If you’re filing 1099 forms for independent contractors, vendors, or freelancers, it’s crucial to get everything right — from data entry to IRS submission. But even with e-filing platforms making the process easier, there are still common pitfalls that could lead to delays, penalties, or compliance issues.
In this guide, we’ll cover the top 5 mistakes to avoid when e-filing 1099 forms online, and how platforms like eFileMy1099 help you stay compliant and stress-free.
Missing or Incorrect Taxpayer Information (TINs)
One of the most common — and avoidable — errors is submitting a 1099 form with the wrong Taxpayer Identification Number (TIN) or mismatched name/TIN combinations.
If the IRS can’t match the recipient’s name to the TIN, you risk rejections or penalties.
How to avoid it:
eFileMy1099 includes TIN verification tools to validate the information before submission. This reduces the risk of IRS mismatches and improves your acceptance rate.

Using the Wrong Form Type (NEC vs MISC)
Another frequent mistake is choosing the wrong form type — for example, filing Form 1099-MISC instead of 1099-NEC for nonemployee compensation.
Since 2020, the IRS requires businesses to report contractor payments using 1099-NEC, not MISC.
How to avoid it:
eFileMy1099 walks you through the form selection process and clearly distinguishes between 1099-NEC, 1099-MISC, 1099-INT, and other types, so you file the right form every time.

Filing Late or Missing IRS Deadlines
Filing too late (or not at all) is a surefire way to rack up penalties.
IRS deadlines for 1099 e-filing typically fall around January 31st to March 31st, depending on the form and filing method.
How to avoid it:
Use eFileMy1099 to track your progress, get reminders, and instantly e-file with the IRS in just a few clicks.
→ Bonus: We handle both e-delivery and mail delivery of recipient copies too.
Not Sending Recipient Copies
Sending a 1099 to the IRS isn’t enough. You’re also legally required to deliver a copy to the recipient — whether it’s a freelancer, contractor, or vendor.
How to avoid it:
eFileMy1099 automates this process. After you e-file, we email or mail recipient copies securely, saving you the hassle of printing and postage.

Manual Data Entry or Spreadsheet Errors
If you’re uploading large amounts of data or managing bulk 1099 filings through spreadsheets, manual copy-paste errors can become a serious issue.
Wrong amounts, duplicate entries, or missed recipients all lead to incorrect filings.
How to avoid it:
eFileMy1099 supports bulk import via Excel/CSV, and offers a clean interface to review and validate data before final submission.
