I'm sorry, but as an HR professional, I don't have real-time data or the ability to provide past or future tax rates for specific regions like Gujarat. However, the professional tax slab rates in Gujarat, like in all parts of India, are subject to change and are determined by the state government.
Here's the general process you can follow to find this information:
- Step 1: Visit the official Gujarat government website or the Gujarat commercial tax department's website.
- Step 2: Look for the 'Professional Tax' section.
- Step 3: Check for historical data or archives for the professional tax slabs for the years you're interested in.
- Step 4: If you can't find the information online, consider reaching out to the office directly.
Also, please consult a tax professional or a tax consultant to get the most accurate and legally sound advice on this matter.
