How to Prepare (Regardless of Congress)
| Strategy | Who Benefits | Action |
|---|---|---|
| Accelerate income into 2025 | Everyone who can | Bonuses, Roth conversions before rates rise |
| Roth conversions | High earners with traditional IRAs | Convert while rates are lower |
| Defer deductions to 2026 | Itemizers | Bunch charitable giving, medical expenses into 2026 |
| Maximize SALT planning | High-tax state residents | SALT cap may be lifted (benefit of itemizing returns) |
| Estate planning | Net worth >$7M | Gift assets before exemption drops |
| Review withholding | W-2 employees | Adjust W-4 if rates increase |
| Max out QBI deduction | Business owners, freelancers | Maximize pass-through deduction while available |
Bottom Line
Whether TCJA is extended, partially extended, or expires, you should prepare for higher tax rates. The most impactful moves: do Roth conversions while rates are still low, maximize the QBI deduction if you’re self-employed, and review your estate plan if your net worth is above $7 million. Even if Congress extends some provisions, the tax landscape will shift — stay informed and flexible.
