SLAT: The “Have Your Cake and Eat It Too” Strategy

By Team BMT Feb 01, 2026

💡 Executive Summary

  • Problem: You want to use your $13.6M Lifetime Exemption before it gets cut in 2026, but you are afraid to give the money away because you might need it later.
  • Solution: Create a Spousal Lifetime Access Trust (SLAT). You gift assets to a trust for the benefit of your Spouse (and kids).
  • Result: The assets are out of your estate (no Estate Tax), but your spouse can request distributions. Since you are married, you indirectly regain access to the funds.
⚠️ THE “DIVORCE & DEATH” RISK
If your spouse dies or you get divorced, your access to the trust is cut off immediately.
Solution 1 (Divorce): Use a “Floating Spouse” clause (Trust benefits “whoever I am currently married to”).
Solution 2 (Death): Buy Life Insurance on your spouse to replace the lost liquidity.

The SLAT is the most popular strategy for the “Not-Quite-Billionaire” (Tier L2/L3). It solves the psychological barrier of “Irrevocable Trusts.” Technically, the gift is irrevocable. Practically, as long as your marriage is solid, the money is still in the family checkbook.

🧐 Core Mechanic: Reciprocal Trust Doctrine
Husband creates a SLAT for Wife. Wife creates a SLAT for Husband. (Double Win?)
WARNING: If the trusts are identical, the IRS un-does them (Reciprocal Trust Doctrine). To work, the trusts must be substantially different (e.g., different trustees, different terms, different assets, created at different times).

The SLAT is the estate planning equivalent of a boomerang. You throw the assets away to avoid taxes, but they curve back to your household through your spouse.”
