Loved by law firms

“OnPay has helped to streamline the payroll process for our small law office. We can easily run payroll for direct deposit in a matter of minutes and OnPay handles our 940/941 filings for us. This used to take time away from our practice to deal with our tax filings and payroll manually.”

Frequently asked questions for legal professionals and law firms

  • How much does it cost for me to run payroll for my law practice?

    It’s a single monthly fee of $40, plus $6 per worker for everything OnPay does. No pricing tiers, no sneaky add-ons.

  • Does OnPay handle new hire reporting for me?

    Great question! When you hire new workers, OnPay reports new hires on your behalf to all fifty states, plus DC. New hire reporting is typically completed on Fridays at the close of business.

  • What if I have a combination of W-2 and 1099 workers I need to pay?

    Paying your team doesn’t need to be complicated — no matter who’s involved. Small businesses are hiring a bigger mix of in-house employees and contract workers these days, so we’ll let you process all the workers you need to pay in the same pay run. We also handle the W-2 forms and 1099 filings at the end of the year. And if a worker goes a month without being paid through OnPay, you won’t be charged for them.

  • How long does it take to set up an account and start running payroll?

    You can get set up super fast – we’ll just need some basic details so our team can help assist you with your setup.  And our in-house payroll experts will do all the heavy lifting — from setting up your dashboard to adding your clients and their employees. We’ll even enter any prior wages to make it easy to switch. And can have you up and running in a matter of days.

  • Are you able to integrate with the time tracking software my start-up uses?

    There’s a very good chance we work seamlessly with the time tracking software you use and currently can connect to QuickBooks Time, When I Work and Deputy. Here’s more information on the integrations we offer.
