Can you deduct cloud server costs for a website?

Yes—if the website is for a business, cloud server/hosting costs are generally deductible as ordinary and necessary business expenses. This can include recurring charges for cloud servers, storage, bandwidth, CDN, backups, monitoring, and similar hosting infrastructure.

How to treat it in practice:

• Business website: usually deduct as a business expense, often under categories like web hosting, software, internet services, cloud services, or IT expenses.
• Mixed business/personal use: deduct only the business-use portion.
• Personal blog or hobby site: generally not deductible unless it is operated as a genuine profit-seeking business; hobby rules can limit deductions.
• Website development vs. hosting: monthly server costs are usually current expenses, but major website build costs, custom software, or long-term development may need different treatment, including capitalization or amortization.
• Keep records: save invoices, payment receipts, account statements, and notes showing the business purpose.

If this is for a U.S. business, these costs are commonly reported as business expenses on the relevant business tax form, but the exact line/category depends on your entity type and accounting method. If you are outside the U.S., the general principle is similar in many places, but the rules and labels differ.
