My name is Philip Falco. I am a tax attorney and a licensed CPA practicing in downtown Denver. I have been handling unfiled return cases since 1997. The dual credential is not just a differentiator on paper — it is directly relevant to this problem. You need someone who can prepare the returns accurately (CPA) and protect you throughout the process with attorney-client privilege (attorney). When those two functions are in the same person, nothing falls through the gap between them.
What you do next, and who you do it with, matters enormously.

CPA or Tax Attorney for Unfiled Tax Returns?
Attorney Client Privilege with CPA Preparation
The willful failure to file a Unites States Tax Return is a misdemeanor. Individuals with unfiled tax returns often begin seeking help by contacting their accountant. Federal and state laws recognize a limited accountant-client privilege concerning confidential communications. However, the privilege or confidentiality rules involving discussions between a client and their accountant do not extend to criminal cases.
Only the attorney-client privilege survives a state or federal criminal tax investigation or prosecution. This privilege is often a critical component in representing and defending a taxpayer with unfiled returns or unpaid (back taxes). If you have unfiled tax returns and need help, contact us.
Quite simply, unfiled tax returns are a crime. As a Dual Licensed CPA and Attorney, we provide the perfect match for this problem. First, as an attorney, you obtain the Attorney – Client Privilege. As a CPA, we prepare and file your past tax returns precisely. Our service is unmatched. We have years of experience on this exact issue.
The greatest fear of most taxpayers who have not filed tax returns is the prospect of “tax evasion.” The fact is that non-filing may result in criminal prosecution. A taxpayer must have had criminal intent to defraud the government to be prosecuted for tax evasion as opposed to just negligence, procrastination, stupidity, etc. Non-filing is a misdemeanor. The primary objective of the IRS is to bring delinquent taxpayers into compliance and back into the tax system. However, if you have not filed tax returns for more than six years (or four quarters of payroll tax returns), you may want to contact a professional knowledgeable in tax delinquency for advice. Most CPAs and Enrolled Agents, although knowledgeable in tax return preparation, are NOT experienced in handling significant tax delinquency matters. As a tax attorney and CPA, I handle the most difficult of unfiled situations.
Many taxpayers that have not filed for several years, and have lost their records, think they cannot file their tax returns and claim their deductions and business expenses because they do not have their records. There is no law that says you cannot file a tax return to report income and claim deductible expenses just because you do not have W-2’, 1099’s, receipts, cancelled checks, etc.
How to File Unfiled Tax Returns When You Don’t Have Your Records
One of the most common reasons people delay filing is the belief that they cannot prepare accurate returns without their original records — W-2s, 1099s, receipts, bank statements. Years pass, records are lost, and the problem compounds.
There is no legal requirement to have original source documents to file a tax return. The IRS maintains records of income reported to it by third parties — employers, financial institutions, clients — and those records are available through a Wage and Income Transcript. I obtain these transcripts directly from the IRS using a Power of Attorney (Form 2848), typically covering all years for which the IRS received reporting.
For business income and expenses where no third-party records exist, there are reconstruction methodologies that allow for a reasonable estimate of deductible expenses — bank deposits analysis, industry averages, affidavits from clients or vendors, and other evidentiary approaches that the IRS recognizes. The goal is an accurate return that reflects actual economic activity, even without pristine documentation.

What Are My Options for Dealing With Unfiled Tax Returns?
As to what years you should file, ask me. I can tell you I my many years of experience what years to file and how quickly. Your options are – file every return, file some returns, or file no returns. Filing returns does provide a continuous track records especially if you have assets, your executor would appreciate a record of filing. In addition, filing returns starts the clock ticking as to the Statute of Limitations,
The preparation of prior years of tax returns typically require enormous work, preparation, and care. The delay of tax return preparation has serious consequences if left unchecked. It is important to seize the moment as you read this and contact us (303) 626-7000.
If you have unfiled tax returns — one year or ten — you are not alone, and the situation is more manageable than it probably feels right now. The IRS’s primary objective with non-filers is compliance, not punishment. The vast majority of taxpayers who come forward voluntarily, file their delinquent returns, and address the resulting balance are treated as compliance matters, not criminal ones.
If you have received IRS Letter 1058, IRS Letter 729, IRS Form 12153, or CP 59 call us right away.
We have observed over the years that the delay of filing tax returns becomes habitual then deep fear takes hold further paralyzing the taxpayer. We have observed many taxpayers tackle this problem. Taxpayers who overcome this problem are empowered and become even more productive.
