Payroll mistakes that trigger penalties

Payroll penalties are uniquely maddening because they are almost always procedural: the money existed, the intention was honest, and the deadline still passed. Four mistakes account for nearly all of the damage we see.

The four

Late deposits come first. Employment-tax deposit schedules — monthly or semi-weekly — depend on your lookback liability, and depositing on the wrong schedule accrues penalties of up to 15% even when every dollar arrives. Second is worker misclassification: paying employees as contractors avoids payroll tax right up until a state unemployment claim unravels the whole arrangement, retroactively.

Third, missed state registrations. Hire remotely in a new state and you generally owe registration, withholding and unemployment insurance there — the obligation starts with the hire, not with the first notice. Fourth, treating accrued payroll taxes as available cash. Trust-fund taxes are the one liability that pierces the corporate veil: the responsible-person penalty makes owners personally liable, and it survives bankruptcy.

The pattern behind all four is the same: payroll punishes improvisation. A boring, automated, correctly-scheduled system costs less than one penalty letter — which is the entire pitch for ours.
