‘I’m a travel content creator. Will I get a tax bill for my free trips and gifts?’

Q I’m in my early 20s and started posting travel-related content on social media about two years ago, hoping to earn some money outside my day job. I’ve built up a good following and regularly get to eat out at restaurants, go on trips and receive gifts, mostly in exchange for posting content about them. I use hashtags such as #ad or #gifted but I recently heard I may also have to pay tax on anything I get for free. I’m now living in fear of getting a letter from the taxman. How do I put my house in order?
