Here are a few options for a WordPress post_tag description for “繼承稅” (Inheritance Tax) in Traditional Chinese, ranging in detail:

**Option 1: Concise and Direct**

* **Description:** 處理遺產時可能需要繳納的稅項。
* **Translation:** Taxes that may need to be paid when handling an inheritance.
* **Why it works:** Simple, gets straight to the point, and is suitable if you use a related tag for different kinds of taxes.

**Option 2: Slightly More Informative**

* **Description:** 繼承財產時，根據相關法規需要繳納的稅款。了解繼承稅的計算方式和應注意事項。
* **Translation:** Taxes payable when inheriting property, according to relevant laws and regulations. Learn about the calculation methods of inheritance tax and things to pay attention to.
* **Why it works:** Provides a bit more context, mentioning calculation methods, and implies that your post content will offer useful information.

**Option 3: Emphasizing the Scope**

* **Description:** 關於繼承稅、遺產稅、以及相關稅務法規的資訊。包括稅額計算、申報流程、免稅額度，以及如何規劃繼承事宜。
* **Translation:** Information about inheritance tax, estate tax, and related tax regulations. Including tax calculation, declaration procedures, exemptions, and how to plan inheritance matters.
* **Why it works:** Offers a broader scope, touching on different aspects of inheritance tax and its implications, suggesting helpful content on your blog.

**Option 4: Using Specificity (if applicable to your content)**

* **Description:** [Country/Region] 繼承稅指南：介紹針對 [Region] 繼承稅的相關規定、最新的稅率，以及如何合法避稅。
* **Translation:** [Country/Region] Inheritance Tax Guide: Introduces the regulations regarding inheritance tax for [Region], the latest tax rates, and how to legally avoid taxes.
* **Why it works:** This should be used *only if* your content is exclusively for a specific geographic area (e.g., Taiwan, Hong Kong). Be sure to replace `[Country/Region]` and `[Region]` appropriately.

**How to Choose:**

* **Consider your content:** Does your post cover just the basics or a more in-depth analysis?
* **Your target audience:** What level of detail do they expect?
* **Other tags:** How does this tag relate to your other tags?

I recommend starting with Option 2 or 3, as they provide a good balance of information and relevance. Customize Option 4, being mindful of your target audience’s region.
