Father (88) gifts/loans son money - IHT question

I am not clear that you would have to pay the IHT on the gift.

If there are sufficient funds to pay all IHT liabilities in the estate of the person who dies, does a person who receives a gift have to pay IHT tax? I have googled this question and I am still unclear.

In the long run, if the money's given back to his account and isn't spent, tax will still have to be paid if it's passed on to me. But I agree, get it typed up and signed, and kept up to date is the best method.
No point in keeping quiet...I want to keep everything up front and unquestionable, won't want any hassle at an upsetting time.
Think I'll accept it as a gift and simply add it on to the form when the time comes, if he lives a while then IHT will be reduced on it anyway.
Will keep all the paperwork r/e the two cars receipts of course. Thanks!!

A gift is not a loan. If it's a loan, type up a written agreement that you both sign with a repayment schedule, keep a record ( and proof) of repayments made and then if he dies before the total is repaid, you will owe the balance to the estate. or just keep quiet about it - will anyone ever know

**Note, he's 88 shortly - in the new tax year!!
