Taxation in Puerto Rico

Bona fide residents of Puerto Rico cannot claim deductions and/or credits allocable to or chargeable against Puerto Rican source income that is excluded from a U.S. tax return. The deductions and credits not attributable to specific income must be divided between excluded income from sources in Puerto Rico and income from all other sources to find the part that can be deducted or credited on a U.S. tax return. Examples of deductions not attributable to specific income include alimony, the standard deduction, and certain itemized deductions such as medical expenses, charitable contributions, and real estate taxes and mortgage interest on your personal residence. Personal exemptions are generally allowed in full.
