The Retrieve US Tax Filing Information API provides structured access to US income tax rates and brackets, organized by tax year and taxpayer type. The API delivers the income ranges that correspond to each federal rate, allowing you to accurately identify which percentage applies to each segment of individual income, based on the taxpayer's marital status.
It is designed for tax calculation applications, financial planning, accounting software, and services that need to estimate federal taxes automatically and accurately. The data is segmented into brackets or progressive scales, allowing the current tax structure to be applied to income simulations or economic analyses.
In addition to being useful for developers who integrate tax logic into their platforms, the API can also be used by tax advisors, personal finance mobile applications, and any tool that provides net income or withholding projections. The JSON structure facilitates integration into all types of systems, and because it is organized by year, it allows access to both current and historical information.
This API simplifies the complex calculations of the US progressive tax system, providing clarity on how much tax is paid at each income level and helping to ensure accuracy and regulatory compliance.
The GET Income Taxes endpoint returns federal income tax brackets and rates for a specified tax year and taxpayer status. This includes income ranges corresponding to each tax rate, allowing users to determine applicable tax percentages for different income segments.
The response data typically includes fields such as "year," "taxpayer_status," "brackets," and "rates." Each bracket contains income ranges and the corresponding tax rate, providing a clear view of the progressive tax structure.
The response data is structured in JSON format, organized by year and taxpayer status. Each tax bracket is listed with its respective income range and tax rate, making it easy to parse and utilize in applications.
The endpoint requires a "year" parameter to specify the tax year. An optional parameter allows users to request federal tax information only by setting it to true, excluding state and provincial data.
The endpoint provides information on federal income tax brackets, rates, and income ranges for various taxpayer statuses, such as single, married filing jointly, and head of household, for both current and historical years.
Data accuracy is maintained by sourcing information from official IRS publications and guidelines. Regular updates ensure that the API reflects the most current tax laws and rates, providing reliable data for users.
Typical use cases include tax calculation applications, financial planning tools, accounting software, and services that estimate federal taxes. Users can leverage the data for income simulations and compliance checks.
Users can utilize the returned data by integrating it into their applications to calculate estimated taxes based on user income. By referencing the income ranges and rates, developers can create accurate tax calculators and financial planning tools.
