Tax records must support the income, deductions and credits claimed on returns. Taxpayers need to keep these records if the IRS asks questions about a tax return or to file an amended return. It is even more important for taxpayers to have a copy of last year’s tax return as the IRS makes changes to authenticate and protect taxpayer identity.
How long do you have to keep tax records?
You must maintain your records for as long as your return is subject to audit by the IRS. Typically, you only need to keep your documentation around for three years from when you filed.
Do you need a hard copy of a tax receipt?
Issued as a Revenue Procedure, the rules stipulate that as long as certain concerns are addressed, the IRS would treat electronic records the same as written records. The electronic storage system must provide a way for an auditor to check whether records had been altered, and be able to produce a legible hard copy from the file.
Do you have to have a scanned copy of your tax return?
Your scanned copies must be legible and readable, and the auditor must be able to print it. Unlike written records, electronic records can readily be altered without a trace. Qualifying storage systems must keep an audit trail that shows when and how the documents were altered.
How can I request a copy of my tax return?

When do you need to keep your tax records?
Taxpayers should keep these — as they do other tax records — generally for three years after they file their tax returns. Whether stored on paper or kept electronically, the IRS urges taxpayers to keep tax records safe and secure, especially any documents bearing Social Security numbers.
How many years back does the IRS keep tax returns?
The instructions for the 4506T are attached, but the bad news here is that only 10 years are available per the Inst. You might consider asking for the free 10 years of transcript info, at least that gets you back to where the max contribution was only $2,000. Re: How far back does the IRS keep tax returns?
