What Form 3582 (2021) Is For
Form 3582 (2021), officially titled Payment Voucher for Individual E-filed Returns, is used by taxpayers who electronically file their California income tax returns and owe a balance to the state. This form serves as a payment voucher that accompanies a check or money order, ensuring the Franchise Tax Board (FTB) correctly applies the payment to the taxpayer’s e-filed return. It applies to California Forms 540, 540NR, and 540 2EZ. Taxpayers should not use Form 3582 if they have no balance due or if they are paying electronically through Web Pay, electronic funds withdrawal, or credit card.
When You’d Use Form 3582 (2021)
You should use Form 3582 (2021) in the following situations:
- Original e-filed return with balance due: Use this form only if you filed an original California individual income tax return electronically and have a balance that must be paid.
- Paying by check or money order: This form is required when you choose to mail a check or money order instead of using an electronic payment method.
- Received e-file acceptance: Wait to submit the form until the Franchise Tax Board has confirmed acceptance of your electronically filed return.
- Cannot use electronic payment methods: Taxpayers not subject to mandatory electronic payment requirements may use Form 3582 to pay by mail.
- Partial payment submission: You may use this form to submit a partial payment toward your total liability if you are unable to pay the full amount owed.

Common Mistakes and How to Avoid Them
Taxpayers should avoid these common errors when using Form 3582 (2021):
- Mailing the form with no balance due: Do not complete or send Form 3582 if your return shows no tax liability, as this causes unnecessary processing and confusion.
- Using it for amended returns: This form is valid only for original e-filed returns; for amended returns, use Form 3582X instead to ensure proper payment processing.
- Mismatched information: Verify that the details on your voucher exactly match those on your e-filed return, especially names, Social Security Numbers, and payment amount.
- Violating electronic payment rules: If you meet California's mandatory e-payment thresholds, submitting Form 3582 may result in a one percent noncompliance penalty.
- Including a paper return: Never attach a paper copy of your e-filed return to this form, as doing so can delay processing and misapply your payment.
- Missing the payment deadline: Filing your return does not extend the payment due date. Send payment by the April 18, 2022, deadline to avoid penalties and interest.
What Happens After You File
After you submit Form 3582 (2021) with your check or money order, the Franchise Tax Board processes your payment. It matches it to your e-filed return using the identifying information on the voucher. Most payments are credited within two to four weeks during peak tax season. You can verify receipt through your MyFTB account or by contacting the FTB directly. If any errors or mismatches occur, you may receive a letter requesting clarification.
Interest will continue to accrue on unpaid balances until full payment is received. You may be eligible for an installment plan if you cannot pay the full amount immediately.
