Austin has no shortage of opportunities to participate in the growth of a company. That often shows up through performance-based bonuses, receiving restricted stock units (RSUs), or the ability to participate in an Employee Stock Purchase Plan (ESPP).

Each of these can be a meaningful way to build wealth over time. But as compensation shifts beyond just cash, the tax implications become more important. Without a clear plan in place, it’s easy to end up with an unexpected tax bill or miss opportunities to manage it more effectively.

What is a withholding?

Before getting into potential tax implications of bonuses, RSUs, or ESPP it’s important to know what withholdings are. Withholdings are simply instances of the IRS collecting taxes throughout the year but it’s based on estimates, not your full tax picture. That’s why even with taxes being withheld, you can still end up owing more at the end of the year.

Bonuses

Income that may have originally been projected to fall within the 24% bracket can quickly move into the 32% bracket once a bonus is factored in. An 8% increase may not sound significant at first, but when that higher rate applies to a larger portion of your income throughout the year, it can create a meaningful gap between what’s been withheld and what you actually owe.

Because the withholding may not automatically adjust, many people get caught off guard in April.

Tax-smart moves

  • Review your tax situation to make sure you’re not losing any deductions.
  • Run a quick projection to see if you need to adjust withholdings.
  • Consider estimated payments if your withholdings aren’t enough to avoid penalties.

RSUs

RSUs can be a common way for companies to reward employees. You may see them labeled differently such as a Leadership Stock Plan (LSP) or Performance Stock Units (PSUs), but regardless of the name, the tax treatment is generally the same.

A helpful way to think about RSUs is as a bonus paid in stock instead of cash. Withholding is still applied, but it’s often done at a fixed rate which offers less flexibility compared to other forms of compensation. As a result, it’s possible to still owe a meaningful amount at tax time, even though taxes were already withheld.

Tax-smart moves

  • Have a plan to build up cash to cover any remaining tax liability.
  • Coordinate with your advisor once you receive your grant with vesting schedules.
  • Review cost basis to avoid double taxation.

ESPPs

An ESPP can be a valuable benefit because it allows you to purchase your company stock at a discount. Unlike Bonuses and RSUs you must elect to participate in the plan.

Contributions are made with after-tax dollars, so participating doesn’t increase your taxable income. Instead, the tax impact comes later when you decide to sell the shares.

Tax Smart Moves

  • Be aware of the qualifying disposition date of each lot purchased.
  • Use harvested losses to offset gains.
  • Strategically plan when you sell to avoid additional taxes like the Net Investment Income Tax.
