part of your product cost This is one reason why reaching the $30,000 registration threshold can actually benefit small businesses with

Frequently Asked Questions

Can I claim GST/HST back on inventory I purchase for resale?

Yes, if you're registered for GST/HST, you can claim input tax credits (ITCs) on the GST/HST paid when you buy inventory. You must keep invoices showing the tax amount as proof. If you're not registered, the GST/HST becomes part of your inventory cost and cannot be recovered.

What happens to GST/HST when inventory is damaged or obsolete?

If you return damaged or obsolete stock to your supplier for credit, you can reverse the input tax credit. If you destroy or donate inventory without returning it, you generally cannot claim an ITC adjustment, though you may claim the loss as a business expense on your income tax return.

Do I need to account for GST/HST separately in my year-end inventory count?

Your inventory valuation for income tax purposes should reflect the cost you paid. If you were registered and claimed ITCs, the inventory value excludes the GST/HST. If you weren't registered, the tax is part of the cost. Either way, the GST/HST treatment doesn't change at year-end; it was handled when you claimed the original ITC.

Is GST/HST charged on imported inventory, and can I claim it back?

Yes, GST/HST is charged on imports at the border. If you're registered for GST/HST in Canada, you can claim the tax paid on imported goods as an input tax credit. Keep all customs and import documentation to support your claim.

Should I use simplified GST/HST accounting if I have a lot of inventory?

Simplified methods like the quick method can reduce paperwork, but they're often better for service-based businesses with lower inventory. High-inventory businesses usually benefit from regular accounting so you can fully claim all ITCs. Ask your accountant which method saves you the most tax.
