I e-filed my Taxes. Four Tax Vouchers are listed on my paperwork but I did not select a payment plan option. My Payment total includes a Penalty/Interest amount even though I authorized complete payment before 4/15/24. Why am I being charged a Penalty/Interest Fee?
If you owed a large amount this year, those 4 1040ES vouchers are for Pre-Paying your 2024 taxes.....and are not for what you owe for 2023 that you are filing now.
Those forms can be ignored if you are sure you will be paying enough during 2024, thru withholding, such that it covers this 2024 year's taxes such that you will not owe more than $1000 at tax time when you prepare your 2024 taxes. The fact that those 1040ES forms were prepared, is not sent to the IRS, so they are not expecting them to show up.

Penalties and interest assessed on your 2023 tax return is usually the result of default calculations indicating you "might' have upderpaid during one or more calendar quarters of the 2023 tax year. This can result if you owed more than $1000 at tax time.....it can even happen if you get a refund, but made any uneven quarterly estimated tax payments during the year. The penalty&interest charge can sometimes be reduced or eliminated by filling out the form 2210/2210AI. Where you define all your income, tax payments, deductions, withholding etc...etc.. by quarter (3mos, 2mos, 3mos 4mos)...but if penalty/interest assessed is less than ~$50 I don't bother because the work involved gathering all that data isn't worth the effort (~$50 is my limit)
