- When is my return considered filed?
We consider your return filed as soon as we send you a confirmation page with your Declaration Control Number (DCN). Generally this takes less than two minutes after you submit your return. Be sure to print the confirmation page or record your DCN for your records.
- What is a Declaration Control Number (DCN)?
In CalFile, a Declaration Control Number (DCN) is the identification number we assign to your e-file return as soon as we accept it for processing. You can use this number to check the status of your e-file return. You should either print the confirmation page with your DCN or write your DCN your California Online e-file Return Authorization for Individuals form (FTB 8453-OL or FTB 8453).
- What do I need to mail to the Franchise Tax Board?
Generally, nothing. You keep your completed return with your other tax documents (e.g., Forms W-2, W-2G, 1099-DIV, 1099-INT, 1099-R) and your California Online e-file Return Authorization for Individuals form (FTB 8453-OL or FTB 8453). Do not mail these to the FTB.
However, if you owe money and do not choose one of our electronic payment options, you must mail your payment with a Payment Voucher for Individual e-filed Returns (form FTB 3582). We provide this voucher with the final copy of your return.
- What do I need to do after I e-file my return?
We recommend that you close your browser when you are done to ensure the highest level of security.
You need to keep your completed return, other tax documents (e.g., Forms W-2, W-2G, 1099-DIV, 1099-INT, 1099-R), and California Online e-file Return Authorization for Individuals, for four years from the due date of the return or four years from the date the return was filed, whichever is later.
If you owe money and did not send your payment with your return, you still need to pay the amount you owe. We offer several payment options.
- I forgot to print my return before I e-filed. Can I get a copy?
You cannot go back and print a copy of your return after you e-file. To get a copy of your return you will need to complete side one of a Request for Copy of Income Tax or Fiduciary Return, form FTB 3516, and mail it to the address on the form. We generally charge a fee for each request.
- I found a mistake after I e-filed my return. What do I do?
If you need to change your filing status, income, credits, tax amounts, or payments, you will need to complete an Amended Individual Income Tax Return (Form 540X). You cannot use CalFile to correct your return.
