To calculate the total tax liability based on income and deductions, the following formula is used:

\[ \text{Taxable Income} = \text{Annual Income} - \text{Deductions} \]

\[ \text{Total Tax} = \sum_{i=1}^{n} \text{Bracket Rate}_i \times \text{Bracket Income}_i \]

Where:

$\text{Bracket Rate}_i$ = Tax rate for a specific income range.
$\text{Bracket Income}_i$ = Income within the specific tax bracket.

The effective tax rate is calculated as:

\[ \text{Effective Tax Rate} = \frac{\text{Total Tax}}{\text{Taxable Income}} \times 100 \]

Marginal tax rate is determined as the tax rate applied to the next unit of income.

What is a Tax Bracket?

Tax brackets are ranges of income taxed at specific rates. These rates increase progressively as income rises. The idea is to ensure fairness by applying higher rates only to higher income portions, not the entire income.
