How to Request a California Sales Tax Extension

by Jennifer Dunn

California sales tax filing extension

We get it. Tallying up how much sales tax you collected in each California city, county and district over every channel you sell on is time-consuming, if not downright painful.

Fortunately, California will – under limited circumstances – allow you to request a 30-day sales tax filing extension. This extension can be requested up to 30 days following your missed filing date.

Why would you want to request an extension?

  • You can neither file nor remit the sales tax you’ve collected on-time.
  • You can remit what you owe on time but need to file your return late. In this case you are still subject to a late filing penalty.
  • You can file on time but need to remit what you owe late. In this case you are still subject to interest on the amount of sales tax collected you haven’t yet remitted to the state.

Keep in mind this is a filing extension and not a payment extension. Even if you are granted an extension on your time to file your California sales tax return, you will still owe interest on any payment that was due.

How to Request a California Sales Tax Extension

  1. Login at the California BOE e-File Website
  2. Once logged in, fill out the “Declaration of Intent to Submit an Online Relief Request”
  3. Select a “Reason for Request”
  4. Select your filing year and period
  5. Enter the title of the person completing this request

You should receive a confirmation number immediately upon sending your request.

Once submitted, your request could be processed immediately, could take up to 30 days or – should it need to be reviewed by BOE Board members, take from 90-120 days. Keep in mind that if this happens you may be liable for penalties and interest during this time if your request isn’t ultimately granted. And that you will be liable for interest on a late payment even if the filing extension is ultimately granted. If your request isn’t granted immediately you can check online at your BOE account.

What to Do After You’ve Requested a CA Sales Tax Extension
