I had a few minutes and thought I would get right back to you. (sometimes my days are light!!)
The only thing I can think to do to find this UCC document would be to go to this site:
You would then go to: SOS Direct and search for the company there. (You could sign in by getting a "temporary login" if you did not want to get a permanent login.)
That is the best advice I can offer.
Unfortunately - I do not know of any way to look this up online. You can usually look up a companies corporate filings on their state`s Secretary of State web site online - if they are incorporated in their state or an LLC - but you will not find their EIN number listed in those document filings.
At year end, you would not be able to file a 1099 unless you had the EIN number or the owners social security number. You could go to www.IRS.gov and browse their site. They might have some information out there about how to handle this situation. Or you might want to call the IRS: 800-829-4933 and ask a representative there how you can handle this. You can usually ask questions anonymously if you prefer.
When selling services only - you usually do not need a Sales and Use tax ID number. However, if you plan to sell products, you will use the Sales & Use tax ID number to purchase products for re-sale - usually from a wholesaler - without having to pay sales tax. You then would sell these same products retail and collect your states sales tax from your customer. The sales tax you collect then gets remitted to the state of Maryland. It is not an expense to your business because you have to turn it over to the state. You should contact the Comptroller of Maryland at:
Additionally, if you have incorporated a business, you probably should get a Federal Employer Identification Number (FEIN). You state that you are the only employee. This sounds to me that you have an S Corporation. A shareholder of an S Corporation is considered an employee and needs to be put on payroll. You would use your FEIN number for all payroll tax reporting as well as year end tax filings. If you were an unincorporated entity - such as a sole proprietor - then you could get by with using your social security number rather then getting an EIN number. You can go to www.irs.gov and apply for an EIN number online.
If I can clarify anything for you, please let me know!
Correct your LLC is going to be taxed as a sole proprietorship if it is a Single Member LLC - which you have indicated. This is the IRS default classification for Single Member LLC`s - although you could have elected to be taxed as a coroporation. You would have had to have filled out a special election to do that. Your post does not indicate that you elected to change your entity status for tax purposes.
