A Form 1099-MISC is required to be issued only by a business that pays $600 or more to an independent contractor. If your rental activity is only an investment and not a business, you don’t have to issue a 1099. (There has been a law change several years ago that would have required investors to issue 1099s, but that law never went into effect and was ultimately repealed.)
A 12-month period ending on the last day of any month other than December. Partnerships, S corporations, and personal service corporations are limited in their choice of fiscal years and face special restrictions.
