A single filer earning $80,000 keeps $280.50 more in 2027. At $200,000, a single filer keeps $124.60 less. Wider tax brackets and a larger standard deduction cut federal income tax in both cases, but at $200,000 the higher Social Security cap costs more than those tax savings.

These examples hold wages and deductions fixed, use the basic standard deduction, and estimate take-home pay before credits and state and local taxes. If you’re filing in spring 2027, you’ll generally use the 2026 tax brackets.

Compare your take-home pay

Start with the same salary to see what the 2027 rules do on their own. Then add a raise, a new premium or a different 401(k) contribution to see how much you’d keep.

What the new rules change: +$280.50
What your pay and deductions change: $0.00

An extra $33.23 per month in pretax premiums would use up the gain from the new rules if your pay and other deductions stay the same.

What changed from 2026 to 2027

Start with the figures that apply to you. Tax brackets and the Social Security wage cap affect what you keep from your wages. Health account limits affect how much you can set aside, and the cost-of-living adjustment affects your Social Security benefit. Each amount links to its source.

Federal income tax

The rates stay the same. A bigger standard deduction reduces taxable income, and wider brackets let you earn more before the next rate applies.

Social Security payroll tax

Each employee pays 6.2% of eligible wages up to the cap. If you earn more than the 2026 cap, more of your wages can be subject to Social Security tax in 2027.

HSA and health FSA limits

Count your employer’s HSA contribution when you decide how much to set aside. If your health FSA allows carryover, check the limit for the plan year in which the unused balance accrued.

Health FSA maximum optional carryoverplan year beginning in the stated year	$680.00	$700.00	+$20.00

Social Security benefits

The cost-of-living adjustment raises your benefit before deductions. If Medicare premiums come out of your check, the deposit can change by a different amount.

Why the same salary can leave you with less

At $80,000, the full gain comes from lower federal income tax. The worker earns less than the Social Security wage cap in both years, so that tax stays the same.

At $200,000, a single filer saves $359.00 in federal income tax and pays $483.60 more in Social Security tax. That’s the maximum increase per worker because the salary exceeds both years’ caps.

Who earns the wages matters for couples. At $200,000 in combined wages, a couple with two $100,000 earners keeps $561.00 more. A couple with one $200,000 earner keeps $77.40 more because Social Security applies its cap to each worker’s wages separately.

Same salary, single filer, federal income and employee payroll taxes. Basic standard deduction, no tax credits or pretax payroll deductions.

How much of a premium increase wipes out the tax savings?

For the single filer earning $80,000, about $33.23 more a month in pretax premiums uses up the tax savings. At $40 more a month, the increase costs $337.68 over the year after the tax break on those premiums. The worker ends up $57.18 behind. If you’re choosing a plan, use the health plan calculator to weigh that premium against what your employer contributes and what you expect to spend on care.

Retirement limits and Medicare premiums

If you’re deciding how much to save, you can enter your planned traditional 401(k) contribution above to see what it does to your paycheck. Our 401(k) and Roth IRA calculators use the 2026 limits. We’ll update this comparison once we can verify the 2027 limits against the IRS retirement limits release.

If Medicare Part B comes out of your Social Security check, the amount you keep depends on both the confirmed cost-of-living adjustment and your premium. See the Medicare Part B premium history for published rates.

How the take-home comparison works

Qualifying pretax health premiums reduce the wages we use for federal income tax, Social Security and Medicare. Traditional 401(k) contributions reduce wages for federal income tax only. We then apply the basic standard deduction and brackets to estimate federal income tax. The Medicare line includes Additional Medicare Tax above the threshold for your filing status.

We apply both years’ rules to your 2026 wages and deductions first. That shows what the new rules do on their own. Then we apply the 2027 rules to any new wages or deductions you enter. The difference between those two 2027 estimates shows what your choices and pay changes do to your take-home pay.

Filing in 2027 generally means preparing your 2026 return. The new 2027 tax brackets apply to 2027 income. Compare software costs for the return you are about to file.
