Can you deduct Shopify app fees for a store with no sales?

Yes — if the store is genuinely a business, you can usually deduct Shopify app fees even with no sales.

• If the store is live and operating: the app fees are generally ordinary business expenses. You can usually deduct them in the year paid, even if revenue is $0.
• If the store is still pre-launch: the fees are more likely startup costs, which are handled differently and may need to be capitalized until the business is active.
• Watch the hobby-loss issue: if the store keeps losing money and never looks like a real business, the IRS may treat it as a hobby, and deductions can be limited or denied.

Bottom line: no sales alone does not stop the write-off. What matters most is whether the store is active and run with a profit intent. Keep good records and check the current tax rules for your location.
