If I e-filed and owed taxes, but I am sending in a check for the taxes owed, do I have to also send in a copy of my 1040 return?

[VolvoGirl · Accepted solution]

No, not the whole return.  There should be a 1040V voucher to mail with the check.  Don't wait for the IRS to send you a bill.  Payment is due by tomorrow April 18 or they will start adding interest to it.

Better make sure you efile was Accepted.  You can check your efile status here     <a rel="nofollow" target="_blank" href="https://turbotax.intuit.com/tax-tools/efile-status-lookup/">https://turbotax.intuit.com/tax-tools/ef...>

Or make an online payment at <a rel="nofollow" target="_blank" href="http://www.irs.gov/payments">www.irs.gov/payments</a>.  You don't need the paper voucher because you will use your SSN on the online site to link the payment to your tax account.  You can use direct bank debit (for free) or a credit card (for a service charge).  Just be sure to select "2016 form 1040" as the reason for the payment (and not 2015 back taxes or 2017 estimated taxes.)
