request for tax forms question

my 12/15 lax application received a response early morning 1/11 (saturday) which i find strange given the weekend and very early hours; these are processed locally by the embassy and not in thailand (which would also have been saturday night) right?

in any case, they asked for business registration info, last year's taxes, and a business portfolio. not sure what i'll provide for the last as i don't 'publicly make things' - in any case my big question is about the taxes. i'd rather not be out here sharing my tax filings with anyone, is there any way people have used to avoid this but met some kind of income/economic viablility request without sharing tax forms?
