To file a 2013 tax return in 2026, download the 2013 version of Form 1040 and its instructions from the IRS prior-year forms archive, complete the return using 2013 tax rules, and mail it to the paper-return processing center assigned to your state. You cannot file electronically, and you cannot claim a refund: the deadline to collect a 2013 refund passed on April 18, 2017, and any overpayment now belongs to the U.S. Treasury.1Internal Revenue Service. Time Running Out to Claim $1 Billion in Tax Refunds from 2013 What remains is closing out an obligation, and the mechanics below walk through each step.
Why People Still File a 2013 Return
Three situations bring people back to a tax year this old. The most common is IRS enforcement. If you never filed, the IRS may have prepared a Substitute for Return using only the income figures employers and banks reported, without any deductions, credits, or favorable filing status you would have qualified for. Those substitute returns almost always overstate the tax owed, and filing your own return replaces the substitute figures.2Taxpayer Advocate Service. Consequences of Not Filing
The second is a compliance hold. Mortgage underwriters and government agencies pull tax transcripts, and a missing year can stall a loan or an immigration case until it’s cleared. The third is voluntary cleanup — closing the book on an old year before the IRS starts collection activity.
Which 2013 Form You Need
Most people filing this late will use Form 1040, the full-length return. It’s required if your 2013 taxable income was $100,000 or more, if you itemized deductions on Schedule A, or if you had self-employment income reported on Schedule C. Two shorter forms also existed for 2013: Form 1040A for taxpayers under $100,000 in taxable income who didn’t itemize, and Form 1040EZ for the simplest single or joint filers with no dependents and only wage, interest, unemployment, or scholarship income.3Internal Revenue Service. 2013 Form 1040EZ Instructions
Self-employment income requires Schedule C for profit or loss and Schedule SE for self-employment tax.4Internal Revenue Service. 2013 Instructions for Schedule C Profit or Loss From Business
The 2013 Numbers You’ll Use
The 2013 standard deduction was $6,100 for single or married filing separately, $12,200 for married filing jointly or qualifying widow(er), and $8,950 for head of household. Each person listed on the return — you, your spouse if filing jointly, and every dependent — also reduced taxable income by a $3,900 personal exemption.5Internal Revenue Service. 2013 Publication 501 – Exemptions, Standard Deduction, and Filing Information These figures apply only to 2013. Use the 2013 instruction booklet for your form, not the current one, because tax brackets and credit phase-outs change every year.
Finding Your 2013 Income Records
This is the hardest step, and your options have narrowed with time.
IRS Wage and Income Transcripts
The IRS makes wage and income transcripts available for the current year plus the prior ten years.6Internal Revenue Service. Topic No. 159 – How to Get a Wage and Income Transcript In 2026, that window reaches back to 2016, so 2013 wage and income data is no longer accessible through the transcript system.
Form 4506 for a Prior Return
If you actually filed a 2013 return and want a copy, Form 4506 requests a photocopy for $30. The IRS keeps copies of individual returns for seven years from the filing date and then destroys them, which puts a 2013 return filed in April 2014 out of reach around 2021.7Internal Revenue Service. Form 4506 – Request for Copy of Tax Return
What Actually Works
Contact your 2013 employers and financial institutions directly. Some payroll providers keep records longer than the IRS keeps transcripts, and banks can sometimes retrieve 1099-INT data from archived account statements. If you used tax software or a paid preparer in 2013, they may still have the return or the source documents. When nothing else survives, reconstruct income from bank statements, deposit records, and any pay stubs you kept. The IRS will accept a return built from the best available information, though your figures may be compared against whatever the agency has on file.
Downloading the 2013 Forms
The IRS keeps prior-year forms at its Prior Year Forms and Instructions page.8Internal Revenue Service. Prior Year Forms and Instructions Filter by 2013 and download Form 1040 (or 1040A or 1040EZ), the matching instruction booklet, and any schedules you need — Schedule A for itemized deductions, Schedule C and Schedule SE for self-employment, and so on. Everything comes as a PDF you print, complete by hand or with a PDF editor, and mail.
Filling Out the Return
Filing Status
Your filing status is based on where you stood on December 31, 2013, not today.9Internal Revenue Service. IRS Tax Tip 2013-13 – Determining Your Correct Filing Status Married on that date means you can file jointly or separately for 2013. Unmarried but supporting a child in your home usually qualifies you for head of household, which carries a larger standard deduction than single.
