Tax payment important date depend on what kind of tax you owe

The due date for taxes is not one date — it changes based on whether you owe federal income tax, state income tax, self-employment tax, or property tax. Federal income tax returns are due April 15 each year (or the next business day if April 15 falls on a weekend). If you owe money when you file, that payment is also due by April 15. Self-employment tax and estimated quarterly taxes have their own separate important date throughout the year.

State income tax important date usually match the federal important date of April 15, but some states have different dates. Property tax important date vary widely by county and can fall anywhere from spring through winter depending on where you live. The key is finding out which taxes explore to you, then marking those specific dates on a calendar rather than assuming everything is due on April 15.

Key Takeaways

  • Federal income tax returns and payments are due April 15 each year, unless that date falls on a weekend or holiday.
  • If you are self-employed or have investment income, you owe estimated quarterly taxes on June 15, September 15, January 15, and April 15.
  • State income tax usually follows the federal April 15 important date, but check your state's revenue department website to confirm.
  • Property tax important date are set by your county or municipality and can fall in any season, so contact your local assessor's office for your specific date.
  • Paying late triggers penalties and interest charges that grow each month, so contacting the tax authority before the important date is better than paying after.

Federal income tax important date throughout the year

If you work as an employee and have taxes withheld from your paycheck, you file once a year by April 15. The IRS (Internal Revenue Service) collects your tax throughout the year through payroll withholding, so if your withholding is correct, you may owe nothing or receive a refund.

If you are self-employed, own a business, or have significant investment income, you owe estimated quarterly taxes — payments made four times a year instead of one lump sum on April 15. These are due on April 15, June 15, September 15, and January 15 of the following year. Missing even one quarterly payment triggers penalties, so if you are self-employed for the first time, contact a tax professional or the IRS to understand what you owe.

The IRS accepts payments through its website (IRS.gov), by phone, by mail, or through a bank. If you cannot pay by April 15, you can request a payment plan that lets you pay in installments over several months, though interest and penalties still accrue on the unpaid balance.

State income tax and when it is due

Most states that have an income tax use April 15 as the important date, matching the federal important date. However, a few states have different dates. Delaware's important date is April 30. Iowa's is April 30. Louisiana's is May 15. If you live in one of these states or moved during the year, check your state's revenue or taxation department website to confirm the exact date.

Some states do not have an income tax at all — these include Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming. If you live in one of these states, you only owe federal income tax, not state income tax. If you moved to one of these states partway through the year, you may owe state tax to your previous state for the months you lived there.

State tax payments are usually made through your state's revenue department website or by mail. Some states allow you to pay when you file your return; others require payment by a separate important date even if you file early.

Property tax important date and how they work

Property tax is different from income tax — it is based on the value of real estate you own, not on money you earned. The important date varies by county and municipality. Some areas bill property tax twice a year (spring and fall), others once a year. Your local assessor's office or tax collector sends you a bill with the due date printed on it.

Property tax is often paid to your county or city government directly, or through an escrow account if you have a mortgage. If your lender has a mortgage on your home, they usually collect property tax as part of your monthly payment and pay it on your behalf, so you do not handle the important date yourself. If you own property outright, you receive the bill directly and must pay by the date shown.

Paying property tax late results in penalties and, in some cases, a lien on your property or foreclosure proceedings. If you cannot pay by the important date, contact your tax collector's office when ready — many offer payment plans or hardship deferrals.

What happens if you miss a tax important date

Missing a tax important date triggers two separate charges: a failure-to-pay penalty and interest. The penalty is usually 0.5% of the unpaid tax per month, up to 25% total. Interest is calculated daily and compounds, meaning you pay interest on the interest. Both charges continue to grow each month you do not pay.

If you file your return late but pay by the important date, you avoid the failure-to-pay penalty, though you may owe a failure-to-file penalty if you file more than 60 days late. If you owe both penalties, the IRS typically waives one of them, but you still owe the other plus interest.

The IRS and state tax agencies have authority to garnish wages, seize bank accounts, or place a lien on property to collect unpaid taxes. However, they must follow specific legal steps before doing so, and you have the right to request a payment plan or appeal. If you cannot pay, contacting the tax authority before the important date is far better than ignoring the bill.

How to pay taxes on time

The IRS accepts payments through IRS.gov, by phone at 1-800-829-1040, by mail, or through an approved payment processor. You can pay with a debit card, credit card, or electronic bank transfer. If you pay by credit card, the card processor charges a fee (usually 1.87% to 2.35% of the payment), so paying by bank transfer or debit card is cheaper.

State tax payments are made through your state's revenue or taxation department website. Property tax is paid to your county or city tax collector, either online, by mail, or in person at their office. Some areas accept payment at banks or through third-party payment services.

If you cannot pay the full amount by the important date, you can request an installment agreement with the IRS or your state. The IRS offers short-term agreements (120 days or less) with no setup fee, and long-term agreements (more than 120 days) with a setup fee of $31 to $225 depending on how you pay. You still owe interest and penalties on the unpaid balance, but a payment plan stops additional failure-to-pay penalties from accruing.

Setting reminders so you do not miss a important date

Tax important date do not change year to year, so once you know your dates, you can mark them in a calendar or phone reminder. Federal income tax is always April 15. Estimated quarterly taxes are always April 15, June 15, September 15, and January 15. State important date are usually April 15 but vary by state. Property tax important date are set by your county and printed on your bill.

If you work with a tax professional or accountant, they often send reminders and handle payment on your behalf. If you file on your own, set a reminder at least one week before each important date so you have time to gather documents and make the payment. Many people set reminders on the 1st of the month before the important date is due, giving themselves two weeks to prepare.

Frequently Asked Questions

What if April 15 falls on a weekend or holiday?

The important date moves to the next business day. If April 15 is a Saturday, the important date becomes Monday, April 17. If it falls on a Sunday, the important date is Monday, April 16. The IRS announces the exact important date each year on its website.

Do I have to pay taxes if I did not earn much money?

It depends on how much you earned and what type of income it was. The IRS sets a threshold called the standard deduction — if your income is below that amount, you do not owe federal tax. However, you may still want to file to claim a refund of withheld taxes or tax credits. Check the IRS website or speak with a tax professional to know whether you must file.

Can I pay my taxes with a credit card?

Yes, but a payment processor charges a fee of roughly 1.87% to 2.35% of the amount you pay. For example, paying $1,000 in taxes costs an extra $19 to $24. Paying by bank transfer or debit card has no fee, so those methods are cheaper if you have the option.

What if I cannot pay my taxes by April 15?

Contact the IRS or your state tax agency before the important date to request a payment plan. The IRS offers installment agreements that let you pay over several months. You still owe interest and penalties on the unpaid balance, but a payment plan stops additional penalties from growing.

Are property taxes due on the same day as income tax?

No. Property tax important date are set by your county or municipality and can fall in any season. Your tax bill shows the due date. If you have a mortgage, your lender usually pays property tax from an escrow account as part of your monthly payment, so you do not manage the important date yourself.
