How Do You File a Tax Return for a Previous Year?

If you missed a tax filing deadline, you can generally still file the return for that previous year. Whether you are one year behind or have several years of unfiled returns, addressing past-due filings can help bring your tax records back into compliance.

The process is similar to filing a current return, but prior-year returns can involve additional challenges, including locating old tax documents, using the correct year's tax forms, and determining whether taxes, penalties, or interest are owed.

Can You Still File an Old Tax Return?

Yes. A missed filing deadline does not prevent you from preparing and submitting a prior-year tax return.

You should prepare the return using the tax laws, forms, income, deductions, and credits applicable to that specific tax year.

For example, a return for an earlier year should be prepared using the rules and information that applied during that year rather than current-year tax rules.

Start by Determining Which Returns Are Missing

Before preparing anything, identify exactly which tax years need to be filed.

If you are several years behind, it can help to organize the returns chronologically and determine what information is available for each year.

You may need documents such as:

• W-2s

• 1099s

• Business income and expense records

• Investment records

• Mortgage and property records

• Retirement income documents

• Other tax-related statements

Having complete records can help ensure each prior-year return is prepared accurately.

What If You're Missing Tax Documents?

Missing documents are common when preparing older returns.

You may be able to obtain copies from employers, financial institutions, investment providers, or other organizations that originally issued them.

IRS wage and income transcripts may also provide information reported to the IRS by third parties.

For business owners, additional work may be necessary to reconstruct income and expenses from bank statements, bookkeeping records, receipts, and other financial information.

What If You Owe Taxes for a Previous Year?

If a prior-year return shows a balance due, penalties and interest may apply depending on the circumstances.

Waiting longer to file can potentially increase the amount owed.

Even if you cannot pay the entire balance immediately, filing the required return and then evaluating payment or tax-resolution options may be preferable to continuing to leave the return unfiled.

What If You're Due a Refund?

You may still be able to claim a refund from a previous year, but refund claims are subject to statutory time limits.

Waiting too long to file can potentially result in losing the ability to receive a refund that otherwise would have been available.

If you believe an older unfiled return may produce a refund, it can be particularly important to determine whether the applicable deadline is approaching.

Can You File Several Years at Once?

If you have multiple unfiled tax years, each year generally requires its own separate return.

A CPA can help organize the missing years, gather the necessary information, prepare each return using the appropriate rules, and determine whether there are additional IRS issues that need to be addressed.

What If the IRS Already Contacted You?

If you have received an IRS notice regarding an unfiled return, review it carefully.

The IRS may have information indicating that a return should have been filed, and ignoring correspondence can potentially lead to additional complications.

In some circumstances, the IRS may prepare a Substitute for Return based on information available to the agency. That calculation may not include all deductions, credits, or other information that could have been reported on a properly prepared return.

Should You File the Most Recent Year First?

When several returns are missing, the best filing strategy depends on your circumstances.

Rather than guessing which year to address first, it can be helpful to identify all outstanding filing requirements and develop an organized plan for bringing the returns current.

This also provides a clearer picture of the total amount owed or any potential refunds across multiple years.
