If you’re reading this, you’re likely carrying the weight of unfiled tax returns and the anxiety that comes with it. Perhaps it started with one missed year during a difficult time, then snowballed into two, three, or even more years of returns you’ve avoided filing. You’re not alone. Millions of Americans have unfiled tax returns, and many live in constant fear of the consequences while paralyzed about how to fix the problem.

Here’s what you need to know: the situation is almost certainly not as hopeless as it feels. At the Law Office of Pietro Canestrelli, we’ve helped hundreds of California residents with multiple years of unfiled returns come back into compliance—often with better outcomes than they expected. As a former IRS agent, Pietro Canestrelli knows exactly how the IRS handles non-filer cases and what strategies produce the best results. This guide will explain your options, the realistic consequences you face, and the step-by-step process to resolve your situation.

Why People Stop Filing Tax Returns

Before diving into solutions, it’s important to understand that tax non-filing rarely reflects criminal intent or deliberate tax evasion. In our experience, clients stop filing for understandable reasons:

• Life disruptions: Divorce, death of a spouse, serious illness, or job loss can derail normal routines
• Overwhelming complexity: A new business, investment, or life change creates tax situations that feel unmanageable
• Fear of owing: Believing you’ll owe money you can’t pay leads to avoidance
• Lost records: Missing W-2s or other documents make filing seem impossible
• Simple procrastination: One missed year leads to embarrassment about the next, creating a cycle
• Mental health challenges: Depression, anxiety, and other conditions can make routine tasks feel insurmountable

Whatever brought you here, the path forward is the same: coming into compliance voluntarily almost always produces better outcomes than waiting for the IRS to find you.

What Happens When You Don’t File: The IRS Process

Understanding how the IRS handles non-filers helps explain why taking action now matters. Here’s the typical timeline:

Year 1-2: The Quiet Period

The IRS may not immediately notice a missing return, especially if you don’t have significant income reported on W-2s or 1099s. However, their matching systems eventually compare what they receive from employers, banks, and other payers against filed returns.

Year 2-3: Automated Notices Begin

Once the IRS identifies missing returns, they’ll send notices requesting that you file. These typically start as gentle reminders (CP59, CP516) and escalate over time. Many people ignore these letters, which is a mistake.

Year 3-4: Substitute for Return (SFR)

If you don’t respond, the IRS may prepare a “Substitute for Return” on your behalf. Here’s the critical point: the IRS-prepared return doesn’t include any deductions, credits, or favorable filing status you might be entitled to. They calculate the highest possible tax liability based on income reported to them.

For example, if you’re self-employed and should report $100,000 in income but had $60,000 in legitimate business expenses, the IRS SFR shows $100,000 in taxable income with no deductions—resulting in a vastly inflated tax bill.

Year 4+: Collection Activity

Once a tax assessment is made (whether you filed or the IRS created an SFR), collection begins. This can include:

• Tax liens filed against your property and credit
• Bank account levies
• Wage garnishment
• Passport denial or revocation
• Seizure of assets (in extreme cases)

The Penalties for Not Filing

The financial consequences of non-filing are significant and compound over time:

Failure-to-File Penalty

5% of unpaid taxes for each month the return is late, up to 25% maximum. This is the most severe routine penalty the IRS imposes.

Failure-to-Pay Penalty

0.5% of unpaid taxes for each month payment is late, up to 25% maximum. This runs concurrently with the failure-to-file penalty.

Interest

The IRS charges interest on unpaid taxes and penalties, currently over 8% annually and compounding daily. Unlike penalties, there’s no cap on interest.

Combined Impact Example

Consider a taxpayer who owes $10,000 and files 3 years late:

• Original tax: $10,000
• Failure-to-file penalty (capped at 25%): $2,500
• Failure-to-pay penalty (36 months × 0.5%): $1,800
• Interest (estimated at 8% compounded): $2,600
• Total owed: $16,900

That $10,000 liability nearly doubled due to penalties and interest—and it continues growing every day the situation remains unresolved.

Can You Go to Jail for Not Filing Taxes?

This is the question that keeps non-filers awake at night. The honest answer: it’s possible but extremely rare for simple non-filing.

Criminal prosecution for tax crimes typically requires the IRS to prove willful intent to defraud the government. Simple negligence, disorganization, or even fear-based avoidance generally doesn’t meet this standard. The IRS Criminal Investigation division focuses its limited resources on cases involving:

• Deliberate concealment of income
• Fraudulent schemes
• Large dollar amounts
• Patterns suggesting intentional tax evasion

Most non-filers face civil penalties, not criminal prosecution. That said, the longer you wait and the more income you fail to report, the higher the risk becomes. Coming forward voluntarily significantly reduces any criminal exposure.

The Surprise: You Might Be Owed Refunds

Here’s something many non-filers don’t realize: you may actually be owed money. We regularly see clients who avoided filing because they feared owing taxes, only to discover they had refunds waiting.

