She was also sentenced Monday in Newark to three additional months of home confinement.
The 37-year-old South Orange resident pleaded guilty last year in the case.
During a forceful statement to the judge, Hill explained she had always meant to eventually pay the taxes but was unable to during a period of time when she dropped out of the music business.
Before the sentencing, her attorney said Hill had paid more than $970,000 to satisfy the state and federal tax liabilities.
Hill had faced a maximum sentence of one year each of the three counts. Her attorney had sought probation.
It’s not clear when or where she’d report to prison.
