In estate planning, trusts fall into taxable and nontaxable categories. Taxable trusts operate as independent entities, filing separate tax returns and paying taxes on generated income. Nontaxable trusts, typically with a unified creator and beneficiary, are treated as disregarded entities. Key considerations for taxable trusts include their independent status, the need for an Employer Identification Number (EIN), and strategic income distribution to optimize tax rates. Given the complexities, seeking guidance from a proficient trust attorney is crucial for successful trust establishment and management.
