On-site - A tax preparer will come to you at your home, office or even on your lunch break. I will have everything needed to complete your return during your appointment. Off-site - Email, fax or mail in your paperwork and a tax preparer will complete your return within 3 business days (provided all required information is available). Which ever method you choose there is no trekking back and forth to the tax office. And you can be sure your return is being completed timely and accurately.
