Hiring a CPA for a 1065 tax return is not the same as hiring a CPA for a personal return. The skill sets overlap, but the specific knowledge required to prepare a Form 1065 correctly, which is understanding partnership agreements, maintaining tax-basis capital accounts, allocating income according to the terms of the agreement, and making sure every K-1 is accurate before it goes to a partner, is not something every general tax preparer has. Most CPAs can file your taxes, but only a few can prepare a partnership tax return the way it needs to be prepared.
The questions below are the ones worth asking before you hand over your documents. The answers will tell you quickly whether you are talking to someone who treats the 1065 as a specialty or as a checkbox.
Volume is not the only measure of expertise, but it is a reasonable starting point. A CPA who prepares a handful of Form 1065 returns each year alongside hundreds of individual returns is approaching it very differently from one whose practice is built around 1065 tax preparation.
Ask the question directly, and follow it up by asking what percentage of their practice is business returns versus individual returns. The answer tells you where your return sits in their priority stack.
Tip: A CPA who specializes in partnership tax return preparation will be able to speak fluently about capital account maintenance, allocation methods, and the BBA audit regime without you having to prompt them. If those topics require explanation, that is useful information.
This question separates preparation from data entry. The partnership agreement is the governing document that controls how every item of income, deduction, and credit is allocated among partners. It determines what goes on every Schedule K-1. A professional 1065 tax preparer who does not review the agreement before preparing the return is allocating income based on assumptions, and those assumptions may not reflect what the agreement actually says.
The right answer to this question is yes, without hesitation, and the CPA should be able to explain specifically what they are looking for when they read it, such as allocation percentages, special allocations, guaranteed payment structures, mid-year ownership changes, and any provisions that affect how distributions are handled.
Tip: If your partnership agreement has been amended since it was originally drafted, bring every amendment, not just the original. Allocations can change significantly with amendments, and a CPA who only reviews the original agreement may prepare the return incorrectly even if they did read it.
Since 2020, the IRS has required partnerships to report partners' capital accounts on a tax basis in Box L of every Schedule K-1. This is not the same as the book basis balance that most accounting software produces. A CPA who pulls capital account numbers from QuickBooks or a similar platform without converting them to tax basis is filing with incorrect information.
The answer you are looking for is that capital accounts are maintained on a tax basis throughout the year, verified against contributions and distributions by partner, and reconciled to each partner's allocated share of taxable income or loss before the return is finalized. If the CPA is unfamiliar with the distinction between tax-basis and book-basis capital accounts, that is a significant gap for 1065 tax preparation.
Tip: According to IRS requirements, tax-basis capital accounts must reflect each partner's contributions, distributions, and cumulative share of taxable income or loss, and not the accounting software balance. Ask specifically how the preparer handles the conversion if books are maintained on a GAAP basis.
A partner's ability to deduct losses from the partnership is limited by three separate rules that must be applied in sequence. The first is the basis limitation, i.e. a partner cannot deduct losses that exceed their tax basis in the partnership.
The second is the at-risk limitation, which limits deductions to amounts the partner could actually lose.
The third is the passive activity limitation, which restricts losses from activities in which the partner does not materially participate.
These three layers interact with each other, and none of them are calculated automatically by entering numbers into a form. They require tracking each partner's outside basis over multiple years, understanding their participation level in the partnership, and applying the rules correctly before any loss is passed through to the personal return.
A CPA for 1065 tax return preparation who cannot explain how they handle basis tracking is likely not doing it.
Tip: If you received a loss on a prior year K-1 that was not fully deductible on your personal return, ask whether the suspended loss is being tracked and carried forward. Suspended losses do not disappear as they are deductible in a future year when the limitation no longer applies, but only if someone is keeping track of them.
The Form 1065 and each partner's Form 1040 are not independent documents. The K-1 that flows from the 1065 feeds directly into the personal return, and the decisions made on the entity return affect each partner's income tax, self-employment tax, estimated payment obligations, and deduction picture for the entire year.
A CPA who prepares the 1065 without any involvement in the partners' personal returns is working with incomplete information in both directions. They do not know how a given allocation decision will affect each partner's personal tax picture, and the partner's personal preparer does not have the context to catch errors or inconsistencies in the K-1 before the personal return is filed.
The best outcomes come from a CPA who either handles both or communicates actively with whoever does the personal returns to make sure nothing falls through the gap between the two.
Tip: If different CPAs handle the entity return and the personal returns for the same partners, ask specifically how they communicate. Regular coordination between preparers is what prevents a K-1 error from going undetected until someone gets an IRS notice.
An extension on the Form 1065 affects every partner in the partnership. Filing Form 7004 by March 16, 2026 moves the deadline to September 15, 2026, but it does not automatically extend each partner's personal return. Partners who do not extend their own returns before April 15 while waiting for a September K-1 face their own late-filing consequences.
A CPA who handles extensions well communicates the decision proactively, explains the downstream effect on each partner's personal filing timeline, and ensures that partners who need to extend their personal returns are doing so before the April 15 deadline passes. An extension should never be a surprise delivered after the original deadline has already come and gone.
Tip: According to the IRS, the penalty for a late Form 1065 is $255 per partner for each month or partial month the return is late, up to 12 months. An extension eliminates that penalty entirely as long as Form 7004 is filed on time. Always confirm your CPA files the extension before March 16, not after.
Most partnerships are subject to the Bipartisan Budget Act centralized audit regime, which changed the way the IRS audits partnerships. Under the BBA rules, any audit adjustments are assessed at the partnership level by default, meaning the entity pays the cost of any underpayment found during an audit, not the individual partners.
For many partnerships, electing out of the centralized regime using Schedule B-2 is the better outcome, because it routes any audit adjustments directly to the individual partners instead. The election is available to partnerships with 100 or fewer eligible partners, and it must be made annually on the Form 1065. A CPA who is not familiar with the BBA election or has never discussed it with you is leaving a meaningful compliance and risk management decision unaddressed.
Tip: The Partnership Representative designated on your Form 1065 has sole legal authority to act on behalf of the partnership in an IRS audit. This designation must be confirmed or updated every year on the return. Ask your CPA specifically whether the Partnership Representative is correctly designated on your current return.
Partnership tax return preparation is more complex than most clients expect, and pricing varies significantly depending on the number of partners, the number of schedules required, whether capital accounts need to be reconstructed, and whether any special allocations, elections, or state filings are involved. A CPA who quotes a flat fee for every 1065 without asking about any of those factors is either ‘underscoping’ the work or standardizing at a level that does not reflect the actual complexity of your return.
Ask specifically what is included in the quoted fee, whether K-1 preparation for all partners is included, whether capital account analysis is included, whether state filings are included, and how mid-year changes or unusual transactions are priced. The goal is a clear, written engagement letter before work begins, not a fee that changes when the return turns out to be more complex than the preparer anticipated.
Tip: The cost of 1065 tax preparation services is a deductible business expense for the partnership. The cost of fixing errors, such as amended returns, penalty abatement requests, IRS correspondence, and amended K-1s, is not. A higher fee for thorough preparation is almost always less expensive than the downstream cost of inadequate preparation.
Finding a professional 1065 tax preparer who can answer these questions confidently and specifically is finding someone who actually does the work the way it should be done. Most partners do not know these questions exist because nobody has ever asked them. Asking them once, before the engagement starts, tells you more about the quality of the return you are going to receive than any amount of research after the fact.
At TrueView CPA, 1065 tax preparation for partnerships and multi-member LLCs across Dallas and Texas is built around being able to answer every one of these questions with specifics, not generalities.
