What Is Tax and Estate Planning for Business Owners?
Tax and estate planning for business owners means lowering today’s tax bill AND ensuring your business, wealth, and legacy pass to the right people smoothly and at the lowest tax cost after you’re gone or retire. This requires integrating annual tax strategy, entity structure, gifting, buy-sell agreements, and estate documents.
Pro Tip: Start your plan at least five years before a planned exit. Trusts, gifting, and restructuring take time to have full effect.
How Does the OBBBA Change Business Tax Planning in 2026?
Quick Answer: OBBBA permanently restored 100% bonus depreciation, raised Section 179 expensing, and increased the federal estate exemption—creating big opportunities for owners who act now.
| Provision | 2026 Rule | Benefit |
|---|---|---|
| Bonus Depreciation | 100% (Permanent) | First-year write-off on facts/equipment |
| Section 179 Limit | $2.5M | Big up-front deduction |
| Estate Exemption | $30M (married) | Minimize transfer tax for most owners |
What Are the Top Tax Deductions for Business Owners?
- Section 179 expensing and 100% bonus depreciation
- Home office & vehicle deductions
- Retirement plan (SEP/Solo 401(k)) contributions
- Self-employed health insurance deductions
- QBI deduction (20% for pass-throughs under Section 199A)
How Does Estate Planning Protect Your Business?
Estate planning ensures your business transfers to heirs or partners with minimal expense, delays, or taxes. With the $30M federal exemption (married) through 2028, now is the best time ever to hand off wealth tax-free.
- Buy-sell agreements for partner businesses
- Irrevocable Life Insurance Trusts (ILITs) for liquidity
- Family Limited Partnerships (FLPs) for family succession/gifting at discounted value
PA Only: PA inheritance tax (up to 15%) applies on business property. Careful planning mitigates state-level taxes, too.
