Arkansas payroll tax and registration guide

Why is this important?

To maintain compliance with state payroll tax regulations, you must provide the following information before you can use OnPay to run payroll:

• State Employer Identification Number and state/local tax IDs
• Tax rates - State tax offices set these rates based on the type, age, and size of your business
• TPA and power of attorney - Most tax offices require this before we can submit quarterly wage reports and deposits on your behalf

This information must be provided and maintained by you in order for OnPay to accurately file and deposit tax payments for your company. OnPay is not responsible for any penalties or interest that incur due to missing or incorrect company tax information.

Each state has its own requirements, so if you pay employees in more than one state, you’ll find separate tax guides for each state.

See what information you need to provide OnPay, and what taxes and filings OnPay handles for Arkansas Employers.

Where you can find the tax account numbers needed

If you are an existing employer who has previously run payroll in Arkansas, you likely already have the IDs and online accounts needed for OnPay to process your tax filings.

If you are a new employer in Arkansas, you will need to register your business with the Arkansas Department of Finance and Administration and the Arkansas Department of Workforce Services. This must be completed for OnPay to be able to file and pay your Arkansas taxes.

Withholding Tax Account Number, Zip Code, Last Tax Payment, and Deposit Frequency

Existing Arkansas Employer: 

• You can find your Withholding Wage Tax Account Number and deposit frequency on payment vouchers or registration notices from the state agency. 
• Deposit frequency will be monthly, unless notified by the Commissioner of Revenue of any change in frequency. 
• The Withholding Tax Section will reclassify accounts to an annual filing status (once an account has established a filing history) if the tax deposits are less than $1,000.00 in a reported period. 
• Zip Code: This is the zip code that is registered with the Arkansas Department of Finance and Administration. If the zip code does not match the zip code as registered with Arkansas, our access to your account will be denied. 
• Last Withholding Wage Tax Payment: This is the last payment completed on Arkansas TAP for Withholding Wage Tax.

New Arkansas Employer: Register with the Arkansas Department of Finance and Administration (501)-682-7290

• Deposit Frequency - All new registrations are classified as “monthly filers” and will report accordingly until notified by the Commissioner of Revenue of any change in classification
• You will need to register with this department if you have employees that both live and work in Arkansas, or for any employees that calculate Arkansas withholding taxes regardless of where they live/work
