IRS Form 1065 (2020): Download, Complete, and File Your Return

IRS Form 1065 is the U.S. Return of Partnership Income, required for domestic partnerships to report income, deductions, gains, losses, and credits for the 2020 taxable year. It allocates partnership items to each partner via Schedule K-1 and applies to certain foreign partnerships with U.S.-source income.

Late Filers

Partnerships that missed the March 15, 2021, deadline may still file Form 1065, but per-partner monthly penalties continue accruing until the return is submitted.

Composite / Special Filers

Multi-member LLCs and limited liability partnerships filing as domestic partnerships must use Form 1065 and attach Schedule K-1 for each partner's share of items.

Income / Investment Type

Partnerships reporting business income, capital gains, dividends, interest, and rental income must disclose all categories on Form 1065 and Schedule K for 2020.

Gains / Reporting Requirement

Partnerships must report capital gains and losses from sales of property on Schedule D and carry those totals to Schedule K for proper partner allocation.

IRS Compliance

Filing Form 1065 satisfies federal information return obligations and helps avoid IRS notices such as CP162A or CP162B for late or incomplete 2020 partnership filings.

Amended Returns

BBA partnerships must file an Administrative Adjustment Request, not an amended return, to correct errors on a 2020 Form 1065; electronic filers use Form 8082.

Follow the steps below to complete your 2020 Form 1065 accurately. Some steps reflect rules specific to the 2020 tax year; do not replace them with current IRS instructions.

Step 1 — Gather Documents

Collect all 2020 financial records, including income statements, expense receipts, bank statements, prior-year returns, and IRS transcripts. To request transcripts, use Form 4506-T or access a business tax account at IRS.gov.

[2020 ONLY] Step 2 — Confirm Filing Status / Election

Confirm the entity classification before filing. Eligible types include general partnerships, limited partnerships, limited liability partnerships, and multi-member LLCs; certain foreign partnerships with U.S.-source income may also qualify. Do not use S corporation or C corporation status on Form 1065, as these require different returns. The partnership must have a valid Employer Identification Number (EIN) before filing.

Step 3 — Report All Income

Report all income on Form 1065 lines 1–7 and Schedule K for separately stated items, including ordinary business income, rental income, interest, dividends, and capital gains. For 2020, COVID-19 credits, including the Employee Retention Credit and FFCRA payroll credits, are separately stated on Schedule K-1 and are not treated as taxable income unless the IRS specifies otherwise.

Step 4 — Calculate Tax Liability

Form 1065 does not calculate partnership-level income tax; a partnership generally does not pay tax on its income. Profits and losses pass through to partners, who report partnership items on individual returns. Schedule K-1 carries guaranteed payments, Section 179 deductions, and self-employment items affecting each partner's AGI.

[2020 ONLY] Step 5 — Apply 2020 Rate Schedule

Partnerships are not subject to entity-level income tax; tax rates apply at the partner level, not the partnership level. Unlike C corporations, partnerships do not pay tax on partnership income. Standard deductions and personal exemptions are not available on Form 1065. For 2020, Section 163(j) limits business interest expense deductions to 50% of adjusted taxable income.

[2020 ONLY] Step 6 — Attach Schedules and File

Attach Schedule K-1 for each partner, Schedule D for capital gains, and Schedule B-1 if applicable. E-filing is mandatory for partnerships with over 100 partners. Mail the paper returns to your applicable IRS service center using certified mail with a return receipt.

Missing Partnership Records for 2020?

Partnerships filing late may no longer have easy access to the original 2020 financial records. IRS business transcripts for partnership accounts can help reconstruct key financial data without relying on estimates that may invite follow-up IRS notices or balance adjustments.

IRS Business Tax Account Transcript

Shows payments, assessed penalties, IRS adjustments, and credits on the partnership's account for 2020. Request online at IRS.gov via a business tax account or by submitting Form 4506-T by mail. 

IRS Return Transcript

Shows most line items from the originally filed 2020 Form 1065, helping partnerships verify previously reported income, deductions, credits, and other tax information submitted to the IRS. 

Prior Employer or Business Records

Employers and business entities must retain payroll and earnings records for several years; request 2020 W-2 and compensation documentation directly from them for accurate reconstruction. 

