Here's the problem: social media advice (what we jokingly call "TikTok Tax"), friendly "tips" from well-meaning people, and guesswork all lead to costly mistakes. Either you leave money on the table, or you risk IRS trouble.
Here's the truth: the IRS doesn't care what your cousin or a tax influencer told you. It cares about three tests.
You need an actual business with the primary goal of making a profit, not just a hobby that occasionally makes money.
You need to actually be up and running, not just planning to be. Expenses you rack up before your business is genuinely open for business get treated differently than the ones you incur once you're operating, so timing matters as much as the expense itself.
Ordinary means common in your industry. Necessary means helpful to running your business.
Yes, that means client lunches may qualify with proper documentation. No, it doesn't mean you can write off haircuts or gym memberships because they "help your brand."
The Cost of Confusion
If you don't know the rules, you may overpay tax every year. Or worse, you may underpay and invite an audit.
Neither one helps you build a profitable, sustainable business.
