How many exemptions can I claim after I buy a house.?
Unless you expect to have a large amount of other itemized deductions, such as medical expenses in excess of 7.5% of your income, or a large amount of charitable contributions, or property taxes, you can only claim one exemption. The worksheet on the W-4 form will tell you how many exemptions you can claim. If you claim more exemptions than you’re entitled to, you can be fined and assessed tax penalties.
