The form to request an extension for 2023 is not yet available.  Check back in mid to late March.  An extension does not give you extra time to pay.  Estimated tax due has to be paid by April 15, 2024.  An extension gives you extra time to prepare and file your Form 1040.

Thanks for your very prompt reply and helping me on educating on still paying the taxes if owed by April 15 2024 to avoid any penalty, and that is where my second question is -

Second question:

When e-filing an extension using TT, will TT allow me to pay taxes owed during extension e-filing process? If yes, then what "ALL" payment methods will TT accept during the payment of taxes owed during an e-filing of extension process, please let me know asap, thanks as I want to use ONLY TT for paying owed taxes using credit card instead of going to IRS website and paying from there. Thanks.

You can pay your estimated tax by a  variety of methods including by direct debit, using a credit card on the IRS site or by mailing a check or money order.  Not sure what you have against using the IRS site.

There is nothing against using IRS website, it is about an integrated and seamless process as we are using TT for this extension e-file process when it becomes available so using it at the same time and pay through TT is more convenient and seamless.

Also, mind sharing the details, if we can e-file extension using TT and then pay thorough IRS website, does TT allows that, I mean it must give us an option to do so? And, instead of going through two steps was wondering if TT accepts Credit Card payment for the taxes owed when using TT easy e-file extension process?

Please advise. 

Please advise based on your previous years of experience if TT accepts credit card payment method when paying for taxes owed during e-file of an extension?

Please advise based on your previous years of experience if TT accepts credit card payment method when paying for taxes owed during e-file of an extension OR

TT only e-files an extension and once it gets approved and accepted by IRS then we have to go to IRS website for making any payments?

I am unaware of this TT extension filing process, would be helpful to know all the above details. Thanks.

Thanks once again for your response and sharing the link, as I am going through the link it has the below steps -

And, as you can see in the BOLD bullet point below, it says make a payment using checking or savings account,

so, the question still remains, will TT accept Credit card payment or we have only two options as below checking or savings account?

Please advise. Thanks in advance.

Need to use a credit card to pay taxes owed?

If you've e-filed or mailed Form 4868 and need to pay by credit card, you can use one of several IRS approved Electronic Payment Methods. You can pay with your debit or credit card online or by phone. File your complete return by October 15, 2024.

Cautions

• If the IRS thinks your estimate of the amount of tax you owe is unreasonable, it may disallow your extension and assess a late-filing penalty.
• If you underestimate the amount of tax you owe, you'll likely have to pay interest and perhaps penalty on whatever amount you fail to pay by the original filing deadline.
• If you pay less than 90% of the tax you owe, you'll end up owing a penalty of 0.5% of the underpayment every month until you pay the remaining balance. For example, if you pay $600 by the original filing deadline, but discover when you complete your return that you really owe $1,000, you will usually owe 0.5% per month on the $400 that is overdue, or about $2 a month, until you pay the full amount owed.
