Chart of Accounts
Mapping Tool

Paste or upload a trial balance. Auto-map every account to your reporting framework. Override, review, export.

A chart of accounts mapping assigns each trial balance account to a reporting category under IFRS (IAS 1.54), Dutch GAAP (RJ 260), HGB (§266/§275), or US GAAP. This tool auto-suggests mappings by account name keyword matching, lets you override each one via dropdown, and exports the result as a working paper or Excel file.

How chart of accounts mapping works

Every entity maintains its own chart of accounts (COA), structured to fit internal reporting needs. Auditors and finance teams must reclassify those codes into the presentation categories required by the applicable financial reporting framework before financial statements can be prepared or audited.

Under IFRS, IAS 1.54 and IAS 1.77 prescribe the minimum line items for the statement of financial position and profit or loss. Dutch GAAP follows RJ 260, while HGB §266 (balance sheet) and §275 (income statement) define the German statutory format. US GAAP follows SEC Regulation S-X presentation rules.

When to re-map

Re-mapping is required at the start of every audit engagement, when the client changes its chart of accounts mid-year, or when the entity transitions from one reporting framework to another (for example, Dutch GAAP to IFRS). The mapping also forms the basis for lead schedules and analytical review procedures.

What this tool does

This tool accepts a trial balance in CSV, Excel, or pasted format. It reads account codes, names, and balances, then auto-suggests a reporting category for each account using keyword matching. You can override any suggestion via dropdown. The grouped summary shows subtotals by reporting category, and the working paper export documents every mapping decision for the audit file.

Frequently asked questions

What is a chart of accounts mapping?
A chart of accounts mapping links each general ledger account in a trial balance to a standardised reporting category defined by a financial reporting framework (IFRS, Dutch GAAP, HGB, or US GAAP). This reclassification ensures the trial balance feeds correctly into the financial statements.
Why do auditors need to re-map trial balance accounts?
Client chart-of-accounts codes are entity-specific. To test financial statement line items, auditors need to aggregate those codes into the presentation categories required by the applicable framework (IAS 1.54 for IFRS, RJ 260 for Dutch GAAP, or HGB §266 for German entities). Without a mapping, individual account balances cannot be traced to the statements under audit.
Which reporting frameworks does this tool support?
The tool supports IFRS (IAS 1 presentation), Dutch GAAP (RJ), German GAAP (HGB), and US GAAP. Each framework uses its own set of reporting categories and group labels.
Can I upload an Excel file directly?
Yes. The tool accepts CSV, TSV, and Excel (.xlsx / .xls) files. It expects at least two columns: account code and account name. A third column for the balance is optional but recommended. The first row is treated as a header.
