A retirement planning checklist works best when it is organized by time, because the decisions that matter a decade out are not the ones that matter in the final months.
Key Takeaways
- Required minimum distributions begin at age 73 for anyone born 1951 to 1959 and age 75 for anyone born in 1960 or later, under SECURE 2.0 (IRS).
- The Medicare Initial Enrollment Period lasts 7 months: the three months before your 65th birthday month, that month, and the three months after (Medicare.gov).
- Full retirement age is 67 for everyone born in 1960 or later; claiming at 62 reduces the monthly benefit by 30 percent, and each year of delay past full retirement age adds about 8 percent up to age 70 (SSA.gov).
- In 2026 the elective deferral limit for a 401(k), 403(b), 457, or TSP is $24,500, with an $8,000 catch-up at 50-plus and $11,250 for ages 60 to 63 (IRS).
- The gap years between leaving work and the first RMD are often the lowest-bracket years a household will see, which is why many retirees study a Roth conversion during that window.
- Up to 85 percent of Social Security benefits can be taxable once combined income passes $34,000 (single) or $44,000 (married filing jointly), thresholds fixed in law and not indexed (SSA).

What is a retirement planning checklist?
A retirement planning checklist is a time-phased list of decisions and tasks, grouped by how many years remain before you stop working. Rather than a single to-do list, it separates the actions that compound over a decade from the ones that only make sense in the final year or two.
This page is the actionable, step-by-step version. For the concepts behind how the pieces fit together, the conceptual companion is Q3 Advisors’ guide to retirement income planning, which explains the framework this checklist puts into motion. The phases below run from more than a decade out through the first years of retirement.
| Phase | Primary focus | Signature tasks |
|---|---|---|
| More than 10 years out | Accumulation and account mix | Max tax-advantaged savings, diversify account types, estimate future spending |
| About 5 years out | Design and stress-test | Firm up spending, map tax buckets, draft Social Security and Medicare timing |
| 1 to 2 years out | Logistics and enrollment | Confirm Medicare window, finalize claiming age, set the withdrawal sequence |
| At retirement and beyond | Execution and tax control | Begin withdrawals, use the gap years, prepare for RMDs at 73 or 75 |
Phase 1: More than 10 years out
With a decade or more remaining, the highest-leverage work is building a large and diversified base of savings. Small changes to savings rate and account mix have years to compound, and there is time to recover from market volatility.
- Estimate future spending. Sketch a rough annual budget for retirement in today’s dollars. A first pass is enough at this stage; it gets refined later.
- Maximize tax-advantaged savings. In 2026 the elective deferral limit for a 401(k), 403(b), 457, or TSP is $24,500, and the IRA limit is $7,500, per the IRS contribution limit tables. Capturing any employer match first is a common starting point.
- Diversify across tax treatments. Holding a mix of pre-tax, Roth, and taxable accounts creates flexibility later. Q3 Advisors’ overview of the types of retirement accounts explains how each bucket is taxed.
- Build an emergency reserve. A cash cushion keeps early setbacks from forcing withdrawals or debt.
- Review beneficiaries. Confirm the named beneficiaries on every retirement account, since those designations override a will.
Phase 2: The five-year runway
Around five years out, the plan shifts from accumulating to designing. This is when a rough estimate becomes a tested spending figure and the tax picture comes into focus.
- Firm up the spending estimate. Replace the rough budget with detail: housing, healthcare, travel, and one-time costs. Separate essential from discretionary spending.
- Map the tax buckets. Total the balances in pre-tax, Roth, and taxable accounts. This map drives later sequencing decisions; the tax-efficient withdrawal strategy guide walks through how the buckets interact.
- Draft Social Security timing. Model claiming at 62, at full retirement age, and at 70. Q3 Advisors covers the tradeoffs in when to take Social Security.
- Preview healthcare and Medicare. If retiring before 65, price the coverage bridge. Note the Medicare enrollment window described below.
- Increase catch-up contributions. Savers age 50-plus can add $8,000 to a workplace plan in 2026, and those ages 60 to 63 can add $11,250 (IRS).
Phase 3: One to two years before retirement
Inside two years, the work turns to logistics and irreversible enrollment decisions. Deadlines around Medicare and Social Security become concrete, so precision matters.
- Confirm the Medicare window. The Initial Enrollment Period is the 7 months around your 65th birthday, per Medicare.gov. Missing it can trigger lifelong late-enrollment penalties.
- Finalize the claiming age. Full retirement age is 67 for anyone born in 1960 or later, and delaying past it adds delayed retirement credits up to age 70, per the Social Security Administration.
- Set the withdrawal sequence. Decide which accounts to draw from first, second, and last (covered in the sequence section below).
- Update estate documents. Review the will, powers of attorney, healthcare directive, and any trust, alongside account beneficiaries.
- Plan the gap-year strategy. Identify the low-income years after work stops but before benefits and RMDs begin, and decide whether a partial Roth conversion fits.
Phase 4: At retirement and the first years
At retirement, the plan moves from paper to practice. The first years are also when tax-planning opportunities are widest, because earned income has stopped but required distributions have not started.
