More Than Paperwork: ITIN Assistance From an IRS-Authorized Firm
What our USA ITIN service covers
An ITIN (Individual Taxpayer Identification Number) is the number the IRS issues when you need to file or report U.S. taxes but aren't eligible for a Social Security Number. Foreign investors, nonresident spouses, overseas LLC owners and visiting researchers all run into this requirement.
Getting the number is mostly paperwork, and paperwork is where applications fail. A wrong reason code, an expired document or a missing tax return can send your application back weeks later. We handle the details: we confirm you need an ITIN, choose the correct reason on Form W-7, verify your documents, assemble the package with your tax return or exception paperwork, and mail it to the IRS.
We help with first-time applications, renewals of expired ITINs, and ITINs for spouses and dependents listed on the same return. The IRS reviews every application and makes the final decision. Our job is to make sure what it receives is complete and correct.
What You Can Do With a US ITIN
Earning U.S. income without a Social Security Number doesn't remove your filing obligations. An ITIN is how the IRS identifies you on a return, and it comes up in more places than most people expect.
File a U.S. federal tax return
If you have rental income, a share of U.S. business profits or other income the IRS taxes, you need a taxpayer number to file. An ITIN fills that role when an SSN isn't available.
Claim back over-withheld tax
U.S. payers often withhold tax from income paid to foreign persons. Filing a return with your ITIN is how you claim any refund you're owed. The IRS decides the amount after reviewing your return..
Open a U.S. Bank Account
An ITIN can help you meet the taxpayer identification requirements of certain U.S. financial institutions. Syntax Solutions helps you obtain an ITIN so you can explore bank account and credit application options, subject to each institution’s eligibility requirements.
Claim Dependents on Your Return
Dependents who can't get an SSN need an ITIN to appear on your return. Some credits, including the Child Tax Credit, require an SSN, so we'll explain what your dependents can and can't qualify for.
Report income from a U.S. LLC or investment
Foreign owners of U.S. LLCs and partnerships, and nonresidents selling U.S. property, may have a filing requirement. An ITIN can also be needed to claim reduced withholding under a tax treaty.
Build a U.S. tax history
Each return filed under your ITIN adds to your U.S. tax record. Some banks and lenders accept an ITIN for accounts or loans. That's their policy, not an IRS rule, so check with the institution first.
