Payroll Tax Registration Requirements
Updated: Sep 5
What Payroll Providers Need Before You Run Payroll
Before payroll can be processed, employers generally need to complete the applicable state payroll tax registrations and provide their payroll provider with the required state account information.
Depending on the state and your business circumstances, this may include state income tax withholding (SIT) and state unemployment insurance (SUI/UI) accounts.
Whether you are hiring your first employee, expanding into another state, or setting up payroll with Gusto, ADP, QuickBooks Payroll, Paychex, or another payroll platform, having the correct state registration information ready can help prevent payroll setup delays.
What Payroll Tax Accounts Does a Payroll Provider Need?
The exact requirements vary by state, but employers may need to obtain applicable state payroll tax accounts before payroll processing begins.
1. State Income Tax (SIT) Account
A state income tax withholding account is used to withhold and remit state income taxes from employee wages where applicable.
Not every state imposes an individual state income tax, so withholding registration requirements vary by state.
2. State Unemployment Insurance (SUI/UI) Account
A state unemployment insurance account is used to report employee wages and pay applicable state unemployment taxes.
Employers may need to register for unemployment insurance when they become subject to a state's unemployment requirements.
3. Other State or Local Payroll Accounts
Depending on where employees work, a business may also have additional state or local employer tax registration requirements.
This is especially important for businesses with employees working in multiple states or remote employees.
Why Do Payroll Providers Ask for State Tax Account Numbers?
Payroll providers typically need the applicable state tax account information to properly configure payroll and tax filings.
Once your state registrations are completed, your payroll provider may need information such as:
State withholding account information
State unemployment insurance account number
State unemployment tax rate
State registration details
Applicable local tax information
Other state-specific payroll information
Providing accurate information helps your payroll provider configure the account correctly and determine where payroll taxes need to be reported and paid.
Why Are Payroll Registration Services Charging $299+ Per State?
Many payroll providers and payroll compliance firms offer state payroll tax registration services as an additional service.
Depending on the provider, registration assistance may involve:
Completing state registration applications
Gathering employer information
Submitting registration applications
Communicating with state agencies
Following up on applications
Obtaining state account information
Providing account information to the payroll provider
The cost of registration assistance can vary significantly between providers.
For businesses registering in multiple states, these fees can add up quickly.

How the Payroll Registration Process Works

Step 2: We Prepare and Submit the Registration
We prepare the applicable state payroll tax registration application and submit it according to the state's registration process.
Step 3: The State Processes the Application
State processing times vary by state and agency. Some registrations may be processed quickly, while others may take longer.
Step 4: Receive Your State Account Information
Once the state processes the registration, you receive the applicable account number, registration information, and other available state details.
Step 5: Provide the Information to Your Payroll Provider
The applicable state account information can then be provided to your payroll provider for payroll setup and tax filing configuration.
Step 6: Start Processing Payroll
Once your payroll account is properly configured and other payroll requirements are complete, your payroll provider can begin processing payroll.

What Happens If You Start Payroll Before Registration?
Starting payroll before completing required state registrations can create unnecessary compliance and administrative issues.
Depending on the state and circumstances, employers may experience:
Payroll setup delays
Filing complications
Incorrect tax withholding
Missing state account information
Late registration issues
Additional correspondence from state agencies
Difficulties configuring the payroll system
For this reason, businesses should evaluate state registration requirements before processing their first payroll in a new state.
Multi-State and Remote Employee Payroll Registration
State payroll registration becomes particularly important when a business expands into multiple states.
For example, hiring a remote employee who works from another state may create new state payroll tax registration requirements.
A business that previously had employees in only one state may need to evaluate:
State withholding registration
State unemployment insurance registration
Local payroll tax requirements
Employer registration requirements
Payroll system configuration
State tax filing obligations
Requirements vary by state, so businesses should evaluate each employee's actual work location and applicable state rules.
