Material participation: Why it matters for LLP and LLC owners
LLC and LLP owners: Can you deduct your business losses this year? The answer may depend on whether your activity is considered passive according to the IRS’s passive activity loss rules.
Under these rules, you generally can use passive losses only to offset income from other passive activities. If you meet certain “material participation” criteria, however, you may be able to offset LLC or LLP losses against nonpassive income, such as wages, interest, dividends and capital gains — but the rules can be complex, especially for limited partners.
Contact us for guidance on tracking your participation hours, applying the material participation test and maximizing business loss deductions. ... See MoreSee Less
Your post-tax-filing checklist
After you’ve filed your 2025 tax return, what’s next? Here are a few to-dos: 1) Check your refund status by going to irs.gov and either logging into your IRS account or using the refund tracker. 2) If you forgot to report some deductible 2025 expenses (or anything else), file an amended tax return to claim those deductions and potentially increase your refund. 3) Store your return and supporting documents in a secure place where you’ll easily be able to find them if needed. 4) Turn your tax focus to 2026 planning. We can help project your income, deductions and credits for the year and propose strategies you can implement in the coming months to reduce your taxes. Contact us to get started. ... See MoreSee Less
