Depending on the amounts, the DR-15 is filed/paid either monthly or quarterly. It depends on the amounts which I don't know off hand. The late filing/late payment penalties can be a bit high to. I would suggest for your first time to seek the services of a tax professional to ensure you get started on the right foot. Then if you want ande you're comfortable doing it yourself, you can do so with future filings/payments to the state.
You'll also find it's a whole lot simpler, faster and more efficient to just deal with it on-line instead of dealing with the hassle of paper forms every reporting period.
