An ITIN is the taxpayer's personal identification number that helps individuals who do not have social security to comply with tax laws in the United States.

When you apply or renew your ITIN number with us, you do not have to send your original documents to the IRS, we certify them and in that way you eliminate the probability of losing your documentation.

Your ITIN may expire before filing your tax return. All ITINS not used on a federal tax return at least once in the last three years will expire on December 31 of the current year. Additionally, all numbers that were assigned prior to 2013 and have not yet been renewed will also expire at the end of this year.

People who wish to obtain or renew an ITIN must bring the following original documents:
