What is retirement income planning? It is the ongoing process of coordinating every retirement income source (Social Security, pensions, account withdrawals, Roth, and taxable savings) so each one is drawn in a tax aware order.
Key Takeaways
- Retirement income usually comes from six buckets: Social Security, pensions, pre-tax 401(k)/IRA withdrawals, Roth accounts, taxable brokerage or bank savings, and annuities. Each is taxed differently.
- Up to 85% of Social Security benefits can be included in taxable income once combined income passes the thresholds set by the Social Security Administration.
- Required minimum distributions begin at age 73 for people born 1951 to 1959 and age 75 for those born in 1960 or later, per IRS RMD guidance.
- A missed RMD carries a 25% excise tax, reduced to 10% if corrected within two years (IRS).
- For 2026 the 24% federal bracket tops out at $201,775 (single) and $403,550 (married filing jointly), and the standard deduction is $16,100 and $32,200 (IRS, 2026).
- Withdrawal sequencing and Roth conversions are the levers that decide how much of retirement income is taxed, and when.

What are the main sources of retirement income?
Most retirees draw from six income sources, and each is taxed on its own rules. Knowing which bucket a dollar comes from is the first step in retirement income planning, because two retirees with the same spending can owe very different taxes depending on where they pull from.

The common sources are Social Security, employer or government pensions, pre-tax retirement accounts such as a traditional 401(k) or IRA, Roth accounts, taxable brokerage and bank savings, and annuities. Q3 Advisors covers the full list in this overview of the types of retirement income, and the underlying account structures in this guide to the types of retirement accounts.
A useful way to organize them is by tax treatment rather than by dollar amount. That reframing is what turns a pile of statements into a plan.
How is each source of retirement income taxed?
Each retirement income source falls into one of three tax treatments: taxed as ordinary income, partially taxed, or tax free. The table below maps the common sources to how the IRS generally treats them.
| Income source | General federal tax treatment | Tax bucket |
|---|---|---|
| Social Security | 0%, up to 50%, or up to 85% of benefits taxable based on combined income | Partially taxed |
| Pension income | Generally taxed as ordinary income | Tax deferred |
| Traditional 401(k) and IRA withdrawals | Taxed as ordinary income; subject to RMDs | Tax deferred |
| Roth IRA and Roth 401(k) | Qualified withdrawals are tax free | Tax free |
| Taxable brokerage and bank savings | Interest and dividends taxed yearly; long term gains at capital gains rates | Taxable |
| Annuities | Earnings portion taxed as ordinary income; return of principal not taxed | Mixed |
Traditional and Roth treatment sit at opposite ends. The IRS Roth comparison chart puts it plainly: pre-tax contributions are made with before-tax dollars and taxed on withdrawal, while qualified Roth withdrawals are not taxed at all. Q3 Advisors maintains a deeper reference on tax free retirement income sources for readers who want the full list.
What are the three tax buckets in retirement income planning?
The three tax buckets are tax deferred, tax free, and taxable, and a durable retirement income plan usually holds money in all three. Spreading assets across buckets gives a retiree choices about which dollar to spend in any given year.
Tax deferred money (traditional 401(k) and IRA balances) is taxed as ordinary income when withdrawn. Tax free money (Roth accounts and, when qualified, health savings account dollars) comes out untaxed. Taxable accounts sit in the middle, with their own capital gains and dividend rules.
Because each bucket behaves differently, the mix matters more than the total. Retirees with most of their savings in one bucket often have fewer options, which is one reason the retirement bucket strategy and Roth planning get so much attention.
How does withdrawal sequencing work in retirement income planning?
Withdrawal sequencing is the order in which a retiree taps each account, and that order changes the lifetime tax bill. A conventional default is to spend taxable accounts first, then tax deferred, then Roth last, so tax free money keeps compounding.
That default is a starting point, not a rule. In low income years, some retirees instead fill up the lower brackets with traditional withdrawals or conversions on purpose, rather than leaving those brackets unused. A financial professional can model which order fits a specific situation.
Q3 Advisors walks through the mechanics in its guides to a tax efficient withdrawal strategy and the guardrails withdrawal strategy, which adjusts spending as markets move. The timing of Social Security fits here too, since delaying benefits can open low bracket years earlier in retirement, as covered in when to take Social Security.
How do required minimum distributions affect retirement income planning?
Required minimum distributions force taxable withdrawals from pre-tax accounts starting at age 73 or 75, and they can push a retiree into a higher bracket. According to the IRS, the first RMD can be delayed until April 1 of the year after the account owner reaches RMD age, with later RMDs due by December 31.
The stakes are real. A missed RMD is subject to a 25% excise tax on the shortfall, reduced to 10% if corrected within two years. Roth IRAs are different: the IRS confirms they carry no required minimum distributions during the owner’s lifetime, which is part of why Roth balances add flexibility late in retirement.
Large pre-tax balances that have never been touched can create outsized RMDs a decade later. Q3 Advisors keeps a current explainer on required minimum distributions in 2026 with the age rules and deadlines.
Where do Roth conversions fit in a retirement income plan?
Roth conversions move money from a tax deferred account into a tax free account, and paying tax on that money now can lower the taxable balance that later drives RMDs and Social Security taxation. The trade is a bigger tax bill today in exchange for more tax free income later.
Conversions tend to draw the most interest in the window between retirement and the start of RMDs, when income (and often the marginal bracket) is temporarily lower. Filling up a low bracket, for example the 24% bracket that runs to $201,775 single or $403,550 married filing jointly in 2026, is one framework a professional can model. It is not automatically right for everyone.
Because Q3 Advisors specializes in this area, it maintains a foundational explainer on what a Roth conversion is and a strategy guide on optimizing retirement income with Roth conversions. The point is not to convert as much as possible, but to fit conversions into the wider sequencing plan.
How do taxes on Social Security change the plan?
Social Security is only partially taxed, and how much depends on combined income rather than a flat rate. The Social Security Administration uses combined income (adjusted gross income, plus nontaxable interest, plus half of benefits) to decide whether 0%, up to 50%, or up to 85% of benefits enter taxable income.
| Filing status | Combined income | Portion of benefits that may be taxable |
|---|---|---|
| Single | Below $25,000 | 0% |
| Single | $25,000 to $34,000 | Up to 50% |
| Single | Above $34,000 | Up to 85% |
| Married filing jointly | Below $32,000 | 0% |
| Married filing jointly | $32,000 to $44,000 | Up to 50% |
| Married filing jointly | Above $44,000 | Up to 85% |
This is why the order of withdrawals interacts with Social Security. Pulling a large traditional withdrawal in the same year benefits are received can raise combined income and, in turn, the taxable share of the benefit. State rules add another layer, which Q3 Advisors tracks in its guide to states that do not tax retirement income in 2026.
Where should retirement income planning go next?
Retirement income planning at the overview level answers three questions: where the money comes from, how each source is taxed, and in what order to use it. The deeper decisions (sequencing, Social Security timing, and Roth conversions) each deserve their own analysis.
A practical next step is to inventory every account by tax bucket, estimate future RMDs, and map how Social Security taxation and bracket thresholds interact across a multi year window. From there, the deep dives on withdrawal order and Roth conversion timing turn the overview into a specific plan a professional can pressure test.

