How Bonuses Are Taxed in Maryland (2026)

You earned a $10,000 bonus. You expect: "$10,000 in my account." But when the deposit hits, it's closer to $6,000–$7,000. Your first thought was that Maryland taxes bonuses at some punishing special rate — and you are not alone in that panic.

But the math behind a bonus is far less sinister than the withholding makes it look. Maryland has no separate bonus tax at all. The bonus was not reduced. Taxes were prepaid through withholding. Here is exactly what happened, and how to see your real number on the Maryland Bonus Tax Calculator.

Maryland Does Not Have a Bonus Tax

Let's clear this up first, because it causes the most stress. A bonus is ordinary income. It stacks on top of your salary and is taxed at your marginal rate — the same federal brackets, the same Maryland state brackets, and the same county piggyback rate that hit your regular paycheck.

There is no special "bonus rate" in Maryland law. The number that scared you is a withholding rule, not a tax rate.

Why 22% Got Taken Out

Here is the reality. The IRS lets employers treat bonuses as "supplemental wages" and withhold federal tax at a flat 22% (for bonuses under $1 million). It is a shortcut that keeps payroll simple — not a calculation of what you owe.

A lot of people think: "My bonus was taxed at 22%," believing that is their final tax rate. It is not. The 22% is just a common federal withholding method for bonuses. Your actual tax depends on your total yearly income. Someone in a higher bracket may owe more later, while someone in a lower bracket may get money back.

ProTip: The flat 22% only covers the federal slice. Maryland state tax, your county tax, and FICA still come out on top of it. That is why a bonus often nets closer to 60% than the 78% the 22% figure implies. The fix many people miss: ask payroll to route the bonus into your 401(k) or HSA, which shields it from federal, state, and county income tax entirely.

What You Actually Keep

Think of it this way — the true cost of a bonus is the tax on your salary plus the bonus, minus the tax on your salary alone. That difference is your real bonus tax.

For a single filer earning $75,000 in Howard County (3.20%), a $5,000 bonus breaks down roughly like this:

• Federal (22% bracket): ~$1,100
• Maryland state (4.75%): ~$238
• County (3.20%): ~$160
• Social Security + Medicare: ~$383
• You keep: about $3,120 — roughly 62% of the bonus

To accurately calculate bonus tax Maryland style, the Maryland Bonus Tax Calculator runs this for your salary, county, and bonus instantly, and shows both the flat-22% withholding and your true marginal cost side by side.

Bonuses Over $1 Million

The rule changes at the top. The portion of supplemental wages above $1 million is withheld federally at 37%, not 22%. This affects very few workers, but if you are in that tier, expect a much larger up-front federal bite.

Before You Spend It

A few realities worth knowing before that money lands:

• FICA always applies. Your bonus is subject to the full 7.65% Social Security and Medicare, just like salary.
• Your county still matters. The same local rate that shapes your paycheck shapes your bonus.
• It can push you up a bracket. Remember the staircase analogy: Your tax bracket is like a staircase. Not every dollar gets taxed at the highest step. If someone enters a higher bracket, they don't suddenly lose more money on everything. Only the dollars above that threshold are taxed at the higher rate. Withholding is just an estimate, not your final bill.
