Because housing is expensive in Qatar, the new tax law will cause Americans to have to pay a LOT more in taxes, but many of the employers will provide compensation to make up the difference. Here's a link about this issue: http://www.iht.com/articles/2006/05/25/business/tax.php

Here's one quote: 'Michael Abdalian, a tax partner at Ernst & Young, said he has spoken to many employers about the increased tax burden. "Most companies have programs designed to protect their employees from additional taxes," he said, so the expense will likely be borne by employers.'

So you will have to find out from your employer if they will cover the extra tax. My husband's employer is going to cover it, but we are waiting for his written salary offer to see for sure.
