Vesting Traps, Q2 Estimates, and What a Choppy Market Actually Changes
June 1, 2026
Markets have been noisy this year. Estimated payments are coming due. And a lot of people are about to make a decision on autopilot that deserves about ten minutes of real thought.
Here is what is worth your attention right now, whether you are sitting on equity compensation or running a business.
Dates to Know
June 15: Q2 estimated tax payment due. If you are self-employed, own a business, or have significant investment or equity income, your second quarter payment is due. Before you send it, make sure the number reflects where your year is actually headed, not just what you paid last year.
Through June: the mid-year S-corp salary review window. June is the sweet spot for reviewing reasonable compensation. Adjustments made now can still be implemented before year-end. Waiting until December leaves very little room to maneuver.
September 15: extended business return deadline. If your partnership or S-corp filed an extension back in March, this is your date. That is closer than it sounds. If you have not started gathering business documents, now is the time to get moving.
What the Market Is Doing, and What It Means
After a strong 2025, markets have been choppier this year. The conflict in the Middle East has been the dominant story, with the situation involving Iran disrupting global oil supply and pushing Brent crude as high as $140 per barrel at points this spring. Prices have since pulled back to around $92 on ceasefire optimism, but headline-driven volatility remains elevated. Tariffs and policy uncertainty have added to the turbulence throughout.
The good news is that corporate earnings have held up better than expected, with S&P 500 earnings growth tracking nearly 28% year over year through Q1.
The honest take: short-term market noise rarely changes what you should be doing with your financial plan. What it can do is create planning opportunities worth paying attention to.
If You Have Equity Compensation
The tax trap hiding in your vesting schedule
This is one of the most common and costly mistakes I see, and market volatility makes it more urgent.
The withholding problem. When RSUs vest, most companies automatically withhold 22% for federal taxes. For professionals in higher brackets, that is often not enough. The gap between what was withheld and what you actually owe tends to show up as a surprise bill every April. If that happened to you this year, now is the time to fix it before the next vesting event.
Why market swings matter here. Volatility directly affects the value of your shares at the moment they vest, which changes your tax bill in ways that are hard to predict without a plan. A vesting event during a dip means less income recognized. A vesting event during a rally can push you into a higher bracket than expected. Neither outcome should catch you off guard.
On concentrated positions. If a significant portion of your net worth sits in a single company's stock, the tax planning around any future sale gets complex fast. Understanding the tax implications of that position now, before you are forced to act, belongs on the agenda. That is a conversation I can help frame even if the investment decision itself belongs with a financial advisor.
Worth knowing. The IPO market is active this summer. If you hold pre-IPO equity or options at a company approaching a public offering, the 90 days surrounding a lockup expiration are some of the most consequential from a tax standpoint. Timing and sequencing that sale against your other income can make a real difference in what you keep. If that is your situation, it deserves a dedicated conversation before the window opens.
If You Own a Business
Your Q2 payment deserves a real look this year
Most business owners set their estimated payments once and leave them alone. That works in stable years. This is not a stable year.
If your revenue is up, your deductions have changed, or you have made any structural moves in 2026, the number you paid in April may be meaningfully off in either direction. Underpaying creates a penalty situation next April. Overpaying means you gave the IRS an interest-free loan for months.
The bigger opportunity right now. The One Big Beautiful Bill Act restored 100% bonus depreciation for equipment placed in service after January 2025. If you have been considering a major purchase for your business, the tax case for doing it before year-end is strong. That changes the math on your full-year projections and your estimated payments at the same time.
June is also the right time for S-corp owners to review reasonable compensation. The window to make changes that matter for 2026 is open now, and it closes faster than most people expect.
A Few Other Things Worth Knowing
The QBI deduction is now permanent. The OBBBA made the 20% qualified business income deduction permanent for pass-through owners. If you have a pass-through business of any kind, this is one of the most valuable deductions in the tax code and it is not going away. Make sure your planning is built around it.
529 plans got more flexible. The OBBBA broadened qualified expenses for 529 accounts, giving families more ways to use the funds without penalty. If you have a 529 and have been unsure whether your planned expenses qualify, the answer may have changed in your favor.
Withholding mismatches are more common than you think. Several OBBBA changes that began in 2025 carry into 2026, and many people have a gap between what their paycheck withheld and what the law now allows. If your tax situation changed this year, a quick review now prevents a larger surprise later.
Where This Leaves You
None of this requires a dramatic move. It requires about ten minutes of looking at your actual numbers instead of last year's numbers, and knowing which of these apply to you.
