The Payroll Taxes section allows you to set up all taxes associated with each state where you have employees. States listed will depend on employee worksites and your company location. Each page will look different, depending on the taxes associated with that state. It is important to fill out the information requested in each state so we are able to file and pay those taxes.
Getting started
In Company, click Payroll Taxes.
What information we need you to add
This page varies by state, but you'll generally need to add withholding IDs as well as unemployment account numbers. Any SUI rates that apply to your business must be added by you, as these also vary by company. States can also have surcharge rates that apply in some cases. You can look up tax rates and requirements by state in our resource center.
Updating state tax information
When changes to state payroll tax rates are initiated by the state, you'll need to enter the new rate in OnPay in order to correctly calculate state taxes.
Because tax changes are announced in advance, you're able to schedule the effective date of this change ahead of time (typically, changes go into effect on January 1st of the following year). This ensures a smooth transition to the new rate when the time comes.
Resources for worksites
OnPay will accurately calculate the taxes due based on each employee's assigned worksite. We take the accuracy of our payroll tax calculations very seriously. If you believe something is calculated incorrectly, reach out to us at hello@onpay.com.
We know every state is different. That's why under "Help for Employers", you can open a tax guide detailing local SUI rates and tax requirements, obtaining IDs, and specific requirements for each state you operate in. It even tells you what you need to send to us.
Paying employees in other states?
If you operate in multiple states or just have employees working from home across a state line, it's important to file the correct state forms for those workers. See what forms we file in the states where you pay employees.
If you're looking for more general information about payroll taxes, check out our small business guide to processing payroll or our payroll and tax rate calculator.
Our Tax Accuracy Guarantee
Bottom line: We take the accuracy of our payroll tax calculations very seriously — and our accuracy guarantee ensures we’ll always have your back.
However, because we file on your behalf using information provided by you, it's important that you provide and input accurate information about your company, its employees, and the states and districts in which they live and your business operates, including all IDs and tax rates. Our Tax Accuracy Guarantee picks up where you leave off by covering all our calculations, and the filings and payments we base on them.
In rare circumstances, OnPay may need additional information from you, or may request you take action in order for us to file and pay your taxes. If additional information is requested by us, but never provided by you, any affected tax filings and payments will not be covered by our Tax Accuracy Guarantee.
