Here are a few options for a WordPress `post_tag` description for “e-繳稅” (e-payment of taxes) in Traditional Chinese, with varying levels of detail:

**Option 1: Concise and Direct**

* **Description (建議):** 線上繳稅，方便快捷。 (Online tax payment, convenient and fast.)

**Option 2: Slightly More Explanatory**

* **Description (建議):** 透過網路進行稅款支付，省時省力。 (Paying taxes through the internet, saving time and effort.)

**Option 3: Focus on Benefit and Accessibility**

* **Description (建議):** 輕鬆、安全的電子繳稅方式。在家或辦公室即可完成稅務申報。 (Easy and secure electronic tax payment methods. Tax filing can be completed at home or in the office.)

**Option 4: Includes a Wider Context**

* **Description (建議):** 各種線上繳稅管道與資訊，包括所得稅、房屋稅等。 (Various online tax payment channels and information, including income tax, property tax, etc.)

**Recommendation:**

I recommend **Option 2** or **Option 3**. They are clear, concise, and effectively communicate the purpose of the tag. Option 2 is a bit more straightforward. Option 3 highlights the benefits. Choose the one that best suits the content of your posts.

**Important Considerations:**

* **Consistency:** Make sure the description aligns with the content of the posts you’ll be tagging with “e-繳稅.”
* **SEO:** While the primary function of the description is for internal organization, consider keyword usage within your description to potentially improve the SEO of your tag archive pages. If the post focuses on specific types of taxes (e.g., income tax, land tax), you could incorporate those keywords, e.g.: “線上繳稅資訊，包括所得稅、地價稅等。” (Online tax payment information, including income tax, land tax, etc.)
* **Character Limit:** WordPress doesn’t usually have a strict character limit for tag descriptions, but shorter is generally better for readability and potential display on your archive pages. Aim for a description that’s concise and informative within a few lines.
