How to read this coverage map
A public local tool is an implemented calculator with a locale-specific methodology. A public local guide explains an implemented surface. Global support is market-neutral decision help. Official context can identify a boundary without making it a Wage101 feature. Unsupported or deferred means no public local calculator is represented here.
| Surface | Current status | Link treatment |
|---|---|---|
| /en-us/tools/ | Renderable partial local catalog; noindex | Linked and labelled as partial |
| /en-us/blog/ | Indexable with 3 public local companion articles | Linked as the locale guide index |
| /en-us/data/ | No published dataset or source page; route returns 404 | Not linked |
What is implemented now
The exact public set contains 3 local calculators. Each row keeps the calculator and its methodology together; calculation logic, rounding and edge cases remain on those surfaces.
The registered public local companion set contains 3 articles: “US FICA Tax: what the Wage101 calculator includes” (/en-us/blog/us-fica-tax-guide/); “US Tipped Wage: what the Wage101 calculator includes” (/en-us/blog/us-tipped-wage-guide/); “California Overtime Pay: what the Wage101 calculator includes” (/en-us/blog/us-california-overtime-pay-guide/). Each article stays paired with its exact implemented calculator boundary.
| Public local tool | Tool route | Methodology route | Implemented boundary |
|---|---|---|---|
| US FICA Tax Calculator | /en-us/tools/us-fica-tax/ | /en-us/tools/us-fica-tax/methodology/ | Employee Social Security, Medicare and Additional Medicare withholding within the registered 2026 boundary. |
| Federal Tipped Wage Shortfall Calculator | /en-us/tools/us-tipped-wage/ | /en-us/tools/us-tipped-wage/methodology/ | Federal FLSA tip-credit shortfall arithmetic only; state and local rules remain outside it. |
| California Daily Overtime Pay Calculator | /en-us/tools/us-california-overtime-pay/ | /en-us/tools/us-california-overtime-pay/methodology/ | California ordinary-workday daily overtime arithmetic for the supported general rule, not every wage order. |
Choose the right path
These are routing checks, not independent calculations. If a required fact is uncertain or a listed exclusion applies, stay with the official source or seek appropriately qualified help instead of stretching a bounded result.
Three non-numeric routing examples
- For FICA, use the FICA companion, calculator and methodology; keep federal income tax outside the result.
- For tipped wages, confirm federal FLSA tip-credit coverage and check state or local rules before using the shortfall tool.
- For California daily overtime, confirm that the supported ordinary-workday boundary fits; otherwise use official DIR guidance.
Official sources and how they are used
Every source below was accessed on 2026-07-28. The freshness note identifies whether it is load-bearing for an implemented tool or context for a deferred boundary. The hub does not reproduce rate tables or turn context-only evidence into a feature.
| Official source | Allowed use | Required caveat |
|---|---|---|
| IRS Publication 15 | Load-bearing 2026 employee FICA rates, wage-base and withholding-trigger evidence. | It does not support federal income-tax, state or local tax, or full take-home claims. |
| US DOL Fact Sheet #15 | Load-bearing federal tipped cash-wage, tip-credit and employer-shortfall evidence. | State and local tipped-wage rules can be more protective and must be checked. |
| California DIR overtime FAQ | Load-bearing general California daily overtime context. | Wage-order, occupation and alternative-workweek exceptions are deferred. |
| US DOL Fact Sheet #23 | Context for the unsupported federal over-40-hours branch. | Wage101 has no public federal FLSA eligibility calculator. |
Global support is not local policy
The Global guides below are market-neutral support only. They can help frame a comparison or organise user-supplied inputs, but they do not validate local United States rules, supply a local legal default or expand the implemented local set.
| Global guide | Route | Scope |
|---|---|---|
| Gross-to-net using your own tax rate guide | /blog/gross-to-net-pay-using-your-tax-rate-guide/ | Global, market-neutral support only |
| Overtime pay using your own rule guide | /blog/overtime-pay-using-your-rule-guide/ | Global, market-neutral support only |
| Tips income guide | /blog/tips-income-guide/ | Global, market-neutral support only |
United States coverage questions
- Is this complete United States pay and employment coverage?
- No. It is an exact map of 3 currently implemented local calculators and their stated boundaries. The exclusions above remain unsupported or deferred.
- Does this hub calculate a pay, tax or entitlement result?
- No. The hub routes readers. Inputs, formulas, evidence, rounding and results remain with each linked calculator and methodology.
- Is a public Wage101 DataHub available for United States?
- No. There is no published en-us dataset or source page, so this hub does not link the current 404 data route.
