A filled-in Form 540 example: a single filer enters name and address

Form 540 example filled out, example: a single filer enters name and address
Jane Ann Sample files Form 540 2EZ as a single California resident. Her address is her principal residence, so principal residence address stays empty and she files alone. She is not amending the return, so the AMENDED box stays empty. Nothing goes in spouse's/RDP's names because she files alone. Her California filing status matches her federal one, so Filing status different box stays empty. No one can claim her as a dependent, so that box stays empty. She has no foreign address and no prior name, so those boxes stay empty. The year spouse/RDP died box stays empty because she is not a qualifying surviving spouse/RDP. Nothing goes in Exemptions, Income, Taxable income and credits, Payments and use tax, Health care coverage, Balances, Contributions, Amount you owe or refund, Direct deposit, Voter info, Organ donor election or Paid preparer because the example covers page 1 only. The picture shows page 1 only, and none of its entries is real.
