How to use this checklist
Work through each category and enter your estimated annual amount for each deduction that applies to your situation. The tool calculates your total deductions and shows your estimated tax savings in real time.
These deductions reduce your net profit on Schedule C — the number your income tax and self-employment tax are calculated on. Every dollar of deductions saves you roughly 25–40 cents in taxes depending on your bracket.
What counts as a deduction?
The IRS standard: expenses that are ordinary (common in your industry) and necessary (helpful and appropriate for your business). When in doubt, ask: would I have this expense if I didn't have this business?
Keep receipts and records for everything. The IRS can audit up to 3 years back, and documentation is your protection. See our full 1099 deductions guide for detailed explanations of each category.
