December IRA to Roth Conversion & 60-Day Rollover

Looking for some clarification. My 2025 MAGI will be over $260k once I complete a $40k Roth conversion this month (Dec 2025). If I withhold 24% of the conversion, only $30,400 rolls into my Roth and the remaining $9600 pays the federal taxes. Some questions:

1) I'm assuming since I do a withholding, there's no underpayment penalty? Am I correct?

2) Can I then use my separate savings account to put $9600 into the Roth (60-day rollover) and not incur any penalty? This way, I get the full $40k into the Roth.

3) Is that $9600 capped because my MAGI is large this year? In other words, is the $9600 considered a Roth contribution, rollover, or what is it actually? I think it's a rollover because I'm assuming the 60-day rollover allows this, but this is where I get confused.

4) How will TT treat the $9600 rollover? There's no document because I'll be using my bank account.

I do realize this rollover strategy is only allowed once in 12 months. I didn't do this last year so I think I'm good there.

Many thanks to all!!

1. Yes.

2. Correct.

3. No, the $9600 is not a contribution, it's a rollover. Make sure you tell the plan that it is a rollover/conversion and not a contribution. You have 60 days from rolling over the main portion to send in the extra $9600. Just tell the Roth trustee that this is a rollover, they don't need to know it is part of the other conversion. Because this counts as an "indirect rollover", you can only do this once per 365 days.

4. When you enter the 1099-R, Turbotax will ask what did you do with the money. You answer that it was all converted to a Roth.

If you don;t have withholding, you can probably avoid a penalty by including form 2210 with schedule AI on your tax return. This form tells the IRS that although your tax payments were uneven, your income was also uneven.

Also note (for future conversions) that the timing rules work in your favor if you do the conversion between January and March. If you convert between January 1 and March 31, you don't need do withholding, and instead you owe 1/4 the estimated amount on April 15, June 15, Sept 15 and Jan 15. That allows you to hold some of the money back and invest it elsewhere in the mean time.

I should have said that if you choose to not have withholding, you need to make an estimated payment by January 15 (you can do this online at www.irs.gov/payments) and then also include form 2210 with schedule AI with your tax return.

Roth conversions such as this are not involved in the once-per-12-months rollover limitation. Only traditional IRA-to-traditional IRA and Roth IRA-to-Roth IRA rollovers are involved in this limitation.

With regard to making a separate Roth IRA contribution, the amount converted to a Roth IRA ($40,000 if the entire $40,000 ends up in the Roth IRA) is subtracted from AGI when determining your MAGI for this purpose. In other words, the amount converted to a Roth IRA has no impact on the amount that you are separately eligible to contribute to a Roth IRA.

Completely agree with your assessment. Traditional IRA to Roth conversions are not bound by the once per year limitation.

However, in my case, I am performing the IRA to Roth (not bound by the 12-month rule) and then, I'm performing a cash to Roth 60-day rollover (bound by the 12-month limitation).

My rationale:

1) I want to perform the IRA to Roth and have withholding to avoid any penalties.

2) The withholding reduces the amount that lands in the Roth so...

3) I'll add cash to the Roth to make up the difference (treated as a 60-day, once in 12-month rollover).

4) I'll avoid the form 2210 AI that many people seem to shy away from. I may use the 2210 next year but I'll have a whole year to get smarter on that.

Many thanks for your input. Appreciate the knowledge from all the people in this community.

"I'm performing a cash to Roth 60-day rollover (bound by the 12-month limitation)."

No, the deposit into the Roth IRA of the $9,600 withheld for taxes from the traditional IRA distribution is still a Roth conversion, no rollover frequency limitation involved. The fact that cash is distributed from the traditional IRA (effectively to you in the form of tax withholding credited to you) and you subsequently deposit an equal amount of cash into a Roth IRA does not change the nature of the transaction from being a Roth conversion. It is neither a rollover from a traditional IRA to a traditional IRA nor a rollover from a Roth IRA to a Roth IRA which are the only types of rollovers that involve this limitation.

If you rolled over to a traditional IRA any of the $9,600 withheld for taxes, that would involve the limitation since it would be traditional IRA to traditional IRA.

Section 408A(e) of the tax code includes:

For purposes of section 408(d)(3)(B), there shall be disregarded any qualified rollover contribution from an individual retirement plan (other than a Roth IRA) to a Roth IRA.

Section 408(d)(3)(b) is the rollover frequency limitation. A "qualified rollover contribution from an individual retirement plan (other than a Roth IRA) to a Roth IRA" is the definition of a Roth conversion.
