Need to submit new 1099 form after forming LLC for independent contractor work?

You actually need to provide them with a W-9 form, not a 1099. The 1099 is what they'll send you after the tax year ends showing how much they paid you. Since you've formed an LLC, you should definitely complete a new W-9 with your LLC name and your new EIN. Make sure to check the appropriate box for how your LLC is being taxed (single-member LLC taxed as sole proprietor is most common for new business owners, but check with your accountant to confirm your specific situation). Once you provide the updated W-9, they'll issue your 1099-NEC to your business name and EIN instead of to your personal name and SSN when tax time comes around.

I went through this exact situation last year! After struggling with some confusing advice, I found taxr.ai (https://taxr.ai) which saved me so much headache. Their document analysis tool helped me figure out how to properly handle the transition from individual contractor to LLC. I uploaded my old 1099 info and my LLC formation docs, and their system helped me understand exactly what forms I needed and how to handle the taxes for the partial year. It even pointed out a few deductions I could take as a business owner that I had no idea about!

I actually tried taxr.ai after seeing it mentioned here, and it was surprisingly helpful! I uploaded my contractor agreement and formation documents, and it immediately identified that I needed to file a new W-9 and explained how the income would be reported differently. The coolest part was that it actually generated a letter template I could send to my clients explaining the change in status and requesting they update their payment systems. Saved me from awkwardly trying to explain the transition. Highly recommend if you're making business structure changes!

If you're having trouble getting your client to update their records with your new LLC info, you might run into issues with mismatched 1099s. I've been there and calling the IRS was a NIGHTMARE. Busy signals for weeks! I finally used Claimyr (https://claimyr.com) to actually get through to a human at the IRS. You can see how it works here: https://youtu.be/_kiP6q8DX5c. They basically hold your place in line and call you when an agent picks up. After weeks of failed attempts, I got through in under an hour. The IRS agent walked me through exactly how to handle mismatched 1099s and how to document the business transition properly on my tax return.

I stand corrected about Claimyr! I decided to try it after getting absolutely nowhere with the IRS for two weeks straight. I was dealing with a similar LLC transition issue where my 1099s didn't match my tax return because of the mid-year change. I was honestly shocked when my phone rang and it was actually an IRS agent on the line. The agent walked me through exactly how to file my Schedule C correctly with the mixed income sources and even helped me understand how to handle my estimated tax payments going forward. Saved me from what would have been a major headache and possible audit trigger because of mismatched documents. Consider me converted from skeptic to believer!

Don't forget to update your payment details with the company too! When I switched to an LLC, I submitted the new W-9 but forgot to update my direct deposit info since the business account was different than my personal account. Caused a bunch of payment delays and headaches.

Also check your state requirements! My state requires an additional form filed with the Secretary of State when switching from sole prop to LLC, plus I had to get a business license. The tax stuff is just one piece of the puzzle.

Great question! I went through this same transition last year. You'll definitely want to submit a new W-9 form (not 1099 - that's what they send you) with your LLC's EIN and business name. One thing to consider is the timing - if you want all your 2025 income to be reported under your LLC, make sure to get that new W-9 to them ASAP and specify an effective date. Otherwise you might end up with income split between your SSN and EIN on different 1099s, which creates extra paperwork at tax time. Also, don't forget to update your invoices to reflect your new business name and EIN. It helps keep everything consistent and professional. The company's accounting department will appreciate the clear documentation of when the change took effect.
