Tax Guide for self employed and small businesses?

[Rich Hupper]

HI BP

I am lost. I have been self employed for many years and recently now filing taxes for a real estate trust I operate. I do not understand the relationship between tax returns, borrowing money from banks, and limiting the taxes you pay to the government. I was fortunate enough to be able to save up and buy my home with cash but I am now trying to guarantee loans and everyone denies me.  The trust I run apparently is not credit worthy either despite two years of tax returns. 

Does anyone have a guide for self employed people or small businesses that explains the ins and outs to taxes so you can reduce tax liability, but also get access to loans from banks? The banks all tell me that my trust and my personal returns do not show enough cash flow but they do not elaborate beyond that.

Thank you
