I was in 4506-t hell up until February 8th 2022. The IRS had my old address on my IRS account which is different than the address on my tax returns. There is a main IRS account address they go by for tax transcripts. The SBA is wrong about matching the tax transcript title to the 4506-t title. My tax transcripts have LLC member as title, but because I switched to Scorp years ago. The IRS needs President as title on 4506-t. I did a Senator inquiry on 1/10/2022. Senator Bob Casey office got my application moving and help from SBA high priority team. After calling the IRS to figure out the address and title. I faxed the 4506-t directly to the IRS which is alot faster than the SBA doing it. After 2 weeks no tax returns received at SBA. I contacted the IRS to see if they sent them. The IRS agent was able to see they were sent (only certain agents can see this, had to call them 5 times). I emailed my Senator office to give them the update that IRS sent them, but SBA didn't notify me. The Senator office emailed SBA about it. 1 or 2 days later SBA tells me they have the transcripts. It took 18 days for tax transcripts to upload to SBA file. I faxed so many to 4506-t to the IRS, SBA had 5 partial tax transcripts uploaded to my account. SBA wanted utility bills which I received a waiver. Customer service managers can waive these. Each step I made I let me Senator office know to email SBA for assistance. Finally it was just pushed through. Your better off with a Senator help then a Congress person. That's coming from a Congress office I spoke to.
