What actually reduces estate tax, and what does not

Estate tax only applies to estates larger than a threshold set by federal law. That threshold changes every few years and varies by state. The single most effective way to reduce estate tax is to own less when you die — which sounds obvious but shapes every real strategy that works.

You cannot avoid estate tax by hiding money, moving it offshore, or putting it in someone else's name without proper documentation. The IRS values your estate based on what you owned at death, regardless of where it sits. What you can do is transfer money during your lifetime in ways the tax code permits, structure your assets so they pass outside your taxable estate, or use trusts that are designed specifically to reduce what the IRS counts.

The strategies that actually work fall into three categories: giving money away now, using trusts to hold assets outside your estate, and structuring how you own property with other people. Each has rules about how much you can do and when, and each costs money to set up correctly.

Key Takeaways

  • The federal estate tax threshold is high enough that most estates do not owe it, but state estate taxes have lower thresholds in some states and explore to smaller estates.
  • Giving money to family members during your lifetime removes it from your taxable estate permanently, and you can give up to a set amount per person per year without filing paperwork.
  • Irrevocable trusts, life insurance trusts, and charitable trusts can hold assets outside your estate, but once you fund them you cannot take the money back.
  • Owning property as "tenants by the entirety" or in a limited liability company can reduce what passes through your estate, but the rules depend on your state and the type of property.
  • A will alone does not reduce estate tax — it only determines who receives assets after taxes are paid.

Giving money away during your lifetime

The federal tax code allows you to give money to other people without triggering a gift tax, up to a yearly limit per recipient. That limit changes annually. In 2024, you can give up to $18,000 per person per year without filing a gift tax return. A married couple can give $36,000 per person per year if both spouses agree. Money given this way leaves your taxable estate when ready and permanently.

Beyond the yearly limit, you have a lifetime exemption — a total amount you can give away or leave at death before federal estate tax applies. That exemption is also high and changes every few years. It is currently over $13 million per person, but it is scheduled to drop significantly after 2025 unless Congress extends it. Gifts that exceed the yearly limit count against your lifetime exemption, but they do not trigger a tax bill during your life.

The key to using this strategy is timing and documentation. Gifts must be genuine — the money or property must actually transfer, and you must not retain control over it. A check to your child that they deposit in their own account counts. A transfer to an account you still control does not. If you want to give large amounts, work with a tax professional to document the gifts correctly and file the required forms.

Irrevocable trusts and life insurance trusts

An irrevocable trust is a legal structure you fund with money or property, and once funded, you cannot take it back or change the terms. The assets inside the trust are no longer part of your taxable estate — they belong to the trust. When you die, those assets pass to your beneficiaries without going through your estate and without owing federal estate tax on them.

The trade-off is control. Once you put money in an irrevocable trust, you cannot access it, change who receives it, or modify the trust terms. This makes irrevocable trusts useful for people who are certain about their wishes and want to remove assets from their estate now. They are often used to hold property for grandchildren or to fund long-term care for a family member.

An irrevocable life insurance trust (ILIT) is a specific type designed to hold a life insurance policy. When you die, the insurance payout goes to the trust instead of your estate. This keeps the payout out of your taxable estate, which can save substantial tax if the policy is large. Setting up an ILIT requires naming the trust as the policy owner and beneficiary, and this must be done correctly or the strategy fails. Most people need an attorney to set this up.

Charitable trusts and donations

If you plan to leave money to charity, a charitable remainder trust or charitable lead trust can reduce your taxable estate while providing income to you or your family during your lifetime. These trusts are irrevocable and require professional setup, but they offer tax benefits that make sense for large charitable gifts.

A simpler approach is to donate appreciated assets — stocks, real estate, or art that has increased in value — directly to a charity. You receive a tax deduction for the fair market value, and the asset leaves your estate. This works particularly well if you own stock that has grown significantly, because you avoid capital gains tax on the appreciation and reduce your estate at the same time.

Charitable strategies only reduce estate tax if you actually intend to give money to charity. The IRS will not allow you to claim a charitable deduction for assets you plan to leave to family members, even if you structure them as a trust.

