Health Insurance Deduction Reduces Self Employment Tax  In 2010, eligible self-employed individuals can use the self-employed health insurance deduction to reduce their social security self-employment tax liability in addition to their income tax liability. As in the past, eligible taxpayers claim this deduction on Form 1040 Line 29. But in 2010, eligible taxpayers can also enter this amount on Schedule SE Line 3, thus reducing net earnings from self-employment subject to the 15.3 percent social security self-employment tax.

Premiums paid for health insurance covering the taxpayer, spouse and dependents generally qualify for this deduction. Premiums paid for coverage of an adult child under age 27 at the end of the year, for the time period beginning on or after March 30, 2010, also qualify for this deduction, even if the child is not the taxpayer’s dependent.

First-time homebuyer credit You must meet the required deadlines to be eligible to claim the credit.  You must have bought — or entered into a binding contract to buy — a principal residence on or before April 30, 2010. If you entered into a binding contract by April 30, 2010, you must have closed or gone to settlement on the home on or before Sept. 30, 2010.   Because of the documentation requirements for claiming the credit, taxpayers who claim the credit on their 2010 tax return must file a paper — not electronic — return and attach Form 5405, First-Time Homebuyer Credit and Repayment of the Credit, and a properly executed copy of a settlement statement used to complete the purchase.

Taxpayers who claimed the first-time homebuyer credit for a home bought in 2008 must generally begin repaying it on the 2010 return. In most cases, the credit must be repaid over a 15-year period. Many of those affected by this requirement received reminder letters from the IRS.

Standard Mileage Rates for 2010 The standard mileage rate for business use of a car, van, pick-up or panel truck is 50 cents for each mile driven. The rate for the cost of operating a vehicle for medical reasons or as part of a deductible move is 16.5 cents per mile. The rate for using a car to provide services to charitable organizations is set by law and remains at 14 cents a mile.
