The most reliable way to lower your tax bracket before retirement is to shrink your taxable income in the years you still have earned wages: max out pre-tax retirement accounts, fund a Health Savings Account, bunch charitable gifts, harvest investment losses, and time bonuses, option exercises, and Roth conversions so income lands in the years where it’s taxed least. For 2026, a single filer crosses from the 24% bracket into the 32% bracket at $201,775 of taxable income; a married couple filing jointly hits the same jump at $403,550. Every dollar you legally keep under those thresholds is money taxed at a materially lower rate.
Know Where the 2026 Brackets Break
Federal income tax is progressive, so only the income inside a given range is taxed at that range’s rate. Knowing where the next jump sits tells you how much income you need to shelter. For 2026, the single-filer brackets are 10% up to $12,400, 12% to $50,400, 22% to $105,700, 24% to $201,775, 32% to $256,225, 35% to $640,600, and 37% above that. Married-filing-jointly thresholds run roughly double through the 32% bracket, with the 32% bracket beginning at $403,550 and the top 37% rate starting at $768,700.1Internal Revenue Service. Rev. Proc. 2025-32
The standard deduction reduces your taxable income before the brackets apply: $16,100 for single filers and $32,200 for married couples filing jointly in 2026.2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Anything you can do to lower gross income, or to take deductions above that floor, chips away at the top slice of what you owe.
Max Out Pre-Tax Retirement Contributions
Traditional 401(k) and 403(b) contributions come out of your paycheck before federal income tax is calculated, which makes them the single strongest bracket-reduction tool for most workers. For 2026, the employee deferral limit is $24,500.3Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 If you’re 50 or older, a standard catch-up adds $8,000, bringing your maximum deferral to $32,500.4Internal Revenue Service. Notice 2025-67 – 2026 Amounts Relating to Retirement Plans and IRAs
There’s a bigger window for one narrow age band. If you turn 60, 61, 62, or 63 during 2026, a SECURE 2.0 “super” catch-up of $11,250 replaces the standard $8,000, raising your maximum employee deferral to $35,750.4Internal Revenue Service. Notice 2025-67 – 2026 Amounts Relating to Retirement Plans and IRAs It disappears once you turn 64, so the years it applies are prime time for aggressive bracket management.
Traditional IRAs work the same way, at a smaller scale. The 2026 limit is $7,500, with a $1,100 catch-up at age 50 or older.3Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500 Whether the contribution is deductible depends on your income and whether you or your spouse is covered by a workplace plan. Even a partial deduction is worth claiming.
Bigger Plans for the Self-Employed
Freelancers and business owners can shelter far more. A SEP IRA accepts up to 25% of net self-employment income, capped at $72,000 for 2026, and the full contribution is deductible.5Internal Revenue Service. SEP Contribution Limits (Including Grandfathered SARSEPs) A solo 401(k) lets you contribute as both employee (up to $24,500 plus any catch-up) and employer (up to 25% of compensation), with a combined base cap of $72,000. Someone aged 60 to 63 using the super catch-up can push the total to $83,250. If you expect your income to fall sharply in retirement, these plans let you move an enormous slice of a high-earning year into a future one.
Fund a Health Savings Account
If you’re covered by a qualifying high-deductible health plan, an HSA delivers a deduction you can take whether or not you itemize, and the money grows and comes out tax-free when spent on medical expenses.6Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans The 2026 contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, plus a $1,000 catch-up at age 55 or older. To qualify, your plan’s annual deductible must be at least $1,700 (self-only) or $3,400 (family).7Internal Revenue Service. Rev. Proc. 2025-19
A 58-year-old couple on a family HDHP can deduct up to $9,750 from gross income in a single year. Unused HSA balances roll forward indefinitely and can be invested, which is why many people approaching retirement deliberately overfund an HSA to cover healthcare expenses later. Excess contributions above the annual limit trigger a 6% excise tax for each year they stay in the account, so track the ceiling.
Bunch Charitable Gifts to Beat the Standard Deduction
Charitable donations only reduce taxable income if you itemize, and itemizing only pays off when your total deductions clear the standard deduction. That’s a high bar in 2026: $16,100 single, $32,200 joint.2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
Bunching solves this. Instead of giving the same amount every year and never clearing the floor, you pile two or three years’ worth of donations into one year, itemize that year, and take the standard deduction the rest of the time. A donor-advised fund makes the mechanics simple: you contribute a lump sum, claim the full deduction now, and direct grants to charities over the following years.8Internal Revenue Service. Donor-Advised Funds Cash gifts to most public charities are deductible up to 60% of AGI; appreciated stock is limited to 30% of AGI, but donating stock also avoids capital gains tax on the appreciation.9Office of the Law Revision Counsel. 26 U.S. Code 170 – Charitable, Etc., Contributions and Gifts
Once you turn 70½ and have a traditional IRA, a qualified charitable distribution can send up to $111,000 per year directly from the IRA to a qualifying charity. The QCD satisfies your required minimum distribution without adding to adjusted gross income, which is stronger than a deduction because it protects the AGI-driven cliffs (Medicare premiums, Social Security taxability) rather than just reducing taxable income.
