You saved diligently for four decades, crossed the seven-figure line, and pictured a $40,000-a-year retirement. Then the first tax return arrives. If you are a single 65-year-old with roughly $1 million in savings, you may be shocked by what actually reaches your checking account. In this scenario, you may draw $40,000 annually, following the 4% rule. But your actual discretionary spending budget could be closer to $28,000.
A million-dollar nest egg plus Social Security no longer clears the average American household budget before taxes take their cut. The Bureau of Labor Statistics says average annual household spending hit $78,535 in 2024, well above the $66,000 gross income our retiree is generating.
Our 65-year-old has $850,000 in a traditional IRA or 401(k), $150,000 in a taxable brokerage account, and about $26,000 a year in Social Security. Nearly all of the $40,000 withdrawal comes from the traditional IRA, which means every dollar is taxed as ordinary income. That draw also triggers a second tax event: it drags Social Security into the taxable column.
The provisional-income formula uses fixed breakpoints that have never been indexed to inflation: $25,000 and $34,000 for single filers. Here is the walkthrough:
- Start with half of Social Security: half of $26,000 is $13,000.
- Add other taxable income: $13,000 plus the $40,000 IRA draw equals $53,000 of provisional income.
- Compare to the breakpoints: $53,000 sits far above the $34,000 upper threshold, so up to 85% of Social Security becomes taxable, roughly $22,000 of the $26,000 benefit.
That pushes taxable income to around $62,000 before the 2026 single-filer standard deduction of $16,100. What remains gets taxed at 10% up to $12,400, then 12% up to $50,400, then 22% above that. Federal tax lands in the $5,000 to $6,000 range for most filers in this profile.
The Medicare Layer at 65
Turning 65 hands you Medicare, but the “free” part is Part A. Part B has a standard 2026 premium of $202.90 per month and a $283 annual deductible. Income-related surcharges (IRMAA) do not apply here because they only start above $109,000 in modified adjusted gross income for single filers in 2026.
What still bites is the rest of the stack: Part D drug coverage, a Medigap or Medicare Advantage plan, dental and vision that Medicare does not cover, and routine out-of-pocket costs. A realistic all-in healthcare number for a healthy 65-year-old could cost $6,000 to $8,000 a year.
| Line Item | Amount |
|---|---|
| Traditional IRA withdrawal (4%) | $40,000 |
| Social Security | $26,000 |
| Gross retirement income | $66,000 |
| Federal income tax (est.) | -$5,500 |
| Medicare Part B premiums | -$2,435 |
| Part D, Medigap, dental, out-of-pocket | -$5,500 |
| State income tax (typical state) | -$2,500 |
| Baseline essentials (housing, food, transport, utilities) | -$22,000 |
| Real discretionary spending power | ~$28,000 |
Add in inflation. The 2026 Social Security COLA of 2.8% only partly offsets that pressure. Every year the fixed $25,000 and $34,000 provisional-income thresholds sit unchanged, more of your benefit gets taxed by default.
Two Strategies That Could Move the Needle
The strongest lever is diversifying where your dollars sit before you need them. If you are reading this before age 73, you still have a window worth studying carefully.
- Partial Roth conversions between retirement and RMD age. Convert enough from the traditional IRA each year to fill up the 12% bracket (which runs to $50,400 for single filers in 2026) without spilling into 22%. You pay tax now at known rates, shrink future required minimum distributions, and build a Roth bucket that funds tax-free withdrawals later .
- Blend draws from taxable and Roth accounts once built. Pulling part of your annual need from a brokerage account (taxed at long-term capital gains rates) or from a Roth (not taxed at all) can keep provisional income under $34,000 and cut how much Social Security gets taxed. That single move can add several thousand dollars a year in real spending.
Once RMDs begin, qualified charitable distributions let you send up to $108,000 a year directly from an IRA to a charity, satisfying the RMD without adding to taxable income or provisional income. This is a great option for charitably inclined retirees.
What to Do First
Model your current-year provisional income before you take next year’s withdrawal. If a smaller traditional draw plus a taxable-account top-up keeps you under $34,000, that alone can rescue thousands of dollars of Social Security from taxation. Experts advise against treating the 4% rule as gospel and drawing everything from the tax-deferred account because it is the biggest. With some smart planning, you can bump that $28,000 annual figure a bit higher.
