The IRS is probably somewhat backlogged with amended returns right now. In my experience, which is admittedly limited to just my own situation last year, it took almost 4 months for my amendment to process. You might want to consider pulling your tax transcripts if possible - sometimes they show movement even when the Where's My Amended Return tool doesn't update. I saved myself a lot of worry (and potentially paying for professional help) by checking my transcripts regularly.

Have you tried checking your tax account transcript instead of just the WMAR tool? Sometimes the transcript shows activity even when the amendment status tool doesn't update. And have you received any letters or notices in the mail? The IRS often communicates by mail rather than updating their online systems, especially when they need additional information, don't you think?

Think of the DDD like a package delivery date - the IRS is like the shipping company that's handed your money to the delivery driver (the banking system). Sometimes the driver arrives early in the morning, sometimes late afternoon - but they're aiming for that specific delivery date. Your cycle code 0405 is like the routing number on the package - it tells you which truck your refund is on, but not exactly when that truck will arrive at your specific address. In most cases, the money arrives right on the DDD, but occasionally it shows up a day early if your bank processes incoming transfers quickly.

Did you verify if your business expenses triggered any additional review? According to the IRS processing guidelines (https://www.irs.gov/businesses/small-businesses-self-employed/business-expenses), certain Schedule C deductions can trigger additional verification steps. Have you checked your Account Transcript to see if there were any TC 420 codes that might indicate a review was conducted before issuing your DDD?

You might want to check if your refund was reduced for any reason. If the IRS adjusted your refund amount, this can cause delays as SBTPG has to reconcile the difference between what they expected and what they received. This happened to me when they disallowed a credit I claimed - the amount changed, causing a 5-day delay while SBTPG adjusted their records according to Treasury Regulation §301.6402-2.

I would caution about one thing that happened to me last year: Credit Karma's tax preparation service was acquired by Cash App Taxes, and during that transition period, some refunds experienced unusual delays. While your situation sounds like a normal processing delay, it's worth keeping in mind that sometimes system changes or updates on their end can affect processing times. If it goes beyond 3-4 business days, I'd definitely start making calls to both SBTPG and your bank.

Back in 2022, I had this exact scenario. My WMR showed processing for 3 weeks while my transcript showed nothing. Then suddenly my transcript updated with a 570 code (additional account action pending) followed by a 571 (resolved) the next day. My refund was deposited exactly 8 days after the transcript first updated. The IRS processing pipeline has multiple stages, and the transcript database is just one of several systems that need to sync up.

According to Internal Revenue Manual 21.4.1.3, the Transcript Delivery System (TDS) and the Where's My Refund tool pull from different databases that update on different schedules. The WMR tool updates from the Master File and ISRP systems, while transcripts are generated from the IDRS. During peak filing season, these systems can be 3-5 business days out of sync with each other. It's frustrating but unfortunately completely normal.

I successfully navigated this exact situation last year! I discovered I was enrolled in Tax Max through my employer without fully understanding what I signed. After some initial panic, I called my HR department who connected me with our Tax Max representative. I explained I wanted to receive my refund directly and they provided a form to opt-out for future years. For that tax year, I filed my return through a different tax preparer (not the one associated with Tax Max) and simply entered my own bank information on my tax return. The IRS used the direct deposit info from my tax return, not what was on my W2. My refund came directly to me with no issues or delays!

Did you check if there was a refund advance option you might have signed up for during onboarding? Sometimes these services offer to give you part of your refund early, but they change your direct deposit info to get paid back. Did you get any money already before filing your taxes?
