Special Duty Allowance

Special Duty Allowance is 10% of basic pay for central staff in the North East, Sikkim and Ladakh from 1 July 2017, with no transfer liability test since 2008.

Special Duty Allowance (SDA) is a central government allowance of 10% of basic pay paid to civilian employees serving in the North Eastern Region, including Sikkim, and in Ladakh, under Department of Expenditure Office Memorandum No. 11/1/2017-E.II(B) dated 18 July 2017, with effect from 1 July 2017. The rate is the same at every level of the pay matrix, and it is paid by virtue of the posting.

The allowance dates from Ministry of Finance OM No. 20014/3/83-E.IV of 14 December 1983, which set it at 25% of basic pay, capped at Rs. 400 a month, for employees with all-India transfer liability. The cap went in 1997 and the transfer liability test in 2008. The 6th Central Pay Commission era rate was 12.5%, and the 7th Central Pay Commission cut it to 10% by the factor of 0.8 it applied to every percentage allowance.

It is not paid alongside Tough Location Allowance, although the employee may keep the old Special Compensatory (Remote Locality) Allowance at 6th CPC rates with it. It stops during suspension and joining time. It also stops for leave, training or tour outside the region beyond full calendar months.

The Andaman and Nicobar Islands and Lakshadweep are not SDA areas. They have their own order, the Island Special Duty Allowance at 10%, 16% or 20% of basic pay. The Special Duty Allowance is taxable in full under both tax regimes. It is one of the location allowances in the allowances for central government employees framework.

The rate and the governing order

The Special Duty Allowance is 10% of basic pay under paragraph 1 of DoE OM No. 11/1/2017-E.II(B) dated 18 July 2017, which was issued “in supersession of all existing orders issued on the subject” and took effect from 1 July 2017 under paragraph 5. The order was signed by Joint Secretary Annie George Mathew and carries seven paragraphs.

ParagraphWhat it provides
1SDA at 10% of basic pay for central government employees serving in the North Eastern Region and Ladakh
2Basic pay means the pay drawn in the prescribed level of the pay matrix, excluding special pay and any other type of pay
3Not admissible with Tough Location Allowance; option of the old remote locality allowance at 6th CPC rates plus SDA
4Not admissible for leave, training or tour beyond full calendar months outside the region, or during suspension and joining time
5Effective 1 July 2017
6Applies to civilians paid from the Defence Services Estimates; separate orders for the armed forces and the Railways
7Issued with the concurrence of the Comptroller and Auditor General for the Indian Audit and Accounts Department

The rate has no tiering by level, cadre or group. The 7th CPC report records at paragraph 8.17.115 that the allowance stood at 37.5% of basic pay for All India Services officers and 12.5% for other employees, and paragraph 8.17.118 recommended 30% and 10% respectively, “in line with our general approach of rationalizing the percentage based allowances by a factor of 0.8”. The government accepted the 10% civilian rate in Department of Expenditure Resolution No. 11-1/2016-IC dated 6 July 2017, and the OM of 18 July 2017 implements it.

The base is narrow. Paragraph 2 confines basic pay to the pay in the level of the pay matrix, so special pay, deputation (duty) allowance and every other element are left out. The 2008 order had been wider, computing 12.5% on revised basic pay plus non-practising allowance where applicable. The 2017 text drops the reference to non-practising allowance and defines basic pay as the pay in the level alone.

What the allowance pays at each level

At 10% of basic pay, the Special Duty Allowance at the entry cell of the 7th CPC pay matrix runs from Rs. 1,800 a month at Level 1 to Rs. 18,220 at Level 15. The table is a salary-calculator.in computation for selected levels from the entry pay of each level in the CCS (Revised Pay) Rules, 2016.

