How to Get Less Taxes Taken Out of Your Paycheck

The fastest way to get less taxes taken out of your paycheck is to file a new Form W-4 with your employer that reflects the credits and deductions you’ll actually claim, and to move more of your compensation into pre-tax benefits like a 401(k), HSA, or FSA. Most workers are over-withheld, which means they’re giving the IRS an interest-free loan all year and getting it back as a refund. You can stop doing that as soon as your next payroll cycle.

Update Your W-4

Form W-4 is the single most direct lever you have over federal withholding. You can submit a new one to your employer at any time, there’s no limit on how often you update it, and the change takes effect with the next pay period.¹ The form now uses dollar amounts instead of the old “allowances” system, so each entry translates directly into a change in your per-paycheck withholding.

Run the IRS Estimator Before You Fill Anything In

Before touching the form, put your numbers through the IRS Tax Withholding Estimator at irs.gov. The tool walks you through your income, filing status, expected deductions, and credits, then tells you the exact dollar amounts to enter on each line of the W-4. Filling out the W-4 by guessing is how people end up over- or under-withheld. The estimator also handles situations the form can’t, like mid-year job changes or irregular income.

Step 3: Enter Your Credits

Step 3 is where you tell your employer about tax credits that will reduce your final bill. For 2026, the Child Tax Credit is $2,200 per qualifying child under 17, and the Credit for Other Dependents is $500 per qualifying dependent who doesn’t meet the child credit rules.² Add them together and enter the total. Payroll then spreads that credit value across your paychecks, lowering the withholding on each one.

Only claim credits you’ll actually qualify for. If your income sits near the Child Tax Credit phaseout, the estimator will catch that; the W-4 itself won’t.

Step 4: Deductions and Other Adjustments

Step 4 has three sub-lines that fine-tune your withholding.

Line 4(a) is for outside income that doesn’t have tax withheld automatically, such as interest, dividends, rental income, or side-business earnings. Entering an annual total here tells your employer to withhold extra from wages so the outside income doesn’t become a surprise bill in April. This one increases withholding, but it’s often the reason people who want less withheld from wages later can safely do so, because it prevents an underpayment elsewhere from eating their reduction.

Line 4(b) is for deductions above the standard amount. The withholding tables already assume the standard deduction: $16,100 for single filers and $32,200 for married couples filing jointly in 2026.³ If you itemize and your deductions clearly exceed the standard amount, enter the difference. That lowers your estimated taxable income and reduces withholding per paycheck. The W-4 instructions include a Deductions Worksheet for the calculation.² If your itemized total is only marginally higher than the standard deduction, the math usually isn’t worth the risk of under-withholding.

Line 4(c) is a flat extra amount withheld each pay period. It’s the line you leave blank or reduce when your goal is a smaller withholding, and it’s the line you add to when the estimator says you need more.

Route More Pay Through Pre-Tax Benefits

Adjusting the W-4 only changes the federal income tax portion of your paycheck. Pre-tax payroll deductions do something stronger: they lower the income that federal tax is calculated on in the first place, and in most cases they also escape Social Security and Medicare taxes. Dollar for dollar, this is the most efficient way to shrink total paycheck deductions.

Traditional 401(k)

Traditional 401(k) contributions are excluded from your current taxable income. For 2026, you can defer up to $24,500.⁴ If you’re 50 or older, add up to $8,000 in catch-up contributions, for a total of $32,500. Workers between 60 and 63 get an enhanced catch-up of $11,250, taking the total to $35,750. If you’re in the 22% bracket and defer the full $24,500, your federal income tax withholding drops by roughly $5,390 spread across the year’s paychecks. You’ll owe tax on the money when you withdraw it in retirement, but the paycheck impact right now is real.

Health Savings Account

An HSA is available only if you’re enrolled in a qualifying high-deductible health plan. Contributions are pre-tax, the balance grows tax-free, and withdrawals for qualified medical expenses are also tax-free. For 2026, the contribution limit is $4,400 for self-only coverage and $8,750 for family coverage.⁵ If you’re 55 or older and not on Medicare, you can add another $1,000. Employer contributions count toward these limits, so check what your employer puts in before setting your own.

An HSA is yours permanently. The balance carries over year to year, and you keep the account after a job change or retirement.

Flexible Spending Accounts

Health care FSAs let you set aside pre-tax money for out-of-pocket medical costs like copays, prescriptions, and dental work. The 2026 contribution limit is $3,400. These accounts operate on a use-it-or-lose-it basis, though many employers allow a carryover of up to $680 into the following year or offer a short grace period to spend the balance. You can’t have both a carryover and a grace period, so check your plan.

Dependent care FSAs cover eligible childcare and adult dependent care expenses. For 2026, the household limit is $7,500, or $3,750 if you’re married and filing separately. Both types reduce your taxable income dollar for dollar and lower withholding on each paycheck.

