Your information stays with you

Leave Social Security numbers, PINs, passwords and bank details out of your notes. When documents are needed, we will show you how to share them securely.

Start here

  • Previous partnership returns and K-1s
  • The current partnership or operating agreement
  • Year-end records and changes in partners

Start with your partnership and partners

  • Include the detailed transaction report (general ledger) and any unresolved items your bookkeeper has noted.
  • Gather bank, credit-card and payment-platform statements, plus any reports checking them against your books.
  • Bring sales and expense details. Point out refunds, transfers or duplicate entries you already know about.

Partner contributions, withdrawals and loans

  • List guaranteed payments, reimbursements and expenses paid on behalf of partners.
  • Gather loan agreements, guarantees and any schedules showing how debt is allocated among partners.

Equipment, loans and business changes – if applicable
  • Bring your previous depreciation schedules and a list of business assets you still own.
  • Gather purchase invoices for equipment, vehicles, software and improvements, with the dates you started using them.
  • Include records for assets sold, traded in, disposed of, damaged or lost during the year.
  • Gather loan agreements, year-end balances and statements separating principal repayments from interest.
  • Bring mileage logs and other business-use records. Let us know about any personal use.
  • Tell us about a business purchase, sale, restructure or large one-time transaction, and bring the agreements.
Information for your partners
  • List who needs a Schedule K-1 and who prepares each partner’s return.
  • Bring previous state withholding, composite-return and pass-through entity tax records, if applicable.
  • Tell us about changes that may involve international reporting or a partner’s specialist advisor.
  • Note what partners need for their own returns and any dates already agreed for sharing it.
Tax payments and where you do business
  • Gather federal and state payment confirmations, extensions, refunds and records of unused tax credits.
  • List the places where the business, employees and owners worked, including any moves during the year.
  • If you operate in several states, bring sales by state, registrations and a list of previous state filings.
  • Bring payroll, sales-tax, local-tax and information-return records. We will confirm which services are included.
  • Tell us about foreign owners, accounts, investments or transactions so we can discuss any additional review.
Before we get started
  • Make a short list of anything missing or being corrected, and when you expect it.
  • Tell us early about tax letters, deadlines or questions from a previous year.
  • We will confirm which returns and states we are handling, including any owner returns or bookkeeping cleanup.
  • Ask us how to share documents securely and confirm who can approve the work.
  • We will explain the next steps for questions, reviewing your return, signatures and filing confirmation.

This is a general preparation guide. We may ask for additional records for your circumstances; the checklist does not determine tax eligibility or replace individual advice.

A complete picture can start with incomplete records.

Bring the business and partner information you have. We’ll help identify what is still needed.
