calculate_us_state_tax

Calculate US state income tax for any supported state. Input your annual income and select a state to receive the tax amount and effective tax rate. Plan your paycheck across different states.

Instructions

Compute US state income tax for a chosen state. Use for paycheck planning across states. Inputs: state, gross income, filing status. Returns state tax due and effective rate. See list_bundles for related 'finance-us' calculators.

incomeYesAnnual taxable income in USD

Output Schema

TableJSON Schema
NameRequiredDescriptionDefault
resultNoComputed result. Object whose fields depend on the tool (e.g. {tax, marginal_rate, brackets} for tax tools, {volume_l, gallons} for volume tools).
formulaNoHuman-readable formula or method used (e.g. "I=P·r·t", "Magnus formula").
sourceNoAuthoritative source for the rule or formula (e.g. "Article 197 CGI", "NF DTU 21").
reference_urlNoLink to a calcul2 page documenting the calculation in detail.
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided. The description states it returns state tax due and effective rate, implying a read-only calculation. However, it does not explicitly disclose that it has no side effects or require special permissions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a short paragraph that includes some unnecessary detail (list of inputs) and an inaccuracy. It could be more concise and aligned with the schema.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description mentions inputs and outputs, but given the tool has an output schema, the return value explanation is redundant. It lacks information about edge cases or supported states beyond the enum list.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema covers both parameters with descriptions (100% coverage). The description adds 'gross income' but also mentions 'filing status' which is not a parameter, creating inconsistency. This confusion reduces the value added beyond schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it computes US state income tax for a chosen state and mentions use case (paycheck planning). However, it lists 'filing status' as an input which is not in the schema, causing confusion and reducing clarity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description says 'Use for paycheck planning across states' and references 'finance-us' bundle via list_bundles. It provides some context but does not explicitly state when not to use or distinguish from sibling tax calculators.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
