Al Capone and money laundering: where the term comes from

Three dates settle most of what gets repeated about Al Capone and money laundering.

17 October 1931. A federal jury in Chicago returns its verdict: Capone is guilty of income tax crimes.

June 1973. A Senate committee investigating Watergate asks witnesses about "laundering checks".

27 October 1986. The Money Laundering Control Act makes laundering a federal crime.

The word reached print 39 years after the verdict, and the crime came 55 years after it. Laundering means making criminal money look as if it came from a lawful source, so it can be banked and spent. In 2026 that work runs through money laundering methods and typologies such as structured cash deposits, false trade invoices and crypto transfers.

Why is it called money laundering?

Money is called laundered because it goes in dirty and comes out looking clean. To launder money is to wash its criminal source out of the record, so it can sit in a bank, buy property or pay wages as if it had been earned lawfully.

The law adds a state of mind to the picture. The legal definition of money laundering asks for knowledge, or in some laws suspicion, of where the property came from. In the US, 18 U.S.C. 1956 asks that the person know the property "represents the proceeds of some form of unlawful activity".

The 1973 Senate hearings show the image at work. The committee's chairman asked whether checks received by a campaign committee had been sent to someone near Washington, converted into cash and returned to the committee. Cash that comes back that way no longer shows which donor wrote the check.

When was the term money laundering first used?

The Oxford English Dictionary's earliest evidence for "money launderer" is from 1970, in the Harlowton (Montana) Times. For "money laundering" it is from 1973, in the Morning Call of Allentown, Pennsylvania. It gives dates, not a coiner. These are the earliest uses the dictionary holds as of November 2026.

By the summer of 1973 the word had reached a Senate hearing room. On 7 June 1973 the committee investigating Watergate asked the campaign committee's treasurer what the expression "laundering checks" meant, as the printed hearing record shows. The treasurer had read the term many times but had no precise knowledge of it.

Six days later the committee went through $89,000 in Mexican checks and a $25,000 check, all of which had cleared through the bank account of one of the Watergate burglars. Capone had died on 25 January 1947, 23 years before the dictionary's first example.

Did Al Capone launder money through laundromats?

No primary record shows that Capone did.

Table 1. What is repeated about Capone and money laundering, and what the record shows (as of November 2026)

The grain of truth sits in the FBI's history of the case, which says the mob developed interests in cleaning and dyeing businesses. That account links them neither to the word nor to Capone's own income, and the tax investigators found no property in Capone's name at all. The National Archives adds that Capone was never convicted under the National Prohibition Act. The charge was income tax evasion.

How did Al Capone make and move money?

Capone's income came from gambling, houses of prostitution and bootlegging, according to the IRS special agent's report of 21 December 1933. The same report shows how the money moved, and almost none of it went through a bank in Capone's name.

"The defendant had no bank accounts, kept no book records of activities", the report says. No property was bought under Capone's own name either. Apart from Western Union wires and an occasional check, every dealing was in currency. Income arrived as cash, sometimes as checks and often by wire. One exhibit listed $72,380 in Western Union transfers, sent by members of the organization to Capone or Capone's agents at the winter home in Miami.

The gambling houses did bank, just not in Capone's name. A cashier's sworn statement in the report says the Cicero gambling house kept its account at the Pinkert State Bank in its manager's name. Another cashier described accounts at the same bank under assumed names, used for the gambling business. Profits went to the organization's representative as cashier's checks from that bank.

Spending left its own trail. At the Chicago hotel where Capone kept a suite, the bills were paid about once a week and usually came to $1,200 to $1,500. A rent bill of about $3,000 was paid the next day in currency from a roll of bills.

The government's figure for Capone's net income from 1924 to 1929 was $1,038,655.84. It is the income the tax case could prove. The report calls the evidence behind it "largely circumstantial in character".

With no account to examine, the investigators built the case from a gambling house's ledger and from what Capone spent. In a bank's data today, the same habits would show up as large cash deposits, wires from several senders to one person and an account held in someone else's name. complead, formerly Sanction Scanner, lets a compliance team write each of those patterns as a transaction monitoring rule, with conditions and thresholds the team sets itself.

How was Al Capone caught?

Through tax. On 16 May 1927 the Supreme Court held in United States v. Sullivan that gains from illicit traffic in liquor were subject to the income tax, seeing no reason "why the fact that a business is unlawful should exempt it from paying the taxes that if lawful it would have to pay." Criminal income had to be reported like any other.

Deliberately evading tax on it is tax fraud, and the IRS manual says tax fraud requires both "a tax due and owing" and "fraudulent intent".

The proof came from a ledger. On 26 April 1926 police raided Capone's gambling house in Cicero and found its book of daily entries in the safe. No tax case was pending, so the book was filed away unused. The investigator who wrote the report later found it by chance among papers left by an agent who had resigned. Its entries showed a net profit of $300,250.94 for 1924, and 41 percent of that, or $123,102.89, was charged as Capone's own income for the year.

