Do you manage your taxes, but don't analyze the tax impact? Common problems that good tax advice can avoid
Statements submitted without strategic review
The form is complied with, but it is not evaluated if it is overpaid.
Lack of control in transactions between companies
Failure to correctly record related-party transactions can lead to penalties.
Reactive management before the Treasury
It is answered only when there are problems, it is not prevented.
Not anticipating tax closures
Improvised decisions in December that could have been planned.
Disconnection between taxation and accounting
Without a unified vision, opportunities and efficiency are lost.
Outdated regulations
Tax changes that are not applied in time due to lack of expert follow-up.
