Key Business Tax Terms
Gross Income
Definition: Gross income includes all earnings in the form of money, goods, property, and services that are not tax-exempt. For businesses, it includes total sales minus the cost of goods sold, plus any additional income.
Example: If your business sells products worth $500,000 and the cost of goods sold is $200,000, your gross income is $300,000.
Adjusted Gross Income (AGI)
Definition: AGI is total gross income minus specific deductions. It primarily applies to individuals but is crucial for sole proprietors, influencing tax brackets and deduction eligibility.
Example: If your gross income is $100,000 and you deduct $20,000 for retirement contributions and student loan interest, your AGI is $80,000.
Employer Identification Number (EIN)
Definition: A unique nine-digit number assigned by the IRS to identify a business for tax filing and reporting purposes.
Example: A corporation applies for an EIN to report its taxes and hire employees, functioning similarly to a Social Security number for businesses.
Self-Employment Tax
Definition: A tax consisting of Social Security and Medicare taxes for self-employed individuals, similar to payroll taxes for employees.
Example: If you earn $50,000 in net self-employment income, you must pay self-employment taxes at approximately 15.3% (as of 2025).
Estimated Taxes
Definition: Quarterly advance tax payments for income not subject to withholding, such as self-employment earnings, interest, or rental income.
Example: A freelance graphic designer expecting to owe $10,000 in taxes must make four quarterly payments of $2,500.
Additional Tax Concepts
- Tax Deductions: Eligible expenses reducing taxable income, such as office supplies, rent, and salaries.
- Depreciation: Allocating the cost of a business asset over its useful life to recover costs through tax deductions.
- Tax Credits: Direct reductions in tax owed, such as the R&D credit or Small Business Health Care Tax Credit.
- Pass-Through Taxation: Business profits and losses pass through to the owner’s personal tax return instead of corporate taxation.
- Withholding Tax: Taxes deducted from employee wages and sent to the IRS, covering income and payroll taxes.
- Tax Liability: The total tax amount a business or individual owes after deductions and credits.
- Fiscal Year vs. Calendar Year: A fiscal year is any 12-month period a business selects for tax reporting, while a calendar year runs from January 1 to December 31.
- IRS Form 1099: Used to report non-employee income over $600, such as freelance earnings.
- Payroll Taxes: Taxes employers withhold from wages and contribute on behalf of employees.
- Business Tax Extensions: Extensions allow more time to file returns but do not extend tax payment deadlines.
