Jaipur Udyog Ltd. a Company registered under the Indian Companies Act	 1913	 established in 1953 a cement factory at Sawai Madhopur in the State of Rajasthan. From time to time the Company filed its returns under the Income tax Act	 1922	 and after the repeal of that Act under the Act of 1961. The following chart sets out the income or loss returned by the Company for the years 1954 55 to 1964 65 and the 195 income or loss computed for the years by the Income tax Officer on assessment: Year of Income or loss returned Income or loss compu Assessment by the Companyted by the1. ted bythe T.0. 1954 55 61	24	270 (Loss)22	53	457(LOSS) 1955 56 14	59	963(Profit)19	84	447(Profit) 1956 57 12	92	958(Profit)16	88	480(Profit) 1957 58 23	05	305(Loss)12	53	222(Loss) 1958 59 46	44	779(Loss)31	48	707(Loss) 1959 60 28	77	487(Loss)20	62	180(Loss) 1960 61 11	35	365(Loss)Assessmentpending. 1961 62 66	086 (Loss) 1962 63 44	93	236 (Profit) 1963 64 7452402 (Profit) 1964 65 59	89	757 (Profit) Against the orders of assessment made by the Income tax Officer for the years 1954 55 to 1959 60 determining its net income or loss as set out in the chart the Company appealed to the Appellate Assistant Commissioner	 and the appeals were pending at the dates of commencement of the petition	 in the High Court of Rajasthan which give rise to the proceedings in this Court. Assessments for the years 1960 61	 1961 62	 1962 63	 1963 64 and 1964 65 were however then not completed. In its return of income for the assessment year 1963 64 the Company claimed to set off against the income returned Rs. 1	03	03	935 being the aggregate amount of loss which it claimed it had suffered in the previous years and was entitled to set off against the income of that year. The Income tax Officer made a provisional assessment of tax under section 141 of the Incometax Act	 1961	 and against the income returned by the Company he allowed deduction of Rs. 39	89	731 as loss carried forward from the earlier years	 and made a demand for Rs. 8	73	873 as tax provisionally due and Rs. 87	387 as penalty for default in compliance with the demand. The Company moved petition No. 51 of 1964 in the High Court of Rajasthan and challenged the order claiming that the Income tax Officer was bound to accept the return made by the Company and could not assess it to tax on income not admitted. For the assessment year 1964 65 the Company returned a net income of Rs. 59	89	757 as profit	 and claimed to set off against that amount Rs. 36	01	735 as loss of the previous years and paid Rs. 12	12	596 65 as tax due by it in accordance with section 140A (1) of the Act. But the Income tax Officer made a provisional assessment and computed the tax on the total income of Rs. 59	89	757 returned by the Company without allowing any deduction claimed and ordered the Company to pay an additional amount of Rs. 17	32	768 60. Against that order the Company moved petition No. 26 of 1965	 for an order quashing the demand 196 of tax and for an injunction restraining the Income tax Officer from enforcing the demand. For the assessment year 1965 66 the Income tax Officer relying upon section 210(3) of the Act called upon the Company to pay Rs. 29	45	365 25 as advance tax. The Company moved petition No. 67 of 1965 in the High Court of Rajasthan	 for an order quashing the demand. The High Court rejected the three petitions. Against the orders passed by the High Court	 these three appeals have been preferred by the Company. Section 141 of the Income tax Act	 1961	 authorises the Income tax Officer to make a provisional assessment of the income of the assessee on the basis of the return made under section 139 and the accounts and documents	 if any	 accompanying the return. The assessment so made is summary and is based only on the return and the accounts and documents filed by the assessee. The Income tax Officer is not bound to make any enquiry before making a provisional assessment: he is not bound even to give to the assessee any notice of his intention to make a provisional assessment	 nor to hear the assessee. He may	 if he desires	 call upon the assessee to elucidate the return or the entries posted in the accounts and documents	 but he is not obliged to do so. Section 141 has been enacted with the object of expediting collection of tax on the basis of the return made by the assessee. The Act contains several provisions for collection of tax before regular assessment	 e.g. payment of advance tax	 deduction of tax at source from salary and dividends	 provision for self assessment etc. The object of these provisions is to collect tax on certain classes of income before regular assessment. The provisional assessment does not bind the assessee nor the Department: the quantum of tax computed and levy thereof are not binding upon the assessee and the Revenue. Tax paid pursuant to provisional assessment is liable to be adjusted in the light of the final order