Tax planning isn't a once-a-year event. Here's the quarter-by-quarter calendar that WELLTH uses to keep clients ahead of deadlines, optimize savings, and eliminate April surprises.

Why April Shouldn't Be Your Tax Season

For most business owners, "tax season" means January through April, a frantic scramble to gather documents, meet with the CPA, and hope for the best. But the business owners who save the most treat tax planning as a year-round discipline.

Every quarter presents unique opportunities to reduce your tax liability, optimize your structure, and make decisions that compound over time. Here's the calendar WELLTH uses with our advisory clients.

Q1: January – March (Set the Foundation)

The first quarter is about setting the stage for the entire year. This is when most of your strategic decisions should be made.

Key Actions:

  • Review last year's tax position: Before filing, analyze what worked and what didn't. Where did you overpay? What deductions did you miss?
  • File S-Corp election (if applicable): The deadline is March 15 for calendar-year businesses. If you're electing for the first time, this is your window.
  • Set your reasonable salary: If you're an S-Corp, determine your salary for the year based on current market rates and your expected revenue.
  • Fund retirement accounts: You have until your tax filing deadline to contribute to a SEP-IRA for the prior year. Plan this year's contributions now.
  • Review your entity structure: Has your business changed? New revenue streams, new partners, new states? Your entity should evolve with your business.

WELLTH Tip: This is when we conduct our comprehensive Tax Assessment for new clients. Starting in Q1 means you have the entire year to implement strategies, not just react to them.

Q2: April – June (Implement and Adjust)

The second quarter is about implementation. Your strategy is set, now execute it.

Key Actions:

  • File or extend your return: April 15 is the deadline for individual returns; March 15 for S-Corp and partnership returns. Extensions are fine, but estimated payments are still due.
  • Make Q1 estimated tax payment: Due April 15. Base this on your projected annual income, not just last year's.
  • Review Q1 financials: Are you on track with your projections? If revenue is higher or lower than expected, adjust your strategy now.
  • Maximize mid-year deductions: Equipment purchases, professional development, and business travel planned for Q2 should be documented and categorized.
  • Make Q2 estimated tax payment: Due June 15.

WELLTH Tip: We schedule our first quarterly check-in during this period. It's early enough to course-correct if your income is trending differently than projected.

Q3: July – September (Optimize and Accelerate)

The third quarter is the optimization window. You have enough data to see where the year is heading and enough time to make meaningful adjustments.

Key Actions:

  • Mid-year tax projection: Run a projection based on actual YTD income and expenses. Compare to your annual estimate. Are you on track to owe more than expected?
  • Accelerate deductions if needed: If you're trending toward a higher tax bill, consider accelerating planned expenses into Q3 (equipment, supplies, prepaid expenses).
  • Review retirement contribution strategy: Are you maximizing your Solo 401(k) or SEP-IRA? Adjust payroll contributions if needed.
  • Make Q3 estimated tax payment: Due September 15.
  • Plan year-end charitable giving: If you plan to donate, strategize now for maximum tax benefit (donor-advised funds, appreciated stock donations, etc.).

WELLTH Tip: This is the most underutilized quarter for tax planning. Most business owners are heads-down running their business. But the decisions you make in July and August can save you thousands in April.

Q4: October – December (Close Strong)

The fourth quarter is your last chance to make moves that affect this year's tax position. Every decision counts.

Key Actions:

  • Final tax projection: Run your numbers one more time. Know exactly where you stand before December 31.
  • Maximize retirement contributions: Solo 401(k) employee contributions must be made by December 31. Employer contributions can wait until the filing deadline.
  • Harvest tax losses: If you have investments with unrealized losses, consider selling before year-end to offset gains.
  • Defer income if beneficial: If you expect lower income next year, consider deferring December invoices to January.
  • Accelerate expenses: Prepay January rent, stock up on supplies, or make planned equipment purchases before December 31.
  • Make Q4 estimated tax payment: Due January 15 of the following year.
  • Review health insurance and benefits: Open enrollment decisions affect both your taxes and your wellbeing.

WELLTH Tip: We schedule our final quarterly check-in in November, early enough to implement year-end strategies but late enough to have accurate projections.

The Compound Effect of Year-Round Planning

The difference between reactive and proactive tax planning compounds over time. A business owner who saves $15,000 per year through strategic planning has an extra $150,000 over ten years: before accounting for investment returns on that savings.

That's not a tax refund. That's a retirement fund. A college fund. A business expansion fund. That's real wealth.
