How Long to Keep Brokerage and Investment Statements

Brokerage statement retention at a glance

The IRS period of limitations is generally 3 years from filing, 6 years if income was underreported by more than 25%, 7 years for a worthless securities or bad debt claim, and unlimited if no return was filed. See how long to keep bank statements for the same rules applied to bank accounts.

Why interim statements can usually go

FINRA Rule 2231 requires brokers to send customer account statements at least quarterly, and many send them monthly. Those statements are useful during the year for catching unauthorized trades or errors, but most of their content is repeated on the year-end statement and the consolidated 1099. Once you have checked that the year-end figures match your own records, the interim statements add little.

Exceptions: keep interim statements that are the only record of a purchase, a transfer in from another firm, a corporate action such as a split or spinoff, or a disputed transaction.

Cost basis: the record that matters most

Brokers report cost basis to the IRS on Form 1099-B for covered securities, which are generally stocks bought from 2011 onward and mutual funds and dividend reinvestment plan shares bought from 2012 onward, with later dates for certain bonds and options. For noncovered securities, such as older holdings or shares transferred in without basis information, the broker may report only the proceeds, and proving basis is your job.

Keep basis evidence for any position where:

• The shares were bought before the covered dates.
• The account was transferred between brokers and basis may not have followed.
• Dividends were reinvested over many years.
• The shares were inherited, gifted, or received in a corporate reorganization.

Without it, you may be unable to support your basis, and in the worst case the entire sale proceeds are treated as gain.

IRAs and retirement accounts

Retirement account statements matter less for annual taxes, because trades inside an IRA or 401(k) are not reported each year. What you must keep is proof of after-tax money: Form 8606 for nondeductible traditional IRA contributions, and records of Roth contributions and conversions. Those records determine how much of each future withdrawal is taxable, so keep them until the account has been fully withdrawn.

For accountants: working with client brokerage statements

Clients often arrive with a box of brokerage statements spanning many years, especially when basis is missing or an estate is being settled. Typing holdings and lots into a spreadsheet by hand is slow and error prone. A brokerage statement converter such as DocuClipper extracts holdings, quantities, market values, cost basis where the statement reports it, and the account summary into Excel, and checks the sum of positions against the statement's ending value. See converting brokerage statements for what is extracted.

How to store and dispose of investment records

• Download the year-end statement and all 1099s as PDFs every year and store them with that year's tax return.
• Keep a running basis file (one folder or spreadsheet per position) that survives broker changes.
• Shred or securely delete statements once they are past their retention date, because they contain account numbers and holdings.

FAQ

How long should I keep investment statements?

Keep monthly and quarterly statements until the year-end statement and 1099s arrive and agree. Keep year-end statements and 1099s for 3 to 7 years after filing, and keep purchase and cost basis records until you sell and the period of limitations for that year has passed.

Do I need to keep monthly IRA statements?

Usually not once the year-end statement arrives. Keep Form 8606 and records of nondeductible or Roth contributions and conversions until all money in the account has been withdrawn.

How long do brokerage firms keep statements?

Broker-dealers must keep customer account records for several years under SEC and FINRA rules, but you should not rely on the firm for old records. Download your year-end statements and tax forms every year.

How long should I keep mutual fund statements?

Treat them like other brokerage statements: keep the year-end statement and 1099s with your return, and keep purchase and reinvestment records until you sell the shares.
