Here’s what HIVE AI had to say about “What documents are “essential” for filing a return in 2025?”:
Essential documents for filing a 2024 federal return in 2025

Identification and taxpayer information

  • Photo ID for you (and spouse, if filing jointly)
  • Social Security numbers or ITINs for everyone on the return (taxpayer, spouse, dependents)
  • Birthdates for all persons listed on the return
  • If you use an ITIN, confirm it’s valid; expired ITINs can delay processing and refunds. The IRS accepts returns with expired ITINs, but renewal may be needed for smooth processing

Wage and income documents

  • Form W-2 from each employer; employers must furnish/submit by January 31, so wait until you have them all
  • Forms 1099 series reporting income:
    • 1099-NEC (nonemployee compensation) — due to you by Jan. 31
    • 1099-MISC, 1099-DIV, 1099-INT, 1099-G, 1099-R, 1099-K, 1099-C, 1099-LTC, 1099-A, etc. — typically furnished by late Jan to March based on issuer deadlines; many file with IRS by Feb. 28 (paper) or Mar. 31 (e-file)
  • SSA-1099 for Social Security benefits
  • Brokerage/custodial tax documents (often consolidated 1099), and basis/digital asset summaries if applicable; brokers must report basis for covered assets including digital assets as the Secretary implements reporting under section 6045(g)
  • Records of digital asset transactions (crypto/NFTs): dates, amounts, proceeds, cost basis, fair market value in USD; keep these even if you didn’t receive a 1099

Health coverage statements

  • Form 1095-A (if you used the Health Insurance Marketplace) — needed to reconcile the Premium Tax Credit
  • Forms 1095-B/1095-C (if furnished) — useful for records; not required to attach but keep with your files. Issuers file these with IRS by Feb. 28 (Mar. 31 if e-file)

Deductions and credit support

  • Mortgage interest (Form 1098) and real estate tax records
  • Student loan interest (Form 1098-E) and tuition statements (Form 1098-T) with receipts for books/fees
  • Charitable contribution acknowledgments; special documentation is required for certain donations (for example, Form 1098-C or contemporaneous written acknowledgment for vehicle donations)
  • Child and dependent care provider details (name, address, SSN/EIN) and payment records
  • HSA/FSA contribution records and medical expense receipts if itemizing
  • Education credit documentation and teacher expense receipts
  • EITC/CTC/AOTC/Head of Household substantiation (residency, relationship, support, school records, etc.) retained in your files; preparers must document what they relied on (Form 8867 instructions)

Self-employment, gig, rental, and investment records

  • Business income records (invoices, 1099-NEC/1099-K, bank statements) and expense logs/receipts
  • Rental income and expense records
  • K-1s from partnerships, S corporations, and trusts
  • Basis and transaction reports for securities and digital assets; maintain complete records if third-party forms are incomplete

Bank and refund/payment information

  • Bank routing and account numbers for direct deposit of refunds
  • Estimated tax payment records and prior-year carryovers

Prior-year return and IRS account data

  • Copy of last year’s federal and state returns to ensure carryovers and consistency
  • IRS Online Account can display information returns (e.g., 1099s, 1095-A) as the IRS receives them; issuer due dates are generally Jan. 31 for 1095-A/1099-NEC and Feb. 28/Mar. 31 for many other forms
  • The IRS advises waiting to file until you have all necessary tax documents to avoid errors and delays; 2025 Tax Day is April 15

Special or less common attachments

  • Forms or statements the IRS cannot accept electronically must be mailed with Form 8453 if you e-file (for example, certain appraisals or section 6707A disclosures, charitable appraisals)
  • If using a paid preparer but you choose to file on paper, a specific taxpayer-signed statement is required documenting that choice

Timing cues and why they matter

  • Employers must furnish W-2s and payers must furnish certain compensation forms by January 31; filing before receiving them risks omissions and IRS mismatches
  • Many information returns are filed with the IRS by late February or March, and copies populate to your IRS Online Account thereafter—use this to verify completeness
  • The IRS explicitly advises waiting to file until you have all necessary documents to reduce errors and processing delays

Quick checklist you can use

  • Government IDs, SSNs/ITINs, birthdates
  • Prior-year tax return
  • W-2s; all 1099s; SSA-1099
  • 1095-A (if Marketplace coverage); 1095-B/C if provided
  • Mortgage interest (1098), property tax, charitable receipts, student loan (1098-E), tuition (1098-T)
  • Child/dependent care provider info and payments
  • HSA/FSA and medical expenses (if itemizing)
  • Business/gig/rental income and expense records; K-1s
  • Investment and digital asset transaction details and basis
  • Bank routing/account numbers; estimated payment history