It has been our experience that many taxpayers with unfiled tax returns were or are self employed. Overwhelmed by the demands of small business, the taxpayer delays tax compliance. Years pass, and an enormous tax problem has mounted. A mountain of unfiled taxes consisting of several years piles up fast with a potentially large liability for back taxes.
The most common unfiled tax return is the 1040 tax return. Unfiled S Corporation returns, tax form 1120s, and partnership returns, tax form 1065, carry steep penalties. If you have unpaid taxes click this text to go to the unpaid taxes page.

If you have many years of unfiled tax returns it is important to set in place a solid strategy to handle the matter. Your strategy may involve Voluntary Disclosure. Voluntary Disclosure minimizes taxpayer exposure to criminal prosecution.
Having many years of unfiled returns does not, by itself, mean that a formal IRS voluntary disclosure is required.Many taxpayers can come back into compliance through ordinary delinquent-return filing procedures. The appropriate strategy depends on the number of missing years, available records, IRS activity, tax owed, and—most importantly—whether the failure to file may have been willful.
When the facts involve deliberate concealment of income, false returns, offshore assets, or other circumstances suggesting willful tax noncompliance, the IRS Criminal Investigation Voluntary Disclosure Practice should be evaluated before delinquent returns are filed. See our IRS Voluntary Disclosure Practice page.
The taxpayer, among other things, must file tax returns for appropriate years and be truthful in the filings.
We specialize in Voluntary Disclosure.
Unfiled Tax Returns Statutes of limitations
Criminal. 6 years. Charges can be brought within 6 years of a tax return’s due date.
Civil. The statute of limitations does not run on unfiled tax returns as far as civil liability. The statute of limitations does not begin to run on Unfiled tax returns.
IRS Notices.
It is best to prepare and file your delinquent returns before the IRS requests them. If the IRS has sent you notices requesting delinquent returns it is important to assess the matter with a competent tax professional.
Why Unfiled Returns Are a Legal Problem, Not Just a Financial One
Failure to file a required federal tax return is a federal misdemeanor under IRC § 7203, carrying potential penalties of up to one year in prison and fines up to $25,000 per year. That is the statutory framework. The practical reality is more nuanced.
Criminal prosecution for non-filing requires proof of **willful** failure — that you knew you were required to file and intentionally did not. Negligence, procrastination, financial overwhelm, poor recordkeeping, or plain avoidance of a problem you hoped would go away does not meet the legal standard for willfulness in most circumstances. The IRS reserves criminal referrals for cases involving fraud, deliberate concealment, or extended patterns of conduct with aggravating factors.
That said, the risk is not zero, and it increases with time. The criminal statute of limitations for failure to file is **six years** from the return’s due date. The civil liability on an unfiled return has **no statute of limitations** — the IRS can assess civil liability at any time, indefinitely, for years that were never filed.
The practical implication: if you have returns that are approaching the six-year mark, or if there are any facts in your situation that could be characterized as intentional, you want an attorney handling this — not an accountant.
Attorney-Client Privilege — Why It Matters for Unfiled Returns
When you hire a CPA or enrolled agent to handle your unfiled returns, the conversations you have with them are not fully protected. Federal law recognizes a limited accountant-client privilege, but it does not extend to criminal investigations or criminal proceedings. If the IRS refers your matter for criminal investigation — or if a grand jury issues a subpoena — your accountant can be compelled to testify about your communications.
Attorney-client privilege is different. Communications between you and your attorney, made for the purpose of obtaining legal advice, are protected in criminal proceedings. That protection does not disappear if the matter escalates.
When I represent a client with unfiled returns, every communication — your explanation of why returns were not filed, the financial details you share with me, your instructions about how to proceed — is covered by attorney-client privilege from the first conversation. I prepare the returns myself as a CPA, so there is no moment where the privileged engagement hands off to an unprotected one. That seamless protection is the specific advantage of working with someone who holds both licenses.
What the IRS Does When Returns Are Not Filed
If you have not filed and the IRS has information suggesting you had income — W-2s, 1099s, bank records — it does not simply wait. The IRS will prepare what is called a **Substitute for Return (SFR)** on your behalf.
An SFR is not a neutral document. The IRS prepares it using the income information it has and applies the most unfavorable filing status and deductions available — typically single or married filing separately, with no deductions beyond the standard deduction. Business expenses, itemized deductions, dependents, credits, retirement contributions, and other items that would reduce your tax liability are ignored entirely. The resulting assessment is almost always far higher than what a correctly prepared return would show.
