A professional tax calculator answers a question every salaried employee in a PT-levying state eventually asks: how much is being deducted from my salary, and why? Professional tax is a state-level levy on income from employment, trade, or profession, authorised under Article 276 of the Indian Constitution. The amount varies dramatically by state — Maharashtra deducts up to ₹2,500 annually, Karnataka follows a different threshold, Tamil Nadu collects half-yearly, and Delhi does not levy PT at all. A state-aware calculator eliminates the guesswork and shows you exactly what your payslip should reflect.
Professional tax, often abbreviated as PT, is a direct tax imposed by state governments on individuals who earn income from employment, a profession, a trade, or a calling. Despite the name, it applies to all salaried employees — not just doctors, lawyers, and chartered accountants. If you draw a salary in a state that levies PT, your employer is legally obligated to deduct the applicable amount each month and remit it to the state exchequer. The deduction appears on your payslip alongside PF, income tax TDS, and other statutory deductions.
The constitutional ceiling matters here. Article 276 caps the maximum professional tax at ₹2,500 per person per year. No state can collect more than this, regardless of income level. Some states operate below the cap — Karnataka and West Bengal collect a maximum of ₹2,400 annually, while Kerala's highest slab yields ₹1,500 per year. The variation reflects each state's fiscal policy, not a difference in legal authority.
Self-employed professionals follow a different route. They cannot rely on an employer to deduct PT. Instead, they must register with the state's professional tax authority, obtain an enrolment certificate, and pay the tax directly at the prescribed frequency. In several states, newly registered professionals enjoy a five-year exemption before PT liability begins.
The calculation follows a slab-based structure. Your gross monthly salary determines which slab applies, and the corresponding tax amount is deducted. The process is not a flat percentage — it is a fixed amount per slab, which means a small increase in salary can push you into a higher deduction bracket.
Here is the step-by-step method:
A professional tax calculator automates this entire sequence. Enter your state and monthly salary, and it returns the monthly deduction, the annual liability, and the February or March adjustment — no manual slab lookup required.
Slab structures differ by state in three dimensions: the salary thresholds, the deduction amounts, and the frequency of collection. The table below covers the major PT-levying states. Rates are indicative and reflect the current schedules; always verify against your state's official PT portal before processing payroll.
| Monthly Salary (₹) | Male (₹/month) | Female (₹/month) |
|---|---|---|
| Up to 7,500 | Nil | Nil |
| 7,501 – 10,000 | 175 | Nil |
| Above 10,000 | 200 (300 in February) | Nil up to 25,000 |
| Above 25,000 | 200 (300 in February) | 200 (300 in February) |
Maharashtra is unique for its gender-based slabs. Women earning up to ₹25,000 per month are exempt from PT entirely. Above that threshold, they pay the same rate as men. The annual liability for men above ₹10,000 is ₹2,500 — calculated as ₹200 × 11 months plus ₹300 in February.
| Monthly Salary (₹) | PT (₹/month) |
|---|---|
| Up to 25,000 | Nil |
| Above 25,000 | 200 (300 in February) |
Karnataka revised its threshold to ₹25,000 per month. Below that, no PT is deducted. Above it, the annual total reaches ₹2,500 through a ₹300 deduction in February. The state's portal is at pt.kar.nic.in.
| Half-Yearly Income (₹) | PT per Half-Year (₹) |
|---|---|
| Up to 21,000 | Nil |

| 60,001 – 75,000 | 1,025 |
| Above 75,000 | 1,250 |
Tamil Nadu levies PT on a half-yearly basis — April to September and October to March. The slab is based on total income earned in that six-month period, not monthly salary. Women are exempt from PT in Tamil Nadu. The maximum annual PT is ₹2,500 (₹1,250 × 2 half-years).
| Monthly Salary (₹) | PT (₹/month) |
|---|---|
| Up to 10,000 | Nil |
| 10,001 – 15,000 | 110 |
| 15,001 – 25,000 | 130 |
| 25,001 – 40,000 | 150 |
| Above 40,000 | 200 |
West Bengal has one of the most granular slab structures, with four deduction tiers above the nil threshold. The annual maximum is ₹2,400.
| Monthly Salary (₹) | PT (₹/month) |
|---|---|
| Up to 5,999 | Nil |
| 6,000 – 8,999 | 80 |
| 9,000 – 11,999 | 150 |

|---|---|
| Up to 11,999 | Nil |
| 12,000 – 17,999 | 120 |
| 18,000 – 29,999 | 180 |
| 30,000 – 44,999 | 300 |

