Offshore Partnership & LLC (1065) Tax Return Preparation for CPA Firms.

1065 returns are time-intensive in proportion to their partner count. multi-member LLCs, limited partnerships, and operating partnerships all require K-1 schedules for every partner, capital account maintenance, outside basis tracking, and — in more complex situations — guaranteed payment analysis, Section 754 election adjustments, and tiered partnership reconciliation. our certified offshore accountants handle the full preparation. your CPAs review and sign. the administrative burden of 1065 preparation comes off your team entirely.

Our preparation process

Five stages. allocation verification built in.

A documented, repeatable process for every 1065 — with a dedicated allocation verification step that most preparation workflows skip.

Step one
Prior year review and intake
Prior year 1065 reviewed before we begin. partner composition, capital account positions, and any elections in effect confirmed. source documents checked for completeness. a single query list sent for anything missing.
Step two
Allocation verification
Before preparing K-1s, we review the operating agreement or partnership agreement and verify that allocations match the governing document. incorrect allocations are among the most common and most consequential 1065 errors — we address them before they appear in the return.
Step three
Preparation
Full 1065 and all K-1 schedules prepared in your software. capital accounts updated. state returns prepared for all applicable jurisdictions.
Step four
Internal QA
Senior accountant review of all schedules. K-1 totals reconciled to the return. any judgment items flagged in preparer notes for your attention.
Step five
Delivery
Reviewer-ready file in your software.

Quality control

Allocation accuracy is the non-negotiable checkpoint.

Allocation accuracy against the governing agreement is the non-negotiable quality checkpoint on every 1065. capital account reconciliation to prior year closing balances is verified before any K-1 is finalized. the senior accountant review confirms K-1 totals, return totals, and state return consistency before delivery.
