# Tax notices

Understand tax notices and how Avalara assists with their resolution.

Tax jurisdictions may issue tax notices to clients for various reasons, such as discrepancies, missing payments, or adjustments. These tax notices may relate to returns filed by Avalara on behalf of a client.

If a tax notice applies to a filing period for which Avalara was responsible, the client can submit the tax notice to Avalara for investigation and resolution.
