What to Bring to Your Accountant: The Complete Checklist

Walking into a tax appointment unprepared costs you time and money. This complete checklist covers every document category your accountant needs, from income records to asset schedules, so you can arrive ready and get the most from every meeting.

What to Bring to Your Accountant (The Short Answer)

Your accountant needs two things at once: the summary outputs from your bookkeeping software and the original source documents that prove those numbers are correct. These fall into five main categories: identity and prior-year information, income records, expense and deduction records, payroll records (if applicable), and asset or depreciation records. Disorganized records are a normal starting point for most small-business owners, not a character flaw. This checklist exists to turn that pile into a productive appointment.

Arriving prepared is one of the most direct ways to reduce your compliance burden and make the most of your time with your CPA. Work through the five categories below before your meeting, and you will spend less time gathering documents after the fact and more time making decisions that actually move your business forward.

A Worked Example: What One Ann Arbor LLC Owner Gathered

Consider a sole-member LLC owner in Ann Arbor who runs a small consulting practice. She had been using QuickBooks all year and felt confident walking into her first tax appointment with a printed Profit and Loss statement and a Balance Sheet. Reasonable assumption. Incomplete preparation.

Her accountant also needed her bank statements for all 12 months, because software reports are only as reliable as the data entered into them. She needed her prior-year federal and state returns to verify whether any net operating loss carried forward from the previous year. She needed her mileage log, because she had driven to client sites throughout the year and mentioned it casually as the meeting wrapped up. And she needed documentation of the quarterly estimated tax payments she had made to the IRS and to the Michigan Department of Treasury, because without those records, her completed return would have shown a balance due she had already paid.

She left the appointment with a follow-up list. The second meeting, once she gathered everything, went smoothly. The lesson: software reports are the starting point, not the finish line.

The Complete Document Checklist by Category

Print this list or save it to your phone before your appointment. The goal is to gather everything in one pass so your accountant can move forward without follow-up requests.

Identity and Prior-Year Information

• Social Security number or EIN for the business
• EIN confirmation letter (CP 575) if you are a new client
• Prior-year federal tax return (all pages and schedules)
• Prior-year state return, including Michigan Form MI-1040 or business equivalent
• Any IRS or Michigan Department of Treasury correspondence received during the year

Why it matters: Your accountant cannot verify carryover items such as depreciation schedules, net operating losses, or prior-year estimated payments without last year's return. Missing this document is one of the most common causes of appointment delays.

Income Records

• All Forms 1099-NEC or 1099-K received
• Bank statements for every business account, all 12 months
• PayPal, Stripe, Square, or other payment-processor statements
• Sales records or invoices if income was not captured by 1099s
• Profit and Loss statement from your accounting software

Why it matters: Every income source needs to be accounted for. Payment processors now issue 1099-Ks for many transactions, and your accountant needs to reconcile those against your books.

Expense and Deduction Records

• Business credit card statements, all 12 months
• Receipts for large or unusual purchases
• Home office records: square footage of dedicated workspace and total home square footage, plus rent or mortgage interest and utility bills
• Mileage log (IRS Publication 463 requires the date, destination, business purpose, and miles driven for each trip)
• Records of business-related subscriptions, software, and professional development
• Health insurance premiums paid if you are self-employed
• Documentation of quarterly estimated tax payments made to the IRS and Michigan

Why it matters: Keeping audit-ready records year-round protects every deduction on this list. According to the IRS, vehicle deductions without contemporaneous mileage logs are among the top five deductions disallowed during small-business audits.

Payroll Records (If Applicable)

• Forms W-2 and W-3 filed for the year
• Quarterly payroll tax returns (Form 941 and Michigan equivalents)
• State unemployment tax filings
• Records confirming all payroll tax deposits were made on time

Why it matters: The American Payroll Association notes that W-2s, W-3s, and 941s must reconcile exactly to the payroll expense line in your general ledger before your return can be filed accurately. A single discrepancy forces a manual review.

Asset and Depreciation Records

• Depreciation schedule from your prior-year return or prior accountant's files
• Purchase receipts for any equipment, vehicles, or furniture bought during the year
• Records of any assets sold or retired during the year, including the original purchase price and date

Why it matters: Depreciation carries forward year after year. If your prior schedule is missing, your accountant must reconstruct it from source documents, which adds time and cost.

If you review this list and realize your books are not fully in shape before your appointment, that is a solvable problem. Our business tax preparation service page explains how we can help you get organized before the first meeting.

If You Are Meeting a New Accountant for the First Time

Switching accountants, or sitting down with a CPA for the first time, requires more historical documentation than a returning client meeting. Your new accountant is starting without any context about your business, so the initial appointment functions partly as an onboarding session.

Bring at least two years of federal and state tax returns, not just one. Your new accountant needs to see the trajectory of your business, check for carryover items, and confirm that prior returns were filed correctly. If any issues exist, identifying them early gives you options.

