Professional Tax in Sikkim (2026): Salary Slabs, Business Rates, Returns and Penalties

Sikkim's professional tax has one of the highest nil limits in India for salaried staff — nothing is due until monthly pay crosses ₹20,000 — but a long, detailed schedule for businesses, with separate turnover bands for traders, contractors, hotels and firms. Employers also file returns every quarter, which surprises businesses used to annual filing elsewhere. This guide is for employers, HR and payroll teams, traders, hoteliers, contractors and professionals in Gangtok, Namchi, Gyalshing, Mangan, Rangpo, Jorethang and the rest of the state. It covers the salary slabs, the business rates, registration and enrolment, due dates, how to pay, penalties and worked rupee examples.

Quick answer

In Sikkim, monthly salary up to ₹20,000 a month is nil; ₹20,001–₹30,000 pays ₹125 a month, ₹30,001–₹40,000 pays ₹150 a month, and above ₹40,000 pays ₹200 a month. Employers file a quarterly return by the end of the month after each quarter with the tax paid; traders, professionals and companies pay their annual tax before 30 September.

• Law: Sikkim Tax on Professions, Trades, Callings and Employments Act, 2006, administered by the Commissioner of Profession Tax in the Commercial Taxes Division

• Register or enrol within 90 days of becoming liable

• Business rates run up to ₹2,500 a year a year

• Interest 2% a month on unpaid tax

Sikkim professional tax slab for 2026

The Sikkim Tax on Professions, Trades, Callings and Employments Act, 2006 (Act 5 of 2006) was published in the Sikkim Government Gazette on 1 April 2006. Section 4 makes everyone in a Schedule class liable at the Schedule rate, and section 5 lets the State Government add to or change the Schedule by notification. The Commercial Taxes Division publishes a consolidated Schedule on sikkimtax.gov.in; its salary entry carries the same rates as the 2006 Act.

One caution: the department's consolidated PDF misprints the boundaries of the middle bands (for example, "₹20,000 or more but less than ₹20,001"). The rates are unambiguous, and the band limits above follow the Act as gazetted, which is also how payroll providers apply them in 2026.

What counts as salary. The Act defines salary or wage to include pay, dearness allowance and every other remuneration received regularly, in cash or kind, including perquisites and profits in lieu of salary — but not bonus or gratuity. So a Diwali bonus does not push an employee into a higher band for that month. Casual wage earners are left out of the definition of a taxable "person" altogether.

Who counts as an employee. The definition covers Central and State Government servants, staff of government-owned or controlled bodies and statutory corporations operating in Sikkim — even if headquartered elsewhere — and anyone employed by any other employer. A national bank or PSU with a Gangtok branch therefore deducts Sikkim professional tax from its Sikkim staff.

Rates for businesses, traders and professionals

The non-salary Schedule is long. Most entries are a fixed annual sum, but four groups are banded by income or turnover, measured on the immediately preceding year.

Several entries have been refined since 2006. Residential hotels now pay by turnover, starting at ₹300 a year for turnover up to ₹1 lakh and rising through ₹500 and ₹1,000 to ₹1,500 for ₹5–10 lakh, with star-category hotels at the top of the scale. The amount column in the department's consolidated PDF is printed out of line with the turnover bands, so confirm your exact band with your tax office. Non-residential hotels pay ₹250 up to ₹5 lakh turnover, ₹1,000 up to ₹20 lakh and ₹2,500 above. Beauty parlours pay by location: ₹300 in rural areas, ₹400 in rural market centres, ₹500 in Rangpo, Jorethang, Namchi, Gyalshing and Mangan, and ₹1,000 in Gangtok proper, Deorali, Tadong and the Development Area. Tradespeople — carpenters, plumbers, welders and electricians — pay ₹250, photo studios ₹500 and conventional motor garages and driving schools ₹1,000.

Two limits sit over all of this. The Constitution caps any one person's professional tax at ₹2,500 a year a year. And the "explanation" notes in the Schedule say several entries (hotels, liquor vendors, companies, chit funds) apply only if the person is not covered by another entry — so read the whole Schedule before settling on your rate.

