Do Lower Taxes Increase Government Revenue?

A system of taxation that is equitable for all taxpayers

Do Lower Taxes Increase Government Revenue?

Politicians frequently assert that tax cuts would increase economic growth and productivity and even pay for themselves by increasing long-term earnings. These declarations could appeal to voters who favor tax-cut declarations. But do tax cuts spur economic expansion?

Do Tax Reductions Spur Economic Expansion?

Tax reductions financed by borrowing from the private sector might very easily “crowd out” the extra discretionary income consumers have if the economy is near to full employment and the saving rate is low. As a result, the impact on growth is minimal, while the inflation rate will increase.

The notion that consumers could decide to save more money in response to tax cuts is another problem. The reasonable consumer may believe that a tax decrease supported by borrowing will result in increased taxes in the future. As a result, customers store their tax refunds instead of using them to buy goods and services.

How are tax reductions paid for?

Will a tax cut boost overall demand? In the beginning, it depends on how the tax decrease is paid for.

Spending Cuts

Imagine if the government reduced income taxes by $4 billion while also reducing welfare spending by $4 billion. In other words, expenditure reductions in the government are used to pay for the tax decrease. 

In this instance, an increase won’t occur since some individuals will benefit more from the tax cut while others would reduce their spending because of the decreased welfare benefits. The cyclical flow of revenue is not being injected into more often overall.

Government borrowing

The government might pay for the tax decrease by raising its debt ceiling. We are more likely to experience crowding out if the government boosts borrowing during a boom to support a tax cut. In essence, this means that the government will increase borrowing by issuing bonds to the private sector. 

The private sector will have less money to invest elsewhere if it purchases government bonds. Additionally, during periods of rapid expansion, increased borrowing may result in higher bond yields, and these higher interest rates push money out of the market.

Tax Reductions Paid For by Increased Production

Tax reductions may be possible if the economy experiences an increase in production. For instance, if an economy saw productivity growth of 4% annually (for instance, as a result of new technology), this rapid pace of economic growth would inevitably result in larger tax receipts (higher VAT, corporation tax). 

With this level of economic expansion, tax rates may be lowered while still generating the same amount of income.

Reduced Income Tax Rates’ Implications

The economy is impacted by income tax rate reductions in three key ways.

A Rise in Spending

The revenue available for workers’ choice will rise. Since they would keep a larger portion of their gross income with reduced income tax rates, they would essentially have more money to spend.

Increased Economic Growth

We may anticipate a surge in consumer expenditure with reduced tax rates since employees will likely be better paid. A rise in consumer expenditure should increase aggregate demand (AD), which should boost economic development because consumer spending makes up around 60% of AD.

Borrowing by the Government

Tax reductions will result in less tax collection, which is likely to result in increased borrowing. Although other economists contend that lowering income taxes will boost productivity, offsetting this revenue decline.

The Laffer Curve

The American economist Arthur Laffer developed the Laffer Curve, a bell-curve analysis that illustrates how variations in the tax rate on the government have an impact on revenue receipts. It implies that taxes may be either too low or too high to earn the most money, with both a 0% and a 100% income tax rate producing nothing in revenues. 

According to Arthur Laffer, tax reductions have both mathematical and economic implications on the government budget.


Every dollar in tax reductions immediately corresponds to one dollar less in government income, as well as a dollar less in the stimulative impact of government expenditure. This mathematical effect is immediate.


The impact on the economy is longer-lasting and multiplicative. Taxpayers will spend more of their increased income as a result of a tax decrease. Demand growth prompts greater company activity, which in turn boosts output and employment.

The Effects Of Lower Taxes

Lower income tax rates increase consumers’ purchasing power, which increases aggregate demand and supports economic growth (and possibly inflation). Income tax reductions may enhance labor incentives on the supply side, resulting in increased productivity. 

However, the impact of tax cuts relies on how they are paid for, how the economy is doing, and whether or not low tax rates genuinely boost productivity and work ethic.
