LO7 Art is in the 28% marginal tax bracket for 2010. He owes a $10,000 bill for business expenses. Because he reports taxable income on a cash basis, he can deduct the

$10,000 in either 2010 or 2011, depending on when he makes the payment. He can pay the bill at any time before January 31, 2011, without incurring the normal 8%

interest charge. If he expects to be in a 33% marginal tax bracket for 2011, should he pay the bill and claim the deduction in 2010 or 2011?
