A common clarification in car-hiring tenders says something like this:
“Quoted rates in the Price Bid should be exclusive of GST. GST will be paid extra as per actuals at the prevailing rate during invoicing. L1 will be determined on the basic fixed monthly rental only.”
This sentence creates a real confusion for fleet operators and procurement teams.
If one bidder charges GST at 5% and another bidder charges GST at 18%, should the buyer compare the GST-inclusive invoice cost or only the pre-GST base rental?
The answer depends on the tender’s price-evaluation clause. If the tender says L1 will be determined on the basic fixed monthly rental only, then GST may be paid extra during invoicing but ignored while deciding L1.
That means the lowest evaluated bidder is not always the bidder with the lowest GST-inclusive bill.
Quick answer
In a car-hiring tender, L1 means the lowest bidder under the tender’s stated evaluation formula. If the tender says rates must be quoted exclusive of GST and L1 will be decided on the basic fixed monthly rental, then GST is normally not part of the L1 comparison.
GST may still be paid over and above the quoted base rental at the applicable rate. But payment treatment and bid-evaluation treatment are two different things.
The confusion: GST is payable, so why is it not counted for L1?
A bidder usually thinks like this:
“If SBI or any buyer has to actually pay GST, then the buyer’s real cost is base price plus GST. So L1 should be decided on the GST-inclusive cost.”
That sounds logical commercially. But tender evaluation does not always work on commercial outflow alone. It works on the formula printed in the tender.
A tender may say three separate things:
- Quote the monthly hiring charge exclusive of GST.
- GST will be paid extra as per actuals at the prevailing rate.
- L1 will be determined on the basic fixed monthly rental only.
When those three statements appear together, the tender is separating:
- the evaluated price, and
- the invoice payable amount.
The evaluated price may be only the base rental. The invoice payable amount may be base rental plus GST.
What “basic fixed monthly rental” usually means
In a car-hiring tender, the basic fixed monthly rental is usually the monthly amount quoted for providing the vehicle, excluding items that the tender treats separately.
Depending on the tender, the fixed monthly rental may include items such as:
| Item | Usually inside fixed monthly rental? |
|---|---|
| Vehicle maintenance | Yes |
| Insurance | Yes |
| Road tax | Yes |
| Permit renewal | Yes |
| Normal parking, if tender says so | Yes |
| Vendor margin / management fee | Often yes |
| Driver wages | Often no, if separately reimbursed |
| Fuel | Often no, if separately reimbursed |
| Toll | Often no, if on actuals |
| GST | No, if quoted exclusive of GST |
The exact list depends on the tender. The important point is this: GST is not automatically part of the base rental merely because it appears on the final invoice.
What it is not
| Misreading | Correct reading |
|---|---|
| “GST is payable, so it must count for L1.” | Not always. If the tender excludes GST from L1, only the base rental is compared. |
| “A 5% GST bidder must always be cheaper than an 18% GST bidder.” | Not for L1 if the evaluation formula ignores GST. |
| “Quoted rate should include GST.” | Not if the tender says rates are to be quoted exclusive of GST. |
| “The buyer decides my GST rate.” | GST rate depends on applicable GST law, contract structure and invoicing treatment. |
| “Lowest invoice total and L1 are the same thing.” | They can be different if taxes are excluded from evaluation. |
Example 1: same base rental, different GST rate
Assume two car-hiring agencies quote the same base monthly rental.
| Bidder | Base monthly rental | GST rate | GST amount | Invoice total |
|---|---|---|---|---|
| A | ₹1,00,000 | 5% | ₹5,000 | ₹1,05,000 |
| B | ₹1,00,000 | 18% | ₹18,000 | ₹1,18,000 |
If the buyer compares the GST-inclusive invoice total, Bidder A is cheaper.
But if the tender says L1 is based on the basic fixed monthly rental only, both bidders are equal for this component because both quoted ₹1,00,000 as base rental.
The tender may still pay GST extra to each bidder as applicable. But the L1 comparison is not necessarily made on ₹1,05,000 versus ₹1,18,000.
