I have not filed my US tax return. What happens if I don’t file it?
The IRS is taking enforcement steps for those who repeatedly choose not to comply with the law. IRS employees will prepare returns when taxpayers do not file. The returns prepared by the IRS might not give credit for deductions and exemptions a taxpayer may be entitled to receive. Bills will be sent to those taxpayers for the tax due, plus penalties and interest.
People who repeatedly don’t comply with the law are subject to additional enforcement measures.
To prevent problems with the IRS we suggest that your US tax return is filed as soon as possible.
