Mortgage insurance paid in 2013 can be deductible as mortgage interest (the deduction is scheduled to expire at the end of this year). However, income limits apply to limit or prevent a deduction.
Advance payment of current tax liability based either on wage withholdings or installment payments of your estimated tax liability. To avoid penalties, you generally must pay to the IRS either 90% of your final tax liability, or either 100% or 110% of the prior year’s tax liability, depending on your adjusted gross income.
