The Most Common Form 1099 Filing Mistakes (and how to correct them)

Information return filing is a critical task for businesses throughout the year, but it is particularly important during tax season. These forms have specific rules, and mistakes can lead to substantial penalties and potential financial complications for your organization.

Information returns are a key part of how your organization communicates transparently with the IRS and the individuals you pay, with W-2 and 1099 forms being the most common types. Here’s what you need to know about these federal reporting requirements, including how to file a corrected 1099 form.

What is Tax Form 1099?

To understand Form 1099, it's helpful to compare it with Form W-2:

• W-2 forms are given to employees of a company.
• 1099 forms are given to independent contractors or used to report other types of income to recipients.

Whether you’re reporting payments to independent contractors, rent, or other types of income, the details matter. Here’s what your team needs to know to stay compliant, avoid common pitfalls, and ensure your 1099 filings support, rather than hinder, your business momentum.

Avoiding Common 1099 Filing Errors That Put Your Business at Risk

1. Not filing a form when a form is needed

The most frequent mistake we see is taxpayers neglecting to file an information return when one is required. There are several situations that require a Form 1099 or other information return to be filed. For instance, if you’re reporting payments to independent contractors, you’ll typically need to file a 1099 form.

2. Not filing by the due date

Timely filing isn't just about avoiding penalties — it's part of building a reliable foundation for decision-making, tax planning, and growth. Here are the key dates you need to keep in mind:

• February 1, 2027: Deadline for providing forms to recipients and filing Forms W-2 and 1099-NEC with the IRS
• March 1, 2027: IRS deadline for paper filing most other 1099 forms
• March 31, 2027: IRS deadline for electronic filing of most other 1099 forms

The best way to avoid issues with 1099 filing is to start preparing early. Review your vendor information before year-end to be sure you have all the Form W-9s and other information required to file these forms.

3. Completing the wrong form

Make sure you are using the correct Form 1099 variant (e.g., 1099-MISC for miscellaneous information, 1099-NEC for non-employee compensation) for each situation. Using the wrong type of form can lead to processing errors and may require filing corrected returns later. Also, if paper filing, be sure to use the correct year of the form and prepare the red Copy A to be filed with the IRS.

4. Using the wrong box on the form

Accurately filling out each box on 1099 forms affects how the IRS processes the information. For example, on Form 1099-MISC:

• Box 1 (Rent) may be reported on a 1040 Schedule E
• Box 3 (Other income) may appear on a 1040 Schedule C or other 1040 form

The IRS applies different tax rates and rules based on where income is reported on the form. Proper placement ensures correct tax treatment and helps avoid potential issues with federal income tax reporting later on.

5. Inaccurate Taxpayer ID Number (TIN) reporting

Be sure you are receiving and regularly updating the Form W-9 for your vendors to confirm you have appropriate information to file information returns at year-end. You can also go to the IRS website and run the information through a TIN verification to see if what you received from your vendor matches the IRS records.

It is also important to use the appropriate name for the TIN received. In some cases, you will receive a Social Security number for a Schedule C business but will receive the entity's doing business as (DBA) name instead of their personal name. When the IRS attempts to match the Social Security number with the DBA name in the system, they will not match because they will be expecting a person’s name. This will likely trigger an IRS Notice and penalty.

6. Using incorrect information to complete the form

Double-check your records to be sure you are using the appropriate amounts for the correct year and the correct vendor. Make sure you are using the vendor’s correct name and address for the form. Several accounting systems will track 1099 information for you, but they must be set up correctly.

7. Filing a paper return when filing electronically is required

New e-filing requirements, effective January 1, 2024, affect many taxpayers. The IRS issued new regulations notably reducing the threshold for the number of returns required to be electronically filed. Effective January 1, 2024 (for tax years ending on or after December 31, 2023), the threshold was reduced from 250 to 10.

The threshold of 10 includes the aggregate number of returns your business files to the IRS — not just 1099s. For example, if you file three W-2s and seven 1099s, you must e-file all forms.

