Build a state-activity summary for your tax adviser

A company's formation state and mailing address do not describe every place it operates. Prepare a state-by-state summary of employees, offices, inventory, contractors, services, and sales activity. Keep legal registration, payroll, income tax, sales tax, and other obligations as separate questions for the relevant adviser.

Do not label the entire row no nexus because one tax threshold appears unmet. Different obligations can use different rules and exceptions. The summary's job is to supply reliable facts, not to turn one internet threshold into a universal conclusion.

For each activity, identify the legal entity, location, start and end dates, and supporting source. An employee move, a new warehouse, or a temporary project can change the picture during the year. Preserve history instead of replacing the old address with the current one.

For ecommerce, ask fulfillment providers where inventory was stored and when. For service businesses, obtain work-location facts from the people responsible for staffing and delivery. A customer billing address or a corporate headquarters list may be incomplete evidence for the question the adviser is assessing.

Provide sales by relevant destination and period using the definitions requested by the specialist. Distinguish direct sales from marketplace activity and retain evidence of taxes collected or remitted by another party. Marketplace involvement does not automatically settle every registration, filing, or other tax question.

Reconcile the sales summary to the underlying order or invoice population and explain exclusions, returns, and currency conversion. If the data is incomplete, identify the limitation rather than filling missing states with zeros. A zero and an unknown are different inputs to a tax review.

Ask the adviser to document the requirements assessed, jurisdictions, relevant periods, assumptions, and follow-up actions. Keep the authoritative state guidance or professional memo with the conclusion. A filing calendar should identify who registers, prepares, approves, submits, and pays where required.

Refresh the activity summary when the business changes, not only after year-end. Route new locations, worker moves, and fulfillment arrangements to the responsible reviewer before activity begins where practical. Keep prior conclusions dated so the company can tell which facts they were based on.
