Taxes like gift tax, wealth tax etc are also referred to as which type of taxes?

The correct answer is Paper taxes.

To understand why, let's break this down step by step.

Step 1: Understanding the Nature of Gift Tax and Wealth Tax
Taxes such as gift tax and wealth tax share a very specific characteristic — they are not collected through a regular, automated payroll or transaction process. Instead, they require the taxpayer to voluntarily declare their assets, gifts received, or wealth on a written form or return and submit it to the tax authority.

Step 2: What are "Paper Taxes"?
Paper taxes refer to taxes that are assessed and collected primarily on the basis of self-declaration through paper-based filings — meaning the taxpayer must fill out and submit physical or formal written returns/documents. These taxes rely heavily on the honesty and accuracy of what the individual reports on paper, rather than being automatically deducted at source.

Step 3: Why Not the Other Options?

• Paperless taxes — This is not a standard tax classification. It contradicts the paper-filing nature of gift and wealth taxes.
• Rich taxes — While wealth tax and gift tax do tend to apply more to wealthier individuals, "Rich taxes" is not a recognized or formal tax terminology.
• Direct taxes — Although gift tax and wealth tax are indeed a form of direct tax (paid directly by the individual to the government), the question asks specifically what they are "also referred to as," pointing to a more specific informal/category label, which is "Paper taxes."

Step 4: Conclusion
Taxes like gift tax, wealth tax, estate duty, etc., which depend on the individual declaring assets and transactions via formal written submissions (paper returns), are collectively referred to as Paper taxes. The term highlights how the tax liability is determined largely from what is declared and documented on paper by the taxpayer.
