1. Missing or Expired Permits

2. Taxing Resold Items
Charge tax on materials resold to contractors. Fix: Accept & file resale certificates.
3. Not Separating Residential Labor
Tax labor on residential installs. Fix: Invoice separates taxable materials from non-taxable labor.
4. Wrong Nexus Calls
Miss economic nexus thresholds. Fix: Track sales by state. Register when thresholds met.
5. Late or Missed Filings
Penalties + interest accrue. Fix: Set calendar alerts. File even if $0.
6. Vague Invoice Wording
Taxable items not clear → audit risk. Fix: Label taxable items, tax rate, total tax.
7. Mis-Mapped CRM/Operations Items
Items sync wrong → incorrect tax. Fix: Map items to correct tax codes.
8. Use-Tax Gaps
Out-of-state purchases untaxed → use tax due. Fix: Track & report use tax on returns.
9. Ignored Exemptions & Certificates
Miss nonprofit/government exemptions. Fix: Collect & file exemption certificates.
