Due to illness, I am going to miss the extended deadline for a partnership return (form 1065, normal extended deadline September 15) and most likely also the extended deadline for form 1040 (October 15). Please, what should I do? Write the IRS with some medical documentation? Or something else? If letters, what address for the 1065 and what address for the 1040, please?
Thanks in advance, any help appreciated.
