Quick Answers: What Are the OBBBA’s Excess Business Loss Limitations?
- The OBBBA made the Excess Business Loss limitation permanent (previously set to expire in 2028).
- For 2025, the IRS limits your deductible loss to 313K if single, 626K if married.
- Any losses beyond the limit may be carried forward to offset future taxable income.
- The rule mostly affects individual owners of pass-through entities (partners, S-corp shareholders, sole proprietors) — not the businesses themselves.
For a lot of Milwaukee business owners, a loss on the books can actually be a lifeline. Especially if you’ve got a side hustle or a brand-new venture.
It can wipe out other income (think wages, dividends, even your spouse’s paycheck) and turn into a helpful tax refund, up to a certain amount.
The Excess Business Loss limitation puts a hard cap on how much of that loss you can apply in a given year. And Congress made that cap permanent.
Which means your losses may not stretch as far as you expect. Yes, this is a tax rule, but it has direct implications for your cash flow and overall business strategy, too.
So, let’s take a closer look at what the OBBBA’s Excess Business Loss limitations really mean for your business and how you should strategize for them.
How Do Excess Business Losses Work?
Your ‘excess loss’ is basically your business deductions minus your business income, after factoring in the yearly IRS limit: 313K for single filers and 626K for joint filers.
If your losses go over the limit, you can’t use the extra this year. But you don’t lose it. It gets saved and becomes a carried-forward loss that can be applied in future years.
Here’s an example. Imagine you run a graphic design business. Your business makes 150K in income, but you spend 500K on expenses. That leaves you with a 350K loss. On top of that, you also earn 80K from part-time work.
Remember, the IRS limit for a single filer is 313K. Since your loss is 350K, that means 37K is “excess” and can’t be used this year. The remaining 313K of your business loss can be applied against your income.
What this means, in practice, is that your 80K of part-time income is completely offset, leaving you with no taxable income for the year. The rest of that allowable loss (233K), is carried forward and can be applied to reduce your tax liability in future years.
The real benefit here is cash flow. You don’t have to pay taxes on your part-time income this year, and you’ll also have a sizeable tax break to apply in the future.
Originally, these rules were supposed to end in 2028, but the OBBBA has made them permanent.
Why Does This Matter For My Business?
There are 3 big implications of the OBBBA’s Excess Business Loss limitations for your Milwaukee business:
- Your cash flow: Losses can no longer fully wipe out other income. That means bigger tax bills in tough years. If you’re planning big investments (say, new equipment with heavy depreciation), know that some of those deductions might be capped.
- You have a safety net: You don’t “lose” what goes over the yearly IRS limit. It becomes stored-up tax relief for future years. Which is why having precise and up-to-date financial records is critical. It allows you to see the true impact on your cash flow and plan accordingly.
- Year-round planning is critical: The permanence of the rule means it needs to be part of your ongoing, year-round business strategy. This is where working with a bookkeeper or business advisor can help. We can provide the accurate, real-time financial data you need to make informed decisions about timing income and expenses.
FAQs: Excess Business Loss Limitations
“How much of my business loss can I deduct in 2025?”
For 2025, you can deduct up to 313K of losses if you file single and 626K if you file jointly. Anything above that can’t be used this year, but it rolls forward as a tax benefit for the future.
“Can I use business losses to reduce my other income, like wages or investments?”
Yes, but only up to the IRS limit. Losses can offset things like your salary, dividends, or even your spouse’s paycheck. But only within the cap. Anything extra gets carried forward.
“What happens to losses I can’t deduct this year? Do I lose them?”
No, you don’t lose them. They turn into what’s called a Net Operating Loss (NOL) and carry forward to future years. However, NOLs can only offset up to 80 percent of taxable income in those years.
“Do these rules apply to corporations too?”
No. C corporations aren’t affected. The rules only apply to individuals, like sole proprietors, S-corp shareholders, and partners in partnerships. And only to your share of the loss – not the whole business’s numbers.
“What should I do if I know I’m going to have a big loss year?”
Think about timing. You may want to spread out expenses or move income around so you don’t “waste” deductions that get capped.
This is where proactive financial planning is key. We can work together to analyze your financial position and help you prepare for a conversation with your tax advisor. They can then develop a strategy to maximize the benefit of your losses and minimize surprises.
“Should I change how I pay myself to avoid the business loss limit?”
That’s a specific tax strategy that you need to discuss with your tax professional. Changing how you pay yourself can have a lot of tax implications that go beyond this rule. So, make sure to keep accurate records of your compensation so that your tax pro has the numbers to work with.
“How do I know if I’m close to the Excess Business Loss limit?”
That’s a key question we can address together. By regularly reviewing your profit and loss statements, we can project your annual business income and deductions. This gives you an early warning if you’re heading toward a potential excess loss situation, allowing you to plan ahead.
