Dictionary

What each number means.

The data dictionary that ships with the dataset: each indicator's unit, description and source reference. Large breakdown tables (districts, countries, stations) are documented once as a grouped entry, by design.

  • Total TINs with Tax-Type Registration Activity

    Taxpayer Registration Detail · count

    Count of distinct TINs with at least one tax-type add/registration event in the period (Source A: Registration head).

  • Total Tax-Type Registrations (by Registration Date)

    Taxpayer Registration Detail · count

    Total tax-type registration events by registration date (Source A). NOTE: numerically identical to the cancellation series below and to the overall TIN-activity total in the raw export — a source-system data-quality artefact, retained as provided (verified by direct row-level comparison).

  • Total Tax-Type Cancellations (by Cancellation Date)

    Taxpayer Registration Detail · count

    Total tax-type cancellation events by cancellation date (Source A). See note above re: identical values to registrations.

  • Tax-Type Registrations by Status Code (Registered only, incl. Total)

    Taxpayer Registration Detail · count

    Status-code breakdown of tax-type registration records; 100% of records in the source export carry status REGD (Registered) — no other status values present.

    Source: Outputs_27072026.xlsx / Registration head (URA Taxpayer Register - tax-type level export, extracted 27 Jul 2026)

  • Tax-Type Registrations by Tax Type (13 tax types incl. Total)

    Taxpayer Registration Detail · count

    Tax-type registration counts broken down by tax type (e.g. VAT, PAYE, Income Tax, Rental Tax).

  • Tax-Type Cancellations by Tax Type (13 tax types incl. Total)

    Taxpayer Registration Detail · count

    Tax-type cancellation counts broken down by tax type. Verified row-for-row identical to the registration series above (data-quality artefact of the source export, not a labelling error on our part).

    Source: Outputs_27072026.xlsx / Registration head (URA Taxpayer Register - tax-type level export, extracted 27 Jul 2026)

  • Cumulative Tax Types Held, by Tax Type (13 tax types incl. Total)

    Taxpayer Registration Detail · count

    Sum of the number of active tax types held by TINs, broken down by tax type.

  • Total New TIN Registrations

    Taxpayer Registration Detail · count

    Count of new Tax Identification Numbers (TINs) issued (Source B: Registration output). Verified identical across four differently-dated pivot fields in the raw export (registration date, cancellation date, business-start date, TIN-issue date); the three redundant series were consolidated into this single row.

    Source: Outputs_27072026.xlsx / Registration output (URA Taxpayer Register - TIN level export, extracted 27 Jul 2026)

  • New TIN Registrations by Status (Cancelled / Merged / Registered, incl. Total)

    Taxpayer Registration Detail · count

    New TIN registrations broken down by current status code.

    Source: Outputs_27072026.xlsx / Registration output (URA Taxpayer Register - TIN level export, extracted 27 Jul 2026)

  • New TIN Registrations by Economic Sector — ISIC, Descriptive Labels (21 sectors + 1 unclassified, incl. Total)

    Taxpayer Registration Detail · count

    New TIN registrations by ISIC economic sector, descriptive labels (e.g. "A-Agriculture, forestry and fishing"). The source export also contains a second, single-letter-code sector field with different per-sector counts (same grand total) — see the next entry. Both are retained; the reason for the discrepancy is not documented in the source export.

  • New TIN Registrations by Economic Sector — ISIC, Single-Letter Code (21 sectors + 1 unclassified, incl. Total) [ALTERNATE SOURCE FIELD]

    Taxpayer Registration Detail · count

    A second ISIC sector breakdown present in the raw pivot export, using single-letter codes (A, B, C...). Grand total matches the descriptive-label version above (861,483) but individual sector counts differ (e.g. sector "A": 24,457 vs 22,652) — most likely two different underlying date/classification fields in the source system. Retained for completeness rather than discarded as originally (incorrectly) assumed to be a duplicate; flagged for URA clarification.

  • New TIN Registrations by Taxpayer Category (Individual / Non-Individual, incl. Total)

    Taxpayer Registration Detail · count

    New TIN registrations for foreign-linked taxpayers, broken down by 3-4 letter country code as recorded in the source system. Codes not expanded to full country names in this release; one dictionary entry covers all category rows.

  • New TIN Registrations by Filing/Obligation Flag (Yes / No, incl. Total)

    Taxpayer Registration Detail · count

    New TIN registrations by recorded filing/obligation flag.

    Source: Outputs_27072026.xlsx / Registration output (URA Taxpayer Register - TIN level export, extracted 27 Jul 2026)

  • New TIN Registrations by Gender, as Recorded (2 codes + 1 unclassified, incl. Total)

    Taxpayer Registration Detail · count

    New TIN registrations by a two-value source-system code (F / M). Interpreted as Female/Male based on the category labels and a plausible ~2:1 M:F distribution consistent with individual-taxpayer gender splits; this interpretation is not independently confirmed against a URA code list and should be verified before use in gender-disaggregated analysis. (Originally mislabelled in an earlier draft as an "unresolved channel/type code" — corrected.)
