that almost sounds like you asking people to help you defraud someone (I would say if I wanted to think the worst)

Uh, if you fudged on your taxes, now you gotta pay the price -- no evidence of income. Think about it: if you go to get a loan, they're going to want tax returns. If you say "well, I cheated on my taxes, but here's some great bank statements", the lender is going to get a kick out of that. This is called karma, by the way.

You asked a simple question: your attorney can qualify as an expert and assist in proving your income, whatever it is, since tax records are only one part of the financial picture. Another suggestion: your personal banker.

The answer to this depends upon a lot of variables: 1. Why are you trying to show more income? Are you selling your business and want to establish its value? If so, this is a common problem and the right attorney or business broker can probably help you. I am going to assume this is what your are doing. If so, you need to construct a "pro-forma P&L". 2. Are you trying to show more gross income or net income? If you are trying to show more gross income, then it would seem that you have some unreported income or other problem that is not good. If you are trying to show more net income (this is very common), then I assume that somewhere you have good records of gross income. This obviously depends upon your business, in mine the records would be in the point of sale system. But somewhere you must record receipts. 3. If you start from receipts and then look at your expenditures you can see what expenditures are peculiar to your way of doing business and what expenditures a reasonable hypothetical person would need to run the business. For example, do you do a lot of travel and entertaining that you record as business expenses? Can you make a case that many of those would not be incurred by another person? Do you have the business lease you a car? How many computers, printers, pdas, etc did you buy? 4. These expenses that are not absolutely necessary become "add-backs". A prospective purchaser may or may not agree with all your add-backs, but a prospective purchaser will probably have his or her own business plan. Therefore you will probably create your own pro-forma and the purchaser will too. This is the space around which you will come up with a negotiated value. 5. Most people want to have their cake and eat it too. They want to show as little income as possible until it is time to sell their business, then they want to show as much income as possible.
