Deducting employee benefits: what your company can claim and when

If you are trying to work out which employee benefits your company can deduct, the honest answer is that the deduction is rarely the hard part. Almost everything you spend on employees is deductible as compensation. What varies is whether the benefit is taxable to the employee, and which tax year the deduction lands in.

Those two questions are where the money and the mistakes are. A benefit that is excluded from the employee's income costs you less than cash of the same value, because neither side pays payroll tax on it. A bonus accrued in December and paid in April may be deductible a year later than your books assume. Both of those change your numbers. The threshold question of deductibility usually does not.

Here is how the three questions separate, and which of them is worth your attention.

Almost everything you spend on employees is deductible

Wages, salaries, bonuses, commissions, health insurance premiums, retirement plan contributions, and the cost of most fringe benefits are ordinary and necessary business expenses. Your company deducts them.

The standard qualifications are real but rarely binding. Compensation has to be reasonable, which matters in closely held companies where an owner's salary is doing double duty, and much less anywhere else. The company has to actually be liable for the expense. That is most of the test.

One claim that circulates widely is worth correcting: there is no rule that a health plan must cover 70% of eligible employees for the premiums to be deductible. Participation thresholds like that come from insurance carriers underwriting small group plans, not from the tax code. Your company's premium deduction does not depend on them.

The question that matters is whether it is taxable to the employee

This is the distinction the deduction question hides. Your company deducts the cost either way. What changes is whether the employee pays income tax on it, whether both of you pay payroll tax, and whether it has to appear on a W-2.

Excluded from the employee's income. Employer-paid health, dental, and vision premiums. Employer contributions to a qualified retirement plan. HSA contributions. Group-term life insurance up to $50,000 of coverage. Educational assistance under a written Section 127 program. Dependent care assistance under a written plan. Qualified transportation fringes. Working condition fringes and de minimis items.

Taxable and reportable as wages. Cash and cash equivalents of any amount, which includes gift cards, so the $25 gift card is wages. Bonuses. Personal use of a company vehicle. Group-term life coverage above $50,000. Most reimbursements made outside an accountable plan. Moving expense reimbursements, where the exclusion is suspended.

The pattern is that cash is always taxable and specific statutory categories are not. There is no general exclusion for things that feel like perks, which is why gift cards and spot bonuses so often get handled wrongly.

Most of the excluded categories also come with nondiscrimination conditions. If a benefit is structured so that owners and highly compensated employees get it and the rest of the workforce does not, the exclusion can fail for exactly the people it was set up for.

Timing is where accrual-basis companies lose the deduction

If your company is on the accrual basis, the year you deduct a benefit is not always the year you booked it.

Bonuses and accrued compensation. An accrued bonus is generally deductible in the year of accrual only if it is paid within two and a half months after year end. Miss that window and the deduction moves to the year of payment. For a December year end, the date to watch is March 15.

Amounts owed to owners. Compensation accrued to an owner who reports on the cash basis is not deductible until it is actually paid, and the related-party rule overrides the two and a half month window. Accruing a bonus to a majority shareholder at year end does nothing for the current year unless the money moves.

Retirement plan contributions. These run the other way. An employer contribution made after year end can generally be deducted for the prior year if it is funded by the due date of the return including extensions, which is the one benefit where filing an extension buys you real optionality.

Benefits also touch three systems that have to agree: payroll, the books, and the return. Most of the errors we see are reconciliation failures rather than judgment calls, where payroll treated something as a nontaxable fringe and the books recorded it as an ordinary expense and nobody compared the two. Inkle runs managed payroll covering federal and state withholding, and handles bookkeeping alongside Form 1120 and Form 1065, so the three systems are reconciled as the year runs rather than compared once it is too late to fix.

Accountable plans change the tax treatment, not the deduction

Reimbursing employees for business expenses is deductible either way. Whether it becomes taxable wages depends on how the arrangement is built.

An accountable plan requires three things: a business connection for the expense, substantiation to the employer within a reasonable period, and the return of any excess advance. Meet all three and the reimbursement is excluded from the employee's income and carries no payroll tax.

