How to Find Unfiled Business Tax Returns

The short answer: Start with the IRS. The complete entity transcript lists the returns the IRS expects from your company, and an account transcript for each year or quarter shows whether one was filed. Then check Florida’s eFile and Pay records for sales tax and reemployment tax, the company’s Sunbiz record for annual reports, and your payroll records for Forms 941, 940, W-2 and 1099-NEC. Every gap, by form and period, goes on one list.

What does the IRS expect your company to file?

The complete entity transcript tells you (the modified version leaves out filing requirements, so ask for the complete one). Its filing requirements list the returns the IRS expects, such as Form 1120 or 1120-S, and Forms 941 and 940 if the company registered as an employer.

A quiet year doesn’t take the income tax return off that list: a domestic corporation must file one whether or not it has taxable income.

Check which income tax form it lists. Form 1120-S applies only if the company elected S corporation status on Form 2553, the IRS accepted the election, and it’s still in effect. If the transcript says Form 1120 but you’ve always treated the company as an S corporation, raise it with whoever will prepare the returns before anything is filed, because it decides which form each missing year needs. Our guide to a late S corporation election explains the options.

Which transcript shows whether a return was filed?

The account transcript. For one year or quarter, it shows the return’s filing and processed dates, payments, deposits, penalties, interest and any balance due. No filing date means the IRS has no processed return for that period. The IRS says account transcripts are available for most returns, so order them for older years.

A return transcript shows a filed return’s line items (for Form 941, tax years 2023 and later only). A Verification of Nonfiling is the IRS’s proof that no return was filed for a year.

How do you get IRS transcripts for a corporation?

Online, in Business Tax Account. Companies that file Form 1120 or 1120-S can use it through a Designated Official. That’s an officer or managing member who can legally bind the company and is a current employee who received a W-2 for the most recent tax filing year. The role has to be renewed every year.
By mail or fax, on Form 4506-T. It covers account and return transcripts and a Verification of Nonfiling, but not the entity transcript. Enter one form number per request, and list each quarter for quarterly returns. An officer with authority to bind the corporation signs it. Transcripts go only to the address the IRS has on record, and most requests are processed within 10 business days.
By phone, on the IRS Business and Specialty Tax Line, which can also give you the entity transcript: 800-829-4933, Monday to Friday, 7 a.m. to 7 p.m. your local time. If no officer is on the payroll, this is the way to get it.

What else shows what the IRS is waiting for?

EFTPS, the Electronic Federal Tax Payment System, shows 15 months of the federal tax payments made through it under your EIN. A payroll tax deposit in a quarter means a Form 941 should exist for that quarter. Older payments and deposits appear on the account transcript.

Then go through the mail. A CP259 notice names a form and tax period the IRS says a return is required for but hasn’t received. The IRS sends one for each form and period, so gather them all. If you have one, see our guide to an IRS letter about a missing business return.

What does Florida have on record?

The Florida Department of Revenue expects a return for every period of each tax your company is registered for, even when nothing is owed.

Sales and use tax: a return for each reporting period, even with no tax due; most new businesses file quarterly. A late return can draw a penalty of 10% of the tax, at least $50 even with no tax due, plus interest on tax paid late. Florida settles that penalty automatically if the company had no other late filing or payment in the previous 12 months and owes nothing else (s. 213.21(10)).
Reemployment tax (RT-6): a report every quarter, even with no wages. It’s due the first day of the month after the quarter ends and late if not postmarked by the last day of that month, with a penalty of $25 for each 30 days, or part of 30 days, it’s late.
Corporate income tax (F-1120): every year for a corporation, even with no tax due, and for an S corporation in any year it owes federal tax on the Form 1120-S itself (line 23c on 2023 and later forms, line 22c on earlier ones).

If the company collected sales tax and didn’t send it in, Florida treats that more seriously than a late return (s. 212.15), so it’s worth speaking with a Florida tax attorney before those periods are filed.

