For many federal employees, tax planning tends to revolve around TSP contributions, Roth versus traditional decisions, and retirement timing. Yet one of the most important annual decisions is often the simplest: should you itemize deductions or take the standard deduction?
With higher standard deductions and changes to the SALT rules in recent years, the answer is not as obvious as it once was. For 2025, federal employees should revisit this decision rather than simply defaulting to what they did last year.
The standard deduction remains historically high. For 2025, it is projected to be roughly $30,000 for married couples filing jointly and about $15,000 for single filers, with head of household falling in between. (Final numbers will be adjusted for inflation by the IRS.)
For many federal households—especially dual-income GS couples earning between $150,000 and $250,000—the standard deduction will still be difficult to beat. If your total itemized deductions do not exceed the standard deduction, itemizing produces no additional benefit and simply adds paperwork.
That is why most taxpayers, including many federal employees, have used the standard deduction since the tax law changes in 2018.
The key reason this discussion has resurfaced is the higher State and Local Tax (SALT) deduction cap for 2025. The SALT cap—previously limited to $10,000—has been raised significantly for most filers, allowing up to $40,000 in deductible state income and property taxes, subject to income phaseouts at higher earnings levels.
For federal employees living in higher-tax states such as California, New York, New Jersey, Maryland, or Virginia, this change may be meaningful. A senior GS or SES couple paying substantial state income taxes and property taxes could now exceed the standard deduction by a wide margin.
In other words, geography matters again.
For most federal households, the tipping point comes from a combination of property taxes, state income taxes, mortgage interest, and charitable contributions.
Consider a married GS-13 couple earning $210,000 in Virginia. If they pay $9,000 in state income tax, $8,000 in property taxes, $12,000 in mortgage interest, and give $4,000 to charity, their total potential itemized deductions would be around $33,000. Compared to a projected $30,000 standard deduction, itemizing may save some money—but not dramatically more. In many cases, the difference may be modest after accounting for income phase rules and limitations.
Now compare that to a senior executive household earning $375,000 in a higher-tax state. If they pay $22,000 in state income taxes, $18,000 in property taxes, $18,000 in mortgage interest, and give $10,000 to charity, their itemized deductions could approach $68,000. Even with the SALT cap applied, that total far exceeds the standard deduction. For this household, itemizing would likely produce significant tax savings.
The difference between these two scenarios illustrates the central issue: income level, housing costs, and state taxes drive the outcome.
Unique Considerations for Federal Employees
Federal employees have a few tax characteristics that influence this decision.
FEHB premiums are generally paid with pre-tax dollars through payroll, so they typically do not create an additional deduction opportunity. Traditional TSP contributions reduce adjusted gross income but do not count as itemized deductions. However, lowering AGI can affect thresholds for medical expense deductions and other phaseouts.
For retirees, the analysis may shift again. A federal retiree drawing a FERS pension, Social Security, and TSP withdrawals may see different state tax treatment depending on where they live. Some states partially or fully exempt federal pensions, which reduces SALT exposure and may make the standard deduction more attractive.
When the Standard Deduction Still Wins
Many federal employees nearing retirement have paid down their mortgages or refinanced at lower balances. Without substantial mortgage interest, it becomes harder to exceed the standard deduction. Similarly, those living in lower-tax states or with moderate charitable giving often find that itemizing provides little additional benefit.
There is also a simplicity factor. The standard deduction reduces recordkeeping, documentation requirements, and audit exposure. For households close to the break-even point, simplicity may carry real value.
The decision to itemize should not always be evaluated in isolation for a single year. Federal employees can sometimes benefit from “bunching” deductions. For example, concentrating charitable contributions into one tax year while using the standard deduction in alternate years can increase total tax efficiency over time. Donor-advised funds make this easier.
Similarly, major medical procedures or large property tax payments can sometimes be timed. In retirement, coordinating Roth conversions with years of lower deductions may also improve long-term tax outcomes.
In other words, the itemize-versus-standard question is part of a broader tax sequencing strategy, especially for those within ten years of retirement.
For many federal employees earning under roughly $250,000 in household income, the standard deduction will likely remain competitive or superior. For higher-income households in high-tax states—particularly senior GS or SES employees—the increased SALT cap makes itemizing worth serious consideration again.
The key is not to assume. Run the numbers both ways. What worked in 2022 or 2023 may not be optimal in 2025.
For federal employees, tax planning is not just about minimizing this year’s bill. It is about preserving more of your income for long-term financial security in retirement.
