What Is Tax Liability?

What Does Tax Liability Work?

You can find your tax liability on lines 37 and 38 of the 2022 IRS Form 1040 when you've completed it. The IRS occasionally tweaks the Form 1040, but you'll find the information on these same lines on your 2021 return as well. The line numbers may change for tax year 2023, the return you'll file in 2024.

Appropriately, line 37 says, "Amount you owe.” Line 38 is dedicated to any penalty you might also owe for making your estimated tax payments late.

Technically, line 24 is your total liability for the tax year, but the IRS probably already has some of that money, either through tax withholding from your paychecks or because you've made quarterly estimated payments. It's line 37 that you have to concern yourself with because the IRS still wants that balance.         

Payments you've already made to the IRS appear on line 33. The difference between this and line 24 will either appear on line 34 as an overpayment, indicating that you'll be receiving a refund, or on line 37 as a balance you still owe.

Your employer likely deducted a percentage from your pay all year for taxes, based on the information you submitted on your Form W-4. They sent this money, your tax withholding, to the IRS on your behalf. The amount appears on line 25a of your 2022 tax return.

You might have made estimated tax payments during the year if you’re self-employed, or because you enjoyed some source of unexpected income from which taxes weren't withheld. These payments are made using Form 1040-ES, Estimated Tax for Individuals. The amount you paid should be entered on line 26 of your 2022 1040 tax return, the return filed in 2023.

All these payments are subtracted from the number that appears on line 24 to arrive at your tax liability.

You would receive a refund of $2,500 if your tax liability was $5,000, but the total of your payments and any refundable tax credits you qualified for was $7,500. You'd still owe the IRS $1,000 if your liability was $5,000 and you only made $4,000 in total payments, including tax credits.

An Example of Tax Liability

Income tax is the largest component of tax liability for most people. It’s determined in part by tax brackets, the percentage of each portion of your income that you must pay in taxes. These percentages vary depending on both your filing status and how much you earn.

You'd be in the 10% tax bracket in 2022 and your income tax liability would be $1,020 if you’re single and you were to earn just $10,200. You would be pushed up into a 24% tax bracket on the portion of your income that exceeds $89,075 if you were to earn $95,000.

Your tax liability isn't based on the total money you earn in a given year. It's based on your earnings minus the standard deduction for your filing status, or your itemized deductions if you decide to itemize instead. It's also based on any above-the-line adjustments to income or tax credits you might be eligible to claim.

The standard deduction has increased for single filers from $6,350 in 2017 to $12,950 in 2022. It, too, is indexed for inflation, and it increases to $13,850 in tax year 2023. Using the hypothetical $10,275 single taxpayer earnings for 2022, subtracting the $12,950 standard deduction for 2022 would leave a negative balance and zero tax liability.

You might also make certain adjustments to your total income on Schedule 1, "Additional Income and Adjustments to Income." These would be in addition to the standard deduction or itemized deductions you can also claim. They include things like educator expenses, the student loan interest deduction, and a portion of the self-employment tax you'd have to pay if you work for yourself.

Tax credits reduce your tax liability, too, but in a different way. Deductions subtract from your income so you're taxed on less money, but credits subtract directly from what you owe the IRS. Your liability would drop from $5,000 to $4,000 if you're eligible to claim a $1,000 tax credit, just as though you had written the IRS a check for that amount.

Types of Tax Liability

Tax liability isn’t limited to any income tax you might owe. Technically, the term covers all forms of taxes, such as capital gains and self-employment tax, as well as interest and penalties. Other contributing factors include:

• Interest that's added to your total tax liability if you entered into an installment agreement with the IRS to pay a previous year’s taxes.
• An early distribution from a retirement account that was subject to the 10% penalty.
• Capital gains tax if you sell an asset for more than your basis in it. Your basis is the amount of your investment in the asset. Long-term gains are taxed at special capital gains rates: 0%, 15%, or 20%, depending on your income (with some rare exceptions). It's a short-term gain if you owned the asset for one year or less. It would be added to your tax liability as ordinary income in this case and taxed according to your tax bracket.

How To Pay Off a Tax Liability

The bottom line is that you must pay the balance on line 37 of your tax return as quickly as possible to avoid paying interest and penalties on the amount until it's paid off.

The IRS offers online payment options via Direct Pay or the Electronic Federal Tax Payment System (EFTPS). You can also pay by debit or credit card, electronic funds withdrawal, bank wire, check or money order, or even with cash at certain retail partners.

The IRS offers installment agreements that will allow you to pay off your tax liability over time if you simply don't have the funds to do so right away. Interest will accrue, and there's a modest fee. But it's much better to pay over time than to ignore your debt and hope it goes away, because it won't.
