Subaya Constructions Company Ltd. Vs Tamil Nadu Water Supply and Drainage Board (Madras High Court)

The Hon’ble High Court of Madras (Madurai Bench) held in Subaya Constructions Company Ltd. Vs. Tamil Nadu Water Supply & Drainage Board (W.P.(MD) No. 15967 of 2020 dated: 08.03.2021), that in case of a works contractor who entered in to the contract before the introduction of GST, he is liable to pay tax applicable to the previous VAT regime only but the differential tax liability (GST) has to be   borne by the awarder. This situation arises wherein the rate of GST is higher than that of the rate of tax under the previous VAT regime.

Facts of the Case

♦ The petitioner herein entered into a contract with Tamil Nadu Water Supply And Drainage Board (TWAD Board) for laying Underground Sewerage works for Karaikudi Municipality, Sivagangai District. An agreement was entered into between them on 25.01.2016. The contract agreement reveals that quotation given by the petitioner was inclusive of TNVAT and Excise Duty components. As per Clause 46 of the Contract, deduction at source towards sales tax shall be made at 2% for civil works contract and at 5% for all other works contract as per the provisions of the Tamil Nadu Value Added Tax Act prevailed up to 30.06.2017. With effect from 01.07.2017, GST Regime came into force. The distinction between civil works and other works became irrelevant since all the works contract for construction activities came to be taxed at 12%. Since the tax regime had undergone a change, it became necessary to re-work the terms of the contract.

♦ While so, the Government of Tamil Nadu had considered the prevalent situation and issued G.O.Ms.No.296 Finance (Salaries) Department, dated: 09.10.2017. The Government took note of the fact that the price bid to be quoted should be inclusive of taxes and duties. The supplier, while raising bills and tax invoice post-GST, will now have to collect GST from the purchaser at revised rates of notified percentage of value of supply and remit the same to the respective Government. The entire GST on the supply will have to be finally borne by the purchaser/awarder.

♦ Now the question was how to work it out. The Government came out with a formula as set out in paragraph No.10 of the said Government Order. It provides for three modes of calculation. The relevant paragraph No.10 reads as follows: –

“10. Considering the necessity to provide for a transparent means of estimating subsumed tax, Government direct that the following methodology be adopted for estimating the value of subsumed taxes in the contracted value of work:

a. If the supplier has furnished break up of taxes within the quoted value (bid value) at the time of submission of tenders, it shall be taken as the basis for estimating the value of subsumed tax.

If, after negotiation, the contracted value is less than the bid value, the tax quoted shall be proportionately reduced to arrive at estimate of the value of subsumed tax. For instance, if the bid value was ₹50 lakh and the breakup of tax is Central Excise Duty of ₹1 lakh and VAT or CGST of ₹1 lakh, the corresponding subsumed tax as per his break up of taxes is ₹ 2 lakh and after negotiation, the contracted value was reduced to ₹ 48 lakh, the subsumed tax shall be taken as ₹ 2 lakh x 48/50 = ₹ 1.92 lakh.

b. In case, the breakup of taxes was not obtained or furnished in the bid document, the supplier may be asked to furnish breakup of the taxes within the contracted amount, giving details and explanations and based on this estimate of total subsumed tax shall be arrived. For instance, if for the contracted amount of ₹48 lakh in the example above, the supplier states that the Central Excise Duty is ₹1 lakh and VAT or CGST is ₹1 lakh, after checking the reasonability of his claim, the subsumed tax may be arrived at ₹2 lakh.

c. The estimate of subsumed tax should also be worked out independently from the departmental estimates. Revised Schedule of Rate (SOR) showing basic price and tax components separately are being issued by the Public Works Department. Using the revised SOR, revised departmental estimates for the work without subsumed tax shall be arrived as per normal procedure. The difference between the departmental estimates arrived using earlier SOR with taxes would constitute value of subsumed tax in the value of work. For instance, if the Estimate arrived at using the revised SOR without subsumed taxes is ₹45 lakh and that with earlier SOR with taxes is ₹50 lakh, the value of subsumed taxes in the value of work is ₹5 lakh.

If the contracted value for this same work of ₹50 lakh is ₹55 lakh, i.e. with tender premium of ₹5 lakh, then the value of subsumed tax may be proportionately enhanced (or reduced in case of tender discount or minus tender) as follows: ₹ 5 lakh x 55/50 = ₹5.5 lakh. This method is considered as a good proxy for the actual value of subsumed tax for the purpose of determining the value of supply for payment to the supplier along with taxes under the GST laws.”

Held by the Court  

♦ Now the question that arises for consideration is under which category the petitioner’s case will fall. The stand of the respondents is that the petitioner’s case will fall under paragraph No.10(c). The stand of the petitioner is that the case will fall under paragraph No.10(a).

