How Do You Find Your Taxable Income

Taxable income is the amount of income subject to taxation. To calculate your taxable income, start with your gross income (total income before deductions). Then subtract allowable deductions and exemptions. Deductions are expenses that reduce your taxable income, such as mortgage interest, charitable contributions, and business expenses. Exemptions are fixed amounts that reduce your taxable income regardless of expenses, such as the personal exemption and dependent exemptions. The resulting amount is your taxable income, which is used to determine your tax liability.

Identifying Taxable Sources

Determining your taxable income is crucial for filing accurate tax returns. Here’s a comprehensive guide to help you identify and calculate your taxable sources:

Identifying Taxable Sources

  • **Wages, Salaries, and Tips:** Income earned from employment, including overtime pay, bonuses, commissions, tips, and other compensation.
  • **Self-Employment Income:** Profits or losses from operating a business or freelance work.
  • **Investments:** Capital gains, dividends, interest earned on investments such as stocks, bonds, and mutual funds.
  • **Rental Income:** Net income from rental properties, after deducting expenses.
  • **Royalties:** Payments for the use of intellectual property, such as patents, trademarks, or copyrights.
  • **Alimony and Child Support:** Payments received as alimony or child support are taxable.
  • **Pensions and Annuities:** Payments received from pensions, annuities, and retirement savings accounts.
  • **Social Security Benefits:** A portion of Social Security benefits may be taxable, depending on your income and filing status.
  • **Unemployment Compensation:** Unemployment benefits received are generally taxable.
  • **Gambling Winnings:** Winnings from gambling activities, such as lottery, casinos, and sports betting.

Calculating Taxable Income

Once you have identified your taxable sources, you need to calculate your total taxable income. This is done by subtracting certain deductions and exemptions from your gross income.

Your taxable income is the amount of income subject to taxation. Understanding how to identify and calculate your taxable sources is essential for accurate tax filing and maximizing tax savings.

Calculating Deductions and Exemptions

To determine your taxable income, you must first calculate your deductions and exemptions. Deductions are expenses that you can subtract from your gross income to reduce your taxable income. Exemptions are a specific amount of income that you can exclude from taxation.

Calculating Deductions

  • Standard Deduction: You can choose to take the standard deduction, which is a fixed amount that varies depending on your filing status. For 2023, the standard deduction amounts are:
    • Single: $13,850
    • Married filing jointly: $27,700
    • Married filing separately: $13,850
    • Head of household: $20,800
  • Itemized Deductions: If you have substantial qualifying expenses, you may benefit from itemizing your deductions. Itemized deductions include:
    • Mortgage interest
    • State and local taxes
    • Charitable contributions
    • Medical expenses

Calculating Exemptions

For 2023, you can claim a personal exemption of $0 for yourself and your spouse. Dependent exemptions have been eliminated.

Determining Business Income

To calculate your taxable income, you must first determine your business income. Here are the steps to follow:

  • Identify your sources of business income: This includes income from sales, services, and any other business activities.
  • Gross income: Calculate the total amount of income received from all sources.
  • Subtract allowable expenses: Expenses related to your business, such as advertising, rent, and equipment costs, can be deducted from your gross income.
  • Cost of goods sold: If you sell products, calculate the cost of goods sold by subtracting the inventory value at the beginning of the year from the inventory value at the end of the year.
  • Net business income: Subtract the cost of goods sold from your gross income. This is your net business income, which is subject to taxation.

Once you have determined your net business income, you can use this figure to calculate your taxable income. This involves subtracting any personal exemptions or deductions from your business income.


Consider the following example:

Gross income$100,000
Less: Allowable expenses$20,000
Net business income$80,000
Less: Exemptions and deductions$10,000
Taxable income$70,000

Accounting for Capital Gains and Losses

When you sell assets, such as stocks or real estate, you may have a capital gain or loss. Capital gains and losses are taxed differently than ordinary income, so it’s important to account for them correctly on your tax return.

Capital Gains

  • Short-term capital gains are taxed at your ordinary income tax rate.
  • Long-term capital gains are taxed at a lower rate than short-term gains, but the rate depends on your income.

Capital Losses

  • Short-term capital losses can offset short-term capital gains.
  • Long-term capital losses can offset long-term capital gains.
  • Any capital losses that exceed your capital gains can be used to offset up to $3,000 of ordinary income. Losses that cannot be used in a current year can be carried forward to future tax years.


The following table shows how capital gains and losses are taxed for different income levels:

IncomeShort-Term Capital Gains Tax RateLong-Term Capital Gains Tax Rate
Under $40,00010%0%
$40,000 to $441,50015%15%
Over $441,50020%20%