15Rs. 1,82,200Rs. 18,220Rs. 2,18,640

The allowance rises with each annual increment of about 3%, and with each promotion or financial upgradation, without any separate order. And it does not move with dearness allowance: the 7th CPC device that raises a fixed-rupee allowance by 25% each time dearness allowance rises by 50% applies only to allowances stated in rupees, which is why the Tough Location Allowance rates rose 25% from 1 January 2024, when dearness allowance reached 50%, under paragraph 2 of DoE OM No. 3/1/2017-E.II(B) dated 19 July 2017, and the Special Duty Allowance did not.

Where the allowance is paid

The Special Duty Allowance is paid in the North Eastern Region, which includes Sikkim, and in Ladakh, an area built up by orders of 1983, 1998 and 2008.

AreaIncluded fromOrder
Assam, Meghalaya, Manipur, Nagaland, Tripura, and the then Union Territories of Arunachal Pradesh and Mizoram1 November 1983Ministry of Finance OM No. 20014/3/83-E.IV dated 14 December 1983
Sikkim1 August 1997DoE OM No. 11(2)/97-E.II(B) dated 22 July 1998
Ladakh1 September 2008DoE OM No. 11(5)/2008-E.II(B) dated 29 August 2008, paragraph 4

The 2008 order’s subject line reads “North Eastern Region (including Sikkim) and Ladakh”, and paragraph 4 extends to Ladakh the allowance “allowed to the Government employees including All India Service Officers posted in North Eastern Region including Sikkim”. The 2017 order names “the North Eastern Region and Ladakh” and does not list the states, so the area carries over from the 1983, 1998 and 2008 orders it superseded. The Ladakh entry predates the Union Territory of Ladakh, formed on 31 October 2019, and no order has restated the SDA area since the reorganisation.

The islands are a different scheme. Employees in the Andaman and Nicobar group of Islands and in Lakshadweep draw the Island Special Duty Allowance under DoE OM No. 12/1/2017-E.II(B), also dated 18 July 2017, at 10% around Port Blair, Kavaratti and Agatti, 16% in the difficult areas and 20% in the more difficult areas such as the Nicobar group and Minicoy. That order allows the island allowance in addition to the Hard Area Allowance of DoE OM No. 13/1/2017-E.II(B) dated 14 July 2017. The mainland SDA order has no counterpart provision.

Who is eligible

Every central government civilian employee serving in the North Eastern Region or Ladakh is eligible, whatever the level, group or cadre, and whether posted from outside the region or recruited within it. Eligibility has been by posting alone since 1 September 2008.

Paragraph 6 of the 2017 order extends it to civilians paid from the Defence Services Estimates, with the cost charged to the relevant Defence head. Paragraph 7 covers the Indian Audit and Accounts Department, the order having issued with the concurrence of the Comptroller and Auditor General of India. For armed forces personnel and railway employees, paragraph 6 states that separate orders “will be issued” by the Ministry of Defence and the Ministry of Railways. The railway order is described in its own section below.

Employees of autonomous bodies, central public sector enterprises and state governments are outside the order, which is addressed to the ministries and departments of the Government of India. An autonomous body applies it by its own adoption: the Council of Scientific and Industrial Research did so for its laboratories by circular No. 5-1(302)/2015-PD dated 21 September 2017.

The all-India transfer liability condition and its removal

Until 31 August 2008 the allowance was confined to employees with all-India transfer liability. Paragraph 1(iii) of the 1983 OM granted it to “Central Government civilian employees who have All-India transfer liability”, and the 1988 and 1998 revisions kept the test. The purpose was to attract officers from elsewhere in the country to serve in the region, which is also how the Supreme Court read the scheme.

In Union of India v. S. Vijayakumar, decided on 20 September 1994 and reported at (1994) Supp (3) SCC 649, the Supreme Court held that employees who were residents of the North Eastern Region were not entitled to the allowance merely because their posts carried all-India transfer liability, and directed that amounts already paid were not to be recovered. The Court followed it in Chief General Manager (Telecom) v. Rajendra Ch. Bhattacharjee on 18 January 1995 and in Union of India v. Executive Officers Association Group C on 23 February 1995. Paragraph 2 of the 2008 OM records the position it replaced: the allowance was admissible “to those employees who are posted from outside the region having ‘All India Transfer Liability’”, under the 1998 OM and OM No. 11(5)/97-E.II(B) dated 29 May 2002.

