Line 4 – Refund
Enter the Refund from your amended tax return.

Line 5 – Tax Paid with Original Tax Return
Enter the amount actually paid with your original tax return. Also, include any additional payments of tax made after the original tax return was filed. Do not include payments of interest or penalties.

Line 7 – Amount You Owe

You may also pay by credit card. Call 800.272.9829 or go to the Official Payments Corp’s. website at officialpayments.com and use the jurisdiction code 1555. Official Payments Corp. charges a convenience fee for this service.

Or, if you are not required to remit all your payments electronically, make a check or money order payable to the “Franchise Tax Board” for the full amount you owe.

Enclose, but do not staple, your check or money order to your amended tax return.

Make all checks or money orders payable in U.S. dollars and drawn against a U.S. financial institution. A penalty may be imposed if your payment is returned by your bank for insufficient funds.

If you are including penalties with your payment, enter the amount of penalties on line 8a. Also, attach a statement to your tax return that shows the following information for each type of penalty included on line 8a: type of penalty (description); the Internal Revenue Code (IRC) or California Revenue & Taxation Code (R&TC) section that provides for assessment of the penalty (if possible); and a schedule showing how you computed the penalty.

Line 8b – Interest
If you owe additional tax (line 7) and are including interest with your payment, enter the interest on line 8b. If you do not include interest with your payment or include only a portion of it, the FTB will figure the interest and bill you for it.

Line 8c – Total Interest and Penalties
Enter the total of line 8a and line 8b.

Line 10 – Amount You Want Applied to Your 2019 Estimated Tax
Enter on line 10 the amount from line 9 you want applied to your estimated tax for 2019. You can apply all or part of the amount on line 9 to your 2019 estimated tax.

You will be notified if any of your overpayment was used to pay past due debts so that you will know how much was applied to your estimated tax.

Line 11 – Refund
If you are entitled to a refund greater than the amount claimed or allowed on your original tax return, your Schedule X should show only the additional amount due to you. This amount will be refunded separately from the amount allowed on your original tax return. The FTB will figure any interest owed to you and include it in your refund.

Adjusted Refunds – If there is a change made to your refund, you will still receive your refund via direct deposit. For more information on direct deposit of adjusted refunds, go to ftb.ca.gov and search for direct deposit.

Mail your amended tax return and attached Schedule X to:
