Every year, thousands of Indian professionals working at global companies open their brokerage accounts and watch free shares land in them. It feels like manna from heaven and it probably is!

But for most people, RSUs and ESOPs quietly cross a line from "wealth creation" into "wealth concentration" and almost nobody notices the exact moment it happens.

When your salary, your bonus, your career growth, and your investment portfolio all depend on a single entity, you haven't built wealth. You've built a single point of failure.

How Concentration Happens Without a Decision

Nobody consciously chooses to put a third or half of their net worth into one company's stock. It happens by default.

RSUs vest on a schedule, typically 25% a year over four years. Every vesting date adds more shares to an already growing pile. There's no single moment where a person sits down and asks, "Do I actually want this much exposure to one stock?" The shares simply accumulate, quarter on quarter, year after year, until one day the number is quite large. But selling to ease concentration is not something that most want to consider.

What is standing in the way are the emotions. "This is my company. I believe in it. Why would I sell?" It's a natural thought, and often a genuine one. And at this point it is hard to tell if you are holding on to the shares because you really believe in the company or if you are just emotionally invested in the shares that now form a good part of your wealth.

Holding because you've done the analysis and believe the valuation still has room to run is conviction. Holding because selling feels like betrayal, or because you haven't gotten around to it, is inertia wearing conviction's clothes.

The result is the same either way: concentration risk that is staring in the face, which one does not want to look in the eye.

Tax Impact: Two Bites, Not One

Most employees think of RSUs/ESOPs taxation as a single event. It isn't, there are two distinct tax moments, and both matter.

• Bite One: At Vesting (or Exercise): When your shares become yours, their value is treated as a perquisite and added to your salary income. This is taxed at your slab rate, for most senior professionals, that's the highest bracket. This tax is usually deducted at source by selling a portion of your shares before you ever see them, just to cover the liability.
  The perquisite calculation differs slightly by instrument:
  RSUs: You pay nothing to acquire the shares, so the entire fair market value at vesting is treated as perquisite and taxed as salary income.
  ESOPs: You typically pay an exercise price to acquire the shares (often at a discount to market value). Only the difference between the fair market value and the price you paid is treated as perquisite and taxed. Your exercise price itself becomes your acquisition cost for the next step.
  


• Bite Two: At Sale: When you eventually sell, you owe capital gains tax on the difference between the price at vesting/exercise and the price at sale. Whether this is short-term or long-term and taxed accordingly depends on how long you've held the shares since vesting/exercise.
  Because the first tax bite already happened at vesting, employees start thinking of the remaining shares as "pure profit." Selling now feels like giving up a bonus rather than rebalancing a portfolio. That bias pushes people to hold longer than they should right at the point where concentration is largest and risk is highest.
  

The Inheritance Tax Blind Spot

This is the piece almost nobody accounts for, and it deserves more attention in client conversations than it currently gets.

If you're an Indian resident holding shares of a US-listed company through RSUs or ESOPs from a US employer, those shares are classified as US situs assets. Upon death, they can trigger the US estate tax, regardless of your nationality or residency.

The exemption for non-resident, non-citizens is roughly $60,000. Cross that $60,000 threshold, and the tax on the excess can run as high as 40%.

Consider what this means. This rule does not impact day traders; this impacts precisely the most disciplined professionals who played by the book. They rode out the market cycles, they held onto their assets loyally and patiently and let their portfolio grow over years, even decades. And the greater and more successful their holdings become, the more exposed their estates become. This exposure increases as success increases, and hardly anyone plans for this because hardly anyone talks about it until it becomes relevant.

This is not an abstract concern applicable only to Indian professionals who work at US-listed multinationals. This is simply the nature of investing in US stocks as a foreign citizen, and it deserves as much consideration as any other form of estate planning.

The Double-Edged Sword

Put the three risks together, and the picture becomes clear:

Employer risk if the company underperforms, your salary growth, your bonus, and your portfolio value all stall at the same time. There's no offsetting engine. When one part of your financial life gets hit, all of it does.

Country and structure risk holding US-listed shares as an Indian resident adds US estate tax exposure and ongoing compliance obligations (like Schedule FA foreign asset disclosure), layered on top of the concentration itself.

The behavioral risk, loyalty makes you confused with commitment and thus you delay the one decision (Diversification) that would really preserve your already gained wealth.

None of these risks are visible on a statement. They only become visible when something goes wrong, and by then the options are far more limited.

Why Diversification Isn't Optional Here

Diversification is seen as a generic piece of investment advice that few people agree to when offered. When RSUs and ESOPs are the subject matter, diversification is far from generic. In fact, it is the solution to every risk mentioned above.

A quick test: would you buy this much of your employer's stock today, in cash, if you didn't already hold it? If the answer is no, then the amount in excess of what you would invest yourself is not conviction. It is simply inertia, and it's sitting in your portfolio only because it arrived there automatically.

For those who desire access to US markets without owning US-listed stocks and avoiding the estate taxes associated with such holdings, structural options can be considered. Options such as funds based in GIFT City and in Ireland enable individuals to access US equities yet remain structurally different under US estate tax law.

Redefining "Reward"

RSUs and ESOPs are not free wealth. They are deferred compensation taxed twice, tied to a single employer, and, in the case of US-listed shares, carrying an inheritance tax exposure that most people never see coming until it's their family dealing with it.

None of this means RSUs and ESOPs are a bad thing. They can be a genuine engine of wealth creation, but only if they're treated as compensation to be actively managed, not as an investment to be passively held out of loyalty.

The reward isn't the grant. It's what you do with it afterward.
