Can You Write Off Employee Bonuses? Limits, Timing, and Reporting

Yes, an employee bonus tax deduction is available to virtually every business that pays performance pay, signing bonuses, or year-end rewards. Bonuses qualify as compensation under Internal Revenue Code Section 162, the same provision that covers salaries and other ordinary and necessary business expenses.¹ The deduction is straightforward in principle. What trips businesses up is the fine print: when the deduction lands in a given tax year, how the rules change for owner-employees, and the payroll tax obligations that ride along with every bonus dollar.

What Qualifies as a Deductible Bonus

A bonus is deductible when it meets the Section 162 test: ordinary and necessary for your trade or business, and paid as compensation for services the employee actually performed.¹ “Ordinary” means common and accepted in your industry. “Necessary” means helpful and appropriate for the business. A performance bonus, a signing bonus, a spot award, or a profit-sharing payout all clear that bar without difficulty.

Trouble starts when a payment looks less like pay for work and more like a way to move money out of the company. The IRS watches closely for bonuses that are really disguised dividends, especially in closely held corporations where the same people set compensation and receive it. If a C-corporation pays its owner-employee a $500,000 bonus in a year the company earned $510,000, auditors are going to have questions. The excess portion gets reclassified as a nondeductible distribution.

One trap on the smaller end: cash and cash equivalents given as holiday gifts don’t qualify for de minimis fringe treatment, no matter how modest the amount. A $25 gift card is taxable supplemental wages that must be reported and withheld on just like a cash bonus.² If you hand out gift cards, put them through payroll.

The Reasonable Compensation Ceiling

Even a bonus clearly tied to real work can be disallowed if the total compensation package is unreasonable. The IRS asks whether a similar business would pay a similar amount for similar work under similar circumstances.³ Relevant factors include the complexity of the work, the employee’s qualifications, hours worked, and what comparable businesses pay for the role.

This test bites hardest in closely held businesses. When the person approving the bonus also receives it, the IRS looks at whether an independent investor would consider the total pay reasonable given company revenue and the employee’s actual contributions. If the package fails, the excess is disallowed. For C-corporations, that excess is typically recharacterized as a dividend: the company loses the deduction and the recipient still owes tax on the money.

Publicly traded companies face a separate hard cap. Section 162(m) limits deductible compensation to $1 million per year for covered employees such as the CEO, CFO, and other top officers, and bonuses count toward that ceiling alongside salary.⁴ Anything above $1 million is simply not deductible for those employees.

When the Deduction Hits Your Return

The tax year in which you claim the deduction depends on your accounting method. Getting this wrong is one of the more common and entirely avoidable mistakes.

Cash-Basis Businesses

If you use the cash method, you deduct the bonus in the year you pay it. A check issued in December 2026 belongs on the 2026 return. A check issued in January 2027 belongs on the 2027 return. There’s no way to pull the deduction into an earlier year.

Accrual-Basis Businesses

Accrual filers can deduct a bonus in the year it’s earned rather than the year it’s paid, but the liability must satisfy the all-events test before year-end. That test has three parts: all events establishing the obligation have occurred, the amount can be determined with reasonable accuracy, and economic performance has taken place.⁵ The employee must have finished the qualifying work, and the bonus formula must produce a calculable number by December 31.

Now the catch. Under Section 404, compensation not paid in the same year it accrues is generally treated as deferred compensation, deductible only when the employee reports it as income.⁶ The escape hatch is the 2.5-month rule: if you pay the accrued bonus within two and a half months after the fiscal year closes (March 15 for calendar-year filers), the IRS treats it as paid during the accrual year and the current-year deduction stands. Miss that window and the deduction slides into the following year.

Bonuses Paid to Owners and Shareholder-Employees

The timing rules change once the recipient owns a meaningful piece of the business. Section 267 requires that when the payer and recipient are related parties, the business can only deduct the bonus in the year the recipient reports it as income.⁷ “Related party” includes any individual who owns more than 50% of a corporation’s stock. Because most individual owners file cash-basis, the practical result is that the company can’t deduct the bonus until it actually pays you. The 2.5-month rule doesn’t override this matching requirement.