The 6th CPC order ended the condition. Paragraph 2 of DoE OM No. 11(5)/2008-E.II(B) dated 29 August 2008 made the allowance payable at 12.5% “irrespective of whether the transfer (including on initial appointment) is from outside the North Eastern Region or from another area of that region”, and added: “The existing condition that employees should have All India Transfer Liability has also been dispensed with.” The change took effect on 1 September 2008. The Calcutta High Court, in a judgment of 19 February 2024, recorded that the precondition of all-India transfer liability was dispensed with by the circular of 29 August 2008.

The 2017 order restates no condition of residence or transfer liability. A local recruit appointed to a central post in Shillong or Imphal therefore draws SDA from the date of joining. The Vijayakumar line of cases governs claims only for periods before 1 September 2008.

In Director General, CRPF v. Janardan Singh, decided on 2 July 2018 in Civil Appeal No. 5850 of 2011, the Supreme Court struck down a different restriction under the old scheme: a 1987 condition that Central Para-Military Force personnel also had to have their headquarters in the region. The Court held that the condition failed Article 14 of the Constitution. That judgment concerns the pre-2008 scheme and does not alter the 2017 order.

Tough Location Allowance and the remote locality option

The Special Duty Allowance cannot be drawn with Tough Location Allowance, but the employee may keep the old Special Compensatory (Remote Locality) Allowance at 6th CPC rates alongside SDA at 10%. Paragraph 3 of DoE OM No. 11/1/2017-E.II(B) dated 18 July 2017 reads: “Special Duty Allowance will not be admissible along with Tough Location Allowance.” Its second sentence gives employees “the additional option to avail of the benefit of Special Compensatory (Remote Locality) Allowance (SCRLA) as per 6th Central Pay Commission rates along with Special Duty Allowance at revised rates.”

Paragraph 8 of the Tough Location Allowance order, DoE OM No. 3/1/2017-E.II(B) dated 19 July 2017, states the same choice from the other side. The bar itself comes from the 7th CPC report at paragraph 8.10.63, which says that Tough Location Allowance “will, however, not be admissible along with Special Duty Allowance”. The option to keep the old remote locality rate is an addition the government made when it accepted the report.

The employee chooses one package:

PackageWhat is paidHow it grows
Tough Location Allowance aloneThe 7th CPC rate for the place’s tier (TLA-I, II or III), which rose 25% from 1 January 202425% each time dearness allowance on 7th CPC pay rises by 50%
Old remote locality allowance plus SDASCRLA at the 6th CPC rate for the place’s Part, plus SDA at 10% of basic paySDA rises with every increment; the SCRLA amount stays at the 6th CPC rate

The option exists only where the place carried the remote locality allowance under the 6th CPC, and the places are listed in Annexures I to IV of DoE OM No. 3/1/2017-E.II(B) dated 19 July 2017; in the SDA area they are remote locality places in Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura and Leh. The bad climate, tribal area and Sunderban allowances subsumed in Tough Location Allowance have no counterpart option. The Tough Location Allowance article works out the break-even by Part and level: for every employee at Level 9 and above, and for every employee in a Part D place, the old remote locality allowance plus SDA pays more.

The SDA is also distinct from the risk and hardship allowance matrix, of which Tough Location Allowance forms cells R3H1, R3H2 and R3H3. The matrix pays for a duty or a place, cell by cell. The SDA pays a flat percentage to everyone serving in a notified region. Only the Tough Location cells carry the express bar.

