IHT400: The Inheritance Tax Form You Can’t Afford to Get Wrong

If someone dies and their estate is worth more than £650,000 (that’s two times the current nil-rate band of £325,000), things change.

If it includes a home, you might also be dealing with the residential nil-rate band. Go over these limits, and you’ll need to complete the IHT400 form.

Sounds simple?

It’s not.


The IHT400 Form Is a Monster

This isn’t one form. It’s a pack.

16+ pages. And that’s just the start. Depending on the estate, you might need to include 5, 10, even 15 additional schedules (forms about gifts, properties, pensions, business assets, etc.)

Each section matters. Each number counts.

Guessing? Not an option.


Get It Wrong – and HMRC Will Bounce It Back

That’s right. If you mess up the form or send it in without the right extras HMRC won’t tell you straight away.

You’ll wait weeks.

Then, if you don’t understand what you did wrong, you’re stuck.

And until it’s sorted, the estate stays frozen.

That means:

  • No money released
  • No probate granted
  • No progress

This Is Where I Step In

I offer a simple IHT400 visit and completion service.

Here’s how it works:

✅ I visit you (or we meet online)
✅ I gather the correct info
✅ I complete the IHT400 form
✅ I deal with all the extras IHT403, IHT404, IHT411 etc.
✅ I register the estate with HMRC
✅ I explain what everything means plain English
✅ I show you how to value the estate properly
✅ I help you avoid common mistakes
✅ It’s a fixed-fee service – no hidden charges

This is a service built on experience, not guesswork.


Why Do This?

Because you don’t want delays.
Because you don’t want HMRC rejections.
Because getting it right first time saves everyone time and stress.

This is one of those jobs that seems small but it really isn’t. It can hold everything up.

And when families are grieving, that delay can feel even worse.


Don’t Take the Risk

If you’re handling an estate over £650,000 especially with property involved you will almost certainly need to submit IHT400 and its extra parts.
