An inflation tax is a tax on cash. Inflation
reduces the real purchasing power of cash.
After inflation, holders of cash can buy
less with that cash. The decrease in what
can be purchased with a fixed amount of
cash is the tax paid on that cash.
Like all taxes, the inflation tax is a tax
imposed by government and the proceeds
go to pay for government expenditures. A
government initiates an inflation tax by
printing money to pay for goods and services
instead of raising sufficient revenue
through taxation or borrowing. As the
money stock grows relative to the production
of goods and services, prices rise,
leaving households and businesses poorer
to the extent that they hold cash balances
representing less purchasing power. If the
inflation rate is 10 percent, then an individual
holding $1000 cash for a year is
taxed at a rate of 10 percent on that cash.
Like any property tax, households and
businesses can avoid the inflation tax by
not holding cash. Economists theorize
that there is an optimum inflation rate at
which the tax revenue from the inflation
tax reaches a maximum. Inflation rates
beyond the optimum rate cause cash
holdings to shrink to the point that tax
revenue from the inflation tax contracts
in terms of real purchasing power. At
lower inflation rates, households and
businesses are more willing to pay the
inflation tax, regarding it as a necessary
expense to enjoy the convenience of
holding cash.
The inflation tax can generate government
revenue in other ways. By
pushing taxpayers into higher tax
brackets, the inflation tax brings in
additional tax revenue. In addition,
inflation reduces the real, inflationadjusted
amount of debt that a government
owes. Usually, no additional tax
collectors and mechanisms are needed
to collect the inflation tax.
Critics observe that the inflation tax is
taxation without consent. Without any
kind of legislative approval or even public
announcement of a tax increase, the government
increases the tax burden on
citizens. Critics also cite the numerous
negative effects of inflation.
Economists seemed to have known
about inflation tax for several centuries
but paid it little attention until the 20th
century, when paper money begin to
dominate monetary systems. The famous
20th-century economist John Maynard
Keynes credited Rome with discovering
the power of taxation through currency
depreciation. In 1922, Keynes gave the
first full treatment in English of the inflation
tax. In his article, “Inflation as a
Method of Taxation,” Keynes hinted that
the Soviets preceded him in regarding
inflation as an instrument of taxation.
Evgeni Alexeevitch Preobrazhensky
(1886–1937), a Soviet economist, wrote
the book Paper Money in the Epoch of
Proletarian Dictatorship, published in
Russian in 1920, predating Keynes’s article.
Preobrazhensky argued that inflation
was a highly effective policy for diverting
resources from the private to the
socialized sector and for expropriating the
money capital of the bourgeoisie. One
often quoted line from Preobrazhensky’s
book on paper money referred to the
printing press as “that machine gun
which attacked the bourgeois regime in
the rear.”
The idea of inflation as a tax on cash
balances caught on rapidly in the United
States following World War II. It gave a
rationale for a government that seemed a
bit complacent in combating inflation.
The Nobel Prizing economist Milton
Friedman broached the subject first in
his book Essays in Positive Economics,
published in 1953. By the 1980s, the
idea had entered into political debate,
and “inflation tax” became a household
phrase.
