Individual US tax filing (1040 and 1040NR)

Filing your tax return is essential for all US Citizens and Green Card holders. With the help of our team, you can minimize your late filing penalties, avoid a reminder from IRS, maintain your status and benefits, and provide your tax information and copy of tax returns where needed.

Past-due returns incur two types of penalties: failure to file and failure to pay. It is important to act as early as possible to begin settling any dues to the IRS. At RKB, we can help estimate potential failure to file and failure to pay penalties that are to be incurred by clients. If you have unfiled US tax returns, you may be eligible to file those delinquent tax returns under the Streamlined Filing Compliance Procedures, and you will not be subject to failure-to-file and failure-to-pay penalties.
