A seasonal tax preparer does income tax preparation for clients during tax season each year, usually January 1 through April 15. They may have to complete a tax preparation training course before taking on clients for an employer, even if they have some prior experience. A seasonal tax preparer consults with clients about their year in finances, including employment income, inheritance and investments, charitable donations, whether they have dependents, and other factors that impact taxes. After gathering all the necessary documents, a preparer submits tax returns on behalf of their clients.
