But ignoring it or assuming “it'll all work out” can lead to your family scrambling—and paying the tax man a lot more than necessary. You know what the biggest problem is? using an inheritance tax calculator There’s a strict inheritance tax payment deadline you must meet, or the tax bill gets bigger, and your family may not keep the home you worked so hard to pass on.

In this post, I’ll walk you through everything about when is IHT due, why paying IHT before probate is critical, and how tools like life insurance trusts and whole of life insurance can save your family from probate delays and financial strain. I’ve seen countless families caught off-guard by this; don’t be one of them.
Understanding Inheritance Tax on Property: The Basics
Inheritance tax in the US can hit homeowners hard, especially when the property value pushes past the tax-free threshold. Currently, the inheritance tax threshold is $325,000 per person—that’s the amount you can pass on without triggering the tax man’s bill. For many families with a home valued above this, figuring out how to handle the tax is a must.
Here’s the thing: assuming the home will automatically pass tax-free is a common and costly mistake. It won't. The property will become part of the estate valuation, and guess what? That can mean a hefty inheritance tax bill.
Will your family keep the home - or be forced to sell?
Ever wonder why probate takes so long? Probate is the court-supervised process that validates a will and clears the estate to distribute assets. Unfortunately, it’s not just a delay; it impacts cash flow. The tax man doesn’t wait for probate to wrap up before expecting payment.
In many cases, families face a terrible choice: pay the tax man by selling the home or come up with liquid cash fast. Selling under pressure often means a loss in value, and that’s the last thing you want.
When Is Inheritance Tax Due? HMRC (and US CRA) Deadlines Explained
Let’s break down the timeline simply:
- Inheritance tax becomes due within 6 months of the end of the month in which the person died. So, if your loved one passed on April 15, tax is due by October 31. Interest and penalties kick in for late payments. That means if you miss the deadline, you’re paying the tax man more, not less. The estate cannot be fully distributed until the IHT is paid. This is where probate delays create a cash flow headache.
So, yes, there absolutely is an inheritance tax payment deadline, and it’s one to meet without fail.
Paying IHT Before Probate: What’s the Advantage?
Because probate can drag on for months, sometimes over a year, paying IHT before probate is the best way to save stress and stop the tax man from accruing interest on late payments.

This is where preparation is key. If the estate has enough liquidity (cash or quick assets), the tax can be paid right away, avoiding penalties. If not, that’s where smart estate plans and insurance can step in.
How Life Insurance Can Help You Pay the Tax Man
Most insurers understand the estate stress and offer policies designed for inheritance tax planning. Two popular options include:
- Whole of Life Insurance: This type of policy lasts your entire life and is designed to pay out a lump sum death benefit when you pass. This payout can be used to pay IHT and protect your estate’s value. Life Insurance Trust Forms: Placing your insurance policy into a trust ensures the payout does not become part of your estate (which could incur tax). This way, the funds are available quickly to cover the IHT bill without probate delays.
Setting this up ahead of time is essential. If you wait until the house is about to pass on, it may be too late to avoid delays or tax surprises.
