If you own a profitable business in a high-tax state, you are likely losing a massive portion of your wealth to a frustrating federal tax rule. When the Tax Cuts and Jobs Act (TCJA) was passed in 2017, it introduced a strict $10,000 limit on the State and Local Tax (SALT) deduction.
For high-net-worth entrepreneurs living in states like California, New York, or New Jersey, this cap was devastating. Suddenly, hundreds of thousands of dollars in state income taxes were no longer deductible on federal returns. Business owners were effectively being taxed twice on the same money.
Here is the deal:
You do not have to accept this double taxation. Over the past few years, a brilliant, IRS-approved legislative solution has swept across the country. It is called the Pass-Through Entity (PTE) tax, and it is the single most effective tax strategy available to small and medium-sized businesses today.
As a CPA who has helped businesses implement this strategy to save millions of dollars, I can tell you that ignoring this option is a costly mistake. This comprehensive guide will break down exactly how the PTE tax works. We will explore the IRS guidelines, the mathematical benefits, and the hidden traps you must avoid to keep your business compliant.
Understanding the SALT Deduction Cap Workaround
To understand why the PTE tax is so revolutionary, we must first look at the problem it solves. Before 2018, if you paid $50,000 in state income taxes, you could deduct that entire $50,000 on your federal Schedule A as an itemized deduction. This lowered your federal taxable income significantly.
The TCJA capped that deduction at a mere $10,000. For most successful business owners, that $10,000 cap is entirely eaten up by their local property taxes. This leaves zero federal deduction for their state income taxes.
Why does this matter?
Because pass-through entities—like S-Corporations, Partnerships, and multi-member LLCs—do not pay federal income tax at the corporate level. The profits “pass through” to the owners’ personal tax returns. Therefore, the state income taxes generated by the business were being paid at the personal level, subjecting them to the harsh $10,000 SALT cap.
The Solution: IRS Notice 2020-75
State legislatures realized this federal cap was hurting their local business owners. To fix it, states began creating a legal workaround. They enacted laws allowing pass-through entities to pay the state income tax voluntarily at the entity level, rather than the personal level.
The question was: Would the IRS allow this?
In November 2020, the IRS released IRS Notice 2020-75. This notice officially blessed the strategy. The IRS clarified that state income taxes paid by a partnership or an S-Corporation are fully deductible as ordinary and necessary business expenses. Because the tax is paid by the business, it bypasses the individual $10,000 SALT cap entirely.
This ruling opened the floodgates. Today, over 36 states have enacted some form of a SALT deduction cap workaround.
What is a Pass-Through Entity (PTE) Tax?
The Pass-Through Entity (PTE) tax is an elective tax regime. It allows a qualifying business to pay state income tax on its net profits directly to the state revenue department.
When the business pays this tax, it deducts the payment on its federal tax return (Form 1120-S for S-Corps or Form 1065 for Partnerships). This reduces the total amount of federal taxable income that passes through to the owners.
But what happens at the state level?
To prevent the business owner from being taxed twice by the state, the state provides a corresponding benefit on the owner’s personal state tax return. Depending on the state, the owner receives either a dollar-for-dollar tax credit for the PTE tax paid by the business, or an income exclusion.
The net result is brilliant. Your state tax liability remains roughly the same, but your federal taxable income drops significantly, saving you thousands of dollars in federal taxes.
State Income Tax Deduction for LLCs: Eligibility Rules
Not every business can take advantage of this strategy. The rules governing the state income tax deduction for LLCs are strict, and they vary wildly depending on where your business is registered.
Generally, the following entities are eligible to make a PTE tax election:
- S-Corporations: Both state-law corporations and LLCs that have elected S-Corp taxation status.
- Partnerships: Multi-member LLCs, General Partnerships, and Limited Liability Partnerships (LLPs).
Here is the catch:
Single-member LLCs (SMLLCs) that are taxed as disregarded entities (filing a Schedule C on a personal return) are almost universally excluded from the PTE tax. Because a disregarded entity is not legally separate from its owner for tax purposes, it cannot pay an entity-level tax.
If you operate a highly profitable single-member LLC in a high-tax state, this is a massive reason to consult your CPA about electing S-Corporation status. Converting to an S-Corp unlocks your ability to use the PTE tax workaround.
How the PTE Tax Election Works
Executing this strategy requires precise timing and flawless bookkeeping. You cannot simply write a check to the state and claim the deduction. You must follow a formal election process.
Please note: This varies by state, consult your local jurisdiction. However, the general workflow follows these steps:
Step 1: Making the Election
In most states, the PTE tax is voluntary. You must actively opt-in. Some states require you to make the election early in the tax year (e.g., New York requires the election by March 15). Other states allow you to make the election when you file your final tax return.
