FAQs on Income Tax Calendar
- Where can I find the latest tax calendar for India?
The Income Tax Department updates the official calendar each year. You can find it on incometaxindia.gov.in or on popular tax platforms like Bankbazaar, and the GST portal for GST-specific deadlines.
- What happens if I miss a tax deadline?
Missing a deadline can lead to fines or interest charges. For example, a late ITR filing can cost up to Rs.5,000 under Section 234F, and you might also lose the chance to carry forward losses.
- What are some important tax dates I should remember in India?
Some key ones include:
- 31st July: Last date to file ITR (for most individuals)
- 15th June/Sept/Dec/March: Advance tax installments
- 31st March: Deadline for belated or revised ITR of the previous year
These dates can change, so it’s always good to double-check with the official portals.
- Are tax deadlines the same every year in India?
Not always. While some dates like ITR filing or advance tax payments usually fall around the same time each year, they can shift due to government announcements, budget updates, or unforeseen situations.
- Is there a difference between individual and business tax calendars?
Yes, businesses often have more frequent and varied tax deadlines compared to individuals. In addition to ITR filing, they also have to deal with TDS/TCS returns, GST filings, and audit report submissions. The tax calendar for businesses is more detailed and needs closer tracking.
