Retirement generally means living on a budget, fortunately there ares places to live where that's easy. The state of Pennsylvania is becoming a talked-about option for this population, because of its affordability, more relaxed pace of life, excellent healthcare, and moderate weather.

Pennsylvania is also known as being tax-friendly for retirees. It is one of the only two states in the country that does not tax retirement income. Public and private pension income is 100 percent tax exempt; IRAs, 401(k) accounts, and Social Security checks are also tax free here. The state also boasts a flat tax rate of 3.07 percent, which is the lowest in the U.S.

But that’s not all, the state sales tax is 6 percent (also one of the lowest rates in the nation). Food, clothing, and all non-prescription and prescription drugs are also tax exempt.

55places.com lists 167 age restricted and active lifestyle communities in Pennsylvania, and it is not surprising that the prices drop the further you get from large cities like Philadelphia. When looking for homes for sale in Pennsylvania, it can make financial sense to spread your wings and look at some of the more budget-friendly areas.
