Short answer
Yes. Microsoft 365 is usually tax deductible when you pay for it to run your business (email, document creation, collaboration) and you keep records of the expense.
If you also use Microsoft 365 for personal tasks, you generally deduct only the business-use portion.
When it’s more likely deductible
- You use Microsoft 365 for business email, documents, spreadsheets, or collaboration
- The subscription supports ordinary and necessary business operations (admin, proposals, invoicing, reporting)
- You pay for the plan and keep invoices/receipts and proof of payment
- If mixed-use, you can explain a reasonable allocation (business vs personal)
When it’s not deductible (or risky)
- You use the subscription primarily for personal tasks (schoolwork, household planning, personal email)
- You claim 100% business use but personal use is clearly significant
- You don’t keep invoices/receipts or proof of payment
- The cost is reimbursed and you try to deduct it again
Example
Example: allocating a mixed-use subscription
- Subscription cost: $15/month
- Estimated business use: 80%
- Potential deductible portion: $12/month
Use a reasonable, consistent method and keep a brief note explaining your allocation.
