RSU Tax Planning for Tech Employees

Your RSUs are taxed the moment they vest. The 22% withholding almost never covers it.

Restricted Stock Units are taxed as ordinary income at vesting — not when you sell. The IRS default withholding of 22% leaves engineers in the 35–37% bracket with a gap that compounds across every vesting event. Here's how to plan around it.

The problem isn't that RSUs are complicated. It's that the default system works against you.

The withholding gap compounds every vesting event

The IRS withholds 22% on supplemental income like RSUs — but if you're in the 35% or 37% bracket, every vest event leaves a gap. That gap compounds across quarterly vesting schedules. Most engineers don't see the total until April.

You've done everything right — and still get surprised

You've built a career at a top-tier employer, earned real equity, and done the hard work. Getting blindsided by a five-figure tax bill isn't failure — it's a planning problem that nobody warned you about.

Nobody warned you what was coming

It's wrong that engineers who built real company value lose a third of it to taxes nobody explained in advance. A proactive strategy isn't a luxury — it's what every vesting event requires.

RSU planning requires more than a tax return. It requires a proactive quarterly strategy.

“You've spent years earning equity that could change your family's financial future — and the fact that you're not sure what to do with it doesn't mean you're not smart enough. It means nobody built you a clear map.”

The EQUITY System™ wasn't designed in a classroom — it was built working directly with engineers at unicorn startups and companies like Amazon, where the stakes of getting it wrong were real.

Mitchell Ludwig, CFP® built his practice around one problem: helping tech professionals turn equity compensation into lasting wealth. Every client relationship begins with equity — the strategy is built around it from day one.

  • Works exclusively with tech professionals and equity compensation
  • Deep specialization in ISO, RSU, ESPP, AMT, and QSBS
  • No generic portfolios — every strategy is equity-compensation-first
  • Direct advisor relationship — you work with Mitchell, not a junior associate

Most advisors see RSUs as income. I see them as a 3–5 year tax and diversification problem that needs a plan today.

The RSU Planning Framework

Before each vest event — not after.

Quarterly Tax Projection

Know your real tax rate before the vest event — not after.

Before each vesting event, we model your effective rate vs. withholding. We build a real-dollar projection accounting for your bracket, FICA cap, state taxes, and existing AGI. No surprises in April.

Sell-or-Hold Decision Framework

Every vest event is a decision. Make it with a framework, not a gut feeling.

Sell immediately to diversify, or hold and take concentration risk? We build the framework — based on your timeline, other income, and position size — before the grant vests so you never make this call under pressure.

IPO, Acquisition & Lockup Planning

Special events change RSU taxation entirely. Plan for them before they happen.

IPOs, acquisitions, and lockup expirations create high-stakes tax decisions under time pressure. We map blackout windows, lockup dates, and post-IPO diversification schedules as part of your plan — not an afterthought.

Common questions about RSU taxation

How are RSUs taxed at vesting?
RSUs are taxed as ordinary income at vesting based on the fair market value of the shares on the vest date. The IRS applies 22% supplemental withholding (37% above $1M in supplemental income in a year), which frequently leaves engineers in the 35–37% bracket with an underpayment.
What is the RSU withholding rate?
The IRS mandates 22% supplemental withholding on RSUs (37% for supplemental income above $1M in a calendar year). Engineers in the 35–37% marginal bracket routinely face underpayment and should adjust quarterly estimated tax payments accordingly.
Should I sell RSUs immediately when they vest?
Selling immediately (same-day or same-week sale) converts concentrated company stock into cash and eliminates additional share price risk beyond the vest date tax event. Whether to hold depends on your financial plan, position size, tax situation, and diversification needs.
Do RSUs trigger AMT?
No. RSUs vest as ordinary income and do not create an AMT preference item. AMT applies to ISO exercises, not RSU vesting events. RSUs affect your regular tax liability but not your alternative minimum tax calculation.