An SFR is a legal debt. The IRS can collect on it immediately — through liens, levies, and wage garnishments — once it has been assessed and a statutory notice of deficiency has been issued and ignored. However, SFR assessments can be corrected. Filing the actual return for that year supersedes the SFR and replaces it with the correct liability. This is often one of the most impactful steps in a non-filer case: replacing an inflated SFR with an accurate return immediately reduces the debt, sometimes dramatically.
If the IRS agent says that you owe taxes for years that you know you have not filed, the IRS has probably made estimated tax assessments against you. The IRS calls these estimated assessments Substitutes for Returns or SFRs. These are legal debts and collectible by the IRS, but they can be corrected.
In relation to the SFRs, these assessments/liabilities are rarely accurate and, as previously stated, can be corrected.
How Many Years of Unfiled Tax Returns Do I Need to File? — The IRS Six-Year Compliance Policy
A common question from taxpayers with many years of unfiled returns is how far back they have to go. The IRS has an administrative policy — not a statute, but a consistent practice — of requiring **six years of delinquent returns** to establish compliance. If you have fifteen unfiled years, the IRS will typically accept six years of back returns and consider you in compliance, provided those six are accurate and complete.
This policy does not apply in every situation. If there are SFRs already on file for specific years, those years need to be addressed regardless of how long ago they were. If the IRS has specifically requested returns for particular years, those requests must be responded to. And if there are criminal exposure concerns, the strategy changes significantly.
Missing Records Are Not a Barrier to Filing
One of the most common reasons people delay filing is the belief that they cannot prepare accurate returns without their original records — W-2s, 1099s, receipts, bank statements. Years pass, records are lost, and the problem compounds.
There is no legal requirement to have original source documents to file a tax return. The IRS maintains records of income reported to it by third parties — employers, financial institutions, clients — and those records are available through a Wage and Income Transcript. I obtain these transcripts directly from the IRS using a Power of Attorney (Form 2848), typically covering all years for which the IRS received reporting.
For business income and expenses where no third-party records exist, there are reconstruction methodologies that allow for a reasonable estimate of deductible expenses — bank deposits analysis, industry averages, affidavits from clients or vendors, and other evidentiary approaches that the IRS recognizes. The goal is an accurate return that reflects actual economic activity, even without pristine documentation.
Unfiled Payroll Tax Returns — A Separate Category of Urgency
If your unfiled returns include **Form 941 quarterly payroll tax returns**, the situation carries additional risk that deserves specific attention.
The IRS treats payroll taxes differently from income taxes. Payroll taxes — the amounts withheld from employee paychecks for federal income tax, Social Security, and Medicare — are considered trust fund money. They belong to the employees and the government, not the business. The IRS pursues payroll tax delinquency aggressively and without the patience it sometimes extends to income tax non-filers.
Beyond the business liability, the IRS can assess a **Trust Fund Recovery Penalty (TFRP)** personally against any individual in the business who was responsible for collecting, accounting for, and paying over payroll taxes and willfully failed to do so. The TFRP equals 100% of the unpaid trust fund portion — which means corporate or LLC liability protection does not shield the responsible individuals from personal liability for the same debt.
Additionally, **Form 940** — the Federal Unemployment Tax return — carries a specific trap for non-filers: the federal unemployment tax is offset by state unemployment taxes paid, but only when the 940 is filed timely. If the 940 is filed late, the employer must prove state unemployment tax was paid through a certification process. Without that proof, the federal unemployment tax increases approximately twenty-fold. By the time most people discover this, the liability has already been assessed.
941 – Payroll Taxes. If your unfiled tax returns are Quarterly Payroll Tax returns, Form 941, for employee wages, the IRS also has the authority to prepare and assess payroll tax liabilities in the same manner as substitute tax returns. In this situation the IRS uses previously filed Forms 941 to estimate wages paid and resulting payroll taxes. The IRS can also do this as the result of a personal audit if they determine that you intentionally misclassified workers as independent contractors instead of as employees, and did not withhold taxes from paychecks.
Payroll taxes are considered by the IRS to be the most serious taxes that they collect and are aggressively pursued. If you have not paid payroll taxes for more than one quarter, cannot pay them within 90 days and are currently incurring additional payroll tax liabilities, you have a serious cash flow problem and need to take immediate corrective action.
