I'm looking to retire this November. I plan to take an NUA distribution from my 401K in December with like-kind transfer of 401K company stock to company stock in a brokerage account (no stock sales). I'm already making estimated tax payments for 2024. The NUA cost-basis will more than double my income for 2024. I plan to hold the stock for at least a year before any is sold from the brokerage account.
Can I pay the increase in taxes due to the NUA in my final quarter estimated tax payment and not spread the increase over the entire year? How do I reflect that in the required forms? Is the one-large-quarter estimated tax covered by IRS Form 4972? If so, I don't see how that works.
I'm interested in getting TurboTax Live for the upcoming year, tax year 2024, to handle the unusual situations I'll be in, but I don't see where to get that info - either I can't find it or the website isn't working for me.
