The right tax software simplifies Form 1065 preparation. Key features of the best tax software for Form 1065 include a tax calculator, an accuracy guarantee, seamless data import, and a deduction maximizer. Here are my top picks for the best partnership tax software:

ProviderBest forStarting price
TurboTaxPartnerships needing expert help with Form 1065$0-$139 per filing
ProConnect Tax OnlineTax pros wanting online software$3,700 per year
TaxAct ProfessionalTax pros preparing unlimited returns$109.99 per filing

To determine the best tax software for preparing Form 1065 partnership returns, I focused on how each platform addressed the unique complexities of partnership taxation.

  • Compared DIY, assisted, and full-service options. I evaluated whether each software supported self-prepared returns, offered live assistance from tax professionals, or provided full-service filing to assess flexibility and support across different experience levels.
  • Evaluated pricing models for different user types. I compared per-return pricing with flat-rate unlimited options, factoring in cost per filing as well as additional fees for state returns, extra users, and upgrades.
  • Assessed QuickBooks and ecosystem integrations. I focused on whether each platform integrated with QuickBooks Online or Desktop, since many users rely on QuickBooks for bookkeeping.
  • Reviewed workflow and document handling capabilities. I examined client portals, e-signature support, document request automation, and integration with practice management systems like TaxDome, which are especially important for collaborative Form 1065 preparation.
  • Analyzed ease of use and support quality. I considered interface intuitiveness, learning curve, available support channels, and user feedback, including reviews that referenced depreciation handling and audit-related assistance.

Frequently asked questions (FAQs)

ProConnect Tax Online and TaxAct Professional both support capital account tracking under multiple bases and include the IRS-approved transition tools for legacy conversions to tax basis (the IRS-required method). TurboTax, however, assumes tax basis as the default and provides less flexibility in capital tracking methodology.

TaxAct Professional includes questionnaires and checklists that help you identify state-level filing obligations, but the actual creation of composite returns and withholding forms may require manual adjustment. ProConnect offers built-in compliance, but it still doesn’t automate composite return filings for all states. Meanwhile, TurboTax does not support composite return filings or withholding calculations for partnerships; those must be done manually outside the software.

You can prepare and file Form 1065 manually, but using dedicated tax software can streamline the process, help minimize errors, and ensure compliance with tax laws. Tax software often provides step-by-step guidance, automated calculations, and error checks, which saves time and effort compared with manual preparation.

It is uncommon to find completely free software specifically designed for Form 1065. Partnership tax returns tend to be more complex, requiring advanced features and support. However, some tax software providers may offer free versions or trials with limited functionality.

It depends on your business needs. If you want tax pro assistance and assisted or full-service tax preparation, TurboTax is an excellent choice. If you have unlimited returns, I recommend TaxAct Professional. Meanwhile, I have identified ProConnect Tax Online as the best tax software for tax pros wanting online software.
