Tax filers with adjusted gross income up to $75,000 for individuals and up to $150,000 for married couples filing joint returns will receive the full payment. For filers with income above those amounts, the payment amount is reduced by $5 for each $100 above the $75,000/$150,000 thresholds. Single filers with income exceeding $99,000 and $198,000 for joint filers with no children are not eligible. Social Security recipients and railroad retirees who are otherwise not required to file a tax return are also eligible and will not be required to file a return.IRS website