Who has to pay and who is exempt

Section 4 makes every person engaged in a profession, trade, calling or employment in Sikkim, and falling in a Schedule class, liable at that class's rate. "Person" includes individuals, Hindu undivided families, firms, companies, corporations, societies, clubs and associations. The 2024 public notice from the Commercial Taxes Division lists who it expects to pay: traders including wholesalers, retailers, mela and exhibition organisers and hawkers; hoteliers, resort, guest house, homestay and restaurant owners; manufacturers; banks and insurers; telecom and internet providers; professionals including lawyers, doctors, CAs, architects and journalists; owners of taxis, trucks, buses and earthmovers; courier and delivery businesses; works and service contractors; spas, gyms and beauty parlours; petrol pumps; liquor shops; coaching centres; cinemas and cable networks; casinos; online lottery terminals; and online gaming counters.

Exemptions. Section 33 says the Act does not apply to people subject to the Army, Navy or Air Force Acts who are serving in Sikkim, and lets the State Government exempt any class by notification in the public interest. In practice the "exemptions" most people rely on are the nil bands: salaries up to ₹20,000 a month, professionals with gross income up to ₹25,000 a year, and traders, contractors and firms below ₹1 lakh turnover.

Two employers, or a higher entry. Under section 6, an employee who works for two employers at the same time, or who also falls under a higher-rated non-salary entry (a salaried doctor with a private practice, say), can give each employer a certificate that they will enrol and pay themselves. The employers then stop deducting, and the person pays the higher rate directly.

Temporary breaks. An enrolled person who is temporarily not engaged in their profession, trade or calling in Sikkim during a year need not pay for that year, subject to conditions in the rules (section 13).

   Pay your own annual tax

   Enrolled persons — including the business itself — pay before 30 September.

Registration and enrolment

Section 7 requires every employer (other than a Government officer) liable to deduct tax to obtain a certificate of registration, and every other person liable to obtain a certificate of enrolment. Apply within 90 days of becoming liable. If the application is in order, the prescribed authority must grant the certificate within thirty days. The certificate states the tax payable and the date by which it is due, and it doubles as a notice of demand.

Registration is not just a formality. Section 7(4) makes you liable for tax for the period before registration during which you were liable, so a late applicant pays the back years too. The authority can also, after a hearing, fix the date from which your liability started.

After registration, section 8 requires you to tell the authority within thirty days of any change — a sale or change of ownership, a change in the nature of the business, a change in a company's board, a change of place of work, or closure — with a copy of your certificate. Your legal representative must do this if you cannot.

How employers deduct, pay and file

Section 6 makes every employer deduct the tax from the salary or wage of each liable employee before paying it, and makes the employer liable whether or not it deducted. Government employers follow whatever manner the rules prescribe.

Section 9 sets the return cycle. A "quarter" in the Act is the three months starting 1 April, 1 July, 1 October and 1 January, so each registered employer files:

Apply for registration (employer) or enrolment (others)

Enrolled persons pay the year's tax

31 October

Quarterly return and payment for July–September

31 January

Quarterly return and payment for October–December

30 April

Quarterly return and payment for January–March

Each return must be accompanied by a challan or other accepted proof that the full tax shown in it has been paid; a return without proof of payment is not treated as filed. If you find an error, you can file a revised return as the authority directs. If the authority is not satisfied with a return, it can call for accounts and assess the tax, or assess to the best of its judgment if you do not cooperate; assessed tax is payable within thirty days of the demand.

How to pay

Profession tax is credited to the State's revenue head 0028-107. The Commercial Taxes Division's public notice of April 2024 says the tax can be paid online as a registered member of the Taxpayer Club on sikkimtax.gov.in, or by drawing a bank receipt at any branch of the State Bank of Sikkim under that head. Its April 2023 notice also listed account-payee cheques or demand drafts in favour of the Commissioner of Profession Tax, and NEFT/RTGS to the State's notified tax collection account. Both notices warn that defaulters are liable to interest under section 14. Keep the bank receipt or online acknowledgment: you need it for each quarterly return and as proof against any later demand.

