Tax Guide for Small Business Owners

Filing season doesn't have to be a source of stress. If your small business brings in freelance income, real estate earnings, or capital gains, this simplified US tax guide is for you. 

1. Do You Need to File?

• File if you owe federal income tax or had any withholding.
• Self-employed or freelance income over $400? You must file and pay self-employment contributions.
• Filing can still trigger a refund even if you owe nothing.

2. Filing Tools and Services

• Options: paper, digital tax software (like TurboTax), or hire a CPA.
• IRS Free File helps with simple tax returns.
• More income sources = more complexity (and often more cost).

3. What Counts as a Deduction?

• Standard deduction (2024): $14,600 for singles, $29,200 for married couples.
• Itemize if needed: mortgage interest, state/local taxes, donations.
• Other deductions: IRA contributions, student loan interest, and part of self-employment tax.

4. Understanding Tax Brackets

• Income is taxed progressively, bracket by bracket.
• Only the income within a bracket is taxed at that rate.

5. Get Withholding Right

• Use updated Form W-4.
• Use the IRS estimator if you’ve got multiple income streams.
• Ideally? Owe a little or get a small refund. Keep cash flow smooth.

6. Tax Credits vs. Deductions

• Credits reduce your tax bill dollar for dollar.
• Big ones: Child Tax Credit, Earned Income Credit, Education Credit.
• Some are refundable—meaning you get a refund even if you owe nothing.

7. Other Tax Types to Know

• Self-employment tax: covers Medicare + Social Security (15.3%).
• Capital gains tax: varies by holding period + income (0%, 15%, 20%).
• State/local taxes: may apply depending on where you live.

FAQs

Q: Should I hire a tax professional?
