Problem 3-44 (LO. 1, 3, 4, 6) Kantner, Inc., is a domestic corporation with $50,000 of pretax book income. Included in that income are $7,800 of tax-exempt municipal bond interest and $1,700 of entertainment expenses. It's balance sheets for book and tax purposes at the end of the year are as follows: Based on this information, determine Kantner's net Federal deferred tax asset or net deferred tax liability at year-end. Assume a 21% Federal corporate tax rate, no state or foreign taxes, and no need for a valuation allowance. Assume that you are a tax accountant with Kantner, Inc. Your supervisor has asked you to develop a Microsoft Excel workbook to automate as much as possible the current year provision. They would also like the workbook to be structured so that it can be used for the provision every year going forward with minimal input required. They have suggested using separate worksheets to determine current tax expense, deferred tax expense, and the rate reconciliation. The worksheets should require as little numerical input as possible and be linked to avoid requiring the entry of the same information more than once
