California Partial Year Registration: PYR Rules & Fees

Last verified: September 4, 2026

Partial Year Registration (PYR) lets a California commercial motor vehicle register for one month or more but less than twelve, under Vehicle Code sections 9700 through 9711. Only the weight or CVRA portion prorates; registration, license and county fees stay due in full, plus $28 per period. Sticker Quicker, a licensed California DMV business partner (license OL 90656), handles registration and title filings for customers across California.

Every fleet manager with a seasonal truck has had the same thought: the thing runs four months a year, why am I paying twelve months of registration?

California has an answer, and it has had one since long before anyone reading this took over the yard. It is called Partial Year Registration. It is real, it works, and it saves genuine money on heavy equipment.

It also does about half of what most people assume it does. The word “partial” is doing a lot of lifting, and the part it does not cover is the part everyone budgets for. Here is the whole mechanism, verified against DMV’s own pages, forms and fee memos as of August 31, 2026.

What Partial Year Registration actually is

PYR is a registration status for commercial motor vehicles that are not operated throughout a calendar year. DMV describes the eligible population in one line:

“Commercial motor vehicles not operated throughout a calendar year may be eligible for partial year registration (PYR).”

You declare a period of use. You pay for that period. If you later need more months in the same calendar year, you notify DMV and pay again. The statutory home is Article 5 of Chapter 6, titled “Partial Year Payment of Weight Fees,” and that title is the single most useful clue in the entire program. It is a weight fee mechanism. It was never a registration discount.

Who qualifies

  • Commercial motor vehicles. This is a motor vehicle program.

  • Trailers do not qualify. All California trailers register under Permanent Trailer Identification (PTI), which has no annual renewal, so there is nothing to prorate. Park trailers and trailer coaches are the exception to PTI, and neither is a commercial motor vehicle.

  • Vehicles operating at a gross or combined gross weight of 10,001 pounds or more must register commercially in the first place, which is the population PYR is built around.

  • Lighter commercial vehicles are in scope too, on a different fee tier: pickups with an unladen weight of 8,000 pounds or less, and motor vehicles operating under 10,001 pounds.

The part nobody budgets for: what actually prorates

This is the whole article in one table. On your first PYR period, most of the bill is due in full regardless of how many months you buy.

Fee component Prorated? Notes
Registration fee No, due in full Paid in full on the first period of the calendar year
Vehicle License Fee (VLF) No, due in full Same
County and district fees No, due in full Same
CTIP (Commercial Vehicle Transportation Improvement), $3 No Not due at all for pickups, tow trucks, or vehicles used solely to transport people for hire
Unladen weight fee (light tier) Yes Prorated by month for pickups at 8,000 lbs or less unladen, and motor vehicles under 10,001 lbs operating weight
CVRA weight fee (heavy tier) Yes, mostly Prorated by month, but see the $122 exception below
The $122 CVRA motor vehicle fee No Rides on top of the prorated amount every time
PYR service fee, $28 No, and it repeats Charged once per declared period, not once per year
CVRA weight decal fee, $3 Situational Due again on a later period only if the operating weight changes

So a four-month PYR on a heavy truck is not a third of the annual bill. It is the full registration, VLF and county stack, plus roughly a third of the weight fee, plus $122, plus $28. Any fleet page promising “pay only four twelfths of your registration” is describing a program California does not operate.

That arithmetic is the decision point: make the trip yourself or hand the filing off. Sticker Quicker is a licensed California DMV business partner, license OL 90656, working on a real-time connection to the California DMV and returning completed documents, plates and stickers by next-day FedEx rather than a counter visit. Fleet accounts get a dedicated DMV account executive, and the Virtual Garage tracks fleet renewal deadlines, stores documents and alerts before a date passes. Statewide online, or walk in at the Fremont office.

The proration math, precisely

DMV divides the weight or CVRA portion by twelve and multiplies by the number of consecutive months in your declared period. In DMV’s own fee appendix, the January column shows the full-year weight fee plus $122; every column from February through December shows the prorated amount calculated after deducting the $122, which is then added back on. The $122 never shrinks.

