Most people understand that receiving money can create taxable income.

Your employer pays you a salary.

You earn money from a business.

You receive interest from a bank.

You sell property at a gain.

But federal tax law contains a less intuitive rule:

You may receive taxable income even when somebody gives the money directly to the IRS instead of giving it to you.

In fact, the Treasury Regulations expressly address what happens when another person pays a taxpayer’s income tax.

The result can sound almost circular.

If another person pays your tax liability, the payment itself may constitute income to you—which means that additional tax may be attributable to the payment.

This principle is one reason employers sometimes use a technique known as a tax gross-up when they want an employee to receive a particular after-tax benefit.

Here is how the rule works.

Treasury Regulation § 1.61-14: Another Person Paying Your Taxes Can Be Income

Internal Revenue Code § 61 broadly defines gross income as “all income from whatever source derived” unless another provision of federal tax law provides an exclusion.

Treasury Regulation § 1.61-14(a) identifies several less obvious forms of gross income.

The regulation expressly states:

“Another person’s payment of the taxpayer’s income taxes constitutes gross income to the taxpayer unless excluded by law.”

That is remarkably broad language.

The regulation does not require the taxpayer to physically receive the money.

Instead, paying an obligation that belongs to the taxpayer can provide an economic benefit to that taxpayer.

Suppose, for example, that an employer owes an employee a $10,000 bonus.

Instead of simply paying the employee $10,000 and leaving the employee responsible for the resulting taxes, imagine that the employer agrees to pay the employee’s federal income tax associated with the compensation.

The employer’s payment of the employee’s personal tax obligation generally does not make the tax disappear from the employee’s economic picture.

The payment can itself represent additional compensation.

Treasury Regulation § 1.61-14 therefore illustrates a broader tax principle:

Income does not necessarily have to pass through your bank account to be income. (Legal Information Institute)

The Supreme Court Addressed This Almost 100 Years Ago

The principle has surprisingly old roots.

In Old Colony Trust Co. v. Commissioner, 279 U.S. 716 (1929), the Supreme Court considered an employer that had agreed to pay certain federal and state income taxes imposed on its officers.

The president of American Woolen Company, William M. Wood, received very substantial salary and commissions. The company then paid hundreds of thousands of dollars of federal income taxes attributable to his compensation.

The question was whether those tax payments constituted additional taxable income to Wood.

The Supreme Court said yes.

Its reasoning remains remarkably straightforward. The Court explained:

“The discharge by a third person of an obligation to him is equivalent to receipt by the person taxed.”

Because the employer paid Wood’s personal tax liability as consideration for his services, the payment constituted additional income to him.

The fact that Wood never personally received the tax money did not change the result. The money satisfied his obligation. (Legal Information Institute)

Why Paying Someone’s Bill Can Be Economically Similar to Giving Them Money

The rule becomes easier to understand if we temporarily forget about taxes.

Suppose your employer owes you a $5,000 bonus.

Instead of giving you $5,000, the employer pays $5,000 of your personal credit-card debt.

Economically, you are $5,000 better off.

The same basic reasoning explains why directing compensation toward a taxpayer’s personal liability generally does not prevent that compensation from being income.

The taxpayer has received an economic benefit because somebody else has discharged an obligation the taxpayer otherwise would have had to pay.

That concept becomes particularly interesting when the obligation being paid is the taxpayer’s tax itself.

Doesn’t This Create a Tax on a Tax?

Here is the entertaining part.

Suppose an employer promises:

“We will pay the income tax on your bonus.”

If the employer’s payment of the tax is itself additional taxable income, then isn’t there another tax attributable to the employer’s tax payment?

And if the employer pays that tax too, doesn’t the next payment create still more taxable income?

Mathematically, yes—that is precisely why gross-up calculations exist.

Interestingly, the taxpayer in Old Colony Trust raised essentially this concern.

The Supreme Court acknowledged the argument that treating the employer’s tax payment as income might result in a seemingly circular “tax upon a tax.” But the precise iterative calculation was not before the Court. The question presented was whether the employer’s payment of the employee’s income tax constituted additional taxable income.

The Court’s answer was unequivocal:

“The answer must be ‘Yes.’” (Legal Information Institute)

Modern payroll practices deal with this problem mathematically rather than pretending it does not exist.

What Is a Tax Gross-Up?

A gross-up is generally an additional payment intended to account for taxes imposed on another payment or benefit.

Suppose an employer wants an employee to receive a particular net amount after withholding.

Simply paying that amount plus the first layer of tax may not accomplish the goal because the additional amount used to cover the tax may itself constitute taxable wages.