The same matching rule reaches personal service corporations and their employee-owners even at ownership below 50%.⁷ If your entity is a personal service corporation in consulting, accounting, health, or law, assume the matching rule applies to any bonus you pay yourself.

S-corporation shareholder-employees draw extra scrutiny. Payments to a corporate officer who is also a shareholder must be treated as wages to the extent they represent reasonable compensation for services.⁸ Labeling what should be wages as “distributions” to sidestep payroll taxes doesn’t work. Pay yourself a fair wage and bonus first; take distributions after.

Payroll Taxes and Withholding

Bonuses are supplemental wages, and they carry the same payroll tax obligations as regular pay.⁹ Handing an employee a bonus check without running it through payroll creates a liability that compounds fast with penalties and interest. Every bonus dollar goes through payroll.

Federal Income Tax Withholding

You can withhold federal income tax on bonuses at a flat 22%, as long as total supplemental wages paid to the employee during the calendar year stay at or below $1 million. The excess above $1 million is withheld at 37%.⁹ Those rates were permanently extended by P.L. 119-21.

Social Security and Medicare

Both the employer and the employee owe 6.2% for Social Security on earnings up to $184,500 in 2026, plus 1.45% each for Medicare with no wage cap.¹⁰ If the employee has already earned above the Social Security wage base from regular pay, no additional Social Security tax applies to the bonus. An additional 0.9% Medicare tax applies to employee wages above $200,000 for the year, with no employer match on that portion.

Federal Unemployment Tax

FUTA runs 6.0% on the first $7,000 of wages per employee per year, though most employers qualify for a 5.4% credit that brings the effective rate to 0.6%.¹¹ By the time year-end bonuses go out, most employees are well past $7,000, so FUTA often adds nothing to the bonus cost. State unemployment taxes also apply, with rates varying by state, industry, and claims history.

The employer’s share of FICA and FUTA is itself deductible, so build that into your budgeting for the total cost of a bonus.

Documentation That Holds Up in an Audit

Clean records separate a deduction that survives an audit from one that doesn’t. No single document is required, but you need enough to show the bonus was authorized, calculated according to a plan, and processed through payroll.

A written bonus plan or employment agreement spelling out how bonuses are calculated, what triggers them, and when they’re paid. A discretionary bonus is still deductible, but a documented formula makes it much harder for the IRS to argue the payment was a disguised distribution.
Corporate authorization. For corporations, board minutes or a written resolution approving the bonus program before year-end. This matters most for accrual-basis businesses claiming a current-year deduction on bonuses paid after December 31.
Payroll records showing the gross bonus, withholdings for federal income tax, Social Security, and Medicare, and the net payment to the employee.
Performance data supporting the calculation when the bonus is tied to metrics like revenue targets or project milestones.

Accrual filers taking a current-year deduction on a bonus paid the following year should treat the timing documentation as the most important piece. The board resolution or plan should be dated before year-end, and the underlying performance metrics should be calculable from year-end financial data. Auditors look here first.

Reporting the Deduction

On the business return, bonuses are reported as part of total employee compensation, on the line matching your entity:

C-corporations report bonuses on the Salaries and Wages line of Form 1120.¹²
S-corporations report on Form 1120-S.
Partnerships report on Form 1065, which passes the deduction through to each partner.¹²
Sole proprietors record the expense on Schedule C of Form 1040 as part of labor costs.

Every bonus must also appear on the employee’s Form W-2. The amount is included in Box 1 (wages, tips, other compensation), Box 3 (Social Security wages), and Box 5 (Medicare wages and tips), with the corresponding withholdings in the applicable tax boxes.¹³ Leaving a bonus off the W-2 creates problems at filing time for both sides, and the IRS cross-references payroll tax deposits against W-2 totals to catch discrepancies.
