The main types of retirement income fall into eight sources that most retirees draw from: Social Security, pensions, Traditional 401(k) and IRA withdrawals, Roth withdrawals, annuities, taxable brokerage income, part-time work, and rental income. What separates a comfortable retirement from a taxed-away one is not just how many sources you have, but how each source is taxed and how you blend them.
The main types of retirement income are Social Security, pensions, Traditional 401(k) and IRA withdrawals, Roth withdrawals, annuities, taxable brokerage income (dividends, interest, capital gains), part-time work, and rental income. Each falls into one of three tax buckets: taxable, tax-deferred, or tax-free. Knowing which bucket a dollar comes from is how you control your retirement tax bill.
What are the main types of retirement income?
The main types of retirement income are Social Security, pensions, Traditional 401(k) and IRA withdrawals, Roth IRA and Roth 401(k) withdrawals, annuities, taxable brokerage income, part-time work, and rental income. A Health Savings Account (HSA) can act as a ninth source. Every dollar you receive sits in one of three tax buckets, and that bucket decides the rate.

The three-bucket model is the organizing spine of a tax-aware retirement plan:
- Taxable bucket: money taxed as you earn or realize it, such as brokerage dividends, interest, capital gains, part-time wages, and rental income.
- Tax-deferred bucket: money you never paid tax on, taxed as ordinary income when withdrawn, such as Traditional 401(k) and IRA balances and most pensions.
- Tax-free bucket: money that comes out with no federal income tax, such as qualified Roth withdrawals, HSA distributions for medical costs, and municipal bond interest.
Social Security straddles the line: part of it is often taxable, and part is always tax-free. Annuities split too, depending on how they were funded. The sections below walk each source and its exact tax treatment under 2026 rules.
How is Social Security taxed in retirement?
Social Security is partially taxable: depending on your other income, 0%, 50%, or up to 85% of your benefit is included in taxable income. At least 15% of every benefit is always federally tax-free. Taxability is set by “provisional income,” a formula that adds half your benefit to your other income plus any tax-exempt interest.
The IRS uses provisional income (also called combined income) to decide how much of your benefit is taxed. The thresholds are fixed by statute and are not adjusted for inflation, so more retirees cross them each year.
| Filing status | Provisional income | Share of benefit taxable |
|---|---|---|
| Single | Under $25,000 | 0% |
| Single | $25,000 to $34,000 | Up to 50% |
| Single | Over $34,000 | Up to 85% |
| Married filing jointly | Under $32,000 | 0% |
| Married filing jointly | $32,000 to $44,000 | Up to 50% |
| Married filing jointly | Over $44,000 | Up to 85% |
“Up to 85% taxable” is a ceiling, not a rate. The taxable portion is added to your income and taxed at your ordinary bracket. For 2025 through 2028, a new senior deduction of $6,000 per person age 65 or older (created by OBBBA, P.L.119-21) stacks on top of the standard deduction, which can lower or erase the tax on Social Security for many middle-income retirees. That deduction phases out at higher incomes.
How are pension payments taxed?
Pension payments are taxed as ordinary income at your regular federal bracket, the same as a paycheck. The exception is any portion funded with after-tax contributions you already paid tax on, which comes back tax-free and is recovered gradually using the IRS Simplified Method. Most private and public pensions are fully taxable.
If you contributed after-tax dollars to your pension (common in some government and older private plans), that basis is returned across your expected payments and is not taxed again. Your Form 1099-R and the IRS Simplified Method worksheet show the taxable and tax-free split. For a deeper walkthrough, see our explainer on how a pension is taxed. Note that pensions do not qualify for capital-gains rates: every taxable dollar is ordinary income.
How are 401(k) and Traditional IRA withdrawals taxed?
Withdrawals from a Traditional 401(k) or Traditional IRA are taxed as ordinary income at your federal bracket, because the money went in pre-tax and grew tax-deferred. Withdrawals before age 59½ usually add a 10% early-withdrawal penalty. Starting at your required beginning age, Required Minimum Distributions (RMDs) force taxable withdrawals whether you need the cash or not.
These accounts are the core of the tax-deferred bucket. Because every dollar is taxed at ordinary rates, a large Traditional balance can push you into higher brackets in your 70s once RMDs begin. Under SECURE 2.0, the RMD start age is 73 for people born 1951 to 1959 and rises to 75 for those born in 1960 or later (the earliest age-75 RMD year is 2035). Missing an RMD triggers a penalty of up to 25% of the shortfall, reduced to 10% if corrected promptly.
The 2026 ordinary brackets that apply to these withdrawals run from 10% to 37%. For a single filer, the 22% bracket starts at $50,400 and the 24% bracket runs to $201,775; for married filing jointly, 22% starts at $100,800 and 24% runs to $403,550. Because RMDs are a known future tax event, many retirees study whether to convert part of the balance to Roth in lower-income years before age 73, and the current RMD rules for 2026 lay out the tradeoffs.
Are Roth IRA and Roth 401(k) withdrawals tax-free?
