Requiremnts: Make necessary assumptions for information not given in the problem but needed to complete the return. The Clarks are employing the same tax return preparer who completed their tax return for the prior year. The taxpayers have substantiation (e.g., records, receipts) to support all transactions for the year. If a refund is due, the Clarks want it applied to next years tax liability. The Clarks do not want to contribute to the Presidential Election Campaign Fund.