Convert to Roth in Low-Income Years
A Roth conversion moves money from a traditional IRA or 401(k) into a Roth IRA. You pay ordinary income tax on the converted amount this year; in exchange, the money grows and comes out tax-free, and Roth balances don’t drive required minimum distributions.10Internal Revenue Service. Publication 590-A – Contributions to Individual Retirement Arrangements (IRAs) RMDs from traditional accounts start at 73.
The strategy fits a specific window. If you retire or scale back at 62, delay Social Security until 67, and don’t face RMDs until 73, you likely have several years of unusually low taxable income. Converting during those years fills up the 10%, 12%, and 22% brackets on purpose, so that money isn’t forced out later at a higher rate.11Office of the Law Revision Counsel. 26 USC 408A – Roth IRAs Convert too much in one year and you push yourself into a bracket that defeats the point; spreading conversions across several years keeps each year’s bill manageable. Amounts that must come out as an RMD for the year can’t be converted, so this works best before RMDs begin.
Time When Income Arrives
Controlling when income lands is as useful as reducing it. Non-qualified deferred compensation plans let executives and key employees postpone salary or bonuses to a future year, often after retirement, and the deferred amounts aren’t taxed until paid out.12Internal Revenue Service. Nonqualified Deferred Compensation Audit Technique Guide Deferred pay is typically an unsecured promise from the employer, so if the company fails, you’re a general creditor. Weigh that risk against the tax savings.
Simpler moves add up too. If your employer will pay a year-end bonus in January instead of December, the income moves into the next tax year. Exercising nonqualified stock options in a year with lower other income means the ordinary-income portion is taxed at a lower marginal rate. If you’re already planning to step back from full-time work, delaying an option exercise or a large gain until that first slower year can be worth thousands.
Harvest Investment Losses
Selling investments at a loss offsets capital gains elsewhere in your portfolio. When losses exceed gains for the year, up to $3,000 of the remainder can be applied against ordinary income ($1,500 if married filing separately), and unused losses carry forward indefinitely.13Office of the Law Revision Counsel. 26 USC 1211 – Limitation on Capital Losses The $3,000 ordinary-income deduction is modest, but wiping out a $50,000 capital gain avoids 15% or 20% tax that would otherwise leave your portfolio.
The wash-sale rule disallows the loss if you buy a substantially identical security within 30 days before or after the sale.14Office of the Law Revision Counsel. 26 U.S. Code 1091 – Loss From Wash Sales of Stock or Securities You can keep market exposure by replacing the sold holding with a similar but not identical fund.
High earners also face a 3.8% net investment income tax when modified adjusted gross income exceeds $200,000 (single) or $250,000 (joint). These thresholds are not indexed for inflation, so more taxpayers cross them each year.15Office of the Law Revision Counsel. 26 USC 1411 – Imposition of Tax Strategies that lower AGI below the trigger, or that reduce net investment income directly, can eliminate the surtax on part of your returns.
Protect Yourself From Medicare IRMAA
Your bracket isn’t the only income-driven cliff near retirement. Medicare Part B and Part D premiums are surcharged through Income-Related Monthly Adjustment Amounts based on MAGI from two years earlier. For 2026, the surcharges start at MAGI above $109,000 (single) or $218,000 (joint) and climb through five tiers, reaching $487.00 per person per month at $500,000+ single or $750,000+ joint.16Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles At the top tier, a couple pays nearly $12,000 a year in Part B surcharges alone.
Because IRMAA uses a two-year lookback, the years right before and right after age 65 are the ones that count. A large Roth conversion, option exercise, or property sale at 63 inflates your Medicare premiums at 65. The same retirement contributions, HSA deductions, bunched giving, and loss harvesting that pull you into a lower federal bracket also keep IRMAA lower.
What It Looks Like Combined
The tactics compound. Take a 61-year-old married couple earning $450,000 jointly. Without planning, roughly $46,000 of their income sits in the 32% bracket. If each spouse maxes out a 401(k) with the super catch-up ($35,750 apiece), they fund a family HSA with the catch-up ($9,750), and they bunch $20,000 of charitable giving through a donor-advised fund, they’ve cut AGI by more than $101,000. That’s enough to bring most or all of their income back into the 24% bracket, and it lowers the MAGI figure that will drive their Medicare premiums two years later.
Which combination fits you depends on your income, your age, your filing status, and whether you expect retirement to bring more taxable income or less. A worker with a large pension and heavy future RMDs may lean on Roth conversions. A saver in their early sixties with a modest nest egg may go all-in on deductible contributions while earned income still supports them. The last several working years hold a concentration of levers that vanish once wages stop and required distributions begin, so the planning is worth doing while the options are still open.