You must realize that payroll tax funds do not belong to the business. They are your employees’ money and the IRS moves aggressively to collect those funds. In fact, if you are a corporation, the IRS can pierce the corporate veil and assess the withheld portion of the payroll taxes against the individual(s) in the corporation who were responsible for “accounting, collecting and paying over” the payroll taxes. This is referred to as the Trust Fund Recovery Penalty (TFRP).
Form 940 is the form used by an employer to pay Federal Unemployment Tax. An offset against the Federal Unemployment Tax is given if the employer pays State Unemployment Tax.
When a 940 is timely filed, the IRS allows the taxpayer to check the box indicating that State unemployment tax has been paid. However, if a 940 is unfiled, employer must prove to the IRS that state unemployment tax has been paid by way of a certification. If this is not proven the federal unemployment tax increases about twenty-fold.

How to File Unfiled Tax Returns
Voluntary Disclosure — The Right Strategy for Complex Non-Filing. For taxpayers with many years of unfiled returns, particularly those involving significant unreported income, offshore accounts, or any facts that could be characterized as willful, a structured **Voluntary Disclosure** strategy is essential.
The IRS Voluntary Disclosure Practice provides a defined pathway for non-compliant taxpayers to come forward, cooperate with the IRS, and resolve their tax obligations in exchange for significantly reduced criminal prosecution exposure. Voluntary disclosure is not amnesty — you will still owe taxes, penalties, and interest. But coming forward proactively, truthfully, and completely before the IRS opens an examination is treated materially differently than being caught.
The key elements of a successful voluntary disclosure are:
– Filing accurate, complete returns for all required years
– Full cooperation with the IRS throughout the process
– Payment of taxes, interest, and applicable penalties, or an arrangement to pay
Voluntary disclosure strategy must be handled carefully. A disclosure that is incomplete, that contains errors, or that is structured without understanding how the IRS will evaluate it can make things worse rather than better. This is the work I have been doing since 1997, and the attorney-client privilege that covers the entire process is not incidental — it is foundational.
IRS Notices to Take Seriously
If you have received any of the following, do not ignore them and do not respond without representation:
– **CP-59** — First notice requesting a delinquent return. This is the IRS asking, not demanding. Respond promptly.
– **Letter 1058** — Final Notice of Intent to Levy. The 30-day window to request a Collection Due Process hearing is running.
– **Letter L-729** — IRS requesting delinquent return for a specific year.
– **IRS Form 12153** — Request for a Collection Due Process hearing. Filing this suspends levy action.
– **CP-3219A (Statutory Notice of Deficiency)** — Based on an SFR. You have 90 days to petition the Tax Court. Missing this deadline gives the IRS the right to assess and collect the SFR amount immediately.
The CP-3219A deadline is the one that most frequently results in preventable harm. A taxpayer who misses the 90-day Tax Court petition window loses the right to contest the SFR in Tax Court and the IRS can assess and begin collecting immediately.
Penalties and Interest — What You Are Actually Facing
For context on what accumulates on unfiled returns:
**Failure-to-File Penalty:** 5% of unpaid tax per month, up to 25% of the total unpaid balance. If the return is more than 60 days late, the minimum penalty is $485 (for returns due in 2024) or 100% of the unpaid tax, whichever is less.
**Failure-to-Pay Penalty:** 0.5% of unpaid tax per month, up to 25%. If both failure-to-file and failure-to-pay penalties apply in the same month, the failure-to-file penalty is reduced by the failure-to-pay amount — so the combined rate is 5% per month, not 5.5%.
**Interest:** The IRS currently charges **7% annually** on individual underpayments (Q1 2026), compounding daily. Interest runs from the original due date of the return and cannot be independently abated.
**Penalty abatement is available** for both failure-to-file and failure-to-pay penalties through First-Time Abatement or Reasonable Cause relief. In many non-filer cases, once the returns are filed and the correct liability is established, a meaningful portion of the assessed penalties can be challenged. Learn more about IRS penalty abatement
Penalties and Interest
Penalties and interest on late-filed tax returns and on unpaid taxes are significant. The Late Filing Penalty can be 25% of the unpaid balance, before credits. There are additional penalties for failing to make timely and proper Quarterly Estimated Tax Payments, failing to make timely and proper Federal Tax Deposits of payroll taxes, monthly Late Payment penalties for not paying on time, and many others. No one in the IRS can waive or abate penalties unless a taxpayer establishes “reasonable cause.” Reasonable cause is a very broad term, but generally involves disease, death, flood, fire, earthquake, etc. In addition, IRS or professional misrepresentation or erroneous advice can be reasonable cause. However, ALL reasonable cause claims must be proven with credible evidence. Interest rates on unpaid taxes change every six months and currently range from 3% to 4% compounded daily. Interest on past due taxes cannot be waived or abated by anyone in the IRS unless it can be proven that the IRS “failed to take a ministerial act.”
