Input cells for schedule306
CellTypesRequired
businessNumberFiling corporation CRA business number, as a nine-digit root or full 15-character program account, used to match corporation-specific allocations such as Schedule 23. Other root-level aliases and the jacket or GIFI schedule identities may supply it when omitted. Missing, malformed or conflicting roots prevent an allocation match.null | string
corporationNameFiling corporation name used for Schedule 511 and other filing headers when the jacket name is blank. Send the legal name. If neither source supplies a name, this reader returns no name and the consuming form applies its identity checks.null | string
daysInYearinteger
filerBnFiling corporation CRA business number, as a nine-digit root or full 15-character program account, used to match corporation-specific allocations such as Schedule 23. Other root-level aliases and the jacket or GIFI schedule identities may supply it when omitted. Missing, malformed or conflicting roots prevent an allocation match.null | string

schedule101.insuranceUnderwritingTypeThe insurance underwriting subtype, read with isInsuranceCorp to decide whether the RC4088 Rev.23 p.5 PDF financial statement supplement advisory fires. Send it whenever isInsuranceCorp is true, using non_underwriting for brokerages, MGAs, agency subsidiaries and non-underwriting holding companies. No enum is published because the engine routes every unrecognized string to the ordinary-filer branch rather than rejecting it.null | string

schedule38Schedule 38 Part VI Tax on Capital of Financial Institutions input object. Its capital and institution facts support the federal calculation, T2 line 720 and provincial financial-institution capital-tax inputs. Omission supplies no Schedule 38 prepass or fallback identity facts; applicable return triggers still require the relevant facts.null | object
schedule38.partVI2TaxPayableForYearS67Optional practitioner cross-check of the Schedule 67 T2 line 725 Part VI.2 instalment deductible under ITA s.190.1(3)(a). It is never authority: batch computation supplies the server-produced Schedule 67 t2_line_725_feed, and a missing or conflicting feed blocks the deduction.null | number | string
schedule38.unusedSurtaxCreditsClaimedFromS42Optional cross-check of the unused surtax credit claimed on Schedule 42 under ITA s.190.1(3)(b). It is an internal component of amount 7B and appears on no printed CRA box. The value is never authority: a positive amount reduces Part VI only when the server-authenticated Schedule 42 opening register, source-year evidence, seven-taxation-year window and s.190.1(6) review support the same claim.null | number | string
