Books and records retention calculator
Pick the firm type and the record, enter the date the rule counts from, and get the keep-until date, the earliest day the record may go, and the first-years window the rule names. The SEC record retention requirements for advisers and the FINRA record retention requirements for broker-dealers set different periods and start them on different days; the tool keeps them apart and says plainly where a rule is silent.

Pre-filled with an example: an adviser’s client email last written on March 14, 2026, with a December 31 fiscal year end.
Letters and emails on recommendations, funds or securities received or delivered, orders, and performance (204-2(a)(7)).

What it computes
Three answers for one record: the date the retention period starts, the date it ends (the keep-until date, with the day after it as the earliest the record may go), and the end of the first-years window, when the rule names one. Pick the firm type first, because the two rulebooks never share a period. An adviser’s records follow Advisers Act Rule 204-2; a broker-dealer’s follow Exchange Act Rule 17a-4, which FINRA Rule 4511 requires members to meet.
- Advisers count from the end of the fiscal year in which the last entry was made17 CFR 275.204-2(e)(1)
- Broker-dealer blotters, ledgers and communications: the rule gives a length but no start day17 CFR 240.17a-4(a), (b)
- Some records count from an event: an account closing, a report date, a manual retired17 CFR 240.17a-4(c), (e)
The two windows are not the same thing. Rule 204-2 keeps most adviser records in an easily accessible place for the whole five years and the first two of them in an appropriate office of the adviser. Rule 17a-4(a) and (b) keep blotters, ledgers, confirmations and communications for six or three years, the first two in an easily accessible place; the event-based records in 17a-4(e) stay easily accessible throughout. Where the records live, and how they are stored, is a separate question: the 17a-4(f) storage conditions bind broker-dealers only, and the archiving requirements matcher sorts out which channels must be captured at all.
A firm registered as both an adviser and a broker-dealer works out each record under the rule that makes it required. Rule 204-2(h)(1) lets a record kept under 17a-3 and 17a-4 that is “substantially the same” as the adviser record count for 204-2. To list which records your firm must make in the first place, start with the books and records checklist generator.
Worked example
Take the tool’s own default. An adviser with a December 31 fiscal year end last wrote to a client about a recommendation on March 14, 2026. The email is a written communication under Rule 204-2(a)(7), so it follows 204-2(e)(1): five years “from the end of the fiscal year during which the last entry was made.” The fiscal year closes on December 31, 2026, so the record is kept until at least December 31, 2031, and in an appropriate office of the adviser through December 31, 2028. The same email sent from a broker-dealer would fall under 17a-4(b)(4) instead: three years, the first two easily accessible.
Seven records, counted by the rule text
| Record | Date entered | Period starts | First window ends | Keep until at least |
|---|---|---|---|---|
| Adviser: client email (204-2(a)(7)) | Mar 14, 2026 | Dec 31, 2026 | Dec 31, 2028 | Dec 31, 2031 |
| Adviser: ledger, June 30 year end (204-2(a)(2)) | Aug 10, 2026 | Jun 30, 2027 | Jun 30, 2029 | Jun 30, 2032 |
| Adviser: advertisement last disseminated (204-2(e)(3)(i)) | Oct 22, 2026 | Dec 31, 2026 | Dec 31, 2028 | Dec 31, 2031 |
| Broker-dealer: trade confirmation (17a-4(b)) | Mar 14, 2026 | Mar 14, 2026 | Mar 14, 2028 | Mar 14, 2029 |
| Broker-dealer: blotter entry (17a-4(a)) | Mar 14, 2026 | Mar 14, 2026 | Mar 14, 2028 | Mar 14, 2032 |
| Broker-dealer: account closed (17a-4(c)) | May 1, 2026 | May 1, 2026 | None named | May 1, 2032 |
| Broker-dealer: unusual-activity report (17a-4(e)(8)) | Jan 15, 2026 | Jan 15, 2026 | None named | Jul 15, 2027 |
17 CFR 275.204-2(e)(1), (e)(3)(i); 17 CFR 240.17a-4(a), (b), (c), (e)(8)
Two things in the table are worth a second look. The June 30 adviser counts from June 30, 2027, because an August 2026 entry falls in the fiscal year that ends then; a later fiscal year end pushes every date out. And the advertisement counts from the year it was last disseminated, not from the year it was first used, so an ad that stays in use keeps pushing its own start date out.
The rule text
The calculator turns on three sentences, one from each rulebook. Every period in the tool is one of these, or a paragraph that sets its own.
Note what the second sentence leaves out. Rule 204-2 names the day an adviser’s five years start; Rule 17a-4(a) and (b) name the length and the first-two-years window but no start day. Rule 4511(c) adds that FINRA records are kept “in a format and media that complies with SEA Rule 17a-4.” Before you act on a date, check it with your compliance counsel; the tool is a reading of the rule text, not legal advice.
Where the rule says so
Every record type in the tool, with the rule’s own words and the paragraph to cite. Open a row to read it. The full text is on the eCFR for Rule 204-2 and Rule 17a-4, and in FINRA’s rulebook for Rule 4511.