It may be made on ₹1,00,000 versus ₹1,00,000.
Example 2: lower base price but higher GST-inclusive bill
Now assume the base rentals are different.
| Bidder | Base monthly rental | GST rate | GST amount | Invoice total |
|---|---|---|---|---|
| A | ₹1,05,000 | 5% | ₹5,250 | ₹1,10,250 |
| B | ₹1,00,000 | 18% | ₹18,000 | ₹1,18,000 |
On the GST-inclusive invoice total, Bidder A is cheaper:
- Bidder A: ₹1,10,250
- Bidder B: ₹1,18,000
But on base rental only, Bidder B is cheaper:
- Bidder A: ₹1,05,000
- Bidder B: ₹1,00,000
So if the tender evaluates only the basic fixed monthly rental, Bidder B may become L1 even though Bidder B’s GST-inclusive invoice is higher.
This is the exact point many bidders miss. The lowest commercial outflow and the lowest evaluated tender price can diverge.
Example 3: why you should not load GST into the quoted base price
Suppose the tender asks bidders to quote monthly hiring charges exclusive of GST.
A bidder wants to receive ₹1,00,000 as base rental and expects GST at 18%.
The wrong way to fill the base-price column may be:
| Base rental column | Problem |
|---|---|
| ₹1,18,000 | This may look like the base rental itself is ₹1,18,000. |
The cleaner way is:
| Base rental column | GST note |
|---|---|
| ₹1,00,000 | GST extra as applicable |
If the tender evaluates only the base-rental column, putting the GST-inclusive number inside that column may make the bid look more expensive than intended.
Always follow the exact price-bid format. If GST has a separate field, use it. If the tender says quote exclusive of GST, do not mix GST into the base rental.
Why bidders argue for GST-inclusive L1
Bidders often raise a fair objection:
“If GST is not available as input tax credit to the buyer, then GST is a real cost. Shouldn’t the buyer compare the final cost?”
Commercially, this argument has force. If the buyer cannot use input tax credit, the GST amount may become part of the buyer’s actual cash outflow.
For example:
| Bidder | Base cost | GST | Total cost to buyer |
|---|---|---|---|
| A | ₹1,65,000 | 5% = ₹8,250 | ₹1,73,250 |
| B | ₹1,65,000 | 18% = ₹29,700 | ₹1,94,700 |
Here the GST-inclusive difference is ₹21,450.
But the procurement answer may still be:
“Bidders must quote base rates exclusive of GST. GST will be paid extra. L1 will be determined on the basic fixed monthly rental only.”
That is why bidders should raise this question before bid submission. Once the tender clarification confirms the evaluation method, the safest approach is to bid according to that method rather than assume a different formula.
Payment buckets vs evaluation buckets
The biggest lesson is that a tender can have two different maps:
- Evaluation map — what decides L1.
- Payment map — what will be paid during the contract.
For example:
| Cost item | May be paid? | May count for L1? |
|---|---|---|
| Basic fixed monthly rental | Yes | Yes |
| GST | Yes, extra as applicable | Not if excluded from L1 |
| Driver wages | Yes, if reimbursable | Not if excluded from L1 |
| Fuel | Yes, if reimbursable | Often no |
| Toll | Yes, usually on actuals | Often no |
| Overtime | Yes, as per contract/statute | Often no |
| Parking | Depends on tender | Depends on whether included in rental |
| Management fee | Usually inside rental | Yes, if inside rental |
This is why the phrase “payable extra” does not automatically mean “counted for L1”.
Where this confusion appears outside car-hiring tenders
The same issue appears in many service contracts, including:
- manpower supply tenders,
- housekeeping tenders,
- security agency tenders,
- facility management tenders,
- logistics tenders,
- vehicle leasing tenders,
- canteen or catering tenders,
- annual maintenance contracts.
Any time a tender says “exclusive of GST” and “GST payable extra”, check the next sentence: does the tender evaluate bids with GST or without GST?
