The dates that cannot be fixed later
Dated deadlines are the statute edges on your calendar: conversion cutoffs, Medicare windows, RMD due dates, and claim months. Ivory Plains prints the ones that belong to your year. You act on them yourself. Support is support@ivoryplains.com. No discovery call. No AUM.

How each deadline is dated on your plan
Send birth years and benefit estimates after checkout. The tabs walk each hard date: enrollment window, lookback years, December conversion cutoffs, and the first distribution trap including whether an April 1 delay helps or stacks two RMDs into one tax year.
Initial enrollment: the seven-month window
Miss the Medicare initial enrollment window and the fix is not a phone call in April. General enrollment runs January through March, coverage is delayed, and late-enrollment penalties can follow when you lacked qualifying coverage.
The initial enrollment period usually begins three months before the month you turn 65 and ends three months after that month. That is seven months on the calendar, which sounds long until travel, paperwork, and employer-coverage decisions compress it. If you have creditable coverage through an employer plan, delay rules can differ. If you do not, the window is the date that matters.
Ivory Plains prints your birth month, the first and last day of the initial window, and whether employer coverage appears to support a delay under the facts you provided. It does not enroll you. It does not talk to Social Security or Medicare on your behalf. It puts the dates next to your claim and conversion calendar so you do not treat health coverage as a separate project that can wait until after tax season.
Part D and Medigap decisions have their own timing. The plan flags the years those choices typically arise and points you to the government and insurer channels where enrollment actually happens. The ledger line is the deadline. The action is yours.
Ivory Plains prints the dates that belong to your year, not a generic checklist. If a window closes this year, the plan names the month. If it opens next year, the plan says so in writing.
You act on the dates yourself: file Medicare, request RMDs, instruct conversions. Support is support@ivoryplains.com when a printed date needs a clarifying note. There is no discovery call and no AUM relationship.
Medicare Initial Enrollment and IRMAA lookbacks are calendar facts, not soft reminders. Missing a window can mean delayed coverage or a surcharge year you cannot unwind with a phone call in spring.
The dated plan lists which windows apply to your household this year and which wait. You enroll and appeal on your own; Ivory Plains does not enroll you.
Lookback map: income year to premium year
- Income year T. Wages, conversions, capital gains, and other MAGI items land on the return you file the following spring.
- Premium year T+2. Medicare uses that MAGI to set IRMAA tiers for Part B and Part D. A conversion you celebrate in December can appear on a premium notice two winters later.
- Joint vs single thresholds. Filing status on the lookback return controls which tier table applies. Household plans use the status you will actually file.
- Life-changing event appeals. Work stoppage, marriage, divorce, and similar events can support an IRMAA appeal. The plan notes when your facts may qualify; you file the appeal with Medicare.
The deadline here is not a single day. It is the recognition that authorizations you make this year have a dated premium consequence later. Ivory Plains pairs each scheduled conversion and large taxable event with the premium year it will influence so the cost is visible before you instruct the custodian.
You still decide whether the Roth or gain is worth the premium step. The ledger's job is to stop the surprise.
December 31: the conversion cutoff
- Instruct-by date. The last business day the plan treats as safe to submit a conversion request given your custodian's stated processing times and the holiday calendar.
- Settlement date. The day the conversion must post to count for the tax year. For calendar-year conversions that day is December 31 of the listed year.
- Estimated tax checkpoints. If the conversion creates a large balance due, mid-year payment dates sit on the same ledger so April is not the first time you learn the cost.
- Employer-plan lag. In-plan Roth conversions and plan-to-IRA moves can require forms and waiting periods. Those lags are dated when your facts include a workplace account.
December 31 is absolute for the tax year of a Roth conversion. There is no January fix that moves a late settlement back into December. Ivory Plains therefore dates the instruct-by day weeks earlier than New Year's Eve and prints it beside the conversion amount for that year.
You submit the request to the firm that holds the account. If the firm misses the settlement window after a timely instruction, that dispute is between you and the custodian. The plan's ledger exists so timely has a printed meaning before the week of Christmas.
December 31 is a hard edge for Roth conversions and many year-end moves. January cannot reopen a conversion you meant to finish in the prior tax year. The plan sequences December work so the cutoff is visible weeks ahead.
Fees stay published: Plan $1,200 once; Plan and year $1,200 plus $95 per month or $950 per year prepaid; Household $3,400 per year. You file and instruct on your own accounts.
