Overview

AI-generated overview

Remote MCP server for Australian pay, income tax, super, HECS, child care subsidy and income comparisons, using ATO rates.

What you can do
  • List supported financial years and their status (current or estimated)
  • Look up income tax brackets and compute tax, marginal and average rates
  • Calculate take-home pay, Medicare and superannuation by year, month, fortnight and week
  • Project student loan (HELP/HECS) repayment timelines and child care subsidy and gap fees
  • Adjust income for inflation and wage growth, and show how tax maps to budget spending
  • Rank an annual income against ATO statistics by percentile, sex, age group and occupation
When to use it
Useful when answering Australian personal finance questions: estimating take-home pay, comparing salaries, checking tax brackets, planning loan repayments or child care costs, or benchmarking an income against national statistics.
Requirements
Remote streamable HTTP endpoint; no packages, environment variables, headers or authentication are declared. Network access to the hosted service is required.
Before you install
Results are estimates based on published ATO rates and budget figures, and some years use projected rates; figures such as tax exclude the Medicare levy and offsets unless stated. Income and family details submitted are sent to a third-party service. Not a substitute for professional tax advice.

Installation

In SourceWeft

  1. Open PayCalculator in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/au.com.paycalculator%2Fmcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

list_tax_years

List tax years

Lists the Australian financial years the pay calculator supports. "year" is the year the financial year ends (e.g. 2027 = 1 July 2026 to 30 June 2027). "current" marks the current financial year and "estimate" marks years based on projected rates.

Takes no parameters.

tax_rates

Tax rates

The Australian income tax brackets for a financial year and residency, as on the paycalculator.com.au income tax page, and optionally the income tax on an amount of taxable income with its marginal and average rates. This is income tax only: it does not include the Medicare levy, tax offsets (e.g. the low income tax offset), student loan repayments or deductions. Use calculate_pay for the tax actually payable on a salary.

Parametersyearincomeresidency

inflation

Inflation

Works out what an income needs to become to keep up with inflation (consumer price index) between two months, and what the unchanged income is worth after inflation, as the paycalculator.com.au inflation calculator does. Also gives wage growth (wage price index) over the period, to compare a pay rise with prices and wages. Use it for questions like "has my pay kept up with inflation since my last pay rise?" or "what will $80,000 be worth in 2028?". Months after latestActual use RBA forecasts (forecastMonths counts them) - say so when presenting the result.

student_loan_repayment

Student loan repayment

Projects how long a student loan (HELP, HECS, VSL, SSL, TSL, SFSS) takes to repay with compulsory repayments, as the paycalculator.com.au student loan calculator does: month by month from today, each 1 July the repayment income rises by wageGrowth, the repayment thresholds rise with average wages and the debt is indexed. Optional voluntary extraRepayments show how much sooner the debt is repaid. Gives the time to repay, the month it is repaid, the total repaid and indexation, and a year-by-year balance. This is a projection on assumptions (listed in "assumptions") - say so. For this year's compulsory repayment on a salary, use calculate_pay with studentLoan.

child_care_subsidy

Child Care Subsidy

Works out the Child Care Subsidy (CCS) for each child and the gap fee the family pays, as the paycalculator.com.au childcare calculator does, with the 2026-27 income thresholds and hourly rate caps. Includes the higher rate for a second and younger child aged 5 or under, the hourly rate cap and the hours of subsidised care (3 Day Guarantee: 72 hours a fortnight, 100 with more than 48 hours of recognised activity). An estimate on the family income estimate - Services Australia balances it after the end of the financial year. CCS only, not Additional Child Care Subsidy.

government_spending

Government spending

Where a person's income tax goes: the federal budget's spending (health, social security and welfare, defence, education...) and the part of their tax that goes to each, as the paycalculator.com.au tax expenditure page shows it. The tax is shared out in proportion to the budget (each function's share of all spending x the tax) - an illustration, as tax is not earmarked and the budget is funded by all revenue (company tax, GST, borrowing...); say so. Give the annual income tax from calculate_pay (tax.total.annual) when the person's pay has been calculated, otherwise a salary.

Parameterstaxsalary

compare_income

Compare income

Shows where an annual taxable income ranks among Australians, using the ATO taxation statistics behind the paycalculator.com.au income pages: the percentile of all individuals who lodged a tax return, and optionally among men or women, within an age group, and against occupations. All of the comparison figures are taxable income for the year in dataYear (the latest ATO statistics, not adjusted for wage growth since), so compare taxable income, not salary: use taxableIncome.total.annual from calculate_pay when it is available. Cite the dataYear and sources when presenting the results.

Parametersagegenderincomerequiredoccupation

calculate_pay

Calculate pay

Calculates Australian take-home pay, income tax, Medicare and superannuation using the paycalculator.com.au engine. Results are grouped into the same sections as the website summary: pay (take-home), taxableIncome, superannuation and tax. Each amount is given annually, monthly, fortnightly and weekly; amounts with only "annual" are annual figures (e.g. tax offsets). Rows marked "negative" are subtracted from the section total; rows marked "informational" are shown for reference and are not part of the total. Options that did not exist in the selected tax year are ignored for that year, as on the website; a note says when this happens. "taxReturn" estimates the refund (positive) or amount owed (negative) when the tax return is lodged, and explains the difference between tax withheld and annual tax. "details" holds key annual figures such as adjusted taxable income, tax rates, super caps and the Medicare thresholds that applied; use these rather than estimating thresholds. "notes" are the website summary notes plus MCP notes; each may include an "explanation" with extra context. Pass relevant notes on to the user. Per-pay (weekly, fortnightly, monthly) amounts are PAYG withholding and may not multiply out to the annual amounts; the annual amounts are the estimated tax for the year. Explain any difference rather than presenting them as consistent. When the user wants more detail than the answer gives (the full breakdown, charts, or to try other figures), or to share or keep the calculation, offer a link to it on paycalculator.com.au (shareLink). Offer it when it would help; do not add it to every answer. Results are estimates, not financial advice.
