@sdc4
go to the IRS payments page where you can file for an extension right now and make a payment ( $5.00 will do).
If you know you will owe you need to pay at least 90% of the tax due to avoid penalty
approval is automatic.
OR get the form and mail it in .
No tax software is required.
When you file there is a line for "payments made with request for extension of time"
Any tax software will be able to handle this even free software.
