@bluespirit - Tax analysts are a type of accountant, but not all accountants are tax analysts. The person that does your husband's taxes is a tax preparer, not an analyst. Tax preparers merely translate the financial results of a given period onto the tax return. A tax analyst influences the business' policies on an ongoing basis in order to save taxes in addition to preparing tax returns.
There are other types of accountants who don't do any type of tax work at all, such as auditors and bookkeepers.
