How long until the IRS comes after me?

The timeline for the IRS to take action can vary widely depending on your specific situation, such as whether you owe taxes, if you've filed your returns, or if you're under audit. Generally, the IRS can begin collection actions, such as sending notices or levying bank accounts, within a few months after a tax return is due and not paid. If you ignore communications from the IRS, they may escalate their actions within a year or so. It's best to address any tax issues promptly to avoid further complications.
