EV Novated Lease Impact on Child Care Subsidy, HELP & Income Tests

An EV Novated Lease Can Reduce Your Tax — and Still Increase the Income Used for Government Payments

An eligible electric vehicle (EV) novated lease may reduce your taxable income under Australia's Fringe Benefits Tax (FBT) rules.

However, even when FBT is discounted or exempt, the vehicle may generate a Reportable Fringe Benefits Amount (RFBA).

Government income tests use reported income — not just taxable salary.

That means RFBA can affect:

• Child Care Subsidy (CCS)
• HELP repayment income
• Medicare Levy Surcharge (MLS)

Most novated lease calculators show tax savings.

They do not model income-tested interactions.

This page explains how the rules connect — for a broader overview of EVs and FBT, see our guide on Electric Vehicles, FBT and CCS.

Announced 2027 changes: From 1 April 2027, higher-priced EVs are expected to lose the full FBT discount. EVs above $75,000 but below the applicable LCT threshold are expected to receive only a 25% discount on payable FBT. Existing leases are expected to be unaffected. CCSChecker models the announced settings for planning. Read the ministerial announcement or see the full guide: EV Novated Lease FBT Changes From 1 April 2027.

Does an EV Novated Lease Affect Child Care Subsidy?

It can.

CCS is calculated using family Adjusted Taxable Income (ATI).

ATI includes:

• Taxable income
• Adjusted reportable fringe benefits
• Reportable super contributions
• Certain other income components

If an EV lease generates RFBA, ATI may increase.

If ATI increases, your CCS percentage may reduce depending on where your income sits on the CCS taper.

For families near a taper boundary, even moderate RFBA amounts can shift subsidy bands — see CCS income thresholds and steps for the full taper schedule.

The calculator shows your CCS rate before and after the lease.

Does RFBA Count as Income for Centrelink?

Yes — for income-tested purposes.

While RFBA is not cash income, it is included in income measures used to assess government payments.

For CCS, reportable fringe benefits are adjusted and included in ATI.

For HELP and Medicare Levy Surcharge, reportable fringe benefits are included in repayment or surcharge income calculations.

That is why a lease can reduce taxable salary but increase income for testing purposes.

How the EV FBT Discount Works (Current Rules and Announced 2027 Changes)

Under current rules, an EV may qualify for the full EV FBT discount if:

• It is a Battery Electric Vehicle (BEV) or Hydrogen Fuel Cell Vehicle
• It was first held or made available after 1 July 2022
• Its value is below the fuel-efficient Luxury Car Tax threshold

Plug-in hybrids are generally not eligible for new arrangements after 1 April 2025, although transitional rules may apply to earlier eligible arrangements.

Even when the EV FBT discount applies:

• The statutory method is used to estimate taxable value
• FBT is assessed on the FBT year (1 April – 31 March)
• If taxable value exceeds $2,000, a grossed-up RFBA may be reported

From 1 April 2027 (announced, pending final law):

• EVs costing $75,000 or less are expected to keep the full discount
• EVs above $75,000 but below the applicable LCT threshold are expected to receive a 25% discount on payable FBT (75% of normal payable FBT remains)
• Existing leases are expected to be unaffected

CCSChecker models current rules by default. To model the announced 2027 settings, select the relevant car timing option in the calculator.

The calculator applies these rules when estimating eligibility and reportable amounts.

Using a Novated Lease Quote with the Calculator

Once you have a quote from your salary packaging provider, you can enter the pre-tax salary sacrifice deduction directly.

What to enter

Look for the annual pre-tax deduction — the amount sacrificed from your pre-tax salary. Your quote may label it:

• Pre-tax deductions
• Pre-tax salary sacrifice
• Pre-tax component
• Annual salary sacrifice (pre-tax)

If your quote shows a weekly, fortnightly or monthly figure, annualise it:

• Weekly × 52
• Fortnightly × 26
• Monthly × 12

Enter the income you earn before the lease in Step 1. Do not reduce it by the deduction yourself — the calculator does that. Entering pre-tax income that has already had the deduction removed will double-count it.