Yes: qualified Roth IRA and Roth 401(k) withdrawals are entirely free of federal income tax, because contributions were made with after-tax dollars. A withdrawal is qualified when you are at least age 59½ and the account has met the 5-year rule. Roth IRAs also have no Required Minimum Distributions during the owner’s lifetime.
Roth accounts are the heart of the tax-free bucket, and a qualified distribution does not count toward provisional income, capital-gains thresholds, or the Net Investment Income Tax. That makes Roth dollars useful for controlling your tax bracket in any given year. Because a Roth conversion is uncapped, is taxable ordinary income in the year you do it, is irreversible, and must be completed by December 31, timing matters. You cannot convert an RMD, and a conversion is not itself subject to the Net Investment Income Tax.
How are annuities taxed?
Annuity taxation depends on how the annuity was funded. A non-qualified annuity (bought with after-tax money) is taxed using the exclusion ratio: the return of your principal is tax-free and only the earnings are taxed as ordinary income. A qualified annuity (held inside an IRA or 401k) is fully taxable as ordinary income.
For non-qualified annuities, the exclusion ratio spreads your original principal across the expected payments so that part of each check is a tax-free return of basis and part is taxable earnings. Once you have recovered all your basis, later payments are fully taxable. Withdrawals of earnings before age 59½ can add a 10% early-withdrawal penalty, and annuity earnings are generally taxed as ordinary income, not at capital-gains rates.
How is taxable brokerage income taxed?
Taxable brokerage income is taxed by type. Qualified dividends and long-term capital gains (assets held more than one year) get preferential capital-gains rates of 0%, 15%, or 20%. Interest, non-qualified dividends, and short-term gains are taxed as ordinary income. Municipal bond interest is generally free of federal income tax.
A regular (taxable) brokerage account is flexible because you control when you sell and therefore when you realize gains. The 2026 long-term capital-gains breakpoints are shown below.
| Long-term capital-gains rate | Single (taxable income) | Married filing jointly |
|---|---|---|
| 0% | Up to $49,450 | Up to $98,900 |
| 15% | $49,451 to $545,500 | $98,901 to $613,700 |
| 20% | Over $545,500 | Over $613,700 |
Higher earners may also owe the Net Investment Income Tax of 3.8% on investment income once modified adjusted gross income tops $200,000 (single) or $250,000 (married filing jointly). Municipal bond interest stays federally tax-free but still counts toward the provisional income that taxes your Social Security, so tax-exempt does not always mean invisible.
Is part-time work in retirement taxed, and does it affect Social Security?
Yes: wages or self-employment income from part-time work in retirement are taxed as ordinary income, plus payroll taxes. If you claim Social Security before your full retirement age and keep working, the earnings test can temporarily withhold part of your benefit once your wages pass an annual limit. After full retirement age, the earnings test no longer applies.
The withheld benefits are not lost forever: the Social Security Administration recalculates and restores them once you reach full retirement age (between 66 and 67 depending on birth year). Earned income can also make more of your Social Security taxable by raising your provisional income, so part-time work can have a layered tax effect. Self-employment income also carries the 15.3% self-employment tax.
How is rental income taxed in retirement?
Rental income is taxed as ordinary income, but you are taxed on net income, not gross rent. You subtract operating expenses, mortgage interest, property taxes, and depreciation from the rent collected, which often shelters a meaningful share of the cash flow. Depreciation you claimed is later “recaptured” and taxed when you sell the property.
Rental income sits in the taxable bucket, but the deductions available (repairs, insurance, management fees, and the annual depreciation write-off) frequently reduce the taxable amount well below the cash you actually receive. When you sell, gain attributed to depreciation is taxed as unrecaptured Section 1250 gain at up to 25%, while the rest is a long-term capital gain. Rental income can also be subject to the 3.8% Net Investment Income Tax at higher income levels.
What about an HSA as a retirement income source?
A Health Savings Account (HSA) is a tax-free income source when used for qualified medical expenses: contributions were deductible, growth is untaxed, and withdrawals for medical costs are tax-free. After age 65, you can withdraw for any purpose without the 20% penalty, but non-medical withdrawals are then taxed as ordinary income, similar to a Traditional IRA.
Because retirees face large healthcare and Medicare costs, an HSA kept for qualified medical use is one of the few triple tax-advantaged buckets available, which is why many savers preserve it as a dedicated late-retirement health fund.
Which retirement income is not taxed?
Several retirement income streams escape federal income tax: qualified Roth IRA and Roth 401(k) withdrawals, HSA withdrawals for qualified medical costs, municipal bond interest, the portion of Social Security below the taxability thresholds (at least 15% is always tax-free), the return-of-principal part of a non-qualified annuity, and up to $250,000 (single) or $500,000 (married) of gain on a primary home sale.
These sources make up the tax-free bucket and give you room to add income in a year without raising your bracket, your Medicare premium, or the tax on your Social Security. For a source-by-source list, see our companion piece on tax-free retirement income sources. Building this bucket ahead of time, often through Roth conversions in lower-income years, is what gives a retiree flexibility later.
