Shares Were Withheld for RSU Taxes. So Why Do You Still Owe?

For many Stryker employees, restricted stock units are an important part of their overall compensation. When RSUs vest, a portion of the shares is typically withheld for taxes. It is natural to look at the transaction and assume the tax obligation has been fully addressed.

Then April arrives. Your CPA completes your return, and you learn that you owe another $20,000, $30,000, or more. This is one of the most common tax-related surprises we discuss with Stryker employees. The issue usually is not that something went wrong. It is that tax withholding and tax planning are two different things.

I recently recorded an episode of Retirement Blueprint explaining why the taxes withheld from an RSU vest may not cover your final tax bill and how proactive planning can help you prepare.

What Happens When Your RSUs Vest?

Suppose $200,000 worth of your Stryker RSUs vest during the year. You generally will not receive the entire value in shares. Instead, a portion of the shares may be withheld to cover federal income taxes, payroll taxes, applicable state taxes, and other required withholding.

Seeing those shares withheld can create the impression that your taxes have been fully paid. However, withholding is only an estimate applied to that particular compensation event.

Your final tax liability is calculated using your entire tax return. That includes your salary, bonus, RSU income, stock option exercises, investment income, spousal income, and other taxable activity during the year. The amount withheld from your RSUs may be reasonable for the vesting event but still fall short once everything is combined.

Why Withholding May Not Match Your Final Tax Bill

RSU income is generally treated as supplemental wages for federal income tax withholding purposes. The withholding method used by an employer may not reflect the marginal tax rate that ultimately applies to your household’s total income.

This difference can be particularly important for highly compensated employees. A significant bonus, several RSU vesting events, or a stock option exercise can increase taxable income considerably.

Imagine that two employees receive RSUs during the year. One has $30,000 vest, while the other has $400,000 vest. Both may have shares withheld for taxes, but the larger vesting event could create a much greater difference between the amount withheld and the employee’s final tax liability. The larger and more complex your compensation becomes, the less effective it may be to rely on automatic withholding alone.

How a Tax Projection Can Help

One of the most valuable planning conversations we can have during the year is a tax projection meeting. It is not because taxes are particularly exciting. It is because surprises are not. A tax projection brings together your expected salary, bonus, equity compensation, investment income, retirement contributions, charitable giving, taxes already withheld, and other relevant information. The objective is to estimate where your tax situation may be heading before the year is over.

If the projection identifies a potential shortfall, there may still be time to consult with your tax professional about increasing withholding, adjusting estimated tax payments, or setting aside additional cash. A projection does not necessarily reduce the taxes you owe. It helps you understand and prepare for them.

A Hypothetical Example

Consider Jennifer, a hypothetical Stryker employee who has a strong year. She receives a sizable bonus, has several RSU vesting events, and exercises a portion of her stock options. Taxes are withheld from her compensation, so she assumes everything has been covered. When her tax return is completed, however, she learns that she owes an additional $28,000. No single transaction caused the entire shortfall. The combination of her salary, bonus, RSUs, stock option income, and other household income created a larger tax bill than the amount withheld could cover.

The following year, Jennifer prepares a tax projection in September with her financial and tax professionals. Based on the projection, she adjusts her tax payments before year-end and reserves the cash she expects to need. When April arrives, she is prepared. The projection did not dramatically lower her taxes. It gave her clarity and time to plan.

Taxes Are Only One Part of the Decision

Tax planning should not focus solely on paying the least amount of tax in the current year. The broader objective is to make financial decisions that support your long-term goals. Sometimes accelerating income may make sense. In other situations, delaying a transaction may be more appropriate. Charitable giving, retirement contributions, and the timing of stock option exercises may also affect the analysis.

Taxes should be considered alongside your cash-flow needs, retirement timeline, investment strategy, and family priorities. A decision that produces the lowest immediate tax bill is not automatically the one that creates the strongest long-term outcome.

Consider Your Investment Strategy After the Vest

An RSU vest is not only a tax event. It also presents an investment decision. Once the shares vest, you should consider whether continuing to hold Stryker stock makes sense within your broader portfolio. Long-time employees may already have significant exposure to the company through their salary, bonus, RSUs, stock options, retirement-plan holdings, or previously vested shares.

Retaining shares after every vesting event can gradually create a concentrated position without the employee making a deliberate decision to do so. Before your next vest, consider how much taxable income the event may create, whether your current withholding is likely to be sufficient, and what you intend to do with the shares afterward. Tax planning and investment planning should work together.

Final Takeaway

The most important takeaway is simple: Do not confuse tax withholding with tax planning. Withholding happens automatically. Planning happens intentionally. When your compensation includes salary, bonuses, RSUs, stock options, and investments, relying solely on automatic withholding may lead to an unwelcome surprise. A tax projection completed before year-end can help you understand your potential liability, prepare for the amount you may owe, and coordinate your equity compensation with your broader financial plan.
