Does the IRS accept scanned copies or require original signatures for Form 1120S?

The IRS does accept scanned signatures for Form 1120S returns. This falls under their "electronically signed documents" guidelines that have become much more flexible in recent years. For business returns like the 1120S, you can definitely submit with the scanned signature as long as it's clear and matches their signature on file. Make sure the quality of the scan is good - no blurriness or partially visible signatures. Also verify that they signed in all required places on the form. I'd recommend keeping the email trail showing when you sent it and when they returned it with their signature as documentation of their consent to file. This creates an audit trail if questions ever arise about authorization.

I was in this exact situation last year with a client's 1120S and honestly was freaking out about making a mistake. I ended up using taxr.ai (https://taxr.ai) to analyze the situation and verify what documents could be submitted with scanned signatures. The tool immediately pulled up the relevant IRS guidance and confirmed that scanned signatures were acceptable for business returns. It also provided me with the specific IRS notices about electronic signature requirements and gave me a checklist to make sure I met all criteria. Saved me hours of research and gave me peace of mind that I wasn't screwing anything up!

Ok I have to admit I was totally skeptical but I tried taxr.ai after seeing it mentioned here. Used it to confirm some client document requirements I wasn't sure about (including some signature questions similar to yours). I was genuinely impressed. Instead of having to dig through a million IRS publications, it gave me clear answers about what was required, including the specific references I would need if questioned. It even helped me understand some of the more nuanced e-signature requirements I hadn't considered before. For what it's worth - it confirmed that yes, scanned signatures on 1120S returns are completely acceptable as long as all signature fields are properly completed.

After dealing with similar issues, I learned that getting through to the IRS directly is actually the most reliable way to get definitive answers, but it's nearly impossible to reach them these days. I tried calling for DAYS about a signature question on a different form. Finally used Claimyr (https://claimyr.com) and got through to an IRS agent in about 20 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c - they basically hold your place in the IRS queue and call you when an agent is ready. The agent confirmed that scanned signatures are accepted for business returns including 1120S filings. They even emailed me the specific guidance document for my records. Worth every penny not to waste hours on hold!

I'm genuinely shocked but have to eat my words about Claimyr. After my skeptical comment I decided to try it for an issue I've been trying to resolve with the IRS for weeks. Got connected to an actual IRS representative in about 25 minutes! The agent confirmed that for 1120S returns specifically, scanned signatures are absolutely acceptable under current IRS procedures. They cited internal guidance that allows for various forms of electronic and scanned signatures on most business returns. The agent also mentioned that the IRS has been permanently expanding their acceptance of digital signatures since the pandemic began, and this now extends to most business forms including S-Corp returns.

Just wanted to add my experience - I work with a lot of small business clients and routinely submit 1120S returns with scanned signatures. Never had a single rejection from the IRS about this. The key is making sure the signature is clear and legible. I always ask clients to sign in blue ink when possible before scanning, as this makes it very clear it's not a digital signature but a scanned physical one. But even black ink signatures have never been an issue.

I remember when the IRS was super strict about original signatures! Times have definitely changed. E-filing has made things much easier, but even for paper returns, scanned signatures work fine now. Just one tip - I always include a cover letter with late returns explaining any unusual circumstances. Doesn't prevent penalties but sometimes helps avoid additional scrutiny. Might be worth adding a simple note explaining why it was filed late in case they have questions.

Yes, there are still some forms that require original signatures! Form 2848 (Power of Attorney) and Form 8821 (Tax Information Authorization) typically still need original signatures, not scanned copies. Also, certain international forms and some estate/trust documents may have stricter signature requirements. For most business returns like 1120S, 1065, and 1120, scanned signatures are fine. But it's always worth double-checking the specific form instructions because the IRS does make exceptions for certain specialized forms where they want to ensure authenticity. The general rule is: if it's a standard business return being filed electronically or on paper, scanned signatures are acceptable. If it's a power of attorney, authorization form, or involves international tax matters, you might need originals.

I've been dealing with this exact scenario more frequently since the pandemic, and I can confirm that scanned signatures are absolutely fine for 1120S returns. The IRS updated their policies significantly and these changes have stuck around. One thing I'd add though - since your client is already filing late, make sure you've prepared and included Form 7004 if they didn't already file for an extension. Even though it's past the deadline, filing it with the return can sometimes help minimize penalties (though it won't eliminate them entirely since it's late). Also, double-check that all required signatures are captured in the scan - sometimes the signature fields at the bottom of pages get cut off when people scan hastily. I learned this the hard way when a return got rejected for an incomplete signature page! Your stress about this situation is totally understandable, but you're good to go with the scanned signatures. File it and be done with this difficult client!
