Well that's news to me and yeah I am seeing this policy on the IRS website ("You can claim only the number of allowances to which you are entitled."). Multiple third party websites say you can effectively claim whatever number of allowances you want as long as you pay your taxes by the due date and withhold enough to qualify for waiving underpayment penalties. It appears this is not a frequently enforced law by the IRS and there is a lot of estimation involved anyway. I guess I'll just claim the maximum number of allowances I can justify and let Uncle Sam have a free loan. Thanks!
