The answer is $6200.00
Based on https://taxfoundation.org/2014-tax-brackets/
The standard deduction single based on the source is $6200. Tax exemptions for singles are up to $52,800. The threshold on this tax is an annual salary of $254,200. Higher salaries would have higher tax deductions. Once a single tax holder enters $376,700 the person would no longer be included for higher exemption because of the gross compensation increase.