Leave, tour, training, suspension and joining time

Paragraph 4 of the 2017 order withdraws the Special Duty Allowance in two situations. The first sentence covers absence from the region: SDA “shall not be admissible during the periods of leave/training/tour etc. beyond full calendar month(s), in case, the employee is outside the North-Eastern Region and Ladakh during leave/training/tour etc.” The second sentence is absolute: “The allowance shall not be admissible during suspension and joining time.”

SituationSDA paid?Basis
Earned leave or tour spent inside the regionYesParagraph 4 bars only absences outside the region; no other provision withdraws it
Leave, training or tour outside the region, shorter than one full calendar monthYesParagraph 4 bars only periods beyond full calendar months
Leave, training or tour outside the region beyond full calendar monthsNo, for the period the bar reachesParagraph 4, first sentence; the extent depends on the reading below
SuspensionNoParagraph 4, second sentence
Joining time on transfer into or out of the regionNoParagraph 4, second sentence

The phrase “beyond full calendar month(s)” has no published Department of Expenditure clarification, and it reads two ways. Read as a test of whole calendar months, the bar applies only to calendar months spent entirely outside the region: 45 days of earned leave outside the region from 10 March to 23 April then costs nothing, because neither month was spent fully outside, and leave from 1 March to 15 April costs the March allowance only. Read as a test of duration, the allowance stops for the part of the absence that runs past one full calendar month, which costs part of April in the first example. Drawing and disbursing officers apply the order as their accounts office directs.

FR 53(1)(ii)(b) pays a suspended employee the compensatory allowances drawn on the date of suspension only subject to the conditions laid down for their drawal, and the paragraph 4 bar is one of those conditions, so SDA is not paid with subsistence allowance. The Island Special Duty Allowance order carries an identically worded paragraph, so the two allowances are treated alike.

All India Services officers in the North East

Officers of the All India Services in the North East cadres draw two allowances: a Special Allowance at 20% of basic pay and the Special Duty Allowance at 10%. The 7th CPC recommended a single 30% SDA for these officers at paragraph 8.17.118, reasoning at paragraph 8.17.117 that “AIS officers are allotted cadres, irrespective of their choice”. The government kept the two-allowance structure instead and cut each by the 0.8 factor.

AllowanceRate to 30 June 2017Rate from 1 July 2017
Special Allowance for officers of the North East cadres of the All India Services25% of basic pay20% of basic pay
Special Duty Allowance12.5% of basic pay10% of basic pay
Combined37.5%30%

The decision is in Department of Expenditure Resolution No. 11-1/2016-IC dated 6 July 2017, which records the earlier 25% rate as granted by DoPT OM No. 14017/4/2005-AIS(II) dated 10 February 2009. The Department of Personnel and Training sent the resolution to the Chief Secretaries by letter No. 11022/1/2017-AIS-II dated 25 July 2017. The combined 30% matches the Commission’s figure; only the split differs. The Indian Administrative Service, the Indian Police Service and the Indian Forest Service are all covered by the Resolution and the DoPT letter.

Railways and the Central Armed Police Forces

Railway employees draw SDA under their own order, on the same terms as civilians. Railway Board letter RBE No. 88/2017, No. F(E)I/2017/AL-4/2 dated 10 August 2017, pays railway employees serving in the North Eastern Region and Ladakh 10% of basic pay from 1 July 2017, with the same bars for leave, training and tour beyond full calendar months outside the region, suspension and joining time. It cites “MOF’S OM NO. 11/1/2017-E.II(B) dated 18.07.2017” as its authority. The wider railway employees pay framework is in the Railway Services (Revised Pay) Rules, 2016.

For the Central Armed Police Forces, the 7th CPC report at paragraph 8.15.24 gave personnel a choice between two packages: Detachment Allowance plus either SDA or Tough Location Allowance where applicable, or Risk and Hardship Allowance plus Ration Money Allowance. The Ministry of Home Affairs order on the CAPF package, OM No. II-27012/40/CF-3396706/2017-PF-I dated 31 July 2017, is cited in a CRPF Directorate signal of 8 April 2019. Before 2017, an MHA letter of 3 August 2005 had extended SDA to Central Para-Military Force personnel working in the region, as recorded by the Supreme Court in Janardan Singh.