The previous requirement was 250 returns of any one type. This change may affect those who have historically paper filed a limited number of many different returns and forms.

You can e-file with the IRS using the FIRE system or the IRIS program. In both cases, you will need to apply for a transmitter control code (TCC) to e-file. This process can take up to 45 days, so apply early to e-file by the deadline.

8. Omitting Form 1096 when paper filing

If you're mailing paper forms, don’t forget Form 1096. This transmittal form summarizes what you’re sending and keeps the IRS records accurate. One Form 1096 is required per type of 1099 filed.

9. Preparing forms that aren’t machine-readable

The IRS will machine read these forms. It is important to write legibly and in dark ink so the forms can be machine read correctly.

10. Formatting errors in key fields

Correctly formatting names, addresses, and other essential information impacts how accurately the IRS processes your forms. Since these documents are machine-read, even minor formatting errors can lead to misinterpretation. To ensure your forms are processed correctly:

• Follow the exact format specified by the IRS for each field
• Use capital letters for names and addresses
• Avoid special characters or punctuation unless specifically required
• Double-check the formatting of taxpayer identification numbers and payer names

How to Correct 1099 Mistakes and Strengthen Compliance

It is highly unlikely that you will go through 1099 filing season and not come across at least one required correction. Fortunately, correcting a Form 1099 is easy once you understand the process.

It is important to note that, unlike a Form W-2 correction form, Form W-2c, there is no separate 1099 correction form. It is the same form as the original 1099 with the “CORRECTED” box checked.

There are two types of 1099 errors to be corrected. Type 1 only requires one Form 1099 to be filed to correct the error. Type 2 requires two 1099 forms to be filed to make the correction.

Type 1 Errors

Type 1 errors occur when you file a form when one should not have been filed (in this case your corrected form would show zeros), or when you prepare a form with:

• An incorrect amount
• An incorrect code or checkbox
• An incorrect name or address for payee (but the correct TIN)

To correct Type 1 errors, file the correct form with the correct amount, code, checkbox, name, or address and check the “CORRECTED” box (generally located at the top of the form). If you used an account number on the original submission, be sure to use the same account number on the corrected form.

Submit the corrected 1099 form to the recipient and prepare the red Copy A to send to the IRS with the Form 1096 transmittal if paper filing. For electronic filing, you do not need to send in a Form 1096, nor should you mail in the originally filed forms with the correction to the IRS.

Type 2 Errors

Type 2 errors occur when you prepare a form with:

• Incorrect payer information, including the wrong Taxpayer ID Number (TIN)
• Incorrect recipient information, including the wrong TIN
• The wrong form type (e.g., a 1099-INT instead of a 1099-DIV)

To correct type 2 errors, you will need to file one corrected form along with the original.

The first 1099 will contain the exact same payer and recipient information as the originally filed form, but the amounts on the form will be all zeros and the “CORRECTED” box will be checked. This will remove the originally filed form from the IRS records.

Then, you will need to file a new Form 1099 with the appropriate information as an originally filed form (not a corrected form). Send the corrected and new original forms to the recipient and prepare the red Copy A to send to the IRS with the Form 1096 transmittal, if paper filing. A different Form 1096 is required for each type of Form 1099 filed. For electronic filing, you do not need to send in a Form 1096.

Additional Considerations for 1099 Corrections

The corrected form should be filed in the same way the original was filed. If the original was e-filed, the correction should be e-filed. If the recipient of the original form has different information in their records, they will likely contact you for an explanation and/or correction of the Form 1099.

Occasionally, this difference in records is due to a check being written from your bank account and not yet deposited in the recipient account. It is important to investigate differences noted by the recipients. The information reports on those forms will need to match what is reported on their tax return, and you don’t want to be the cause of incorrect information.

An IRS notice is the other main reason to amend a form. This generally relates to a TIN that doesn’t match what the IRS has for the recipient's name.

Just remember — when correcting forms, be sure to verify the type of error, so you know if you need to prepare one 1099 or two to complete the correction.
