we have one son who is working part time and full time college, shall we file jointly with us or do we have to file separately !

[KrisD · Accepted solution]

You and your spouse would fie Married Filing Jointly (MFJ), claim your son as a dependent, claim his exemption, and claim his 1098-T (education expenses) to apply for an education credit.

Your son would file his own return, but he needs to elect "Someone else can claim me".
