The notice of tax arrears, also known as SNOD (Statistical Notice of Deficiency) and 90-day letter, is a statutory notice issued by the IRS to taxpayers.

Some people may worry about whether I will immediately receive the notice of tax arrears as long as I owe tax? no, it isn't.
Generally speaking, the first notice and letter are intended to notify taxpayers to submit the missing tax return and require taxpayers to provide information related to the tax return as a supplement; Or the tax form notified to the taxpayer needs to be audited.
If the taxpayer fails to submit the tax form or fails to submit it according to the requirements of the IRS, the IRS will finally assess the taxpayer's tax liability and issue a notice of tax arrears.
In addition, when the IRS believes that taxpayers intentionally understate their income, want to pay less tax, or have the obligation to declare but do not declare, the IRS will also directly issue a notice of tax arrears.