If you miss your state’s election deadline, you are locked out of the savings for that entire tax year. There are rarely exceptions for late filings.
Step 2: Paying Estimated Taxes
Once you elect into the PTE regime, the business is now responsible for paying the state tax. This means the business must make quarterly estimated tax payments to the state.
If the business fails to make these estimated payments, the state will assess underpayment penalties and interest. Furthermore, for cash-basis taxpayers, you can only deduct the PTE tax on your federal return in the year the cash actually leaves your bank account. If you want the federal deduction for 2024, the business must pay the state tax before December 31, 2024.
Step 3: Filing the Returns
At year-end, your CPA will file a specific PTE tax return for the business. The business will issue a Schedule K-1 to the owners. This K-1 will show the reduced federal income, and it will include a specific line item showing the owner’s share of the state tax credit.
The owner then files their personal tax return, claiming the state tax credit to offset their personal state income tax liability.
Actionable Case Study: Saving $14,000 with the PTE Tax
Tax theory is helpful, but seeing the math in action proves the immense value of this strategy. Let us look at a realistic scenario involving a successful marketing agency.
The Scenario:
David owns “Apex Marketing LLC,” which is taxed as an S-Corporation. The business operates in California and generates $500,000 in net profit. David is in the 35% federal income tax bracket. His personal SALT deduction is already maxed out at $10,000 due to his property taxes.
Let us compare David’s tax burden with and without the PTE tax election. (Note: California’s PTE tax rate is 9.3%).
Option A: Without the PTE Tax Election
- Federal Taxable Income: The full $500,000 passes through to David.
- State Tax Liability: David pays 9.3% on $500,000 = $46,500 out of his personal bank account.
- Federal Deduction: Because David’s $10,000 SALT cap is already used by property taxes, he gets a $0 federal deduction for this $46,500 state tax payment.
- Federal Tax Paid on the State Tax Money: David pays 35% federal tax on that $46,500, which equals $16,275.
Option B: With the PTE Tax Election
- The Election: Apex Marketing LLC elects into the CA PTE tax and pays the $46,500 directly to the state before December 31.
- Federal Deduction: The LLC deducts the $46,500 as a business expense.
- New Federal Taxable Income: The income passing through to David drops from $500,000 to $453,500.
- State Tax Credit: David receives a non-refundable credit on his personal CA return to offset his personal state tax liability.
The Financial Outcome:
By making the PTE election, David reduced his federal taxable income by 46,500.Athis3516,275 in federal income taxes. He paid the exact same amount to the state of California, but he stopped the IRS from taxing that money.
The QBI Deduction Interaction: A Crucial CPA Insight
If you are a business owner, you are likely familiar with the Qualified Business Income (QBI) deduction under Section 199A. This allows eligible business owners to deduct up to 20% of their net business income on their federal return.
When you implement the PTE tax strategy, it interacts directly with your QBI deduction. You must understand this math to ensure the strategy is actually profitable.
Here is the deal:
Because the PTE tax is deducted as a business expense, it lowers your net business income. Because your net business income is lower, your 20% QBI deduction will also be slightly lower.
Using the previous case study, David’s net income dropped by $46,500. This means his QBI deduction will decrease by $9,300 (20% of $46,500). At a 35% tax rate, losing that QBI deduction costs him $3,255.
However, the federal tax savings from the PTE deduction (16,275)faroutweighthecostofthereducedQBIdeduction(3,255). David still walks away with a net tax savings of over $13,000. Your CPA must run this specific calculation to ensure the PTE election yields a net positive result for your specific tax bracket.
Multi-State Operations: The Complexity Multiplier
The PTE tax is relatively straightforward if your business operates in a single state. But if you have a remote workforce or sell products across state lines, the complexity multiplies exponentially.
If your business has physical nexus in multiple states, you may be required to file PTE tax returns in several jurisdictions. This requires a deep understanding of state apportionment rules.
Why does this matter?
Because not all states play nicely together. If your business pays a PTE tax in State A, but you live in State B, State B might not recognize the tax credit. This is known as the “resident credit issue.”
For example, if you live in a state that does not have a PTE tax regime, and your business pays a PTE tax to a neighboring state, your home state might refuse to give you a credit for taxes paid to another state at the entity level. This could result in double taxation at the state level, completely wiping out your federal tax savings.
This varies by state, consult your local jurisdiction. Never make a multi-state PTE election without a comprehensive tax projection from a licensed CPA.
Common Pitfalls to Avoid
The SALT deduction cap workaround is powerful, but it is riddled with legislative landmines. Avoid these common mistakes to protect your business.
