Inheritance tax (or estate tax) generally must be paid within six to nine months of the date of the decedent's death to avoid interest and penalties. While federal estate tax returns are due in nine months with potential extensions, specific state inheritance taxes (e.g., Kentucky) often require payment within nine months for a 5% discount.
In most cases, when IHT is payable depends on the type of assets within the estate and how they are being transferred. Generally, the tax must be settled within six months from the end of the month in which the individual passed away (HMRC guidance).
In 2025, the first $13,990,000 of an estate is exempt from federal estate taxes, up from $13,610,000 in 2024. Estate taxes are based on the size of the estate. It's a progressive tax, just like the federal income tax system. This means that the larger the estate, the higher the tax rate it is subject to.
You can typically inherit a very large amount from your parents without paying federal tax, as the federal estate tax exemption is around $15 million per person for 2026, meaning only estates larger than that pay tax, not you directly. While you generally don't pay income tax on inheritances (except for pre-tax retirement funds like IRAs/401(k)s, which are taxed as income when withdrawn), some states have their own estate or inheritance taxes with much lower thresholds, affecting a smaller portion of wealth.
Charity exemption
Like the spousal exemption, assets passing to charity on death are exempt from inheritance tax. As such, if an entire estate passes to charity, there will be no inheritance tax due.
If the estate earned income (such as dividends or rental income) after the person's death, a trust is created, and the trustee of the trust (usually the legal personal representative) is required to pay any tax on the net income of the deceased estate.
Children generally inherit significant amounts tax-free due to the high federal estate tax exemption, which is $13.99 million per individual for 2025, with a planned reversion to a lower amount ($5 million adjusted for inflation) in 2026, meaning very large estates are taxed, but most inheritances fall below this threshold, though some states have their own inheritance taxes. Heirs also benefit from the "step-up in basis," which lowers capital gains tax on inherited assets like stocks and real estate.
Yes, you can likely give your daughter $50,000 tax-free by using your annual gift exclusion and lifetime exemption, but you'll need to file Form 709 with the IRS to report the gift exceeding the annual limit ($19,000 in 2024/2025). The $50,000 gift reduces your large lifetime exemption (over $13 million in 2024/2025), meaning you won't pay tax on it unless your total lifetime gifts exceed that huge amount; your daughter never pays gift tax on the money.
The 7 year rule
No tax is due on any gifts you give if you live for 7 years after giving them - unless the gift is part of a trust. This is known as the 7 year rule.
This means that if you inherit a property any time between 1st September and 31st August, you must pay Inheritance or Capital Acquisitions Tax by the 31st October. For example, if you inherited a property on 3rd September 2023, you would have had to pay CAT by 31st October 2024.
The federal estate tax return, Form 706, is due nine months from the decedent's date of death and can be extended an additional six months.
if you dispose of the inherited property within 2 years (or the within an extension period) of the deceased person's death. Note: The 2-year limit is extended if disposal of the property is delayed by exceptional circumstances outside your control.

Give more money away
Lifetime gifting is a straightforward way to begin reducing your IHT bill. By gifting money during lifetime, that would have been part of an inheritance anyway, you reduce the size of your estate so that there is smaller amount subject to IHT on your death.
Ideas for what to do with your inheritance
Inheriting $100,000 or more is often considered sizable. This sum of money is significant, and it's essential to manage it wisely to meet your financial goals. A wealth manager or financial advisor can help you navigate how to approach this.
Yes, you can gift your son $100,000, but since it's over the 2025 annual exclusion of $19,000, you'll need to file a gift tax return (Form 709), though you likely won't owe taxes unless you've already used up your large lifetime exemption (over $13.99 million in 2025). Your son pays no tax on the gift, but you, as the giver, must report the amount exceeding the annual limit, which counts against your lifetime exemption.
