As any IRS tax lawyer might tell you, some taxpayers can be a little crazy. For someone who deals with taxpayers on a daily basis, many tax professionals will come across those with a myriad of tax issues. Many may keep all of their tax documents and receipts in a shoebox, or worse, a giant moving box. The disorganization is one of the biggest things that tax professionals have to deal with. Since a lot of the time, they won’t be dealing with the paperwork themselves; they can get pretty careless with their organization level.
