I need to compute the book income of a Company A:

one of the information is that the deferred revenue account was established because company A received full payment the previous year on a contract for services, 50% that company A performed this year and 50% of which company A will perform next year. company A elected a tax deferral of this gross income under RevProc 2004-34.

the amount that i have in the Balance sheet (end current year) for deferred revenue is 200, so in this case those 200 will increase my book income, and it will be reduce for taxable income?

this is the balance sheet:

ASSETS Cash $ 1,500 Accounts receivable 1,100 Inventories 1,400 Property, plant & equipment, net of depreciation 2,000 Investment land 2,550 Notes receivable, long term 210 Deferred tax assets 40 All other assets 2,750 Total $ 11,550 LIABILITIES and SHAREHOLDERS' EQUITY Accounts payable $ 250 Taxes payable 725 Deferred revenues 200 Accrued pension liabilities 3,250 Notes payable, current 175 Notes payable, long-term 1,505 Deferred tax liabilities 65 Common stock 1,000 Retained earning 4,380 Total $11,550
