Understanding how to calculate your pretax income is an essential aspect of managing your personal and business finances. Pretax income refers to the amount of money you make before taxes and deductions are applied. It’s a critical figure to know for budget and tax planning purposes. In this article, we’ll explore the steps to accurately calculate pretax income.

Step 1: Determine Gross Income

The first step in calculating pretax income is determining your gross income. For individuals, this includes all sources of earned and unearned income, such as wages, salaries, commissions, bonuses, rental income, interest and dividend earnings, alimony or child support received, and any other sources.
For businesses, gross income is calculated as total revenue minus the cost of goods sold (COGS). It’s essential to have accurate records of all financial transactions and revenue streams.

Step 2: Subtract Deductions

Once you have determined your gross income, the next step is to subtract any applicable deductions. Deductions are expenses incurred during the tax year that can be used to reduce taxable income.

For individuals:

– Standard or itemized deductions: You can either choose the standard deduction (a fixed amount based on your tax filing status) or itemized deductions (a detailed list of qualifying expenses). Common itemized deductions include mortgage interest, charitable donations, property taxes, and unreimbursed employee expenses.

– Personal exemptions: Before the Tax Cuts and Jobs Act of 2017 (TCJA), each taxpayer had a personal exemption for themselves and their dependents which reduced taxable income. While personal exemptions were suspended by the TCJA till 2025, some states may still allow you to claim a state-level exemption.

For businesses:

– Operating Expenses: Subtract all operating costs from gross income. These expenses include salaries, rent, office supplies, utilities, insurance premiums, and depreciation.

– Non-operating Expenses: Non-operating expenses, which are not directly tied to everyday business operations but impact the bottom line, such as interest payments on loans and investment losses, must also be deducted.

Step 3: Calculate Pretax Income

After you have determined your gross income and subtracted the deductions, you will be left with your pretax income. This critical financial figure can be used to make informed decisions about budgeting, forecasting, and tax planning.

Many online calculators and tools can help simplify the pretax income calculation process. However, a comprehensive understanding of your financial streams and expenses is essential for accurate measurement. Consulting with a licensed financial professional or certified public accountant (CPA) is recommended if you’re unsure about any aspect of your pretax income calculations.
