Has anyone ever encountered having to pay inheritance tax on land purchased?

I never heard of anything like it before, even when I bought my first lot in Philippines.

After what I called being 'conned' into paying for the right of way last year, I now been asked that I still needed to pay an inheritance tax!

I was never aware of this matter. As far as I was concerned, I paid all duties needed for land transaction!

Now I feel like they trying to make more money out of me

Well I hope I'm mistaken, otherwise I will be really pi**ed off

Hope anyone can shed light into this matter for me.

Yours truly,
Pi**ed Tish
