The calculation of income tax depends on various factors such as your actual income, tax residency status of the individual, and deductions and offsets that you are eligible for. In general, the following steps can be followed to calculate your income tax:

  • Determine your taxable income:

This includes all sources of income such as salary, business income, rental income, capital gains, etc. Certain deductions and exemptions are allowed to be subtracted from your taxable income, such as contributions to a pension plan, medical expenses, and others.

  • Determine your tax residency status:

This will determine which tax laws and tax rates apply to you. For example, if you are a resident of the United States, you will be taxed on your worldwide income, whereas, if you are a non-resident, you will be taxed only on your income earned within the United States.

  • Look up the tax brackets and tax rates:

Tax brackets and tax rates vary depending on your taxable income and tax residency status. The tax brackets define the range of income that is subject to a specific tax rate. In the United States, for example, there are seven tax brackets with tax rates ranging from 10% to 37%.

  • Calculate your taxes owed:

To calculate your taxes owed, multiply your taxable income by the applicable tax rate. Then, subtract any tax credits or deductions that you are eligible for.
