2026 Federal Tax Brackets for Federal Employees and Retirees
The 2026 federal tax brackets apply to income earned from January 1, 2026, through December 31, 2026. You will use these rates when filing your 2026 federal income tax return in early 2027.
For federal employees and retirees, the 2026 tax numbers matter for more than regular wages. They can affect federal retirement planning, TSP contributions, FERS or CSRS pension taxation, Roth conversion planning, Social Security timing, required minimum distributions, and federal tax withholding.
This guide explains the 2026 federal income tax brackets, standard deduction amounts, senior deduction rules, TSP contribution limits, Social Security wage base, SALT deduction cap, and tax planning considerations for federal employees and retirees.
This article is based on official IRS, SSA, TSP, and OPM guidance for tax year 2026. It is intended for educational purposes and should not be treated as personal tax advice.
Quick Answer: What Are the 2026 Federal Tax Brackets?
For tax year 2026, the federal income tax rates remain:
10%, 12%, 22%, 24%, 32%, 35%, and 37%.
The top 37% tax bracket begins at taxable income over:
Important: These brackets apply to taxable income, not gross income. Taxable income is generally your income after eligible adjustments, deductions, and either the standard deduction or itemized deductions.
2026 Standard Deduction Amounts
The standard deduction reduces your taxable income before federal tax brackets are applied.
For many taxpayers, especially retirees who no longer have large mortgage interest or itemized deductions, the standard deduction may be the simpler and larger option.

Single Filers
Married Filing Jointly
Head of Household
Married Filing Separately
Additional Standard Deduction for Age 65 or Blindness
For 2026, taxpayers who are age 65 or older, or legally blind, may add an extra amount to their standard deduction.
This applies per qualifying condition. For example, if both spouses on a joint return are age 65 or older, they may add $3,300 to their standard deduction.
New 2026 Senior Deduction
A separate senior deduction is available from 2025 through 2028 for eligible taxpayers age 65 or older.
For 2026:
This senior deduction is separate from the existing age 65 additional standard deduction. It may help some federal retirees reduce taxable income from pensions, TSP withdrawals, IRA withdrawals, or other taxable retirement income.
How Federal Tax Brackets Work
The United States uses a marginal tax system. This means your income is taxed in layers.
For example, being in the 22% bracket does not mean all your income is taxed at 22%. Only the portion of taxable income inside the 22% bracket is taxed at 22%.
Your marginal tax rate is the rate applied to your next dollar of taxable income. Your effective tax rate is the average tax rate you actually pay across your total income.
Need Help Applying the 2026 Tax Brackets to Your Federal Retirement Plan?
Knowing the tax brackets is only the first step. For federal employees and retirees, the bigger question is how your FERS pension, CSRS pension, TSP withdrawals, Roth TSP strategy, Social Security timing, and tax withholding work together.

