Lacerte K-1 support for 1040 preparation

Last updated: September 14, 2026

This article summarizes the current K-1 support for 1040 tax preparation data entry within Lacerte tax software.

Overview

FiledAI currently supports K-1 schedules for the following entity types in Lacerte:

  • 1065 Partnership K-1

  • 1120S S-Corporation K-1

  • 1041 Estate or Trust K-1

FiledAI reads all three K-1 types. Within Lacerte, FiledAI automatically enters supported information into the applicable data entry screens. Screens and fields that are not currently supported are left untouched if they already contain information from proforma or rolled-forward data.

For 1065 K-1 schedules, FiledAI currently supports:

  • Lines 1–21

  • General Info

  • QBI Activity — partial support; additional review may be needed

FiledAI does not currently enter information into the following Lacerte screens for 1065 K-1s. If information already exists in these screens from proforma or rolled-forward data, FiledAI leaves it untouched:

  • At-risk recapture

  • At-Risk Carryovers

  • Basis Carryovers

  • AMT Basis Carryovers

  • State Adjustments and Credits

  • Form 6198

  • Oil & Gas

  • Prior Year Unallowed Qualified Basis Income Deductions

1120S S-Corporation K-1 support

For 1120S K-1 schedules, FiledAI currently supports:

  • Lines 1–17

  • QBI Activity — partial support; additional review may be needed

FiledAI does not currently enter information into the following Lacerte screens for 1120S K-1s. If information already exists in these screens from proforma or rolled-forward data, FiledAI leaves it untouched:

    • Information about the Beneficiary

  • QBI Activity — partial support; additional review may be needed

Important expectations

  • Coded boxes and partner-level detail may still require user input.

  • Separate state amounts may need to be coded by the user.

  • QBI Activity is partially supported and may require additional review.

  • Unsupported Lacerte screens are not overwritten by FiledAI; existing proforma or rolled-forward data is left untouched.

Future coverage target

The target is to support all writable fields in Lacerte for all three K-1 types. Current support is limited to the fields and screens listed above.
