Businesses sometimes discover that they have unpaid sales tax obligations after operating for several years. This situation may occur when nexus thresholds were exceeded but tax was not collected or when tax reporting errors occurred.
Resolving sales tax liabilities requires businesses to evaluate the scope of the issue, determine which states are involved, and take corrective actions to address the unpaid tax.
Understanding how businesses resolve sales tax liabilities helps companies address compliance issues before penalties and interest increase further. If you are unfamiliar with sales tax exposure, begin with the guide: How Businesses Create Sales Tax Exposure
Identify the Scope of the Liability
The first step in resolving sales tax liabilities is identifying the extent of the exposure.
Businesses should review historical sales activity to determine
- When nexus was first created
- Which states were affected
- Total taxable sales during the exposure period
This analysis helps estimate the amount of unpaid tax that may be owed.
To review nexus thresholds across states, visit: Economic Nexus by State. Businesses can estimate exposure using the Sales tax exposure calculator.
Register for Sales Tax
Once the scope of the liability is identified, businesses typically must register for sales tax in the affected states. Registration allows the business to begin collecting tax on future transactions and comply with reporting requirements.
The registration process usually involves:
- Submitting a sales tax permit application
- Receiving a tax permit number
- Beginning tax collection
- Filing tax returns according to state requirements
More details about registration are explained in How to Register for Sales Tax.
Calculate Historical Tax Obligations
After registration, businesses may need to calculate unpaid sales tax for prior periods.
This calculation typically involves:
- Identifying taxable sales during the exposure period
- Applying the correct tax rates
- Calculating interest and penalties
The resulting amount represents the tax liability that must be resolved with the state. More details about liability calculations are explained in How to Calculate Historical Sales Tax Liability.
Voluntary Disclosure Programs
Many businesses resolve sales tax liabilities through voluntary disclosure agreements. These programs allow businesses to report unpaid tax liabilities before an audit occurs.
Voluntary disclosure programs may offer benefits such as
- Limiting the lookback period for unpaid taxes
- Reducing or eliminating penalties
- Resolving compliance issues before enforcement actions begin
More details about voluntary disclosure programs are explained in Sales Tax Voluntary Disclosure Agreements Explained.
Audit Resolution
If tax authorities have already initiated an audit, businesses must resolve liabilities through the audit process.
This may involve:
- Providing financial records
- Reviewing auditor calculations
- Negotiating adjustments to tax assessments
- Paying assessed liabilities
More details about the audit process are explained in What Happens During a Sales Tax Audit.
Preventing Future Liabilities
Once tax liabilities are resolved, businesses should implement procedures to prevent future compliance issues.
Important steps include:
- Monitoring nexus thresholds regularly
- Tracking revenue by state
- Reviewing inventory storage locations
- Maintaining accurate tax reporting systems
Proactive compliance helps businesses avoid future exposure and penalties.