For scale, the statutory CVRA weight schedule printed on form REG 4008 runs from Code A at 10,001 to 15,000 pounds at $332, through Code I at 50,001 to 54,999 pounds at $1,270, up to Code N at 75,001 to 80,000 pounds at $2,064. On a Code N tractor, four months of PYR saves roughly two thirds of a $2,064 line item. That is real money. It is just not two thirds of the whole bill.

The $28 service fee, and the timing that decides everything

The PYR service fee sits under Vehicle Code section 9702 and it moved on January 1, 2026. DMV’s Vehicle Industry News memo VIN 2025-10, issued December 3, 2025, raised fee code 456 from $27 to $28 as part of the annual CPI adjustment. The same memo moved several other fleet-relevant numbers effective the same date.

Fee (effective January 1, 2026) Was Now
PYR service fee, VC 9702, fee code 456 $27 $28
Registration fee, fee code 001 $71 $73
CHP fee $32 $34
CHP CVRA fee $54 $56
Planned Non-Operation service fee, VC 4604(b) $27 $28
Road Improvement Fee $118 $121

The service fee charges per declared period. Four separate one-month periods across a calendar year cost four service fees, not one. If your season is genuinely continuous, declare it as one block. If you split it because a truck sat idle for six weeks in the middle, you are buying a second $28 and a second round of paperwork to save six weeks of prorated weight fee. Run that math before you split.

The filing window

File on or before the vehicle’s annual registration expiration date. DMV accepts PYR fees, or a Planned Non-Operation filing, up to 60 days before that date:

“DMV will accept PYR fees or planned nonoperational (PNO) status filing fees up to 60 days prior to the vehicle registration expiration date.”

PYR is not an online transaction

This is the operational fact that costs fleets the most hours, and it is easy to miss because nearly everything else at DMV moved online. PYR is filed by mail or in person. DMV states that for the initial election and for every subsequent period of use. Questions route to Motor Carrier Services.

Two forms carry the work:

  • REG 4008, Declaration of Gross Vehicle Weight (GVW) / Combined Gross Vehicle Weight (CGW), REV. 5/2015. Required when the operating weight changes for a second or subsequent period.

  • REG 102, Certificate of Non-Operation / Planned Non-Operation Certification, REV. 10/2009. Required at renewal to certify the vehicle was not operated since the end of the most recently paid period.

PYR is a notification plus a fee payment, supported by those two forms.

PYR, PNO, PFR or full year: picking the right one

California gives a fleet four distinct answers to “this truck is not working right now,” and choosing wrong is expensive. Here is the whole decision.

Your situation The right filing Cost What it does
The truck works part of the year and drives on public roads during that part Partial Year Registration Full registration, VLF and county fees, plus prorated weight, plus $28 per period Legal operation for the declared months only
The truck will not touch a public road at all Planned Non-Operation (REG 102) $28 service fee Registration stays valid, full fees are not charged. Street parking breaks it
You run 50 or more commercial or passenger motor vehicles Permanent Fleet Registration $1 service fee per vehicle No individual renewal notices, a monthly expiration listing instead. Requires business name or logo legible at 50 feet on both sides
The truck works all year, or close to it Standard full-year registration Full fee stack Simplest. No period tracking, no repeat service fees

Two details in that table deserve more than a row.

First, PNO behaves differently for a PYR vehicle. DMV calls it open-ended: you have until December 31 of the following year, which DMV describes as “the end of the complete annual registration period for PYR vehicles.” Once the PNO is set, nothing further is required until you operate again. But the 90-day rule still bites. File more than 90 days after December 31 and, in DMV’s words, “eligibility for PNO status is forfeited and full year fees and penalties are due.”

Second, Permanent Fleet Registration has a lower door than most fleets realize. The threshold is 50 vehicles directly, but only 25 if you register through an authorized registration service agent or association that handles 250 or more vehicles. Motorcycles and trailers are not eligible, and the vehicles must carry your business name or logo on both sides, legible at 50 feet.

The trap that silently ends your PYR status

There is one sentence on DMV’s PYR page that has cost more fleets money than any other line in this program:

“Paying full registration, vehicle license, and unladen weight or CVRA fees at any point during the year changes your vehicle from PYR to full year registration status.”

Nobody does this on purpose. It happens when a renewal notice lands, an accounts payable clerk pays the number printed on it, and the vehicle quietly converts. Nothing bounces. Nothing warns you. You simply bought twelve months for a truck that works four, and if the payment landed after expiration you also bought penalties.

