I have to give income information for four different time periods on a 21-0516-1 form for my dad (veteran) and his wife. I am referring to the EVR 21-0510 instructions. My dad has STRS (teacher's retirement), and they both have a small amount of Social Security. I painstakingly figured and filled in the total "annual" amounts for the four different time periods in box 7B. I don't know if I am supposed to also list the monthly amounts in box 7A. This is difficult, because the monthly amounts increased slightly over the time periods due to COLA increases. The instructions seem to indicate that if the annual amount is filled in, it is not necessary to fill in the monthly amount. Form 21-0516-1 says to read paragraphs 2 and 3 of EVR instructions to complete box &A and paragraphs 2 and 4 to complete box 7B. Paragraph 2 states: "If you are not sure whether to report income as "monthly income" or "annual income," don't worry. You may report it in either category. The important thing is to report all income, clearly state its source, and not to report the same income twice on the EVR." So should I leave off the monthly income since the annual is filled in? It doesn't seem like a good idea not to fill in this section, but I don't know exactly how to handle. Thanks in advance for any help.
