First - you have to mention what the syndication will do as that will have an impact on how you get taxed.Given that this is a real estate forum, it is assumed that you are investing in a syndication that will invest in real estate.Most real estate syndications purchase real estate in year 1 and have a plan of selling / exiting in year 5 or 7.Often times, the sponsor will get a cost segregation study which increases the loss on the K-1 presented to the investor in year 1.This may be important as it almost guarantees that there will be no taxable income from the syndication from year 1 to the year before exit.If the syndication does well and exits at a price more than purchase, it may result in a taxable income.
