The IRS is expected to release more information soon for veterans and SSI recipients about how to file a simplified tax return for the purpose of getting the stimulus rebate. In the meantime, TurboTax has partnered with the IRS to help individuals like SSI recipients and veterans register for the stimulus payment. You'll need to create an account with TurboTax at its stimulus registration page, but it's free. Once you're logged in, you'll answer a few questions so that TurboTax can determine your filing status, your mailing address, and your direct deposit banking information, if applicable.
