The Homebuyer Credit was a valuable tax incentive available to individuals who purchased a primary residence in the United States between April 9, 2008, and April 30, 2010. The credit amount varied depending on the purchase year and the buyer's situation. For 2008 purchases, the maximum credit was $7,500 or 10% of the purchase price, while for 2009 and 2010 purchases, it was $8,000 or 10% of the purchase price. Repeat buyers who had owned a primary residence for at least five consecutive years in the eight years leading up to the purchase date were eligible for a reduced credit of $6,500 or 10% of the purchase price. The credit was subject to income limits and was phased out at higher income levels. Additionally, the purchase price of the new primary residence could not exceed $800,000. The credit was fully refundable, meaning it could be used to offset regular tax and alternative minimum tax liabilities, with any excess amount refunded to the buyer in cash. It's worth noting that credits for 2008 purchases were required to be repaid over 15 years, starting in 2010, while credits for 2009 and 2010 purchases did not need to be repaid. Buyers could claim the credit on their tax return for the previous year, and certain military service members were eligible for liberalized rules.
