How to Save on Taxes When You're Self-Employed

Being self-employed means you're responsible for both the employee and employer portions of Social Security and Medicare taxes — a 15.3% self-employment tax on top of regular income tax. But it also means you have access to deductions and retirement accounts that can dramatically reduce what you owe.

The Self-Employment Tax Deduction

The IRS lets you deduct half of your self-employment tax from your gross income. If you paid $6,000 in self-employment taxes, you can deduct $3,000 from your taxable income. This partially offsets the extra burden of paying both sides.

Business Expense Deductions

Any expense that is 'ordinary and necessary' for your business is deductible. Common examples:

• Home office: deduct the portion of rent/mortgage proportional to your office space
• Phone and internet: the business-use percentage is deductible
• Equipment and software: computers, cameras, subscriptions used for work
• Health insurance premiums: 100% deductible if your spouse can't get employer coverage
• Vehicle mileage: 67 cents per mile driven for business in 2024
• Professional development: courses, books, conferences
• Marketing and advertising: website, ads, business cards
• Professional services: accountant, lawyer, business coaches

Retirement Accounts for the Self-Employed

This is the biggest tax-saving opportunity most self-employed people underuse. Money contributed to these accounts reduces your taxable income dollar-for-dollar:

• SEP-IRA: Contribute up to 25% of net self-employment income, max $69,000 (2024). Simple to open, flexible contributions year to year.
• Solo 401(k): Contribute both as 'employee' ($23,500 limit) and 'employer' (25% of net income). Higher total limit than SEP-IRA for many people. More paperwork.
• SIMPLE IRA: $16,500 limit (2024), good for consistent income. Less flexible than SEP-IRA.

Example: You earn $80,000 net self-employment income. Contributing $20,000 to a SEP-IRA drops your taxable income to $60,000 — saving you thousands in taxes while building retirement wealth.

Health Insurance Deduction

If you're self-employed and pay for your own health insurance (and dental and vision), you can deduct 100% of the premiums from your taxable income — as long as your spouse doesn't have access to employer-sponsored coverage. This includes premiums for yourself, your spouse, and your dependents.

Quarterly Estimated Taxes — Avoid Penalties

Unlike employees, self-employed people don't have taxes withheld automatically. You need to pay quarterly estimated taxes — typically in April, June, September, and January.

If you underpay, the IRS charges a penalty. A simple rule: pay at least 100% of last year's tax bill (or 110% if you earned over $150,000) split into four payments. This creates a 'safe harbor' and avoids penalties even if you owe more at the end of the year.

Qualified Business Income (QBI) Deduction

If you operate as a sole proprietor, partnership, or S-corp, you may be eligible to deduct up to 20% of your qualified business income. This deduction phases out for higher incomes in some service industries. Consult a tax professional to see if you qualify — it can be one of the largest deductions available.
