PayStubCheck · Research standards
How PayStubCheck builds public wage-statement research, separates legal-source findings from document-tool calculations, and communicates uncertainty without overstating what the service can verify.
State wage-statement rules and tax calculations are different questions. Our public materials keep those subjects separate and identify where a finding comes from.
For state wage-statement research, we prioritize current statutes, regulations, state labor departments, revenue departments, and other government sources. Commercial summary charts are not treated as controlling authority. Each jurisdiction page identifies the sources used and the date of the latest review.
If a reviewed source does not establish a detail clearly, the public page says so or directs the reader to current agency guidance. We do not invent a legal or payroll detail simply to make every state page look identical.
A state requirement governing what an employer places on a wage statement is different from income-tax withholding. State pages separate statement content, delivery, retention, and tax references. Calculations shown by document tools should be treated according to the product's stated scope and verified against current official instructions when accuracy is legally or financially consequential.
Source-backed research pages carry review dates. Material changes should update the affected page, the downloadable dataset where applicable, and the sitemap modification date. See Corrections & Updates for the public correction process.
For 2026 U.S. paystub products, browser figures are previews. Checkout and final PDF generation recalculate from validated payroll facts with versioned federal, FICA, state, local-review, statutory-program, deduction, supplemental-wage, and YTD rules. Unsupported or unresolved scenarios stop before purchase instead of silently substituting an estimate.
The public U.S. database includes all 50 states plus Washington, DC, with classification, scope, required statement content, delivery notes, retention information, official citations, and review dates.