- Turn on the income plan. Begin withdrawals in the planned order and set up any recurring transfers.
- Manage the tax bracket each year. Watch taxable income against bracket thresholds; in 2026 the 24 percent bracket tops out at $201,775 (single) and $403,550 (married filing jointly), per the IRS.
- Use the gap years deliberately. These low-bracket years are the planning window discussed next.
- Track Social Security taxation. Coordinate withdrawals with the combined-income thresholds that determine how much of the benefit is taxable.
- Prepare for RMDs. Know your first RMD year (age 73 or 75) well ahead of time so distributions do not arrive as a surprise.
Why are the gap years the Roth conversion window?
The gap years are the stretch between the end of a paycheck and the start of required minimum distributions, and they are often a household’s lowest-income years. With wages gone and RMDs not yet due, taxable income can dip into a lower bracket, which is exactly the condition that makes a conversion worth studying.
A Roth conversion moves money from a pre-tax account to a Roth account and creates taxable income in the year it happens, as the IRS explains in its rollover and conversion FAQs. Filling a lower bracket during the gap years, rather than a higher one later once RMDs begin, is the reasoning behind the strategy. Q3 Advisors details the mechanics in what is a Roth conversion. Retirees in a low-bracket year often consider whether converting part of a pre-tax balance fits their situation, and a financial professional can model whether the timing and amount make sense before any conversion is made.
How do RMD ages 73 and 75 change the plan?
Required minimum distributions force taxable withdrawals from pre-tax accounts starting at age 73 or 75, which can push income and Medicare costs higher if not planned for. Under SECURE 2.0, the starting age is 73 for those born 1951 to 1959 and 75 for those born in 1960 or later, according to the IRS required minimum distribution FAQs.
Because RMDs are calculated on the full pre-tax balance, a large untouched pre-tax account can generate sizable required income later. That is one reason the gap-year checklist items above focus on drawing down or converting pre-tax dollars earlier. Q3 Advisors keeps the current rules in required minimum distributions 2026.
When should Social Security and Medicare start?
Social Security can start as early as 62 and as late as 70, while Medicare centers on age 65. The two decisions are separate, and they carry different deadlines and tradeoffs.
| Decision point | Rule | Source |
|---|---|---|
| Earliest Social Security | Age 62, with a roughly 30 percent reduction versus full retirement age for those born 1960 or later | SSA |
| Full retirement age | Age 67 for anyone born in 1960 or later | SSA |
| Delayed credits | About 8 percent added per year of delay, up to age 70 | SSA |
| Medicare enrollment | 7-month Initial Enrollment Period around the 65th birthday | Medicare.gov |
Claiming timing also interacts with taxes. Up to 85 percent of benefits can be taxable once combined income rises above the top thresholds, per the Social Security Administration, which is why the checklist coordinates claiming with the withdrawal plan rather than treating them separately.
How do you build a withdrawal sequence?
A withdrawal sequence is the order in which you spend from taxable, tax-deferred, and Roth accounts. A common default draws from taxable accounts first, tax-deferred next, and Roth last, but the gap years and RMD rules can justify blending them.
The point of sequencing is to smooth taxable income across retirement rather than letting it spike in RMD years. Q3 Advisors’ tax-efficient withdrawal strategy guide covers how the buckets combine. Households retiring before 59 and a half sometimes need penalty-free access to pre-tax funds; the options are outlined in the secret way to access retirement funds early. A financial professional can help sequence withdrawals around your specific bracket and RMD timeline.
Frequently asked questions
How many years before retirement should I start a checklist?
Starting more than a decade out gives the accumulation steps the most time to compound, but the phased approach means there are useful actions at every stage, including the final one to two years when Medicare and Social Security deadlines apply.
At what age do required minimum distributions start?
Required minimum distributions begin at age 73 for people born between 1951 and 1959 and at age 75 for people born in 1960 or later, under SECURE 2.0, according to the IRS.
When is the Medicare enrollment window?
The Initial Enrollment Period spans 7 months: the three months before your 65th birthday month, the birthday month itself, and the three months after, per Medicare.gov. Missing it can lead to lifelong late-enrollment penalties.
What is full retirement age for Social Security?
Full retirement age is 67 for anyone born in 1960 or later. Claiming at 62 reduces the monthly benefit by about 30 percent, and delaying past full retirement age adds roughly 8 percent per year up to age 70, per the Social Security Administration.
What are the gap years in retirement planning?
The gap years are the period after work stops but before Social Security and required minimum distributions begin. Because income is often at its lowest then, many retirees study whether a partial Roth conversion fits before RMDs raise their taxable income.
How much can I contribute to a 401(k) in 2026?
The 2026 elective deferral limit is $24,500. Savers age 50-plus can add an $8,000 catch-up, and those ages 60 to 63 can add $11,250, according to the IRS.
How is a retirement planning checklist different from a retirement income plan?
The checklist is the phased set of actions to take; the retirement income plan is the underlying framework for turning savings into sustainable income. The two work together, and Q3 Advisors covers the framework in its retirement income planning guide.