Retirement income tax cheat sheet
This table maps every common source of retirement income to its tax bucket and the rate that applies under 2026 rules. Reading across the rows shows which dollars are relatively cheap to spend and which are expensive, so a retiree can compare how ordinary-income sources, capital-gains sources, and fully tax-free sources stack up side by side before deciding which account to draw from in a given year.
| Income source | Tax bucket | How it is taxed (2026) |
|---|---|---|
| Social Security | Partly taxable | 0% to 85% included, taxed at ordinary rates; at least 15% always tax-free |
| Pension | Tax-deferred | Ordinary income; after-tax basis returns tax-free |
| Traditional 401(k) / IRA | Tax-deferred | Ordinary income; RMDs at 73 or 75; 10% penalty before 59½ |
| Roth IRA / Roth 401(k) | Tax-free | Tax-free if qualified (59½ plus 5-year rule); no lifetime RMD on Roth IRA |
| Non-qualified annuity | Split | Principal tax-free (exclusion ratio); earnings ordinary income |
| Brokerage: qualified dividends / long-term gains | Taxable | Capital-gains rates 0% / 15% / 20% |
| Brokerage: interest / short-term gains | Taxable | Ordinary income |
| Municipal bond interest | Tax-free | Federally tax-free (still counts for Social Security taxability) |
| Part-time work | Taxable | Ordinary income plus payroll or self-employment tax |
| Rental income | Taxable | Ordinary income on net rent; depreciation recapture at sale |
| HSA (qualified medical) | Tax-free | Tax-free for medical; ordinary income if non-medical after 65 |
How to build a tax-efficient retirement income mix
A tax-efficient retirement income mix blends the three buckets so you fill up low tax brackets with cheap dollars and avoid spiking into high ones. Once you know how each source is taxed, the next step is sequencing: deciding the order you draw from taxable, tax-deferred, and tax-free accounts each year to keep your lifetime tax bill low.
Holding all three buckets gives you levers. In a low-income year you might realize long-term gains inside the 0% capital-gains band, or convert some Traditional IRA to Roth to fill the 12% or 22% bracket before RMDs begin. In a high-income year you might lean on the tax-free bucket to avoid tipping into the 24% bracket, the Net Investment Income Tax, or a higher Medicare premium. The order in which you spend accounts, called the withdrawal sequence, can change your total tax over retirement.
Our guide on the tax-efficient withdrawal strategy explains sequencing across accounts and how to position assets so the right money is available at the right time. Many investors find that the work of building the tax-free bucket, often through Roth conversions in the years between retirement and age 73, is what makes a low-tax withdrawal plan possible.

Frequently asked questions
What are the 3 main sources of retirement income?
The three main sources of retirement income are traditionally described as Social Security, employer plans (pensions and 401(k)-type accounts), and personal savings and investments (IRAs and taxable brokerage accounts). This is often called the “three-legged stool.” Today many retirees add a fourth leg from part-time work, and a tax-aware plan also weighs Roth, annuity, and rental income.
What is the most common source of retirement income?
Social Security is the most common source of retirement income in the United States, received by the large majority of Americans age 65 and older, and for many households it supplies a substantial share of their total income. Because at least 15% of the benefit is always federally tax-free, Social Security is also one of the more tax-friendly income streams a retiree relies on.
Which types of retirement income are not taxed?
Retirement income that is not federally taxed includes qualified Roth IRA and Roth 401(k) withdrawals, HSA withdrawals for qualified medical expenses, municipal bond interest, the return-of-principal portion of a non-qualified annuity, the tax-free share of Social Security, and up to $250,000 (single) or $500,000 (married) of gain when you sell your primary home.
How is retirement income taxed?
Retirement income is taxed by category, not as one lump. Traditional 401(k), IRA, and pension income is taxed as ordinary income at your federal bracket. Qualified dividends and long-term capital gains get lower capital-gains rates of 0%, 15%, or 20%. Qualified Roth withdrawals and HSA medical withdrawals are tax-free, and Social Security is partially taxable based on your provisional income.
How much can a retiree earn without paying taxes?
It depends on filing status and age. In 2026 the standard deduction is $16,100 for singles and $32,200 for married couples filing jointly, plus an extra $2,050 (single) or $1,650 per spouse for those 65 and older. A temporary $6,000 senior deduction per person 65-plus applies for 2025 through 2028, so many older retirees can receive well over $20,000 before any federal income tax is due.
What is the best source of income in retirement?
There is no single best source; the more useful goal is a mix across all three tax buckets. Tax-free Roth and HSA dollars give flexibility, Social Security offers inflation-adjusted lifetime income with a tax-free floor, and taxable and tax-deferred accounts fill in the rest. Diversifying by tax treatment, not just by asset, is what gives a retiree control over each year’s tax bill.
How many sources of retirement income should you have?
There is no required number, but having income across the three tax buckets (taxable, tax-deferred, and tax-free) generally gives the most flexibility to manage taxes year to year. Many retirees draw from four or more sources, such as Social Security, a Traditional IRA, a Roth account, and a brokerage account, which lets them choose which dollars to spend as tax rules change.
