When it counts
- Recurring subscriptions you use in the business. Design tools, accounting, cloud storage, project tools, AI assistants and similar services.
- Mixed-use tools. Deduct the business share, and keep a note of how you split it.
- One-time software you buy outright, like a license. Off-the-shelf software is depreciated over 36 months, but bought after January 19, 2025 it can usually be deducted in full the year you start using it, through 100% bonus depreciation or Section 179. The $2,500 safe harbor is for physical items, so it is not the route for software.
- It goes on Schedule C, line 27b, other expenses.
When it doesn't
- A subscription you use only personally, like a streaming service.
- The personal share of a tool you use for both.
- Software you bought for personal use before your business started. It is depreciated from the day you first used it for the business, without Section 179 or bonus.
- A subscription you paid for before your business opened. That is a start-up cost. You can deduct up to $5,000 of start-up costs in the first year, and the rest is spread over 180 months.
A worked example
You pay $30 a month for a design tool and use it for client work about 70% of the time.
- Yearly cost: $30.00 times 12 = $360.00
- Business use: 70%
- Your write-off: $252.00
An AI assistant you pay $20 a month for and use only for client work comes to $240.00 for the year, all of it deductible.
What records to keep
- The receipts, invoices or card statements that show each charge.
- What each tool is for. One sentence is enough.
- A note on how you worked out your business use when a tool is shared.
Common questions
Are AI tools deductible?
Yes. A chatbot or AI assistant subscription you use in your business follows the same rules as any software subscription. If you also use it personally, split it.
When do I deduct an annual plan?
WriteOff treats a subscription as an expense in the year you pay it.
How do I deduct a software license I bought outright?
Any one-time software purchase is depreciable property, whatever it costs. Off-the-shelf software is written off over 36 months, unless 100% bonus depreciation or Section 179 lets you deduct it in the first year, which is usually the case for software bought after January 19, 2025.
