What message do you get when you use the IRS "Where's My Refund" tool that xmasbaby0 mentioned above to check your Federal refund status?

If you end up needing to contact the IRS, why are you unable to do so? If you are located in the USA, we can tell you the steps to reach domestic IRS customer support by phone.
If you are located in another country, we can tell you how to reach the IRS International Taxpayer Service Call Center.
