Are others in the community getting "penalty" notices from the IRS because TT didn't let you file a 2210 form to explain uneven income?

I'm told the online versions of TT don't let you use the 2210 form if its algorithms don't detect a problem as simple as uneven income. I now need to file a federal amended return to with a 2210 form to explain why I don't owe a penalty

BTW if you got a penalty notice that means IRS assessed a different penalty from that calculated in Turbotax on Form 1040 Line 38 based on what was input. Form 2210 is not filed by default unless you adopt an exception method, and IRS calculates penalty based on information it has in their system (see Form 2210 Part I), you can even opt to not calculate a penalty by leaving 1040 Line 38 blank and have IRS do it for you.

Your income is assumed to be even by default unless you file 2210 AI method. But absent Form 2210 AI, if IRS arrived at a different result then there is some difference in the data - either an adjustment/amendment to 2024/5 not known to Turbotax, withholding or estimated tax was entered incorrectly or simply a difference in when the final tax payment was recorded etc. You can check your transcript and payment history at irs.gov to see where IRS may have differed to what was entered into Turbotax.

If you did have uneven income you can file an amendment to adopt 2210 AI method to try and reduce the penalty, but if you have some discrepancy vs IRS with the default method, I would first try to determine what that is.

If you have a penalty you need to work through options for filing 2210 under Other Tax Situations / Underpayment Penalties to try and reduce it. Not sure what you were "told" but Turbotax should let you do it - neither IRS nor Turbotax have any information to determine that your income was even or uneven, until you fill in the details for 2210 Annualized Income method (other than uneven estimated tax payments which is the only thing entered with dates).

Thank you for your replies. I’ve long understood that the IRS assumes level income throughout the year, that a 2210 form explains uneven income (and and corresponding uneven tax payments), and the impact of Roth conversions creates uneven income / tax events. The trap I fell into is that Turbo Tax reported that their “proprietary algorithms” had determined that the 2210 would not be required. I used the AI tool to confirm this determination. Unfortunately the algorithms were not correct and the IRS sent be a bill. I’m now compelled to resubmit my forms with a 2210 included to recover the penalty.

This brings up a second issue. Apparently (and confirmed by the AI agent) the 2210 form is visible but not submittable when using the the Premier version of TT that I purchased at Costco and is sold in so many other retail stores. The AI agent indicates that I need the “desktop edition” which is available from TT’s site for another $100+.

Sooo… I’m left wondering how many people have run into both the “proprietary algorithms” and “desktop edition” issues and if they have found suitable workarounds. This would be a concern to almost anyone making Roth conversions as well as several other situations.

Can you clarify what version you used - if you purchased “Premier” from Costco that is the desktop edition and has the menu for Income, Deductions etc horhzatonally across the top of the screen.

You can also pre-purchase online versions (Fed only) this year but that would be called “Premium” and has the menu down the left.

AI may be causing more confusion here. Form 2210 is not filed by default per IRS instructions unless you have an exception in Part II. On desktop you can see it in Forms mode which online doesn’t have. The one limitation of TT I’ve noticed is that Form 2210 is not included in the PDF with all forms and worksheets. But you shouldn’t need desktop to file AI method, this is handled regardless of version through Other Tax Situations / Underpayment Penalties.