A secret grand jury indictment of 13 March covered tax on that 1924 income, and a June indictment held 22 counts for 1925 to 1929. Capone pleaded guilty to every count on 16 June. On 1 August the court allowed the pleas to be withdrawn and set trial for 6 October. The verdict came on 17 October.

What was Al Capone convicted of, and what was the sentence?

The jury acquitted Capone on indictment No. 22852. On No. 23232, the 22 count indictment, it returned guilty verdicts on counts 1, 5, 9, 13 and 18 only. Counts 1, 5 and 9 were felony attempts to evade tax for 1925 to 1927, and counts 13 and 18 were misdemeanors for failing to file a return for 1928 and 1929.

The judgment of 24 October 1931 set five years and a $10,000 fine on each felony count. Each misdemeanor drew one year in the county jail and a $10,000 fine. Because some terms ran together, the total came to 11 years, $50,000 in fines and the costs of prosecution, which the National Archives puts at $7,692.

Capone went to the federal penitentiary in Atlanta, then to Alcatraz for four and a half years. Release came on 16 November 1939, after seven years, six months and 15 days, with all fines and back taxes paid.

When did money laundering become a crime?

In the United States, on 27 October 1986. Before that date, laundering money wasn't a federal offense of its own.

Table 2. The rules behind money laundering as a crime, 1927 to 1990

The 1970 law is the Bank Secrecy Act, enacted on 26 October 1970. It made banks report large cash transactions to the government, and laundering itself became a federal crime only 16 years later.

The 1986 act closed that gap. FinCEN's history of the laws lists four changes, and the first two are that the act "Established money laundering as a federal crime" and "Prohibited structuring transactions to evade CTR filings".

Other countries followed through treaties and standards. The UN Office on Drugs and Crime notes that the 1988 Vienna Convention addressed laundering in article 3. The G7 set up the FATF in 1989 to develop anti money laundering measures, and in April 1990, less than a year later, it issued its Forty Recommendations.

Two of the biggest money laundering scandals on record, at Danske Bank's Estonian branch and at HSBC with its Mexico affiliate, ran through banks from 2006 onward, two decades after the 1986 act.

What would a compliance team see in Capone's money today?

Read the 1933 report the way your monitoring team reads a customer file in 2026, and seven patterns stand out. Each item pairs a habit the report documents with a control a bank runs today, as an illustration.

1. Cash over $10,000. Capone dealt in currency. Today a US bank files a currency transaction report on any cash transaction over $10,000.
2. Cash split to stay under the line. Breaking cash into smaller deposits to avoid that report is structuring, a crime since 1986. A rule that totals a customer's cash per day and per week reads it.
3. A business that banks in someone else's name. The Cicero gambling house banked in its manager's name and under assumed names, and moved profits as cashier's checks. The question is who the ultimate beneficial owner of the account is, and whether the named holder is acting for someone else.
4. Several senders, one recipient. Members of the organization wired money to Capone or agents in Miami. A money transmitter's monitoring links senders who pay the same person and asks why they do.
5. Spending with no declared income. Capone's hotel bills ran to $1,200 to $1,500 a week, and no tax return was ever filed for the years charged. When spending outruns any income on record, the bank asks for the customer's source of funds and source of wealth.
6. Takings that outrun the trade. One gambling house booked $300,250.94 in net profit in the eight months from May 1924. A cash business whose deposits outgrow its size, hours or sector gets a closer review.
7. Moving crime proceeds to evade tax. Under 18 U.S.C. 1956(a)(1)(A)(ii), a person who knowingly moves the proceeds of a specified unlawful activity, aiming at tax evasion or a false return under sections 7201 or 7206 of the tax code, is laundering money today.

Each pattern opens a review. Your analyst reads the alert, weighs it against what the customer said at onboarding, and decides whether a report is due.

What changed in 2026 for the laws that came after Capone?

1. 10 April 2026. FinCEN proposed a rule to "fundamentally reform" what AML/CFT programs at financial institutions must contain.
2. 3 September 2026. The FATF reported on professional laundering through underground banking and hawala. More than 80 percent of reporting jurisdictions named these systems among the principal channels, a trade the FATF calls "money laundering as a service". Capone's money moved through the organization's own members, while the 2026 report is about launderers who sell the work to others.
3. 13 October 2026. Bank of America admitted willful violations of the BSA, the 1970 law in Table 2. FinCEN assessed a $1.2 billion penalty, and the OCC's own civil money penalty came to $750 million.

Capone's case leaves a question compliance teams still get asked: is tax evasion money laundering? Under the clause in item 7 of the list above, the two meet when the money moved is already the proceeds of a specified unlawful activity and the move is meant to evade tax.