♦ The agreement between the parties was entered into on 25.01.2016. The nature of work was to provide Underground Sewerage Scheme to Karaikudi Municipality in Sivagangai District including maintenance of the scheme for five years. The contract price was ₹102,63,58,582.00 only.

♦ There can be no doubt that this contract price included cost factor, profit margin and tax component (TNVAT and Excise Duty). There can also be no doubt that during the relevant time (Pre GST period), rate of tax was 2% for civil works contract and 5% for other works contract. There is again no doubt that it has now been enhanced to 12% under the GST. The Government itself has taken a policy decision that this additional tax burden will have to be borne only by the purchaser (TWAD Board in the present case) and not by the contractor (Petitioner). It can be seen from the bid documents that the bill of quantities contains number of items and for each item, the petitioner had quoted a particular rate. It will not be difficult to arrive at the exact price for each item after deducting the tax component. Since the policy that is manifest from G.O.Ms.No.296 of 2017 dated: 09.10.2017 is that this additional tax burden should be taken care of only by the purchaser, the reworking has to be done only in terms of paragraph No.10(a) of the said Government Order and Paragraph No.10(c) of the said Government Order will be applicable only if along with the tender notification, the TWAD Board has also enclosed their schedule of rates. In the case on hand, no such schedule of rates was enclosed. Hence, the contention of the petitioner that the quotation in the instant case was on item wise basis is sustained.

It is also noticed that, the order dated: 01.08.2019 passed by the Principal Seat of the Court in W.P.Nos.21196 and 21198 of 2019 is relating to the petitioner herein –ie the writ petitioner herein was the writ petitioner in those cases also. Therein, the petitioner had entered into a contract with Salem City Municipal Corporation. After analysing the terms of the contract, the writ petitions were disposed of by holding that the parties will be covered by paragraph Nos.10(a) and 12 of G.O.Ms.No.296, Finance(Salaries) Department, dated 09.10.2017. The case on hand is of no different.

♦ For the sake of clarity, a hypothetical situation can also be visualized. If for laying a pipeline, the cost factor and the profit margin of the contractor is ₹00 and the tax is ₹2.00.00, the contract price will be ₹102.00.00. Since GST has enhanced the rate of tax from 2% to 12%, the contract price will have to be re-worked to ₹112.00.00. Regarding the cost factor and profit margin of the contract, there cannot be a contest. As a result of GST, there will be an additional tax liability of 10%. The policy decision of the Government is that this additional tax burden will have to be borne by the Board. In other words, instead of paying ₹102.00 as contract price, they must pay ₹112.00.

♦ It appears that the petitioner had already entered into a revised agreement. According to the petitioner, the petitioner was under compulsion to sign the revised agreement. The officials of TWAD Board had stated that unless the petitioner signed the revised agreement, the Board cannot release the funds. There may not have been any physical coercion or compulsion. However, it can easily be visualized that the petitioner was obviously faced with liquidity crunch and therefore, he signed the revised agreement. But then, it is concerned with the rights of the parties. The question is how the agreement should be reworked. The following order was passed in W.P.(MD) Nos. 21196 and 21198 of 2019: –

“21. Therefore, the parties will now stand governed by paragraph 10(a) and paragraph 12 of aforesaid G.O.Ms. No.296, Finance (Salaries) Department, dated 09.10.2017.

22. The exercise of quantification qua para 10(a) shall be completed by both the parties as expeditiously as possible within 12 weeks from the date of receipt of a copy of this order.

Though obvious it is made clear that work under the aforesaid   contract shall continue without being impeded by this exercise.”

Since the case on hand is similar, the respondent Board is directed to calculate the tax component in the contract price and rework the same in terms of paragraph No. 10(a) of G.O.Ms.No.296, Finance(Salaries) Department, dated 09.10.2017.

♦ At this stage, the respondent has drawn the attention of the Court to paragraph No.11 of the G.O.Ms.No.296, Finance(Salaries) Department, dated 09.10.2017 and submitted that the respondents would undertake the exercise of calculating tax component by applying all the three formulas and the value of the subsumed tax can be arrived at values estimated in (a) or (b) or (c), whichever is higher. The petitioner’s counsel made it clear that the petitioner should not be saddled with tax liability. When the petitioner entered into an agreement with the respondent Board, the contract price comprised three components, namely, cost factor, profit margin and tax component. There cannot be any contest regarding the cost factor and profit margin. The tax liability will have to be borne by the respondent Board. The respondents are directed to rework the terms of the contract and enter into a revised agreement with the petitioner. The writ petition is allowed and the entire exercise shall be concluded within a period of eight weeks from the date of receipt of a copy of the order.
