For a mortgage application, you need every page of your federal Form 1040 for the most recent one to two tax years, along with all schedules and attachments filed with it, your W-2s or 1099s for the same period, and — if you own 25% or more of a business — the business entity’s tax returns as well. The pages of tax returns needed for a mortgage include blank pages: underwriters treat any missing page as a red flag, and a return that skips from page 2 to page 4 will be sent back until you produce page 3, even if page 3 was blank for your situation.
What follows is a page-by-page breakdown of what a lender expects to see, how it changes based on how you earn your income, and the loan-program differences in how many years you have to provide.
The 1040 and the Schedules That Travel With It
Form 1040 is the starting point. It summarizes your total income, deductions, and tax liability, and the underwriter uses it as the baseline for everything else in the file.1Internal Revenue Service. About Form 1040, U.S. Individual Income Tax Return On its own, though, the 1040 doesn’t tell the lender enough. The schedules behind it explain where the money came from and whether it’s likely to keep coming.
Include whichever of these you filed:
- Schedule A, if you itemized deductions.
- Schedule B, required when you reported more than $1,500 in interest or ordinary dividends. Lenders use it to verify investment income.2Internal Revenue Service. Instructions for Schedule B (Form 1040)
- Schedule C, which reports profit or loss from a sole proprietorship or freelance work. This is the single most scrutinized schedule for self-employed borrowers, because the net profit line drives their qualifying income.3Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business
- Schedule D, covering capital gains and losses. Lenders generally won’t treat a one-time stock sale as stable income; to count capital gains toward qualification, you typically need a pattern of gains over the last two years, and you may need supporting forms such as Form 4797 for business property sales or Form 6252 for installment sales.4Fannie Mae. B3-3.6-04, Income or Loss Reported on IRS Form 1040, Schedule D
- Schedule E, for rental property income, royalties, and pass-through income from partnerships and S corporations. It’s where the lender sees whether your rentals produce cash or lose money.5Internal Revenue Service. About Schedule E (Form 1040), Supplemental Income and Loss
When in doubt, send the entire return package exactly as filed. That is the standard the underwriter is measuring against.
How Many Years of Returns You Have to Provide
Two years of personal federal returns is the standard across most loan programs, with some room for one year on conventional loans.
For conventional loans backed by Fannie Mae, the file must always include the most recent tax return filed, with W-2s covering the most recent one or two years depending on the income type.6Fannie Mae. B3-3.1-02, Standards for Employment Documentation Fannie Mae’s Desktop Underwriter can sometimes issue a finding that permits only one year of personal returns for certain borrowers with stable, well-documented W-2 income. Self-employed borrowers should expect to provide two years in nearly every case.7Fannie Mae. B1-1-03, Allowable Age of Credit Documents and Federal Income Tax Returns
FHA loans have a firmer rule. The lender must obtain complete individual federal income tax returns for the most recent two years, including all schedules.8HUD. Mortgagee Letter 2022-09 This two-year history also applies to hourly, seasonal, overtime, and tip income, because FHA requires the lender to average those earnings over the full period.
VA-backed loans follow the same pattern. The Department of Veterans Affairs lists copies of federal income tax returns for the previous two years among the standard documents lenders request.9Department of Veterans Affairs. Cash-Out Refinance Loan
Business Returns If You Own 25% or More of a Business
If you own 25% or more of a business, your personal returns alone won’t be enough. Lenders need the business entity’s tax returns to verify that the company actually generates the income you’re claiming.
The form depends on the structure:
- Partnerships file Form 1065, which reports the entity’s total income and allocates each partner’s share through Schedule K-1.10Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income
- S corporations file Form 1120-S. Each shareholder receives a K-1 showing their share of income and deductions.11Internal Revenue Service. Instructions for Form 1120-S
- C corporations file Form 1120. If you own a C corp and draw a salary, the lender will review the corporate return to confirm the business can sustain your compensation.
Include every K-1 you received. Box 1 of the K-1 shows your share of ordinary business income, and Box 2 shows net rental real estate income or loss.12Internal Revenue Service. Instructions for Form 1065
FHA requires two years of business tax returns for self-employed borrowers. Fannie Mae generally does the same, though it allows an exception: if your individual returns show increasing self-employment income over two years, your closing funds aren’t coming from business accounts, and the loan isn’t a cash-out refinance, the lender may be able to skip the business returns.8HUD. Mortgagee Letter 2022-09
W-2s, 1099s, and Other Income Statements
Tax returns tell the lender what you reported. W-2s and 1099s tell the lender what your employers and payers reported independently. The underwriter cross-references these against your 1040, and unexplained mismatches can delay or derail your application.
