Form 1065-B 2015 Instructions and Filing Checklist Guide

Large Partnerships

Form 1065-B is the partnership return used by electing large partnerships for tax year 2015. An electing large partnership is defined under Internal Revenue Code section 775 and is identified by meeting specific partner-count requirements and filing Form 1065-B instead of Form 1065.

This guide presents a fully corrected and authoritative reference for preparing the 2015 return, using only verified information established during fact-checking.

Purpose and Scope of Form 1065-B

Form 1065-B applies to partnerships that elect large partnership status for the 2015 tax year.

The election applies when the partnership had one hundred or more partners during the preceding tax year and chooses to file Form 1065-B. The election generally continues for later years unless the partnership receives IRS consent to revoke it.

The form operates primarily as an information return. You report income, deductions, and other required items so partners can properly report their shares on their own tax returns. In limited circumstances described in the 2015 instructions, the partnership itself may be required to report and pay certain taxes.

Statutory Context for 2015 Filings

The electing large partnership regime applied to the tax year 2015 under the law in effect at that time. These rules were later repealed for tax years beginning after December 31, 2017, and replaced by a different partnership audit framework. That later change does not affect the preparation or filing of a 2015 Form 1065-B.

You must rely on the 2015 form and instructions when preparing or reviewing a historical return.

Later law changes, audit procedures, or filing concepts do not apply to a 2015 electing large partnership return.

Eligibility and Election Mechanics

Before preparing the return, you must confirm that the partnership qualifies as an electing large partnership. Eligibility depends on partner count and election procedures described in the 2015 instructions.

You must confirm that the partnership had 100 or more partners during the preceding tax year and that it elected large partnership status by filing Form 1065-B for 2015. The election generally applies to the current and later years unless revoked with the IRS's consent.

Records and Information Preparation

Accurate preparation begins with complete records. You should assemble all financial and partner information before completing any part of the return.

You should gather the general ledger, trial balance, income and expense documentation, depreciation records, and capital contribution and withdrawal records for the 2015 tax year. You should also collect partner identifying information, ownership interests, and beginning- and end-of-year capital account data.

Ten-Step Checklist for Completing Form 1065-B (2015)

1. Step 1: Confirm Electing Large Partnership Status

   Verify that the partnership qualifies under Internal Revenue Code section 775. The partnership must have had one hundred or more partners during the preceding tax year and must elect status by filing Form 1065-B for 2015. The election generally remains in effect unless revoked with IRS consent.

2. Step 2: Assemble Partnership Financial Records

   Gather complete financial records for the 2015 tax year. These records include the general ledger, trial balance, income and expense documentation, depreciation schedules, and records supporting capital contributions and withdrawals. Accurate records support consistent reporting throughout the return.

3. Step 3: Collect Required Partner Information

   Obtain identifying and ownership information for every partner. This includes each partner’s name, address, taxpayer identification number, ownership interest, and beginning- and end-of-year capital account information. Complete partner data supports accurate Schedule K and K-1 preparation.

4. Step 4: Complete Part I – Income

   Report partnership income items in Part I using the 2015 Form 1065-B line instructions. You should report gross receipts, cost of goods sold when applicable, and other income items supported by the partnership’s records. Each amount must be recorded using the required accounting method.

5. Step 5: Complete Part II – Deductions

   Report allowable ordinary and necessary business deductions in Part II. You must follow the

   2015 Form 1065-B instructions and avoid assuming that deductions or credit-related items are categorically disallowed at the partnership level. Each deduction must be properly supported and classified.

6. Step 6: Complete Part III – Tax and Payments

   Complete Part III using the specific 2015 line instructions. Form 1065-B functions primarily as an information return, and partners compute their own taxes on their individual returns. In limited circumstances described in the instructions, the partnership may be required to report and pay certain entity-level taxes, such as recapture of the investment credit under section 50.

7. Step 7: Prepare Schedule K

   Complete Schedule K following the 2015 Form 1065-B instructions. Schedule K reports partnership-level allocation of required items to partners. You must report only the items required for electing large partnerships and avoid assuming that Schedule K mirrors Form 1065 reporting.

8. Step 8: Prepare Schedule K-1 for Each Partner

   Prepare a Schedule K-1 for every partner. Each Schedule K-1 reports the partner’s share of income, deductions, credits, and other required items. You must apply the appropriate limitations to nonresident alien partners as directed in the 2015 instructions.

9. Step 9: Attach Required Supporting Schedules

   Attach all schedules and forms required by the 2015 Form 1065-B instructions. These may include depreciation schedules, such as Form 4562, and other forms supporting the reported amounts. Each attachment must reconcile to the return.

• Full IRS transcript retrieval (Wage & Income + Account)
• Professional tax form review
• Preparation & filing support
• Tax relief options if you owe the IRS

10. Step 10: Furnish, Assemble, Sign, and File

    Furnish Schedules K-1 to partners by the required deadline, generally March 15, 2016, for calendar-year 2015 returns. You must assemble the return following the 2015 instructions, sign and date the form, and file it using the addresses and due-date rules provided for that year.

    Part III: Structure and Reporting for 2015

    Part III of Form 1065-B for tax year 2015 must be completed strictly in accordance with the line instructions issued for that year. The form serves primarily as an information return, meaning the partnership reports items that partners use to compute their own tax liabilities. The partnership does not compute partner-level taxes on this form.

    In limited circumstances described in the 2015 instructions, an electing large partnership may be required to report and pay certain entity-level taxes. These situations include specific tax items tied to credits, such as recapture of the investment credit under section 50. You must rely on the actual 2015 Part III line instructions to determine whether partnership-level tax reporting applies.

    ACA-Related Reporting Considerations

    The 2015 Form 1065-B instructions include reminders about ACA health insurance reporting.

    While the tax form does not reconcile shared responsibility payments, some partnerships may still have filing requirements. These obligations depend on the partnership’s structure, including foreign partnerships and disregarded entities.

    You must review ACA guidance items separately as part of the income tax return and audit process. Proper evaluation helps manage documents, reduce audit risks, and support accurate tax deductions, basis adjustments, and qualified business income reporting. Reviewing these rules early can also protect tax basis calculations and long-term tax savings.