1. Missing the Election Deadline
As mentioned earlier, state deadlines are unforgiving. Some states require the election by March 15, others by the original due date of the return, and some require it to be made via a specific online portal. If you miss the deadline, you cannot retroactively elect in. You lose the deduction for the entire year.
2. Failing to Pay Before December 31
Most small businesses are cash-basis taxpayers. This means you can only deduct an expense in the year the cash actually leaves your bank account. If you want to lower your 2024 federal tax bill, the business must physically pay the PTE tax to the state before December 31, 2024. If you wait until March 2025 to pay the 2024 state tax, you cannot claim the federal deduction until you file your 2025 tax return.
3. Non-Resident Partner Complications
If your partnership has owners who live in different states, the PTE election can cause friction. In some states, the election is binding on all partners. If the election benefits the partners living in high-tax states but hurts the partners living in low-tax states (due to resident credit issues), you could face a partnership dispute. Always review your operating agreement and model the tax impact for every individual partner before making the election.
Pro-Tips for Business Owners and CPAs
To maximize the benefits of IRS Notice 2020-75, you must treat the PTE tax as a year-round planning tool, not a year-end surprise.
- Update Your Operating Agreement: If you are a partnership or multi-member LLC, amend your operating agreement to explicitly state who has the authority to make the PTE election and how the cash distributions will be handled to cover the tax payments.
- Adjust Personal Estimated Payments: If the business is now paying your state income taxes, you must stop making personal estimated state tax payments. If you continue to pay personally, you will overpay the state massively and give the government an interest-free loan.
- Monitor Legislative Changes: The federal $10,000 SALT cap is currently scheduled to expire at the end of 2025. If Congress allows it to expire, the PTE tax strategy may become obsolete. Stay in close contact with your CPA regarding the future of this legislation.
Conclusion
The $10,000 SALT cap was designed to increase federal tax revenue at the expense of high-income earners in high-tax states. However, the Pass-Through Entity (PTE) tax provides a fully legal, IRS-approved pathway to reclaim your wealth.
By understanding how the SALT deduction cap workaround functions, you can shift the burden of state income taxes from your personal return to your business. This state income tax deduction for LLCs and S-Corps drastically lowers your federal taxable income, saving you thousands of dollars every single year.
Remember that the PTE tax election requires strict adherence to state-specific deadlines, careful management of estimated payments, and a deep understanding of how it impacts your QBI deduction. Because the rules are highly localized and constantly evolving, this is not a DIY tax strategy.
Do not leave money on the table. Consult with a licensed CPA today to run a custom tax projection and determine if the PTE tax is the right move for your growing business.
Frequently Asked Questions (FAQ)
1. What is the Pass-Through Entity (PTE) tax?
The PTE tax is an elective state-level tax that allows pass-through businesses (like S-Corps and Partnerships) to pay state income tax on their profits directly. This allows the business to deduct the tax as a business expense on its federal return, bypassing the $10,000 individual SALT deduction cap.
2. Does IRS Notice 2020-75 make the PTE tax legal?
Yes. In November 2020, the IRS issued Notice 2020-75, which officially clarified that state income taxes paid by a pass-through entity are fully deductible as ordinary and necessary business expenses, and are not subject to the individual $10,000 SALT cap.
3. Can a Single-Member LLC use the PTE tax strategy?
Generally, no. Single-member LLCs that are taxed as disregarded entities (filing Schedule C) cannot pay an entity-level tax. To utilize the PTE tax workaround, a single-member LLC usually must elect to be taxed as an S-Corporation.
4. Do I still get the QBI deduction if I make the PTE election?
Yes, but it will be slightly reduced. Because the PTE tax is deducted as a business expense, it lowers your net business income. Since your Qualified Business Income (QBI) is lower, your 20% QBI deduction will also decrease. However, the federal tax savings from the PTE deduction usually far outweigh the loss in QBI.
5. When is the deadline to make a PTE tax election?
This varies by state, consult your local jurisdiction. Some states require the election to be made by March 15 of the current tax year, while others allow you to make the election when you file the final business tax return. Missing the deadline usually locks you out of the benefit for that year.
6. Do I have to pay the PTE tax before December 31?
If your business is a cash-basis taxpayer, yes. To claim the federal tax deduction for a specific tax year, the cash must actually leave the business bank account and be paid to the state before December 31 of that year.
7. What happens if the federal SALT cap expires in 2025?
The $10,000 SALT deduction cap introduced by the TCJA is currently scheduled to sunset (expire) at the end of 2025. If Congress does not extend the cap, individuals will once again be able to fully deduct state taxes on their personal returns, which may render the PTE tax workaround unnecessary in the future.
