pub struct TaxPostingGenerator;

Generates GL journal entries for tax postings derived from TaxLine records.

Implementations

impl TaxPostingGenerator

pub fn generate_tax_posting_jes( tax_lines: &[TaxLine], company_code: &str, doc_dates: &HashMap<String, NaiveDate>, fallback_date: NaiveDate, ) -> Vec<JournalEntry>

Generate GL journal entries for each eligible TaxLine.

Rules

Document type	Deductible	Action
CustomerInvoice	any	DR AR Control / CR VAT Payable
VendorInvoice	true	DR Input VAT / CR AP Control
VendorInvoice	false	Skipped – tax absorbed into expense
JournalEntry	any	Skipped
Payment	any	Skipped
PayrollRun	any	Skipped
Generate GL journal entries for each eligible TaxLine.

Each JE is dated using the source document’s date from doc_dates (keyed by TaxLine::document_id), falling back to fallback_date when no mapping is found. This prevents all tax JEs from clustering at period-end when a single blanket posting date was previously used.
