How much income is allowed before social security is taxable?


It depends on if you are single or married. If you are single you can have "combined income" up to $25,000 of income before your Social Security becomes taxable; if you are married that number is $32,000. "Combined income" is defined as half of your Social Security income, plus any tax exempt income, plus any other income (from investments, pensions, rental property, etc.).
