California - How to Apply Refund to Estimated Tax Payments

If a taxpayer owes additional taxes to California during the year, they may be required to make estimated tax payments for the following tax year. In some cases, this may result in a refund, which they may choose to apply toward the following year's estimated tax payments.
 

To apply an California refund to the next year's estimated tax payments, from the main menu of the California return select:

• Refund
• Enter the state refund amount to apply to your 20XX tax return
