Where Stub44 wins

The tax math is spelled out. Income Ultra says it will “factor in taxes and deductions to see your real take-home pay,” but its listing does not say how. It does not state whether it computes federal or state income tax, handles Social Security and Medicare, or applies a rate you enter. Stub44 lists federal and state income tax for all 50 states plus DC, Social Security with year-to-date wage-base capping, Medicare and the additional Medicare surtax, W-4 inputs from the post-2020 and pre-2020 forms, and five filing statuses.

Deductions by name. Income Ultra’s listing mentions deductions only in general terms. Stub44 separates pre-tax retirement plans like a traditional 401(k), 403(b), or 457(b), FICA-exempt HSA and FSA money, Roth contributions, and garnishments for child support, IRS levies, and creditors. It also itemizes state payroll items such as CA SDI and NY PFL.
