Inheriting $300,000 generally does not trigger immediate capital gains tax, as inherited cash is not taxable income. If you inherit assets (property/stocks) worth $300,000, you receive a "stepped-up basis" to the fair market value at the time of death, meaning you only pay taxes on appreciation after you inherit it.
Typically, when you inherit an asset, capital gains tax will not apply. However, when you sell an asset that you have inherited, CGT may become relevant to any money you make from the sale of the asset.
A Beneficiary will not usually be liable to pay Capital Gains Tax on their inheritance. However, if an asset is transferred to them from the Estate (such as shares or a property, for example) and they then sell this at a later date for a profit, they may become liable for Capital Gains Tax at this stage.
Capital gains tax
Capital gains taxes apply to inheritances when the beneficiary decides to sell any of the assets they've inherited. For example, if a grandparent passes away and leaves you $100,000 worth of stock and you later sell it for $150,000, you'll be subject to capital gains tax on the $50,000 gain.
While state laws differ for inheritance taxes, an inheritance must exceed a certain threshold to be considered taxable. For federal estate taxes as of 2024, if the total estate is under $13.61 million for an individual or $27.22 million for a married couple, there's no need to worry about estate taxes.
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pay income tax on inheritances (except for pre-tax retirement funds like IRAs/401(k)s, which are taxed as income when withdrawn), some states have their own estate or inheritance taxes with much lower thresholds, affecting a smaller portion of wealth.
Leave property to your spouse.
This is called the “spousal rollover.” This strategy is extremely useful for property with a large capital gain (e.g., cottage, investment property, land, non-registered investment). If you don't leave your property to your spouse, the capital gains tax will be due when you die.
That means that your net pay will be £172,589 per year, or £14,382 per month. Your average tax rate is 42.5% and your marginal tax rate is 48.3%. This marginal tax rate means that your immediate additional income will be taxed at this rate.
Long-term capital gains tax applies to assets held for more than a year. The long-term capital gains tax rates are 0%, 15% and 20%, depending on your income. For many taxpayers, these rates are much lower than the ordinary income tax rate.
Selling an inherited property as soon as you can is another way to avoid the capital gains tax. When you inherit property, its cost, known in tax jargon as basis, is “stepped up,” or increased from its original cost to its fair market value at the date of the former owner's death.
Your beneficiaries (the people who inherit your estate) do not normally pay tax on things they inherit. They may have related taxes to pay, for example if they get rental income from a house left to them in a will.
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.
You can typically inherit a very large amount from your parents before hitting federal estate tax thresholds, which are around $15 million per individual in 2026, meaning most heirs receive tax-free inheritances because estates rarely exceed this limit; however, some states have their own estate or inheritance taxes, and income from inherited assets (like IRAs or rental income) is usually taxable, according to this U.S. Bank article, this Fidelity article, this Domain Money article, and this Tax Foundation article.
Don't Make Rash Decisions
Paying off high-interest debt can potentially be a good decision for a portion of the inheritance, for example. You may also want to spend part of your $500K inheritance on something fun, or otherwise enjoyable. In the right context and with proper planning, that's not necessarily a bad idea.
What else is a good idea to do with your inheritance? Paying off debt. Like many of us, you may have credit card debt, student loans, a line of credit, or a car loan. You want to start with the highest interest rate debt that you have and pay that off first, and then work your way down.
The "7-year inheritance rule" (primarily a UK concept) means gifts you give away become exempt from Inheritance Tax (IHT) if you live for seven years or more after making the gift; if you die within that time, the gift may be taxed, often with a reduced rate (taper relief) applied if you die between years 3 and 7, but at the full 40% if you die within 3 years, helping people reduce their estate's taxable value by giving assets away earlier.
Yes, you can give your son $100,000 tax-free in 2025 by utilizing the annual gift tax exclusion and your lifetime exemption, but you'll need to report the gift to the IRS on Form 709 since it exceeds the $19,000 annual limit, though you won't pay tax unless you exceed your much larger $13.99 million lifetime gift/estate tax exemption. The gift is considered yours (the giver) for tax purposes, not your son's.
Every individual has a basic Inheritance Tax (IHT) threshold of £325,000, known as the Nil Rate Band. Assets below this value generally pass to beneficiaries free of tax. If the estate is worth more than that, IHT at 40% usually applies on the excess, unless exemptions or reliefs reduce the amount due.
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.
