If the bank account I presented in my declaration has been closed, will I still be getting my refund through a mailed check?

If you e-filed:

Banking information for direct deposit is wrong or closed

If you entered incorrect banking information for your refund, you can change it if your return is rejected.  If it is accepted, however, it is too late to change it.  The bank will reject the refund and send it back to the IRS.

If you take NO action—-the IRS will freeze your refund for at least six weeks and then mail you a check.

If your refund is sent back to the IRS—- make certain that the address you entered on your Form 1040 is correct.  And…open all mail, even if it looks like junk mail.

Yes, you will receive your refund by check.  It'll be mailed to the address listed on the tax return.  It takes about 3–6 weeks to receive your check in the mail.
