What expense category is Microsoft Software?
Microsoft 365 is a cloud-based SaaS productivity suite including Office apps (Word, Excel, PowerPoint), Teams, Outlook email, OneDrive storage, and optional Copilot AI, billed per user per month.
Microsoft 365 (formerly Office 365) is Microsoft's flagship subscription-based productivity platform for businesses. It delivers desktop and web versions of Word, Excel, PowerPoint, Outlook, and Teams, along with 1 TB of OneDrive cloud storage per user, SharePoint, and optional AI features via Copilot add-on. Plans are priced per user per month on annual commitments, ranging from $6 (Business Basic) to $22 (Business Premium) for SMBs, and $8–$38+ for enterprise tiers. Because users access the software via subscription and never hold a perpetual license, this is a fully deductible SaaS operating expense. Note: the vendor's assigned category of 'Restaurants' in the source data is incorrect — Microsoft 365 is unambiguously a SaaS product.
How businesses classify Microsoft Software
Tax details
- Microsoft 365 is billed per user per month — reconcile your active user count quarterly to avoid paying for departed employees' licenses.
- Retain the Microsoft 365 admin center invoice each billing cycle; it details per-user costs and plan tiers, which is useful for allocating costs across departments.
- Annual prepaid Microsoft 365 plans can be deducted in full in the year paid if your business uses the cash accounting method.
- Copilot AI add-on fees ($18–$30/user/month) are also deductible SaaS costs — track these as a separate line item if material.
- If Microsoft 365 licenses are provided to employees as a business tool, the cost is fully deductible; if any licenses are used for personal purposes only, that portion should be excluded.
