Introduction: Understanding PA 1065
"PA 1065" is a common search phrase, but there is no Pennsylvania form with that exact name. People usually mean Pennsylvania's PA-20S/PA-65, the S Corporation/Partnership Information Return. Federal Form 1065 is a separate partnership return filed with the IRS.
This guide is for partnership owners, LLCs taxed as partnerships, tax professionals, and businesses with Pennsylvania filing duties or nonresident partners. That includes Australian owners of US partnerships, who often encounter this form for the first time through a Pennsylvania resident partner.
We cover who files, what the return reports, how it connects to other forms, the filing steps, deadlines, penalties, and when to bring in help. Figures below come from the 2025 tax year instructions, so check the current year's versions before you file.
Key Takeaways
- The partnership files the Pennsylvania return; each partner uses the schedules it issues on their own return.
- A Pennsylvania-resident partner at year-end can trigger filing even with no Pennsylvania activity.
- PA-20S/PA-65, federal Form 1065, Forms 1099 and Form 1040 serve different purposes.
- The 2025 calendar-year return is due April 15, 2026; the federal return is due March 16, 2026.
What Is PA 1065 and Who Needs to File It?
Clarifying the "PA 1065" terminology
The official title of the 2025 form is PA-20S/PA-65, PA S Corporation/Partnership Information Return. Using the right name matters because the state and federal returns have different schedules, filing methods, and supporting documents. Federal Form 1065 covers federal partnership items, while the Pennsylvania return covers Pennsylvania classes of income and sourcing.
Who may have a Pennsylvania filing obligation
Per the 2025 PA instructions, domestic or foreign partnerships and LLCs classified federally as partnerships file when either of these applies:
- Any gross taxable income or loss is allocable or apportionable to Pennsylvania, regardless of amount or distribution.
- At year-end, at least one partner is a Pennsylvania resident individual, estate, trust, or a disregarded entity owned by a resident individual.
Nonresident-only ownership does not remove the first trigger. Having no Pennsylvania activity is not an exemption by itself, because the resident-partner test still applies. Inactive partnerships still file using the Inactive oval, and include the owner directory and RK-1/NRK-1 schedules.
Partnerships whose partners are all C corporations are the exception: they do not file this return.
Partnership versus partner responsibility
The partnership files the entity-level return. Each partner separately reports their allocated income, losses and credits on their own state and federal returns. Filing the partnership return never replaces a partner's own filing.
What Information Does the Return Report?
Partnership income and Pennsylvania adjustments
The return starts from federal figures and converts them to Pennsylvania amounts. Schedule M classifies federal Schedule K income (business, interest, dividends, gains, rental and royalty) and reconciles business and rental results to Pennsylvania rules. Pennsylvania does not allow federal bonus depreciation, so expect an adjustment there.
Rental income is allocated inside or outside Pennsylvania. Apportioned business income flows to Schedule H. For multistate partnerships, wholly Pennsylvania operations allocate income to the state, while wholly out-of-state operations cannot allocate income to the state.
Partner ownership and schedules
The return needs each owner's:
- Name and address
- SSN or FEIN
- Partner or entity type
- Profit-sharing, loss-sharing and capital-ownership percentages
RK-1 reports resident owners' classified items. NRK-1 reports nonresident owners' items, including Pennsylvania-source income. Entity owners may receive both. The "Ownership of capital" line on the RK-1 is a percentage, not a dollar capital-account balance.
Capital accounts
Where federal K-1 Item L is required, the IRS Form 1065 instructions call for the transactional tax-basis method. Negative ending capital is permitted when losses and distributions exceed contributions and income. Tax-basis capital also differs from:
- Outside basis, which can include liabilities and partner-specific adjustments
- Book capital
Reconcile all of these to the partnership's records.
Withholding, payments and composite returns
Pennsylvania's pass-through guide says to withhold for nonresident individuals, estates and trusts on expected distributable Pennsylvania-source income. You do not withhold for another entity or a Pennsylvania resident individual, and intangible income such as interest and dividends is excluded.
- The estimated withholding calculation uses 3.07%.
- The partnership is jointly liable with covered nonresidents.
- Owners' own estimated payments do not reduce the partnership's withholding duty.
- Final withholding is due April 15 for calendar-year entities; quarterly remittances are encouraged.
- A partnership may file PA-40 NRC as a composite return for electing nonresident individuals. It is separate from PA-20S/PA-65 and needs its own extension.
Gather these records before you start:
- Federal return, trial balance and general ledger
- Partnership agreement
- Contribution and distribution records
- Prior-year return
- Partner addresses and state allocation workpapers
How PA 1065 Connects to Other Tax Forms
Federal Form 1065 versus the Pennsylvania return
Form 1065 is the federal information return, and each K-1 reports a partner's share of income, deductions and credits. Partners are taxed on their shares whether or not they are distributed. The Pennsylvania return is a separate filing. Federal figures feed it through Schedule M, and you should document that reconciliation.