For the armed forces, paragraph 6 of the DoE order leaves the matter to a separate Ministry of Defence order, and the civilian order does not itself reach uniformed personnel.

How the allowance sits with HRA, pension and NPS

The Special Duty Allowance is paid on top of house rent allowance and does not enter pension, gratuity or the NPS contribution. HRA turns on the city classification of the station, at 30%, 20% or 10% of basic pay in X, Y and Z class cities, the rates in force since 1 January 2024 under DoE OM No. 2/5/2017-E.II(B) dated 7 July 2017, and nothing in the 2017 SDA order restricts it. An employee at Level 7 on Rs. 44,900 in a Z-class town in Assam draws SDA of Rs. 4,490 and HRA of Rs. 4,490 a month, each computed on basic pay independently of the other.

For retirement benefits, Rule 31(1) of the CCS (Pension) Rules, 2021 defines emoluments as basic pay under FR 9(21)(a)(i) of the Fundamental Rules plus non-practising allowance. SDA is outside that definition, so years of SDA in the region do not raise the pension or the retirement gratuity. Under the National Pension System, Rule 5(1) of the CCS (Implementation of National Pension System) Rules, 2021, notified by G.S.R. 227(E) dated 30 March 2021, limits the contribution base to basic pay, non-practising allowance and dearness allowance, so neither the employee’s 10% nor the government’s 14% is computed on SDA. The Unified Pension Scheme runs on the same base, and its assured payout of 50% of the average basic pay of the last 12 months leaves SDA out as well.

Leave encashment on retirement under Rule 39(2)(a) of the CCS (Leave) Rules, 1972 is computed on the pay admissible on the date of retirement plus the dearness allowance admissible on that date, so SDA does not enter it either.

The history of the rate

The percentage has changed twice since 1983, in 1988 and in 2017; the ceiling went in 1997 and the base widened to include non-practising allowance in 2008.

From 1 July 201710% of basic payNoneNoDoE OM No. 11/1/2017-E.II(B) dated 18 July 2017

The 1983 OM also stated that employees exempt from payment of income tax were not eligible; the 1988 OM reversed this for Scheduled Tribe employees exempt from income tax, who “will also draw Special (Duty) Allowance”. The 1998 OM continued the 12.5% rate “without any ceiling on its quantum” from 1 August 1997. The 2008 OM kept the 12.5% rate the 6th CPC inherited and widened the base to include non-practising allowance.

The 7th CPC rate of 10% is the first fall in the percentage since 1988, and the revised rate took effect on 1 July 2017, not with the new pay on 1 January 2016. Paragraph 2 of Department of Expenditure Resolution No. 11-1/2016-IC dated 6 July 2017 kept every allowance at its existing rate in the existing pay structure, “as if the pay had not been revised” from 1 January 2016, so SDA for January 2016 to June 2017 was 12.5% of pre-revised pay. A direct recruit at grade pay Rs. 4,600 on the 6th CPC entry pay of Rs. 17,140 drew SDA of Rs. 2,142.50 at 12.5% up to 30 June 2017; the same post’s entry pay at Level 7 is Rs. 44,900, which has drawn Rs. 4,490 at 10% since 1 July 2017.

Tax treatment

The Special Duty Allowance is fully taxable as salary under both the old regime and the default new regime of the Income-tax Act, 2025. The allowances that Schedule III Table serial 13 exempts are prescribed by rule 280(2) of the Income-tax Rules, 2026, notified by Central Board of Direct Taxes Notification No. 22/2026, G.S.R. 198(E), dated 20 March 2026, and none of its fifteen serials names the Special Duty Allowance.

