Hidden payroll fees: 8 charges buried in the fine print

Sticker price almost never matches the bill. These eight categories explain the gap. The annual cost table folds them into one comparable number per provider.

Quick Answer
The big four hidden categories are: W-2 processing ($5 to $25 per form), tax filing add-ons ($10 to $30/mo), off-cycle run fees ($10 to $25 each), and multi-state add-ons ($10 to $20 per state per month). Patriot, ADP, and Paychex bundle the most fees separately. OnPay, Gusto, and Square bundle the most into the sticker price.
The eight

Risk-rated fee categories

Year-end W-2 processing

high risk
$5 to $25 per form

Charged in January for filing W-2s with the SSA. At 25 employees, that is $125 to $625 hitting your bill in one month.

OnPay, Gusto, Square, Homebase, QuickBooks include W-2s.

Tax filing add-on

high risk
$10 to $30/month

Required if you want federal and state taxes filed for you. Patriot Basic, SurePayroll self-service, and Wave self-service charge this separately.

OnPay, Gusto, Square, Homebase, QuickBooks include tax filing.

Setup or implementation fee

medium risk
$0 to $200

Charged once at signup. ADP and Paychex commonly quote this; it is negotiable but rarely waived without asking.

Patriot, Wave, OnPay, Gusto, Square, Homebase do not charge setup fees.

Off-cycle payroll run

medium risk
$10 to $25 per run

Charged when you process a paycheck outside your normal schedule (bonus, commission, terminated employee final pay). ADP and Paychex are the usual culprits.

Most modern providers (Gusto, OnPay, Patriot, Square) include unlimited runs.

Garnishment processing

medium risk
$0 to $25/month per garnishment

Charged per court-ordered wage garnishment in effect. Common at ADP and Paychex; sometimes free at smaller providers.

Patriot, Gusto, OnPay typically include garnishments at no extra cost.

Multi-state add-on

high risk
$10 to $20/state per month

Charged when you have employees in more than one state. Gusto Simple is single-state only; Plus tier ($80 + $12) covers it.

OnPay includes multi-state in the base $40 + $6.

Time tracking add-on

medium risk
$4 to $10 per employee/month

Charged for built-in time tracking. QuickBooks charges $10 per employee for time. Patriot Time and Gusto's add-on are around $6.

Square, Homebase include time tracking. Wave does not offer it.

1099 contractor processing

low risk
$0 to $15/contractor at year-end

Charged in January for filing 1099-NECs. QuickBooks charges $15.99 per e-file. Most providers include 1099s if you are paying contractors through their system.

OnPay, Gusto, Square include 1099-NEC filing.

Schedule C / True annual

True annual cost at 10 employees

This table folds W-2 processing fees into the 12-month subtotal. It changes the ranking compared to a monthly-only view. The cheapest monthly option is rarely the cheapest annual option once year-end fees land.
