Felicity Huffman will not serve her entire federal prison sentence this month, according to a new report.

The Emmy winner surrendered to authorities on Tuesday to do her time, but she'll only be in the Federal Correctional Institution in Dublin, Calif. for 13 days rather than 14, according to a Federal Bureau of Prisons spokesperson who spoke with Entertainment Tonight.

Huffman, 56, received her sentence last month after pleading guilty in May for her role in the college admissions scandal. The sentence also included 250 hours of community service and a $30,000 fine.

The spokesperson said Huffman was given credit for the remaining day to account for the time she spent in custody following her arrest in March.

"Any part of a day spent in official detention equals one day for credit purposes," the spokesperson explained. "Credit is given for time spent in official detention as a direct result of the federal offense for which the federal sentence was imposed."
