Tourism Holdings said annual earnings beat its downgraded guidance due to a one-off tax gain in the US.
The rental RV operator said net profit will "comfortably exceed" the top of its $25-$27 million forecast, after its advisers found $1.8m of tax benefits from its US operations.
Excluding the one-off gain, earnings will be at or slightly above the top end of guidance, it said.
"The tax years that the losses were applied to had a higher tax rate than the losses were previously valued at," chair Rob Campbell said in a statement.
Tourism Holdings downgraded its annual earnings guidance twice this financial year, and in June it warned that a potential tax issue in Australia may be more expensive than previously announced.