How I Handle Unfiled Return Cases
**Step 1 — Privileged consultation.** We discuss your situation under attorney-client privilege. I need to understand how many years are at issue, what type of returns (individual, business, payroll), whether any SFRs have been assessed, and whether any criminal exposure factors are present. This conversation shapes the entire strategy.
**Step 2 — Transcript pull.** I obtain your IRS account transcripts and Wage and Income Transcripts for all relevant years using a Power of Attorney. This tells me exactly what the IRS has assessed, what income was reported to the IRS, and what notices have been issued.
**Step 3 — Return preparation.** I prepare the delinquent returns as a CPA, using IRS transcript data and whatever additional documentation you have or we can reconstruct. Returns are prepared accurately — not minimally, and not inflated. The goal is a correct return that stands up to scrutiny.
**Step 4 — Filing strategy.** Not all delinquent returns are filed the same way or at the same time. The order of filing, the method of submission, and the accompanying communications to the IRS are all strategic decisions. Filing incorrectly — submitting all years at once without any coordination — can trigger immediate collection action before you have a resolution in place.
**Step 5 — Resolution.** Once returns are filed and the correct liability is established, we address the balance. Depending on your financial situation, that resolution may be an installment agreement, an Offer in Compromise, Currently Not Collectible status, or penalty abatement — often some combination.

Frequently Asked Questions
**How far back do I have to file?**
The IRS generally requires six years of delinquent returns to consider a taxpayer in compliance. However, if SFRs have been filed for specific years, or if the IRS has specifically requested returns for additional years, those years must be addressed. The six-year policy is administrative guidance, not a statute, and there are exceptions.
**What if the IRS has already filed Substitute for Returns for me?**
SFRs can be superseded by filing the actual return. Because SFRs are prepared without your deductions, exemptions, and credits, the actual return almost always shows a lower liability than the SFR. Filing your actual return replaces the SFR assessment and can substantially reduce what you owe.
**Can I go to jail for unfiled tax returns?**
Criminal prosecution requires proof of willful failure to file. Negligence, financial difficulty, procrastination, or simple avoidance does not typically meet the willfulness standard. That said, criminal risk increases with time and with any facts that suggest intentional concealment. If you have concerns about criminal exposure, the attorney-client privilege that attaches to our engagement is specifically why you want an attorney — not an accountant — handling this.
**What if I don’t have my records?**
Missing records are not a barrier to filing. I obtain IRS Wage and Income Transcripts that capture income reported by third parties for any year. For business expenses without documentation, there are recognized reconstruction methods. You do not need perfect records to file accurate, defensible returns.
**Will filing my back returns automatically trigger an audit?**
Filing delinquent returns does not automatically trigger an examination. The IRS processes delinquent returns as compliance filings. An audit is a separate determination based on the content of the return and IRS risk-scoring — not the mere fact that the return was filed late.
**How do I know if the IRS has already filed an SFR for me?**
Your IRS account transcripts will show any SFR assessments. I obtain these as part of the initial case analysis. If an SFR has been assessed and a Notice of Deficiency issued, there may be a Tax Court petition deadline in play — which is why early action matters.
Is There an IRS Amnesty Program for Unfiled Tax Returns?
There is no general IRS amnesty program that automatically forgives years of unfiled tax returns. Many taxpayers who simply fell behind can address their noncompliance through ordinary delinquent-return procedures. The analysis changes when the failure to file or report income may have been willful and creates potential criminal tax exposure.
The IRS Criminal Investigation Voluntary Disclosure Practice is intended for taxpayers with willful tax or tax-related noncompliance. A voluntary disclosure requires a truthful, timely, and complete disclosure through the IRS procedures and generally begins with Form 14457. It is not the same as simply filing past-due returns, and it does not automatically guarantee immunity from prosecution.
Most taxpayers with unfiled returns do not necessarily need VDP. The important question is whether the facts suggest ordinary delinquency or potentially willful conduct that should be evaluated before returns are filed.
Take the First Step
The longer unfiled returns sit unaddressed, the more the financial exposure grows and — in cases near the six-year mark — the narrower the available options become. Most clients who work through this describe it the way you might expect: the anticipation was worse than the reality. Getting into compliance removes a weight that typically compounds over time.
