Just wanted to add that if you're planning to pay off your tax debt immediately anyway, you might want to look into the IRS Fresh Start program. Sometimes they offer penalty abatement if you pay in full. Might save you a chunk of money since penalties can add up fast on $13,500!

Great advice from everyone here! As someone who's dealt with IRS collections professionally, I can confirm that without formal levy notices, your account won't be automatically frozen when the deposit hits. The IRS has to follow strict procedural requirements before taking funds. One additional tip - when you do pay off that $13,500, make sure to get a zero balance transcript from the IRS afterward to confirm everything is properly credited. Sometimes payments can take a few weeks to fully process, and having that documentation protects you if any collection notices were already in the mail before your payment cleared. Also, definitely explore that Fresh Start program Sophia mentioned. First-time penalty abatement can be significant on a debt that size, especially if you've been compliant with filings and payments since the business closed. Worth a phone call to ask about it when you make your payment.

Just to add a practical tip - I keep a specific "FHL booking log" spreadsheet that tracks all stays including days between bookings. This makes it easy to demonstrate to HMRC that I'm meeting all the FHL criteria. For repeat guests, I make a point of having them sign a specific checkout form confirming they're fully vacating the property at the end of each stay. When they return later, they sign a completely new booking form. I've been doing FHL rentals for 5 years and have had repeat guests do multiple 30-day stays within the same tax year without problems. As long as your documentation clearly shows these are separate holiday bookings, you should be fine.

This is really helpful information from everyone! I've been dealing with a similar situation with my holiday cottage in the Cotswolds. What I've learned from my accountant is that the key is demonstrating genuine commercial availability between stays. One thing I do that might help others - I make sure to update my property listing on booking platforms immediately after each guest checks out, showing it's available for the gap period between their stays. Even if the same guest has already booked the next period, having that evidence of commercial availability helps demonstrate it's not just a disguised long-term let. Also worth noting - I've found that having a minimum 7-day gap between stays by the same guest gives you a much stronger position if HMRC ever questions it. It shows the property was genuinely available to other holidaymakers and that you're not just trying to game the 31-day rule. The checkout documentation suggestions here are spot on too - I wish I'd started doing that from the beginning!

I've been following this discussion closely as I'm dealing with a very similar DBA situation with my IT services company. What strikes me most from reading everyone's experiences is how this really comes down to professional presentation rather than finding some magical IRS form. The consensus seems clear: create a comprehensive documentation package that includes your EIN assignment letter, DBA certificate, and a formal declaration letter using proper tax terminology. The approach @ApolloJackson outlined with the "DBA-EIN Relationship Declaration" language appears to be the most practical and widely accepted solution. For those still struggling with this, I'd recommend focusing on these key elements: 1) Professional letterhead for your declaration letter, 2) Specific language referencing federal tax compliance, 3) Clear statement that both names operate under the same EIN, and 4) Supporting documentation (EIN letter + DBA certificate). The CPA verification letter seems to be the "premium" option that adds extra credibility for particularly demanding clients, but the basic three-piece package appears sufficient for most situations. One thing I haven't seen mentioned - has anyone tried including a copy of their business insurance policy that shows both business names? I'm wondering if that adds another layer of legitimacy to the documentation package. Thanks to everyone who shared their real-world experiences. This thread is a goldmine of practical advice for navigating corporate compliance requirements!

This has been such a helpful thread! I'm dealing with the exact same situation with my graphic design business - I operate legally as "Creative Solutions LLC" but also have a DBA called "Pixel Perfect Designs" that I use for my freelance work. What really resonates with me from reading everyone's experiences is that this isn't about finding some special IRS form or procedure - it's about creating professional documentation that clearly establishes the relationship between your legal business name and your DBA under one EIN. The three-piece documentation package approach that @ApolloJackson outlined seems to be the gold standard: formal declaration letter on letterhead, EIN assignment letter, and DBA certificate. I love how straightforward yet professional this approach is. I'm particularly interested in @Zoe's suggestion about including business insurance documentation. My commercial policy actually lists both business names, so that could add another layer of third-party validation to the package. For anyone still struggling with this issue, the key takeaway seems to be: focus on professional presentation and clear documentation rather than trying to find a non-existent IRS form. The declaration letter using proper tax terminology appears to be what really makes the difference with corporate compliance departments. Thanks to everyone for sharing their real-world experiences - this community has saved me weeks of frustration trying to figure this out on my own!

I completely understand your anxiety - I went through something very similar last year! I forgot to include a 1099-INT for about $87 and was convinced I was going to get audited when I filed my amendment. The good news is that amended returns for small amounts of missing interest income are extremely routine. The IRS processes thousands of these every day, and they actually view self-correction favorably compared to having to send you a notice later. Your $105 in interest would only increase your actual tax owed by roughly $25-35 depending on your bracket, which is genuinely not worth the IRS's time to scrutinize given their limited resources. They're focused on much larger discrepancies and more complex issues. My amended return took about 14 weeks to process (filed in March), but I eventually got my adjusted refund without any additional contact from the IRS. No audit, no letters, nothing - just the corrected refund amount. I know the waiting is stressful, especially when you're counting on that money for your dental work, but try to remember that you did exactly the right thing by catching and correcting this yourself. That demonstrates good faith compliance to the IRS, not suspicious behavior.

I completely understand your anxiety about this! I was in almost the exact same situation a few months ago - forgot a 1099-INT for about $95 and was absolutely convinced that amending my return would somehow flag me for an audit. Here's what I learned: filing an amended return for small amounts of missing interest income is incredibly routine for the IRS. They process thousands of these every week. The fact that you're correcting it yourself before they have to contact you actually works in your favor - it shows good faith compliance rather than trying to hide something. Your $105 in interest would only increase your actual tax liability by maybe $25-30 depending on your tax bracket. The IRS is dealing with much bigger issues than people who forgot small interest payments. They're focused on major discrepancies, unreported business income, or suspicious deductions - not honest mistakes on tiny amounts of interest. My amended return took about 13 weeks to process, which was frustrating because I was also counting on my refund for something important. But I eventually got the adjusted refund without any additional contact from the IRS. No audit, no letters, no drama - just the corrected amount. I know the waiting is stressful, especially with your dental work planned, but you absolutely did the right thing by correcting this proactively. Try not to let the anxiety spiral - you're going to be fine!

I'm actually a real estate agent who does occasional flips. My tax guy always has me separate my activities: 1. Agent income (Schedule C) 2. Flips as dealer (Schedule C if I do more than 2-3 per year or hold less than 12 months) 3. Flips as investor (Schedule D if it's occasional and I hold longer) 4. Rentals (Schedule E) The biggest mistake I see people make is being inconsistent from year to year without documenting why their activity changed. If you're going to switch between investor/dealer treatment, make sure you can justify the different treatment based on the specific facts of each property!

Great question! I went through this same confusion on my first flip. The 14-month holding period definitely works in your favor for investor classification. One thing that really helped me was creating a detailed contemporaneous log of my intent when I purchased the property. Did you buy it with the intention to flip quickly, or were you open to holding it longer if the market wasn't right? The IRS loves documentation showing your investment intent rather than dealer intent. Since you've been tracking everything meticulously, make sure you're categorizing expenses properly. Things like acquisition costs, renovation materials, permits, and even your mileage to check on the property should all be added to your cost basis if you're classified as an investor. Don't expense them on Schedule C unless you're definitively a dealer. For a one-time flip held over a year, you're almost certainly going to be treated as an investor. Just make sure when you file that you use Schedule D for the capital gain and include all those tracked expenses in your cost basis calculation. The long-term capital gains treatment will be much more favorable than ordinary income rates!
