OMV / ARF / PARF (Singapore): What they mean, why they matter

These terms sit inside Singapore's vehicle tax and deregistration framework—so they can change the net cost of ownership. If you compare auto financing offers without aligning OMV/ARF/PARF assumptions, "cheaper" can be an illusion.

One-line definitions

OMV: Open Market Value — a value used in Singapore's vehicle tax framework; it is an input used in calculating certain taxes.

ARF: Additional Registration Fee — a registration-related tax component that can be calculated based on OMV, affecting upfront cost.

PARF rebate: A deregistration rebate under Singapore's scheme that can depend on ARF and vehicle age/conditions, changing net ownership cost.

If you're comparing offers, pair this page with Terms & Calc so you compare on net cost, not just instalments.

Why it matters for auto financing comparisons

These affect net ownership cost: taxes and rebates can shift what you "really pay" over the ownership horizon.
Used vs new comparisons: rebates and tax components can differ materially across vehicle types and age.
Fair comparison requires aligned assumptions: if one quote assumes a rebate scenario and another doesn't, the "best rate" conclusion becomes unreliable.

Practical capture fields for comparisons: OMV (as shown), ARF amount, whether PARF rebate applies, and the assumed deregistration timing.

How OMV / ARF / PARF generally connect (high-level)

Think "value → tax → rebate"

OMV is a value used in the tax basis.
ARF is a registration fee/tax component that may be computed from OMV under the rules.
PARF rebate can be tied to ARF and eligibility conditions, affecting net cost on deregistration.

Where people get misled

Focusing on monthly instalment while ignoring rebate eligibility.
Assuming rebate amounts are "guaranteed" without checking conditions.
Comparing two vehicles without aligning the same ownership horizon.

What to do next

Use Terms & Calc to compare total paid and effective cost.
Use COE & PQP to align major cost drivers.
Use Tools to compute comparable scenarios.

Common misconceptions

"OMV is the showroom price." → OMV is a value used within the tax framework; don't treat it as the retail price.
"ARF is just admin." → ARF is a major cost component tied to the tax framework and can be material.
"PARF rebate always applies." → Eligibility and amount depend on conditions; confirm the relevant scheme and timing.

FAQ

Does OMV/ARF/PARF affect my interest rate?

These mainly affect cost basis and net ownership cost. Your interest rate depends on lender terms, but what you finance can change if overall price changes.

Why do rebates matter when I'm just looking at monthly instalments?

Because rebates can change net cost. Two offers with similar instalments can have different net ownership costs if one scenario includes different rebate assumptions.
