Penalty calculation rules by country
Australia
Australia has a fixed base penalty of $222 for late filing plus 5% of the GST amount. Late payment penalties are 2% of the GST amount but only apply after 28 days.
Late Filing = $222 + (GST × 5%) Late Payment = GST × 2% (if > 28 days)
Example: GST: $10,000 → Filing: $222 + $500 = $722
India
India charges $100 per day for late filing, capped at $5,000. Late payment penalties are 10% of the GST amount.
Late Filing = min($100 × Days, $5,000) Late Payment = GST × 10%
Example: GST: ₹50,000, 30 days → Filing: ₹3,000
New Zealand
New Zealand has a tiered penalty structure. Base penalty is $50, plus $250 after 7 days, plus 1% of GST after 30 days.
Late Filing = $50 + $250 (if > 7 days) + GST × 1% (if > 30 days)
Example: GST: NZ$20,000, 35 days → NZ$500
Common Questions
Answers to frequently asked questions about GST late fees.
Late filing penalty applies when you don't submit your GST return on time. Late payment penalty applies when you don't pay the GST owed by the due date. You can be penalized for one or both. For example, if you file on time but pay late, you only get a late payment penalty.
Yes, in most countries you pay both. The penalty is a one-time charge for non-compliance. Interest accumulates daily on the unpaid amount. Use both calculators to get the total cost. For example, 30 days late might incur $722 in penalties plus $82 in interest.
Some tax authorities may waive penalties for first-time offenders or if you have a reasonable excuse. Contact your tax authority to request a waiver, but don't assume it will be granted. You typically need to demonstrate reasonable cause for the delay.
File and pay on time. Set reminders before due dates. If you can't pay in full, file on time anyway and arrange a payment plan to minimize penalties. Many tax authorities offer payment plans that reduce or eliminate penalties.
We update rates regularly, but tax laws change. Always verify current penalty rates with your country's official tax authority website before making decisions. Penalty structures can change annually or when tax laws are updated.
