E-Verify and Form I-9 are frequently discussed as one process. They are not. Form I-9 is mandatory for every employer in the United States. E-Verify is an additional electronic confirmation that is voluntary for most private employers and mandatory for some — and enrolling in it changes several of your I-9 obligations rather than replacing them.

Understanding which obligations change is the practical core of the topic.

E-Verify Does Not

New hire reporting is the most frequently missed payroll compliance obligation, and the reason is structural: it is not a tax filing, it does not produce a payment, and nothing in the payroll cycle prompts it. It is a report to a child support enforcement registry, and employers who have never received a garnishment often do not know it exists.

The deadline is short, the penalties are modest per instance and cumulative in practice, and the obligation attaches to ...

The year-end bonus run is the payroll cycle most likely to produce a genuine problem, because it combines an unusual amount, an unusual timing, and an employee population paying close attention to their net pay.

The withholding choice is the visible question. The consequences that actually cost money are the deposit threshold, the retroactive overtime, and — for 2026 — the earnings-code coding that determines whether your Form W-2 reports qualified overtime correctly.

"De minimis" is the exclusion employers reach for when they want a benefit to be non-taxable and cannot identify another basis for it. It is also considerably narrower than the way it is used in practice, and it has one absolute rule that resolves most of the questions employers actually have: cash and cash equivalents never qualify.

That single rule disposes of gift cards, which are simultaneously the most common employee appreciation item and the most common fringe ...

Contribution limits are the one part of retirement plan administration payroll cannot delegate. Every limit has to be loaded into the system before the first payroll of the year, monitored during it, and reconciled after — and several of the 2026 rules interact in ways that a single deduction-limit field cannot represent.

The 2026 Limits

Payroll does not administer a 401(k) plan, but payroll determines whether the plan is compliant. Every deferral amount, every compensation figure fed to the recordkeeper, every deposit date, and every loan repayment originates in payroll — and a plan failure traced to a payroll error is corrected under the plan's rules, at the employer's expense, with the fiduciary exposure that comes with it.

This handbook covers what payroll actually owns.

The 2026

When an employee files for bankruptcy, most garnishments must stop — and the obligation to stop is immediate, court-backed, and carries penalties for violation. Payroll is frequently the last function to find out, which is exactly the problem: the automatic stay takes effect on filing, not on notification, and continuing to withhold after it attaches can be a violation even where the employer was genuinely unaware.

This guide covers what stops, what does not, what ...

"Pre-tax" is not a single status. It is shorthand for "reduces some taxes," and which taxes a given deduction reduces varies by deduction type. Treating pre-tax as one binary flag is the most common structural error in payroll configuration, and it is responsible for more year-end reconciliation failures than any other cause.

This guide gives you the matrix, explains the exceptions, and covers the order in which deductions must be applied.
