A first appointment with a tax preparer goes faster when the documents arrive with the taxpayer. The core set is identification, income statements, deduction records, last year's return, and bank details for a refund. What is missing usually matters more than what is brought — a single absent form can hold up a return for weeks.
What does every preparer need to see?
Four categories cover most engagements, regardless of how complicated the return turns out to be.
- Identification — a government photo ID, plus Social Security cards or ITIN letters for the taxpayer, spouse and every dependant claimed. Preparers verify the numbers rather than trusting a recollection, because a transposed digit rejects the return.
- Income statements — Forms W-2 from every employer worked for during the year, and the 1099 series for everything else: 1099-NEC for contract work, 1099-K for payment-app and marketplace receipts, 1099-INT and 1099-DIV for interest and dividends, 1099-B for securities sales, 1099-R for retirement distributions, SSA-1099 for Social Security.
- Last year's return — it carries forward the information a new preparer cannot reconstruct: carryover losses, depreciation schedules, prior elections, state credits.
- Bank account and routing numbers — for direct deposit of a refund or direct debit of a balance.
Which records get forgotten most often?
Predictably, the ones that arrive outside an envelope marked tax document. Interest earned in an account that went paperless. A brokerage that posts its consolidated 1099 online only. A side income stream that never generated a form at all — cash work, or platform earnings below a reporting threshold, both of which are reportable regardless of whether a form was issued.
Records supporting deductions and credits are the other gap, because they are generated by the taxpayer rather than sent to them:
| Category | Typical records |
|---|---|
| Homeownership | Form 1098 mortgage interest, property tax statements, closing documents from a purchase or sale |
| Charitable giving | Receipts and acknowledgment letters; records of non-cash donations |
| Medical | Out-of-pocket payment records, insurance statements, Forms 1095 |
| Education | Form 1098-T, Form 1098-E, records of books and required materials |
| Childcare | Provider name, address, taxpayer identification number, amounts paid |
| Self-employment | Income and expense ledger, mileage log, home-office measurements, asset purchases |
| Estimated payments | Dates and amounts of federal and state payments already made |
The childcare row is worth singling out: the credit requires the provider's identification number, and chasing it after the appointment is a common cause of delay.
What changed in the taxpayer's life this year?
The question sounds like small talk and is not. Life events drive most of what differs from last year's return, and a preparer who is not told cannot ask the follow-up. Marriage or divorce. A birth, an adoption, or a dependant who aged out. A move — particularly across a state line, which can mean two state returns. A house bought or sold. A job change, a redundancy payment, or unemployment compensation. Retirement, or a first required distribution. A business started or closed. A person supported financially who does not live in the household.
An IRS Identity Protection PIN belongs on the list too, if one has been issued: the return will reject without the current year's number.
What should a taxpayer expect to be asked for in return?
The obligations run both ways. Anyone paid to prepare a federal return must hold a current PTIN and must sign the return they prepared, and credentials — CPA, enrolled agent, attorney — are publicly verifiable; how to verify a tax preparer sets out that check in full.
An engagement letter setting out scope, fee basis and responsibilities is normal practice for a credentialed preparer, and it protects both parties. So does a preparer who asks questions that seem intrusive: due-diligence requirements for credits like the EITC oblige them to enquire and to document the answers.
Where to get help
Taxpayers comparing preparers for a first engagement, or replacing one, can review credentialed practitioners through the recognized professional bodies for the United States. Verifying a credential and a PTIN before handing over documents takes minutes and is the single highest-value check available.
