Tax1099 enables an easier and better way of verifying TINs through TIN Matching or TIN Lookup. Tax1099 is a digital regulatory reporting enabler that provides a variety of TIN verification services for you. We offer real-time TIN Matching which features Bulk TIN Checks.

You enter or import your vendors the same way you do to create your 1099s. Select ‘TIN Match’ on the user dashboard and our dynamic platform takes care of the rest. You get an ‘Accepted’ or ‘Rejected’ status for each match requested. The generated results can be accessed anytime through your account.

The IRS validates the TIN /Tax ID Verification /Tax ID Matching in their database when you file a 1099 return. When the IRS receive a TIN/name combination that doesn't match their records, they issue a CP2100 or CP2100A notice. This means the Payer has to issue a B-notice to the Recipient.

Later, you may receive a penalty notice if the TIN discrepancies are not fixed.

The penalties for TIN mismatch can be up to $260 per occurrence. Even for a small filer, a few of these notices will add up to an amount you don't want to pay. The largest penalty settled in the recent history amounts to $3,000,000 with a maximum limit for small businesses.

Being proactive and using an online TIN Match service can help you and your clients avoid these penalties. Use the IRS EIN Lookup tool to check the TIN and name before issuing payment to ensure vendor tax compliance. A TIN Check also encourages the vendor to comply since they know you won't pay until they furnish the tax details.

When the IRS rejects your TIN Match request, you should follow up with the vendor to confirm the information. Collecting a W-9 is the proper way to do this, but you may have already collected a W-9 from the vendor.

In such a case, it may be a good idea to call or email the person who completed or prepared the form. Often, there is confusion over what name to enter on the name lines of the W-9 form.

When vendors provide incorrect or inaccurate information, they aren't trying to get away with something (usually). They just don't know what goes where.

For clarification, Line 1 on the W-9 form is for the taxable entity name. This could be the individual's name if they operate a sole-proprietorship or single-member LLC. The IRS actually prefers these entities to enter the SSN, but will accept the ElN as well.

Line 2 on the W-9 form is for a business or entity name. This is where the "doing business as" name belongs.

The IRS has accelerated its inspection of filers in the last few years. Using tools like Tax1099 TIN Lookup or TIN Check helps you stay compliant. Proactive Tax ID Lookup is something the IRS recommends. The IRS also acknowledges your efforts to furnishing the most accurate tax information when issuing a notice or monetary penalty. TIN Checks help you prevent being penalized in the first place

We often see vendors provide a Doing Business As or DBA name instead of their legal entity name when completing the W9. The IRS will only recognize the legal entity name that matches the TIN associated with it. Make sure your vendors supply their legal entity name to you.

The TIN Match costs $1.00 per request to match a TIN/Name combination with the IRS database.

Ideally, you will check the TIN before you e-file. Once your vendor data is loaded or entered, you can go to Manage Recipients to check the TINs either individually or in bulk. If you are pushing the deadline to send forms to your vendors, you can use the TIN Match at checkout. Be sure to schedule the e-file to occur by the e-file deadline of March 31st. That will allow you time to receive the TIN Match results and correct any mismatches before the e-file occurs.