Fail any of them and the whole arrangement is nonaccountable. A flat monthly phone or car allowance with no receipts and no true-up is wages, subject to withholding and payroll tax on both sides. The company still deducts it, as compensation rather than as an expense reimbursement, but the employee is worse off and the payroll cost is real.

The failure mode is almost always substantiation. A plan that is accountable on paper becomes nonaccountable when nobody collects the receipts.

Owner-employees are the exception to most of this

If you own the company, most of the benefit exclusions above do not work the way they do for your staff.

A shareholder owning more than 2% of an S corporation cannot receive tax-free fringe benefits. Health insurance premiums paid on their behalf are included in W-2 wages for income tax purposes, though not subject to Social Security and Medicare, and the shareholder may then be able to take the self-employed health insurance deduction personally. Partners in a partnership and sole proprietors are treated similarly, because they are not employees of the business for these purposes.

Retirement plans are the significant exception. Qualified plan contributions work for owner-employees on the same basis as everyone else, which is what makes them the most efficient benefit available to a closely held company.

Several of the numbers changed for this tax year

Guidance written even a year ago is likely to carry stale figures, and a few of them moved for 2026.

Dependent care assistance. The exclusion limit was raised above the long-standing $5,000 for tax years beginning after 2025. If your plan document names a dollar figure, it may need amending to use the higher amount.

Educational assistance. The Section 127 limit, long fixed at $5,250, is now subject to inflation indexing, and the treatment of employer student loan repayments under the same program was made permanent.

Moving expense reimbursements. The suspension of the exclusion was originally scheduled to end after 2025. It was made permanent, so these remain taxable wages with no sunset to wait for.

Contractor reporting. The long-standing $600 threshold for issuing a Form 1099 to a contractor was raised for payments made after 2025. If your process still flags every vendor at $600, it is now flagging more than it needs to.

The bottom line

Stop asking whether a benefit is deductible, because it almost always is, and start asking whether it is taxable to the employee and which year it lands in. Cash and cash equivalents are always wages, the statutory exclusions are a closed list with nondiscrimination strings attached, and accrued compensation has a payment deadline attached to your deduction. If you own more than 2% of an S corporation, assume the fringe benefit exclusions do not apply to you and that retirement contributions are the exception worth using. The version of this that costs real money is a benefit treated as nontaxable in payroll, deducted as an ordinary expense in the books, and never reconciled against either.

Frequently asked questions

Are employer-paid health insurance premiums deductible?

Yes, as an ordinary and necessary business expense, and they are generally excluded from the employee's income as well. There is no participation percentage in the tax code that has to be met for the deduction. Insurance carriers impose their own participation requirements for issuing a small group policy, which is a separate matter from deductibility.

Are employer 401(k) contributions subject to payroll taxes?

No. Employer contributions to a qualified retirement plan are excluded from the employee's wages for income tax, Social Security, and Medicare purposes. Employee elective deferrals work differently: they are excluded from income tax but remain subject to Social Security and Medicare.

When do I have to pay a bonus to deduct it in the year I accrued it?

An accrual-basis company generally has two and a half months after year end, so March 15 for a December year end. The exception is compensation owed to a related party who reports on the cash basis, including most owners, where the deduction waits until the amount is actually paid regardless of that window.

Can an owner of an S corporation receive tax-free benefits?

Not most of them. A shareholder holding more than 2% is treated like a partner rather than an employee for fringe benefit purposes, so health premiums and similar benefits are included in W-2 wages, though the shareholder may be able to deduct health insurance personally. Qualified retirement plan contributions are the main benefit that still works normally.

Are gift cards to employees deductible?

Yes, and they are also taxable wages. Cash equivalents never qualify as de minimis fringe benefits no matter how small the amount, so a gift card has to run through payroll with withholding. A non-cash item of minimal value, such as a holiday turkey or occasional refreshments, can qualify as de minimis.

What happens if we reimburse expenses without collecting receipts?

The arrangement is nonaccountable, which makes the reimbursements taxable wages subject to withholding and payroll tax for both the company and the employee. The company still deducts the amount, but as compensation. Substantiation within a reasonable period is what keeps a plan accountable, and it is the requirement that most often fails in practice.
