Putting off a tax return can start with a simple thought: “I’ll take care of it when things settle down.”
Maybe you changed jobs, went through a divorce, had a medical emergency, or had a difficult year in business. Maybe you knew you owed taxes and didn’t have the money to pay them. After a while, opening an IRS envelope starts to feel like one more problem you aren’t ready to deal with.
I understand how that happens. But not filing a tax return doesn’t make the tax issue go away. And the longer a return remains unfiled, the harder it can become to understand what needs to be done.
The good news? You can take steps to address missing returns, even if you haven’t filed in several years.
1. The IRS may know about your income even if you don’t file
The IRS receives income information from employers, banks, and other sources. Depending on your circumstances, that information may include W-2 wages, interest, and other income reported on information returns.
If the IRS believes you were required to file but has no record of your return, it may send notices asking you to file or explain your situation.
Ignoring those notices can lead to further compliance activity. The important thing is to determine which tax years are missing, whether you were required to file, and what the IRS is asking you to do.
2. The IRS may prepare a Substitute for Return
One of the more serious consequences of not filing is that the IRS may prepare a Substitute for Return, commonly called an SFR.
Think of it as the IRS preparing a return based on the information it has available rather than the complete financial picture you would report on your own tax return.
For example, imagine you worked as an independent contractor and received several Forms 1099. You had business expenses for supplies, mileage, insurance, and other costs, but you never filed your return.
The IRS may have information about the income you received without having the information needed to account for all your eligible business expenses.
That can result in a proposed tax bill that doesn’t accurately reflect your situation.
An SFR is not necessarily the final word. Depending on the stage of the case, you may be able to file your own accurate return and correct the tax calculation. Pay close attention to any notice you receive because some notices have specific response deadlines.
3. Penalties and interest may increase what you owe
If you were required to file and had tax due, failing to file on time can result in a failure-to-file penalty. A separate failure-to-pay penalty may also apply, and interest can accrue on unpaid tax and certain penalties.
For many individual income tax returns, the failure-to-file penalty is generally calculated at 5% of the unpaid tax for each month or partial month the return is late, up to 25%. Specific rules and exceptions can affect the calculation.
This is one reason it’s worth addressing missing returns as soon as you reasonably can. The longer you wait, the more complicated the balance may become.
However, don’t assume that you owe a penalty simply because a return is missing. Your filing requirement, payments already made, potential refund, and individual circumstances all matter.
4. Not filing can lead to collection action
If the IRS assesses tax and the balance remains unpaid, the case may eventually move into collections.
Depending on the circumstances and the notices issued, collection activity can include a federal tax lien or a levy.
These are not the same thing.
A federal tax lien is a legal claim against your property and rights to property related to an unpaid tax debt. It can complicate certain property transactions and financing.
A levy is an action that allows the IRS to take property to satisfy a tax debt, subject to applicable legal requirements and procedures. Depending on the circumstances, that can include funds in a bank account or money from wages.
These actions do not automatically happen to every taxpayer who misses a return. But leaving filing requirements and IRS notices unresolved can increase the risk of additional problems.
If you receive a notice proposing an assessment or warning of collection action, read it carefully. The type of notice and the response deadline matter.
5. You may need to file more than one year
If you haven’t filed for several years, you may be wondering where to start.
The answer isn’t always to prepare every missing return in random order. First, you need to understand which years are missing, which returns are required, and what the IRS or California tax agency is requesting.
Depending on your situation, that may involve:
Identifying missing federal and California returns.
Gathering W-2s, Forms 1099, bank records, and business expense information.
Reviewing IRS and California Franchise Tax Board notices and account information.
Preparing accurate returns for the required years.
Determining how to address any balances due after the returns are filed.
The IRS may have specific compliance requirements for your case, so don’t assume the same number of years applies to every taxpayer.
If you live in California, remember that federal and state filing obligations are separate. Resolving your federal filing issue does not automatically resolve your California filing issue.
6. What if you couldn’t afford to pay?
This is a common reason people avoid filing. They know they may owe money, and they assume filing will make the situation worse.
But filing and paying are two different issues.
If you’re required to file, not having enough money to pay generally isn’t a reason to leave the return unfiled. Filing can help establish the correct tax amount and make it possible to evaluate your options.
Depending on your financial situation and the facts of your case, possible next steps may include a payment plan, penalty relief when you qualify, or another available tax resolution option.
An Offer in Compromise, for example, is not available to everyone. Eligibility depends on specific requirements and a review of your circumstances.
The first step is understanding what you actually owe and getting the required returns filed. From there, you can evaluate the options that may fit your situation.
7. How to start fixing unfiled tax returns
If you have one missing return or several, start by gathering the information you have and identifying the years involved.
You don’t have to know every answer before asking for help. A tax professional experienced in tax resolution can help you understand what the IRS is requesting, what returns need attention, and what steps may be available based on your circumstances.
The goal isn’t simply to file paperwork. It’s to get an accurate picture of your tax situation, address the missing returns, and determine how to handle any balance that remains.