First RMD year: December 31 or April 1
Your first required minimum distribution has a special timing choice under current law. You generally may take it by December 31 of the year you reach the applicable RMD age, or you may delay that first distribution until April 1 of the following calendar year. The delay can feel helpful if you want another quarter of tax deferral. It can also force two full RMDs into a single tax year: the delayed first RMD by April 1 and the second RMD by December 31 of that same year.
Two RMDs in one year raise ordinary income, can push federal brackets, can increase the share of Social Security that is taxable, and can tip IRMAA two years later. For some households the April 1 option is still correct. For many, taking the first RMD by December 31 of the age-attaining year avoids the stack. Ivory Plains prints both paths with the dollar and premium consequences beside them, then recommends one dated action.
After the first year, each RMD is due by December 31 of that distribution year. The plan shows the account subject to the RMD and whether a qualified charitable distribution is relevant to your facts. It does not withdraw the funds.
- Confirm the applicable RMD age under current law for your birth year.
- Compare December 31 first-year timing with the April 1 delay.
- If delay is chosen, model two RMDs in the following tax year.
- Print the chosen deadline on the same ledger as conversions and Medicare dates.
Required minimum distributions, QCDs, and employer-plan timing sit on the same calendar as claiming and conversions. The plan does not treat them as a separate product upsell.
When a date moves because statute changed after your plan date, email support@ivoryplains.com with the plan date printed on your PDF. Updates follow the Plan and year or Household engagement you already have.
Dated deadlines in depth
Hard dates versus soft reminders: December 31 conversions, Medicare enrollment windows, RMD due dates, and claim months are statutes or agency calendars. Ivory Plains puts your year on them. Soft marketing reminders are not the product.
Miss December 31 and January cannot fix a conversion. Miss the Medicare window and general enrollment is January through March with delayed coverage. Miss an RMD and the excise tax starts at 25 percent under current law. The plan exists so those edges are visible before they arrive.
Why the dates matter
What the deadlines show
Your enrollment window, first distribution year, and December 31 cutoffs with your dates on them.
Dates you can act on
Each deadline carries your date, so the calendar is specific rather than a generic rule list.
Fast Automation
Replace manual steps, brittle cron jobs, and custom glue code with stable, predictable automation that runs the same way every time.
Medicare and lookback
Enrollment windows, surcharge lookback years, and conversion cutoffs that cannot be fixed in January.
How to use the deadline ledger
Read the ledger with your birthdays and tax years visible. Circle instruct-by dates weeks before December 31. Circle Medicare window open and close dates from your birth month. Circle the first RMD year from your birth year under current law.
Then act in the channels that move the money: SSA, Medicare, and your custodian. Ivory Plains dates the work. You still do the work. Fees stay published. Support is support@ivoryplains.com.
Extended field guide: dated deadlines as the enforcement layer
Every other Ivory Plains page can be right on paper and still fail if the calendar is missed. Dated deadlines translate claim months, conversion years, and withdrawal phases into actions with due dates: SSA filing lead time, Medicare enrollment windows, custodian conversion cutoffs, estimated tax dates, and workplace distribution request timing. This guide explains how to use that calendar, what breaks when you miss it, how to recover without compounding the error, and how updates work when life moves a date.
How this page connects to the rest of the ledger
The deadlines page only works when the peer pages stay true. Ivory Plains delivers a dated system: claim months, conversion dollars by year, withdrawal sources by phase, and calendar deadlines. Changing one page in your head without rebuilding the others creates a plan that looks complete and fails in December.
It is the enforcement layer for claiming, conversions, and withdrawals. If a conversion year exists on one page and no custodian cutoff exists here, the year is ornamental. If a claim month exists without SSA lead time, the bridge funding on the withdrawal page will be wrong in the first benefit month.
- Claiming decisions set when Social Security income begins and when delayed credits stop
- Conversion windows set how much ordinary income room each tax year still has
- Withdrawal order sets which account funds spending without wrecking those years
- Dated deadlines set the external clocks at SSA, Medicare, custodians, and the IRS
Whose clock is ticking
Social Security, Medicare, custodians, employers, and the IRS do not read your plan PDF. They enforce their own clocks. The deadlines page is the bridge. If it says to submit a conversion instruction by a December date, that is because settlement risk can push the taxable event into January. If it shows an SSA filing lead before a claim month, that is because benefits do not start because you thought about them. If it flags a Medicare Initial Enrollment Period, that is because delayed Part B without creditable coverage can mean lifelong late penalties.
