How Inflation is Like a Tax

1. Erosion of Purchasing Power

Inflation reduces the real value of money — that is, what your dollars can buy.

  • When prices rise, the same amount of cash buys fewer goods and services.
  • This loss of purchasing power acts like a hidden tax on cash holdings and fixed incomes.
  • For example, if inflation is 5%, and your savings earn only 2%, your real wealth effectively shrinks by 3% — similar to being taxed at that rate.

2. Redistribution from Savers to Borrowers (Including Government)

Inflation benefits borrowers at the expense of lenders.

  • Debts are repaid in money that is worth less than when it was borrowed.
  • Because the government is one of the largest debtors, inflation reduces the real value of its outstanding debt — effectively transferring wealth from private citizens (bondholders, savers) to the state.
  • This transfer resembles a tax that funds government obligations without explicit legislation.

3. Bracket Creep and Nominal Taxation

In a nominal (non-inflation-adjusted) tax system, inflation can push people into higher tax brackets or inflate nominal income and capital gains without increasing real income.

  • This increases tax revenue even though people are not wealthier in real terms.
  • Thus, inflation can raise effective tax burdens invisibly — a phenomenon called bracket creep.

4. Hidden and Regressive Effects

Like many indirect taxes, inflation tends to hurt those with fixed or lower incomes more than wealthier individuals.

  • Those with few assets or no access to inflation-protected investments suffer the most.
  • It is “hidden” because it does not appear as a line item on a paycheck or bill, yet erodes living standards.

5. Inflation as a Form of Seigniorage

When governments or central banks create new money to finance spending, they gain purchasing power before prices adjust — known as seigniorage.

  • The public bears the cost later as prices rise.
  • This is functionally equivalent to the government collecting a tax through money creation.

Example: Inflation as a 5% “Tax” on Savings

You have $10,000 in a savings account earning 2% annual interest.
During the same year, inflation is 5%.

Step 1. Nominal Return (What You See)

  1. Bank interest: 2% × $10,000 = +$200
  2. End of year balance: $10,200

At first glance, it seems you’ve earned $200 — a gain.


Step 2. Real Value After Inflation (What You Get)

Since prices rose 5%, your $10,200 now buys what $9,714 would have bought a year ago.
(Calculated as $10,200 ÷ 1.05 = $9,714)

That means in real purchasing power, you’ve lost $286.


Step 3. The “Hidden Tax”

Even though you paid no explicit tax, inflation effectively reduced your wealth by:

$286 ÷ $10,000 = 2.86%

So the “real return” on your savings is:

2% nominal interest – 5% inflation = –3% real return

That 3% loss functions exactly like a 3% wealth tax on your savings — imposed silently through inflation.


Suppose the government prints new money equal to 5% of the money supply to fund spending.

  • The government gains new purchasing power immediately.
  • The public later pays through higher prices.
  • The real value of all existing money falls by about 5%.

From the government’s perspective, that’s revenue — just as if it had collected a 5% tax on everyone’s cash holdings.