The nearby entries cover other allowances. Serials 1, 2 and 3 exempt the remote locality allowance for places under Tough Location Allowance-I, II and III, up to Rs. 7,000, Rs. 4,500 and Rs. 1,500 a month. An employee who keeps the old remote locality allowance alongside SDA under the paragraph 3 option claims those caps for the remote locality amount in the old regime, while the SDA stays taxable. Serial 14 exempts the Island Special Duty Allowance at 10%, 16% and 20% of basic pay, but only for a member of the armed forces.

In the default regime, Section 202(2)(a)(ii) of the Income-tax Act, 2025 computes income without the serial 12 and 13 exemptions other than those rule 280(3) preserves, so the remote locality caps fall away too. For the financial year 2025-26 the return follows Section 10(14) of the repealed Income-tax Act, 1961 read with Rule 2BB(2) of the Income-tax Rules, 1962, which had no SDA entry either. The comparison of the two regimes is in old versus new tax regime, and the amount appears in Form 16 with the rest of salary. The wider picture is in income tax for government employees.

The 8th Central Pay Commission

The 8th Central Pay Commission has made no recommendation on allowances, so no revised SDA rate exists. Until an order replaces DoE OM No. 11/1/2017-E.II(B) dated 18 July 2017, SDA remains 10% of basic pay. Because it is a percentage, a new pay matrix would raise the rupee amount automatically even if the percentage were left untouched, as happened on 1 July 2017.

Frequently Asked Questions (FAQs)

