Why this matters
Most state tax portals send a one-time code every time someone logs in. Adding your Zamp state portal email (which ends in @zamp-customer.com) to each portal lets Zamp log in and file on time without waiting on you for a code. You can set up your Zamp state portal email to forward to your email so you will still retain access to your portals.
Step 1: Find your Zamp state portal email
1. Log in to app.zamp.com and click Company in the left sidebar.
2. Select Settings.
3. Under Who gets these emails, click Add recipient and add your own email. This forwards 2FA codes to you, so you can finish setup.
4. Copy the address under Your state portal email (ending in @zamp-customer.com). This is the email you will add to your state portals.
Zamp's 2FA contact details
Method | Use this |
Your Zamp state portal email (ends in @zamp-customer.com) | |
Phone (text message) | (786) 730-2855 (only required where noted below) |
Before you begin
☐ Your username and password for each state portal
☐ Access to the email or phone currently set up for 2FA (you will need a code to sign in)
☐ Email forwarding from your Zamp state portal email set up to go to your email (Step 1, item 3 above)
☐ Whether a previous provider still has a filing due this period (see the note below)
Important: don't remove a previous provider before their last filing. Some states allow only one 2FA email (marked Yes in the table below). In those states, switching to Zamp’s email removes the previous provider’s access. If they still have a return to file, it could be late and trigger penalties and interest. Wait until their final filing is confirmed before removing the previous provider’s email. |
Step 2: Find your state
Click the state name to open its portal, then click the instructions link to jump to the steps for that state. If your state is not listed, it does not currently require 2FA setup, so just share your login details with Zamp and we’ll take it from there.

* California, Connecticut, Minnesota and Wisconsin allow only one 2FA email. If a previous provider is still filing, add Zamp’s phone number (786) 730-2855 instead of changing the email, and ask your Zamp specialist for the code.
**Kansas, Kentucky, Maryland, and Rhode Island allow only one 2FA email. If a previous provider is still filing, please wait to update the email until after the last return is filed.

Before you start, message your onboarding specialist or account manager so they are ready to send you the code. |

2. Scroll to Multi-Factor Authentication and select Text Messages. Enter 7867302855 as the Mobile phone number and click Send Code.

Troubleshooting and FAQ
My username or password doesn't work.
Use the portal’s “Forgot username/password” link to reset it, then send the updated credentials to your Zamp specialist. Zamp can’t file until we can log in.
The portal says my password has expired.
Reset it on the portal and share the new password with Zamp. If a previous provider still files for you this period, let them know too.
My account has been deactivated.
Call the state’s tax department to reactivate it. Some states will only speak with the account owner.
I set up email forwarding from my own email to Zamp instead. Is that enough?
Not reliably. Forwarded codes often arrive late or not at all. Adding your Zamp state portal email or (786) 730-2855 directly in the portal is more dependable.
The code is going to an old provider or a number I don't recognize.
Log in, open the security settings, and add or switch to Zamp’s details using the steps above. If you can’t receive the code to log in, contact the state to update your 2FA contact.
Will I lose access to my own account?
No. As long as you add your email as a recipient in your Zamp Company Settings, you will also receive the email codes.
