As an individual taxpayer, and as a business owner, you will often have the option of completing a taxable transaction by more than one method. The courts strongly back your right to choose the course of action that will result in the lowest legal tax liability. In other words, tax avoidance is entirely proper.

Although tax avoidance planning is legal, tax evasion — the reduction of tax through deceit, subterfuge, or concealment — is not. Frequently, what sets tax evasion apart from tax avoidance is the IRS's finding that there was some fraudulent intent on the part of the taxpayer. The following are four of the areas most commonly focused on by IRS examiners as pointing to possible fraud:

• A failure to report substantial amounts of income, such as a shareholder's failure to report dividends, or a store owner's skimming from the cash register without including it in the daily business receipts.
• A claim for fictitious or improper deductions on a return, such as a sales representative's substantial overstatement of travel expenses, or a taxpayer's claim of a large deduction for charitable contributions when no verification exists.
• Accounting irregularities, such as a business's failure to keep adequate records, or a discrepancy between amounts reported on a corporation's return and amounts reported on its financial statements.
• Improper allocation of income to a related taxpayer who is in a lower tax bracket, such as where a corporation makes distributions to the controlling shareholder's children.

How a tax plan works. There are countless tax planning strategies available, particularly if you own a small business. Some are aimed at your individual tax situation, some at the business itself. But regardless of how simple or how complex a tax strategy is, it will be based on structuring the transaction to accomplish one or more of these often overlapping goals:

• reducing the amount of taxable income
• reducing your tax rate
• controlling the time when the tax must be paid
• claiming any available tax credits
• controlling the effects of the Alternative Minimum Tax
• avoiding the most common tax planning mistakes

In order to plan effectively, you'll need to estimate your personal and business income for the next few years. This is necessary because many tax planning strategies will save tax dollars at one income level, but will create a larger tax bill at other income levels. You will want to avoid having the "right" tax plan made "wrong" by erroneous income projections. Once you know what your approximate income will be, you can take the next step: estimating your tax bracket.
