Does your business sell to customers across state lines or employ remote workers in multiple states? You may have more tax exposure than you realize. In this audio blog, Maria Gordon, Tax Manager at CK, breaks down the concept of state Nexus, the legal connection that can trigger sales, income, and payroll tax obligations in states beyond your own. Learn the four key factors that create Nexus, how apportionment determines your tax liability across states, and practical steps you can take to stay ahead of multi-state tax compliance before it becomes a costly surprise.
Transcript:
Hello, my name is Maria Gordon. I am a tax manager at Cray Kaiser and I have been with the firm for nine years. I would like to talk today about state Nexus for multi-state companies. If your business has customers throughout the U.S. or remote employees working in various states, you may have wondered about the implications of multi-state taxation or maybe you’ve even worried that you might owe tax in states and not realize it. With each state having its own guidelines, accurately determining your business’ state exposure is quite a complex undertaking. Businesses need an advisor with an in-depth knowledge of the tax laws of every state and the various complexities in determining Nexus for both sales tax and income tax.
So let’s start on this. To determine whether your business has exposure in a state, we must consider Nexus. Nexus is just a legal level of connection with a state that gives that state the authority to tax your business, whether it be sales tax or income tax. So in determining if Nexus exists, we look to four general areas. The first of these would be the amount of revenues that you have in a state, and once certain thresholds are reached, your business could be liable for sales tax, income tax, or franchise taxes. And the second one being whether your business has property in a state or holds inventory stock within that state. These things automatically give you physical presence in the state and could subject you to taxes. The third of these is whether you have employees, sales reps, or other remote employees working in a state. And finally, the fourth item, for some states, simply being registered to do business in the state will result in Nexus.
Now, with the ever-expanding remote workforce, this impacts many companies. Even a single employee in a state gives your business a tax presence, and you could be subject to sales tax, payroll tax, and income tax. To add more difficulty to this, state taxes can depend on where the employee lives and where the employee works, which are not always the same state. Some states do have agreements with one another to simplify payroll tax reporting of remote workers, but then again many states do not. If you do determine that your business has Nexus in a state, it doesn’t necessarily mean you will pay tax on 100% of your income to that state. Instead of just subjecting all of your income, each state uses apportionment to determine its portion of the pie, as you will. Apportionment is a formula based on the amount of sales, property, and payroll in the state. Of course, each state has their own formula for apportionment with varying weight on each of these three factors, but the sales factor is generally the most important. Speaking of the sales factor, how do I identify where revenues occur? With a business that sells widgets and ships them around the U.S., it’s quite simple. Each sale is attributed to the state that the widget was shipped to. But what if your business provides intangibles such as computer software or if your business provides services? Each state uses either a market-based approach or a cost-of-performance approach. Under market-based sourcing, revenues are sourced to the state where the benefit of the intangible or service is received. And under cost-of-performance, revenues are sourced to the state where the work is performed. So these differences are quite important between the states and a business needs to understand how they’re going to source their revenues.
If all of this feels daunting, don’t worry. It is possible to stay on top of Nexus requirements and protect your business from unexpected tax bills. Some things to consider. If it has been a while since you’ve considered your company’s footprint across the states, Cray Kaiser can help with providing a Nexus study. This will show you where the company has Nexus and open up the discussion on how to move forward. And secondly, be proactive by annually checking levels of revenues and which states those are from. Also, inform your advisor whenever you’ve added an employee in a new state. These simple steps can help to protect your company from surprises. And Cray Kaiser, as always, is here to help you, especially as you wade the deep waters of multi-state taxation. If you’re feeling unsure about your business’s exposure across the states, please feel free to contact us. You can reach us on craykaiser.com. And we look forward to hearing from you.

Governor JB Pritzker and the Illinois Department of Revenue (IDOR) are offering temporary tax relief for individuals and businesses affected by the severe storms that swept across parts of Illinois between May and August 2026. If your ability to file and pay taxes was disrupted, you may qualify for a waiver of penalties and interest.
Here’s what you need to know.
Relief applies to areas included in Governor Pritzker’s Disaster Proclamation for Summer 2026 Storms. Currently, that includes the following counties, along with the dates of severe weather tied to each:
| County | Dates of Severe Weather |
| Alexander | July 9-11 |
| Champaign | August 9-11, August 13-16 |
| Cook | July 27, August 9-11 |