What is the Special Duty Allowance rate under the 7th CPC?
It is 10% of basic pay, the same percentage at every level of the pay matrix, under Department of Expenditure Office Memorandum No. 11/1/2017-E.II(B) dated 18 July 2017, with effect from 1 July 2017. The 7th Central Pay Commission reached 10% by applying its factor of 0.8 to the earlier 12.5% (report paragraph 8.17.118). An employee on Rs. 44,900, the entry pay of Level 7, draws Rs. 4,490 a month.
Which areas qualify for the Special Duty Allowance?
The North Eastern Region and Ladakh. The 1983 scheme covered Assam, Meghalaya, Manipur, Nagaland and Tripura and the then Union Territories of Arunachal Pradesh and Mizoram. Sikkim was added from 1 August 1997 by DoE OM No. 11(2)/97-E.II(B) dated 22 July 1998, and Ladakh from 1 September 2008 by paragraph 4 of DoE OM No. 11(5)/2008-E.II(B) dated 29 August 2008. The Andaman and Nicobar Islands and Lakshadweep have a separate allowance, the Island Special Duty Allowance.
Is all-India transfer liability still a condition for the Special Duty Allowance?
No. From 1983 the allowance was confined to civilian employees with all-India transfer liability, and the Supreme Court in Union of India v. S. Vijayakumar (20 September 1994) held that residents of the region were not entitled under that scheme. DoE OM No. 11(5)/2008-E.II(B) dated 29 August 2008 dispensed with the condition from 1 September 2008 and made the allowance payable whether the transfer, including initial appointment, was from outside the region or from within it. The 2017 order supersedes all earlier orders and imposes no such condition.
Can a local resident of the North East appointed in the region draw the Special Duty Allowance?
Yes, since 1 September 2008. The 2008 order made the allowance admissible irrespective of whether the transfer, including on initial appointment, is from outside the North Eastern Region or from another area of that region. The 2017 order pays it to central government employees serving in the North Eastern Region and Ladakh without any residence or transfer condition. Court rulings denying it to local recruits concern periods before 1 September 2008.
Can an employee draw both Special Duty Allowance and Tough Location Allowance?
No. Paragraph 3 of DoE OM No. 11/1/2017-E.II(B) dated 18 July 2017 bars the Special Duty Allowance alongside Tough Location Allowance. The employee may instead take the old Special Compensatory (Remote Locality) Allowance at 6th CPC rates together with the Special Duty Allowance at 10%. Paragraph 8 of the Tough Location Allowance order, DoE OM No. 3/1/2017-E.II(B) dated 19 July 2017, states the same option from the other side.
Is the Special Duty Allowance paid during leave, tour or training?
Only up to a point. Paragraph 4 of the 2017 order stops the allowance for periods of leave, training or tour beyond full calendar months when the employee is outside the North Eastern Region and Ladakh. Leave or tour spent inside the region, and absences outside it shorter than a full calendar month, do not trigger the bar. The allowance is not paid at all during suspension and joining time.
Do IAS, IPS and IFoS officers of the North East cadres get a higher Special Duty Allowance?
No higher SDA rate, but a second allowance. The 7th CPC recommended 30% for All India Services officers (paragraph 8.17.118). The government instead kept two allowances for officers of the North East cadres: a Special Allowance cut from 25% to 20% of basic pay and the Special Duty Allowance cut from 12.5% to 10%, under DoE Resolution No. 11-1/2016-IC dated 6 July 2017, sent to the States by DoPT letter No. 11022/1/2017-AIS-II dated 25 July 2017.
Do railway employees get the Special Duty Allowance?
Yes, under their own order. Railway Board letter RBE No. 88/2017, No. F(E)I/2017/AL-4/2 dated 10 August 2017, pays railway employees serving in the North Eastern Region and Ladakh 10% of basic pay from 1 July 2017, on the same leave, tour, suspension and joining-time conditions, citing the DoE OM of 18 July 2017 as its authority.
Does the Special Duty Allowance count for pension, gratuity or NPS contributions?
No. Rule 31(1) of the CCS (Pension) Rules, 2021 defines emoluments for pension and gratuity as basic pay under FR 9(21)(a)(i), plus non-practising allowance, and leaves out allowances such as SDA. Rule 5(1) of the CCS (Implementation of National Pension System) Rules, 2021 limits the NPS contribution base, for the employee’s 10% and the government’s 14%, to basic pay, non-practising allowance and dearness allowance, which also leaves SDA out. The Unified Pension Scheme uses the same base.
Is the Special Duty Allowance taxable?
Yes, in full, under both the old and the default new regime. The Table in rule 280(2) of the Income-tax Rules, 2026, which prescribes the exempt allowances under Schedule III serial 13 of the Income-tax Act, 2025, has no entry for the Special Duty Allowance. Its serial 14 covers only the Island Special Duty Allowance, and only for a member of the armed forces.
Does the Special Duty Allowance rise when dearness allowance rises?
No. The 7th CPC rule that raises fixed-rupee allowances by 25% each time dearness allowance rises by 50% does not apply to percentage allowances. The Special Duty Allowance is 10% of basic pay, so it rises with every annual increment and every promotion instead.
What is the difference between the Special Duty Allowance and the Island Special Duty Allowance?
They are separate orders for separate areas. The Special Duty Allowance is a flat 10% of basic pay in the North Eastern Region and Ladakh under DoE OM No. 11/1/2017-E.II(B). The Island Special Duty Allowance is 10%, 16% or 20% of basic pay by area in the Andaman and Nicobar Islands and Lakshadweep under DoE OM No. 12/1/2017-E.II(B), both dated 18 July 2017.
Is HRA paid along with the Special Duty Allowance?
Yes. House rent allowance depends on the city class of the station and nothing in the 2017 SDA order bars it, so an employee in Guwahati or Shillong draws both. Neither allowance is computed on the other: SDA is 10% of basic pay, and HRA is a percentage of basic pay set by the city class.
What will the 8th CPC do to the Special Duty Allowance?
Nothing is known yet. The 8th Central Pay Commission has made no recommendation on allowances, so no 8th CPC rate for the Special Duty Allowance exists. Until a new order issues, the 10% rate under DoE OM No. 11/1/2017-E.II(B) dated 18 July 2017 continues to apply.
