Why this schema exists

GOV-960's per-country x per-vertical audit found 7 of this registry's 11 jurisdictions (AU, SG, CA, IE, NZ, IN, NL) had a Drivers-Licence schema but no Vehicle Registration/Tag/Title schema in the DMV vertical. GOV-968 closed one leg of IE's gap with ie/revenue/vehicle-registration-tax-vrt — but VRT is a one-time import/first-registration tax, not the recurring annual/periodic motor tax every Irish vehicle must carry to be used on a public road. This GOV-993 research cycle's own audit confirmed IE still had no schema for that recurring renewal (the direct counterpart to gb/dvla/vehicle-tax, de/kba/vehicle-registration's renewal leg, au/nsw/service-nsw/vehicle-registration-renewal, and us/*/dmv/vehicle-registration-renewal), and picked Motor Tax Online (motortax.ie) as the next candidate: it is Ireland's single national online channel for this process (unlike driving-licence renewal's NDLS-run system), with live, unauthenticated guidance pages describing exactly what the online service needs.

Sources examined

• Document (id, version): ie/dttas/motor-tax-renewal / 1.0.0
• Spec version: GovSchema 0.3.0
• Authority: Department of Transport, whose Driver and Vehicle Computer Services Division (DVCSD) maintains the National Vehicle and Driver File; motor tax is collected by local authorities' motor tax offices, jointly operating Motor Tax Online with the Department (see authority.operatedBy, GSP-0020).
• Primary source: the live motortax.ie login page (https://www.motortax.ie/OMT/omt.do), fetched directly as raw HTML via curl with a standard desktop user agent, 2026-07-04. No bot-block was encountered (HTTP 200, full page content, including the "What do I need to tax my vehicle online?" and "What types of vehicle can be taxed online?" sections used as the field-level source below).
• Secondary source: the Department of Transport's gov.ie publication "Motortax: Payments, Renewals and Refund information" (https://www.gov.ie/en/department-of-transport/publications/motortax-payments-renewals-and-refund-information/), fetched directly as raw HTML, 2026-07-04 (HTTP 200; a prior WebFetch attempt at the same URL returned a tool-level 403, but a direct curl with a desktop user agent succeeded — the page itself is not authenticated or bot-blocked). This is the most detailed public description of the renewal process, including the tax-period rules, the commercial-vehicle roadworthiness/RF111A prerequisites, and the online "what you need" list.
• Tertiary source: citizensinformation.ie's motor tax coverage, found via web search (the page itself returned HTTP 403 to direct WebFetch; only the search-result summary was used, and only for values also independently confirmed in the two primary/secondary sources above).
• Live login attempt: a fabricated registration number (12D34567) and PIN (123456) were submitted to motortax.ie/OMT/login.do (with the page's CSRF token and session cookie). The service returned "Details Incorrect (please see below) — The combination of registration number and PIN entered was not valid" — a real server-side lookup against DVCSD's vehicle/PIN records, not a generic client-side format-validation error. This is the same class of gate already documented for ca/on/mto/vehicle-permit-renewal and au/nsw/service-nsw/vehicle-registration-renewal: no screen beyond login (vehicle confirmation, tax-period selection, payment) could be reached without an already-issued, real Irish vehicle registration and PIN.
• Form investigated and excluded: RF111 (the downloadable "Change of Particulars" form, fetched and text-extracted via pdfjs-dist) was initially considered as a possible field-level source, since it is the only motor-tax PDF form readily downloadable from motortax.ie. On review it is a different service — notifying a change of name/address, vehicle colour, body type, or tax class — not an application to renew tax, and none of its fields were used here.

Honesty flags (deliberate, recorded rather than glossed over)

• No screen beyond login was independently reached. As with the Ontario and NSW vehicle-registration precedents, the live transaction is gated behind a real registration-number/PIN pair. The tax-class list, tax-period rules, commercial-vehicle prerequisites, and "what you need" list are transcribed from the login page and the Department of Transport's guidance publication, not independently screen-captured past login.
• Whether Motor Tax Online still asks for insurance details is disputed between sources. A third-party blog surfaced during web search claimed insurance details are "no longer" required online; the Department of Transport's own gov.ie publication (last updated 2025-04-12, more authoritative and more recently updated than the blog) explicitly lists insurer name, policy number, and expiry date under "What do I need to tax my vehicle online?" This schema follows the gov.ie source and models insurance as required; a future review should re-check this directly against a live, authenticated OMT session if access becomes available.
• paymentCardType's enum (Visa/MasterCard only) is a direct quote, not an inference — unlike au/nsw/service-nsw/vehicle-registration-renewal's analogous field, both sources here name the accepted card brands explicitly. Card number, expiry, and CVV are out of scope by design (PCI DSS data, not a GovSchema field-collection concern).
• Scope excludes first-time taxing (RF100/dealer-mediated), change of particulars (RF111), off-road declaration (RF150), refunds (RF120), and replacement documents (RF134) — each a distinct motor-tax service named in the gov.ie publication but out of scope for a renewal-only schema.

Worked example (mock data, not a live submission)

Scenario: an individual renewing a standard private car's motor tax online for 12 months, with a current insurance policy and no commercial (goods) vehicle requirements.

| Field | Mock value | |---|---| | vehicleTaxClass | private_car | | vehicleRegistrationNumber | 12D34567 | | pin | 123456 | | isLightGoodsVehicle | (not asked — vehicleTaxClass is not goods_vehicle) | | lightGoodsDeclarationSubmitted | (not asked) | | roadworthinessCertificateHeld | (not asked) | | taxPeriodMonths | 12 | | contactEmailAddress | aoife.murphy@example.ie | | insuranceCompanyName | Example Insurance Ireland DAC | | insurancePolicyNumber | EI-2026-0456789 | | insurancePolicyExpiryDate | 2027-06-30 | | paymentCardType | visa |

Walking this data through the modelled steps[]: vehicle_tax_class's transition does not fire (vehicleTaxClass is not other_not_listed), so the flow proceeds to log_in → commercial_vehicle_checks (all three fields correctly left unset, since vehicleTaxClass is not goods_vehicle) → tax_period → contact_and_insurance → payment, the final step. This is a self-consistency check of the schema's own branching and conditional- requirement logic, not a substitute for a live renewal transaction — see the honesty flags above. See conformance/ie/dttas/motor-tax-renewal/1.0.0/ for the machine-readable rendering of this same walkthrough.

Path to verified

1. Obtain a real (or realistically complete) Irish vehicle registration number and current PIN to walk the live motortax.ie transaction past login and confirm the vehicle-confirmation, tax-period, and payment screens field-by-field.
2. Independently re-confirm whether the online flow still collects insurance details, resolving the disputed-source flag above directly against a live, authenticated session.
3. Consider companion schemas for first-time taxing (RF100), change of particulars (RF111), the off-road declaration (RF150), and refunds (RF120), each explicitly out of scope here.

Re-verification

Per the practice's Cadence, nextReviewBy is set to 2027-01-01 (6 months). Re-check the source on or before that date and on any source.url change.
