This is really a question for an accountant, not an attorney, but as general matter, the ways to reduce taxes are:1) To change the timing of payments, so that payments are either accelerated into a year in which you have a lot of tax deductions, so that you can take full use of those deductions; or by spreading payments out over several years, so that in now one year, is your income pushed into higher brackets.2) By characterizing as much of the sale as possible as being "capital gains"--profit from the sale of certain assets, like machinery or intellectual property--which is taxed at a lower rate.3) By making maximum use of depreciation and write-offs of any losses or bad debts.You should sit down with an accountant--not just an income tax preparer, but any actual accountant--to strategize how to structure things for maximum tax benefit.