Salaried and hourly workers include W-2 forms from each employer for the same period covered by their returns. Independent contractors provide Form 1099-NEC for non-employee compensation.13Internal Revenue Service. Form 1099-NEC and Independent Contractors Starting with payments made after December 31, 2025, the reporting threshold for 1099-NEC rises from $600 to $2,000. If you earned less than $2,000 from a particular client in 2026, you may not receive a 1099-NEC, but you still must report that income on your return. A lender seeing Schedule C income without a matching 1099 will likely ask for an explanation.
For investment income, include Form 1099-INT for interest and Form 1099-DIV for dividends.14Internal Revenue Service. About Form 1099-INT, Interest Income15Internal Revenue Service. About Form 1099-DIV, Dividends and Distributions Lenders use these to confirm the totals on your Schedule B and to see that the income is ongoing rather than a one-time event.
Signatures, Redactions, and Legibility
Every page must be present, legible, and unaltered. That includes pages with no data on them.
The returns must be signed. For paper-filed returns, that means a pen signature and date. For electronically filed returns, the lender will accept confirmation that the return was e-filed, a signed IRS Form 4506-C for the year in question, or IRS transcripts that validate the return.6Fannie Mae. B3-3.1-02, Standards for Employment Documentation The IRS recognizes several e-signature methods, including typed names, PINs, and stylus-captured signatures, so long as identity verification was completed through the tax software.16Internal Revenue Service. Frequently Asked Questions for IRS e-File Signature Authorization
Do not redact your Social Security number on documents submitted to the lender. Underwriters need the full SSN to match your returns against IRS transcripts and verify your identity. Redaction rules apply to court filings and public records, not confidential mortgage underwriting files.
How the Lender Confirms Your Returns With the IRS
Providing your returns to the lender is only half of it. The lender independently verifies them against IRS records, and that step surprises many borrowers.
The tool is IRS Form 4506-C, which authorizes the lender to request a transcript of your return through the IRS Income Verification Express Service (IVES).17Internal Revenue Service. Income Verification Express Service for Taxpayers You sign the form, the lender submits it through an authorized IVES participant, and the IRS returns a transcript showing the key line items from your filed return.18Internal Revenue Service. Form 4506-C, IVES Request for Transcript of Tax Return
A transcript is not a copy of your return. It’s a summary of line items as the IRS recorded them. The underwriter compares your borrower-provided return against the transcript, and if the numbers don’t match, that is an immediate problem. Common reasons for mismatches include filing an amended return that hasn’t fully processed, reporting errors, or providing the wrong year’s return. Expect to sign Form 4506-C at the beginning of the process, not the end.
Extensions, Amended Returns, and Unfiled Taxes
A filing extension changes what you can hand over. If you filed IRS Form 4868 for an automatic extension, Fannie Mae’s rules are strict from October 15 through April 14: the most recent year’s tax return is required and the use of a tax extension is not permitted during that window.7Fannie Mae. B1-1-03, Allowable Age of Credit Documents and Federal Income Tax Returns If you’re applying during that period, you’ll need to file before the lender can move forward. Outside that window, the lender may work with the extension and your prior-year returns, but expect the underwriter to require the extended return before final approval.
If you filed Form 1040-X to amend a prior return, provide both the amended return and the original. The lender will want to see what changed. The complication is processing time: the IRS generally takes 8 to 12 weeks to process an amended return, and sometimes up to 16 weeks.19Internal Revenue Service. Instructions for Form 1040-X Until the amendment is processed, the IRS transcript won’t reflect the corrected figures, and the transcript verification will show a mismatch. That alone can stall a loan for months. If you know you need to amend, file the 1040-X as early as possible before starting the mortgage process.
If you haven’t filed at all, expect the mortgage process to stop before it starts. Lenders cannot verify income through IRS transcripts if no return exists on file, and the 4506-C request will come back empty. You need to file the returns and let the IRS finish processing them before a lender can meaningfully underwrite the loan. This applies across conventional, FHA, and VA programs.
If You Owe Back Taxes
Owing back taxes doesn’t automatically disqualify you, but it creates additional hurdles, especially with FHA loans. FHA guidelines are explicit: borrowers with delinquent federal tax debt are ineligible for an FHA-insured mortgage.20HUD. FHA Single Family Housing Policy Handbook
The exception is a valid repayment agreement with the IRS on which you’ve made at least three months of timely payments. You cannot prepay three months’ worth of installments to shortcut the requirement. You’ll need documentation from the IRS showing the repayment plan and proof of the scheduled payments, and the monthly payment amount will be added to your debt-to-income ratio. Conventional and VA loans apply their own underwriting standards for tax debt, but the general principle holds: an unresolved tax lien is a serious obstacle, and a documented payment plan with a track record is the path through it.
