Retirement Planning in the United States
The US retirement system is built on three pillars: Social Security, employer-sponsored retirement plans, and individual savings. This guide covers the tax treatment of retirement accounts, contribution limits, withdrawal rules, and strategies for tax-efficient retirement income.
Social Security
Social Security provides a foundation of retirement income:
- Full Retirement Age: 67 for those born after 1960
- Early Retirement: Available at 62 with permanently reduced benefits (up to 30% reduction)
- Delayed Retirement: Benefits increase by 8% per year delayed up to age 70
- Taxation: Up to 85% of benefits may be taxable if provisional income exceeds $25,000 single/$32,000 MFJ
Employer-Sponsored Retirement Plans
401(k) Plans
- Employee Contribution Limit: $23,500 (2025, indexed; ~$24,000 estimated for 2026)
- Catch-Up Contribution: $7,500 for age 50+
- Employer Match: Typical 3-6% of salary (discretionary)
- Roth 401(k): After-tax contributions available with tax-free withdrawals
403(b) and 457 Plans
- 403(b): For employees of public schools and tax-exempt organizations
- 457(b): For state and local government employees (same contribution limits as 401(k))
Individual Retirement Accounts (IRAs)

Medicare

Tax-Efficient Withdrawal Strategies
- Roth Conversion Ladder: Convert Traditional IRA to Roth IRA in lower-income years
- Asset Location: Hold tax-efficient assets in taxable accounts, bonds in tax-deferred accounts
- Qualified Charitable Distributions (QCDs): Direct IRA distributions to charity (up to $100,000/year) satisfy RMDs tax-free
- Social Security Timing: Delay Social Security to maximize guaranteed inflation-adjusted income
