Business Tax Returns For Real Business Owners
1120 • 1120-S • 1065 • Schedule C — All Filed by a CPA
Most small businesses overpay 5-12% on taxes because their preparer didn't understand the entity choice, depreciation rules, or QBI deduction. We do — and we make it count.

Where We Find Real Tax Savings
These are the deductions and elections small business owners miss.
QBI Deduction — Now 23%
The Qualified Business Income deduction jumped to 23% in 2026. For an S-Corp owner with $150K of QBI, that\'s a $34,500 federal deduction. We calculate phaseouts, SSTB classification, W-2 wage limit, and UBIA tests.
Section 179 + 100% Bonus Depreciation
H.R. 8415 restored 100% bonus depreciation. Combined with Section 179 ($1.16M cap), most business equipment can be fully expensed in year 1. We model both options to maximize current-year deduction.
Accountable Reimbursement Plans
Most S-Corp owners pay business expenses personally. With a written accountable plan, you reimburse yourself tax-free — saving payroll tax. We draft the plan and document the reimbursements.
Augusta Rule (Section 280A)
Rent your home to your S-Corp for legitimate business meetings up to 14 days/year — tax-free income. We document fair market rate and meeting purpose to bullet-proof the deduction.
Retirement Plan Optimization
SEP-IRA, Solo 401(k), Defined Benefit plans for high-income owners. A Solo 401(k) at age 50+ can shelter $76,500/year. We model the best plan for your income and projected growth.
R&D Tax Credit (Restored)
H.R. 8415 restored immediate R&D expensing for small businesses with under $25M in revenue. If you build software, develop products, or innovate processes — we can claim it.
