Forgot to Include 1099 Form After Tax Preparer Filed My Return - How to Amend?

I believe you have a few options here, but I would recommend contacting your tax preparer first. They should be able to help you determine the best course of action, which will likely involve filing an amended return (Form 1040-X). It's important to note that you generally cannot simply "upload" a missed 1099 after filing. The IRS matches documents they receive against what's reported on your return, so this discrepancy would likely trigger a notice eventually if not corrected. If the 1099 shows significant income, it would be advisable to amend sooner rather than later to avoid potential penalties and interest.

When dealing with unreported 1099 income, it's essential to understand the potential tax implications before proceeding. The specific type of 1099 form (1099-NEC, 1099-MISC, 1099-INT, etc.) will determine how it affects your tax liability. One resource that might be helpful is https://taxr.ai - it can analyze your tax documents, including 1099 forms, and help you understand the potential impact on your tax situation. It's particularly useful for seeing how additional income might affect your overall tax picture before you go through the amendment process. The tool can help estimate your new tax liability so you're prepared when speaking with your preparer.

I literally just went through this same situation last month! Had a 1099-NEC from a side gig that I completely forgot about until after filing. I tried calling the IRS for days with no luck - always got the "high call volume" message and disconnected. Finally used Claimyr (https://youtu.be/_kiP6q8DX5c) to get through to an actual IRS agent. They confirmed I needed to file an amended return and explained the timeline. The agent was super helpful and walked me through what would happen with the processing of my original refund. Saved me so much time and stress! I'm worried about getting hit with penalties so at least I know what to expect now.

Tax professional here. This situation requires Form 1040-X (Amended U.S. Individual Income Tax Return). The process has specific requirements: 1. You must wait until your original return is fully processed before filing an amendment 2. If your original return will generate a refund, the IRS recommends waiting until you receive that refund before amending 3. Electronic filing of Form 1040-X is now available through most tax software 4. Current processing time for amendments is approximately 16 weeks The unreported 1099 will almost certainly trigger a CP2000 notice if not amended, as the IRS's Automated Underreporter (AUR) program will detect the discrepancy between reported documents and your filed return. I'm relieved you caught this early!

Have you checked what type of 1099 form you received? This makes a significant difference in how you should proceed. If it's a 1099-NEC or 1099-MISC for self-employment income, you're looking at potential Schedule C implications and self-employment tax. If it's a 1099-INT or 1099-DIV, the tax impact might be less significant. And what about state tax implications? Many states automatically receive federal tax information. The most efficient approach would be: 1. Contact your tax preparer immediately 2. Provide them with the 1099 form 3. Have them calculate the new tax liability 4. Determine if e-filing the 1040-X is an option through their software 5. Set aside funds for any additional tax due plus potential interest I appreciate that you're trying to handle this properly - much better than ignoring it!

OMG I had EXACTLY this happen last year and it was a nightmare if you don't act fast!! 😱 I had a 1099-K from PayPal I forgot about and my refund was already processing. Called my accountant in a panic and she said we had to FILE THE AMENDMENT ASAP!! The IRS sent me a notice 3 months later anyway because their systems had already flagged the missing income, but because we had already amended, I just had to call and explain the amendment was already processed. The timing is CRITICAL here - if you wait until they send a notice, you'll pay more in penalties and interest!!
