How We Work
From Your Books to a Filed Return
A business tax return is only as accurate as the financial records behind it. We work directly from your bookkeeping records — whether maintained by you, your bookkeeper, or our firm — reconciling and reviewing them before preparation begins. If we identify classification issues or inconsistencies, we flag them and work with you to resolve them before filing.
Review Your Financial Records
We start by reviewing your income statement, balance sheet, and supporting documentation to understand your business activity for the year.
Identify Deductions and Issues
We look for deductible expenses, flag any classification questions, and identify anything that needs clarification before the return is prepared.
Prepare and Review the Return
We prepare your federal and state returns, review them for accuracy and completeness, and walk you through the results before filing.
File and Plan Ahead
Once approved, we file your return and discuss any planning opportunities or estimated tax obligations for the coming year.
