Every year like clockwork you conscientiously pay your state income taxes, but this year you spaced and missed the deadline. Don’t panic. Forgetting to file state taxes is more common than you might think. The good news is that there are steps you can take to fix the situation and minimize any financial impact. If you’ve missed your state tax filing deadline, acting quickly can help reduce penalties and prevent escalating consequences. Here’s what you need to know and how to resolve the issue as efficiently as possible.
Are You Sure You Need to File?
As of 2025, if you live and work in any of the following states, you are not required to file an income tax return or pay state income taxes: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, and Wyoming. New Hampshire exempts wage earners from paying state income taxes, although interest and dividend income is taxed. In addition, Washington taxes capital gains income of high-earning individuals.
If you live or work in any of the other 41 states or in the District of Columbia, you still may not need to file a return. State tax laws generally require you to file a return if your income exceeds a certain threshold. These thresholds differ from state to state and may depend on your filing status, age, and residency status. If you worked in multiple states or had part-year residency, you may have filing requirements in more than one state. It’s crucial to note that if you do not file a return and are required to, you may be subject to late filing fees, late payment fees or both.
How to Get a State Tax Extension
If you need more time to file your state taxes, some states allow you to request an extension. Your state’s official website is likely to have information available on filing state tax returns after the deadline. If you cannot find the information online, contact your state’s treasury or tax office by telephone. Be prepared to answer general questions about your income and filing status, because your answers may have a bearing on whether you must file. For instance, many states exempt taxpayers who owe no state taxes from the requirement of filing a return. However, you will forfeit any refund or tax credits you might otherwise have received if you do not file a return.
Were You Granted an Automatic Extension?
Some states grant taxpayers an automatic extension of time to file if they filed an extension request with the IRS on or before the tax deadline. Other states require a separate extension request even if you filed a federal request. Again, consult your state’s official website or place a telephone call to the appropriate agency to obtain the information that you need.
What Do I Do Now If I Forgot to File State Taxes?
File your state taxes as soon as possible. The longer you wait to file your state taxes, the more penalties and interest you may incur. Therefore, it’s crucial to file your late return as soon as possible. Tax penalties imposed by the state can often rival those of the IRS, including liens and levies against your paycheck and assets or even possible jail time. The sooner you file, the quicker you can stop the clock on penalties and interest charges.
If you are missing Form W-2 or other tax records that you need to file a return, you can often obtain the information you need immediately through the IRS website. In some cases, you may need to make a request by telephone or regular mail, which will require extra processing time.
Understand the Penalties and Interest
States impose penalties and interest on late tax filings, and these costs increase the longer you wait. The specific penalties vary by state, but most include a late filing penalty, a late payment penalty, and interest charges on unpaid tax balances.
Late Filing Penalties
Many states impose a penalty for failing to file on time, usually calculated as a percentage of the unpaid tax. For instance, California charges a penalty of 5% of the unpaid tax per month, up to a maximum of 25%. In New York, the late filing penalty is 5% per month, capped at 25%, plus additional penalties if the return is more than 60 days late.
Late Payment Penalties and Interest
If you owe state taxes and fail to pay by the deadline, a separate penalty applies. This is usually lower than the late filing penalty but still accumulates over time. States typically charge 0.5% to 1% of the unpaid balance per month, with a cap of 25%.
Interest also accrues on unpaid taxes from the original due date until the balance is paid. States use different interest rates, which may be adjusted periodically. For example, California’s interest rate on unpaid taxes is currently 10% annually.
State Tax Amnesty Programs
Like the IRS, many states have adopted a cooperative attitude toward taxpayers who make honest mistakes. Some states have tax amnesty programs or otherwise eliminate or minimize penalties for taxpayers who owe and voluntarily come forward. If you just forgot to file, or didn’t file because you didn’t have the money, come clean with the proper authorities. Often, the state will work with you to develop a payment schedule that you can live with to bring you back into compliance. In some cases, you may be eligible for waivers or abatements of penalties and interest for late filing. This is more likely if you have a valid reason for filing late, such as a medical emergency or natural disaster. Contact your state’s tax agency to inquire about any available relief programs and how to apply for them.
Pay Any Taxes Owed
Once you’ve filed your late return, the next step is paying any taxes owed. If you can afford to pay the full amount, doing so will prevent further penalties and interest from accruing. However, if paying in full isn’t possible, most states offer payment plan options.
Setting Up a Payment Plan
Many state tax agencies allow taxpayers to request an installment agreement to pay their balance over time. These plans usually require a minimum monthly payment and may include additional fees. States have different eligibility requirements, but most require taxpayers to be up to date with their filings before a payment plan is approved.
For example, California’s Franchise Tax Board offers payment plans for balances under $25,000, allowing taxpayers up to five years to pay. New York allows installment agreements but may require financial disclosure if the amount owed is significant.
Requesting Penalty Relief
If you have a legitimate reason for missing your state tax deadline, you may be able to request penalty abatement. Many states offer penalty relief for first-time offenders or taxpayers who can demonstrate reasonable cause.
Reasonable Cause for Penalty Abatement
States define “reasonable cause” differently, but common examples include:
- A serious illness or hospitalization that prevented you from filing
- Natural disasters or emergencies that disrupted your ability to file on time
- Reliance on incorrect tax advice from a professional or the state tax agency
To request penalty relief, contact your state’s tax authority and explain your situation. Some states have formal penalty abatement request forms, while others allow taxpayers to submit a written statement.
Preventing Future Late Filings
To avoid missing future state tax deadlines, consider implementing a few proactive measures. Mark important tax deadlines on your calendar, set reminders, and use tax preparation software that alerts you about upcoming due dates. If you frequently forget to file, working with a tax professional or setting up automatic filing options can help.