Depreciation schedules deserve special emphasis here. If your previous accountant or software maintained a depreciation schedule and you do not bring it to the first meeting, your new accountant will have to reconstruct it from your original asset records. That reconstruction takes time, and any gaps in documentation can affect the accuracy of future deductions.

This is also a good moment to think about the bigger picture of your business finances. A new accountant relationship is an opportunity to align your recordkeeping with a solid year-end tax planning process from the start, rather than catching up later.

Finally, bring your business-formation documents: your Articles of Organization, operating agreement, and any state filings that establish how your business is structured. Your accountant needs these to confirm your entity type and filing obligations.

Industry-Specific Documents: A Note for Mortgage and Lending Professionals

Independent mortgage brokers, loan officers operating as single-member LLCs, and small independent mortgage bankers carry a document set that goes beyond the standard checklist above. This industry has licensing and compliance costs that are ordinary and necessary business expenses under IRS Publication 535 guidance, but they are often buried in a generic miscellaneous category where they are easy to overlook or undervalue.

Bring itemized records of the following costs separately from your general expense reports:

• NMLS renewal fees and initial licensing fees
• Surety bond premiums
• Errors-and-omissions (E&O) insurance premiums
• State mortgage licensing fees
• Continuing education costs required to maintain your license

Your accountant will need to determine whether each of these costs qualifies as deductible given your specific business structure and situation. Presenting them as a single lump sum makes that analysis harder and increases the chance that individual items are missed.

If you pay independent loan processors or referral partners as contractors, bring 1099s for contractors you paid during the year, along with the underlying contracts or agreements. Consult your accountant about the deductibility of any specific expense; the list above is educational, not tax advice.

Where Owners Go Wrong: The Four Most Costly Preparation Mistakes

Most appointment problems trace back to one of four preparation errors. None of them are unusual, and all of them are preventable.

Mistake 1: Bringing software reports but not source documents. QuickBooks and similar tools produce a clean Profit and Loss statement, but that report only reflects what was entered. Bank statements and original receipts are the documents that substantiate each line. If your numbers do not reconcile to your bank statements, your accountant must stop and investigate before filing. That investigation is billed time.

Mistake 2: Mixing personal and business finances. SCORE research identifies this as the single most common gap accountants find during new-client onboarding. When personal and business transactions run through the same account, the CPA must manually sort and reclassify each one. That process can add hours to your bill and increases the risk that legitimate business expenses are misclassified or missed.

Mistake 3: Forgetting estimated tax payment records. Self-employed owners and LLC members who made quarterly estimated payments to the IRS and Michigan Department of Treasury during the year must bring proof of those payments. Without documentation, the completed return may show a balance due for amounts you have already paid, creating a filing error that requires correction.

Mistake 4: Showing up without a plan when books are not in order. Arriving at a tax appointment with unreconciled books, missing months of transactions, or no organized expense records shifts the appointment from tax preparation to bookkeeping cleanup. That work has to happen either before or after the meeting. If you know your books aren't in order before your meeting, address it in advance. The cost of a cleanup session before your appointment is almost always lower than the cost of delayed filing or a follow-up meeting. Amended returns triggered by documents discovered after an initial filing create additional processing delays and rework that are almost always avoidable with complete preparation from the start.

Frequently Asked Questions

Do I need to bring physical receipts, or will my accounting software reports be enough?

Software reports summarize your transactions but do not prove them. Bank statements and original receipts are the source documents that substantiate what your accounting software shows. Your accountant needs both layers to file accurately and to protect your deductions if the IRS ever questions a return.

What if I do not have my prior-year tax return because I switched accountants?

You can request a transcript of your prior-year return directly from the IRS through the IRS online transcript tool. A prior-year return is essential for verifying carryover items such as net operating losses and depreciation schedules. Request the transcript as early as possible so it does not delay your appointment.

How far back should I keep my business tax records?

The IRS general rule is at least three years from the date you filed the return. That window extends to seven years if the return involved a bad-debt deduction or worthless securities. Michigan may have its own retention requirements that differ from federal rules, so ask your accountant what applies to your specific situation.

I use my personal vehicle for business. What exactly does my mileage log need to include?

IRS Publication 463 requires your mileage log to include the date of each trip, the destination, the business purpose, and the miles driven. A verbal estimate or round number is not sufficient, and the deduction can be disallowed entirely in an audit if the log is missing or incomplete. Several free mobile apps can log trips automatically and produce a report that meets IRS standards.

I paid quarterly estimated taxes during the year. Do I need to bring proof of those payments?

Yes. Bring payment confirmations, bank records, or screenshots from your IRS Online Account showing each payment made. Without this documentation, your completed return may incorrectly show a balance due for amounts you have already paid. If you made quarterly estimated payments to the Michigan Department of Treasury, document those separately as well.

What should a first-time client bring that a returning client does not?

First-time clients should bring at least two prior years of federal and state returns, any existing depreciation schedules from a previous accountant or software file, their EIN confirmation letter (IRS Form CP 575), and business-formation documents such as Articles of Organization or an operating agreement. Documentation of all estimated payments made to both the IRS and the Michigan Department of Treasury during the current year is also essential.
