Traditional IRAs
Distributions are generally included in taxable income, subject to applicable rules and any after-tax basis that may exist.
Retirement Taxes
How will your income be taxed in retirement?
Retirement does not eliminate taxes—it changes where your income comes from and how different sources may be taxed. Understanding those differences can help you see how withdrawals, Social Security, pensions, investments and Roth accounts fit together.
Skyline Retirement provides general retirement tax education—not personalized tax, investment, insurance, legal or accounting advice or recommendations. Tax treatment depends on individual circumstances and applicable rules.

Start With The Basics
How is retirement income taxed?
Retirement income is not taxed under one universal rule. Withdrawals from traditional tax-deferred retirement accounts are generally taxable as ordinary income, qualified Roth distributions are generally free from federal income tax when applicable requirements are satisfied, Social Security benefits may be partly taxable depending on income, and taxable investment accounts can generate interest, dividends and capital gains. The overall tax result depends on the combination and timing of those income sources.
Different Income. Different Rules.
Your retirement income sources may not be taxed the same way.
One of the most important retirement-tax concepts is understanding which accounts create taxable income when money comes out—and which may receive different treatment.
401(k)s and workplace plans
Pre-tax contributions and earnings are generally taxed when distributed, subject to the rules of the account.
Roth accounts
Qualified distributions are generally free from federal income tax when applicable requirements are satisfied.
Social Security
A portion of benefits may become taxable depending on other income and the applicable federal calculation.
Pensions
Pension payments can be taxable, but treatment can depend on how contributions were made and the structure of the plan.
Investments
Interest, dividends and realized gains can be taxed differently, making the type of income important—not simply the amount withdrawn.
The Bigger Picture
Your tax return does not see each retirement decision in isolation.
Taking additional income from one account can affect more than the tax on that withdrawal. It can change your marginal tax bracket, Social Security taxation, Medicare income calculations and the taxation of other income.
The timing of income can matter just as much as the source.
Retirement tax planning is often about coordinating income—not simply minimizing taxes in one year.

Connected Decisions
Retirement taxes connect to nearly every major income decision.
Seeing those connections can help you understand why a decision that appears isolated may create consequences elsewhere.
