How to Pay Your Taxes: Methods, Timing, and What Happens If You're Late
Where and how you pay taxes depends on which tax you owe
Federal income tax, state income tax, property tax, and sales tax all move through different systems and go to different places. The IRS collects federal income tax. Your state revenue or tax department collects state income tax. Your county or local assessor's office collects property tax. Sales tax goes to your state, usually collected by the retailer at the register. Knowing which tax you owe and which agency receives it matters because each one has its own payment methods, deadlines, and consequences for late payment.
Most people pay federal and state income tax through payroll withholding—your employer deducts it from each paycheck and sends it to the IRS and your state. If you're self-employed, you pay quarterly estimated taxes. Property tax bills arrive once or twice a year from your county assessor, usually with a payment coupon or online portal. Sales tax is collected at the point of sale and you don't pay it separately. Understanding which system applies to you prevents missed deadlines and penalties.
Key Takeaways
- Federal income tax is paid to the IRS through payroll withholding, quarterly estimated payments if self-employed, or a lump sum when you file your return.
- State income tax goes to your state revenue department and is collected the same way as federal tax—through withholding, estimated payments, or when you file.
- Property tax is paid to your county assessor's office, usually twice a year, and the bill arrives by mail or through an online portal you can access.
- Paying late triggers penalties and interest that grow each month, and property tax arrears can lead to a tax lien or foreclosure after several years.
- If you cannot pay in full, the IRS and most states offer payment plans, and some counties allow property tax deferrals for seniors or low-income households.
Federal income tax payment methods and deadlines
If you're employed, your employer withholds federal income tax from your paycheck and sends it to the IRS on your behalf. You don't make a separate payment—the withholding happens automatically. The amount withheld depends on the W-4 form you filled out when you started the job. If too much is withheld, you get a refund when you file your return in April. If too little is withheld, you owe the difference when you file.
If you're self-employed or have income that isn't subject to withholding, you pay quarterly estimated taxes directly to the IRS. These are due April 15, June 15, September 15, and January 15 of the following year. You calculate the amount based on your expected annual income and pay it online through the IRS website, by mail, or through an electronic funds withdrawal from your bank account. If you miss a quarterly payment, you owe a penalty on top of the tax itself.
When you file your tax return, you either owe additional tax or receive a refund. If you owe, the deadline to pay is the same as the filing deadline—normally April 15. You can pay online through IRS.gov, by phone, by mail, or through an electronic funds withdrawal. The IRS also offers a payment plan (called an installment agreement) if you cannot pay the full amount at once. Short-term plans last up to 180 days with no setup fee. Long-term plans last several years and charge a setup fee of $31 to $225 depending on how you enroll.
State income tax payment methods and deadlines
State income tax works the same way as federal income tax. If you're employed, your employer withholds it from your paycheck. If you're self-employed, you pay quarterly estimated taxes. The deadline for quarterly payments and annual filing varies by state—some align with the federal April 15 deadline, while others differ. Check your state revenue department's website for the exact dates.
Payment methods also vary by state. Most states let you pay online through their revenue department website, by phone, by mail, or through automatic bank withdrawal. Some states charge a fee for online payments, usually 1 to 3 percent of the amount paid. If you owe state income tax and cannot pay in full, most states offer payment plans similar to the IRS—you can spread the payment over several months or years and pay interest and penalties on the unpaid balance.
If you move to a different state, you may owe income tax to both your old state and your new state for the year you moved, depending on how long you lived in each place and whether both states tax income. Some states have reciprocal agreements that prevent double taxation. Contact your old state's revenue department and your new state's revenue department to understand your obligations.
Property tax payment methods and deadlines
Property tax bills arrive from your county assessor's office, usually twice a year (spring and fall), though some counties bill once a year. The bill shows the assessed value of your property, the tax rate, and the amount due. It also lists the deadline for payment and any penalties for late payment. Most bills include a payment coupon you can mail with a check, or a website where you can pay online.
You can pay property tax by mail, online through your county assessor's website, in person at the assessor's office, or through automatic bank withdrawal if your county offers it. Some counties charge a fee for online payments. If you pay through your mortgage lender (as part of an escrow account), the lender collects the money from you each month and pays the county on your behalf. In that case, you don't make separate property tax payments—the lender handles it.
Property tax deadlines vary by county. Missing the deadline triggers a penalty, usually 5 to 10 percent of the unpaid tax, plus interest that accrues monthly. If property tax remains unpaid for several years (the exact number varies by state), the county can place a tax lien on your property, meaning the county has a legal claim against it. If the lien is not paid, the county can eventually foreclose and sell the property to recover the debt. Some counties offer payment plans or tax deferrals for seniors or low-income households—contact your assessor's office to ask.
