4. Inventory & Cost of Goods Sold (COGS)

Deduct the cost of products you sell:

      • Raw materials, manufacturing costs, storage, and direct labor.


5. Retirement Contributions

      • SEP IRA or Solo 401(k): Contributions are deductible up to IRS limits.

7. Travel Expenses

For business trips away from your tax home:

      • Unpaid invoices from clients (if previously reported as income).

9. Charitable Contributions

      • Donations to qualified nonprofits (cash or goods).

10. Depreciation

      • Spread the cost of long-term assets (e.g., equipment, computers) over their useful life.

11. Startup Costs

      • Deduct up to $5,000 in initial business expenses (e.g., market research, legal fees).


Non-Deductible Expenses

IRS says “NO” to these:

      • Personal expenses (e.g., groceries, vacations).
      • Political contributions or lobbying.
      • Fines or penalties (e.g., traffic tickets).
      • Life insurance premiums (if you’re the beneficiary).
