calculate_mlb_taxCalculate MLB taxInspect

Calculate professional-athlete tax for one MLB season with the Jock Taxes engine. Ask the user for a missing team or salary. Do not invent team codes, seasons, salaries, or filing status.

Send base_salary plus optional signing_bonus and performance_bonus to match the site Salary + Bonuses form. Do not send salary together with base_salary or a bonus. exempt_signing_bonus_from_jock_tax defaults to true for a split, so the signing bonus is taxed only in the player's domicile. performance_bonus is included only when include_performance_bonus_in_jock_tax is true. art_xvi4_inducement_sb applies to an exempt signing bonus paid by a Canadian club to a U.S. resident. Present the result as a calculation, not as tax or legal advice. Required before this call: team, and salary or base_salary.