| Tazewell | August 13-16 |
| Vermilion | July 27, August 13-16 |
| Will | July 27, August 9-11 |
Any additional counties added to the disaster proclamation will also qualify, so it’s worth checking back if your county isn’t on the list yet.
If severe weather prevented you from filing or paying on time, you can request a waiver of penalties and interest on:
To request a waiver, submit a brief explanation of why the storms affected your ability to file or pay. Be sure to include:
You can send your requests in one of two ways:
Email: RE****************@******is.gov
Mail: Use the address listed on your return and write “Severe Storms – Summer 2026” in red ink at the top.
If IDOR has already assessed penalties against you, you still have options. Email RE****************@******is.gov with your name, business name, account number(s), and the affected filing periods, and they’ll work with you from there.
For the most current details, visit the Illinois Department of Revenue here.
Storm recovery brings enough to think about without worrying whether your taxes were filed and paid on time. If you were impacted and aren’t sure whether you qualify or need help putting together your request, the team at CK is here to help you sort through it.

Each year, millions of people have their identities stolen in different ways, including theft of their tax information. Taxpayer identity theft is becoming more prevalent, but there are simple steps you can take to protect yourself.
Taxpayer identity theft happens when someone steals your personal information, like your social security number and uses it to file a fake tax return in your name so they can claim your refund. This is often done early in the filing season before you have even started your return. Most people are unaware until they try to file a return and discover that IRS has already received a return under their name and their return is either rejected or the IRS asks for additional information to sort out the mix-up.
While it is impossible to eliminate identity theft, there are ways to minimize the risks. Some steps for you to consider:
Be vigilant! Requesting an IP PIN ahead of time is one of the best ways to prevent a fraudulent return from being filed. Remember, the IRS and state government will never contact you by email, telephone, text message, or social media to ask for personal, financial, or IP PIN information. Also, the IRS and state governments will not accept payments using gift cards.
We hope this information is helpful. If you’d like to discuss this information or feel you have been a victim of identity theft and would like our assistance in working with the IRS, please contact us at (630) 953-4900.

Governor J.B. Pritzker recently signed a new state budget bill into law for the state of Illinois. There are numerous changes that could impact you and your business. Some of the most notable changes include limiting the Net Operating Loss (NOL) deduction, a change in the entity level tax election (PTET), disallowance of the federal Qualified Small Business Stock gain exclusion, and a reduced sales tax holiday for roughly a week in August 2026.
If your business loses money in one year, you can normally use that loss to reduce your taxes in future years. Illinois limits how much of that loss you can use each year and is changing that limit.
What’s changing:
Bottom line: Corporations with large prior-year losses will continue to face restrictions on how quickly they can use those losses to offset current taxes, though the cap gradually loosens over time.
PTET lets partnerships pay Illinois state tax at the business level instead of passing that tax burden on to individual partners. This helps partners get around the federal limits on deducting state taxes personally. Illinois is now giving partnerships two ways to calculate this tax. For tax years ending on or after December 31, 2026, partnerships making the Illinois entity-level tax election may choose between two annual tax-base methods: the full distributive share method or the Illinois-sourced income method. The elected method is irrevocable for that taxable year. Current guidance applies this new method to partnerships and does not clearly extend to S corporations:
Bottom line: Partnerships with a mix of resident and nonresident partners should evaluate both methods before making the election, since the right choice can meaningfully change the amount of taxes paid.
Under Federal tax law (Section 1202) certain gains on the sale of qualified small business stock can be excluded from taxable income. Illinois is joining California and decoupling from this code section.
What’s changing:
To end with some good news, for the first time since 2022, Illinois is providing a reduced sales tax rate in August for back-to-school season for certain tangible goods. The Illinois sales tax holiday runs from August 7, 2026, through August 16, 2026, applies to eligible clothing items under $125 and school supplies. Taxes on those items will be 1.25% instead of the general rate. City and local taxes will still apply.
These changes affect different businesses in different ways depending on your entity type, income and whether you’re carrying forward prior losses. If you have questions about how any of these changes apply to your or your business, please contact the trusted advisors at CK. You can call us at (630) 953-4900 or fill out this form.

Beginning August 1, 2026, local sales tax rates in some Illinois counties will increase by 0.25%. Retailers and servicepersons making taxable sales in Cook, DuPage, Kane, Lake, McHenry, or Will counties must increase their local sales tax rate by 0.25%. The increase is to the Northern Illinois Transit Authority (NITA) portion of sales tax collected in these counties.
The new rate will appear on your Illinois sales/use tax Form ST-1 when your business electronically files on MyTax Illinois. You may also find your updated rate using the MyTax Illinois Tax Rate Finder. Select “August 2026” rates to look up the exact rate for your business address.
To stay compliant and avoid under-collecting sales tax, businesses in the affected counties should complete these steps before the effective date:
If a sale was made prior to August 1, 2026, and was properly taxed at the prior (lower) rate, report it on Line 8a of Form ST-1 or ST-2. Note – line 8a may only be used for sales properly subject to a different rate.
Getting ahead of this update now ensures your business collects the correct sales tax from day one. The new tax will be in effect August 1, regardless of whether your business makes the change in your system. Cray Kaiser is here to help if you have any questions about how this change affects your business or need assistance updating your systems.

