Jeffrey Gundlach said an unannounced visit by an Internal Revenue Service agent at his Tampa, Florida office turned out to be a clerical error.
The mistake "does not induce confidence in the system," the DoubleLine Capital co-founder said in a tweet Wednesday evening, his latest complaint aimed at tax authorities.
The agent had showed up for "no legitimate reason," Gundlach had said late Tuesday, without providing further details.
Representatives for DoubleLine Capital didn't respond to requests for comment.
Gundlach moved the main office of his money management arm to Florida after criticizing taxes and the quality of life in California.
The outspoken investor joined a slew of other financiers shifting to the Sunshine State from higher-tax regions such as New York, New Jersey and Illinois during the pandemic.
