Common Questions

Frequently Asked
Questions

Everything you need to know before engaging our team for this service.

Ask Us Directly
How do I know if I have nexus in a state?+
Nexus can be triggered by physical presence, employees, inventory, or economic activity above state-specific thresholds. We conduct a comprehensive nexus study to identify all your filing obligations.
What changed after the Wayfair decision?+
South Dakota v. Wayfair (2018) allowed states to impose tax based on economic activity alone — no physical presence required. If you sell goods or services across state lines, you likely have obligations you are unaware of.
Can you help with unfiled state returns or back taxes?+
Yes — we frequently help businesses catch up on unfiled returns and negotiate penalty abatement and voluntary disclosure agreements with state tax authorities.
Do you handle state tax audits?+
Yes — our CPAs represent clients in state tax audits and appeals across all 50 states, handling all correspondence on your behalf.
