“Your housing amount is the total of your housing expenses for the year minus a base amount.
The base amount is 16% of the annual salary of a GS-14, step 1, U.S. Government employee, figured on a daily basis, times the number of days during the year that you meet the bona fide residence test or the physical presence test. The annual salary is determined on January 1 of the year in which your tax year begins.”
Stupid friggin taxes…
