Goods and Services Tax (GST) filing is a regular obligation for registered businesses. Whether you file monthly, quarterly or annually depends on your turnover and your country's rules. Accurate GST filing requires meticulous bookkeeping throughout the period - every transaction must have the correct GST treatment applied. Getting this right means you pay the correct amount and avoid penalties from your tax authority.

Standard rates vary by country: Australia 10%, New Zealand 15%, Singapore 9%, Canada 5% GST (plus provincial HST/PST), India has multiple rates (5%, 12%, 18%, 28%). SortBooks automatically applies the correct rate for your jurisdiction.