in the regular assessment. An appeal against the order is expressly prohibited. The Income tax Officer must	 however	 apply the rate operative in the assessment year by virtue of the Finance Act and give effect to the allowances mentioned in sub section (2) of section 141 whether the assessee has claimed them or not. But the assessee has no right to be heard or to explain or elucidate and has no right of appeal against the computation or the levy of tax. The Company claimed that it was entitled to deduct the aggregate of losses which it had suffered since the year 1954 55 year after year from the profits of the year 1963 64. It is true that the loss returned by the Company year after year was in excess 197 of the amount of loss determined by the Income tax Officer. But in respect of the orders of assessment appeals were pending. Counsel for the Revenue concedes that assessment under section 141 being provisional	 the Income tax Officer cannot make an enquiry into disputed questions of fact or law	 but he submits	 relying upon sub section (2) of section 141	 that the assessee cannot claim	 and the Income tax Officer cannot allow	 loss in respect of previous years in excess of the loss certified by the Income tax Officer. That he says is the effect of sections 72 and 80 of the Income tax Act	 1961. Section 72 provides: "( 1 ) Where for any assessment year	 the net result of the computation under the head "Profits and gains of business or profession" is a loss to the assessee	 . and such loss cannot be or is not wholly set off against income under any head of income in accordance with the provisions of section 71	 so much of the loss as has not been so set off or	 . or where he has no income under any other head	 the whole loss shall	 subject to the other provisions of this Chapter	 be carried forward to the following assessment year	 and (i) it shall be set off against the profits and gains	 if any	 of any business or profession carried on by him and assessable for that assessment year: Provided that the business or profession for which the loss was originally computed continued to be carried on by him in the previous year relevant for that assessment year; and (ii) if the loss cannot be wholly so set off	 the amount of loss not so set off shall be carried forward to the following assessment year and so on. (2) (3) No loss shall be carried forward under this section for more than eight assessment years immediately succeeding the assessment year for which the loss was first computed. " Section 80 of the Act provides: "Notwithstanding anything contained in this Chapter	 no loss which has not been determined in pursuance of a return filed under section 139	 shall be carried forward and set off under sub section (1 ) of section 72 or " Under section 72(1) read with section 80 loss of a previous year under the head of income from profits and gains of business	 profession 198 or vocation may be carried forward to the next succeeding year only if it has been determined in pursuance of a return filed under section 139. If it is not so determined in the assessment of the subsequent year the loss cannot be carried forward and set off against the profit of the subsequent year or years. By sub section (2) of section 141 the Income tax Officer is enjoined to give effect to the loss so certified and carried forward. But it does not follow therefrom that when the assessee claims that out of the income of the year returned by him certain amounts are liable to be deducted in computing the taxable total income	 the Income tax Officer may adjudicate upon the validity of the claim in making a provisional assessment. In our judgment	 if it be granted that the Income tax Officer has jurisdiction to hold an enquiry into disputed matters	 the expression "provisional assessment" may lose all significance: the income tax Officer may under a summary assessment without giving an opportunity to the assessee to explain his claim negative it and the assessee has no redress under the Act against any erroneous or arbitrary action. The Court would not	 unless compelled by the phraseology of the statute or by the clear implication arising therefrom	 be justified in accepting that view. The clearest implication of section 141 bars an enquiry at the stage of making a provisional assessment into disputed questions of law and fact: it is a matter of no moment that the dispute raised is complicated or is easy of solution. In our judgment	 once a dispute is raised by the assessee the Income tax Officer has no discretion. By sub section (2) of section 141 the Income tax Officer is enjoined to give effect to the provisions of section 32(2)	 72(1)	 73(2) and 74(1) of the Act: sub section (2) does not enlarge his jurisdiction under sub section The High Court was of the view that the basic scheme of the Act is that tax is to be charged at the rate or rates prescribed for the year on the total income