Understanding Portability of the Estate Tax Exemption

Estate planning could seem daunting, but it can also be made simpler by understanding key concepts. One of which focuses on the “portability” of estate tax exemption. Portability is a provision that allows a surviving spouse to add any remaining federal estate tax exemption from the deceased spouse to their own. Here’s how it works.

If you’re preparing an estate plan, a financial advisor can help you understand key concepts to protect your assets.

How Portability in Estate Planning Works

Portability could effectively double the tax exemption that a surviving spouse can use, thereby reducing tax liabilities. It was introduced by the Tax Relief, Unemployment Insurance Reauthorization, and Job Creation Act of 2010 and was made permanent by the American Taxpayer Relief Act of 2012. 

As an example, let’s take a couple where a spouse dies first and leaves behind an exemption of $5 million that was not used. The surviving spouse can now add this $5 million to their own exemption, thereby increasing the tax-free estate value.

This is an effective way to maximize the combined estate tax exemption.

Benefits of Portability for Spouses in Estate Planning 

Portability makes estate planning simpler and maximizes tax benefits. It allows couples to use their full estate tax exemption without having to rely on complicated strategies like credit shelter trusts.

Many tax payers believe incorrectly that portability could diminish the value of their estates. But by utilizing the unused part of the estate tax exemption from a deceased spouse, the surviving spouse could also save on estate taxes and thereby preserve more of the estate for beneficiaries.

You should note, however, that portability also has limitations. Apart from being applicable only to federal estate taxes and not most state-imposed estate taxes, it’s important to understand that portability is not automatic. You must elect for it by the executor of the estate of the deceased spouse within five years of the date of death.

Key Points to Know About Portability

Here are key components that could change how you use the estate tax exemption. There are two main points to consider: 

  • The exempt amount is increased for inflation each year. This means that the total exemption for a married couple can potentially increases each year, providing a bit more tax relief over time.
  • Portability works with the gift tax. The unused exemption inherited by the surviving spouse can be used to make tax-free gifts in their lifetime, sheltering the estate from further taxes.

Utilizing Portability for Strategic Gifting

Strategic gifting is one effective application of portability. The concept is that the surviving spouse can make significant gifts during their lifetime by leveraging the deceased spouse’s unused exemption. This can result in the reduction of the taxable estate. 

To clarify, a surviving spouse with an unused exemption of $5 million becomes able to gift up to this amount during their lifetime without incurring any gift tax. In doing so, this could allow you to transfer additional wealth to your beneficiaries tax-free.

Bottom Line

A financial advisor goes over the tax rules for using portability in a senior couple's estate plan.

Understanding portability, its benefits, and its limitations is an essential component of effective estate planning. It’s a powerful tool that can maximize estate tax exemption benefits, minimize potential estate taxes and enable strategic gifting. It’s also a dynamic process requiring timely actions. Some actionable steps include being proactive in understanding your estate’s value, making decisions about portability early on and tracking inflation-adjusted exemption increases yearly.
