Stealth taxes are sometimes built into the prices of products so that consumers do not see how much tax they are paying.  

• In comparison to income taxes and property taxes, stealth taxes are smaller and less visible.  

• Because of their lower visibility they attract significantly less attention than income or property taxes.  
• Governments find stealth taxes easier to collect than other types of taxes because the government collects them at the point of sale and they do not depend on a taxpayer’s income level.  
• The most common stealth tax is the sales tax.
