Salary Requirements for Exempt Employees: State Laws vs. Federal

When it comes to managing employees, one key decision employers must make is whether their workers are classified as exempt or non-exempt. This employee classification determines whether they’re eligible for overtime pay. The difference boils down to salary and job duties, but it’s not always as simple as it sounds — especially when dealing with both federal and state laws. The Fair Labor Standards Act (FLSA) lays the groundwork for salary thresholds across the U.S., but states can impose their own rules. Some states have higher salary requirements than the federal government, and that’s where things get tricky for employers.

7 Consequences for Operating a Business Without a License

Think of a business license as your company’s permission slip to operate. The specific rules vary drastically depending on what your business does and where you do it. A restaurant in Ohio will need different licenses than a software company in California, and even towns within the same state can have their own requirements. It’s enough to make any business owner’s head spin.

Some people love to follow the rules–others live to break them. Many founders and business owners fall at least partially into this second category. After all, innovation requires questioning the status quo. But one area where it’s wisest not to break rules is the law. Employment and tax laws apply to even the earliest stage, most disruptive founders, and not complying comes with penalties and fines. That means when it comes to business compliance, you need to become a certified box-checker.
