Can I claim Shopify merchant fees?

Yes, but it depends on what you mean by “claim.”

• For taxes: Shopify-related fees are often treated as ordinary business expenses and may be deductible in many places, but the exact treatment depends on your country, business structure, and accounting method. Check your local tax rules or a tax professional before filing.
• For customer refunds: if you refund an order, payment-processing fees may or may not be refunded depending on your payment provider, Shopify plan, and the specific circumstances. Check your provider’s current policy.
• For billing mistakes: if you think Shopify billed you incorrectly, review your invoices in your Shopify admin and contact Shopify Support. Any dispute window or refund policy can change, so verify the current terms in Shopify’s help docs.
