Mark Your Calendar: Essential Tax Deadlines You Can’t Miss in 2025!

It’s no surprise that tax year must have deadlines to fulfill tax administration requirements.

If taxpayers didn’t have a hard Tax Day to finish their income tax, it’s unclear if they’d be able to pay the tax for the financial year.

If someone works for an employer and receives a paycheck with taxes automatically deducted, they have already paid some taxes. However, in order to formally disclose their income, they must complete the appropriate tax forms. 

In some cases, they may even receive tax relief by getting some money back (and more) through credits and incentives.

When it comes to tax time, the dates could appear to be arbitrary, but they’re well-positioned to allow Americans an extra three months to review the tax year’s taxes and determine gross earnings to offset the tax deduction for business expenses as well as other taxable items.

Sometimes, tangible personal property could be included in the calculation, for instance, if the taxpayer has already paid their tax payments on property and then writes the tax off as income. No matter what the situation is, there are a good 13-15 weeks for gathering all necessary documentation and submitting the proper tax forms.

Keep deadlines short and extend them until the tax Preparations in 2025. Below are some deadlines to keep in mind:

Are State & Federal Tax Deadlines the Same?

But not always. If you reside within Alaska, Florida, Nevada, South Dakota, Texas, Washington or Wyoming, you do not have to pay state income taxes, which means you won’t have to file taxes on your income for your state.

If you are within New Hampshire or Tennessee, keep in mind that even though the state doesn’t pay taxes on wages but tax dividends and income. The general rule is that your state’s tax filing deadline is similar to the deadline for federal personal income tax. But, certain states have distinct deadlines for tax filing, including Delaware (May 1), Iowa (April 30), Louisiana (May 15) and Virginia (May 1).

Where Can I Check the State’s Tax Deadline?

The majority of times you can do a quick Google search by entering words such as “California state tax deadline” and at the top of the results, you will find your state’s tax-collecting agency.

These sites are also a great source for finding other credits for tax opportunities that apply for your tax returns from the state. Unfortunately, many state governments have websites that are not designed well and offer a bad user experience.

If you’re having difficulty finding the information you require on the website of your state, Sometimes you’ll get useful information from Google from blogs similar to this one. Simply look through the results to determine whether Google has embedded an informative fragment of the webpage that gives you the information you need.

What Happens If I Miss the Tax Deadline?

If you are unable to finish your taxes on time (and you are aware that this may be the case prior to the deadline) then you must extend your tax deadline using IRS form 4868.

If you don’t file the extension, you could be liable for tax penalties up to 25% of the tax bill.

Do not forget that you could need to submit a tax extension for your state and some states don’t allow the federal extension. The method for completing it differs in each state. Certain states require you to complete an online form.

Some require a paper application. There are also numbers you can call to request an extension by phone for some states.

Along with paying taxes on income taxes and other taxes, there are penalties and fines that you might have to pay. When your burden on tax falls below zero (meaning that you’ll receive an income tax refund) it is likely that you won’t get penalized.

However, if you owe taxes, don’t expect the IRS to act with clemency. The government has many programs that require cash flow and will be very careful to collect the money in time.

Remember that when you extend your taxes, and then fail to meet the deadline then you’ll be required to pay fines and penalties. A missed tax deadline can snowball into serious problems in the event that several years pass. The IRS could apply interest to penalties and fines. In some instances they can garnish your paycheck (removing some of it to pay off your debt) or freeze accounts at banks.

If you’re facing a situation such as this, it’s best to take the initiative and get in touch with the IRS or seek the assistance from a tax attorney who will represent you and identify ways to minimize the tax penalty.

Is it Possible File Taxes After the Deadline?

Yes,you can still file your tax after the deadline, and infact,you will need to. There are generally zero penalties when filing tax late in the event that you’re required to pay a tax refund.

If you notice that you’re always paying your federal and state tax returns after the deadlines for each It might be the right time to consider tax planning strategies that will assist you in staying ahead of the game and put more money in your pocket as well.

Be proactive in paying back taxes because aside from the snowballing effect of tardy payments, it can be extremely burdensome to calculate two years of tax (or more) at the same time.

When Should I Pay My Taxes?

Taxes are due on the deadlines listed previously, regardless of the date you make the filing. If you file online, it is possible to pay the payment on the spot generally with a debit card, checking account and credit card.

Be aware that if you make use of a credit card to pay taxes, you’ll likely be subject to additional charges from your bank. Therefore, it’s recommended to pay in cash, if you can. If you apply for an extension to your tax return however, you’ll still have to pay the taxes before the original due date. Extensions only give you extra time to file the return, not to pay.

In the event that you’ve estimated tax due to be paid, then you’ll be required to pay these quarterly according to the dates mentioned above.

For a bit more information: if you’ve established your business in the form of an S corporation, you will need to file a tax return and pay a portion of your taxes in a quarterly schedule unless you meet a certain requirement (such as not having a tax due from the previous year).

In the event that, by the end of the tax year the estimated tax amount is greater than the amount you actually have to pay , you will get a tax refund. If they’re not enough to pay off the tax debt and you are unable to pay, you must pay the extra.

Why do State and Federal Taxes Exist?

The federal tax system is used by the government to finance services such as the defense budget as well as the national government. The federal government includes various elements that range in scope from financial services (FINRA, SEC) to health and education.

State taxes are usually used to finance infrastructure projects (bridges roads, bridges railway systems, bridges) as well as higher education. If you’re curious about how your local government gets funded, like the police department, fire department department, local parks as well as K-12 schools, it’s typically done with property taxes.

A lot of ink has been poured on the legality of the Internal Revenue Service overseeing the activities of the previous calendar year and collecting personal GDP for the benefit of the government. What is right or wrong is beyond the scope of this article.

The only thing we can say is that tax administration is there and taxes must be paid. If you aren’t a fan of the idea of having to pay tax on your income, you’re absolutely free to move to a place that does not have a state income tax, for instance states like Texas or Florida. In recent years, certain states that have high personal income tax have seen the departure of people for states with lower taxes.

Although there are other aspects to consider, it is an important factor in many individuals to leave their home state to pursue lucrative opportunities elsewhere.
