If you run a business in the United States, you are not only dealing with federal taxes.
You also need to understand state and local taxes, commonly known as SALT. These taxes can have a major impact on your business operations, profitability, and compliance obligations.
Unlike federal taxes, SALT rules vary depending on where your business operates. Each state and even local jurisdictions like cities or counties may have their own tax laws, rates, and filing requirements.
This makes tax compliance more complex, especially if your business operates in multiple states.
Many business owners underestimate how important SALT is. However, failing to understand or comply with these taxes can lead to penalties, audits, and unexpected financial liabilities.
SALT includes a wide range of taxes such as income tax, sales tax, property tax, and payroll-related taxes. Each of these taxes applies differently depending on your business structure and location.
In this guide, you will learn what State and Local Tax (SALT) is, how it affects your business, and how to manage compliance effectively.
What Is State and Local Tax (SALT)?
State and Local Tax (SALT) includes all taxes that are levied at the state and local levels. These taxes are used to fund public services such as education, infrastructure, public safety, and transportation.
For business owners, SALT is important because it directly affects your financial obligations and compliance requirements.
Common types of SALT include:
- Income taxes on business profits
- Sales taxes on goods and services
- Property taxes on real estate and equipment
- Payroll-related taxes
Because each state sets its own tax rules, your obligations can differ significantly from one location to another.
Types of State Taxes
State governments impose several types of taxes that can affect your business.
- State income tax: Many states tax business income. The rate and structure vary depending on the state and your business entity type.
- State sales tax: Sales tax is applied to the sale of goods and, in some cases, services. Businesses are responsible for collecting and remitting this tax to the state.
- State franchise or business taxes: Some states impose franchise taxes or other business-specific taxes based on revenue, capital, or net worth.
Each state has its own rules, which means you must understand the requirements in every state where your business operates.
Types of Local Taxes
In addition to state taxes, local governments may also impose their own taxes.
These can include:
- City or county taxes: Some cities and counties impose additional income or business taxes on top of state taxes.
- Local sales taxes: Local jurisdictions may add their own sales tax rates, increasing the total tax collected from customers.
- Property taxes: Local governments typically assess property taxes on real estate and business assets such as equipment.
Local taxes can vary even within the same state, which adds another layer of complexity for business owners.
Understanding both state and local taxes is essential if you want to stay compliant and avoid costly mistakes.
Why SALT Matters for Business Owners
Understanding SALT is not just about knowing what taxes exist.
It is about recognizing how these taxes affect your business operations, finances, and compliance responsibilities.
If you ignore SALT or misunderstand your obligations, it can lead to serious consequences such as penalties, audits, and unexpected tax liabilities.
1. Compliance Requirements
One of the biggest reasons SALT matters is compliance.
Each state and local jurisdiction has its own tax rules, filing deadlines, and reporting requirements. As a business owner, you are responsible for understanding and meeting these obligations.
For example, you may need to:
- Register for sales tax permits in different states
- File state income tax returns
- Remit collected sales taxes on time
- Maintain proper records for audits
Failing to comply with these requirements can result in fines or legal issues.
2. Financial Impact on Businesses
SALT can have a direct impact on your business’s profitability.
Taxes such as income tax, sales tax, and property tax can significantly affect your cash flow. If you do not plan for these expenses properly, they can reduce your margins and create financial strain.
For example:
- Higher state income taxes can reduce net profits
- Sales tax obligations can increase administrative costs
- Property taxes can affect long-term investments
Understanding these costs allows you to budget more effectively and avoid surprises.
3. Multi-State Operations and Complexity
If your business operates in more than one state, SALT becomes even more complex.
You may have tax obligations in multiple jurisdictions, each with its own rules. This can happen even if you do not have a physical presence in a state.
For example, selling products online to customers in different states may create tax obligations in those states.
This complexity makes it important to track where your business activities occur and understand how they trigger tax responsibilities.
Managing SALT effectively helps you stay compliant, reduce risks, and make better financial decisions for your business.
Key Components of SALT for Businesses
To manage State and Local Tax effectively, you need to understand the key components that apply to your business.
SALT is not a single tax. It is a combination of different taxes that can affect your business in multiple ways.
Each component has its own rules, rates, and compliance requirements.
1. Income and Franchise Taxes
State income taxes apply to the profits your business earns.
Depending on your business structure, these taxes may be paid at the business level or passed through to owners.
Some states also impose franchise taxes, which are not based on profit but on factors such as revenue, capital, or net worth.
These taxes can vary significantly by state. For example:
- Some states have high income tax rates
- Others may not have income tax, but impose franchise taxes instead
Understanding how each state taxes income is essential for accurate financial planning.
2. Sales and Use Taxes
Sales tax is one of the most common SALT obligations for businesses.
