Sole proprietor tax deductions

Varies

What Can a Sole Proprietor Deduct?

Short answer: Sole proprietors deduct business expenses on Schedule C, plus above-the-line deductions for half of SE tax, health insurance, and SEP or solo 401(k) contributions, and the 20% QBI deduction.

You can't pay yourself a deductible salary; your profit is your taxable income.

Records to keep: Keep receipts, statements, and a simple log of business purpose; compare itemizing to the standard deduction each year.
