What Happens If You Miss the Deadline
- USA: 0.5% of unpaid tax per month (up to 25%) plus interest; late-filing penalty 5% per month (max 25%).
- UK: GBP 100 automatic penalty, then daily penalties after 3 months; 5% of tax due at 6 and 12 months.
- Germany: late-filing surcharge 0.25% of assessed tax per month (min EUR 25).
- Australia: failure-to-lodge penalty from AUD 313, scaling with repeated offences.
- India: late fee INR 5,000 + 1% interest per month on unpaid tax.
- Most other countries: interest plus fixed or percentage penalties — and 2026 is a bad year to be late, because DAC8, CARF and 1099-DA give authorities your data whether you file or not.
