Pay bonuses before year-end if you want the deduction this year and the people receiving them are employees rather than owners. Sound year-end bonus tax planning turns on three things: whether your business is on the cash or accrual method, whether the bonus is fixed by December 31, and who is being paid. Bonuses to employees generally work. Bonuses to yourself as an owner frequently cost more in payroll tax than they save in income tax, which is the part that surprises people. And a deduction that creates a January cash shortage is not a win.
This question arrives every December in roughly the same form. Profit came in ahead of plan, the owner wants to reduce the tax bill, and a bonus feels like the obvious move because it rewards the team and lowers income at the same time. Sometimes that is exactly right. Harness Advisory Platform runs the numbers in October instead, because by late December the answer is whatever the calendar allows rather than whatever is best.
It reduces business income by the amount of the bonus plus the employer payroll tax on it. Whether that lands in this year or next depends entirely on your accounting method and on how the bonus is structured.
If your business is on the cash method, the rule is simple. You deduct the bonus when you pay it. A bonus declared in December and paid in January is a January deduction, full stop.
If you are on the accrual method, you may be able to deduct a bonus this year that you pay next year. Under Section 461, a liability is deductible once the all events test is met and economic performance has occurred, and the regulations allow compensation accrued at year end to be deducted in that year if it is paid within two and a half months after the close of the year. Miss that window and the amount is treated as deferred compensation, deductible only when paid.
The liability has to be fixed at year end, and this is where most accruals fail. If the bonus is entirely discretionary as of December 31, or the plan says an employee forfeits the bonus by leaving before the payment date, the amount is not fixed and the current-year deduction generally is not available.
The IRS addressed the common workaround in Revenue Ruling 2011-29. A business can fix the total bonus pool by year end, even if individual allocations are not final, provided that amounts forfeited by departing employees are reallocated among the remaining participants rather than returned to the company. If the company keeps the forfeited amount, the total was never fixed.
The practical version: the board or owner needs to approve a defined pool before December 31, in writing, with language that reallocates forfeitures. That is a fifteen minute task that has to happen before the year closes, and it cannot be recreated in February.
Because of the related party rule in Section 267. An accrual-basis business generally cannot deduct accrued compensation payable to a related cash-basis recipient until the recipient includes it in income. For S corporation shareholders and for more-than-50-percent owners of C corporations, that means an owner bonus is deductible when it is actually paid, not when it is accrued.
So the two-and-a-half month strategy works for your staff and not for you. Your own bonus has to clear payroll by December 31 to count this year.
Four ways, and the first one catches owners most often.
Add the employer share of Social Security and Medicare at 7.65 percent on top of every dollar. Federal and state unemployment tax usually does not apply to a December bonus for an existing employee, since those wage bases are typically exhausted earlier in the year, though that changes for anyone hired recently.
Withholding is the piece that generates the most questions from employees. Bonuses are supplemental wages, and employers commonly apply a flat federal withholding rate rather than running them through the regular tables, as described in IRS Publication 15. The result is a check that looks smaller than the employee expected, which is worth explaining in advance rather than after.
There is also a retirement plan effect. Bonus compensation generally counts as plan compensation, which can increase employer contributions under a profit sharing or match formula. That is a cost, and depending on your design it may also be a benefit you were going to fund anyway.
They are not interchangeable, and comparing them on deduction size alone leads to poor decisions. A bonus delivers cash to a person now and costs 7.65 percent in employer payroll tax. A retirement plan contribution delivers a deferred benefit, carries no payroll tax, and can often be weighted toward owners and key employees through plan design. Equipment requires you to spend real money on something the business needs and to have it placed in service before December 31.
The question underneath all three is what the business is trying to accomplish. Retention argues for the bonus or the vesting schedule in a retirement plan. Owner wealth outside the business argues for the plan contribution. Capacity argues for the equipment. Treating your business as your most important investment means picking based on what it builds, with the deduction as a tiebreaker rather than the reason.
There is also a wage interaction worth modeling at higher income levels, since W-2 wages figure into the limitation on the qualified business income deduction. More wages can raise that limit while simultaneously reducing the income the deduction applies to. It cuts both directions, and the only way to know which dominates is to run it.
