The IRS already has your W-2s, your 1099s, your payment reports.
They know what you earned before you even file.
So if you don't file, they will, it's called a Substitute for Return, and it's not done as a favor.
They're not hunting for your deductions or write-offs, just calculating the highest number they can legally charge you.
Why bother? Because the IRS can't collect until they officially assess the tax.
That assessment is the moment "we think you owe" becomes "you owe", and it's what starts their collection clock.
Filing yourself keeps you in control.