Worked examples in ₹

Example 1 — a hotel receptionist. Pema earns ₹18,000 a month in Gangtok. That is below ₹20,000, so nothing is deducted.

Example 2 — a bank officer. Sonam earns ₹48,000 a month: ₹200 a month, or ₹2,400 a year. A ₹30,000 festival bonus does not change this, because bonus is excluded from salary.

Example 3 — a Namchi hotel with 20 staff. Eight staff earn ₹15,000 (nil), seven earn ₹24,000 (₹125), and five earn ₹35,000 (₹150). Monthly deduction: 7 × ₹125 + 5 × ₹150 = ₹1,625, or ₹4,875 a quarter. The hotel pays it and files the quarterly return by 31 July, 31 October, 31 January and 30 April. As a residential hotel with ₹8 lakh turnover last year, it also pays its own Schedule tax — ₹1,500 on our reading of the ₹5–10 lakh band — by 30 September.

Example 4 — a contractor. A civil contractor in Jorethang billed ₹65 lakh last year. That falls in the ₹50 lakh–₹1 crore band: ₹1,500 for the year, paid by 30 September. Government departments may ask for a clearance certificate before paying her bills (see below).

Example 5 — a young advocate. In her first year of practice an advocate in Gangtok received ₹1,40,000 in fees. Next year her tax is ₹1,000 (the ₹1,10,000–₹1,70,000 band). Once her previous-year fees cross ₹2,70,000, she pays ₹2,500.

Example 6 — a taxi owner. An owner with permits for three taxis pays 3 × ₹500 = ₹1,500 a year.

Penalties, interest and clearance certificates

• Interest (section 14): simple interest at 2% a month (or part of a month) on unpaid tax, for employers and enrolled persons. ₹2,500 paid four months late carries ₹200.
• Not paying a demand (section 15): a penalty of up to 50% of the tax, after a hearing.
• Late registration or enrolment (section 7): up to ₹25 a day for employers and ₹10 a day for others; up to ₹1,000 for deliberately false information.
• Late or false returns (section 9): up to ₹15 a day of delay, or up to ₹1,000 for wilfully incorrect particulars.
• Accounts (section 20): up to ₹100 a day for wilfully failing to keep the accounts and payroll records the Act requires.
• Offences (section 24): on conviction, a fine of up to ₹10,000 (plus up to ₹50 a day if continuing); for a repeat offence, simple imprisonment of up to three months, a fine of up to ₹15,000, or both. The Commissioner can compound an offence for up to double the tax involved (section 27).
• Recovery (sections 16 and 21): arrears are recovered under the Sikkim (Collection of Taxes and Prevention of Evasion of Payment of Taxes) Act, 1987, and the Commissioner can collect directly from people who owe you money.

Clearance certificates. Section 32 is the provision that bites in practice. Government bodies, local authorities, educational institutions and statutory corporations cannot place orders with, buy from or pay a supplier, or award or pay for a contract — and they cannot renew a licence — unless the Commissioner certifies that the person has no unpaid professional tax and no missing returns. Companies and co-operative societies are bound by the same rule for contracts. Contractors and suppliers should keep their professional tax clean all year rather than discover the problem when a bill is held up.

Common mistakes and how to fix them

Deducting from staff under ₹20,000. Sikkim's nil limit is high; payroll set up for a state like West Bengal or Assam can over-deduct. Refund the excess and correct the master.

Filing once a year. Sikkim employers file quarterly, with payment. If you have been filing annually, file the missing quarterly returns and pay interest on late deposits.

Treating bonus as salary. Bonus and gratuity are excluded, so they should not push anyone into a higher band.

Forgetting the business's own tax. Companies, firms, hotels and traders pay their own Schedule tax by 30 September, separate from staff deductions.

Using this year's turnover. Turnover and professional income bands use the previous year's figures.

Staff in other states and income-tax treatment

Professional tax follows the place of work. A Gangtok business with staff in Siliguri applies West Bengal's slabs; staff in Shillong follow Meghalaya's schedule. Our due dates table puts every state side by side, and the state-wise professional tax guide covers the common rules.

Employees can deduct professional tax paid from salary income only under the old income-tax regime; a business can claim its own professional tax as an expense.
