No, the IRS does not catch all mistakes on tax returns, but it uses automated systems to identify common errors like mismatched income, missing documents, or math issues.

Although the IRS often finds and corrects errors during processing, there are certain situations in which you may need to file an amended return to correct an error or make other changes to your return.

The IRS and Irrevocable Trusts
When you put your assets into an irrevocable trust, they no longer belong to you, the taxpayer (this is different from a revocable trust, where they do still belong to you). This means that generally, the IRS cannot touch your assets in an irrevocable trust.
