Deductions Most Business
Owners Don't Know About
Beyond the obvious deductions — supplies, software, mileage — there's a second tier of legitimate strategies most business owners never use. Each one is worth a few thousand dollars; stacked together they often add up to $20K-$50K+ in additional deductions per year.
The strategies
Augusta Rule (Section 280A)
Rent your personal home to your business for up to 14 days per year. Business deducts the rent. You receive it tax-free. For a board meeting, retreat, or client event, charge fair-market rates ($800-$5K/day depending on home and area). Tax-free income, deductible expense.
Hiring your kids
Pay your children (7+ years old, real work) up to the standard deduction (~$14,600 in 2025) — fully deductible to the business, fully tax-free to the child. Open a Roth IRA in their name. Massive long-term wealth-building loophole.
Accountable plan reimbursements
Set up a written accountable plan so the business reimburses you tax-free for home office, cell phone, internet, mileage, and other mixed-use expenses. Cleaner than deducting them on Schedule C and more powerful with an S-Corp.
Home office deduction (done right)
If you have a dedicated home office, you can deduct utilities, depreciation, mortgage interest %, repairs %, etc. Often $3K-$10K of deduction. Most owners either skip this entirely or use the simplified $5/sqft method (which usually leaves money on the table).
Vehicle deduction (Section 179 / bonus depreciation)
Vehicles over 6,000 lbs GVWR used 50%+ for business can be deducted aggressively — sometimes 60-100% in year 1. Different rules apply to passenger vehicles. Done right, a new SUV can be a $50K+ deduction.
Health Savings Account (HSA)
Triple tax-free: deductible going in, grows tax-free, comes out tax-free for medical. $4,300 single / $8,550 family (2025). For business owners with high-deductible plans, this is one of the best accounts in the entire tax code.
Cost segregation on real estate
If you own commercial or rental real estate, a cost segregation study identifies components (carpets, lighting, paving) that can be depreciated over 5/7/15 years instead of 39. Frontloads $50K-$300K+ of deductions for properties bought in the last few years.
Travel and meals (50%) done right
Business travel with substantive business activity is 100% deductible. Meals with clients/employees are 50%. Document the business purpose. Most owners leave thousands undeducted because they don't track properly.
The documentation rule
Every strategy above is legal. Most get challenged when audited only because the owner didn't document properly. Keep contemporaneous records — receipts, business-purpose notes, written plans, fair-market-rate research. The strategies aren't aggressive. The documentation matters.
