Next job, different axis: take it with you and make it repeat — export this dated checklist as a .csv for the client file, and set Chrome alarms that fire ahead of each date. $60 once · one licence key per person or team seat · Form 706 prep starts near $2,500, estate CPAs bill $150-$400/hr, and the IRS closing letter is a $56 Pay.gov fee (T.D. 10031).
Exclusion locked to the year of death Applies the IRC 2010(c)(3) basic exclusion for the decedent's year of death - $15,000,000 for 2026 under OBBBA section 70106 and Rev. Proc. 2025-32, $13,990,000 for 2025 - instead of the repealed sunset figure that pre-2025 sources still quote.
Nine-month due date and the Form 4768 extension Counts the IRC 6075(a) nine-month Form 706 due date from the date of death and, when the automatic Form 4768 extension is elected, the six-month extended date, then shows days remaining from today.
Earliest closing-letter request date The IRS asks requesters to wait at least nine months after Form 706 is filed before ordering Letter 627 on Pay.gov; this dates that window from the actual filing date so nobody pays the user fee early.
Five-year late portability election window When the gross estate is under the filing threshold, Rev. Proc. 2022-32 allows a late DSUE portability election up to the fifth anniversary of death; the tool dates that anniversary and says when it does not apply.
Month-one cost of slipping the date Prices the IRC 6651(a)(1) failure-to-file addition - five percent of the tax for each month or fraction of a month - so the deadline has a dollar figure next to it, not just a date.
CSV checklist export and deadline alarms The paid layer writes the dated checklist to a .csv you can drop in the client file and sets Chrome alarms ahead of each date, so the clock keeps running after the tab is closed.