This is a fictional example created to illustrate how Harness Advisory would advise a business owner in this situation. It is not a real client.
Mia owns a commercial interior design firm in Wisconsin with about $2.6 million in revenue and twelve employees, organized as an S corporation on the accrual method. A large project closed in September and profit is running roughly $300,000 ahead of last year. Her instinct is to pay herself a $120,000 bonus in December and give the team something as well.
Our advisory team would separate the two decisions, because only one of them is a tax strategy. The owner bonus would move $120,000 from distribution to wages, adding Medicare tax on the full amount and Social Security tax to the extent she is under the wage base, against income that flows through to her return either way. We would generally advise against it unless it serves a second purpose, such as supporting reasonable compensation or unlocking a larger retirement plan contribution.
The employee bonuses are a different conversation. Because the firm is on the accrual method, we would look at fixing a defined pool by December 31 with proper reallocation language, paying it in the first quarter, and taking the deduction this year while keeping the cash through the slow part of winter. That sequencing is often worth more than the bonus decision itself.
We would then compare the remaining profit against a profit sharing contribution, which carries no payroll tax and can be weighted through plan design, and against equipment the studio was already planning to buy. Finally we would rerun her Q4 estimate, since all of this changes the number.
Mia would end up rewarding her team, keeping the deduction in the higher year, and skipping the one move that felt the most like tax planning and would have cost her the most.
Harness Advisory is a national tax advisory and business advisory platform, and bonus timing is a good illustration of why that matters. Any CPA firm can record history, which here means reporting in March what you paid in December. As your tax advisory partner, we help you build a future, which means modeling the decision in October while the pool, the timing, and the recipients are all still adjustable.
Our advisory team looks at the bonus alongside your projection, your cash flow through the winter, your retirement plan design, and your estimated payments, because moving one of those moves the others. Clients tend to describe the relationship as closer to a board member than a bookkeeper, because the recommendation is often to reward people differently rather than simply to spend before year end.
It is a structured, educational conversation rather than a line-by-line review of your payroll. We look at where your year is landing, what you want to accomplish with the money, and which combination of bonus, plan contribution, and capital spending gets you there. You leave with a clear sequence and the deadlines attached to each piece. There is no obligation beyond the meeting.
| A bonus decision made in October can be structured. The same decision made on December 22 is mostly a payment. Schedule a consultation with Harness Advisory and we will model what your bonus plan actually costs, what it saves, and whether something else does the job better. |

Yes, a bonus reduces business income by the bonus amount plus the employer payroll tax on it. The timing of the deduction depends on your accounting method: cash-basis businesses deduct when the bonus is paid, while accrual-basis businesses may deduct a bonus accrued at year end if it is paid within two and a half months after the close of the year.
If you are on the cash method, yes, payment before year end is the only way to get the deduction this year. If you are on the accrual method, you may be able to fix the bonus pool by December 31 and pay it in the first quarter while still deducting it this year. That option requires the liability to be fixed, not discretionary.
Usually not for tax reasons alone. Moving money from distributions to wages adds Social Security tax up to the wage base and Medicare tax on the full amount, against income that already flows through to your return. An owner bonus makes sense when it supports reasonable compensation, enables a larger retirement plan contribution, or serves another documented purpose.
It allows an accrual-basis business to deduct compensation accrued at year end if the amount is paid within two and a half months after the close of the tax year. Miss that window and the bonus is treated as deferred compensation, deductible only when paid. The rule does not help with bonuses payable to owners, because the related party rules in Section 267 apply instead.
Fix the total bonus pool in writing before December 31 and include language reallocating any forfeited amounts among remaining employees rather than returning them to the company. Revenue Ruling 2011-29 addresses this directly. Discretionary bonuses and plans requiring continued employment at the payment date generally do not qualify.
In October, while the pool size, the timing, and the mix of bonus versus retirement contribution are all still adjustable. By late December the structuring options have narrowed to whatever you can execute through payroll. Harness Advisory works with business owners nationally on year-end compensation planning and the cash flow that follows it.