If you sell goods or certain services, you may be required to:
- Collect sales tax from customers
- Report and remit that tax to the appropriate state or local authority
Use tax applies when sales tax is not collected at the time of purchase. Businesses may need to pay use tax on certain out-of-state purchases.
Sales tax rules can be complex because:
- Rates vary by state and locality
- Some products or services may be exempt
- Filing frequencies differ by jurisdiction
Managing sales and use tax properly is critical to avoiding penalties.
3. Property Taxes
Property taxes are typically imposed by local governments and apply to both real estate and business property.
This includes:
- Office buildings or retail spaces
- Equipment and machinery
- Land owned by the business
Property taxes are based on the assessed value of the property. Local authorities determine this value and apply a tax rate.
For businesses with significant assets, property taxes can be a major expense.
4. Payroll and Employment Taxes
If you have employees, you are responsible for certain state-level payroll taxes.
These may include:
- State unemployment insurance taxes
- State income tax withholding
- Other employment-related taxes
As an employer, you must:
- Withhold the correct amount from employee wages
- Report wages to state agencies
- Remit taxes on time
Failure to meet payroll tax obligations can result in penalties and compliance issues.
What Is Nexus and Why It Matters
When dealing with State and Local Tax, one of the most important concepts you need to understand is nexus.
Nexus determines whether your business has a tax obligation in a particular state.
In simple terms, nexus means a connection between your business and a state. If that connection exists, the state can require you to collect taxes or file returns.
Understanding nexus is essential because it directly affects where and how you pay taxes.
1. Physical Nexus
Physical nexus occurs when your business has a physical presence in a state.
This can include:
- An office or store location
- A warehouse or inventory storage
- Employees or representatives working in the state
If your business has any of these, you likely have a tax obligation in that state.
For example, if you open a retail store in another state, you will generally need to collect sales tax and comply with that state’s tax laws.
2. Economic Nexus
Economic nexus is based on your business activity in a state, even if you do not have a physical presence there.
You may create an economic nexus if your business exceeds certain thresholds, such as:
- A specific amount of sales in a state
- A certain number of transactions
This means that even online businesses selling products to customers in different states may have tax obligations in those states.
Economic nexus rules have made SALT compliance more complex, especially for e-commerce businesses.
Impact of South Dakota v. Wayfair
A major change in SALT rules came from the Supreme Court decision in South Dakota v. Wayfair (2018).
Before this case, businesses generally needed a physical presence in a state to be required to collect sales tax. After the decision, states were allowed to enforce economic nexus rules.
This means that businesses can now have tax obligations in states where they only have sales activity, even without a physical presence.
Understanding nexus is critical because it determines where your business must register, collect taxes, and file returns.
Strategies to Manage SALT Effectively
Managing State and Local Tax can feel overwhelming, especially if your business operates in multiple states.
However, with the right approach, you can stay compliant and reduce risks.
The key is to be proactive and organized.
1. Maintain Accurate Records
Accurate record-keeping is one of the most important parts of managing SALT.
You should maintain detailed records of:
- Sales transactions by state
- Tax collected and remitted
- Business expenses and income
- Payroll and employee information
Keeping organized records helps you:
- File accurate tax returns
- Respond to audits more effectively
- Track your tax obligations across different states
Using accounting software or digital systems can make this process easier and more efficient.
2. Use Tax Technology Solutions
Technology can play a major role in simplifying SALT compliance.
Many businesses use tax software to:
- Calculate sales tax automatically
- Track nexus thresholds
- Generate reports for filing
- Manage multi-state tax obligations
These tools reduce manual errors and save time, especially as your business grows.
For example, automated systems can update tax rates in real time, ensuring that you always apply the correct rates for each jurisdiction.
3. Work With Tax Professionals
SALT regulations can be complex and constantly changing. Working with a tax professional can help you stay compliant and avoid costly mistakes.
A tax advisor can help you:
- Understand your obligations in different states
- Identify potential tax risks
- Plan strategies to reduce tax liabilities
- Prepare and file tax returns accurately
Professional guidance is especially valuable if your business operates in multiple states or has complex tax requirements.
By combining accurate records, technology, and expert advice, you can manage SALT more effectively and focus on growing your business.
Conclusion
Understanding State and Local Tax is essential if you want to run your business successfully in the United States.
SALT affects many areas of your business, from income and sales to property and payroll taxes. Without a clear understanding of these obligations, it can be easy to fall behind on compliance or face unexpected costs.
As your business grows, SALT can become more complex, especially if you operate in multiple states or sell products across state lines.
Concepts like nexus and varying state tax rules make it important to stay informed and organized.
However, navigating SALT regulations on your own can be challenging. This is where professional guidance can make a significant difference.
