Can you deduct app store developer fees?

Generally, yes: app store developer fees are often deductible if your app activity is a real business and the expense is ordinary and necessary for that business.

Common examples include:

• Annual developer account fees: often deductible as a business expense.
• App store commissions or platform fees: often deductible as a business expense, or in some cases booked as cost of sales depending on your accounting method.

Important caveats:

• If your activity is treated as a hobby rather than a business, deduction rules are much more limited.
• Tax treatment can vary by country, by the platform, and by how you report your books and income.
• Keep records of fees, payouts, invoices, and any tax forms you receive.
• If the app store or payment platform reports gross receipts to tax authorities, make sure your income reporting matches the forms you receive to avoid mismatches.

Because exact treatment can change and depends on your facts, it’s best to verify the details with a CPA or tax professional for your situation.
