Most CPAs react to vesting events. Here’s how to get ahead of them and make sure your advisor and your tax preparer are working from the same plan.
The Problem With Reactive Tax Planning
Most CPAs are excellent at what they’re hired to do: prepare an accurate tax return based on what happened during the year. The problem is that by the time the return is being prepared, the year is over. The vesting events have already occurred. The income has already been recognized. The withholding gap has already created a balance due. The window to do anything about it has closed.
This isn’t a criticism of CPAs. It’s a structural issue. Most clients don’t bring their CPA into the conversation until tax season. By then, the planning opportunities that existed earlier in the year are gone — and the CPA’s job shifts from planning to documentation.
For tech executives with significant RSU income, this gap between what could have been planned and what actually gets filed is where real money gets left on the table.
Why RSU Vesting Creates a Coordination Problem
RSU income sits at the intersection of compensation, investment management, and tax planning in a way that most single-advisor relationships aren’t built to handle.
The Three Parties Who Need to Be Aligned
- Your employer’s payroll and equity administration — controls the withholding rate at vest and the timing of share delivery
- Your financial advisor — manages the investment portfolio and the equity compensation picture
- Your CPA — prepares the tax return and should be advising on the income impact
In most situations, these three parties operate independently. The payroll system withholds at the default rate. The financial advisor manages the shares after they land. The CPA sees the 1099 in February and files accordingly. Nobody is sitting in the middle making sure the decisions made at each step are coordinated with each other.
The result is a tax outcome that nobody deliberately designed — it’s just whatever happened by default.
What Coordination Actually Looks Like
Step 1 — Map the Vesting Schedule at the Start of the Year
The vesting schedule is known in advance. Every grant has a date, a share count, and a projected value that can be estimated based on current stock price. That information is enough to build a meaningful projection of the tax impact before the first vest of the year occurs.
At the start of each year:
- Pull the full vesting schedule for all outstanding grants
- Estimate the income impact of each vest at current stock price
- Add that projected income to the base salary, bonus, and other expected income sources
- Build a full-year income projection that captures the total tax picture
This projection becomes the foundation for every planning decision that follows.
Step 2 — Share the Projection With Your CPA Before Q1 Ends
Most CPAs are finishing the prior year’s returns in the first quarter. That’s also when they have capacity to think about the current year. Bringing the vesting schedule and income projection to your CPA in January or February — before anything has vested — creates the planning window that reactive clients never have.
What to bring to that conversation:
- The projected vesting schedule with estimated income per event
- Last year’s return as a baseline for bracket and deduction context
- Any known changes for the current year — job change, bonus structure, business income, asset sales
- Questions about withholding adequacy and estimated payment requirements
Step 3 — Address the Withholding Gap
The default federal supplemental withholding rate is 22%. For most tech executives, the actual marginal rate is 32% or 37%. That gap needs to be covered somewhere — either through adjusted withholding at the source or through estimated tax payments made during the year.
Options to discuss with your CPA:
- Adjust W-4 withholding — increase the additional withholding amount on the W-4 to cover the projected gap across all vesting events
- Request higher supplemental withholding — some employers allow a higher withholding election specifically for equity compensation
- Make quarterly estimated payments — calculate the gap per vest and cover it through the quarterly estimated payment schedule
- Combine approaches — use adjusted withholding for predictable gaps and estimated payments for variable or large events
The goal is to arrive at December 31 with a tax liability that’s been covered throughout the year — not a balance due that surfaces in April.
Step 4 — Identify Offsets Before Each Vest
With the vesting schedule mapped and the income projection in place, the next conversation is about what can reduce the taxable income in the same year.
Potential offsets to evaluate:
- Realized investment losses — harvested losses in the taxable portfolio that offset ordinary income or capital gains
- Charitable contributions — donor-advised fund contributions or appreciated stock donations that generate deductions in the vest year
- Business deductions — for clients with business income, accelerating deductible expenses into the vest year
- Retirement contributions — maximizing pre-tax retirement contributions to reduce taxable income
- Deferred compensation elections — for clients with access to a nonqualified deferred compensation plan, deferring a portion of income into future years
Not all of these will apply in every situation. The point is that the conversation about offsets needs to happen before the vest — not after.
Step 5 — Loop in the Financial Advisor on Sell Decisions
The tax planning around RSUs doesn’t end at vest. What happens to the shares after they land — hold, sell immediately, sell over time — has its own tax implications that need to be coordinated with the broader portfolio strategy.
What the financial advisor and CPA should be discussing together:
- Whether selling shares at vest makes sense given the current tax picture
- How the post-vest shares interact with the existing portfolio concentration
- Whether any planned sales should happen before or after year-end based on the income picture
- How the cost basis on shares held will affect future sales
This is the conversation that almost never happens unless someone deliberately creates the space for it.
Building the Ongoing Coordination Habit
One conversation at the start of the year isn’t enough. The vesting schedule changes. Stock prices move. Income projections shift. The coordination needs to happen on a cadence that keeps everyone current.
A Simple Coordination Calendar
January — February
- Share updated vesting schedule and income projection with CPA
- Review prior year return for carryforwards and planning context
- Confirm withholding and estimated payment strategy for the year
Before each major vest
- Confirm withholding is adequate for the specific event
- Identify any offsets available in the current quarter
- Discuss sell or hold decision with financial advisor in context of portfolio and tax picture
Mid-year — July
- Run updated full-year projection with actuals through June
- Adjust estimated payments if income is tracking differently than projected
- Review portfolio for tax-loss harvesting opportunities
Q4 — October through December
- Final year-end tax projection with remaining vests accounted for
- Execute any remaining deduction or offset strategies before December 31
- Confirm all estimated payments are on schedule
- Prepare for the filing season conversation with CPA
What to Do If Your CPA Isn’t Having This Conversation
Not every CPA is set up for proactive planning. Some practices are built around filing volume — they’re excellent at accuracy and compliance, but the relationship doesn’t naturally include mid-year strategy conversations.
If that’s the situation you’re in, there are a few options:
- Ask directly — request a planning meeting in January or February, separate from the filing process, specifically to review the vesting schedule and income projection for the year
- Bring the projection yourself — do the work of mapping the vesting schedule and income estimate, and bring it to the CPA as a starting point for the conversation
- Involve the financial advisor — if the financial advisor is tracking the equity compensation picture, they can serve as the bridge between the investment decisions and the tax implications, and bring the CPA into the loop at the right moments
- Evaluate the fit — at a certain income and complexity level, the CPA relationship should include proactive planning. If it consistently doesn’t, that’s worth addressing
The Bottom Line
RSU vesting is predictable. The income is coming. The tax consequence is set at the moment of vest. The only variable is whether anyone has looked at the schedule in advance and built a plan around it.
Getting your advisor and your CPA working from the same picture — before the vest, not after — is one of the highest-leverage things you can do with equity compensation. The window is always open before the event. It closes the moment the shares land.
