I had to amend my fed tax return, and now owe less ,but can't print a new voucher, so how do I pay the lesser amt. ?

[mcecilecurtis01]

Do I have to pay the old larger amount, and then get a refund for the difference, or can I just pay the amended amount ?

You can just pay the lesser amount if you file the 1040X by 4/18/17 ... do not use the voucher ... just attach a check or pay online here... https://www.irs.gov/payments

Make sure the amended return is correct since you didn't pay the original amount yet ...

Column A should have the figures from the original return, Column C the corrected figures and Column B the differences between the other 2 which needs an explanation on page 2 of the form 1040X.

If you completed it correctly you will see an entry on either line 16 OR 18:

On line 16 should be the amount you paid with your original return.
On line 18 should be the amount of your original refund you received.

Then you will see your extra refund on line 22 OR  the new balance due you need to pay on line 20.
