State W-2 Filing
Overview
When you file W-2 information with the Social Security Administration (SSA), the file includes state wage and tax information through the "RS" record. Many states have information-sharing agreements with the federal government, which may eliminate the need for separate state filing.
State Information in Federal W-2 Files
The RS Record
The W-2 file created by ProPay for SSA submission contains an "RS" (State) record that includes:
- Employee's wages subject to state withholding
- State income tax withheld for the year
- Employer's state ID numbers
- State unemployment insurance (SUI) details
- Local tax information (where applicable)
What SSA Does with State Data
Although SSA processes federal wage information, the RS record is included specifically for states:
- SSA ignores the RS record for federal purposes
- SSA shares the RS record data with participating states
- States use the information to verify state tax filings and compliance
State Filing Requirements
Federal-State Information Sharing
Important: A majority of states now have agreements with the federal government to exchange W-2 information.
What this means:
- In many cases, filing with SSA fulfills your state W-2 filing requirement
- You only need to file once (federally through SSA)
- States receive the data automatically through information sharing
Verify Your State's Requirements
Always check with your specific state because:
- Not all states participate in information sharing
- Some states require additional reporting beyond W-2 data
- State deadlines may differ from the federal January 31st deadline
- Some states have specific format or submission requirements
How to Determine Your State's Requirements
Check State Department of Revenue
Contact your state's tax authority:
- Visit your state's Department of Revenue website
- Look for employer tax information or W-2 filing requirements
- Check for information-sharing program participation
- Review state-specific W-2 filing instructions
Common State Scenarios
Scenario 1: State Accepts Federal Filing Only
- File W-2 information with SSA
- No additional state filing required
- State receives data through information sharing
Scenario 2: State Requires Separate Filing
- File W-2 information with SSA (federal requirement)
- Also file separately with your state
- May use same file or state-specific format
Scenario 3: State Accepts Federal Filing with Additional Report
- File W-2 information with SSA
- Submit supplemental state report
- State report may cover unemployment or other state-specific data
State-specific Considerations
State ID Numbers
Ensure your state employer ID numbers are correct in ProPay:
- Go to Client Functions > Edit/Change Client
- Review state tax identification numbers
- Verify numbers match your state registrations
- Correct any discrepancies before generating W-2 files
Multiple States
If you have employees working in multiple states:
ProPay handles this automatically:
- Creates separate RS records for each state
- Allocates wages to appropriate states
- Reports state withholding for each jurisdiction
Your responsibility:
- Verify state withholding calculations are correct
- Check that state ID numbers are entered for all states
- Confirm filing requirements for each state
Local Taxes
Some states and localities require local tax reporting on W-2s:
- City or county income taxes
- School district taxes
- Local services taxes
ProPay includes local tax data in the RS record where applicable.
States With Special Requirements
States Requiring Separate Filing
Some states that may require separate W-2 filing (verify current requirements):
- Contact individual state revenue departments for current requirements
- Requirements change periodically
- Some states have transitioned to federal information sharing
State electronic filing specifications
States requiring separate filing may specify:
- Unique file format requirements
- Different submission portals
- Additional data elements beyond federal RS record
- Alternate deadlines
Check state guidance for technical specifications if separate filing is required.
Creating State W-2 Files in ProPay
ProPay automatically includes state information when you create federal W-2 files:
No Additional Steps Required
- Enter state wage and tax information during regular payroll processing
- Create W-2 files as usual (see "E-file W-2s" topic)
- State data is automatically included in RS records
- Submit to SSA
Verify State Data
Before filing, review state information:
- Print W-2 preview reports in ProPay
- Verify state wages match state quarterly reports
- Confirm state withholding totals are accurate
- Check that correct state ID numbers appear
State Filing Deadlines
Federal Deadline
- January 31st - Annual W-2 filing with SSA
State Deadlines
State deadlines vary:
- Many states: Follow federal January 31st deadline
- Some states: Have different deadlines (earlier or later)
- Quarterly filers: May have additional quarterly requirements
Always verify your specific state's deadline.
State Unemployment Reporting
Separate from W-2 Filing
State unemployment insurance (SUI) reporting is typically separate from W-2 filing:
- File quarterly wage reports with state unemployment agencies
- W-2 filing does not replace SUI quarterly reports
- Some states verify W-2 data against SUI filings for compliance
Consistency is Important
Ensure consistency between:
- Federal W-2 filing (through SSA)
- State W-2 filing (if required)
- State quarterly unemployment wage reports
Discrepancies may trigger state audits or inquiries.
Troubleshooting State Filing
State Rejects Federal Information
Problem: State claims they didn't receive W-2 data from SSA
Solutions:
- Verify your state participates in information sharing
- Confirm you filed with SSA successfully
- Check that state ID number in W-2 file is correct
- Contact state revenue department for guidance
- File directly with state if required
Incorrect State ID Number
Problem: Used wrong state ID number in W-2 filing
Solutions:
- File corrected W-2c forms with SSA
- Contact state revenue department about the error
- Update ProPay with correct state ID
- Implement verification process for future filings
Missing State Data
Problem: State information not included in W-2 file
Solutions:
- Verify state wages and withholding were recorded in ProPay
- Check that state tax setup is complete for client
- Regenerate W-2 file after adding missing data
- Revalidate with AccuWage before submission
Multiple State Allocation Issues
Problem: Wages not correctly allocated between states
Solutions:
- Review employee state assignments in ProPay
- Verify state withholding calculations
- Check that employees are assigned to correct work states
- Consult with tax professional if complex multi-state situation
Best Practices
Annual State Requirement Review
Each year before W-2 filing:
- Check for changes to state requirements
- Verify participation in federal information sharing
- Review state deadlines
- Update ProPay with any new state ID numbers
Maintain State Registrations
- Keep state employer registrations current
- Update address changes with state agencies
- Renew registrations as required
- Maintain documentation of state ID numbers
Document State Filing Compliance
Keep records showing:
- State filing requirements research
- Confirmation of federal filing (SSA receipt)
- State filing confirmations (if filed separately)
- Correspondence with state agencies
Reconcile Regularly
Throughout the year:
- Reconcile state withholding to state quarterly reports
- Verify state wage totals match W-2 annual totals
- Correct discrepancies before year-end
- Maintain supporting documentation
Common State Questions
Do I need to file separately with my state?
Check your state's Department of Revenue website or contact them directly. Requirements vary by state.
Will SSA send my W-2 data to all states?
SSA shares data with participating states. Not all states participate. Verify with your specific state.
What if I have employees in multiple states?
ProPay handles multi-state reporting automatically. Ensure all state ID numbers are entered correctly and verify each state's filing requirements.
Can I file state W-2s before federal?
You can file with your state first if required, but federal filing with SSA is mandatory by January 31st regardless of state deadlines.
What if state and federal W-2 amounts don't match?
This can occur legitimately if state and federal wage definitions differ (e.g., 401(k) contributions, certain fringe benefits). Consult a tax professional if unsure.
