“My wife and I just moved to the US and started working (she makes $300k, I make $70k). How should we fill out our W-4s? Is it better to select 'Married filing separately' on the W-4 but then file our actual taxes jointly, or should we select 'Married filing jointly' even if it means a bigger tax deduction per pay period? We have no dependents or other income.”
The W-4 controls —money prepaid from each paycheck—not the filing-status choice you make on your later tax return. Withholding more changes your take-home pay and possible refund or balance due; it is not an extra tax deduction [3][6].
Because you just moved, the correct W-4 route first depends on whether each of you is a when completing the form.
If you both are resident aliens and expect to file jointly, select “Married filing jointly” in Step 1(c) on both W-4s. Because you have two jobs and started during 2026, use the IRS estimator—the form calls it the most accurate Step 2 method—and give its generated W-4s to payroll [1][3].
A must select “Single or Married filing separately” regardless of marriage, must not count the spouse’s job in Step 2, must not use the estimator, and must write “nonresident alien” or “NRA” below Step 4(c) [4]. At return time, a couple who are both residents by year-end may elect full-year resident treatment; one resident and one nonresident spouse may also elect resident treatment. Either election requires a joint return for that year and includes worldwide income; if both remain nonresidents at year-end, they generally cannot file jointly [5].
For resident spouses planning a joint return, selecting “Single or Married filing separately” is not the recommended way to solve two-earner withholding. Form W-4 is a withholding certificate rather than your tax return, so the box does not itself force a separate return, but it makes payroll use the wrong anticipated filing-status assumptions; use “Married filing jointly” plus the estimator or Step 2(b) instead [1].
This answer covers federal Form W-4 withholding; your eventual 2026 return treatment depends on your year-end tax-residency facts.
These steps choose the correct residency branch first, then produce and submit accurate federal withholding certificates.
Before completing either W-4
Identify your federal tax-residency branch
A person generally is a resident alien after meeting the green-card test or substantial-presence test; someone meeting neither is generally a nonresident alien. Use the resident steps below only if resident treatment applies when completing the form; otherwise use the Notice 1392 step [4].
Requisitos
Resident branch — preferred
Run the IRS estimator for both resident spouses
Open https://www.irs.gov/individuals/tax-withholding-estimator and enter both jobs as one married-filing-jointly household. Enter no dependents and no other income based on your facts; if you have deductions beyond the standard deduction, enter those when asked. Download both completed W-4s produced by the estimator [3].
Requisitos
Resident branch — less accurate midyear
Use the 2026 worksheet only as a manual fallback
On both forms select “Married filing jointly” in Step 1(c), and do not check Step 2(c). Complete the Step 2(b) worksheet once for your wife’s higher-paying job. The $300,000/$70,000 wage ranges produce $13,780 annually; enter in her Step 4(c) $265 weekly, $530 biweekly, $574.17 semimonthly, or $1,148.33 monthly. Leave the husband’s Step 4(c) blank, leave Step 3 blank because you have no dependents, and leave Steps 4(a)–(b) blank if you have no other income or deductions. Because you started after January, prefer the estimator rather than this benchmark [1][2].
Requisitos
Nonresident branch
Follow Notice 1392 if either spouse is nonresident
Each nonresident spouse selects “Single or Married filing separately” in Step 1(c), ignores the other spouse’s job in Step 2, leaves Step 3 blank because there are no dependents, leaves Steps 4(a)–(b) blank if there is no applicable income or deduction, writes “nonresident alien” or “NRA” below Step 4(c), signs Step 5, and gives the form to the employer. Do not use the estimator. To claim a treaty withholding exemption, Notice 1392 says to give Form 8233 to the withholding agent instead of claiming it on Form W-4 [4].
Requisitos
As soon as the forms are ready
Give the signed forms to payroll and recheck
Give each W-4 to the employer or its payroll or human-resources system—not to the IRS. Compare the first updated paystubs with the estimator result, file another W-4 after a material change, and check withholding again in January; the IRS specifically recommends a January review [3].

You are not the first to go through this. Here is how it went for others who asked the same thing.
u/FoodCourtBailiffr/tax28 jul 2026
This answer is based on the 2026 IRS Form W-4, the IRS Tax Withholding Estimator, Notice 1392, and IRS Publications 505 and 519.
