What to Do With a Windfall or Bonus: A Step-by-Step Order

Short answer: when you receive a windfall or bonus, park it in savings for a few days, work out the after-tax amount, then use a set order: build a $1,000 starter fund, pay off high-interest debt, add to retirement, save for a near goal, and keep about 10% for enjoying now. A plan made before the money arrives beats a decision made in the excitement.

Key takeaways

  • Bonuses are usually withheld at a flat 22% federal rate, but the withholding is not your final tax. The true tax is settled when you file.
  • A set order protects you: starter fund, expensive debt, retirement, near goals, then fun.
  • Paying off a 24% card with $2,000 saves about $480 in interest over a year, a return that is hard to match elsewhere.
  • Keep a slice to spend on purpose. A plan with no fun in it tends to fail.

How is a bonus taxed?

If a bonus is paid separately from regular wages, an employer can withhold federal income tax at a flat 22% (it rises to 37% on supplemental wages above $1 million in a year). If it is added to a regular paycheck, the employer may instead combine it with your usual pay and withhold using your W-4. Either way, Social Security (6.2%) and Medicare (1.45%) apply, and most states take their share.

Here is a $10,000 bonus with an assumed 5% state tax, for illustration:

ItemAmount
Bonus before tax$10,000
Federal withholding, 22%-$2,200
Social Security, 6.2%-$620
Medicare, 1.45%-$145
State tax, 5% (example)-$500
Arrives in your account$6,535

That is 65.4% of the headline figure. Withholding is not the final bill. If your actual tax rate is lower than 22%, you may get some back when you file, and if it is higher, you may owe more. Plan around the after-tax amount, not the headline. See how to read a pay stub to see these lines on your own stub.

What are the five steps for the money?

  1. Pause and park it. Put it in a high-yield savings account for a few days. Decide with a clear head, and avoid spending against a figure you have not yet received.
  2. Build a starter fund. If you have less than $1,000 in emergency savings, fill it first. See how to build an emergency fund.
  3. Pay high-interest debt. Cards at 20% or more come before investing. See how to pay off credit card debt fast.
  4. Add to retirement. A Roth IRA or extra 401(k) contribution lets the money grow for decades. See Roth IRA vs 401(k).
  5. Fund a near goal and enjoy some. A down payment, a trip or a car fund, and a planned treat.

What does a sample split of $5,000 look like?

Here is an example for someone with a thin emergency fund and a 24% card balance.

UseAmountShareWhat it does
Starter emergency fund$1,00020%Covers a surprise without a card
Pay down the 24% card$2,00040%Saves about $480 of interest in a year
Retirement (Roth IRA)$1,50030%Grows to about $11,418 in 30 years at 7%
Enjoy it$50010%A planned treat with no guilt

If you have no high-interest debt, shift that $2,000 to the retirement or near-goal lines. If your starter fund is full, extend it toward three to six months of spending. Your own split depends on your debts and goals.

How do you handle other kinds of windfall?

  • Tax refund. It is your own money returned. A refund every year can mean too much is withheld, which you can adjust on your W-4.
  • Inheritance. Inherited money is usually not taxed as income to the person receiving it, but retirement accounts follow separate rules. Wait, ask a tax professional about those accounts, and avoid big decisions for a few months.
  • Gift or settlement. Tax treatment varies, so check before spending.
  • Raise. A raise is a repeating windfall. Send half of it to savings before it becomes normal spending. See how to stop lifestyle inflation.

If the amount is large and your situation is complex, a fee-only fiduciary can help you think it through. See how to choose a financial advisor.

Frequently asked questions

What should I do with a windfall?

Park it in savings for a few days, then follow an order: a $1,000 starter fund, high-interest debt, retirement, a near-term goal, and about 10% for enjoying now. Plan around the after-tax amount.

How are bonuses taxed?

Federal withholding on a separate bonus is commonly a flat 22%, plus Social Security, Medicare and any state tax. The withholding is not the final tax, which is settled on your return. A $10,000 bonus might net about $6,535.

Should I pay off debt or invest a bonus?

High-interest debt usually comes first. Paying off a card at 24% earns a certain 24% in avoided interest, which beats typical investment returns. Low-rate debt such as a 4% mortgage can wait while you invest.

Is it okay to spend part of a windfall?

Yes. Setting aside about 10% to spend on purpose makes it easier to stick to the rest of the plan. Decide the amount before the money arrives so it does not become the whole thing.

Is an inheritance taxable?

Inherited money is usually not taxed as income to the person receiving it, though estate and state rules vary, and inherited retirement accounts follow separate rules. Check with a tax professional before spending.
