Calculate Income Tax Based on Salary Brackets

Program Overview

This Python program reads an employee’s monthly salary and calculates the income tax based on a progressive tax table.
The tax rate is determined by the salary range according to the following table:

Tax Table:

From	To	Tax Rate
0	483,000	0%
483,001	965,000	10%
965,001	1,448,000	15%
1,448,001	1,930,000	20%
1,930,001	∞	25%

Python Code:

def calculate_tax(salary: int) -> float:
    if salary <= 483000:
        rate = 0
    elif salary <= 965000:
        rate = 0.10
    elif salary <= 1448000:
        rate = 0.15
    elif salary <= 1930000:
        rate = 0.20
    else:
        rate = 0.25
    return salary * rate

# Read salary from user
salary = int(input("Enter monthly salary (in Rials): "))
tax = calculate_tax(salary)
print(f"Calculated tax: {tax:,.0f} Rials")

Sample Output (input: 1,500,000 Rials):

Calculated tax: 300,000 Rials
