Powerball’s jackpot had vaulted the $1.5 billion mark well before Wednesday night’s drawing, promising more extra revenue for state coffers.

Through Saturday’s drawing, which failed to produce a winner for the 19th straight time since Nov. 4, the Connecticut Lottery Corp. had sold more than $31.4 million worth of Powerball and Power Play tickets, generating $12.6 million for the state’s general fund, lottery officials said.

During that span, lottery players won nearly $11.6 million in Powerball prizes.

With tickets selling like, well, Powerball tickets across the country, the Multi-State Lottery Association hiked the jackpot estimate from $1.4 billion to $1.5 billion on Tuesday, putting the value of a winning lump-sum payout at $930 million and raising the possibility that the lump sum would reach $1 billion by the time the drawing took place.

A winner who opted to take $930 million up front rather than annual payments over 29 years could expect to pay nearly a third of it in taxes, according to lottery officials. The federal government would take 25 percent, or $232.5 million, while Connecticut’s share would be 6.7 percent, or $62.3 million.

The winner would be left with $635.2 million.

In Connecticut, where lottery retailers earn a 5 percent commission on ticket sales, the retailer who sells the winning Powerball jackpot ticket — one matching a total of six drawn numbers, including the Powerball number — will receive a $100,000 bonus. Retailers who sell a winning ticket that matches the first five numbers drawn but not the Powerball number receive a bonus of $2,500.

In a state-by-state analysis of lottery revenues, a research group at the State University of New York reported that the country’s 44 state lotteries sold $70.2 billion worth of all kinds of lottery tickets in the 2014 fiscal year. After subtracting prizes, administrative costs and other expenses, the states’ net revenues were around $18.1 billion, 26 percent of sales, the Nelson A. Rockefeller Institute of Government found.

The Connecticut Lottery Corp. funneled $319.5 million in revenue to the state’s general fund in fiscal 2014, a sum that represented about 2 percent of the state’s total tax revenues.

Lottery revenues amounted to more than 5 percent of total tax revenues in three states — South Dakota, Oregon and Georgia — but were less than 1 percent of taxes in 11 states and less than 2 percent in another 12 states, according to the institute’s analysis.
