At Sorren, we partner with enterprises to help them confidently navigate the complex landscape of state and local tax obligations. For businesses operating in multiple states, January is the ideal time to review and strengthen SALT compliance strategies. State-specific tax laws are ever-changing, making a proactive approach crucial for managing risk and supporting financial health.
This guide will help you understand the pillars of SALT compliance—demystifying nexus rules, highlighting effective compliance strategies, and offering actionable steps to ensure your business is prepared for the year ahead. Taking the time to examine your SALT process now helps prevent costly surprises and supports seamless operations as your company grows.
Tax Nexus: The Foundation of SALT
The concept of nexus is central to state and local tax compliance. Nexus refers to the connection that obligates your business to comply with a state’s tax requirements. Traditionally, this was defined by physical presence—such as offices, warehouses, or employees. However, following the Supreme Court’s South Dakota v. Wayfair, Inc. decision in 2018, most states have adopted “economic nexus” standards.
Now, surpassing state-specific sales thresholds or the number of transactions alone—even without any physical presence—can trigger tax obligations. For example, just $100,000 in annual sales or 200 transactions can establish nexus in certain states. The rise of remote work further complicates this: an employee working from another state—even temporarily—can create income, sales, and payroll tax obligations for your company.
Given these complexities, companies should regularly review all activities that could potentially establish nexus, including employee locations, remote work arrangements, shipments, service delivery, and relationships with affiliates and contractors.
Smart SALT Compliance Strategies
SALT compliance is not a task to approach reactively. Forward-thinking enterprises engage in ongoing monitoring and strategic management to minimize risk, ensure timely filing, and avoid avoidable penalties. Here’s how your organization can take control:
1. Conduct a Thorough Nexus Study
At the beginning of each year, undertake a detailed review of your business footprint. Map out all states where your business conducts sales, has employees (both in-office and remote), holds inventory, utilizes warehouses, or works with third-party contractors. Track both physical and economic nexus triggers. This process helps you spot new or evolving exposures early, giving you lead time to address compliance issues before they result in costly assessments or audits.
2. Leverage Technology for Accurate Tracking
Modern tax compliance demands software that can keep pace with shifting variables. Tax compliance solutions can automatically track sales thresholds, update tax rates, and generate accurate filing data for hundreds or thousands of jurisdictions. Integration with ERP and e-commerce platforms ensures that your records remain current and minimizes manual effort, reducing the risk of data entry errors and missed obligations. At Sorren, we recommend investing in scalable tax tech now—setting your team up for efficiency and peace of mind all year long.
3. Stay Ahead of Regulatory Changes
State tax laws, nexus thresholds, and filing requirements can change rapidly, especially as states seek new revenue sources and update their regulations in response to remote work trends. Assign responsibility within your finance or compliance team to regularly monitor legal updates in all relevant jurisdictions. Subscribe to reputable industry newsletters, set up compliance alerts, and schedule quarterly check-ins with your tax advisors. Being proactive in policy monitoring helps you respond quickly to new obligations and avoid exposure to fines or back taxes.
4. Actionable Steps for the Year Ahead
- Schedule a Comprehensive Nexus Review: Make this an annual event. Engage both internal teams and experienced advisors to map your nexus footprint and identify new obligations.
- Evaluate and Enhance Technology: Take stock of your current tax software. Is it capable of real-time compliance and reporting across jurisdictions? If gaps exist, identify and implement upgrades early in the year.
- Revisit Remote Work and Mobility Policies: Synchronize with HR and legal to document employee and contractor locations, including flexible or temporary arrangements. Know where your people are—and how that impacts your SALT exposure.
- Create a Centralized Compliance Calendar: Develop a detailed calendar listing filing deadlines for all relevant states (sales, income, franchise, use taxes, and more). This tool helps keep your finance team organized and on track.
- Consult with SALT Experts: Situations involving historical non-compliance, M&A activity, or international expansion require specialized insight. Sorren’s tax professionals help interpret nuanced state rules and, where needed, guide you through voluntary disclosure to resolve past obligations as favorably as possible.
