When you send a Link invitation, Lacerte checks to see if a client with that Social Security number already exists in Link. If the same Social Security number exists in Link, Lacerte then compares the client's email address that exists in Lacerte and Link.

If the Link client has a different email address than the Lacerte client,  you'll receive an error message stating "The primary taxpayer SSN is already used by the firm. Please enter a unique SSN and try again."

Follow these steps to resolve this error:

1. Sign in to Intuit Link.
2. Find the client you're trying to invite.
3. Select the client's name, then select Edit.
4. Change the email address to match the client's email address in Lacerte.
5. Then re-invite the client to Link from Lacerte.

The logic behind this message:

1. Before Lacerte sends the client to Link, it checks to see if a client with the same Social Security number already exists in Link.
2. If a client with the same Social Security number exists in Link, then the program compares the client's email address that is in Lacerte and in Link.
3. If the email address in Lacerte and Link are the same:
   • The Lacerte client merges with the Link client.
   • The invitation/requests are sent to the client.
4. If the Social Security number is the same but the email address is different, then Lacerte returns the duplicate Social Security number message.

If a client already exists on the Link portal, but was never invited to Link from Lacerte, it could be a QuickBooks Online client or a PTO client where SSNs can be entered. This would only occur if PTO, QuickBooks Online, and Lacerte were all on the same realm.
