The nine include former Toon striker Michael Chopra and jockey Andrew Heffernan.
Chopra and four others have been charged with offering bribes to Heffernan, a former British licensed jockey now riding in Australia.
Three other people have been charged with other breaches of the rules of racing, the BHA have announced.
Paul Scotney, the BHA's integrity, compliance and licensing director, said: "The charges BHA has issued are the result of a long and complicated investigation. This process has taken significant time and resources.
"However, investigations such as these are very similar to fraud investigations and as such are complex and time consuming.
"Furthermore, we encountered difficulties in obtaining telephone records from certain individuals who refused to co-operate. This resulted in us having to make a number of applications to the High Court for orders against their mobile telephone service providers for disclosure of the relevant records.
"We hope that the announcement demonstrates our commitment to deterring and detecting wrong-doing and taking action against those who we believe to have breached the rules.
"However, racegoers and those betting on British Racing should be reassured that instances of this nature are extremely rare and that the overwhelming majority of races are free of suspicion."
28-year-old Chopra left Newcastle and eventually showed his true colours signing for the "great unwashed from the Wear".
All face bans from involvement with racing for several years if the charges are found proven.
The charges relate to a period between November 2010 and March 2011.
In November of 2011, Chopra revealed he had gambled away up to £2million and had checked into the Sporting Chance Clinic to address his addiction.
Chopra said then: "Your first bet's your worst bet. As the years have come along and I've earned more money I've started to gamble more.
"I was gambling up to £20,000 a day at times. As soon as I'd step over the white line I would focus on football - but as soon as I got to the dressing room I would check my phone to see if I'd won.
"In my first season at Cardiff I had a gambling debt from when I was at Newcastle. I had to leave Cardiff and sign for another team to pay that debt off. I have probably lost between £1.5m and £2m on gambling."
