Best Partnership Tax Return Software (Form 1065) in 2026

TurboTax is well-suited for businesses required to file Form 1065, including partnerships and multi-member LLCs taxed as partnerships. It handles the full partnership filing package from preparing the Form 1065 and producing accurate Schedule K-1s for each partner, which are required for partners to correctly report their share of income, deductions, and credits.

It offers both assisted tax preparation and full-service tax preparation, making it the only provider in this comparison to offer both options. Certain plans also include audit support, meaning help responding to IRS notices, along with direct communication with the IRS when issues arise.
