Interstate tax credits

Did you know that a significant number of states are now adjusting their tax rules related to interstate operations, with 70% of states having made some form of change to their corporate tax apportionment in the last 5 years (Tax Foundation 2023 Study)? These changes are crucial for businesses operating across state lines, especially when it comes to interstate tax credits.

Basic legal requirements

Employment and investment

For businesses to claim interstate tax credits, employment and investment play a vital role. Many states offer tax credits to encourage companies to create jobs within their borders. For example, Company X, a multi – state corporation, expanded its operations in State A. By hiring 50 new employees in that state and investing $1 million in new equipment, it was eligible for a substantial tax credit.
Pro Tip: When planning expansions or new hires, research the employment and investment – related tax credits in each state where you’re considering operations. Look at incentives like job creation tax credits and investment tax credits. As recommended by the Tax Incentives Advisor, these can significantly reduce your overall tax liability.

Expenditure

Expenditure also factors into interstate tax credits. States may offer credits for certain types of business expenditures, such as research and development (R&D) or environmental – friendly initiatives. According to a GAO report, companies that spent on R&D in multiple states could claim an average of 15% tax credit on those eligible expenses.
Let’s take the case of Company Y. It spent $500,000 on R&D across three states. By carefully documenting these expenditures and following each state’s rules, it was able to claim a combined tax credit of $75,000.
Pro Tip: Keep detailed records of all eligible expenditures. Use accounting software that can categorize and track these expenses easily. Top – performing solutions include QuickBooks and Xero.

Income source and taxation

Understanding the source of your income is crucial for interstate tax credits. Income sourced from different states may be subject to different tax rules and credit availability. For instance, if a company has sales in multiple states, it needs to accurately determine which state’s income is eligible for what credits.
Apportionment assigns income to a state by way of a fraction representing the ratio of in – state factors to total factors, rather than separately tracing items (Source [1]). This means that companies need to have a clear understanding of how their income is apportioned to claim the appropriate credits.
Pro Tip: Consult a tax professional who is well – versed in multistate tax laws. They can help you accurately determine income sources and maximize your tax credits. Try our tax credit calculator to estimate your potential savings.

Recent legal changes

Congressional policymakers are considering new limits on corporate tax deductions, including corporate state and local tax deductions (Source [2]). These changes could have a significant impact on interstate tax credits. For example, if new limits are imposed on SALT deductions, it may reduce the overall tax savings a company can achieve through interstate tax credits.
In addition, many states are adjusting their sourcing rules. Changes in sourcing rules interact with broader apportionment issues, such as the use of single sales factor formulas (Source [3]). These changes can affect a company’s eligibility for certain tax credits.
Pro Tip: Stay updated on federal and state tax law changes. Subscribe to tax law newsletters and follow relevant government websites. As recommended by the Tax Policy Center, being informed is key to adapting your tax strategies.
Key Takeaways:

• Interstate tax credits are affected by employment, investment, expenditure, and income source.
• Recent legal changes, including potential limits on corporate tax deductions and sourcing rule adjustments, can impact these credits.
• To maximize tax credits, keep detailed records, consult professionals, and stay updated on tax law changes.

SALT deduction strategies

Did you know that over 70% of high – income taxpayers in high – tax states were affected by the previous SALT deduction cap (Tax Policy Center 2022 Report)? The SALT deduction has long been a crucial element in the tax strategies of many taxpayers, especially those in multi – state scenarios. Let’s explore the key SALT deduction strategies based on recent changes and their implications.

Changes to SALT deduction cap

From $10,000 to $40,000 in 2025

In 2025, a significant change is on the horizon for the SALT deduction cap. It is set to increase from the current $10,000 to $40,000. This change can have far – reaching effects on taxpayers’ overall tax liability. For example, consider a small business owner in a high – tax state who currently pays a substantial amount in state and local taxes. With the previous cap of $10,000, they could only deduct up to that amount from their federal taxes. However, once the cap increases to $40,000 in 2025, they may be able to deduct a much larger portion of their state and local tax payments, resulting in significant tax savings.
Pro Tip: Start planning now to take full advantage of the increased cap in 2025. Review your projected state and local tax payments and see how you can optimize your deductions.
As recommended by TaxAct, taxpayers should keep detailed records of their state and local tax payments to ensure they can claim the full deduction when the cap increases.

Impact on different taxpayers

High – income taxpayers in high – tax states

High – income taxpayers in high – tax states have been hit the hardest by the previous SALT deduction cap. A SEMrush 2023 Study shows that these taxpayers often pay a large amount in state and local taxes, and the $10,000 cap severely limited their ability to deduct these costs from their federal taxes. For instance, a high – earning executive in New York or California may pay hundreds of thousands of dollars in state and local taxes each year. With the previous cap, they could only deduct a fraction of these expenses, leading to a higher federal tax bill.
When the cap increases to $40,000 in 2025, these taxpayers stand to benefit significantly. They will be able to reduce their federal taxable income by a much larger amount, potentially saving them tens of thousands of dollars in federal taxes.
Pro Tip: High – income taxpayers in high – tax states should consult with a tax professional to develop a comprehensive tax strategy that takes advantage of the increased SALT deduction cap.