of the assessee and in accordance with the provisions of the Act	 and that this basic scheme applies alike to a provisional assessment as to a regular assessment. Consequently in construing the provisions of section 141 of the Act	 assessment of tax must also be made in accordance with and subject to the provisions of the Act	 i.e. in making u provisional assessment the "necessary facts" about the income of the assessee must be taken by the Income tax Officer from the return and the documents accompanying it and he should not travel beyond	 but in making the provisional assessment he cannot ignore the other statutory provisions: he must apply the law correctly to the admitted facts as per return. The High Court proceeded to observe: "The combined effect of the two sections	 namely	 sections 72 and 80 of the Act	 is that a business loss can be carried forward to the subsequent assessment years 199 only when it has been determined in pursuance of a return filed under section 139 of the Act. " The claim of the Company that it was entitled to the benefit of carry forward losses of previous years	 merely because it had shown such losses in the returns	 could not	 in the view of the High Court	 be accepted: to give effect to the claim of the Company	 in the view of the High Court	 will be to ignore the provisions of section 80 which apply both to a regular assessment and a provisional assessment under section 14]. We are unable to accept the opinion of the High Court. If it be assumed that provisional assessment has to be made in accordance with and subject to the provisions of the Act	 distinction between a provisional assessment and a regular assessment gets completely blurred. The scheme of section 141 is to call upon the assessee to pay tax provisionally at the appropriate rate on what he admits is his taxable income	 subject to the benefit of the allowances under sub section The section does not permit an enquiry to be made whether the total income returned by the assessee exceeds the amount admitted by him	 nor whether the allowances or deductions claimed are admissible. If there be a discrepancy between the return made and the accounts and documents accompanying the return	 the Income tax Officer may ask the assessee to explain the discrepancy	 but he must make a provisional assessment on the basis of the return initially made or clarified and the accounts and documents filed. He cannot make a provisional assessment by holding that certain claims made by the assessee are in law unjustified. If it transpires that the assessee has without reasonable cause concealed particulars of his income or has furnished inaccurate particulars of his income	 it may be open to the Income tax Officer to impose penalty upon him after the regular assessment is completed. But it is not open to him to determine whether there has been any concealment of particulars of income or to decide whether claims which have been made are unwarranted. In the view we have expressed	 the Income tax Officer was not justified in holding that the claim made by the Company for carrying forward and seeking to debit against Rs. 74 lakhs odd an amount of Rs. 103 lakhs odd was liable. to be rejected. For the same reasons in making the provisional assessment for the year 1964 65 the Income tax Officer was not entitled to ignore the claim made by the Company that against the income of Rs. 59	89	757 returned	 Rs. 36	01	735 should be permitted to be debited. The order demanding tax of Rs. 17	32	768 60 for the year 1964 65 also was	 in our view	 erroneous. For the year 1965 66 the Income tax Officer demanded payment of advance tax on the provisional assessment for the year 1964 65. It is true that under subs. (3) of section 210 as inserted by of 1963 and later modified by Act 31 of 1964 the Income tax Officer is entitled to make an order for payment of advance tax on the basis of provisional assessment made under section 141	 and he is not obliged to demand advance tax only for the amount provisionally assessed by way of regular assessment in respect of any previous year. Sub section (3) of section 210	 however	 predicates a valid provisional assessment on the basis of which advance tax may be demanded. But the provisional assessment for the year 1964 65 made by the Income tax Officer was invalid	 and tax could not be demanded on that invalid assessment. No order for payment of advance tax for the year 1965 66 could then be made	 relying upon the provisional assessment for the year 1964 65. The appeals will be allowed and the orders passed by the High Court set aside. The orders of provisional assessment made by the Income tax Officer in respect of the years 1963 64 and 1964 65 will be set aside and the order for payment of advance tax for the year 1965 66 is also set aside. There will be no order as to costs in these appeals. The order of penalty in respect of the year 1963 64 is also quashed. V.P.S. Appeals allowed.

