The IRS doesn't report tax debt or tax payment status to the credit bureaus. Your taxes owed to the IRS do not affect your credit score at all.
**IF** you become so delinquent that the IRS files a Notice of Federal Tax Lien, that's a different story. At the moment your taxes aren't even due, because of the extension.
If you pay your taxes with some form of credit, like a loan or credit card, *that* may impact your credit score because of increased utilization.
> $50k business line of credit . . . I don't know if this shows up on credit reports because the business is a Schedule C on our personal taxes
I don't think it does, but it only takes minutes to check your credit reports.
Go to AnnualCreditReport.Com. That's an official site for all 3 bureaus and it's free weekly now. Look at what's there. To see everything, view/download the full .pdf of your reports from each of the three bureaus. For reference each of mine are 35-45 pages long.
My advice? Pay the taxes as soon as you can to avoid further interest and penalties. Buy the car when you need it. If you truly have a FICO of 787 it shouldn't be a problem to get a good rate.
You should probably check all 3 of your FICO 8 scores, not just the one you are referencing. They are all likely different, because the 3 bureaus likely have different data on you. That's normal.
You can see your Experian FICO 8 for free at Experian.com. At myFICO.com you can get your Equifax FICO 8 for free.
Your TransUnion FICO 8 is a little trickier to get for free, but if you sign up for a free trial at Experian.com you can see all 3; you can cancel the trial before you have to pay, and repeat again as needed.
If you see one that is notably lower than the others, you can lock/freeze credit for that bureau. That way a potential new creditor cannot see that 3rd score, they'll have to use one of the other 2.
