Andrew Sullivan, 35, faced three charges when he appeared at the city’s crown court.
Sullivan pleaded guilty to one offence of dishonestly failing to notify the Department for Work and Pensions of a change in circumstances.
He also admitted two counts of making a dishonest representation for obtaining benefit.
These offences are said to have been committed between April 2011 and May 2012, when Sullivan failed to declare to the authorities that he had capital over the prescribed limit.
Kim Whittlestone, prosecuting, told the court: “He had £30,000 in savings during the relevant period.”
Had Sullivan, of Ellesmere Way, Morton, officially declared that was the case he would not have been entitled to claim, Miss Whittlestone confirmed.
In total, his eventual overpayment of employment and support allowance, council tax and housing benefit amounted to £36,959.06.
Judge Peter Davies adjourned the case until January 25 for sentence.
