Attorney General Martha Coakley and her husband reported an adjusted gross income of nearly $215,000 in 2013, consisting almost entirely of Coakley's salary of about $130,000 and her husband's pension of more than $83,000.
Coakley is the latest of a series of candidates for governor to release at least three years of tax returns.
Republican Charlie Baker, fellow Democrats Steve Grossman and Don Berwick, and independent candidate Evan Falchuk have also released tax returns.
Coakley and her husband, retired Cambridge police Deputy Superintendent Thomas F. O'Connor, filed jointly. Their total income has changed little over the three years.
The couple reported paying more than $37,000 in federal taxes in 2013 and nearly $7,000 in state taxes.
They also reported giving more than $4,000 to charity in 2013.
