Our Services


We will analyze your financial and tax situation to formulate solutions and make recommendations designed to provide advice on taxation for both individuals and businesses.


While most consider income taxes first when they think of tax service, Simple Sums Accounting understands that there are over 9,000 different taxing authorities in the United States and your needs may include sales and use taxes, excise taxes, payroll taxes, or property taxes. Teresa has experience in filing taxes in multiple states and jurisdictions as well as researching tax notices and reviewing previously returned files.

My approach is simple-collaboration on your terms to provide GAAP standard accounting while remaining sensitive to your individual business needs.