Prior Tax Preparer or CPA

Request copies of the 2020 partnership return, supporting workpapers, and Schedule K-1s from the preparer of record to ensure accurate financial documentation and record reconstruction.

Do not estimate figures on a reconstructed return. Use IRS transcripts to match reported amounts and reduce follow-up notices or account balance adjustments from the IRS.

These are the most frequent errors causing IRS delays, rejected returns, or missed credits on the 2020 Form 1065.

• Wrong tax year form: Submitting a Form 1065 edition other than 2020 will cause processing errors, IRS rejection, or a mismatch that delays the return and triggers additional IRS notices.

• Incorrect BBA amendment procedure: Filing an amended Form 1065 instead of an Administrative Adjustment Request under BBA rules produces an improper filing that the IRS will not process.

• Minimum late-filing penalty miscalculation: The 2020 per-partner penalty is $210 per month; misreading this as a flat return-level charge significantly understates total partnership exposure under IRS assessment rules.

• Refund deadline miscalculation: Form 1065 is an information return; refunds are claimed at the partner level on individual returns, not by the partnership, making entity-level refund claims invalid.

• Misapplying the Section 163(j) interest limitation: Using outdated interest expense rules instead of the 2020 CARES Act modification, which raised the deduction limit to 50% of adjusted taxable income, produces an incorrect return.

• Missing Schedule K-1 for each partner: Omitting or incorrectly completing Schedule K-1 for any partner causes an incomplete return, triggers IRS CP162 notices, and prevents partners from filing accurate individual returns.

• E-filing threshold assumption: Assuming e-filing is always required regardless of partnership size is incorrect; the 2020 mandatory e-filing threshold applies only to partnerships with more than 100 partners.

• Wrong EIN or missing partner SSN: Entering an incorrect Employer Identification Number or omitting partner Social Security numbers on Schedule K-1 triggers IRS matching failures and delays processing of the return.

• Unsigned return: A Form 1065 not signed by an authorized partner is invalid; the IRS will not process it, and penalties continue accruing during the correction delay.

What is IRS Form 1065 (2020) used for?

IRS Form 1065 (2020) is the U.S. Return of Partnership Income, used by domestic partnerships to report income, deductions, gains, losses, and credits for the 2020 taxable year. It is an information return; the partnership itself generally does not pay income tax on its income. 

Can I still file a 2020 Form 1065 return?

Yes, a 2020 Form 1065 can still be filed after the deadline. Filing stops the accumulation of per-partner monthly late-filing penalties, which apply for up to 12 months. BBA partnerships that need to correct a previously filed return must file an Administrative Adjustment Request rather than an amended return.

What penalties apply to a late 2020 filing?

For 2020, the late-filing penalty for Form 1065 is generally $210 per partner per month for each month the return is late, up to 12 months. Because it applies per partner, total penalties increase quickly for partnerships with multiple partners. Filing now stops additional accrual. 

How do I get 2020 transcripts for this account?

To request transcripts for a partnership tax account, access a business tax account at IRS.gov or submit Form 4506-T by mail to request a transcript copy. You may also call the IRS Business and Specialty Tax Line at 800-829-4933 for assistance.

What does a return transcript show for a 2020 filing?

A 2020 IRS return transcript for Form 1065 shows most line items from the originally filed return, including income, deductions, and credits. An account transcript shows payments, assessed penalties, IRS adjustments, and the account balance. Neither transcript is a substitute for the complete return; request both when reconstructing records.

What is the deadline for claiming a refund on a 2020 return?

Form 1065 is an information return, and partnerships generally do not pay income taxes or receive refunds at the entity level. Refund claims for 2020 are made at the partner level on individual or corporate income tax returns. The standard refund deadline for a timely filed 2020 individual return was generally April 15, 2024.

Should I also file a state return or an amended state return for 2020?

Most states require partnerships to file a state information return that corresponds to the federal Form 1065. Requirements vary by state, including filing deadlines, partner withholding obligations, and composite return rules for nonresident partners. If the federal 2020 Form 1065 is late or corrected, a corresponding state filing may be required. 

Is e-filing available for the 2020 Form 1065?

Yes, e-filing was available for the 2020 Form 1065. Partnerships with more than 100 partners were required to file electronically. Partnerships with 100 or fewer partners could e-file voluntarily or submit a paper return to the applicable IRS service center by mail.
