It compares the most recent estimates, including the amount appropriated by Congress, to the President&#39;s budget. (Source: &#34;Table S-5. <a href="https://www.whitehouse.gov/sites/default/files/omb/budget/fy2017/assets/17msr.pdf" data-component="link" data-source="inlineLink" data-type="externalLink" data-ordinal="6">Mid-Session Review Fiscal Year 2017</a>,&#34; Office of Management and Budget, July 15, 2016. &#34;<a href="https://www.whitehouse.gov/sites/default/files/omb/budget/fy2017/assets/budget.pdf" data-component="link" data-source="inlineLink" data-type="externalLink" data-ordinal="7">FY 2017 Budget</a>,&#34; February 9, 2016. &#34;<a href="https://www.whitehouse.gov/sites/default/files/omb/budget/fy2016/assets/budget.pdf" data-component="link" data-source="inlineLink" data-type="externalLink" data-ordinal="8">FY 2016 Budget</a>,&#34; February 2, 2015. )</p><h3>Revenue</h3><p>The federal government received $3.276 trillion in FY 2016. That&#39;s lower than President&#39;s budget estimate of $3.545 trillion. Income taxes contributed 47%, payroll taxes were 34%, and corporate taxes were 9%. The remaining 10% came from excise taxes, estate taxes, <a href="https://www.thebalance.com/what-is-quantitative-easing-definition-and-explanation-3305881" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="9">interest on Federal Reserve deposits</a>, and other miscellaneous sources.</p><p><a href="https://www.thebalance.com/what-is-tax-freedom-day-3306327" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="10">Tax Freedom Day</a> occurred in late April. That&#39;s how long each taxpayer works to pay for all Federal revenue collected. </p><h3>Spending</h3><p>The government spent $3.876 trillion, slightly less than the President&#39;s budget of $3.99 trillion. That&#39;s because <a href="https://www.thebalance.com/mandatory-spending-definition-programs-and-impact-3305940" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="11">mandatory spending</a> came in lower than the President&#39;s estimate.

Here&#39;s the breakout.</p><p><strong>Mandatory:</strong> The government spent $2.487 trillion on mandated benefits, less than the $2.543 trillion budgeted. This portion of the budget is an estimate, not an appropriation. That&#39;s because Congress mandated the benefit payments when it originally passed the laws that created the programs. </p><ul><li>Social Security -- $911 billion spent ($938 billion budgeted). Payroll taxes fund 100% of the cost.</li><li>Medicare -- $586 billion ($583 billion budgeted). Payroll taxes and premiums fund 57% of the cost.</li><li>Medicaid -- $369 billion ($351 billion budgeted). Paid out of the general fund.</li><li>All other -- $621 billion ($497 billion budgeted). Food Stamps, and Supplemental Security for the Disabled are paid out of the general fund. Unemployment Compensation is partially funded by payroll taxes.

The expected payment is $233, higher than the $223 billion budgeted. </p><p><strong>Discretionary: </strong>The President&#39;s budget was $1.086 trillion. As you can see, Congress didn&#39;t cut much.
