Tax prep support
Partnership tax preparation support
Finbryn prepares Form 1065 and partner K-1s from your books, rolling forward capital accounts and tracking special allocations, and hands the finished draft to a credentialed signer well ahead of the March 15, 2027 deadline for calendar-year 2026 partnerships, so nothing gets rushed in the final week before filing.

Capital accounts that actually roll forward
A partnership return lives or dies on capital account accuracy. We roll each partner's account forward year over year from contributions, distributions, income and loss allocations, rather than plugging a number at year-end, so the K-1s tie to a history that holds up if a partner is ever questioned about it.
Multi-member LLCs included
Everything here applies equally to multi-member LLCs taxed as partnerships, which is most of them. Special allocations, fixed payments to partners for services or capital, and varying ownership percentages through the year are all common in these structures, and we build workpapers that handle them rather than defaulting to a simple pro-rata split.
Deadline
Calendar-year partnerships file Form 1065 by March 15, 2027 for tax year 2026, the same early date as an S corporation. Partners then need their K-1s with enough runway to prepare their own personal returns by April.
Mid-year ownership changes
Partners who join, leave, or change their percentage mid-year change how income allocates for that year. We track these changes as they happen in your books rather than reconstructing the timeline at filing time.
Where this fits
Real estate and professional-services partnerships in particular benefit from pairing this with estimated tax support for partners who receive K-1 income with no withholding attached. Monthly bookkeeping under bookkeeping keeps the capital accounts current through the year. See pricing for partnership preparation rates.
Questions
Frequently asked questions: Partnership tax preparation support
When is Form 1065 due?
Calendar-year partnerships file by March 15, 2027 for tax year 2026, the same early deadline as an S corporation.
Do you handle multi-member LLCs?
Yes, most multi-member LLCs are taxed as partnerships and file Form 1065, and we build the same capital-account and allocation workpapers for them.
What happens if a partner leaves during the year?
We track ownership changes as they happen in your books so income allocation for the year reflects the actual timeline, not a year-end estimate.
Do partners get their K-1s before their own filing deadline?
We build toward the March deadline specifically so partners have their K-1s in hand before their personal return is due in April.
What does partnership tax preparation support actually include, month to month?
Partnership tax preparation support covers trial balance tie-out and book-to-tax adjustments, along with partner capital account rollforward. The work runs inside QuickBooks Online, Xero, Drake Tax or UltraTax CS, the file stays under your own subscription, and a senior principal reviews the output before it reaches you each period.
How do you handle partners who joined or left mid-year?
We track capital contributions, distributions and ownership changes through the year so the K-1s reflect the correct split.
Do you prepare the partnership agreement allocations?
We work from the allocation terms in your partnership agreement; we do not draft the agreement itself.
How do we get started with partnership tax preparation support?
Getting started with partnership tax preparation support begins with a short review of your current records and software access. Once that is done we confirm scope and timing in writing, and ongoing work begins on the schedule agreed with you.
What if our records for partnership tax preparation support are not up to date?
If your records are behind, we scope a catch-up first so partnership tax preparation support starts from a clean, reconciled base. That catch-up is priced and timed separately from the ongoing engagement, so you always know what each part costs.
