White-glove HR support for a city built on relationships.
St. Louis businesses are known for their strong community ties, loyal workforces, and practical approach to growth. Lever1, A Helpside Company, entered the St. Louis market because those values closely align with our customer-first business model.
Our white-glove PEO services give growing companies access to dedicated support across payroll, human resources, employee benefits, workers’ compensation, and compliance, backed by a national HR partner serving clients across Missouri and beyond. Rather than offering a one-size-fits-all platform, we take the time to understand each client’s business, workforce, and long-term goals.
Local Expertise That Goes Beyond the Basics
Part of understanding a market means knowing the details that catch growing businesses off guard. St. Louis is one of the few cities in the country with its own local earnings tax on top of state and federal withholding: a 1% earnings tax, plus a separate 0.5% Payroll Expense Tax paid directly by the employer. City residents owe the earnings tax on all their wages regardless of where they work, while non-residents owe it based on where the work is actually performed, meaning even a single day of hybrid work inside city limits can trigger withholding.
It’s the kind of detail that’s easy to miss and costly to get wrong. Our St. Louis team handles earnings tax registration, withholding, and quarterly filing correctly from day one, including the added complexity of hybrid and multi-location employees, so you can stay focused on running your business.