Illinois businesses, take note. Effective July 1, 2026, dozens of taxing jurisdictions across the state will impose new local sales taxes or update their existing rates on general merchandise sales. Whether you operate a storefront, sell remotely, or facilitate marketplace transactions, now is the time to review your obligations and update your systems.
The following local sales taxes will be affected by the July 1, 2026, changes:
Also note: The Illinois Department of Revenue (IDOR) will issue a separate bulletin covering changes to the Municipal and County Grocery Occupation Tax, effective July 1, 2026. Food items previously grouped under the general exemption language are addressed separately in this cycle.
Locally imposed sales taxes apply to the same items of general merchandise reported on Line 4a of Forms ST-1 and ST-2 that are subject to State sales tax.
Locally imposed sales taxes do not apply to:
Make sure any cash registers and computer programs are updated to reflect the new tax rates beginning July 1, 2026. If a software vendor manages these processes, contact them immediately to begin implementing the changes.
Use the MyTax Illinois Tax Rate Finder here to verify your new combined sales tax rate (State and local sales taxes). Be sure to select rates for July 2026.
If a prior sale was subject to a sales tax rate different from the current rate, report this on Line 8a of Forms ST-1 and ST-2. Note: Line 8a is used only for sales subject to a different tax rate; no other use is permitted.
Your business address determines whether business district sales tax applies to your sales. Remote retailers and marketplace facilitators who meet the $100,000 tax remittance threshold should pay extra attention to those taxes. Refer to the MyTax Illinois Tax Rate Finder for a full list of business district addresses and applicable rates.
Avoid headaches and prepare now for this sales tax rate update. If you have questions or need assistance navigating these changes, Cray Kaiser is here to help. Contact your trusted advisors at (630) 953-4900 to ensure you’re ready for the July 1, 2026, rollout.

A recent federal court decision, Kwong v. United States, may create an opportunity for certain taxpayers to recover penalties and interest assessed during the COVID‑19 relief period. The law in this area continues to develop. The IRS is appealing the decision, so nothing has been settled yet. However, this ruling highlights potential refund and abatement opportunities related to IRS deadlines that were postponed under pandemic‑era disaster relief provisions. Affected taxpayers should review and act immediately to file a protective claim and secure any refunds if the IRS appeals fail.
During COVID‑19, the IRS gave everyone extra time to file federal taxes and make payments. The Kwong case ruled that the IRS may not have applied those extended deadlines correctly when it came to certain penalties and interest assessments. If that’s correct, some of those changes shouldn’t have been assessed in the first place. As a result, some taxpayers who paid penalties or interest during the pandemic period or continue to have outstanding assessed amounts may be eligible to claim relief.
If you (or your business) were charged any of the following between 2020 and 2023:
These penalties apply not only to individuals, but would also apply to businesses, trusts and estates. Please note that the failure-to-file penalty for partnerships and S-Corporations can be significant as the IRS charges these penalties per month per partner with a maximum of 12 months. During the period above, the amount ranged from $205 to $220 per month, per partner. That’s not a trivial amount.
A few things to keep in mind:
We are actively monitoring developments related to this case and can assist with:

As the ink dries on the One Big Beautiful Bill Act (OBBBA), many taxpayers are wondering: What does this mean for me, my business and my bottom line?
While much of the discussion focuses on federal tax changes, state tax laws are also affected. State legislators must decide whether to align to the new federal rules. It’s unknown how quickly state legislators will respond to the changes. Because of this, taxpayers could see difference in how their income, deductions and credits are treated from state to state.
Here’s a breakdown of the key areas where OBBBA could impact state taxes and what you should watch for.
The state tax deduction (SALT) cap, originally limited to $10,000 under the Tax Cuts and Jobs Act of 2017 (TCJA), has been increased under OBBBA to $40,000 for joint filers and $20,000 for certain individuals.
In response to the old cap, 36 states enacted a Pass-Through Entity Tax (PTET), where flow through entities were allowed to pay state tax on behalf of owners and deduct them as business expenses.
Now that the SALT limit has increased, some business owners may want to reconsider PTET elections. Additionally, some state PTET provisions are set to expire at the end of 2025, and it’s unclear which states will extend the PTET.
What this means for you: If you currently use or are considering a PTET election, it’s a good time to re-evaluate your strategy with your tax advisor.
Under TCJA, bonus depreciation, which allows businesses to deduct the full cost of qualifying assets, has been phasing out from 100% down to 40% in 2025, and ultimately to zero in 2027. The OBBBA reverses this trend by reinstating 100% bonus depreciation for assets acquired after January19, 2025.
However, many states do not allow this deduction. Businesses will need to continue to track state differences in depreciation rules to avoid surprises when filing state returns.
What this means for you: Be aware that even though you may get the full deduction at the federal level, your state may not conform.
Beginning in 2025, the limitation on business interest expense will be expanded to apply to EBITDA (earnings before interest, taxes, depreciation and amortization).
Because each state chooses whether to follow the federal rule (Section 163(j)), conformity varies widely. This means your allowable interest deductions may differ by state.
What this means for you: Businesses with multi-state operations should carefully review where and how these new limitations apply.
The OBBBA reinstitutes immediate expensing of R&E costs. It also allows for accelerated deductions for costs that were capitalized between 2022-2024.
Since each state handles R&E costs differently, you’ll need to identify which states plan to conform to the new rules beginning in 2025.
What this means for you: If your business invests in research or development, this change could offer significant tax savings, but only if your state follows the new federal approach.
Each state decides whether to adopt federal tax changes, ignore them or modify them. This can be overwhelming for business owners, especially those operating in multiple states.
Analyzing these differences can be complex and time-consuming, but it’s crucial to ensure accurate tax filings and avoid penalties.
Navigating federal and state tax changes under the One Big Beautiful Bil Act doesn’t have to be overwhelming. The team at Cray Kaiser can help you analyze the effect on your business. Although we usually start looking at year-end tax planning in Q4, now is the time to talk with your advisor about the impact of the bill on your state taxes. Contact Cray Kaiser and learn how these changes may impact your bottom line.

The One Big Beautiful Bill Act was signed into law on July 4th. The law significantly expands the Qualified Small Business Stock (QSBS) exclusion under Internal Revenue Code 1202 for stock acquired after July 4, 2025.
Below is a concise summary of the changes:
Stock acquired before July 4, 2025
Stock acquired on/after July 4, 2025

The Qualified Opportunity Zone (QOZ) program was originally introduced as part of the Tax Cuts and Jobs Act (TCJA) of 2017 to encourage long-term investments in economically distressed communities. The One Big Beautiful Bill Act (OBBBA), is bringing major updates to this tax incentive program, giving investors and developers new benefits and rules.
Here’s a breakdown of what’s new, why it matters and how you can prepare for what’s next.
A Qualified Opportunity Zone is a designated economically distressed area in the U.S. The goal is to encourage private investments in these zones by offering tax breaks to investors to stimulate growth and development in these areas.
Under the original rules, investors could benefit from:
However, these benefits were set to expire on December 31, 2026, which limited long term planning.
The One Big Beautiful Bill Act gives the Opportunity Zone program new life by removing the expiration date and introducing a set of enhancements designed to focus investment in the areas that need it most.
Here are the key updates:
The Program is Permanently Extended
The QOZ program is no longer set to expire in 2026. Instead, it’s been extended indefinitely, providing long-term stability for investors and developers.
New Zones Every 10 Years
Stricter Eligibility Requirements for Zone Designation
To better target areas in need:
Updated Tax Incentive
There are a few important adjustments to how tax breaks work:
New Opportunities for Rural Investors
For the first time, there’s a special focus on rural America through the creation of Qualified Rural Opportunity Funds. These funds come with extra perks, including:
Unfortunately, these exciting changes do not take effect until January 1, 2027. This means all investments prior to then will fall under the old QOZ rules. Under the old rules gains are only deferred until 2026, at which point you must report and pay tax on them. A one-year deferral isn’t much of an incentive for investing prior to 2027. Because of this lag in policy, experts anticipate a slowdown in QOZ funds as investors wait for the new rules and longer deferral periods to kick in.
The Opportunity Zone program has entered a new era. With enhanced benefits, a focus on rural areas, and long-term stability, investors may find fresh reasons to explore these communities and investments. But until the new rules take effect, investors should consider holding off on QOZ opportunities until they can take full advantage of the new benefits starting in 2027.
If you’re wondering how these changes could affect your investment strategy, our tax experts can help you evaluate your options and prepare for the new Opportunity Zone landscape. Contact us to learn how to make the most of these upcoming opportunities.
