State tax filing

Why are the wages reported in Box 1 Federal Wages different than Box 16 State Wages?

The amount in Box 16 state wages and Box 1 federal wages are usually the same.  However, CA wages in Box 16 may differ from Box 1 federal wages for the following reasons: 

  • Wages earned in another state. 
  • Medical expenses.  CA allows an exclusion from gross income for certain employer-provided benefits for a taxpayer's registered domestic partner and that partner's dependents.  
  • California does not conform to federal law regarding health savings accounts (HSAs). 
  • CA taxpayers cannot deduct contributions to federal HSA from their California Wages.   It is not excluded as income and is added to the taxpayers CA wages. 
  • Ridesharing benefits
  • Sick pay under FICA
  • Clergy Housing Exclusion 
  • Income is exempt by U.S. treaties (applies to the employees from the country that has treaty with the US). 
  • California and New York do not conform to the federal suspension of exclusion from income for qualified moving expense reimbursements under the 2017 federal tax law, HR.1, Pub. L. 115-97.  CA and New York allow exclusion from income for qualified moving expense reimbursements.
