Get your taxes done using TurboTax

PA 40 ES is for estimated tax payments.  You might get this form if you owed state taxes this year, as you are suppose to withhold enough taxes to cover your tax due throughout the year.  When you don't, then you need to make estimated payments.  You might also get this form if you have business or 1099-MISC income as people with those income usually need to make these estimated tax payments.