This happens when:

• Withholding from wages exceeded actual tax liability
• You qualified for refundable credits (EITC, Child Tax Credit) but didn’t file to claim them
• Estimated payments exceeded what you owed

Critical warning: You must file within three years of the original due date to claim a refund. If you had a refund coming for 2022 but haven’t filed, you have until April 15, 2026, to claim it. After that, the money is gone forever.

Step-by-Step: How to Come Back Into Compliance

Resolving unfiled returns requires a systematic approach:

Step 1: Determine How Many Years Need Filing

The IRS generally requires filing the last six years of returns to be considered compliant, though this can vary. Request your IRS account transcript to see what returns they show as filed or missing. Our team can obtain these transcripts on your behalf.

Step 2: Gather Income Information

Even if you’ve lost your records, you can reconstruct your income history:

• Wage and Income Transcripts: The IRS can provide records of all W-2s, 1099s, and other income reported for each year
• Bank statements: Review deposits to identify income sources
• Prior year returns: These provide context for ongoing income patterns
• Business records: If self-employed, gather what you can—even partial records help

Step 3: Reconstruct Deductions

This is where professional help becomes invaluable. We identify every legitimate deduction to minimize your tax liability:

• Itemized deductions vs. standard deduction for each year
• Self-employment deductions and business expenses
• Above-the-line deductions (student loan interest, HSA contributions, etc.)
• Tax credits you may have qualified for

Our guide on commonly overlooked tax deductions identifies opportunities many filers miss.

Step 4: Prepare and File Returns

Returns should be prepared carefully and filed strategically. In some cases, filing all returns simultaneously makes sense; in others, filing sequentially allows for better planning. The approach depends on your specific circumstances.

Step 5: Address the Resulting Tax Debt

Once returns are filed, you’ll know your actual liability. Options for resolving tax debt include:

• Full payment: If you can pay in full, this stops penalty and interest immediately
• Installment agreement: Monthly payments over time (up to 72 months for IRS, up to 60 months for FTB)
• Offer in Compromise: Settle for less than you owe if you qualify
• Currently Not Collectible status: Temporarily postpone collection if you have no ability to pay
• Penalty abatement: Request removal of penalties based on reasonable cause

California FTB: The State Tax Component

California non-filers face a double obligation—both federal returns (IRS) and state returns (Franchise Tax Board). The FTB follows similar procedures to the IRS but with some differences:

• California’s failure-to-file penalty is 5% per month up to 25%—identical to federal
• The FTB can assess a “Demand Penalty” of 25% if you don’t file after receiving a demand notice
• California can collect state tax debt without going to court (unlike most private creditors)
• The FTB actively shares information with the IRS

Any compliance strategy must address both federal and state obligations. Our team handles both simultaneously, ensuring nothing falls through the cracks.

Penalty Abatement: Reducing What You Owe

Once returns are filed, we can often reduce penalties significantly through abatement requests. The IRS offers several forms of relief:

First-Time Penalty Abatement

If you have a clean compliance history for the prior three years, you may qualify for automatic removal of failure-to-file and failure-to-pay penalties for one tax period.

Reasonable Cause Abatement

Penalties can be removed if you demonstrate reasonable cause for the failure to file. Qualifying circumstances include:

• Serious illness of you or immediate family member
• Death in the family
• Natural disaster
• Reliance on incorrect advice from a tax professional
• Inability to obtain records
• Other circumstances beyond your control

Our guide on requesting penalty abatement explains the process in detail.

When You Need a Tax Attorney

While some non-filers can resolve their situation independently, professional representation is essential in certain circumstances:

• Multiple years unfiled: The complexity increases dramatically with each additional year
• Substantial liability expected: If you’ll owe $10,000 or more, professional help typically saves more than it costs
• Self-employment or business income: Complex deductions and potential audit risk require expertise
• IRS has already contacted you: You need someone who can communicate effectively with the IRS
• Collection action has begun: Levies, liens, and garnishments require immediate professional response
• Criminal concerns: If there’s any possibility of criminal exposure, you need attorney-client privilege

Our article on why you need a tax attorney versus a tax preparer explains the important distinctions.

Real-World Success: How We’ve Helped Non-Filers

Without revealing confidential details, here are representative outcomes from our practice:

Self-Employed Contractor (5 Years Unfiled): Client believed he owed over $80,000 based on IRS notices. After filing proper returns with all legitimate business deductions, actual liability was $22,000. We negotiated an installment agreement and obtained penalty abatement, reducing total payments to $26,000 over 5 years.

W-2 Employee (4 Years Unfiled): Client avoided filing due to fear of owing. After reviewing wage and income transcripts, we discovered she was owed $12,400 in refunds—but one year was beyond the three-year refund deadline, resulting in $3,200 lost forever. This illustrates why acting quickly matters.

Small Business Owner (7 Years Unfiled): Client faced IRS Substitute for Return assessments totaling $340,000. By filing accurate returns and working through the appeals process, we reduced the liability to $67,000 and negotiated an Offer in Compromise settlement of $18,000.
