Wyoming Paycheck Calculator (2026)

Estimate your Wyoming take-home pay after federal income tax and FICA. Wyoming has no personal income tax, deterred since 1974 by a constitutional requirement that any income tax credit taxpayers for sales, use, and property taxes already paid.

How this calculator works

Wyoming has no state tax on wages or personal income today, so your paycheck deductions are federal income tax and FICA only. This calculator takes your gross pay, subtracts any pre-tax 401(k) and health-insurance deductions, computes federal income tax and FICA on what’s left, and divides the year’s total by your number of pay periods to estimate what lands in your account each paycheck.

The formula

grossAnnual        = salary, or hourlyRate × hoursPerWeek × 52
ficaWages          = grossAnnual − pretaxHealth        (401(k) does NOT reduce FICA wages)
fedTaxableWages    = grossAnnual − pretaxHealth − 401(k) contribution
taxableIncome      = max(0, fedTaxableWages − standardDeduction)

FICA   = 6.2% of ficaWages (up to the $184,500 wage base)
     + 1.45% of ficaWages (no cap)
     + 0.9% of ficaWages over $200,000

federalTax = 2026 bracket engine applied to taxableIncome
stateTax   = $0 (Wyoming Constitution Article 15, Section 18 makes any income tax credit-neutral against sales, use, and property taxes already paid, so none has been enacted)

net = grossAnnual − pretaxHealth − 401(k) − FICA − federalTax − stateTax − postTaxDeductions
netPerPaycheck = net / payPeriodsPerYear

Worked example

A single filer earning $60,000/year, paid biweekly, with no 401(k) or extra deductions:

  • FICA: 7.65% × $60,000 = $4,590.00/year ($3,720 Social Security + $870 Medicare)
  • Taxable income: $60,000 − $16,100 standard deduction = $43,900 → federal tax = $5,020.00/year
  • Net pay: $60,000 − $4,590 − $5,020 = $50,390.00/year, or $1,938.08 per biweekly paycheck

This is the same arithmetic as our Texas, Florida, Washington, Tennessee, Nevada, New Hampshire, Alaska, and South Dakota calculators’ worked examples, since all nine states now have $0 state tax on wages; only the state-specific content differs. Wyoming’s road to $0 is unlike any of the other eight: the state constitution doesn’t ban an income tax by name, and Wyoming never enacted one to begin with. Instead, a 1973 legislative resolution, ratified by voters in 1974, added a rule that any income tax must credit taxpayers for the sales, use, and property taxes they already paid that year, a requirement large enough to erase most of the revenue such a tax could raise. Nothing in the arithmetic above changes because of that history; it only explains why the state-tax line reads $0.

Frequently asked questions (FAQ)

Does Wyoming have a state income tax on wages or salary?

No. Wyoming has never had a personal income tax on wages or salary, and none is on the table today. A 1974 constitutional provision makes any future income tax financially self-defeating rather than illegal, and no legislature has enacted one since that provision was ratified.

Does the Wyoming Constitution actually ban an income tax?

No, and this is a common misreading. Article 15, Section 18 does not name-ban income taxes. It says any income tax must give taxpayers full credit against that liability for all sales, use, and ad valorem (property) taxes paid the same year, a credit large enough to wipe out most or all of what the tax would raise.

Where did Article 15, Section 18 come from?

State Rep. Nels Smith, then Wyoming House Speaker, sponsored House Joint Resolution 12 in the 1973 legislative session. It cleared the required two-thirds vote of both chambers and went to voters, who ratified it at the November 5, 1974 general election, adding it as Article 15, Section 18.

Could the Wyoming legislature pass an income tax if it wanted to?

Legally, yes, nothing in Article 15, Section 18 forbids the legislature from passing one. Practically, the mandatory sales/use/ad-valorem tax credit would offset most or all of the revenue, since Wyoming relies heavily on those taxes, which is why no legislature has found it worth doing since 1974.

What is FICA?

FICA is the combined 7.65% Social Security (6.2%) and Medicare (1.45%) tax withheld from your paycheck, matched by your employer. Social Security stops once your wages hit the annual wage base ($184,500 for 2026); Medicare has no cap and adds an extra 0.9% above $200,000.

How does contributing to a 401(k) change my take-home pay?

A traditional 401(k) contribution lowers the wages your federal income tax is calculated on, so it shaves a bit off your income tax bill, but it does not reduce your Social Security or Medicare wages, since those are calculated before the 401(k) deduction.

Why doesn't my calculated net pay match what shows up in my actual paycheck?

This calculator estimates your annual tax liability and divides it evenly across your pay periods. Your actual employer withholds federal tax per paycheck using IRS withholding tables, which can differ slightly period-to-period; the two methods land close together but rarely to the exact cent.