Example 1: Single Federal Employee With Traditional TSP Contributions
Assume a single federal employee earns $110,000 in salary and contributes $10,000 to the traditional TSP.
Simplified calculation:
Estimated federal tax before credits:
Estimated federal income tax before credits: $13,170.
Planning takeaway: Traditional TSP contributions can reduce current federal taxable income. Roth TSP contributions do not reduce current taxable income, but qualified Roth withdrawals may be tax-free later.
Example 2: Married Federal Couple Filing Jointly
Assume a married federal couple has $180,000 of combined income and contributes $20,000 to traditional TSP accounts.
Estimated federal tax before credits:
Estimated federal income tax before credits: $17,540.
Planning takeaway: For married federal employees, TSP contribution timing can affect taxable income, withholding, and eligibility for certain tax deductions or credits.
Example 3: Federal Retiree With Pension and TSP Withdrawals
Assume a single FERS retiree age 67 has:
- $45,000 in taxable pension income
- $20,000 in traditional TSP withdrawals
- No itemized deductions
- No taxable Social Security included in this simplified example
Estimated federal tax before credits:
Estimated federal income tax before credits: $4,654.
Planning takeaway: Federal retirees should review how pension income, TSP withdrawals, Roth withdrawals, Social Security, and deductions interact before choosing a withdrawal strategy.
2026 Long-Term Capital Gains Tax Rates
Long-term capital gains generally apply to assets held for more than one year. These gains are taxed at 0%, 15%, or 20%, depending on taxable income.
These thresholds are based on taxable income, not just the size of the investment gain.
High-income taxpayers may also owe the 3.8% Net Investment Income Tax, depending on income and investment income type.
2026 Social Security Wage Base
For 2026, the Social Security taxable wage base is $184,500.
Employees pay 6.2% Social Security tax on wages up to that amount.
Maximum employee Social Security tax for 2026:
$184,500 x 6.2% = $11,439
Earnings above the Social Security wage base are not subject to the 6.2% Social Security tax. However, Medicare tax still applies because Medicare has no wage cap.
2026 TSP and Retirement Contribution Limits
The 2026 retirement contribution limits increased for several accounts.
For federal employees, the $24,500 employee deferral limit applies to the combined total of traditional TSP and Roth TSP contributions. If you are comparing pre-tax and after-tax savings, review how Roth TSP vs Traditional TSP decisions may affect your current tax bill and future retirement withdrawals.
Federal employees should also watch the new Roth catch-up rule. Beginning in 2026, certain higher earners must make catch-up contributions as Roth contributions if their prior-year wages from TSP-eligible employment exceed the applicable IRS threshold.
2026 SALT Deduction Cap
The State and Local Tax deduction, often called the SALT deduction, applies only if you itemize deductions.
For 2026, the SALT deduction cap is:
The SALT cap is reduced if modified adjusted gross income is more than $505,000, or more than $252,500 for married filing separately. It cannot be reduced below $10,000, or $5,000 for married filing separately.
This may matter most for federal employees and retirees in higher-tax states who pay significant state income tax, property tax, or local tax and already itemize deductions.
How 2026 Tax Brackets Affect Federal Employees
Federal employees should review the 2026 tax brackets before changing TSP elections, choosing traditional versus Roth contributions, or adjusting paycheck withholding.
Key planning points:
- Traditional TSP contributions generally reduce current federal taxable income.
- Roth TSP contributions do not reduce current taxable income.
- TSP catch-up limits increase for employees age 50 or older.
- Employees ages 60 to 63 may qualify for a higher catch-up limit.
- Reaching the TSP limit too early may affect agency matching if contributions stop before the final pay period.
- Tax brackets can affect whether Roth conversions or Roth TSP contributions make sense.
- Federal employees with side income, investment income, rental income, or a spouse’s income may need to review withholding.
How 2026 Tax Brackets Affect Federal Retirees
Federal retirees may have several taxable income sources. A strong FERS pension planning strategy should account for pension income, TSP withdrawals, Social Security, Roth conversions, and required minimum distributions before retirement decisions are finalized.
Common taxable income sources may include:
- FERS pension
- CSRS pension
- Traditional TSP withdrawals
- Traditional IRA withdrawals
- Taxable investment income
- Part of Social Security benefits
- Roth conversion income
- Required minimum distributions
A FERS or CSRS annuity may include a taxable portion and a tax-free recovery of employee contributions. Traditional TSP withdrawals are generally taxable as ordinary income. Qualified Roth TSP withdrawals may be tax-free.
The main planning issue is timing. Your Social Security timing decision may affect lifetime income, taxable income, survivor planning, and how much you need to withdraw from TSP or IRA accounts.
2026 Tax Planning Checklist for Federal Employees
Use this checklist before the end of 2026:
- Review your current federal tax bracket.
- Check whether traditional TSP contributions could reduce taxable income.
- Compare traditional TSP versus Roth TSP based on current and future tax rates.
- Confirm you are contributing enough each pay period to receive full agency matching.
- Review catch-up contribution eligibility if you are age 50 or older.
- Review the higher catch-up limit if you are age 60 to 63.
- Adjust Form W-4 if income, deductions, credits, or family status changed.
- Account for side income, investment income, or spouse income.
- Review SALT deduction impact if you itemize.
- Speak with a tax professional before making major Roth conversion decisions.
2026 Tax Planning Checklist for Federal Retirees
Federal retirees should review:
- Pension withholding through OPM.
- TSP withholding on withdrawals.
- Whether Social Security benefits may become taxable.
- Whether required minimum distributions will push income into a higher bracket.
- Whether Roth conversions make sense before RMDs begin.
- Whether the new senior deduction applies.
- Whether the additional age 65 standard deduction applies.
- Whether itemizing deductions is better than taking the standard deduction.
- Whether state taxes affect retirement income.
- Whether survivor benefits could change household tax brackets later.
Common Mistake: Confusing Gross Income With Taxable Income
Tax brackets are based on taxable income.
For example, a single federal employee earning $100,000 is not automatically taxed as if their taxable income is $100,000. Traditional TSP contributions, eligible adjustments, and the standard deduction may reduce taxable income before the brackets apply.
That is why two employees with the same salary may owe different federal income tax amounts.
Common Mistake: Thinking One Bracket Applies to All Income
A taxpayer in the 24% bracket does not pay 24% on every dollar of income.
Instead, each layer of income is taxed at the rate assigned to that bracket. This is why your effective tax rate is usually lower than your marginal tax rate.
Common Mistake: Ignoring Retirement Withdrawal Timing
For retirees, the timing of TSP withdrawals can matter as much as the amount withdrawn. A planned TSP withdrawal strategy may help coordinate taxable income, Social Security, Roth conversions, and required minimum distributions over multiple years.
A large traditional TSP withdrawal in one year may increase taxable income, affect Medicare premium brackets, increase the taxable portion of Social Security, or reduce eligibility for certain deductions. A more planned withdrawal strategy may help smooth taxable income over multiple years.
Plan Before You Make a Tax or Retirement Decision
A single tax year can affect more than your return. TSP withdrawals, Roth conversions, pension income, Social Security timing, and required minimum distributions can all change your taxable income.
Federal Pension Advisors can help you review your retirement income picture before you make major decisions.

Bottom Line
The 2026 federal tax brackets keep the same seven tax rates, but the income thresholds and standard deduction amounts have increased. For federal employees, the most important planning areas are TSP contributions, withholding, Roth versus traditional decisions, and catch-up contribution rules.
For federal retirees, the key issues are pension taxation, TSP withdrawals, Social Security taxation, Roth conversions, required minimum distributions, and whether the new senior deduction applies.
Tax brackets are only one part of retirement tax planning. Before making major TSP, Roth conversion, Social Security, or withdrawal decisions, consider working with a qualified tax professional or a team that specializes in federal employees wealth management and retirement income planning.