Commuter Benefits

If your employer offers a qualified transportation fringe benefit, you can use pre-tax dollars for parking near work and for transit passes or vanpool costs. For 2026, the monthly exclusion is $340 for qualified parking and $340 for transit, and they’re separate limits you can use at the same time.⁶ That’s up to $8,160 per year in pre-tax commuting costs if you use both. Not every employer offers this; if yours does and you aren’t enrolled, you’re leaving straightforward tax reduction on the table.

Fix Multi-Job Under-Withholding Before Reducing Anything

This is where trying to get less withheld most commonly backfires. If you hold two jobs, or you and your spouse both work, each employer runs payroll as if their paycheck is your only income. Each one applies the full standard deduction and the lower brackets to your wages, so combined you’re systematically under-withheld before you make any changes.

Step 2 of the W-4 gives you three ways to fix that, and you should use only one.²

The IRS estimator is the most accurate. Enter every job and income source, and it tells you the exact dollar amount to add to Line 4(c) on the W-4 for your highest-paying job. This handles unequal incomes and mid-year changes better than the other options.
The Step 2(c) checkbox is the simplest. If there are only two jobs with roughly similar pay, check the box on the W-4 for both jobs. Each employer then splits the standard deduction and brackets between the two paychecks. It works well when incomes are close and over-withholds when they aren’t.
The Multiple Jobs Worksheet in the W-4 instructions walks you through a table-based calculation manually.

Using more than one of these at once will double-count the correction. Pick one. If you have more than two jobs or a wide income gap between spouses, use the estimator.

What About Bonuses

Bonuses are usually withheld under the flat rate method: a straight 22% on the bonus, regardless of your actual bracket.⁷ If you’re in the 12% bracket, that’s nearly double what you’ll actually owe on that money. The excess comes back as a refund, but if you’d rather not wait, submit a new W-4 after the bonus is paid and reduce Line 4(c) (or lower another line the estimator identifies) for the remaining paychecks in the year. Run the estimator first so the adjustment matches what was already over-withheld.

When to Redo Your W-4

The IRS recommends reviewing your W-4 every year and after any significant life change.¹ The events that most reliably throw withholding off:

Getting married or divorced, which shifts your filing status, standard deduction, and brackets.
Having or adopting a child, which adds $2,200 in credits to Step 3.
Buying a home, since mortgage interest and property taxes may push you past the standard deduction and make Line 4(b) relevant.
Starting or leaving a second job, which requires a different multi-job calculation.
A large raise or bonus that pushes you into a new bracket mid-year.

The later in the year you adjust, the fewer paychecks there are to absorb the change, so each correction feels bigger. Update as soon as the change happens.

Don’t Cross Into Underpayment Territory

The point of reducing withholding is keeping more of each paycheck without creating a problem in April. The IRS charges an underpayment penalty if you owe more than $1,000 when you file and you haven’t met one of the safe harbor thresholds: you must have paid at least 90% of your current year’s tax or 100% of your prior year’s tax through withholding and estimated payments. If your prior year’s adjusted gross income was over $150,000 ($75,000 if married filing separately), the 100% threshold rises to 110%.⁸

Aim for a small refund rather than a perfect zero. A refund of a few hundred dollars means you were only slightly over-withheld, and it gives you a cushion against an unexpected 1099 or investment gain. Getting aggressive with reductions late in the year is riskier than adjusting early, because fewer paychecks remain to absorb an overshoot.

What the W-4 Cannot Change

The W-4 controls only federal income tax withholding. It has no effect on FICA taxes. Social Security tax is 6.2% of wages up to $184,500 in 2026, and Medicare tax is 1.45% on all wages with no cap.⁹ Higher earners also pay an Additional Medicare Tax of 0.9% on wages above $200,000 for single filers. Nothing on the W-4 changes these rates. Pre-tax benefits, on the other hand, do lower the income subject to FICA in most cases, which is why routing pay through a 401(k), HSA, or FSA is stronger than a W-4 adjustment alone.

State income tax is also separate. Some states accept the federal W-4 for state withholding; many require their own certificate. If you’ve optimized federal withholding but ignored the state form, you may still be significantly over-withheld on the state side. Contact your state tax agency or payroll department for the right form and any state-specific estimator.

Claiming Exempt Is a Narrow Option

If you had zero federal income tax liability last year and expect the same this year, you can claim exemption from federal withholding entirely. For 2026, that means you owed no federal income tax in 2025 and expect to owe none in 2026. Check the “Exempt” box on the W-4, complete Steps 1(a), 1(b), and 5, and skip the rest.²

The exemption expires every year. If you claim it for 2026, submit a new W-4 by February 16, 2027, or your employer reverts to withholding as if you’re a single filer with no adjustments.² Claiming exempt when you don’t qualify carries a $500 civil penalty, and intentionally providing false information on a W-4 can lead to criminal prosecution.⁷ It’s legitimate for students, part-time workers, and low earners, not a way around taxes you actually owe.
