Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter E— Accounting Periods and Methods of Accounting › Part II— METHODS OF ACCOUNTING › Subpart A— Methods of Accounting in General › § 446
Figure taxable income using the accounting method you normally use in your books. If you have no regular method or your method doesn't clearly show income, the IRS can require a method that does. You may use the cash method, an accrual method, other methods allowed by law, or a permitted mix of those methods. If you run more than one business, each business can use a different method. If you change your regular method, you must get the IRS’s permission before using the new method to compute taxes. If you change without filing for permission, the lack of IRS approval cannot be used to avoid or reduce any penalty or added tax.
