You need to get the help of an experienced accountant. You have made a big mistake. This is why you should never try to calculate your taxes by yourself. I also use the services of a freelancing accountant to calculate my taxes. Firstly, I decided that I could learn to calculate my taxes and learn how to work with Quickbooks. It is bookkeeping software. I found out about it on playlouder.com. I have made several mistakes, and then I decided that it is better to find an experienced accountant to calculate my taxes.
