Election to deduct certain preproductive period expenses.
If the preproductive period of any plant you produce is more than 2 years, you can elect to currently deduct the expenses rather than capitalize them. But you cannot make this election for the costs of planting or growing citrus or almond groves incurred before the end of the fourth tax year beginning with the tax year you planted them in their permanent grove. You are treated as having made the election by deducting the preproductive period expenses in the first tax year for which you can make this election and by applying the special rules, discussed later.