Pennsylvania requires these items with the state return:
- Complete federal return, schedules, statements and federal K-1s
- Other attachments submitted as PDFs
- RK-1/NRK-1 schedules in the e-file package itself, not as PDFs
Missing required documents makes the return incomplete.
Partner schedules versus individual returns
Individual partners use the classified amounts from their RK-1 or NRK-1 on Form PA-40. Other partners use their applicable Pennsylvania returns. A US partner also reports federal items on Form 1040. The partnership return does not do this for them.
Form 1099
A Form 1099 reports particular payments to a recipient, such as 1099-NEC for nonemployee compensation. A partnership return reports the entity's tax information and partner allocations. Schedule B, lines 16a and 16b of Form 1065 ask whether any payments required Forms 1099 and whether those forms were filed, so a partnership can carry both duties.
| PA-20S/PA-65 | Form 1065/K-1 | Form 1099 | Form 1040 | |
|---|---|---|---|---|
| Purpose | State entity information | Federal entity information and partner allocation | Payment reporting | Individual tax reporting |
| Filed by | Partnership | Partnership | Payer | Individual |
Filing Process, Deadlines, and Compliance Checklist
Confirm the obligation
Start with the legal structure, federal tax classification, tax year, Pennsylvania activity, income sources and each partner's residency. Then test the two filing triggers above against the current year's instructions.
Prepare the data
- Reconcile the books to the federal return.
- Identify Pennsylvania adjustments, sourcing and allocation percentages.
- Record capital activity and partner changes.
- Check partner IDs and carryforwards so schedules match.
Complete schedules and submit
Prepare RK-1 and NRK-1 schedules for each owner and send them out. Address withholding, composite filing and estimates at the same time.
Key 2025 dates:
- Calendar-year return and schedules: April 15, 2026
- Extended date: September 15, 2026
- Fiscal-year return: 15th day of the fourth month after year-end, with a five-month extension
Third-party preparers filing 11 or more PA-20S/PA-65 returns must e-file.
Extensions
With a federal extension and no additional catch-up withholding, Pennsylvania grants five months without a separate REV-276 form. Include federal Form 7004 with the state return. Otherwise file REV-276 by the original deadline. Either way, the extension does not extend payment.
After filing
- Check the state acknowledgment, not just transmission. Rejected filings have a 10-day correction period.
- Amended returns can be e-filed. Explain the changes and send amended RK-1/NRK-1 schedules to affected owners.
- Follow the instructions and deadline on any Department of Revenue notice. A dispute needs an appeal, not an amended return.
- Keep the return, workpapers, federal return, schedules, payment confirmations and ownership records. IRS guidance generally says three years, longer in some cases.
Common Mistakes and When to Seek Help
Frequent errors
- Mixing up PA-20S/PA-65, Form 1065, Form 1099 and Form 1040
- Missing Pennsylvania-source income
- Treating resident and nonresident partners the wrong way
- Wrong ownership percentages or inconsistent partner IDs
- Omitted schedules
- Federal-to-state reconciliation gaps
- Assuming an extension covers withholding payments
Official 2025 penalties include:
| Failure | Penalty |
|---|---|
| Failure to file | $250 may be imposed |
| Missing RK-1 or NRK-1 | $250 per missing schedule |
| Late nonresident withholding | 5% per month, maximum 50% |
| Non-electronic payment of $15,000+ | 3% of payment, maximum $500 |
Interest on 2025-2026 underpayments is 7% annually, calculated daily.
When additional review makes sense
Get a second look when any of these apply:
- Foreign ownership
- Multi-state operations
- Tiered partnerships
- Entity classification changes
- Nonresident partners
- Uncertain nexus
- Large book-to-tax differences
For tiered structures, Pennsylvania keeps income categories separate rather than combining them. Foreign partners can also face separate federal IRC section 1446 withholding, which does not replace the Pennsylvania review.

Frequently Asked Questions
What is PA 1065 used for?
The term usually refers to Pennsylvania's PA-20S/PA-65 information return. It reports partnership income, deductions, credits and partner allocations. It does not replace each partner's individual return.
Is PA 1065 the same as a 1099?
No. A 1099 reports specific payments to a recipient, while the partnership return reports entity information and allocations. A partnership may still have separate 1099 duties.
Is PA 1065 the same as a 1040?
No. The partnership files its own return. Form 1040 is an individual's federal income tax return, which a partner completes using information from the partnership.
Do I file if I have no Pennsylvania activity?
Possibly. A Pennsylvania-resident partner at year-end can trigger filing on its own.
Does an extension delay withholding payments?
No. The extension covers filing only, so pay any withholding by the original date.
