Tax HELP!!

In the Cali, USA - Where can I find the charts of formulas to figure out how much Social Security and Medacal I need to pay quarterly.

What IRS docs do I need to figure my state/fed taxes quarterly?

I hope this helps - I generally work with Canadian tax returns, so this is hardly my area of expertise - but, trying to help none the less.

Try searching that site for the info that you need. I would suggest talking with an accountant, because you can be penalized for not filing properly or underpayment. If you'd rather not take on that expense, you might want to consider checking out some portable employer of record organizations. You might actually end up paying less in taxes that way, too.
