Ending a business partnership is rarely a simple transaction. It’s often an emotional, professional, and financial turning point. For many women entrepreneurs, this kind of transition marks both the closing of one chapter and the powerful beginning of another.

But while the decision to leave a partnership might feel freeing, the aftermath (especially when it comes to taxes) can be more complicated than expected. Lingering obligations, overlooked forms, and shifting income can create a perfect storm of confusion, penalties, and missed opportunities.

As a 30-year-old woman business owner, you’re likely stepping into new territory on your own terms. And while you’re focused on building what’s next, the last thing you need is the IRS tapping on your shoulder about what’s behind you.

That’s why we’re here. At Insogna CPA, a leading CPA firm in Austin, Texas, we specialize in guiding ambitious women entrepreneurs through business transitions with clarity, strategy, and care. Here are five common tax mistakes women make after leaving a partnership and how you can avoid them with confidence.

1. Not Securing a Final Profit & Loss Statement Before You Exit

Before you part ways with your former business, make it a priority to request a copy of the final Profit & Loss (P&L) statement and balance sheet. This document is more than just a formality. It’s your record of how the business performed and what you’re personally accountable for when filing your taxes.

Why it matters:
 Your portion of the business’s income or losses must be reported accurately on your tax return. If you don’t have the final P&L, you may rely on incomplete or outdated financials, leading to misreporting income, missed deductions, or incorrect tax payments.

Pro Tip:
 Get all your financial documents—final P&L, balance sheet, capital account details—before the exit becomes final. A certified accountant near you can help you review and interpret these numbers properly.

2. Overlooking the Impact of Missed K-1s

A Schedule K-1 is issued to each partner in a partnership and reflects their share of the business’s income, deductions, and credits. Even after you’ve left the business, if you were a partner during the year, you are legally required to report the income (or losses) shown on your final K-1.

Why it matters:
 If you don’t receive this document or forget to report it, the IRS sees this as underreporting income. This can lead to penalties, interest, or even an audit.

The risk grows if:

  • You’ve moved or changed contact details and the K-1 doesn’t reach you.

  • Your former partners didn’t follow through with tax prep on their end.

  • You’re doing your own taxes or relying on a generic tax preparer near you instead of a real estate-savvy tax professional or enrolled agent.

Pro Tip:
 Stay in contact with your former partners through tax season, and request updates on when the K-1 will be issued. Work with a CPA in Austin, Texas who ensures it’s reported correctly, even if you’ve already stepped away from the business.

3. Paying Estimated Taxes Without Updated Income Figures

Let’s be honest. Your income picture likely changed the moment you stepped away from your partnership. But if you kept paying quarterly estimated taxes based on last year’s higher earnings, you might be overpaying and draining your cash flow unnecessarily.

On the flip side:
 If your new income streams are higher than expected and you’re still using outdated estimates, you may be underpaying and that can trigger IRS penalties.

How to fix it:
 A tax advisor in Austin will recalculate your quarterly tax payments using updated projections based on your new income sources whether that’s freelance work, consulting, product sales, or a new business entity.

What we often see:
 Many self-employed women leaving a partnership rely on blanket estimates or plug-and-play online tools like the 1099 tax calculator or QuickBooks Self-Employed which can miss the mark without tailored inputs.

4. Underestimating Penalties, Deadlines, and Paperwork

After a big transition, it’s easy to feel like things are simpler. No more shared bookkeeping. No more partner disputes. But that illusion of simplicity can lead to real problems when it comes to taxes.

Common oversights include:

  • Missing deadlines for 1099-NEC or W9 tax forms

  • Not filing FBAR (Report of Foreign Bank and Financial Accounts) if applicable

  • Forgetting to update your entity structure or employer identification number (EIN)

  • Missing local franchise or state filing obligations

What this leads to:
 Penalties. Interest. Stress. And sometimes an audit.

A better approach:
 Partner with a certified public accountant near you who doesn’t just file paperwork but tracks every deadline, cross-checks every form, and helps you feel two steps ahead instead of two steps behind.

5. Not Creating a Plan for Personal Liability

This is the one we wish more women knew about. Just because you left the partnership doesn’t mean the IRS sees your name as cleared from obligations. If you were a signer on bank accounts, responsible for payroll, or had guaranteed loans, you may still carry personal liability.

This is especially true if:

  • There are unpaid payroll taxes

  • The partnership didn’t formally dissolve with proper documentation

  • There are unresolved business debts

What can go wrong:
 You get a notice a year later. Or worse, you’re dragged into a legal or financial issue that’s no longer your responsibility… but still your name is attached to it.

How we help:
 As a trusted CPA firm in Austin, Texas, we walk you through a post-exit financial checklist. We review partnership agreements, help remove you from financial accounts, and document your disassociation properly. This isn’t just smart. It’s self-protection.

Moving Forward with Confidence and Clarity

Leaving a partnership isn’t just closing a chapter. It’s rewriting the next one entirely. It’s a bold move. A statement. A moment when you reclaim your time, your vision, and your voice as a woman business owner.
