Is there any way to beat wage garnishment?

Yea do work under the table or side jobs were taxes aren't paid. Or move out of the country.

Increase your federal with holdings on your W4,

There is a place for making additional with holding. Increase it until your 'disposable income' (income after taxes are with held) is less then 30 times minimum wage ($7.25) per week of pay.

They can't garnish is wage below that level.

You'll get it back when you file for your return.

Don't put your tax refund in a bank account, that they can garnish. (see about a Delaware bank account)