Sales tax moved to Florida’s new eFile and Pay system on December 1, 2025, and reemployment tax on August 24, 2026. Older filing history stayed in the old systems, and the Department ends access to them after September 30, 2026. For earlier returns, request copies at any time on Form DR-841, Request for Copy of Tax Return. The Department’s taxpayer assistance line is 850-488-6800.

What does Sunbiz show?

Look the company up by name or document number on Sunbiz, the Division of Corporations’ site, and check its status and which annual reports are on file. Any year with no annual report is a gap.

The annual report is due between January 1 and May 1, with a $400 late fee after May 1. A company that hasn’t filed it by 5 p.m. Eastern on the third Friday in September can be administratively dissolved. You can file it yourself online on Sunbiz.

Which payroll filings belong to each year?

For payroll and contractors, the IRS expects:

Form 941 for each quarter, due by the last day of the month after the quarter ends. After the first 941, one is due every quarter, even with no wages, until a final return is filed (seasonal employers excepted). A company the IRS has told in writing to file Form 944 files once a year instead.
Form 940, due by January 31, for any year the company paid $1,500 or more in wages in a calendar quarter or had an employee in 20 or more weeks, or did either the year before
Forms W-2 and W-3 for each year wages were paid, filed with the Social Security Administration and given to employees by January 31
Form 1099-NEC for each contractor paid at or above that year’s reporting threshold, due to the IRS and each recipient by January 31

Florida’s RT-6 goes in every quarter alongside them. A payroll provider’s year-end reports show what it filed, and the account transcript for each Form 941 quarter confirms whether the IRS received it.

How far back should you look?

Go back to a year you know is complete, then check every period after it. IRS Policy Statement 5-133 says enforcement of delinquent returns normally covers not more than six years, and going further needs managerial approval.

That’s IRS policy, not law: when no return is filed, the IRS can assess the tax at any time, and the policy sets aside cases with signs of willful failure to file or fraud. Florida’s Department of Revenue can also assess at any time when a required return wasn’t filed. If you’re unsure how far back to go, ask an attorney, a CPA or an enrolled agent.

A simple checklist

Get the complete IRS entity transcript and list every form under filing requirements.
Get an account transcript for each form and period since the last return you know was filed.
Add the form and period from any IRS notice, such as a CP259.
Match EFTPS payroll deposits to quarters.
Check Florida eFile and Pay for sales and reemployment tax; request older copies on Form DR-841.
List every F-1120 year for a C corporation, and any year an S corporation owed that tax.
Note the company’s Sunbiz status and any year without an annual report.
From payroll records, list the 941, 940, W-2, 1099-NEC and RT-6 filings for each year.
Put it on one page: filings down the side, years across the top, each marked filed, missing or not required.

That page is what a catch-up is built from. Cayde rebuilds the books behind it and gets the agreed late federal and Florida filings done, with a fixed quote in writing first.

Quick answers

Why can’t I get into the company’s IRS Business Tax Account?

Usually it’s the Designated Official rules: the person must be an officer or managing member who can bind the company and a current employee with a W-2 for the most recent tax filing year. Without one, call 800-829-4933 for the entity transcript, and use Form 4506-T or the same line for account transcripts.

The company moved. Where will the IRS send the transcripts?

Only to the address the IRS has on record. If it’s out of date, file Form 8822-B to change the business address before sending Form 4506-T.

Can someone else order the transcripts for us?

Yes. A tax professional you authorize on Form 8821 or Form 2848 can order your transcripts through the IRS’s Transcript Delivery System. For the complete entity transcript, line 3 must say “Business entity transcript” or “Entity information,” and they call the IRS Practitioner Priority Service line.

Does a Verification of Nonfiling mean the company didn’t have to file?

No. It only confirms the IRS has no record of a return for that year. Whether one was required depends on the rules for that form: a domestic corporation must file an income tax return whether or not it has taxable income. The entity transcript’s filing requirements show what the IRS expects.

We just filed a missing return. Why isn’t it on the transcript?

It takes time to post. The IRS says to allow 2–3 weeks after e-filing, or 6–8 weeks after mailing a paper return, before requesting a transcript.
