PayStubCheck tests only what the figures you supply can genuinely support. Missing payroll facts are never quietly filled in just to produce an answer.
What each result means
The amount on the stub matches an independent recalculation within that check’s stated tolerance.
The math doesn’t line up, or the figures relate in an unusual way. The result shows what differs — it never calls a document fake or fraudulent.
The calculation needs information you didn’t provide. PayStubCheck never assumes missing W-4, TD1, age or election, taxable-wage, or deduction-treatment facts.
The calculation sits outside current Pay Stub Review coverage, or the relevant calculation module can’t work out the amount on its own from what was entered.
Three kinds of review
- Quick Check: straight gross-to-net arithmetic, done entirely in your browser.
- Detailed Review: arithmetic reconciliation in your browser. Statutory and tax review is not offered right now, and no statutory request is ever sent while that is the case.
- Compare Pay Stubs: year-to-date continuity across two or three statements, in your browser only; the firmer change equations switch on only once you confirm the continuity conditions.
Which way year-to-date figures run
Pay stubs usually print year-to-date figures that already include the current period, yet some payroll formulas need the figure from before the current period to apply yearly wage bases and contribution maximums. Where a calculation module specifically needs that prior figure, PayStubCheck works it out as:
Prior year to date = year to date on the stub − this period’s amountIf the result is negative by more than the rounding tolerance, any statutory check that depends on it is skipped.
How rounding tolerance works
No one tolerance fits every check. Sums of displayed values, hours × rate, rebuilt totals, and statutory formulas each use their own stated tolerance, and exact statutory methods keep their own required rounding. That is why a result can be marked within rounding tolerance instead of being flagged as an unexplained gap.
Which dates the rules cover
The rule data loaded here covers January 1 through December 31, 2026. Having that data does not mean tax is calculated or confirmed. Statutory and tax review is not offered for any date or location right now. Arithmetic and continuity checks are still available; statutory amounts are marked Not evaluated.
Record of changes: Meaningful changes to rules, caps, source coverage, year-to-date handling, tolerances, and how calculations behave are logged on the corrections and updates page.
How your figures are handled
In all three review types, the arithmetic runs in your browser and the payroll figures you type are not sent to PayStubCheck. Because statutory and tax review is not offered, Detailed Review never sends a statutory calculation request. Payroll figures are not saved as review records.
U.S. coverage
This table is built from the same federal and state source register and calculation modules the review relies on. Technical method codes are turned into plain-language labels here, with the original code still available for anyone who wants to audit it.

Canadian coverage
The Canadian path relies on a versioned calculation module and a register of official sources. Québec keeps its own contribution tracks: QPP, QPP2, reduced-rate EI, and QPIP are each assessed separately when enough detail is entered.

Coverage labels, explained
The calculation follows an official formula, elected rate, or statutory method that can be reproduced directly once the required details are entered.
The calculation is built from current official withholding tables, formulas, or agency guidance and may need inputs specific to the jurisdiction.
The jurisdiction has no state-level employee income-tax withholding of the kind being reviewed. Other payroll obligations may still apply.
The Canadian calculation path runs on a versioned calculation module tied to a register of CRA and Revenu Québec sources.

Known limits
- Figures that add up are not a finding that a document is genuine.
- Pay Stub Review never scores applicants or recommends approving or declining anyone.
- Countries and currencies outside coverage get arithmetic checks only.
- Canadian federal and provincial income-tax withholding is only recalculated when every detail the official formula needs can be entered without assumptions; until then, those parts may show Unable to determine.
- Off-cycle checks, corrections, bonuses, and payroll-system changes can legitimately break simple year-to-date continuity across several stubs.
