Who can I contact to help me figure out which forms to use and how to fill it our? Husband always took care of this stuff but he died recently and I don't even know if I need to file.

Many Americans merely use a tax service, such as HR Block, Liberty and others. Other people with more complex taxes will hire and use a CPA. There are even programs, such as Turbo Tax, ( and many others) that ask you sort of fill in the blank questions to do your taxes

Excellent help! Love the sites you provide. Thank you for your help in this matter.
