1. Accelerate Expenses You Already Planned
Prepay rent, subscriptions, supplies you were going to buy anyway. Deduct this year if paid by Dec 31. Cash flow neutral — just shifts timing.
2. Use De Minimis Safe Harbor for Small Purchases
Items ≤$2,500 per invoice → expense immediately (no depreciation). Written policy required. Saves time and boosts current-year deductions.
3. Maximize Section 179 & Bonus Depreciation
Section 179: up to $1.22M (2025) immediate expensing on qualifying assets.
Bonus: 60% in 2025. Place equipment in service by Dec 31.
4. Bunch Charitable Contributions
Donate in one year to exceed standard deduction. Use donor-advised fund for multi-year bunching. Cash or appreciated stock.
5. Top Off HSA & Retirement Accounts
HSA: up to $4,300 single / $8,550 family (2025) + $1,000 catch-up if 55+.
Solo 401(k)/SEP: fund by tax deadline (including extensions).
6. Capture R&D Credit Basics
Qualifying wages, supplies, contract research. Even small startups can claim. Document time + project notes. Carryforward if no current tax.
7. Use the Augusta Rule for Home Rentals
Rent home to business for up to 14 days tax-free (Augusta Rule). Business deducts rent. Document fair market rate, agreement, invoice.
8. True-Up Estimated Taxes Before Year-End
Run projection now. Increase withholding or make Q4 estimate payment by Jan 15 to avoid underpayment penalty.
9. Clean Books for QBI Deduction
Accurate books → full 20% QBI deduction. Separate income/expenses, reconcile monthly, document reasonable compensation (S Corp).
10. Prepay Legitimate Business Expenses
Prepay insurance, dues, subscriptions (≤12 months) → deduct this year. Cash flow neutral if planned.
