How to File Back Taxes and Get Back on Track
If you are behind on filing tax returns, you generally fix it by filing the missing returns with the IRS (and your state tax agency, if you have one) and then arranging payment or a payment plan. You usually do not need a special program just to file late; you use the same tax forms, but penalties and interest are added, and collection actions may already be moving.
First Moves: What To Do This Week
The most useful first action most people can take is: figure out exactly which tax years you missed and whether the IRS has already filed a “substitute” return for you.
Get your IRS transcript.
Call the IRS main taxpayer help line or create/log in to your account through the official IRS online portal and request an Account Transcript and Wage & Income Transcript for each year you think you missed.
These show what forms (like W‑2s, 1099s) were reported under your Social Security number and whether a return is on file for that year.Make a simple year list.
On paper or in a spreadsheet, write down each year you did not file, or are unsure about, and note: “Return filed / Not filed / IRS filed SFR” (SFR = substitute for return, explained below).
This becomes your checklist and will be useful if you work with a tax preparer or clinic.Decide whether to start yourself or get help.
If you are missing only 1–2 recent years and your income is simple (only W‑2), you can often prepare the returns yourself.
If you have more years, self‑employment, or IRS letters already threatening levies or liens, contact a local Low‑Income Taxpayer Clinic (LITC) or a reputable tax professional before sending anything.
What happens after this step:
Typically, once you have transcripts and a year list, you or a preparer can begin drafting the back tax returns using the original year’s forms (for example, a 2019 return must use the 2019 Form 1040). When those returns are filed, the IRS later issues notices showing the balance due, including penalties and interest, and, if needed, you can then apply for a payment plan (installment agreement) or other resolution.
Who You Deal With: Official Tax System Touchpoints
For back tax filing, the main official agencies are:
Internal Revenue Service (IRS) – Handles federal income tax returns, balances, penalties, payment plans, and most collection actions (levies, liens, wage garnishments).
Search for the official IRS site or “IRS account” and make sure it ends in .gov.Your state’s Department of Revenue / Taxation – Handles state income tax returns, if your state has income tax.
Search for your state’s official “Department of Revenue” or “Tax Commission” portal and avoid look‑alike sites that are not .gov.
You normally cannot file federal or state returns through HowToGetAssistance.org or other information sites; you must file either electronically through official e‑file channels or by mailing paper returns to the address listed in the official instructions.
If you are low income, one more common touchpoint is:
- IRS Volunteer Income Tax Assistance (VITA) or Tax Counseling for the Elderly (TCE) sites – These are IRS‑sponsored programs where certified volunteers help prepare returns, including some prior‑year returns, for qualifying taxpayers for free.
Search for “VITA site locator IRS” and confirm you are on a .gov page.
Rules, forms, and income limits for help programs can vary by state and by your specific situation, so always check your local official portal.
Key Terms to Know
Key terms to know:
- Substitute for Return (SFR) — A return the IRS prepares for you when you do not file on your own, usually using only income reported by employers or payers; SFRs often overstate your tax because they assume no credits or deductions.
- Installment Agreement — A payment plan with the IRS that lets you pay a back tax balance over time, usually with automatic monthly debits.
- Currently Not Collectible (CNC) — A status where the IRS temporarily stops active collection because you cannot afford to pay right now, though the debt still exists and interest usually continues.
- Penalty Abatement — A reduction or removal of certain penalties (not the tax itself) when you qualify, for example under “first‑time abatement” or reasonable cause.
What to Gather Before You File Late Returns
To actually prepare and file back tax returns, you will typically need:
Documents you’ll typically need:
- All W‑2s and 1099s for each unfiled year (wages, unemployment, contract income, Social Security benefits, pension distributions, etc.).
- Records of deductible expenses or credits, such as 1098‑T (tuition), 1098‑E (student loan interest), childcare receipts, mortgage interest statements, or self‑employment expense logs.
- Any IRS or state tax notices or letters you received (for example, CP2000, CP14, CP501, CP504, or “Notice of Deficiency”), so you know what the government already thinks you owe.
If you are missing income forms, you can reconstruct them using:
- IRS Wage & Income Transcripts (pulled through your IRS account or by phone/mail request).
- Bank statements and pay stubs to estimate self‑employment income and expenses when no formal 1099s exist.
Keep everything organized by tax year, using separate folders. This matters because each return must reflect only that year’s income and deductions.
Step‑By‑Step: How Back Tax Filing Usually Works
Confirm which returns are missing
Use IRS transcripts and any state online account/transcript tools to see which years show “no return filed” or an SFR on record.
