Attribution policy
Embeds are licensed under MIT (script) + CC0 1.0 (data). This means you can use them commercially, but attribution is required. Removing the SalaryLabs branding or canonical link from the embed footer is a license violation.
The embed iframe includes a small footer with the SalaryLabs name and a link back to salarylabs.site. This footer must remain visible. You may style the iframe border and background, but you may not hide or obscure the attribution.
See the full attribution policyfor details on what is required, what is allowed, and what triggers a license violation.
FAQ
Do I need an API key?
No. The calculator runs entirely in the browser via iframe. No API key, no server, no configuration. Just copy the iframe snippet and paste it into your HTML.
Are the calculations accurate for my state?
Federal tax, FICA, and SSA calculations use 2026 IRS and SSA figures and apply to all 50 states. State income tax rates are parameterized — enter your state's rate manually. Nine states (AK, FL, NV, NH, SD, TN, TX, WA, WY) have no state income tax.
Can I customize the calculator inputs or colors?
The iframe embeds the canonical calculator exactly as it appears on salarylabs.site. You can control the iframe dimensions, border, and background via CSS on your end. Customizing the internal inputs or colors requires the full integration via the API, not the embed.
Does the embed track users on my site?
The iframe loads from salarylabs.site and is subject to salarylabs.site's privacy policy. It does not set third-party cookies or read your site's DOM. It receives your site's referer header only in the standard browser way, which we use to detect whether the visitor came from a known HR, developer, or publisher context.
What happens when tax rates change?
SalaryLabs updates its canonical data weekly via a Cloudflare Worker that monitors IRS, BLS, SSA, and DOL sources. When the IRS publishes new brackets or the SSA updates the wage base, the next Monday cron triggers a rebuild. The embed iframe always loads the latest published version — no action needed on your end.
Can I use these in a commercial product?
Yes, under the MIT license. Commercial use is allowed. The only requirement is visible attribution (the embed footer). If you need a white-label version without attribution, contact us.
I need more customization — can I call the API directly?
Yes. The /developers/ page documents the REST API at POST /api/v1/calculate with 16 tools, plus OpenAPI spec, Python client, and JavaScript SDK. The API is free for reasonable use with attribution.
