You will need to consider the disposition of your assets at your death and any tax implications. Statistically speaking, women live longer than men. Wives will likely have the last word about the final disposition of all the assets accumulated during marriage. You'll want to consider whether these concepts and strategies apply to your specific circumstances.
Transfer Taxes
When you transfer your property during your lifetime or at your death, your transfers may be subject to federal gift tax, federal estate tax, and federal generation-skipping transfer (GST) tax. (The top estate and gift tax rate is 40%, and the GST tax rate is 40%.) Your transfers may also be subject to state taxes.
Federal Gift Tax
Gifts you make during your lifetime may be subject to federal gift tax. Not all gifts are subject to the tax, however. You can make annual tax-free gifts of up to $17,000 (in 2023) per recipient. Married couples can effectively make annual tax-free gifts of up to $34,000 (in 2023) per recipient. You can also make tax-free gifts for qualifying expenses paid directly to educational or medical services providers. And you can also make deductible transfers to your spouse and charity. Individuals can transfer $12,920,000 free of estate, gift, and GST tax during their lives or at death in 2023.
Federal Estate Tax
Property you own at death is subject to federal estate tax. As with the gift tax, you can make deductible transfers to your spouse and charity. Again, up to $12,920,000 (in 2023) is protected from taxation.
Portability
The estate of someone who dies in 2011 or later can elect to transfer any unused applicable exclusion amount to their surviving spouse; this is called "portability". The surviving spouse can use this deceased spousal unused exclusion amount (DSUEA) and their own basic exclusion amount for federal gift and estate tax purposes. For example, if someone died in 2011 and the estate elected to transfer $5,000,000 of the unused exclusion to the surviving spouse, the surviving spouse effectively has an applicable exclusion amount of about $17,920,000 ($12,920,000 basic exclusion amount plus $5,000,000 DSUEA) to shelter transfers from federal gift or estate tax in 2023.
Federal Generation-Skipping Transfer (GST) Tax
The federal GST tax generally applies if you transfer property to someone two or more generations younger than you (for example, a grandchild). The GST tax may apply in addition to any gift or estate tax. Similar to the gift tax provisions above, annual exclusions and exclusions for qualifying educational and medical expenses are available for GST tax. You can protect up to $12,920,000 (in 2023) with the GST tax exemption.
Indexing for Inflation
The annual gift tax exclusion, the gift tax and estate tax basic exclusion amount, and the GST tax exemption are all indexed for inflation and may increase in future years.
Income Tax Basis
Generally, if you give property during your life, your basis (generally, what you paid for the property, with certain up or down adjustments) in the property for federal income tax purposes is carried over to the person who receives the gift. So, if you give your $1 million home (purchased for $50,000) to your brother, your $50,000 basis carries over to your brother — if he sells the house immediately, income tax will be due on the resulting gain.
In contrast, if you leave property to your heirs at death, they get a "stepped-up" (or "stepped-down") basis in the property equal to the property's fair market value at the time of your death. So, if the home you purchased for $50,000 is worth $1 million when you die, your heirs get the property with a basis of $1 million. If they sell the home for $1 million, they pay no federal income tax.
Lifetime Giving
Making gifts is a common estate planning strategy that can minimize transfer taxes. One way to do this is to take advantage of the annual gift tax exclusion, which lets you give up to $17,000 (in 2023) to as many individuals as you want, gift tax-free. As noted above, you can take advantage of several gift tax exclusions and deductions. In addition, when you gift property expected to appreciate, you remove the future appreciation from your taxable estate. In some cases, it may be beneficial to make taxable gifts to remove the gift tax from your taxable estate.
Trusts
There are a number of trusts used in estate planning. Here is a quick look at a few of them.
Revocable trust: You retain the right to change or revoke a revocable trust. A revocable trust can allow you to try out a trust, provide for management of your property in case of your incapacity, and avoid probate at your death.
Marital trusts: A marital trust is designed to qualify for the marital deduction. Typically, one spouse gives the other spouse an income interest for life, the right to access principal in certain circumstances, and the right to designate who receives the trust property at their death. In a QTIP variation, the spouse who created the trust can retain the right to control who ultimately receives the trust property when the other spouse dies. A marital trust is included in the spouse's gross estate with the income interest for life.
Credit shelter bypass trust: The first spouse to die creates a trust sheltered by their applicable exclusion amount. The surviving spouse may be given interests in the trust, but the interests are limited enough that the trust is not included in their gross estate.
Grantor retained annuity trust (GRAT): You have rights to a fixed stream of annuity payments for a number of years, after which the remainder passes to your beneficiaries, such as your children. Your gift of a remainder interest is discounted for gift tax purposes.
Charitable remainder unitrust (CRUT): You retain a stream of payments for a number of years (or for life), after which the remainder passes to charity. You receive a current charitable deduction for the gift of the remainder interest.
Charitable lead annuity trust (CLAT): A fixed stream of annuity payments benefits a charity for a number of years, after which the remainder passes to your noncharitable beneficiaries, such as your children. Your gift of a remainder interest is discounted for gift tax purposes.
Life Insurance
Life insurance plays a part in many estate plans. Life insurance may create the estate in a small estate and be the primary financial resource for your surviving family members. Life insurance can also provide liquidity for your estate, for example, by providing the cash to pay final expenses, outstanding debts, and taxes, so that other assets don't have to be liquidated to pay these expenses. Life insurance proceeds can generally be received income tax-free.
Life insurance you own on yourself will generally be included in your gross estate for federal estate tax purposes. However, it is possible to use an irrevocable life insurance trust (ILIT) to keep the life insurance proceeds out of your gross estate.
With an ILIT, you create an irrevocable trust that buys and owns the life insurance policy. You make cash gifts to the trust, which the trust uses to pay the policy premiums. (The trust beneficiaries are offered a limited period to withdraw the cash gifts.) If structured properly, the trust receives the life insurance proceeds when you die, is tax-free, and distributes the funds according to the terms of the trust.
As you can see, this area can get very complicated very quickly, and in many cases, the various approaches have pros and cons. If you are considering employing one of these strategies or want more information on how they work, I encourage you to contact a qualified estate planning attorney for further guidance.
