Did You Know a $10K Relocation Benefit Can Turn Into $15K With Poor Gross-Up Handling?

Offering a $10,000 relocation bonus may seem like a simple, generous benefit—but if your gross-up process is poorly managed, that $10K can easily cost your company $15,000 or more.

This hidden expense is more common than many HR and payroll teams realize—and as year-end approaches, gross-up accuracy is mission-critical.

Let’s break down how a well-intentioned relocation payment can balloon due to tax miscalculations, and how your team can avoid it.

What Is a Gross-Up, Really?

A tax gross-up is when an employer increases a taxable payment (like a relocation bonus or housing allowance) to cover the employee’s tax liability—ensuring they receive the full intended benefit after taxes.

For example, if you offer an employee $10,000 to help with their relocation and don’t gross it up, they may only receive around $7,000 after taxes. To “make them whole,” you might gross it up to around $13,000 depending on tax rates.

But if your calculations are off—or if you're layering gross-ups on gross-ups—you can end up overpaying by thousands.

How a $10K Benefit Turns Into $15K

Here’s how a simple relocation payment becomes a bloated line item:

Individually, these errors might seem small. But together, they can turn your $10,000 benefit into a $15,000 tax-time regret.

Real Cost, Real Risk

Aside from bloated spend, poor gross-up handling introduces:

  • W-2 inaccuracies

  • Time-consuming January corrections

  • Frustrated employees with unexpected tax bills

  • Compliance exposure during audits

And most of it is preventable with the right tools and processes in place.

What Smart Teams Are Doing in Q4

As year-end approaches, top HR and finance teams are already:

  • Auditing all relocation-related taxable payments

  • Aligning with payroll on what’s been reported YTD

  • Switching from flat-rate to marginal gross-up models

  • Partnering with providers who understand global compliance nuances
