Understanding Federal Sentencing: A Comprehensive Guide

Federal sentencing is governed by three layers of authority: the advisory United States Sentencing Guidelines, the mandatory statutory factors in 18 U.S.C. § 3553(a), and any statutory minimum or maximum set by the offense of conviction.

What the Guidelines Are

The United States Sentencing Guidelines are rules and policy statements published by the United States Sentencing Commission, an independent commission in the judicial branch established by the Sentencing Reform Act of 1984. A court begins every federal sentence by calculating the applicable guideline range.

How a Guideline Range Is Calculated

• Base offense level. Each guideline assigns a starting level for the offense of conviction.
• Specific offense characteristics. Adjustments for loss amount, victims, weapons, role in the offense, and other factors.
• Adjustments. Acceptance of responsibility, obstruction of justice, and other Chapter Three adjustments.
• Criminal history category. Prior sentences produce criminal history points that place the defendant in one of six categories.

The Statutory Factors

18 U.S.C. § 3553(a) directs the court to impose a sentence “sufficient, but not greater than necessary” to comply with the purposes of sentencing, and to consider the nature and circumstances of the offense, the history and characteristics of the defendant, and the need for the sentence to reflect the seriousness of the offense, afford deterrence, protect the public, and provide correctional treatment.

Advisory, Not Mandatory

Since United States v. Booker, 543 U.S. 220 (2005), the guidelines are advisory. The court must calculate the range, but may sentence outside it — a departure under the guidelines or a variance under the § 3553(a) factors.
