If you only do five things in 2026: a priority checklist, ranked by financial stakes

The adult-child checklist covers everything worth having in place, in roughly the order most families encounter it. This is a different kind of list — not everything, just the handful of items where getting it wrong, or simply getting to it too late, carries the highest financial cost. If your time or your parent’s attention is limited, start here.

The ranking below isn’t about which topic is most uncomfortable to raise. It’s about dollar exposure and reversibility — how much money is realistically at stake, and how much of that exposure is permanent once a deadline or a health event has passed.

1. Long-term care funding — the largest, least-reversible gap

Roughly 70% of people turning 65 will need some form of long-term care, and roughly 80% have no financial plan for it. This is the single largest dollar figure on this list by a wide margin — care can run well into six figures, and once a health event arrives, the options for funding it (insurance underwriting, Medicaid planning) narrow sharply or close outright. There’s no comparable penalty elsewhere on this list for waiting; this is the one where the cost of delay compounds the most.

Why now specifically: 2026 is the year the oldest Baby Boomers turn 80 — the age at which long-term care needs typically become real rather than hypothetical, at the leading edge of a wave that will keep building for the next decade (Brookings). See the cost nobody plans for and why finding care is getting harder — the second is about availability, not just cost, and it’s a real factor in how soon to act.

2. Power of attorney — the gap that creates its own, separate cost

Without a financial power of attorney in place before incapacity, the alternative isn’t “nothing happens” — it’s a court-supervised guardianship or conservatorship, which has its own direct cost on top of whatever care or financial need triggered it. Establishing one typically runs $3,000–$10,000 in routine cases, and can climb past $25,000 if any family member contests it (LawVex). A document that usually costs a few hundred dollars to set up in advance is replaced, after incapacity, by a process that costs ten to a hundred times more — and the only way to avoid it is to have it signed before it’s needed, since a parent can no longer legally execute one once they’ve lost capacity.

See power of attorney for a parent for what to actually set up.

3. Medicare enrollment timing — the only permanent penalty on this list

Most items here cost money if delayed. This one is structured as a literal, lifelong penalty: missing the Part B enrollment window adds 10% to the monthly premium for every full 12-month period of delay, for as long as the person has Part B — not a one-time fee, a permanent surcharge (Medicare.gov). Part D carries a similar permanent penalty structure. Unlike LTC funding or POA, this has a hard, specific deadline tied to a birthday or a loss of employer coverage — worth confirming explicitly rather than assuming a parent has it handled.

4. Medicaid planning timing — the deadline that’s already running whether or not you’ve started

If Medicaid is likely to be part of how long-term care eventually gets funded, the relevant planning has a five-year look-back period: asset transfers made within five years of applying can trigger a penalty period of ineligibility. The clock starts from the transfer date, not from when a need becomes obvious — which means the cost of waiting to start this conversation is measured in years, not the weeks or months that most other items on this list allow for (Medicaid.gov). This is elder-law-attorney territory, not a DIY decision — but the timing constraint is worth understanding even before that conversation happens.

5. Housing equity — the largest asset most families haven’t actively decided about

For most retirees, home equity is the single largest asset on the balance sheet, and “we haven’t really discussed it” is a more expensive default than it looks. Whether a parent stays, downsizes, or relocates changes the timeline for funding everything above it on this list — equity that’s tied up in a home can’t pay for care without a deliberate decision to access it, whether through sale, downsizing, or a home equity option.

See stay, downsize, or move for the framework.

What this list deliberately leaves out

This isn’t the full picture — it’s the five items where the dollar stakes and the cost of delay are highest. Conversations about wishes, social connection, caregiver burnout, and family coordination matter just as much to how this goes, but they don’t carry the same kind of hard, often irreversible financial deadline. The full checklist covers all of it; this is the subset worth tackling first if time is genuinely limited.
