Is Your CPA Planning Your Taxes or Just Filing Them? (There's a $20K Difference)

The Filing CPA vs. the Planning CPA

To be clear: filing CPAs are not bad CPAs. Filing a return accurately and on time is a legitimate, valuable service. The problem is that most business owners assume their CPA is doing more than filing—they assume they're being advised, protected, and guided toward lower taxes. Most of the time, that assumption is wrong.

The Filing CPA

• Contacts you at tax time (January through April)
• Collects your documents and files an accurate return
• Takes the deductions that are obvious from your records
• May suggest a few minor adjustments on the way out the door
• Bills you a flat fee or hourly rate for compliance work

The Planning CPA / Tax Strategist

• Meets with you quarterly (or more) throughout the year
• Reviews your income projections and identifies tax-saving opportunities before year-end
• Discusses entity structure, retirement contributions, equipment timing, and payroll strategy
• Makes specific, actionable recommendations with dollar estimates attached
• Coordinates with your bookkeeper to ensure strategies are properly documented
• Bills on a retainer model because the relationship is ongoing, not seasonal

5 Warning Signs Your CPA Is Just Filing

1. You Only Hear From Them Between January and April

If your CPA's only outreach is a request for documents in January and a tax return in March, that's a filing relationship. A planning relationship includes mid-year check-ins, Q4 strategy calls, and year-round availability. If you can't remember the last time your CPA called you proactively to discuss something, that's a red flag.

2. They've Never Discussed Your Entity Structure

If you're operating as a sole proprietor or single-member LLC earning over $60,000 in net income and your CPA has never raised the subject of an S-Corp election, you're likely overpaying self-employment tax by $5,000 to $15,000 per year. This is one of the most common and most expensive gaps in tax planning. See our guide on LLC vs. S-Corp for contractors for the full analysis.

3. They've Never Recommended a Retirement Plan

A SEP IRA can reduce your taxable income by up to $70,000 per year. A Solo 401(k) can do even more with catch-up contributions. A defined benefit plan for a high-income professional over 40 can create a deduction of $100,000 to $250,000 or more per year. If your CPA has never brought up any of these options, there's a very expensive gap in your planning.

4. Equipment Purchases Are Never Discussed in Advance

If you buy a $150,000 piece of equipment in January and your CPA finds out in February of the following year, you've missed a full year of planning around that purchase. A planning CPA would discuss whether to buy this year or next, whether to use Section 179 or bonus depreciation, and how to time it relative to your projected income.

5. You're Always Surprised by Your Tax Bill

If you open that tax return every year with anxiety because you genuinely don't know what the number will be, that's a symptom of reactive tax management. A proactive planning relationship means you know your approximate tax liability in Q3—and you've already taken action to reduce it before December 31. Surprise tax bills are a sign that nobody is steering the ship.

What Proactive Tax Planning Actually Looks Like

Proactive tax planning is not a one-time conversation. It's an ongoing process tied to your business's financial calendar. Here's what a real planning engagement looks like across the year:

• Q1 (January–March): Review prior year return, identify missed opportunities, assess entity structure, set up new retirement accounts if needed
• Q2 (April–June): Mid-year income projection, estimated tax review, retirement contribution strategy, S-Corp payroll check-in
• Q3 (July–September): Equipment purchase planning and timing, income acceleration or deferral strategies, year-end projection
• Q4 (October–December): Final year-end moves, maximize retirement contributions, accelerate deductions, defer income if appropriate, finalize equipment purchases

The Real Cost of the Gap

Let's put real numbers on what filing-only relationships typically miss. Here's a sample client: a general contractor operating as a single-member LLC, net income $280,000, no retirement plan, no S-Corp election, no home office deduction:

That's over $36,000 per year in missed savings—from strategies that are completely legitimate, well-documented, and available to anyone who knows to use them. Multiply that by five years and you're looking at $180,000 in taxes paid unnecessarily. All because nobody was doing the planning. Our complete guide to proactive tax planning walks through each of these strategies in detail.

Questions to Ask Your CPA Right Now

If you're not sure whether your CPA is planning or just filing, ask these questions in your next meeting. The answers will tell you everything you need to know:

1. "Should I be taxed as an S-Corp?" If they can't give you a clear answer with numbers, that's a gap.
2. "How much should I contribute to a retirement plan this year?" A planning CPA will have a specific recommendation based on your income projection.
3. "What should I do before December 31 to lower my tax bill?" A filing CPA won't have an answer. A planning CPA will have a list.
4. "What did we do last year to reduce my taxes proactively?" If the answer is essentially nothing, you're in a filing relationship.
5. "Can we meet in Q3 to review my year-end position?" If they say they don't typically do that, that's your answer.

What to Do If You're in the Wrong Situation

If you've recognized that your current CPA is a filer rather than a planner, you have a few options:

• Have a direct conversation with your CPA: Ask if they offer proactive planning services. Many CPAs are happy to expand the relationship if you ask—but they won't offer if you don't ask.
• Find a new CPA or tax strategist: Look for someone who specifically advertises tax planning (not just tax preparation), works with businesses at your income level, and offers quarterly meetings as a standard part of the engagement.
• Add a fractional CFO to your team: A fractional CFO can fill the planning gap without replacing your existing CPA. They work alongside your CPA to implement strategies your CPA identifies—or identifies strategies your CPA has missed.
• Get a second opinion: Our free tax savings analysis is designed exactly for this situation. We review your last two tax returns and identify the specific strategies you've been missing, with dollar estimates attached.

The good news: it's never too late to start planning. Even if you're reading this in the middle of tax season, there are strategies available for the current year that can still save you money. The strategies that work best are the ones implemented before December 31—so the sooner you start, the more you save.
