Tax Information Form Error - Duplicate TIN Matching Request


The IRS defines TIN as Taxpayer Identification Numbers.  TINs are either an individual's Social Security Number (SSN) or an organization's Employer Identification Number (EIN).

The IRS defines a "duplicate" as either attempts with exactly the same TIN, or exactly the same Name, plus the same first five TIN digits.  The IRS does this to prevent their TIN Matching service from being used inappropriately.

ISS is only allowed a certain number of "bad requests" per day across all our users so continued errors in submissions will cause you to not be able to complete this process today.  If that occurs, you will have to return tomorrow and try again.
