The MARRIAGE CHECKLIST Part IV: Understanding Your New Tax Situation
[Part 4 of a 6-part series on exactly how my wife and I are organizing and planning our financial future together as newlyweds.]
Most people do their taxes. Very few actually understand them—and that’s where real money can be lost.
When Mariana and I got married, we knew our tax picture was going to change. But instead of guessing, we used the same resources our clients have access to:
✅ Holistiplan – Baird's tax analysis software that scans your return and highlights hidden planning opportunities
✅ Eric Wikstrom, our Baird Regional Tax Strategist, who ran multiple scenarios tailored to our income, goals, and Public Service Loan Forgiveness (PSLF) situation
We treat tax returns like financial blueprints—not just compliance documents.
🔍 Here is exactly what we did:
• We each uploaded our 2024 returns into Holistiplan to establish a baseline
• Eric modeled several 2025 scenarios: filing separately, filing jointly, and how each would impact PSLF payments
• We reviewed our new marginal and average tax rates and saw what we’d likely owe under each scenario
🧠 What we learned:
1️⃣ Filing separately would’ve created unnecessary complexity with minimal tax or PSLF benefit
2️⃣ Filing jointly likely lowers our bill—and gives us a clean, streamlined approach going forward
3️⃣ I’ll be switching from a Roth 401(k) to a Traditional 401(k) to take advantage of the deduction and create some "tax bucket diversification."
4️⃣ We’ll continue our annual backdoor Roth IRA contributions
🌟 Bonus: At Baird, I can make "after-tax 401(k) contributions" (or a “mega backdoor Roth”)—a powerful move if you’re already maxing your other accounts. Ask your employer if this is an option.
🧩 Why this matters for you:
Reviewing your return is like a doctor reviewing your bloodwork—you need the full picture to give great advice. A few overlooked numbers can quietly impact your:
✅ 401(k) strategy (Roth vs Traditional)
✅ Eligibility for Roth or backdoor Roth contributions
✅ Student loan repayment plans (especially under IDR)
✅ Whether to itemize vs. take the standard deduction
✅ Tax efficiency of your investments (e.g. muni bonds vs taxable, avoiding unnecessary capital gain distributions)
✅ Realization of whether you’re using all available deductions
📌 What you should know—or ask your advisor/accountant:
✔ Your marginal and average tax rates
✔ Your MAGI and AGI
✔ Whether your filing status affects student loan repayment or Roth eligibility
✔ Whether to itemize or take the standard deduction
✔ What tax planning opportunities you’re missing by not reviewing your return strategically