That one sentence changes the entire bidding strategy.
Practical checklist for bidders
Before submitting a car-hiring tender bid, check these points:
1. Is the price column GST-exclusive?
If the format asks for base monthly rental exclusive of GST, quote the base amount only. Do not put GST-inclusive numbers into a GST-exclusive column.
2. Does the tender say GST will be paid extra?
If yes, the buyer may pay GST over and above the base rental during invoicing. But that does not answer the L1 question by itself.
3. Does the tender say how L1 will be determined?
Look for phrases like:
- “L1 will be determined on basic fixed monthly rental only”
- “GST will not be considered for L1”
- “taxes shall be excluded for evaluation”
- “lowest evaluated cost including all taxes”
- “total cost to company”
These phrases decide the comparison formula.
4. Are driver wages excluded from L1 too?
Many car-hiring tenders separate fixed rental from driver wages. If driver wages are reimbursed at actuals or quoted separately, they may be excluded from L1 comparison.
5. Is your management fee in the right bucket?
If the tender says management fee or vendor margin must be included in fixed monthly rental, do not add it to driver wages or statutory reimbursement.
6. Have you modelled both numbers?
For internal pricing, calculate both:
- evaluated base rental, and
- expected invoice total including GST and reimbursables.
A bid can look attractive on one and risky on the other.
7. Have you asked a pre-bid question if the formula is unclear?
If the tender does not clearly say whether L1 is GST-inclusive or GST-exclusive, ask before submission. Do not rely on assumptions after bid opening.
FAQ
Is L1 calculated before GST or after GST?
It depends on the tender. If the tender says L1 is based on the basic fixed monthly rental and GST is payable extra, L1 is calculated before GST. If the tender says evaluation is on total cost including taxes, GST may be counted.
If GST is paid extra, does that mean it is ignored for L1?
Not automatically. “Paid extra” only tells you how invoicing works. You still need to read the evaluation clause to know whether GST is counted for L1.
Can two bidders with different GST rates be compared only on base price?
Yes, if the tender says comparison will be on base price or basic fixed monthly rental. The GST rate may affect invoice value, but not necessarily the evaluated bid price.
What if a 5% GST bidder has a higher base price but lower final invoice?
If L1 is GST-inclusive, the 5% GST bidder may benefit. If L1 is base-rental-only, the bidder with the lower base price may win even if the final GST-inclusive invoice is higher.
Should bidders quote GST separately?
Follow the tender format. If it asks for base rates exclusive of GST, quote the base rate separately and mention GST as applicable only where permitted or required.
Who decides whether GST is 5%, 18% or another rate?
GST treatment depends on GST law, notifications, contract structure, input tax credit conditions and the nature of supply. The tendering authority may say GST is payable as per law, but the bidder should take tax advice for its own invoicing position.
What happens if the GST rate changes during the contract?
Many tenders say GST will be paid at the prevailing rate during invoicing. In that case, the tax component may change without changing the base rental, subject to the final contract terms and applicable law.
Is the buyer wrong to ignore GST for L1?
Not necessarily. A buyer may choose to compare pre-tax base prices for procurement evaluation. Whether that is commercially ideal is a separate question. For bidders, the binding point is the tender’s published evaluation method and any official clarification.
What you should do
If you are bidding for a car-hiring or fleet tender, do not treat “GST extra” as a small footnote. It can change both your bid ranking and your cash-flow model.
Do this before submission:
- Read the price-bid format line by line.
- Identify whether the base rental is GST-exclusive.
- Find the exact L1 evaluation clause.
- Separate base rental, GST, driver wages, fuel, toll and allowances in your costing sheet.
- Do not include GST in the base-rental column unless the tender specifically asks for an inclusive quote.
- If GST-inclusive cost should matter commercially, raise it as a pre-bid query.
- After clarification, follow the final tender/addendum even if your internal cost model uses a different view.
The key rule is simple:
GST can be payable on the invoice but still excluded from the L1 comparison. Your latest tender document decides.
