Payroll, benefits elections, and worker classification all have deadlines that start the moment someone's first paycheck is due, not whenever you get around to it. Missing these isn't a paperwork inconvenience. It's the kind of thing that turns into a real liability later, including in diligence.
Up to this point, most of your compliance obligations have been about the business itself. A first employee adds a whole new category on top: payroll tax withholding, workers' comp in most states, benefits eligibility timelines, all of it starting on day one whether or not you've set it up yet.
Get payroll running correctly before the first paycheck goes out, not after. Fixing payroll tax withholding retroactively is a lot more painful than setting it up right the first time. And actually confirm worker classification instead of assuming it. Employee versus contractor isn't a preference; it's determined by how the role really works, and misclassifying it is one of the most common, most costly mistakes a small business makes.
Worth knowing too: benefits and retirement-plan obligations often kick in based on headcount or hours thresholds you might not even be tracking yet. Better to know where that line is before you cross it than after.
None of this is complicated when it's set up at the start. It gets expensive specifically when it's discovered later, by an auditor, a state agency, or an investor's diligence team.