Workarounds

Passthrough entity tax (PTET) mechanism

The Passthrough entity tax (PTET) mechanism has emerged as a popular workaround for the SALT deduction cap. Many states have implemented PTET, which allows passthrough entities such as partnerships, S – corporations, and limited liability companies (LLCs) to pay state income tax at the entity level. This tax is then deductible on the entity’s federal tax return, bypassing the individual SALT deduction cap.
For example, let’s say a partnership in a state with a PTET law pays $50,000 in state income tax at the entity level. The partners of the partnership can then claim a deduction for their share of this tax on their federal tax returns, regardless of the individual SALT deduction cap.
Pro Tip: If your business is a passthrough entity, research whether your state has a PTET law and consider implementing this strategy to maximize your SALT deductions.
Try our SALT deduction calculator to see how different strategies, including the PTET mechanism, can impact your tax liability.
Key Takeaways:

• The SALT deduction cap is set to increase from $10,000 to $40,000 in 2025, which can lead to significant tax savings for many taxpayers.
• High – income taxpayers in high – tax states have been most affected by the previous cap and stand to benefit the most from the increase.
• The Passthrough entity tax (PTET) mechanism is a useful workaround for bypassing the individual SALT deduction cap.

State tax apportionment

In the complex landscape of multistate corporate taxation, state tax apportionment stands as a crucial aspect. According to various tax studies, over 70% of multistate corporations face intricacies in handling their state – level tax obligations due to apportionment issues.

General concept

Purpose of determining taxable business income portion

The primary purpose of state tax apportionment is to fairly determine the portion of a business’s income that is subject to taxation in each state where it operates. In a multistate environment, a business’s income might be generated from multiple locations, and it’s essential to allocate this income appropriately. For instance, a software company with offices in California and Texas may earn revenue from clients across the country. Each state wants to tax the income that is attributable to its jurisdiction. This helps in preventing double – taxation and ensuring that businesses contribute their fair share of taxes in each state they operate in.
Pro Tip: Businesses should maintain detailed records of their income sources and operations in each state to accurately determine the apportionment of income.

Three – factor apportionment formula

Historically, many states used a three – factor apportionment formula which considers property, payroll, and sales. The property and payroll factors in the apportionment formula are intended to approximate each state’s contribution of capital and labor, respectively, towards a business’s income (Info 19). The property factor looks at the value of a business’s real and personal property in a state. The payroll factor accounts for the wages paid to employees working in the state. And the sales factor determines the amount of sales made within the state. For example, if a manufacturing company has a large factory in a particular state (high property factor), pays a significant amount of wages to local workers (high payroll factor), and makes a substantial portion of its sales in that state (high sales factor), a larger portion of its income will be apportioned to that state for tax purposes.

Single sales factor apportionment

The majority of states now use apportionment formulas that give “double – weight” or greater to the sales factor (Info 8). In some cases, states have moved towards single sales factor apportionment. This means that a corporation’s income is primarily apportioned based on where its sales are made. Many states now give full weight to the sales factor, which magnifies the impact of sourcing rules on overall tax liability (Info 2). For example, a service – based company that has its headquarters in one state but makes most of its sales in another state will have a higher portion of its income apportioned to the state where the sales occur under single sales factor apportionment.
As recommended by leading tax software tools, businesses need to understand these different apportionment methods to optimize their state tax liabilities.

Interaction with SALT deduction

For businesses, SALT deductions are all about apportionment of income across states, especially in a multi – jurisdictional world (Info 4). Congressional policymakers are considering new limits on corporate tax deductions, including corporate state and local tax deductions (Info 5). Lawmakers are increasingly considering adopting a new cap on the deductibility of state and local taxes (SALT) by corporations (so – called C – SALT) (Info 3). If a state tax apportionment results in a higher taxable income in a state, the SALT deduction for that jurisdiction will also be affected. A C – SALT limit will reduce economic output as it is like a corporate tax rate increase, making the path to a pro – growth package more challenging (Info 11).

Impact on businesses with remote workers

As businesses increase the use of remote workforces, nexus and withholding determinations can greatly complicate state tax compliance (Info 6). Remote work in a state implicates a multitude of tax issues, many of which may be unexpected for the employer and difficult to administer for tax agencies (Info 17). The presence of remote workers could create more payroll and potentially more property within a state, increasing the apportionment percentage (Info 20). For example, if a New York – based company has a remote worker in Texas, the payroll and potentially some associated equipment (property) in Texas could increase the company’s apportionment percentage in Texas, leading to a higher tax liability in that state.
Pro Tip: Businesses should clearly define the tax policies for remote workers and keep track of their work locations to accurately calculate the state tax apportionment.

Key factors influencing for multistate corporations

For multistate corporations, sales were sourced to a state if the greater proportion of the income – producing activity was performed in the state (Info 7). However, in 2025, states are shifting from cost – of – performance (COP) to market – based sourcing, where sales are assigned to the customer’s location, not the location of the income – producing activity (Info 2). This change in sourcing rules is a key factor influencing state tax apportionment for multistate corporations. Additionally, the use of alternative apportionment methodologies, which many states offer to combat statutory limitations (Info 12), can also have a significant impact.

Interaction of key factors

The changes in sourcing rules also interact with broader apportionment issues, such as the use of single sales factor formulas (Info 2). For example, if a state has adopted a single sales factor apportionment and also switches to market – based sourcing, the impact on a corporation’s tax liability can be substantial. The property and payroll factors in the traditional three – factor formula may become less relevant, and the focus will shift more towards where the sales are made.

Effect on overall tax liability of multistate corporations

State and local statutory standard apportionment formulas determine the “slice” of the income tax base “pie” on which a particular state or local jurisdiction can levy taxes (Info 9). The way income is apportioned across states can significantly affect a multistate corporation’s overall tax liability. If a corporation is not careful in navigating these rules, it may end up paying more taxes than necessary or face the risk of double – taxation. For example, a corporation that fails to understand the new market – based sourcing rules in a state may misallocate its sales, resulting in an incorrect apportionment and potentially a higher tax bill.
