GST Interest Calculator (Section 50, 18% per annum)
Full analysis: we compute your tax + interest + penalty exposure, the limitation / time-bar position, and whether the issuing officer had the monetary authority to raise this demand — every figure deterministic and source-cited.
About this tool
Estimate the section-50 interest accruing on an unpaid GST demand. Our engine computes interest deterministically to the as-of date as part of the full exposure on any DRC notice you upload.
How it works
- Upload your DRC notice to get interest computed on the actual demand and periods.
- Interest = tax × 18% × days / 365, projected to today (never a fixed notice figure).
