Six line items sit outside the headline per employee rate often enough to break a budget built on that rate alone, and most get harder to move after you sign.
Multi-state filing
Operating in more than one state adds a recurring fee at most vendors and nothing at a few. Patriot charges $12 a month for each additional state it files in, and SurePayroll charges $9.99 a month for multi-state payroll with a separate fee where local taxes apply.[1][3] OnPay includes as many states as you need.[2] One remote hire in a new state triggers the fee, so price the states you expect.
Year-end W-2 and 1099 filing
Year-end forms are billed separately at some vendors and included at others. SurePayroll bills W-2 and 1099-NEC forms annually at a $50 base fee plus $5 per form, so a twenty five person company pays $175 each January on top of its subscription, and Square charges $3 per mailed form.[3][4] Patriot includes year-end filings at no additional fee on Full Service, and OnPay includes them too.[1][2]
Time tracking, HR, and compliance add-ons
Time and attendance and HR modules are almost always priced on top of payroll. Patriot sells each at $6 a month plus $2 per employee, SurePayroll's timeclock integrations start at $5 plus $3 per employee, and OnPay's HR add-on is $15 plus $2 per worker with live HR support at $75.[1][3][2] QuickBooks Workforce prices benefits administration at $5 per active employee for employers with twenty or more people.[12] On a twenty five person SurePayroll account, a timeclock integration alone adds about 40 percent to the bill.[3]
Setup and implementation
Implementation is free at the small business end and quoted at the mid-market end. OnPay charges no implementation or integration fees, while independent analysis puts ADP RUN implementation at $500 to $2,000 and notes that a waived fee sometimes reappears on the first invoice as a data migration line.[2][14] Confirm whether migrating this year's payroll history sits inside that number.
Promotional pricing that expires
Most advertised small business prices are promotional, and the renewal rate is frequently double. Patriot's page shows Basic at $8.50 plus $2 and Full Service at $18.50 plus $2.50 under a thirty days free plus 50 percent off for six months offer, against list rates of $17 plus $4 and $37 plus $5.[1] SurePayroll runs alternating free months across the first year, ADP advertises three months free, and QuickBooks runs a frequent 50 percent off first three months offer that independent analysis calls a doubling of cost in month four.[3][9][11] Budget the list rate.
Annual increases
Renewal increases of 3 to 8 percent a year are standard here, and analysis of ADP contracts finds many businesses paying 15 to 25 percent more by year three without adding an employee or feature.[14]
