Spiff pay is a short-term cash bonus paid to a salesperson for completing a specific sale or hitting a narrow, pre-announced target, typically ranging from $20 to $200 per unit in industries like auto, electronics, and appliance retail. It is taxable income no matter who cuts the check, and in almost every case it has to be folded into the regular rate your employer uses to calculate overtime.
How a Spiff Actually Works
The defining feature of a spiff is the direct link between one completed sale and one specific payout. A store might offer $50 for every extended warranty sold over a holiday weekend. A manufacturer might pay $100 for each of its televisions moved off the floor that week. When the promotion ends, the bonus ends with it.
That transactional structure separates spiffs from base pay, commissions calculated on monthly volume, and profit sharing. Qualifying criteria are announced at the start of the promotion — usually in a memo, email, or sales dashboard — so employees know in advance exactly what triggers the payment. Common triggers include selling a specific model, attaching a warranty or protection plan to a sale, hitting a daily unit quota, or being among the first on the team to sell a set number of units.
The pre-announced nature of these criteria is not just an administrative detail. It’s what determines how the law treats the payment for overtime purposes.
Who Pays the Spiff
Spiff money comes from one of two places, and the source matters.
The first source is your direct employer. A retail store creates a spiff to clear aging inventory or push a high-margin product, sets the rules, and pays through its normal payroll system.
The second source is a manufacturer. When multiple brands compete for the same shelf space, a manufacturer may fund a spiff to encourage floor salespeople to recommend its product over a competitor’s. The manufacturer often sends the payment directly to the salesperson, bypassing the retailer’s payroll entirely. That funding split changes how the income gets taxed, and it can change what you owe.
How Spiff Pay Is Taxed
All spiff payments are taxable income. The IRS treats bonuses and awards for work performance as reportable income regardless of the payer.1Internal Revenue Service. Publication 525, Taxable and Nontaxable Income What differs is how the money is reported and what withholdings apply.
When Your Employer Pays
Employer-funded spiffs appear on your W-2 with your other wages. The employer withholds income tax, Social Security, and Medicare. For withholding purposes, the IRS classifies spiffs as supplemental wages, which employers may withhold at a flat 22 percent rate, or 37 percent on supplemental wages above $1 million in a calendar year.2Internal Revenue Service. Publication 15 (2026), Employer’s Tax Guide
When a Manufacturer Pays You Directly
Under IRS Revenue Ruling 70-337, bonuses paid by a manufacturer to a dealer’s sales employees are not treated as wages for employment tax purposes, because the manufacturer isn’t your employer. The payments are treated as compensation for services rendered to the manufacturer.3Internal Revenue Service. IRS Chief Counsel Memorandum That means the manufacturer doesn’t withhold Social Security or Medicare when it pays you.
For 2026, manufacturers must report these payments on Form 1099-NEC if the total paid to you exceeds $2,000 during the calendar year, up from the previous $600 threshold for payments made after December 31, 2025.4Internal Revenue Service. Form 1099 NEC and Independent Contractors Amounts in Box 1 of Form 1099-NEC are generally subject to self-employment tax, so you owe both income tax and the 15.3 percent self-employment tax covering Social Security and Medicare on those funds.5Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC
If the manufacturer doesn’t issue a 1099-NEC because the total falls under the reporting threshold, you still have to report the income on your tax return. The threshold decides whether the payer must file the form, not whether the money is taxable.
Why Spiffs Have to Be Included in Overtime
The Fair Labor Standards Act requires the “regular rate” used for overtime to include all compensation for work, with only a short list of statutory exceptions.6Office of the Law Revision Counsel. 29 U.S. Code 207 – Maximum Hours One exception covers truly discretionary bonuses — payments where the employer decides both whether to pay and how much at or near the end of the period, with no prior promise that would cause the employee to expect the payment.7GovInfo. 29 CFR 778.211 – Discretionary Bonuses
Spiffs almost never fit that exception. Because they’re announced in advance and tied to predetermined criteria, they’re nondiscretionary. Federal regulations specifically treat bonuses announced to encourage employees to work more efficiently or hit particular targets as nondiscretionary.8U.S. Department of Labor. Fact Sheet 17U: Nondiscretionary Bonuses and Incentive Payments Once the employer promises the bonus, even informally, that money has to be built into the regular rate for any workweek with overtime hours.
This applies whether your employer or a manufacturer funds the spiff. The FLSA defines the regular rate to include “all remuneration for employment,” so the source of the payment doesn’t relieve the employer of the recalculation duty.6Office of the Law Revision Counsel. 29 U.S. Code 207 – Maximum Hours
What the Recalculation Looks Like
The regulation requires the bonus to be spread back over the workweeks in which it was earned, with an additional half-time payment on the portion attributable to each overtime hour.9eCFR. 29 CFR 778.209 – Method of Inclusion of Bonus in Regular Rate
A simple example. You earn $20 an hour, work 50 hours in a week, and earn a $100 spiff that week. Without the spiff, your regular rate is $20 and your overtime rate is $30. With the spiff, the employer divides $100 by 50 hours, adding $2 to the regular rate. Your new regular rate is $22, and the employer owes an extra $1 per overtime hour (half of the $2 bump) for the 10 overtime hours. That’s an additional $10 on top of the overtime already paid.
Small on a single week. Not small once it repeats every pay period for months.
If Your Overtime Wasn’t Recalculated
An employer that leaves spiffs out of the regular rate violates the FLSA’s overtime provisions. The statute makes that employer liable for the full amount of unpaid overtime plus an equal amount in liquidated damages, effectively doubling the back pay. Courts may also award reasonable attorney’s fees and costs.10Office of the Law Revision Counsel. 29 U.S. Code 216 – Penalties
You can enforce these rights by filing a complaint with the U.S. Department of Labor’s Wage and Hour Division or by bringing a private lawsuit in federal or state court. The statute of limitations is two years from the date of the violation, or three years if the violation was willful.11Office of the Law Revision Counsel. 29 U.S. Code 255 – Statute of Limitations Many states add penalties for late or missing wage payments, including daily fines or damages calculated as a percentage of what’s owed.
If you regularly earn spiffs and also work overtime, pull your pay stubs from any week you hit more than 40 hours. Compare the overtime rate your employer used against your base rate plus the spiff earned that week. If the two don’t match, you likely have unpaid wages.