Identifying Numbers
Everyone on the return needs a Social Security number or an Individual Taxpayer Identification Number, because federal law requires an identifying number on every return.10Office of the Law Revision Counsel. 26 USC 6109 – Identifying Numbers If you or a dependent needs an ITIN, file Form W-7 with the tax return, leave the SSN field blank for that person, and the IRS will assign the number and process the return.11Internal Revenue Service. How to Apply for an ITIN
Calculating the Tax
Work through the 2013 instructions in order. Total your income, subtract adjustments to reach adjusted gross income, subtract either the standard deduction or your itemized total, then subtract $3,900 for each personal exemption. Look up the resulting taxable income in the 2013 tax table. Apply any 2013 credits, subtract withholding already paid, and the bottom line is either a balance due or an overpayment. An overpayment for 2013 will not be refunded and cannot be applied to another year.5Internal Revenue Service. 2013 Publication 501 – Exemptions, Standard Deduction, and Filing Information
Where to Mail the Return
The correct address depends on your state and whether you are enclosing a payment. The IRS publishes a full state-by-state table on its Where to File Paper Tax Returns page, and you should check it before you seal the envelope.12Internal Revenue Service. Where to File Paper Tax Returns With or Without a Payment Returns without a payment go to one of three processing centers in Austin, Kansas City, or Ogden. Returns with a payment go to a lockbox address, typically in Charlotte or Louisville. Sending a return to the wrong center delays processing.
Use certified mail with return receipt requested. The postmark date is what the IRS uses for penalty calculations, and you’ll want documented proof of it. Photocopy the entire return and every attachment before mailing.
If you owe, include a check or money order payable to “United States Treasury” with your name, SSN, and “2013 Form 1040” written on the memo line. You can also pay online through IRS Direct Pay, which lets you use the no-payment mailing address for the return itself.
Penalties and Interest
A 2013 return filed now is roughly twelve years late, and if you owe tax, the penalties reached their ceilings years ago.
The failure-to-file penalty is 5% of the unpaid tax per month, capped at 25% of the tax due.13Internal Revenue Service. Failure to File Penalty The failure-to-pay penalty is 0.5% per month, also capped at 25%.14Internal Revenue Service. Failure to Pay Penalty Both penalties on a 2013 balance are maxed out. When they overlap in the same month, the failure-to-file penalty is reduced by the failure-to-pay amount, so the combined ceiling is 47.5% of the original tax.
Interest is the bigger number. It compounds daily on the unpaid tax and on accumulated penalties, with no cap, and the rate changes quarterly. For the first quarter of 2026, the individual underpayment rate is 7%, dropping to 6% for the second quarter.15Internal Revenue Service. Quarterly Interest Rates Over twelve years at fluctuating rates between roughly 3% and 8%, interest can rival or exceed the original tax. Interest is not abatable except in narrow situations involving IRS error.
Asking for Penalty Relief
Two paths exist. First-time penalty abatement applies if you had a clean compliance record for the three years before the 2013 penalty. Reasonable cause relief applies if something outside your control — serious illness, natural disaster, reliance on a preparer who failed to file — kept you from filing on time. Request either by calling the number on an IRS notice or by submitting Form 843.16Internal Revenue Service. Penalty Relief for Reasonable Cause Abatement removes the penalty; the underlying interest stays.
If You Can’t Pay the Full Balance
File anyway. Filing without payment stops the failure-to-file clock (to the extent it hasn’t already maxed out) and shows the IRS you’re cooperating. Once the balance is assessed, you have options:
- A short-term payment plan of up to 180 days if you owe less than $100,000 in combined tax, penalties, and interest.
- A long-term installment agreement if you owe $50,000 or less and have filed all required returns. Set it up through the IRS Online Payment Agreement tool or by filing Form 9465. During an active agreement, the failure-to-pay penalty drops to 0.25% per month.14Internal Revenue Service. Failure to Pay Penalty
- An Offer in Compromise, where the IRS accepts less than the full balance if that amount reflects the most it can reasonably collect. Qualifying is harder than most people expect.
Interest continues to accrue on any unpaid balance no matter which arrangement you use.
The 10-Year Collection Clock
Federal law gives the IRS ten years from the date it assesses a tax to collect it, after which the remaining balance is written off.17Office of the Law Revision Counsel. 26 USC 6502 – Collection After Assessment This date is the Collection Statute Expiration Date, or CSED. For 2013 tax, the CSED depends on when the assessment happened. If a Substitute for Return was assessed in 2016, the ten-year window closes around 2026. If you file your own return now and the IRS assesses a different amount, a new ten-year clock starts on that newly assessed balance.18Internal Revenue Service. Time IRS Can Collect Tax
Understand this before filing. Replacing a Substitute for Return can lower what you owe, but it can also reset the collection clock on the reduced balance. Certain actions also pause the clock: bankruptcy (for the case duration plus six months), a pending installment agreement request, a pending Offer in Compromise, and a Collection Due Process hearing.19Taxpayer Advocate Service. Collection Statute Expiration Date (CSED) You can check your CSED by ordering an account transcript, where the date appears next to a three-digit IRS code in the transactions section.
After You Mail It
Paper returns generally take six to eight weeks to process, and a late-filed historical return often takes longer because the IRS reconciles it against existing records, including any Substitute for Return already on file.20Internal Revenue Service. IRS Tax Tip – Refunds, How Long Should They Take You’ll receive a notice showing the assessed tax, penalties, and interest. If your figures were adjusted, the notice explains the changes, and you have the right to dispute them.
If you filed to clear a mortgage or immigration hold, request an account transcript once processing finishes. For a tax year this old, account transcripts confirming that you filed and showing the assessed balance are more likely to be available than a full return transcript.
