Today is the operative word: we check Paycheck Calculator every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

calculate
calculate_take_home_pay
Calculates take-home (net) pay for a US employee in any of the 50 states or DC for tax year 2025 or 2026: federal income tax from the IRS Rev. Proc. 2024-40 / 2025-32 bracket tables with the One Big Beautiful Bill Act standard deduction ($15,750 single for 2025, $16,100 for 2026), Social Security with the wage base ($176,100 in 2025, $184,500 in 2026), Medicare plus the 0.9% Additional Medicare tax, and state income tax. State tax is exact from each state's 2026 schedule for CA, NY, NJ, IL, PA, GA, NC; other states return a labeled effective-rate estimate (method: "estimate"). Handles pre-tax 401(k) (not FICA-exempt) and payroll HSA (FICA-exempt), and Pennsylvania/New Jersey rules that tax 401(k) or HSA money. Returns per-period and annual figures. Local taxes (NYC etc.) are out of scope. Figures copied from irs.gov and state revenue sites in Oct 2026.
compare
compare_states_take_home
Runs the same gross pay through 2 to 10 states (or DC) and ranks them by annual take-home pay for tax year 2025 or 2026, showing state income tax, the method for each state (exact 2026 schedule for CA, NY, NJ, IL, PA, GA, NC; labeled estimate elsewhere; no wage income tax in AK, FL, NV, NH, SD, TN, TX, WA, WY) and how far each trails the best. Federal tax and FICA use the IRS 2025/2026 tables and wage base. Use it for relocation and remote-work offers.
federal
get_federal_tax_brackets
Returns the exact federal income tax brackets (rate, lower and upper bound, tax on lower brackets) and standard deduction for tax year 2025 or 2026 and a filing status, from IRS Rev. Proc. 2024-40 and Rev. Proc. 2025-32, including the One Big Beautiful Bill Act (P.L. 119-21) standard deduction increase for 2025 ($15,750 / $31,500 / $23,625). Also returns the Social Security wage base and Medicare thresholds for that year.
hourly
hourly_to_salary
Converts an hourly wage to weekly, monthly and annual gross pay, with optional weekly overtime hours at a multiplier (1.5 by default). Defaults: 40 hours a week, 52 weeks. Gross pay only; use calculate_take_home_pay for net.
salary
salary_to_hourly
Converts an annual salary to an hourly rate and to weekly, biweekly (26), semimonthly (24) and monthly gross pay. Defaults: 40 hours a week, 52 weeks (2,080 hours). Gross pay only; use calculate_take_home_pay for net.

How MCP servers expose tools in the first place →
Is Paycheck Calculator working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 219 ms. The bar chart above shows every period we have measured.
How do I connect Paycheck Calculator?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Paycheck Calculator need an API key?
No. Paycheck Calculator completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Paycheck Calculator?
It answers our handshake in 219 ms on average, which is faster than 65% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Paycheck Calculator open source?
The code is open source: it is published under the MIT licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at paycheck-calculator-mcp.lipmichal.workers.dev, which runs on its operator's own terms.
