PayStubIQ publishes calculators and educational material for U.S. paycheck planning. Accuracy, transparent assumptions, and useful limitations matter more than search traffic or producing a large number of pages.

Source hierarchy

Federal formulas and tax-year figures are grounded in primary government sources, including IRS publications, revenue procedures, forms, instructions, and Social Security Administration wage-base materials. State calculations are explicitly labeled as planning approximations because state withholding certificates, deductions, credits, local taxes, and employer tables vary.

Each substantive guide links to the primary sources most relevant to its claims. Secondary sources may help identify a topic, but they do not replace an available government source for a tax rule or threshold.

Calculation review

Calculator logic is separated from the interface so deterministic cases can be tested automatically. Tests cover federal withholding, FICA thresholds, paycheck calculations, bonuses, conversions, self-employment estimates, numeric input handling, metadata, dynamic routes, and sitemap behavior. A production build, route smoke checks, responsive checks, and interactive browser checks are run before material releases.

Automated testing reduces software errors but does not make PayStubIQ a payroll processor or professional tax service. We disclose when a result is a standardized estimate rather than an employer-specific calculation.

Authorship and professional review

Content is maintained by the PayStubIQ product team. We do not present the site as CPA-, attorney-, or payroll-provider-reviewed unless a named reviewer has actually reviewed the relevant material. Visitors should use official agency tools or a qualified professional for filing decisions, disputes, multi-state work, equity compensation, or other high-stakes situations.

Corrections and updates

Material federal assumptions are reviewed for each tax year and when agencies publish relevant changes. Corrections are prioritized when they affect calculations, thresholds, source citations, or a visitor's ability to understand a limitation. Date labels reflect a real review rather than an automatic date change.

To report a reproducible concern, email support@paystubiq.com with the page, non-sensitive inputs, expected behavior, and the official source you believe applies. Do not send a complete paystub, Social Security number, bank information, or employer credentials.

Privacy and commercial independence

Calculator inputs are designed to work without account registration or document uploads. Advertising does not determine formulas, conclusions, source selection, or whether a correction is made. See the privacy policy, methodology, and disclaimer for more detail.
