Methodology & Source
Oklahoma state tax figures sourced from Oklahoma Tax Commission (https://oklahoma.gov/tax.html), citing Okla. Stat. tit. 68 § 2355. Federal brackets, standard deductions (single/MFJ/HoH), and FICA constants sourced from the IRS (Revenue Procedure 2025-32; married-filing-jointly Additional Medicare threshold of $250,000 is a separate, unindexed statutory figure). Oklahoma's married-filing-jointly and head-of-household figures are not yet independently verified and currently fall back to single-filer brackets — see the caveat in the formula section above.
Bonus federal withholding uses the flat supplemental-wage rate (22%, 37% above $1,000,000 cumulative supplemental wages/year), per IRS Publication 15 (Circular E), Employer's Tax Guide, 2026 edition — the alternative "aggregate method" is not modeled.
This is an estimate based on standard single-filer federal, FICA, and OK state calculations. Actual withholding may differ based on your W-4 elections, pre-tax deductions, and other factors.
