The “Federal Owed” figure on TaxAct is the federal income tax you still owe the IRS after the software subtracts your withholding, estimated payments, and refundable credits from your total tax for the year. It’s the same math the IRS uses on Form 1040: total tax minus total payments equals your balance due.1Internal Revenue Service. U.S. Individual Income Tax Return For the 2025 tax year, that balance is due by April 15, 2026, and you can pay it through TaxAct when you e-file or directly to the IRS.2Internal Revenue Service. When to File
The number covers federal income tax only. If your return also shows a state balance, TaxAct handles that separately, with its own payment options.3TaxAct. Tax Due Payment Methods (Federal Only)
Check the Number Before You Pay
Before sending money, confirm TaxAct’s figure. Pull out every W-2 and 1099 and match each income amount against what the software shows. A mistyped digit, especially an extra zero on investment income, can inflate a balance by thousands.
If you made quarterly estimated payments during the year, make sure each one is entered. You can cross-check what the IRS has on file through your IRS Online Account at irs.gov/account, which lists your payment history.4Internal Revenue Service. Estimated Taxes TaxAct’s “Forms” view shows the actual IRS forms line by line, which makes it easier to spot anything that looks off before you file.
When Your Federal Balance Is Due
The payment deadline for your 2025 federal balance is April 15, 2026. That deadline applies whether or not you file on time. A filing extension pushes your return deadline to October, but it does not extend the time to pay. If you expect to owe, estimate the amount and pay it by April 15 to avoid penalties and interest.5Internal Revenue Service. Taxpayers Should Know That an Extension to File Is Not an Extension to Pay Taxes
How to Pay the Balance
You have several ways to send the money. Some are free; some carry processing fees.
Electronic Funds Withdrawal Through TaxAct
When you e-file with TaxAct, you can authorize a direct debit from your checking or savings account as part of the filing process. Enter your routing and account number, then schedule the withdrawal for any date up to April 15. There’s no fee, and the option is only available to e-filers.6TaxAct. Pay Tax Owed – Tax Due Payment Methods (Federal)
IRS Direct Pay
IRS Direct Pay pulls funds from a checking or savings account through the IRS website. It’s free, requires no account, and gives instant confirmation. You can also schedule it for a later date if you want to file now and pay closer to the deadline.7Internal Revenue Service. Direct Pay With Bank Account
Credit or Debit Card
The IRS accepts card payments through approved third-party processors, each of which charges a convenience fee. For credit cards, the fee runs roughly 1.75% to 1.85% of the payment (minimum $2.50); commercial cards are higher. None of the fee goes to the IRS.8Internal Revenue Service. Pay Your Taxes by Debit or Credit Card or Digital Wallet
Check or Money Order
To pay by mail, print Form 1040-V from TaxAct and send it with a check or money order made out to “United States Treasury.” Write your Social Security number, daytime phone number, and “2025 Form 1040” on the check so the IRS credits the right account.9Internal Revenue Service. Form 1040-V Payment Voucher for Individuals
Whichever method you use, keep the confirmation number or a copy of the mailed check. If a payment ever gets lost or questioned, that record is your proof.
If You Can’t Pay the Full Amount
File your return on time even if you can’t pay. The failure-to-file penalty runs much steeper than the failure-to-pay penalty, and you can set up a payment arrangement afterward.
Short-Term Plan
A short-term plan gives you up to 180 days to pay in full. There’s no setup fee, and individuals can apply online if their combined tax, penalties, and interest come to less than $100,000. Penalties and interest keep accruing during the plan, so faster is cheaper.10Internal Revenue Service. Payment Plans; Installment Agreements
Long-Term Installment Agreement
For monthly payments over a longer period, setup fees depend on how you apply and how you pay:
- Direct debit from your bank: $22 online, or $107 by phone, mail, or in person.
- Other payment methods (Direct Pay, check, card): $69 online, or $178 by phone, mail, or in person.
- Low-income taxpayers: fee waived for direct debit; reduced to $43 for other methods.10Internal Revenue Service. Payment Plans; Installment Agreements
If your plan is approved and you filed on time, the monthly failure-to-pay penalty drops from 0.5% to 0.25%.11Internal Revenue Service. Failure to Pay Penalty
Offer in Compromise
If paying in full is not realistic even over time, an Offer in Compromise lets you settle for less than you owe. You must have filed all required returns, be outside any open bankruptcy, and be current on estimated payments. The application takes a $205 non-refundable fee plus an initial payment, and the IRS accepts an offer only when the amount reflects the most it could reasonably collect from your income, expenses, and assets.12Internal Revenue Service. Offer in Compromise
Late-Payment Penalties and Interest
Missing April 15 triggers two costs at once.
- Failure-to-pay penalty: 0.5% of the unpaid tax per month or partial month, capped at 25%.11Internal Revenue Service. Failure to Pay Penalty
- Failure-to-file penalty (if you also miss the filing deadline without an extension): 5% of the unpaid tax per month, capped at 25%. For returns filed more than 60 days late, the minimum is the lesser of $525 or 100% of the tax owed.13Internal Revenue Service. Collection Procedural Questions
- Interest on the unpaid balance, compounded daily: 7% per year for the first quarter of 2026, dropping to 6% for the second quarter (April through June 2026).14Internal Revenue Service.

Why You Ended Up Owing
Knowing the cause helps you decide whether to adjust withholding or start making estimated payments.
1099 Income With No Withholding
Freelance or contract work reported on Form 1099-NEC generally comes to you without any federal income tax or employment tax withheld.16Internal Revenue Service. What Businesses Need to Know About Reporting Nonemployee Compensation and Backup Withholding to the IRS You’re responsible for both the income tax and self-employment tax on that money, and without quarterly estimated payments the bill lands at filing time.17Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC
W-2 Withholding That Didn’t Keep Up
A regular paycheck can still leave you short if your Form W-4 doesn’t reflect your full picture. A side job, investment income, or a working spouse can push your combined income above what your employer’s withholding covers. The IRS Tax Withholding Estimator at irs.gov/W4App can tell you whether you’re on track, especially after a major life change.18Internal Revenue Service. Form W-4 (2026)
Capital Gains From Sales
Selling stocks, real estate, or other assets at a profit adds a capital gain to your taxable income. Long-term gains on assets held more than a year are taxed at 0%, 15%, or 20% depending on your total taxable income.19Internal Revenue Service. Topic No. 409, Capital Gains and Losses A large sale without matching estimated payments often creates a big balance due.
Life Changes
Losing Head of Household status, or having a child turn 17 and age out of the Child Tax Credit, raises your tax. The credit is worth up to $2,200 per qualifying child under 17, so losing it for even one child can flip a refund into a balance owed.20Internal Revenue Service. Child Tax Credit A raise into a higher bracket can do the same if your withholding hasn’t been updated.
Avoid Owing Next Year
You generally sidestep a balance due, and any underpayment penalty, if your withholding and estimated payments cover at least 90% of your current-year tax or 100% of your prior-year tax, whichever is smaller. You also avoid the penalty if you owe less than $1,000 after withholding and credits.4Internal Revenue Service. Estimated Taxes
For income that isn’t subject to withholding, such as freelance earnings, capital gains, or rental income, quarterly estimated payments through IRS Direct Pay or the Electronic Federal Tax Payment System keep you inside that safe harbor. If you’d rather handle it through your paycheck, use Step 4(a) of Form W-4 to have extra tax withheld for non-job income.18Internal Revenue Service. Form W-4 (2026)
