Use Tax Summary to summarize tax results

Determination summarizes tax results at the line level in the XML output and stores the data in the audit schema of your database. Line-level summaries are useful in some ERP integrations (such as Oracle and SAP), reports, and returns processing.
The line-level summary includes the following:
  • The taxable basis and exempt amount in the tax block, as well as the non-taxable amount.
  • Data such as the maximum taxable basis, exempt amount, total tax rate, effective tax rate, and other data.
  • Where currency applies, it's the currency of the document.

Tax Summary XML elements

A brief explanation of tax summary XML elements follows.
  • The taxable basis gets set at the tax line level. If the authority's fully exempt, the taxable basis is zero.
    • Taxable basis contains the maximum taxable basis from the amount of the authority tax lines.
    • If an authority tax line's a tier, then all tiers for that authority have their taxable basis summed and treated as a single tax line for the purpose of determining the maximum taxable basis.
    • If the total exceeds the gross amount, the taxable basis gets set at the gross amount.
  • The non-taxable basis contains the maximum non-taxable basis from the tax results, including tiered results. If the non-taxable basis percent's less than 100%, this element is calculated as (1 - basis percent) * gross amount.
  • The exempt amount's set at the tax line level; if the authority's flagged as fully exempt from the rule or there is an exempt certificate, this tag shows the basis for the exemption.
  • The tax rate's the sum of all tax rates; no special treatment is applied for rates from tiers. If all taxes are fees, the value of this element's zero.
  • The effective tax rate's the total taxes on the line divided by the maximum taxable basis.
  • The advisories contain elements for allocations, custom authorities, fees, tiers, and variable exempt amounts.
Advisories notify you of special summary conditions that may produce unexpected results. You may get a different effective or total tax rate than you expected if you have allocates or tiers because various authorities get taxed at different percentages or amounts.