The appellant filed its returns for the assessment years 1954 55 to 1964 65. The Income tax Officer passed orders of assessment for the years 1954 55 to 1959 60. While the appeals to the Appellate Assistant Commissioner for those years	 and the	 assessment proceedings before the Income tax Officer for the years 1960 61 to 1962 63	 were still pending	 for the assessment year 1963 64 (the return for which was flied under section 139 of the Income tax Act	 1961)	 the Income tax Officer made a provisional assessment under section 141. He held that the appellant was not entitled to deduct the aggregate amount of losses as claimed by it during the previous years and allowed only a much smaller sum as loss which could be carried forward from the earlier years. For the assessment year 1964 65	 the Income tax Officer made a provisional assessment without allowing any deduction of loss claimed by the appellant; and for the assessment year 1965 66 the Income tax Officer called upon the appellant to pay a certain sum as advance tax under section 210(3). The appellant filed writ petitions in the High Court for quashing the orders of the Income tax Officer for each of the three years	 but the petitions were dismissed. The High Court held: (1) that under section 141 the provisional assessment of tax must also be made in accordance with and subject to the provisions of the Act	 and that the combined effect of sections 72 and 80 was that a business loss can be carried forward to subsequent assessment years only when it has been determined in pursuance of a return flied under section 139; and (2) that under section 210(3) as inserted by Act 13 of 1963 and modified by Act 31 of 1964	 the Income tax Officer was entitled to make an order for payment of advance tax for 1965 66 on the provisional assessment for the year 1964 65. In appeal to this Court	 HELD: (1) Section 141 bars an enquiry	 at the stage of making a provisional assessment	 into disputed questions of law and fact: it is immaterial that the dispute raised is complicated or easy. Therefore the Income tax Officer was not justified. in ignoring the appellant 's claim. [198 D F] Under section 80 loss of a previous year under the head of income from profits and gains may be carried forward only if it has been determined in pursuance of a return filed under section 139; that is	 if it is not so determined it cannot be carried forward and set off against the profit of the subsequent year or years. But the section applies only to a regular assessment. In the case of 'a provisional assessment under section 141	 if there has been such a determination of the allowances mentioned in sub section 2 in a regular assessment for an earlier year	 then under section 141(2) 194 the income tax officer must whether the assessee has claimed or not give effect to the allowances so determined. But he has no power to adjudicate upon a claim for deduction made by the assessee when making a provisional assessment. [196 G; 197 A 198 B; 199 B C] The section has been enacted with the object of expediting collection of tax on the basis of the return made by the assessee. The assessment so made is summary and is based only on the return and the accounts and documents filed by the assessee. If there be discrepancy between the return made and the accounts and documents accompanying the return the Income tax Officer may ask the assessee to explain the discrepancy but he must make a provisional assessment on the basis of the return initially filed or clarified	 but cannot hold that certain claims made by the assessee are in law unjustified. The provisional assessment does not bind the assessee nor the department and the tax paid pursuant to such provisional assessment is liable to be adjusted in the light of the final order in the regular assessment	 and it is open to the Income tax Officer to impose a penalty in appropriate cases after the regular assessment is completed. If it is held that the Income tax Officer has jurisdiction to hold an enquiry into disputed matters	 the expression 'provisional assessment ' loses all significance: the Income tax Officer. may	 under such a summary assessment	 without giving an opportunity to the assessee to explain his claim negative it and the assessee has no redress under the Act against any erroneous or arbitrary action because	 the Income tax OffiCer is not bound to give notice to the assessee or hear witnesses and an appeal against a provisional assessment is expressly barred. [196 D E; 198 B C; B C;199 (2) Under section 210(3) the Income tax Officer is entitled to make an order for payment of advance tax on the basis of provisional assessment under section 141	 but it predicates a valid provisional assessment. Since the provisional assessment in the present case	 for the year 1964 65 is invalid	 an order for payment of advance tax or the year 1965 66 could not be made. [200 A C]
