Running paid ads on Facebook, Instagram, LinkedIn, or other social platforms is a deductible business expense when the ads promote your business. The money you spend on social media advertising is treated the same as any other advertising cost and is fully deductible in the year you pay it. This includes boosted posts, sponsored content, retargeting campaigns, and any ad management fees you pay to someone who runs the campaigns for you. Ads promoting personal content or a hobby that has not risen to the level of a business do not qualify. Keep your ad account invoices or screenshots of billing statements as documentation.
