The One Big Beautiful Bill Act (OBBBA) made 2026 one of the most favorable tax years for small businesses in decades. With the QBI deduction at 23%, Section 179 limits at $2.56 million, and 100% bonus depreciation permanently restored, the incentive to document every deductible expense has never been higher.
This is your complete, category-by-category checklist of small business tax deductions for 2026. Bookmark it, share it with your accountant, and use it throughout the year to make sure you’re not leaving money on the table.
How Tax Deductions Work for Small Businesses
A tax deduction reduces your taxable income, which reduces how much you owe in taxes. For small businesses operating as pass-through entities (sole proprietorships, LLCs, S-Corps, partnerships), deductions are even more powerful in 2026 because they also affect your 23% QBI deduction.
Example: A $1,000 business expense deduction for a small business owner in the 24% bracket saves roughly:
- $240 in federal income tax
- ~$153 in self-employment tax (if sole proprietor)
- The QBI benefit adjusts your overall calculation favorably
- Total savings: ~$393+ from a single $1,000 deduction
The key: you can only deduct what you can document. No receipt = no deduction. That’s why tracking receipts year-round is essential.
