          Frequently Asked Questions

          What if I miss the deadline?

          Late filing incurs penalties and interest charges. Professional help can minimise these penalties.

          Do I still need to file if I made a loss?

          Yes, you must still file. A rental loss can be carried forward to offset future profits—but only if properly declared.

          Can I amend previous returns?

          Yes, returns can be amended up to four years back. If you've missed deductions, we can help claim them.
