My son has yet to receive his SSN because I am stationed over seas is there a form that I should fill out?

Yes:

• Complete and sign an Application for a Social Security Card (SS-5-FS)
• Take or mail your signed application and documents to any U.S. Embassy or Consulate. 
  

In the meantime, you can file an extension by April 15th and pay any estimated tax payments.
