Gift Tax Calculator

The federal gift tax is a tax imposed by the IRS on the transfer of money or property from one person to another when the giver receives nothing, or less than full value, in return. It is the donor — the person giving the gift — not the recipient, who is responsible for paying gift tax if any is owed. Understanding how the gift tax works is essential for anyone planning to transfer significant wealth to family members, friends, or others during their lifetime.

Gift tax applies to a wide range of transfers including cash gifts, real estate, stocks and securities, business interests, and forgiven loans. The IRS uses the gift tax system in conjunction with the estate tax to prevent wealthy individuals from avoiding estate tax simply by giving away assets before death. Together, they form a unified transfer tax system with a single lifetime exemption that spans both your lifetime gifts and your estate.

For 2024, the IRS sets the annual gift tax exclusion at $18,000 per recipient. This means you can give up to $18,000 to as many individuals as you like in a calendar year without triggering any gift tax or even a filing requirement. Gifts above this threshold per recipient must be reported to the IRS, though they typically do not result in immediate tax because of the generous lifetime exemption.

The lifetime gift and estate tax exemption for 2024 is $13,610,000 per individual. This means most Americans will never owe federal gift tax — only donors who give cumulative taxable gifts exceeding $13.61 million over their lifetimes will actually owe tax. The maximum gift tax rate on amounts exceeding the lifetime exemption is 40%.

This gift tax calculator uses the actual 2024 IRS figures — $18,000 annual exclusion, $13,610,000 lifetime exemption, and 40% maximum rate — to give you an accurate estimate of your federal gift tax liability and remaining exemption capacity.

This calculator follows the exact IRS methodology for computing federal gift tax. Enter your total gift amount, the number of recipients, your filing status, and how much of your lifetime exemption you have already used. The calculator instantly shows your taxable gift, how much lifetime exemption is applied, and the resulting tax owed — if any.

The core calculation works in three steps. First, the gift is divided equally among all recipients. Second, the annual exclusion is subtracted from each recipient's share. Third, any remaining taxable amount is offset against your remaining lifetime exemption before applying the 40% tax rate to any residual balance.

Special situations are also handled: married couples who elect gift splitting effectively double the annual exclusion to $36,000 per recipient. Gifts made directly to a spouse qualify for the unlimited marital deduction, resulting in zero gift tax regardless of amount. Qualified education and medical expenses paid directly to the institution or provider are also fully excluded, though these are tracked separately from the standard annual exclusion.

The annual gift tax exclusion is one of the most powerful and underutilized tax planning tools available. In 2024, every individual can give up to $18,000 per recipient per year with no gift tax consequences and no requirement to file Form 709. This exclusion is per-recipient, not per-donor in total, meaning a parent with three children can give each child $18,000 — a combined $54,000 — in a single year without any tax or filing obligation.

The annual exclusion is indexed for inflation in $1,000 increments, so it has risen over time from $10,000 in earlier years to the current $18,000 for 2024. Staying within the annual exclusion is the simplest way to transfer wealth gift-tax-free over time. A couple who consistently gives each of their three children the annual exclusion can transfer over $100,000 per year with no tax cost.

Gift splitting is an election available to married couples that effectively doubles the annual exclusion. When both spouses consent to split a gift, a gift made by one spouse is treated as made half by each spouse. This means a married couple can give up to $36,000 per recipient per year without gift tax consequences, even if only one spouse actually writes the check. Gift splitting requires filing Form 709 even if no tax is owed, and both spouses must consent to split all gifts made during the year — you cannot selectively split only some gifts.

To use gift splitting in this calculator, select Yes (Gift Splitting) for the "Married Filing Jointly?" option. The annual exclusion per recipient will automatically double to $36,000, reflecting the combined exclusions of both spouses.

Beyond the annual exclusion, the federal tax code provides a massive lifetime exemption that shields most Americans from ever paying gift tax. For 2024, the unified lifetime gift and estate tax exemption is $13,610,000 per individual. This exemption is "unified" because it applies to the combined total of taxable gifts made during your lifetime and the value of your taxable estate at death.

Every dollar of taxable gift (amounts above the annual exclusion) you make during your lifetime reduces your available exemption dollar-for-dollar. If you give a taxable gift of $500,000, your remaining lifetime exemption drops to $13,110,000. That same $500,000 also reduces your estate tax exemption at death, meaning the unified system prevents double-dipping.

The current historically high exemption amount is scheduled to sunset after 2025 under current law, potentially reverting to approximately $7 million (inflation-adjusted from the pre-2017 $5 million base). This sunset has made lifetime gifting strategies especially attractive for high-net-worth individuals who want to lock in transfers at the higher exemption amount before any potential reduction. Congress could extend or modify this provision, so consulting a tax advisor for current guidance is always recommended.

In this calculator, enter the cumulative amount of taxable gifts you have already reported to the IRS in prior years in the "Lifetime Exemption Already Used" field. The calculator will deduct that amount from the $13,610,000 total to determine your remaining exemption and whether any actual tax is owed on the current gift.

In addition to the annual per-recipient exclusion and the lifetime exemption, the gift tax rules provide three powerful special exclusions that can significantly reduce or eliminate gift tax liability.

Unlimited marital deduction: Gifts between spouses who are U.S. citizens are completely exempt from gift tax, with no dollar limit. If your spouse is not a U.S. citizen, a separate annual exclusion of $185,000 (2024) applies instead of the unlimited deduction. In this calculator, selecting "Gift to Spouse: Yes" applies the unlimited marital deduction and sets the taxable gift and gift tax to zero.

Qualified education exclusion: Tuition payments made directly to a qualifying educational institution — college, university, vocational school — on behalf of any individual are entirely excluded from gift tax, with no dollar limit. The payment must go directly to the school; money given to the student that they then use to pay tuition does not qualify. Room and board, books, and supplies do not qualify for this exclusion. Enter education expenses paid directly to the institution in the "Education Expenses" field to track this exclusion.

Qualified medical exclusion: Payments made directly to a medical care provider for another person's medical expenses are excluded from gift tax without limit. Like the education exclusion, the payment must go directly to the provider — reimbursements to the recipient for expenses they already paid do not qualify. Enter amounts paid directly to medical providers in the "Medical Expenses" field.

These three special exclusions are in addition to and independent from both the annual exclusion and the lifetime exemption. Using them strategically — particularly the qualified education and medical exclusions — can dramatically accelerate tax-free wealth transfer for families with significant educational or medical expenses to cover.

Even if no gift tax is owed, you may be required to file IRS Form 709, the United States Gift (and Generation-Skipping Transfer) Tax Return. Understanding when Form 709 is required helps you stay compliant and avoid IRS scrutiny.

You must file Form 709 if you gave gifts to any single recipient that exceeded the $18,000 annual exclusion in 2024, even if the lifetime exemption entirely covers the taxable amount and no tax is actually owed. You must also file if you and your spouse are electing gift splitting, regardless of the amount. Gifts to non-citizen spouses above $185,000, and gifts of a future interest (such as gifts in trust where the recipient cannot immediately use the gift), always require Form 709.

Form 709 is due on the same date as your individual income tax return — April 15 of the year following the gift — with an automatic extension to October 15 if you file for one. Importantly, filing an extension for your income tax return does not automatically extend the time to file Form 709; you must file a separate extension request using Form 8892 if needed.

Failing to file Form 709 when required can result in IRS penalties, and unreported gifts discovered by the IRS during an estate tax audit can reduce your estate's available exemption and result in unexpected tax liability for your heirs. The calculator flags when a gift tax return is required based on whether your taxable gift exceeds zero.
