🔍 Previously had ITIN - Previously had ITIN, now has SSN. Which to use?
Once you are issued an SSN, this guide explains which number to use when filing your tax return.
⚠️ Before You Begin
Make sure you know which identifier you were previously using (ITIN) and which identifier you have now been issued (SSN).
📊 Step-by-Step Guide
Step 1: Use your SSN to file your tax return
Use this when you have been issued an SSN.
Once you are issued an SSN, use it to file your tax return.
Use your SSN to file your tax return even if your SSN does not authorize employment or if you have been issued an SSN that authorizes employment and you lose your employment authorization.
Step 2: Stop using your ITIN
Use this when you previously used an ITIN but now have an SSN.
An ITIN will not be issued to you once you have been issued an SSN.
If you received your SSN after previously using an ITIN, stop using your ITIN. Use your SSN instead.