What not to enter in this field

Do not enter after-tax employee contributions (ECM) here. ECM reduces the car fringe benefit taxable value and may reduce RFBA — but it does not reduce taxable salary. The two are separate and work through different paths. The calculator keeps them separate.

How it changes the result

When a pre-tax deduction is entered, the calculator shows a "Quote inputs used" box in the results.

For a standard employer:

Taxable income before EV lease
− Pre-tax deduction from quote
+ RFBA / income-test add-back
= Estimated income-test income after lease

For a Section 57A exempt employer (PBI, hospital), the CCS path and HELP/MLS path use different RFBA figures — the box shows both:

• HELP/MLS income after lease — uses full RFBA
• CCS-adjusted ATI after lease — uses RFBA × 0.53

If no pre-tax deduction is entered, the calculator still shows a directional estimate based on the RFBA add-back alone.

Calculation Methodology

The EV Household Impact Calculator uses a multi-step rule engine to model the financial interaction:

1. Eligibility Check: Verifies the vehicle qualifies for the FBT discount based on type (BEV/FCEV/PHEV), date first held, and value relative to the Luxury Car Tax fuel-efficient threshold.
2. RFBA Estimation:
   • Calculates Taxable Value using the Statutory Formula method (20% of car value, prorated for days available in the FBT year).
   • Subtracts Employee Contributions (ECM) from the taxable value.
   • If the taxable value exceeds $2,000, it applies the Type 2 Gross-up Rate (1.8868) to determine the Reportable Fringe Benefits Amount (RFBA). 2b. Pre-tax salary sacrifice deduction (optional): If a quote figure is entered, this is subtracted from Person 1's taxable income before the RFBA add-back is applied. Income entered in Step 1 should be the pre-lease figure. The deduction reduces the income-test base; RFBA is then added back on top.
3. Dual-Path Income Testing:
   • CCS Path: Two rules depending on employer type:
     • Standard employer: the full RFBA is counted for CCS income testing (no reduction).
     • Section 57A exempt employer (PBI, public hospital, qualifying charity): Centrelink applies an adjusted amount of RFBA × 0.53, because the FBT rate is 47% (1 − 0.47 = 0.53).
   • HELP/MLS Path: Uses the full grossed-up RFBA to calculate HELP repayment income (leaseholder only) and Medicare Levy Surcharge income.
4. Differential Analysis: Compares the baseline (no lease) against the post-lease scenario to estimate the annual impact across CCS, HELP and MLS. A positive number means better income-test outcomes; a negative number means worse.

A Simple Illustration

Family taxable income: $190,000 Two children in long day care

The EV lease reduces taxable income by $10,000. Income tax decreases.

However, the statutory method produces a taxable value above $2,000. A grossed-up RFBA is reported.

ATI increases. CCS percentage may adjust.

The net outcome depends on where the household sits relative to CCS taper thresholds.

The calculator models this before and after so you can see the difference clearly.

Other Income Tests That May Change

HELP Repayments

HELP repayment income includes reportable fringe benefits.

If RFBA increases repayment income, compulsory repayments may increase.

The calculator estimates this change for the leaseholder. HELP is not double-counted for a partner who is not the leaseholder.

Medicare Levy Surcharge (MLS)

MLS thresholds also include reportable fringe benefits.

If RFBA moves your household into a higher MLS tier and you do not hold eligible private hospital cover, a surcharge may apply.

The calculator estimates this impact where relevant.

Important Edge Cases

Mid-Year Lease Start

FBT year runs from 1 April to 31 March.

If your lease begins partway through the FBT year, only those days are included in the taxable value estimate.

Employee Contributions (ECM)

After-tax employee contributions reduce the car fringe benefit taxable value and may reduce or eliminate RFBA.

ECM is not the same as a pre-tax salary sacrifice deduction. The key difference:

For EVs above $75,000 from 1 April 2027, the calculator can show both the no-contribution scenario and an estimated contribution scenario. Reducing RFBA through after-tax contributions is a trade-off — it helps income tests but reduces take-home pay.

Existing Salary Packaging

If you already salary package other benefits, total RFBA may be higher.

Income tests consider the combined amount.

