OnPay

OnPay has a single, transparent plan: a flat monthly base fee plus a per-employee fee of $6/emp/mo, with every feature included and no tiers to navigate. Because there is only one plan, you get full-service tax filing, benefits, and HR tools at the same price regardless of size. The comparison table on this page shows the current base and per-employee fees, and the calculator above estimates your monthly cost on your headcount.

Yes. OnPay is full-service, calculating, filing, and paying your federal, state, and local payroll taxes, generating and filing W-2s and 1099s, and handling new-hire reporting. Everything is included in the single plan rather than gated behind a higher tier, which is part of why OnPay is a strong value pick for small businesses.

Yes. OnPay is well known for serving nonprofits and agricultural employers, handling the specific payroll needs of those sectors (such as clergy payroll and farm worker rules) within its single plan. Combined with its flat, all-inclusive pricing, this makes it a practical choice for organizations that want full-service payroll without paying for features they do not need.

Yes. OnPay includes benefits administration (health insurance and 401(k)) and integrated pay-as-you-go workers compensation as part of its single plan, with no extra subscription fee for the administration itself. You pay the underlying insurance premiums, but the setup and management sit inside OnPay alongside payroll.

Yes. OnPay supports multi-state payroll, handling withholding and filing across states for employees in different locations, included in the single plan. For a small business with remote employees in several states, this is covered without an upgrade, though you remain responsible for registering with each state's agencies.
