What does IRS Letter 4464C mean?
The IRS manual lists this letter as a questionable refund hold. The IRS is holding your refund while it checks your return.
It wants to confirm your income, withholding or credits before it pays. You do not owe anything because of this letter.
Why did the IRS hold your refund?
Returns that claim large refunds can be held for this review. Returns with numbers that do not match employer records can be held too.
An employer wage form that has not reached the IRS yet is one way that mismatch happens. When you call, a licensed tax pro goes through your return and looks for what triggered the hold.
Is your Letter 4464C real?
A real letter arrives by mail and shows your tax year. The IRS page for understanding your notice or letter lists real notice codes, so you can confirm this code there.
We can confirm it for you too when you call. If you did not file a return at all, someone may have used your number. Our page on verifying your identity with the IRS has the steps.
Never send money to anyone who contacts you about this refund. Our guide to checking whether an IRS letter is real shows what to watch for.
