Retirement often feels like a tax break, but the reality surprises most people. Withdrawals from traditional IRAs and 401(k)s count as ordinary income, which means they're taxed at your regular rate. Add Social Security benefits to the mix, and your tax bracket can stay as high as it was during your working years.

Here's the trap: up to 85 percent of your Social Security benefits become taxable if your combined income exceeds certain thresholds. The IRS combines adjusted gross income, nontaxable interest, and half your Social Security benefits to calculate this. For a married couple filing jointly, combined income over $32,000 triggers taxation on benefits. For single filers, the limit sits at $25,000. These thresholds haven't budged since 1984, so inflation pushes more retirees into this tax zone every year.

Financial advisers recommend three strategies to trim the damage.

First, manage the timing of withdrawals. Retirees with flexibility can pull from taxable brokerage accounts before tapping retirement accounts. This keeps taxable income lower and reduces the portion of Social Security benefits subject to tax. The math works especially well in early retirement years when you might have lower income overall.

Second, consider Roth conversions. Converting traditional IRA or 401(k) funds to a Roth IRA creates a one-time tax bill but locks in future tax-free growth. Done strategically in lower-income years, conversions can smooth lifetime tax exposure.

Third, maximize charitable contributions if you're a high earner. Qualified charitable distributions directly from IRAs to charities reduce taxable income without triggering the Social Security benefit tax. You must be 70 and a half, but the strategy works powerfully for those giving away money anyway.

The takeaway for savers: retirement tax planning starts
