Need a US tax ID but do not have a Social Security number?

An Individual Taxpayer Identification Number is required for anyone who needs to file a US tax return but is not eligible for a Social Security Number. A mistake on the application delays your filing, holds up any refund, and creates friction with the IRS that can take months to unravel. Dimov Partners handles ITIN applications and renewals as a certified acceptance agent, which means we can certify your documents so your passport never has to leave your hands.
