My wife is working on getting her travel blog off the ground and just asked me about claiming business expenses come tax time. Let's say we go for a week long trip to Spain, she makes some social media posts on her work accounts and creates some blog posts, maybe some shouting out or showcasing a restaurant/experience/service we used while on our trip. While not a traditional "business" trip, she is taking this trip with the intention of making some money back off of it through her content, so is there any portion of the travel expenses that she can claim as business expenses?
