The 2010 Tax Relief Act temporarily increased the federal estate and gift tax exemption to $5 million per individual, a significant rise from prior years. As the 2012 fiscal cliff approached, concerns grew that these higher exemptions might be reduced, prompting a surge in estate planning activities. During this period, Spousal Lifetime Access Trusts (SLATs) gained popularity as estate planners promoted them as a strategic tool to lock in the increased exemption, allowing one spouse to make substantial gifts to a trust benefiting the other spouse while still retaining some access to the assets.
