Why is my bonus taxed so much?

Quick Answer

Bonuses appear heavily taxed because employers typically withhold at a flat 22% federal rate (plus state taxes and FICA). A $5,000 bonus has roughly $1,590 withheld total, but your actual tax liability depends on your annual income and tax bracket.

Why bonuses look heavily taxed


Bonuses aren't actually taxed at a higher rate — they're withheld at a higher rate. According to IRS Publication 15-T, employers must withhold federal taxes on supplemental wages (including bonuses) using either the flat rate method (22%) or the aggregate method. Most choose the simpler 22% flat rate, which often creates overwithholding.


Your bonus withholding includes:

  • Federal income tax: 22% (flat rate method)
  • Social Security: 6.2% (up to $176,100 wage base in 2026)
  • Medicare: 1.45% (plus 0.9% additional Medicare tax if over $200,000)
  • State tax: Varies by state (typically 3-8%)
  • Other deductions: Health insurance, 401(k) if elected

  • Example: $5,000 bonus withholding breakdown


    Let's say you earn $75,000 annually and receive a $5,000 year-end bonus:



    Why the 22% federal rate matters


    The 22% withholding rate is designed to cover most employees' actual tax liability, but it's often more than needed. If you're in the 12% tax bracket (single filers earning up to $48,475 in 2026), the 22% withholding creates a significant overpayment that you'll get back as a tax refund.


    Your actual tax bracket vs. withholding:

  • 12% bracket: 22% withholding = ~10% overwithholding
  • 22% bracket: 22% withholding = appropriate
  • 24% bracket: 22% withholding = slight underwithholding

  • The aggregate method alternative


    Some employers use the aggregate method, which treats your bonus as if it were regular wages. This can result in even higher withholding if the bonus temporarily pushes you into higher tax brackets for calculation purposes.


    Example: If your regular biweekly pay is $2,885 ($75,000 ÷ 26), adding a $5,000 bonus makes that paycheck $7,885. The system calculates withholding as if you earn $205,010 annually ($7,885 × 26), pushing you into higher brackets temporarily.


    Key factors affecting your bonus taxation


  • Your regular tax bracket: Lower brackets create more overwithholding
  • Bonus timing: Year-end bonuses may have different state tax implications
  • Bonus size: Larger bonuses may trigger additional Medicare tax (0.9% over $200,000)
  • Other income: Side hustles or investment income affect your overall tax picture
  • Withholding elections: Your W-4 doesn't affect bonus withholding rates

  • What you should do


    1. Don't panic about the high withholding — it's likely temporary overwithholding

    2. Calculate your actual tax liability using our paycheck calculator

    3. Adjust your W-4 if needed — if you consistently get large refunds, you may want to reduce withholding on regular pay

    4. Plan for the tax impact — set aside additional funds if you're in higher brackets

    5. Consider timing — discuss bonus timing with HR if you have flexibility


    Key takeaway: A $5,000 bonus typically has $1,500-1,800 withheld (30-36%), but your actual tax may only be 12-24% depending on your bracket. The difference comes back as a refund.

    Key Takeaway: Bonuses aren't taxed higher — they're withheld at 22% federal rate, often creating overwithholding that you get back as a refund if you're in a lower tax bracket.

    New workers receiving their first bonus who are confused by the high withholding

    Your first bonus can be shocking


    If you're earning $35,000-50,000 in your first job, you're likely in the 12% federal tax bracket. When your $2,000 year-end bonus has $600+ withheld (30%+), it feels like you're being penalized.


    Here's what's really happening:

    Your employer withholds 22% federal tax on bonuses regardless of your actual tax bracket. Since you're probably in the 12% bracket, you're overpaying by about 10 percentage points on the federal portion alone.


    Example: $40,000 salary + $2,000 bonus


  • Your actual tax bracket: 12%
  • Bonus withholding: 22% federal + 6.2% Social Security + 1.45% Medicare + state tax
  • Total withheld: ~$600-700
  • Actual tax owed on bonus: ~$240-360
  • Likely refund from overwithholding: ~$250-400

  • What this means for you


    1. You'll get money back — The overwithholding becomes part of your tax refund

    2. Don't adjust your W-4 yet — One bonus doesn't change your overall tax picture significantly

    3. Plan for next year — If you get regular bonuses, factor this into your financial planning

    4. Track your total withholding — Use your final paystub to see if you're on track for a refund or owe money


    Key takeaway: Entry-level employees typically get $250-400 back from bonus overwithholding because the 22% rate exceeds their actual 12% tax bracket.

    Workers with multiple W-2s who need to understand how bonuses affect their complex tax situation

    Multiple jobs complicate bonus withholding


    When you have multiple W-2 jobs, bonus withholding becomes more complex because each employer withholds taxes independently, without knowing your total income picture.


    The challenge: Each employer withholds as if their job is your only income. A $3,000 bonus from your part-time job gets the same 22% federal withholding, even though your combined income may push you into higher brackets.


    Example: Two jobs scenario


  • Job 1: $50,000 salary (primary)
  • Job 2: $20,000 part-time + $3,000 bonus
  • Combined income: $73,000 (22% bracket)
  • Problem: Job 2 withholds assuming you're in 12% bracket

  • Withholding on the $3,000 bonus:

  • Federal withheld: $660 (22%)
  • Actual tax owed: $660 (22% bracket) — happens to match!
  • But Social Security: Both jobs withhold separately up to wage base

  • Key considerations for multiple job holders


  • Underwithholding risk: Your combined income may put you in higher brackets than either employer assumes
  • Overwithholding on FICA: You may overpay Social Security if combined wages exceed $176,100
  • State tax complexity: Different states, different withholding rules
  • Estimated tax payments: May need quarterly payments if withholding falls short

  • What you should do


    1. Use the IRS Tax Withholding Estimator with your total projected income

    2. Complete Form W-4 carefully — check the multiple jobs box and follow instructions

    3. Monitor your total withholding — track across all employers

    4. Consider making estimated payments if you consistently owe at tax time


    Key takeaway: Multiple job holders face higher risk of underwithholding overall, even though individual bonuses may still be overwithheld at 22%.