The employer therefore calculates a larger gross payment designed to leave the employee with the desired net amount after applicable withholding.

This is not merely an informal accounting trick.

Treasury Regulation § 31.3402(g)-1 actually contains a regulatory example involving an employer that wants to provide an employee with a specified net bonus after withholding. The regulation describes the calculation as:

“grossing up the supplemental wage payment”

to determine the gross wages necessary to produce the intended net payment. (Legal Information Institute)

A Simplified Gross-Up Example

Imagine an employer wants an employee to receive exactly $1,000 after a hypothetical 20% tax, and assume for illustration that no other taxes or complications apply.

Paying the employee $1,200 would not quite work.

Twenty percent of $1,200 is $240, leaving only $960.

Instead, the calculation is:

Twenty percent of $1,250 is $250.

That leaves:

Thus, the employer would need a gross payment of $1,250 under those simplified assumptions to produce the desired $1,000 after-tax amount.

Real payroll calculations can be considerably more complicated because federal income-tax withholding, Social Security and Medicare taxes, state taxes, supplemental-wage rules, and other considerations may apply.

The IRS itself recognizes gross-up procedures in employment-tax administration. (IRS)

Employer-Paid Taxes Are Not Automatically Tax-Free Benefits

This rule is especially important when employers promise workers some form of “tax-free” compensation.

There is an enormous difference between:

a payment that federal law actually excludes from gross income

and

a taxable payment for which the employer agrees to cover some or all of the employee’s tax cost.

The second arrangement does not magically convert taxable compensation into tax-free compensation.

Instead, the employer may simply be providing more taxable compensation.

That additional compensation can then be structured so that the employee receives an intended amount after withholding.

Does the Rule Apply Only When an Employer Pays the Tax?

Treasury Regulation § 1.61-14 is not written exclusively in employer-employee terms.

It says:

“Another person’s payment of the taxpayer’s income taxes constitutes gross income to the taxpayer unless excluded by law.”

Accordingly, taxpayers should not assume that a tax liability disappears from federal income-tax consideration merely because another person writes the check.

The precise tax result, however, depends on why the payment was made and whether another Code provision applies.

For example, federal tax law contains exclusions for certain genuine gifts.

Treasury Regulation § 1.102-1(a) provides:

“Property received as a gift…is not includible in gross income”

subject to the limitations and distinctions contained in the tax law. (Legal Information Institute)

That means the surrounding facts and legal character of the transaction can matter enormously.

A company paying an employee’s taxes as compensation for services presents a very different tax situation from a family member making a bona fide gift.

Paying Someone’s Tax Does Not Necessarily Determine the Gift-Tax Consequences

Income tax and gift tax are also separate questions.

A payment that qualifies as a gift for income-tax purposes may avoid inclusion in the recipient’s gross income under IRC § 102, but the transfer may still implicate the federal gift-tax system for the person making the transfer.

That distinction frequently causes confusion.

“Not taxable income to the recipient” does not necessarily mean “irrelevant for federal tax purposes.”

The identity of the payer, the relationship between the parties, the reason for the payment, and the existence of compensation or other consideration can all affect the analysis.

The Broader Lesson: You Do Not Have to Receive Cash to Receive Income

Perhaps the most useful lesson from this strange rule has nothing specifically to do with tax gross-ups.

Federal income tax generally looks to the economic substance of what a taxpayer received, not merely whether cash physically entered the taxpayer’s hands.

A third party may pay an obligation for you.

An employer may provide a taxable fringe benefit.

Property may be received for services.

A liability may be satisfied on your behalf.

And in appropriate circumstances, those transactions can produce income even though the taxpayer never receives a traditional paycheck or cash deposit.

Treasury Regulation § 1.61-14 makes the point unusually clearly.

Someone else paying your income tax can itself constitute gross income.

The Bottom Line

Having another person pay your tax bill does not automatically make the payment tax-free.

Treasury Regulation § 1.61-14 expressly provides that another person’s payment of a taxpayer’s income taxes constitutes gross income unless federal law provides an exclusion.

And the rule is not merely theoretical.

Nearly a century ago, the Supreme Court held in Old Colony Trust Co. v. Commissioner that an employer’s payment of an employee’s income taxes as part of the employee’s compensation constituted additional taxable income.

That creates the seemingly strange possibility of tax being imposed because somebody paid your tax.

When an employer wants to absorb that additional tax burden and deliver a specified net benefit, the solution is generally not to ignore the additional income.

It is to gross up the payment.

Sometimes federal tax law really does require algebra. 😂