Frequently asked questions about retirement income planning
What is the goal of retirement income planning?
The goal is to convert savings and benefits into a reliable, tax aware income stream. That means coordinating Social Security, pensions, account withdrawals, and taxable savings so the household draws each dollar from the source that keeps the lifetime tax bill reasonable, rather than pulling at random.
In what order should retirement accounts be withdrawn?
A common default is taxable accounts first, then tax deferred, then Roth last, so tax free money compounds longest. That order is a starting point only. In low income years some retirees intentionally take traditional withdrawals or Roth conversions to use up lower brackets, so a professional often models the sequence.
At what age do required minimum distributions start in 2026?
Per the IRS, RMDs begin at age 73 for people born between 1951 and 1959, and at age 75 for those born in 1960 or later. The first distribution can be delayed until April 1 of the year after reaching RMD age, with subsequent RMDs due by December 31 each year.
How much of Social Security is taxable?
Depending on combined income, 0%, up to 50%, or up to 85% of benefits can be included in taxable income. For single filers the thresholds are $25,000 and $34,000, and for married couples filing jointly they are $32,000 and $44,000, according to the Social Security Administration.
What are the three tax buckets in retirement?
They are tax deferred (traditional 401(k) and IRA), tax free (Roth accounts and qualified HSA dollars), and taxable (brokerage and bank savings). Holding money across all three gives a retiree flexibility to choose which type of dollar to spend in any given year.
Where do Roth conversions fit in retirement income planning?
A Roth conversion moves money from a tax deferred account to a tax free one, paying tax now to reduce future taxable balances that drive RMDs and Social Security taxation. Conversions are often modeled in lower income years between retirement and the start of RMDs, but they are not right for every situation.
Does the order of withdrawals affect taxes on Social Security?
Yes. Because Social Security taxation is based on combined income, a large traditional withdrawal in the same year benefits are received can raise combined income and increase the taxable share of the benefit. Sequencing withdrawals with that interaction in mind is a core part of the plan.