The defense is procedural, not clever: PYR vehicles need to be flagged in whatever system approves registration payments, so a full-fee invoice on one of them stops for review.

Operating outside your period, or above your declared weight

Once your declared period lapses, the vehicle is simply unregistered. The ordinary late-payment penalty ladder applies if you then pay full fees.

Weight is treated more harshly. REG 4008 prints the enforcement chain on the form itself: CVRA fees must be deposited with DMV before operating at the higher weight under Vehicle Code section 9406.1, citations issue under the same section, late fee penalties fall under 9554.2, and on conviction, fines under section 42030.1 reach “up to or in excess of $2,000 per violation.”

One relief and one non-relief. If your declared weight increases mid-period, additional CVRA fees are due on the higher range for the remainder of the PYR period, and you file a new REG 4008 and pay a new decal fee. If it decreases, DMV issues no refund.

Renewing a PYR vehicle next year

  1. Confirm the vehicle did not operate after your last paid period ended. This is the substance of the filing, not a formality.

  2. Complete REG 102 certifying non-operation since the end of the most recent paid period.

  3. Decide your first projected period of use for the new calendar year. Consecutive months only.

  4. Pay the full registration fee, VLF, and county and district fees, plus the prorated weight or CVRA fee, plus CTIP if applicable, plus the $28 service fee.

  5. Skip the weight declaration unless the operating weight changed. DMV states the operating weight for PYR vehicles does not have to be declared each renewal unless it changes.

  6. File by mail or in person, up to 60 days before the expiration date. Fees may be paid at any time during the year, as long as it is before you operate the vehicle.

One more piece of good news buried in the mechanics: your CVRA weight decal is issued once. Subsequent renewals issue year stickers only, unless the operating weight changes or you need a replacement.

Where Sticker Quicker fits

PYR is not hard. It is fiddly, it is offline, and it punishes inattention. Those are three different problems and they compound across a yard full of trucks.

A single seasonal dump truck is a manageable annual chore. Fifteen of them, each with its own declared period, its own expiration date, its own weight code and its own $28 service fee, is a tracking problem that lives in someone’s head until the day that person is on vacation. That is the failure mode: not a wrong form, a missed date.

Frequently asked questions

What is Partial Year Registration in California?

Partial Year Registration (PYR) is a California DMV status for commercial motor vehicles not operated throughout a calendar year. You declare a period of one month or more but less than twelve, and pay a prorated weight or CVRA fee for those months. It is governed by Vehicle Code sections 9700 through 9711.

Does PYR prorate my whole registration bill?

No. Only the unladen weight fee or CVRA weight fee prorates by month. The registration fee, Vehicle License Fee, county and district fees and CTIP are all due in full on the first period of the calendar year. The $122 CVRA motor vehicle fee is never prorated either.

How much is the California PYR service fee?

The PYR service fee under Vehicle Code section 9702 is $28, effective January 1, 2026, raised from $27 by DMV memo VIN 2025-10 issued December 3, 2025. It is charged once per declared period of use, so a vehicle registered for two separate periods in one calendar year pays it twice.

Can I file Partial Year Registration online?

No. DMV states that PYR is filed by mail or in person, both for the initial election and for every subsequent period of use. Questions are routed to DMV Motor Carrier Services. Any service claiming online PYR filing is describing something else.

What is the difference between PYR and PNO?

PYR registers a commercial vehicle for part of the year so it can legally operate during those months. PNO declares that the vehicle will not be driven, towed, stored or parked on any public road at all, which keeps the registration valid without full fees. Both currently carry a $28 service fee.

Can trailers use Partial Year Registration?

No. All California trailers register under Permanent Trailer Identification, which has no annual renewal and therefore nothing to prorate. Park trailers and trailer coaches are excluded from PTI but are not commercial motor vehicles. PYR applies to commercial motor vehicles only.

What happens if I pay full registration fees on a PYR vehicle by mistake?

The vehicle converts to full-year registration status. DMV states that paying full registration, vehicle license and unladen weight or CVRA fees at any point during the year changes the status. Nothing rejects the payment, so flag PYR vehicles in whatever system approves registration invoices.