Next action today:Call the IRS help line and ask, “Can you tell me which tax years you show as unfiled under my Social Security number?” and write down the list.Check your state filing status
If you live in a state with income tax, search for your state’s official Department of Revenue or Taxation portal, create or log in to your account, and look for account history or “returns filed” by year.
If there is no online access, call the phone number on a prior state notice or from the official site and ask which years show as unfiled.Gather income and deduction records for each year
For each year, collect W‑2s, 1099s, 1098s, and key receipts; if you are missing forms, request Wage & Income Transcripts from the IRS and copies from employers or payers when possible.
Expect this to take days or weeks, especially if former employers have closed or payroll providers must be contacted.Prepare the returns using the correct year’s forms
Use the specific year’s Form 1040 and schedules (you can find prior‑year forms on the IRS .gov site) or work with a preparer who has prior‑year software.
For state returns, download prior‑year forms from your state’s .gov site or have a tax professional do them together with the federal return.File the completed back returns
For older years, you typically must mail paper returns to the address listed for that year’s form instructions; some recent prior years may still allow e‑file through professional software.
Use certified mail with return receipt if you can, and keep copies of everything you send.Wait for IRS and state processing
Once received, the IRS and state agencies process the returns; if an SFR was on file, your new return usually replaces it, potentially lowering your tax and penalties.
You will later receive notices showing if you owe, if a refund is due, or if the return was adjusted, typically by mail; timelines vary and can range from weeks to many months.Address balances due: pay, payment plan, or hardship status
If you owe, you can pay in full, request an Installment Agreement, or in hardship cases explore Currently Not Collectible status or an Offer in Compromise (settlement).
To start a simple payment plan, you can usually apply through the IRS Online Payment Agreement tool on IRS.gov or by calling the IRS collections line; for states, use your state’s portal or phone number.
Real‑world friction to watch for
One common snag is the IRS or state still sending collection notices or starting wage garnishment while your late returns or payment plan request are in process. If this happens, call the phone number on the notice immediately, explain that you are actively filing or have just filed back returns, and ask whether collection can be temporarily paused while the returns are processed; have your mailing dates or certified mail receipts ready when you call.
Scam Warnings and How to Avoid Bad Help
Because back taxes involve money, identity, and government programs, scams are common. Watch for:
- Impersonators: The IRS and state tax agencies do not demand payment by gift cards, prepaid cards, or cryptocurrency, and they generally first contact you by official letter, not text or social media.
- “Guaranteed” tax settlement companies: No legitimate professional can guarantee that the IRS will accept an Offer in Compromise or remove all penalties. Be cautious if they ask for large upfront fees or promise a result before reviewing your documents.
- Fake “IRS” websites: When accessing your account or forms, look for .gov addresses, and avoid clicking links from unsolicited emails or texts.
If someone pressures you to sign a power of attorney or payment plan on the spot, you can say: “I want to review this with another professional or directly with the IRS before I sign anything.”
Where to Get Legitimate, Low‑Cost Help
If your situation is complicated or you are already in collections, professional help is often worth it, especially if you qualify for free or low‑fee services.
Low‑Income Taxpayer Clinics (LITCs)
LITCs are often run by legal aid groups or law schools and can represent you in disputes with the IRS, help correct returns, negotiate payment plans, and sometimes assist with state issues.
Search for “Low‑Income Taxpayer Clinic list IRS” on a .gov site, then contact the clinic closest to you and ask about income guidelines and the types of cases they handle.VITA/TCE free tax prep sites
If your income is below certain limits or you are age 60+, VITA/TCE sites can often prepare current and some prior‑year returns at no cost.
When you call a site, ask: “Can you prepare back tax returns for tax year(s) [list years], and what documents do you require me to bring?”Enrolled agents, CPAs, and tax attorneys
These licensed professionals can represent you before the IRS and state agencies.
When choosing one, ask specifically: “How many back‑year or IRS collection cases do you handle, and what are your fees for each return and for dealing with the IRS?”
Quick phone script to an IRS line or LITC:
“My name is [First Name], and I believe I have unfiled federal tax returns for the years [list years]. I’ve started gathering my documents and transcripts, and I’d like to know what my options are for filing these returns and setting up a payment plan once they’re processed.”
Once you have your year list, transcripts, and initial documents, and you have contacted either the IRS/state or a legitimate tax‑help resource, you are in a position to move from “unfiled” to “filed and being resolved,” which is the key official next step in cleaning up back taxes.
