Here are a few options for a WordPress post_tag description, keeping in mind clarity and brevity, and aimed at different levels of detail:

**Option 1: Concise and General (Best for most situations)**

> 關於薪資稅的相關資訊與討論。包括稅務計算、繳納方式、以及常見問題解答。 (About information and discussions related to salary tax. Includes tax calculation, payment methods, and answers to frequently asked questions.)

**Option 2: Slightly More Informative**

> 探索薪資稅的世界，了解您應繳納的稅款，以及如何遵守稅務法規。包含薪資稅的定義、稅率、申報程序等。 (Explore the world of salary tax. Learn what taxes you owe and how to comply with tax regulations. Includes the definition, tax rates, declaration procedures, etc. of salary tax.)

**Option 3: Focus on Practical Aspects**

> 薪資稅務實用指南。提供薪資稅計算方式、繳稅期限、以及減免的可能性。幫助您更好地管理您的稅務義務。 (Practical guide to salary tax. Provides methods for calculating salary tax, payment deadlines, and the possibility of deductions. Helps you better manage your tax obligations.)

**Option 4: If you’re targeting a specific audience (e.g., Taiwanese)**

> 台灣薪資稅資訊與分析。 涵蓋台灣個人所得稅中的薪資所得，提供稅務法規、申報流程、以及稅務規劃的最新資訊。 (Taiwan salary tax information and analysis. Covers salary income within Taiwan’s personal income tax, providing the latest information on tax regulations, declaration procedures, and tax planning.) (This option is only applicable if your content focuses on Taiwan.)

**Which one to choose?**

* **Option 1** is generally the best starting point for most use cases. It’s short, clear, and applicable to a wide range of content.
* Choose **Option 2** or **3** if you want to provide a slightly more comprehensive overview.
* Use **Option 4** if your content is specifically about Taiwanese salary tax.

**Important Considerations:**

* **Target Audience:** Consider who you are writing *to*. Are they novices or experts? Adapt the description accordingly.
* **Content of the Posts:** Make sure the description accurately reflects what the post actually *covers*. The description should act as a helpful summary.
* **SEO (Search Engine Optimization):** While descriptions aren’t the primary SEO factor, keywords like “薪資稅” (salary tax), “稅務” (taxation), “計算” (calculation), “申報” (declaration), “繳納” (payment) can be indirectly beneficial. Avoid keyword stuffing. The natural language is more important.
* **Limited Space:** Keep the description relatively short. WordPress might truncate longer descriptions. Aim for a concise and informative summary.

**To Add the description in WordPress:**
In most WordPress themes, you can edit the individual tag (post_tag) in the `Tags` section of your post editor (typically under `Posts` then `Tags`). You will find fields to fill in both the name (`薪資稅`, in this case) and the description. If you can’t find the description field, it might be hidden. Check your screen options (usually located at the top right of the edit screen) to ensure the “Description” box is checked.
