If you were on an antibiotic for an infection, you may donate if your antibiotics course was completed three days before donation and you are symptom-free. In some cases, low-dose antibiotics for acne and other long-standing conditions may be acceptable.
TIN to use on W9 when Single Member LLC/Disregarded entity. 2. I own a state-classified LLC company and also have an EIN for the business, which was filed on an SS-4 form (Rev. December 2001) as a Type Other and noted disregarded entity. On the SS-4 form the Legal Name field is Company LLC, which matches the state registered name.
If a company has already sent you a W-2 form or 1099, then you may have their TIN already. Look for fields that contain taxpayer identification numbers, but be careful that you aren't using state or local EINs which may be different. Note: There are also online services that catalog EIN numbers and verify numbers.
