Quarterly Estimated Tax Calculator — Wyoming (2026)
If you earn income in Wyoming without withholding — freelancing, contracting, rentals, dividends — the IRS expects payment four times a year, not once. This calculator turns your expected 2026 net profit into a per-quarter number covering self-employment tax, federal income tax and no state tax, since Wyoming has none. Wyoming does not levy a personal state income tax, so the only mandatory withholding on your earnings is federal income tax plus FICA (Social Security and Medicare).

2026 due dates and safe harbor
Federal estimated payments are due April 15, June 15, September 15 of 2026 and January 15 of 2027. You avoid penalties by paying either 90% of the current year's liability or 100% of last year's (110% if prior-year AGI exceeded $150,000) — the safe-harbor rule.
There is no Wyoming estimated payment to make — the state does not tax personal income, so you only file federally.
Underpayment penalties
The IRS charges interest-style penalties per quarter you fall short, currently around 7–8% annualized. Paying late in the year does not fix an early-quarter shortfall unless you use the annualized income method on Form 2210.
Irregular income is common in energy work around Cheyenne: if Q1 is slow and Q4 is huge, the annualized method usually beats four equal payments.
Paying as a Wyoming taxpayer
Pay federally through IRS Direct Pay or EFTPS — no state portal is needed.
Wyoming has no state income tax. Revenue comes from mineral royalties, a 4% state sales tax (up to 6% with local), and property taxes.
Local and payroll taxes Wyoming adds on top
Wyoming adds no state-mandated employee payroll deduction beyond FICA, so nothing extra is taken from your gross pay at the state level.
Wyoming has no state income tax. Revenue comes from mineral royalties, a 4% state sales tax (up to 6% with local), and property taxes.
Nobody withholds these for you when you are self-employed in Wyoming. Local wage taxes, city business licences and gross-receipts style levies are yours to register for and remit alongside your quarterly federal and state estimates.
Working across a state line from Wyoming
Wyoming has no income-tax reciprocity agreements, so if you live here and work across a state line you generally file a nonresident return in the work state and claim a credit at home to avoid double taxation.
Remote and hybrid work complicates this further: most states tax income where the work is physically performed, so a Cheyenne resident spending part of the year at a client site in Colorado may owe a nonresident return there. Keep a day-count log if you split time between states.
The rest of your Wyoming tax bill
Wyoming charges a 4% state sales tax, homeowners pay an average effective property tax of 0.61% of market value, and the minimum wage in force during 2026 is $7.25 an hour.
County add-ons make about 5.4% the typical combined rate.
Income tax is only one part of a state's take. Wyoming recovers revenue through sales and property tax as well, which is why headline income tax rates alone are a poor guide to how far a salary really goes. With no state income tax, Social Security, pensions, 401(k) and IRA withdrawals are all free of state tax here.
Wyoming vs Colorado on the same salary
On a $90,000 salary, a single filer keeps about $72,145 a year in Wyoming against roughly $68,893 in Colorado — a difference of $3,252, or $271 a month.
Effective combined rates are 19.8% in Wyoming and 23.5% in Colorado. Set that gap against living costs: index 96 here versus 105 there, with property tax at 0.61% and 0.49% respectively.