Form W-4 (2026)
The form says a married two-earner household must address both jobs and identifies the estimator or worksheet as the appropriate methods.
Steps 1(c)–2, page 1
Complete this step if you (1) hold more than one job at a time, or (2) are married filing jointly and your spouse also works. Do only one of the following. (a) Use the estimator at www.irs.gov/W4App for the most accurate withholding for this step (and Steps 3–4). This option is generally more accurate than Step 2(b) if pay at the lower paying job is more than half of the pay at the higher paying job. Otherwise, Step 2(b) is more accurate.
Form W-4 (2026)
The worksheet produces a $13,780 annual adjustment for the stated wage ranges and requires conversion to a per-pay-period Step 4(c) amount.
Multiple Jobs Worksheet and tables, pages 3 and 5
Enter the number of pay periods per year for the highest paying job. For example, if that job pays weekly, enter 52; if it pays every other week, enter 26; if it pays monthly, enter 12, etc. Divide the annual amount on line 1 or line 2c by the number of pay periods on line 3. $240,000 - 319,999 2,040 4,440 6,840 8,610 10,010 11,380 12,580 13,780 14,980 16,180 17,380 18,580
IRS Tax Withholding Estimator
The IRS estimator can generate W-4s for resident employees but expressly excludes nonresident aliens.
Use this tool to estimate the correct amount of tax your employer (W-2) or pension provider should withhold each year. You can download a completed Form W-4 or Form W-4P and give it to your employer or pension provider. You can’t use this tool if you have nonresident status for U.S. tax purposes.
Notice 1392
Notice 1392 supplies the controlling W-4 instructions for a nonresident alien and identifies the treaty-exemption form.
Steps 1(c), 2 and 4(c)
Step 1(c): Personal Information. Check the Single or Married filing separately box regardless of your actual marital status. Do not account for your spouse's job because nonresident aliens may not file jointly. Nonresident aliens should not use the Tax Withholding Estimator. Step 4(c). Write “nonresident alien” or “NRA” in the space below Step 4(c). If you are claiming a tax treaty withholding exemption, do not complete Form W-4. Instead, complete Form 8233, Exemption from Withholding on Compensation for Independent (and Certain Dependent) Personal Services of a Nonresident Alien Individual, and give it to each withholding agent from whom amounts will be received.
Publication 519 (2025)
Publication 519 explains when newly arrived or mixed-residency spouses may elect joint, full-year resident treatment and when joint filing is unavailable.
Chapter 1, pages 10–12; Chapter 5, page 35
This includes situations in which both you and your spouse were nonresident aliens at the beginning of the tax year and both of you are resident aliens at the end of the tax year. You and your spouse are taxed on worldwide income. You and your spouse must file a joint return for the year of the choice. If, at the end of your tax year, you are married and one spouse is a U.S. citizen or a resident alien and the other spouse is a nonresident alien, you can choose to treat the nonresident spouse as a U.S. resident. A nonresident alien generally cannot file as married filing jointly.
Publication 505 (2026)
A new arrival cannot rely solely on having had no prior U.S. tax to obtain the prior-year estimated-tax exception.
Chapter 2, page 20
You don’t have to pay estimated tax for 2026 if you meet all three of the following conditions. • You had no tax liability for 2025. • You were a U.S. citizen or resident alien for the whole year. • Your 2025 tax year covered a 12-month period.
IRS Topic No. 560
The individual and employer thresholds can leave this couple with a small Additional Medicare Tax withholding gap if they earn the stated amounts during 2026.
A 0.9% Additional Medicare tax applies to Medicare wages, self-employment income, and railroad retirement (RRTA) compensation that exceed the following threshold amounts based on filing status: $250,000 for married filing jointly; An employer is responsible for withholding the Additional Medicare tax from wages or railroad retirement (RRTA) compensation it pays to an employee in excess of $200,000 in a calendar year, without regard to filing status. Some taxpayers may need to request that their employer withhold an additional amount of income tax withholding on Form W-4, Employee’s Withholding Certificate, or make estimated tax payments to account for their Additional Medicare tax liability.
These are the official IRS rules published for the cited years and update dates; tax rules and forms can change.