What happens when you pay late
Late payment triggers penalties and interest that compound over time. For federal income tax, the failure-to-pay penalty is 0.5 percent of the unpaid tax per month, up to 25 percent total. Interest accrues daily at a rate set quarterly by the IRS (currently around 8 percent annually, but it changes). State income tax penalties and interest rates vary by state but follow a similar pattern. Property tax penalties are usually higher—often 5 to 10 percent of the unpaid amount—because counties want to discourage delinquency.
If you owe federal income tax and don't pay, the IRS can place a tax lien on your property, garnish your wages, or seize your bank account. These actions happen after repeated notices and usually only if you ignore payment demands. If you owe state income tax, your state can do the same. If you owe property tax, your county can foreclose on your home after the debt sits unpaid for a set number of years (usually three to five, depending on the state).
The key is to act before the debt grows. If you receive a tax bill and cannot pay in full, contact the tax agency immediately. Do not ignore the bill. The IRS, your state, and your county all offer payment plans and, in some cases, temporary relief if you're facing financial hardship. Responding early gives you more options than waiting until a lien is placed or a wage garnishment begins.
Payment plans and hardship relief options
The IRS offers short-term payment plans (up to 180 days) at no cost, and long-term installment agreements that last three to six years. Setup fees range from $31 to $225 depending on whether you enroll online or by phone. You can request a plan by calling the IRS, visiting IRS.gov, or filing Form 9465 with your tax return. The IRS will work with you to set a monthly payment amount based on what you can afford.
Most states offer similar installment plans for state income tax. Contact your state revenue department to ask about the process and any fees involved. For property tax, contact your county assessor's office. Some counties allow you to spread payments over several months, while others require full payment by the deadline. A few states and counties offer property tax deferrals for seniors or low-income households—you defer payment until you sell the home or pass away, at which point the deferred amount is paid from the sale proceeds or your estate.
If you're facing severe financial hardship, the IRS can place your account in currently not collectible status, which temporarily pauses collection efforts while you stabilize your finances. Interest and penalties continue to accrue, but the IRS won't garnish your wages or seize your bank account. You must reapply periodically to maintain this status. Contact the IRS at 1-800-829-1040 to discuss your situation.
How to track what you owe and when it's due
For federal income tax, create a calendar reminder for April 15 (or the next business day if April 15 falls on a weekend). If you're self-employed, add reminders for the quarterly estimated tax deadlines: April 15, June 15, September 15, and January 15. You can also enroll in the IRS's email notification service to receive reminders when deadlines approach.
For state income tax, check your state revenue department's website for the filing and payment deadlines specific to your state. Many states align with the federal April 15 deadline, but not all. Set a calendar reminder for your state's deadline and any quarterly payment dates if you're self-employed.
For property tax, your county assessor's office mails bills to your address on file. If you move, update your address with the assessor so you don't miss a bill. You can also check your property tax balance online through your county's website—most counties maintain a searchable database of property owners and their tax status. If you pay through a mortgage lender's escrow account, the lender handles the tracking and payment, but you can still check your county's database to confirm the payment was made.
Frequently Asked Questions
Can I pay my taxes with a credit card?
The IRS accepts credit card payments through approved payment processors, but they charge a convenience fee of 1.87 to 2.35 percent of the amount paid. Most states accept credit card payments for state income tax, also with a fee. Property tax payments by credit card vary by county—some accept them, others don't. Check your county assessor's website or call to ask. Paying with a credit card can make sense if you're earning rewards, but the fee eats into the benefit.
What if I can't pay by the deadline?
Contact the tax agency before the deadline, not after. The IRS, your state, and your county all prefer to work out a payment plan rather than pursue collection. Explain your situation and ask about installment plans or hardship relief. Ignoring a bill makes the problem worse—penalties and interest grow, and collection actions become more aggressive.
Do I have to pay property tax if I own my home outright?
Yes. Property tax is owed by anyone who owns real property, whether the property is paid off or financed. If you have a mortgage, your lender usually requires you to pay property tax through an escrow account as part of your monthly payment. If you own the home outright, you pay the county directly.
Can the IRS take my refund if I owe back taxes?
Yes. If you owe federal income tax from a prior year and file a return for the current year, the IRS can keep your refund and apply it to the back taxes owed. The same applies to state income tax—your state can intercept your state refund. This is called offset. If you know you owe back taxes, you can still file your current return, but expect the refund to be applied to the debt.
How long does the IRS take to process a payment?
Online payments are usually processed within one business day. Payments by phone or electronic funds withdrawal take one to three business days. Payments by mail take two to three weeks. If you're close to a deadline, pay online or by phone to ensure the payment is received on time. The IRS considers a payment made on the date it receives it, not the date you send it.