Public Hospital, PBI or Charity Employees

If you work for a public hospital, Public Benevolent Institution or qualifying charity:

• The EV exemption does not consume your general FBT cap
• The EV can still generate RFBA
• Existing packaged benefits may stack

For CCS income testing, the standard employer path counts the full RFBA with no reduction. For Section 57A exempt employers, Centrelink uses a Centrelink-adjusted amount of RFBA × 0.53 (because the FBT rate is 47%, so 1 − 0.47 = 0.53). HELP repayment income and Medicare Levy Surcharge always use the full RFBA regardless of employer type. The calculator's employer type field controls which path applies.

Child Turning Six

If your youngest child turns six during the financial year, CCS structure may change.

If this coincides with an EV lease commencement, both effects should be considered together.

What the Calculator Shows

The EV Household Impact Calculator:

1. Calculates your baseline position
2. Checks EV eligibility and FBT treatment
3. Estimates taxable value and RFBA
4. If a pre-tax deduction from a quote is entered: subtracts it from taxable income before applying the RFBA add-back, then shows a "Quote inputs used" breakdown
5. Recalculates CCS using household ATI
6. Optionally models HELP repayments (leaseholder) and MLS
7. Shows the estimated annual income-test impact with a positive/negative direction
8. For announced 2027 partial FBT scenarios: shows dual ECM scenarios side by side
9. If no pre-tax deduction is entered: shows a light note prompting you to add it once you have a quote

If no RFBA is generated, income-tested outcomes are unlikely to change.

If RFBA is generated, the tool shows how each system adjusts.

Why Model Before Signing?

A novated lease is typically a 3–5 year commitment.

Lease summaries generally show:

• Estimated tax savings
• Estimated take-home pay

They do not usually model how income-tested systems interact.

Modelling the interaction before signing reduces uncertainty.

Independent Modelling

We do not currently receive leasing commissions.

The calculator applies consistent rules regardless of provider.

Need to Calculate the Lease Itself?

CCSChecker models the family income-test side of an EV lease — CCS, HELP, MLS and RFBA.

If you would like to calculate the full lease cost (monthly repayments, tax savings and residual value), use your salary packaging provider's quote or a specialist novated lease calculator at Novated Lease Guide. Then return here to check how it affects your CCS and other income-tested payments.

Frequently Asked Questions

What is the "Pre-tax deduction from quote" field?

Once you have a novated lease quote, enter the annual pre-tax salary sacrifice deduction from that quote. Your quote may label it "pre-tax deductions", "salary sacrifice" or "annual pre-tax component".

If the quote shows a weekly, fortnightly or monthly figure, annualise it first: weekly × 52, fortnightly × 26, monthly × 12.

The calculator subtracts the deduction from your taxable income before applying the RFBA add-back, then shows a "Quote inputs used" breakdown in the results.

Enter your income before the lease in Step 1. Do not reduce it by the deduction yourself or it will be counted twice.

What is the difference between the pre-tax deduction and ECM?

They are different things in a novated lease quote and work through separate parts of the calculation.

The pre-tax deduction reduces your taxable income. Enter it in the "Pre-tax deduction from quote" field.

ECM (employee contribution method) is an after-tax contribution that reduces the car fringe benefit taxable value and may reduce RFBA. It does not reduce taxable income. Do not enter ECM in the pre-tax field.

Does the EV lease affect my income for Child Care Subsidy?

It can. CCS is assessed on Adjusted Taxable Income (ATI), which includes reportable fringe benefits. If the lease generates RFBA, ATI may increase and your CCS percentage may reduce — even though your taxable income has gone down.

Does an FBT-exempt EV still create RFBA?

It can. An EV may qualify for the FBT discount but the private-use benefit may still be reported as RFBA if the taxable value exceeds $2,000. That RFBA can affect CCS, HELP and Medicare Levy Surcharge income tests.

Does this calculator show total novated lease savings?

No. The calculator focuses on how the EV lease affects income-tested payments: CCS, HELP and Medicare Levy Surcharge. It is not a full lease quote. For monthly repayments, finance costs, residual value and running costs, use your salary packaging provider's quote or a specialist calculator such as Novated Lease Guide.