Ownership structures that affect estate tax

How you own property matters for estate tax. If you own real estate or investments as tenants by the entirety with a spouse, only half the value is included in your taxable estate when you die. The other half passes to your spouse automatically and is not taxed at that time. This structure is available in some states for married couples only, and it does not work for unmarried partners.

A limited liability company (LLC) or family limited partnership (FLP) can reduce the value of your estate for tax purposes. You transfer assets into the entity and retain a controlling interest, while giving non-controlling interests to family members. The non-controlling interests are worth less than their proportional share of the assets — sometimes significantly less — because they do not include management rights. The IRS allows this discount, which reduces your taxable estate. However, the IRS scrutinizes these structures carefully, and they must be set up and maintained correctly to hold up in an audit.

These ownership structures require legal setup and ongoing maintenance. They also have annual costs for filing and accounting. They make sense only if your estate is large enough that the tax savings exceed the cost of maintaining the structure.

Portability and spousal planning

If you are married, your spouse can use your unused lifetime exemption when you die — a concept called portability. This means if you die with a small estate and do not use your full exemption, your spouse can use the unused portion in addition to their own exemption. This effectively doubles the exemption for married couples without requiring any trust or complex structure.

Portability is automatic in some cases but requires filing a specific tax return (Form 706) within nine months of death to preserve it. If your estate is small enough that you would not normally file a return, you may still need to file one just to preserve portability for your spouse. A tax professional can tell you whether this makes sense in your situation.

For couples with very large estates, more complex spousal planning may make sense — such as a credit shelter trust that uses one spouse's exemption while preserving the other spouse's exemption for later. These strategies require professional design and should be reviewed every few years as tax law changes.

State estate and inheritance taxes

Twelve states plus Washington D.C. have their own estate taxes, and six states have inheritance taxes. The thresholds are much lower than the federal threshold — some state estate taxes explore to estates over $1 million or less. If you live in or own property in a state with an estate tax, you may owe state tax even if your estate is too small for federal tax.

State tax strategies are different from federal strategies and depend on which state you live in and where your property is located. Real estate is taxed by the state where it sits. Bank accounts and investments are taxed by your state of residence. If you own property in multiple states, you may need to plan for multiple state taxes. A tax professional in your state can tell you what applies to your situation.

Frequently Asked Questions

Do I need to do anything about estate tax if my estate is small?

Most estates do not owe federal estate tax because the threshold is high. However, if you live in a state with an estate tax, the threshold may be lower. Check your state's rules or speak with a tax professional. If you have no state estate tax and your estate is below the federal threshold, you do not need estate tax planning — a will is sufficient.

Can I reduce estate tax by putting property in my child's name?

Putting property in someone else's name without proper documentation does not reduce estate tax — the IRS will still count it as yours. If you genuinely transfer ownership and give up all control, it may reduce your estate, but this creates other problems: your child could lose it to creditors, it may trigger gift tax reporting, and you lose control of the asset. Consult a tax professional before transferring property.

What happens to my estate tax plan if the law changes?

The federal exemption amount changes every few years and is scheduled to drop significantly after 2025. If you have an irrevocable trust or other estate plan, you should review it every few years with a tax professional to make sure it still makes sense under current law. Some strategies that work now may not work as well after the law changes.

Is a revocable living trust better than a will for avoiding estate tax?

A revocable living trust does not reduce estate tax — assets in a revocable trust are still part of your taxable estate. A revocable trust is useful for avoiding probate and keeping your affairs private, but it does not save tax. If you want to reduce estate tax, you need an irrevocable trust or one of the other strategies described here.

Should I hire an attorney or a tax professional to set up an estate plan?

If your estate is small and you have no state estate tax, you may not need professional help. If your estate is large, you own property in multiple states, or you want to use trusts or other tax strategies, you should work with both an attorney (to draft the documents) and a tax professional (to plan the tax strategy). These professionals work together and the cost is usually worth the tax savings.
