There’s more tax flexibility as a 1099 freelancer and if you have previous work expenses for the year it can offset any income. For example, if you bought a $2k laptop to work with $2k of 1099 income can be offset by the purchase so you pay no state, federal, or payroll taxes. If you are w2 then you can only deduct the amount that exceeds 2% of annual gross income.

Typically w2 is better for the employee. But if you are planning to do a lot of work then getting a 1099 under your LLC or S or C Corp can work out better for a sole owner.
