Can I write off ChatGPT Plus for blog writing?

Possibly, yes — if you use ChatGPT Plus for a real business purpose, such as writing or brainstorming content for a blog you operate as a profit-seeking activity.

General rule of thumb:

• If your blog is a genuine business, a ChatGPT Plus subscription used for blog writing may be deductible as a business expense.
• If the blog is just a hobby, it is usually not deductible as a business expense.
• If you use it for both business and personal purposes, you generally should deduct only the business-use portion.

Keep receipts and notes showing how you use it for the blog. On a U.S. return, it may be entered as a business expense such as software, office expenses, or subscriptions, depending on how you track and file it.

This is general guidance only. Tax treatment depends on your country, your facts, and how much of the subscription is actually used for the blog, so it’s worth confirming with a tax professional or the relevant tax authority.
