Local & State Tax Planning

Navigating an Increasingly Complex Tax Environment

State and local taxes are one of the most complex, rapidly evolving, and frequently overlooked areas of business taxation. Nexus rules are expanding, remote workforces are creating unexpected multi-state obligations, and the patchwork of sales and use tax requirements across jurisdictions creates exposure that grows quietly in the background until a state auditor finds it first. Strategic SALT planning helps businesses identify hidden liabilities, achieve compliance across all applicable jurisdictions, and implement strategies that reduce their overall state and local tax burden.

Frequently Asked Questions

What is state and local tax (SALT) and why does it matter for my business?

State and local tax refers to the full range of taxes imposed by state and local governments, including state income and franchise taxes, sales and use taxes, payroll taxes, property taxes, and various other levies that vary significantly by jurisdiction. SALT matters for your business because these obligations are not always obvious — nexus rules, economic thresholds, and apportionment requirements create tax obligations in states where you may not even realize you are doing business. The consequences of unaddressed SALT exposure include back taxes, penalties, and interest that can accumulate over multiple years before they are discovered — making proactive SALT analysis one of the most valuable investments a business can make.
What is nexus and how does it affect my business?

Nexus is the legal term for the connection between your business and a state that is sufficient to create a tax obligation in that state. Nexus can be established in a variety of ways — through a physical location, employees or independent contractors working in a state, ownership of property, or simply by exceeding an economic threshold of sales into a state (known as economic nexus). Since the Supreme Court’s 2018 South Dakota v. Wayfair decision, economic nexus has dramatically expanded the number of states in which many businesses have sales tax obligations — often without the business realizing it. Yeo & Yeo’s nexus analysis identifies where your business has established nexus, what type of tax obligations that creates, and what steps are needed to achieve compliance.
What are the state and local tax implications of having remote employees?

Remote employees create multi-state tax complexity across several categories simultaneously. An employee working from home in another state can create income tax nexus for your business in that state, payroll tax withholding obligations in the employee’s state of residence, and in some cases sales tax nexus as well. Many businesses that rapidly expanded remote work arrangements during and after the pandemic created unintended multi-state tax obligations that have been quietly accumulating ever since. Yeo & Yeo helps businesses assess the full multi-state tax impact of their remote workforce, establish compliant payroll and income tax processes in all affected states, and address any historical exposure that may have accumulated.
How does state and local tax planning connect to business growth and expansion decisions?

Every time your business expands into a new market, adds employees in a new state, acquires another business, or launches a new product or service, the state and local tax implications of that decision should be evaluated in advance. The cost of unmanaged SALT exposure — in back taxes, penalties, interest, and administrative burden — can meaningfully erode the financial benefits of a growth initiative that was not fully tax-planned. Yeo & Yeo’s SALT specialists work alongside our business tax and advisory teams to assess the state and local tax implications of major business decisions before they are made — so you pursue growth opportunities with full visibility into their tax consequences and a clear plan for managing them.
