How do I claim exemption from hotel tax?

Hotel guests claiming exemption by reason of a stay exceeding thirty (30) days shall claim exemption on a standard City form, under penalty of perjury.
Transients claiming exemption by reason of employment as an officer or employee of (1) the U.S. federal government or its instruments (such as federal credit unions or the Red Cross) or (2) a foreign government exempt by express provision of federal law or international treaty shall claim exemption on a standard City form, under penalty of perjury. The officer or employee shall also provide photo identification, proof of his or her governmental employment as an officer or employee, and proof that his or her occupancy is for the official business of his or her governmental employer.
