Reconstructing Income for Years With No Records

The most common reason people give me for not filing is not money. It is paperwork. "I don't have the records, so I can't file." Then a year goes by, and another, and the pile of missing paperwork grows.

Here is the truth. You almost never need the original shoebox to file an accurate return. You need evidence, and evidence exists in more places than you think. The IRS reconstructs income all the time when taxpayers do not provide records. You can do the same thing, more accurately, because you know what the deposits were.

Why reconstruction is required, not optional

IRC 6001 requires every person liable for tax to keep records sufficient to show whether they are liable. Losing records does not suspend the filing requirement. And if you do not file, the IRS will build its own version from the information returns it has, with almost nothing on the deduction side. See how the IRS builds a substitute for return.

So the real choice is not between filing with records and not filing. It is between your reconstruction and the IRS's.

Step one: find out what the IRS already knows

Start with IRS wage and income transcripts. According to the IRS, the wage and income transcript "shows data from information returns we receive such as Forms W-2, 1098, 1099, and 5498," and it is "available for the current and nine prior tax years."

Two limits to know. The transcript only shows information returns that were actually filed with the IRS. And it is limited to approximately 85 income documents; if you have more, the IRS says the transcript will not generate through the online account. We cover transcripts in detail in using wage and income transcripts for late returns.

Every item on the transcript must be accounted for on your return. Either it goes on the return, or you have a documented reason it does not belong.

Step two: rebuild deposits

For wage earners, the W-2 usually tells the whole story. For the self-employed, people paid in cash, or anyone with multiple income streams, the bank account is the best witness.

The IRS's own examination manual explains how it uses bank records. In the bank deposits and cash expenditures method, total deposits "include amounts deposited from both taxable and nontaxable sources to all bank/financial accounts (both business and personal) maintained or controlled by the taxpayer," including savings and loans, brokerage houses, and credit unions (IRM 4.10.4.5.4.3). Gross receipts are then figured by adding deposited funds, funds spent without being deposited, and funds accumulated without being deposited, and subtracting nontaxable receipts and duplicated deposits (IRM 4.10.4.5.4.4).

You can use the same logic:

1. Get statements for every account you used during the year, business and personal.
2. Total the deposits for the year.
3. Remove transfers between your own accounts so they are not counted twice.
4. Remove non-taxable deposits, such as loan proceeds, gifts, insurance reimbursements, and returns of your own money.
5. Add income you received but did not deposit, such as cash you spent directly.
6. What remains is your best estimate of gross receipts, supported by bank evidence.

Ask each bank how far back it can provide statements and whether it charges for them. Request them early, because retrieval can take time.

Step three: separate non-taxable money and prove it

This is where reconstructions succeed or fail. The IRS manual lists the taxpayer defenses to an indirect income computation, and two of them are that the unexplained difference came from a non-taxable source, or from cash on hand or funds accumulated in prior years (IRM 4.10.4.5.8.2 and 4.10.4.5.8.3).

The manual also notes that examiners should establish cash on hand early, and that the "after-the-fact 'cash in the mattress' defense cannot be used if the actual cash-on-hand and accumulated funds have already been established." In plain English: if you claim a deposit came from savings, you need to show the savings existed, and you need to say so consistently from the start.

Document every non-taxable item:

• Transfers between your own accounts, matched on both sides
• Loan proceeds, with the loan documents
• Gifts and inheritances, with letters, estate papers, or the giver's statement
• Refunds and reimbursements, with the source documents
• Sale proceeds of personal property, with evidence of what was sold
• Redeposits of cash previously withdrawn

Step four: fill in what banks do not show

Some income never touches a bank. Some records cannot be recovered. For those gaps, look for other evidence:

• Client and customer records, such as invoices, contracts, or emails confirming payments
• Payment app and marketplace histories for prior years, where available
• Information returns you received but the IRS did not, such as a 1099 that was mailed to you but not filed
• Prior and later filed returns, which show the pattern of your income over time
• Third parties, such as a former employer's payroll department or a client's accounts payable

What not to do

Do not use averages. The IRS will not use industry averages on its own SFRs (IRM 4.12.1.25.2), and an examiner should "never determine income solely from statistical data" (IRM 4.12.1.6). If the IRS cannot build your return on averages, you should not either.

Do not leave out what the IRS knows. Omitting income that appears on your transcript is the fastest way to get your return pulled.

Do not under-report because the records are thin. A return signed under penalties of perjury that you know is false is a separate crime under IRC 7206(1). Thin records call for careful estimates backed by evidence, not convenient ones.

Wages, tips, and the easy cases

Not every reconstruction is hard. If your only income was wages, the W-2s on your wage and income transcript usually tell the whole story, including federal withholding. Add any income that does not appear there, such as cash tips or side work, and you may be most of the way to an accurate return.

Interest, dividends, retirement distributions, and many other items also arrive on information returns. The hard cases are self-employment, cash businesses, rental activity without good books, and investment sales where basis has to be rebuilt. Spend your effort where the uncertainty is, not where the IRS already has the answer.

Checking your reconstruction

Once you have a number, test it. Does the reconstructed income support the way you lived that year? Did you pay rent or a mortgage, buy a car, or travel? The IRS's own examination procedures look at whether reported income could support a taxpayer's spending, and IRC 7602(e) limits the use of financial status techniques to cases where there is a reasonable indication of unreported income. If your reconstructed income could not have paid your bills, something is missing, either income or a non-taxable source like savings or a loan. Find it before the IRS asks.

Keep a reconstruction file

For each year, keep a simple file showing how every number was built: the statements used, the deposit totals, each adjustment, and the evidence behind it. If the IRS ever asks how you arrived at a figure, you hand them the file. That file also protects you. It shows good faith, and good faith is the opposite of what the IRS is looking for when it screens non-filers for fraud.

When to bring in a lawyer first

If your reconstruction turns up large amounts of unexplained cash, accounts the IRS does not know about, or income from sources you would rather not discuss, stop. Those are exactly the facts the IRS fraud screening in IRM 25.1.7.2 is designed to find. Get legal advice about how and when to file before you finish the returns.