- SSA and Medicare clocks are statutory
- Custodian clocks are operational and vary by firm
- Tax payment clocks are federal and state
- Employer coverage end dates are contractual and easy to miss
- Plan administrator clocks for pensions and deferred comp are their own bureaucracy
Worked examples of misses
Miss A: conversion intended for one tax year initiated on December 30 that settles in January. The conversion window for the intended year is unused. The next year’s window may already be full because a claim starts. You cannot explain it to the IRS with a screenshot of your intent.
Miss B: claim recommended for June, filing started in June, first payment months later, bridge cash runs short in July because withdrawals were scheduled assuming an earlier deposit. The claim math was fine. The funding calendar was ignored.
Miss C: still working past 65 with employer coverage, then retiring mid-year without tracking the Special Enrollment Period. Part B delay creates penalties and coverage gaps the plan’s healthcare assumptions did not include because you did not update the stop-work date.
Miss D: estimated taxes ignored after a large conversion year. April brings a balance due and underpayment penalties. The household then raids an IRA for cash, filling the next conversion year with unplanned income. One missed payment becomes two years of damage.
- Map each plan action to an external institution
- Apply that institution’s cutoff and processing time
- Print a date you can put on a checklist
- Build a small buffer before hard cutoffs where settlement risk exists
- Rebuild when job, claim, or account structure changes
- Confirm state payment calendars if you owe state estimates
Input quality for deadlines
Deadlines are only as good as the dates underneath them. Wrong birth dates move Medicare windows. Wrong stop-work months move employer coverage ends. Wrong custodian names do not change the tax year rules but do change how early you must instruct. If you switch from one brokerage to another after delivery, processing times change. Tell the file. Do not assume the old checklist still applies.
State estimated taxes, local tax withholding on retirement distributions, and pension administrator calendars are easy to omit. If they apply to you, they belong in the questionnaire or an update note. Ivory Plains will not call your payroll department to ask.
Travel months, surgery schedules, and busy seasons at work are not statutes, but they are why buffers exist. If you know December is impossible for paperwork in your household, say so before delivery so instructions can be front-loaded. Silence produces a precise date you will miss.
What to do when you miss a date
First, stop compounding the miss. Do not double a conversion the next week without checking the new year’s income. Do not claim earlier than recommended just because you are angry at a custodian delay. Second, compare the miss against the plan’s remaining years. Some misses are recoverable with a rebuild. Some permanently use a bracket year. Third, on Plan and year or Household, correct inputs and regenerate. On Plan at $1,200 once, accept that a single delivery cannot chase every later miss without a new purchase or upgrade.
A missed deadline turns a precise plan into an approximate one. Approximate plans recreate the discovery-call industry Ivory Plains is built to avoid.
Edge cases
International travel during enrollment windows, incapacity without powers of attorney ready, custodian ACATS transfers mid-conversion season, and employer stock sale blackout periods all create calendar traps. If any of these are plausible, put them in the file early. Support at support@ivoryplains.com can help you read how a printed deadline maps to your situation. It cannot file for you.
Death of a spouse resets claim options, account titles, and often Medicare and employer coverage. The deadlines page from the married plan is not a grief checklist. Rebuild.
Tiers and calendar maintenance
Annual update tiers exist partly because calendars change when claims, jobs, and account locations change. Plan is a snapshot. Plan and year and Household keep the snapshot from becoming folklore. Fees stay public: Plan $1,200 once; Plan and year $1,200 then $95 a month or $950 a year prepaid; Household $3,400 a year. There is no AUM fee and no mandatory discovery call. You file and instruct yourself. Questions about reading a page go to support@ivoryplains.com.
Building a personal checklist from the page
Copy the dated deadlines into whatever system you actually open weekly. A PDF that lives in a downloads folder is not a calendar. Add reminders thirty days and seven days before each hard cutoff. Include the institution name and the exact action: file on ssa.gov, instruct custodian X to convert Y dollars, request workplace distribution, pay estimated tax. Vague reminders recreate vague plans.
When two deadlines collide in the same week, sequence them. Custodian conversions often need earlier action than an SSA click. Estimated taxes may need cash raised from brokerage first, which means the withdrawal order’s trade happens before the IRS payment date. The deadlines page lists dates; your checklist adds the dependency order.
