A small business deduction list is a catalog of qualified business expenses that reduce taxable income under IRS tax code Section 199A. These deductions apply to sole proprietorships, partnerships, and S corporations.
The IRS allows small businesses to deduct ordinary and necessary expenses from gross income. Ordinary expenses are common in your industry, while necessary expenses are helpful and appropriate. For example, a graphic designer can deduct software subscriptions like Adobe Creative Cloud.
Deductions lower taxable income, reducing the amount owed to the IRS. The Section 199A deduction lets eligible businesses deduct up to 20% of qualified business income. This applies to pass-through entities like sole proprietorships and LLCs.
| Deduction Type | Examples | IRS Code Section |
|---|---|---|
| Home Office | Rent, utilities, internet, mortgage interest | 280A |
| Equipment Purchases | Computers, printers, software | 179 |
| Vehicle Expenses | Gas, maintenance, insurance | 280F |
| Travel and Meals | Airfare, hotels, 50% of meals | 274 |
| Health Insurance | Premiums for self, spouse, dependents | 162(l) |
Note that the IRS requires detailed records for all deductions. Keep receipts, invoices, and mileage logs for at least three years.
Many small business owners confuse personal expenses with business deductions. The IRS scrutinizes deductions for excessive personal use, such as claiming a vacation as a business trip. Another mistake is missing deadlines for depreciation or amortization schedules.
For example, a freelance writer claimed a $3,000 deduction for a new laptop but forgot to include the receipt. The IRS disallowed the deduction during an audit because there was no proof of purchase.
The Section 199A deduction allows qualified businesses to deduct 20% of qualified business income. This deduction phases out for service businesses earning over $164,900 (single filers) or $329,800 (married filing jointly).
To claim this deduction, ensure your business meets the IRS criteria for qualified trades or businesses. Consult a tax professional if unsure about eligibility.
When I ran a small marketing consultancy, I claimed deductions for software subscriptions, coworking space rent, and business travel. Keeping detailed records helped me avoid issues during tax season. I used accounting software to track expenses and generate reports for my CPA.
One year, I accidentally mixed personal and business expenses. My accountant caught the error and adjusted my deductions before filing. This saved me from potential penalties and ensured accuracy.