| Above 1,25,000 | 1,250 |
Kerala collects PT half-yearly, with the highest annual liability reaching ₹2,500 at the top slab. The state's structure is progressive, with nine tiers above the nil threshold.
| Monthly Salary (₹) | PT (₹/month) |
|---|---|
| Up to 13,304 | Nil |
| 13,305 – 25,000 | 125 |
| 25,001 – 41,666 | 167 |
| Above 41,666 | 208 |
Odisha's structure mirrors Madhya Pradesh with slightly different thresholds. The annual maximum is ₹2,500.
| Monthly Salary (₹) | PT (₹/month) |
|---|---|
| Up to 15,000 | Nil |
| 15,001 – 20,000 | 150 |
| Above 20,000 | 200 |
Both states follow the same slab structure post-bifurcation. The annual maximum is ₹2,400. Self-employed professionals in Andhra Pradesh may qualify for a five-year exemption under specific conditions.
Not every Indian state imposes PT. The following states and union territories do not levy professional tax, which means employees working in these locations pay zero PT regardless of salary:
If your payroll state is on this list, your salary slip should not show a professional tax deduction. If it does, raise the issue with your employer's payroll team — a deduction in a non-PT state is an error that warrants a refund claim.
Professional tax paid during the year is fully deductible from salary income under Section 16(iii) of the Income Tax Act. This is one of the few deductions that survives under the new tax regime. While the standard deduction of ₹75,000 is the headline item under the new regime, the PT deduction continues to apply, reducing your taxable salary by the actual amount paid — up to the constitutional cap of ₹2,500.
The tax saving is modest but real. At the 30% slab, ₹2,500 of PT translates to ₹750 in tax saved (before cess). At the 20% slab, the saving is ₹500. The deduction is claimed automatically by your employer when computing TDS on salary, provided you have declared the PT amount and your Form 16 Part B reflects the deduction.
Employers hiring their first employee in a PT-levying state must register for a Professional Tax Registration Certificate (PTRC) within 30 days. Registration is done online through the state's commercial tax or GST portal. In Maharashtra, the portal is mahagst.gov.in. Once registered, the employer must deduct PT from salaries monthly and remit it to the state government by the prescribed due date — typically the last day of the following month for monthly filers, or quarterly for smaller employers.
Self-employed professionals need a Professional Tax Enrolment Certificate (PTEC) instead of a PTRC. The enrolment process is similar — online application, submission of professional credentials, and payment of the applicable fee. Several states offer a five-year exemption from PT for newly registered professionals, which means the enrolment certificate is issued but no tax is payable during the initial period.
Annual returns are mandatory in most states. The due date is usually 31 March or 30 April, depending on the state's fiscal calendar. Late filing or non-payment attracts interest at 1–1.5% per month and penalties ranging from 10% to 100% of the outstanding amount. In Maharashtra, the penalty can reach ₹5 per day of delay. Persistent non-compliance can result in prosecution and suspension of business licences.
A state-aware professional tax calculator takes three inputs: your state, your monthly gross salary, and — where applicable — your gender. The output is the monthly PT deduction, the annual liability, and the special month adjustment if your state uses one.
The logic behind the calculation is straightforward slab matching. The calculator holds a table of slab thresholds and deduction amounts for each state. It compares your salary to the thresholds, identifies the applicable slab, and returns the fixed amount. For half-yearly states like Tamil Nadu and Kerala, it converts the half-yearly liability into a monthly equivalent for easier salary planning, while noting that the actual deduction occurs twice a year.
For salaried employees, the calculator's output should match the PT line on your payslip. Discrepancies arise most often in three situations: a job change mid-year that shifts your payroll state, a salary increment that pushes you into a new slab, or an employer using outdated slab rates. Cross-checking the calculator result against your Form 16 Part B and your state's official portal is the most reliable way to catch errors.
Professional tax is calculated based on your gross monthly salary and the slab rates set by your state. The employer deducts the applicable PT amount each month and deposits it with the state government. For example, in Maharashtra, if your monthly salary is ₹50,000, you pay ₹200 per month, except in February when ₹300 is deducted to reach the annual cap of ₹2,500.
The constitutional ceiling under Article 276 is ₹2,500 per year per person. No state can collect more than this amount from a single individual in a financial year. Some states like Karnataka and West Bengal have a lower effective annual cap of ₹2,400.
Yes. Professional tax paid is fully deductible under Section 16(iii) of the Income Tax Act. This deduction is available under both the old and new tax regimes. The maximum deduction is ₹2,500 per year, which is the actual PT paid.
Delhi, Uttar Pradesh, Rajasthan, Haryana, Punjab, Uttarakhand, Himachal Pradesh, Jammu and Kashmir, Goa, and most Union Territories do not levy professional tax. Employees working in these locations pay zero PT regardless of their salary level.
Women in Maharashtra are exempt from professional tax up to a monthly salary of ₹25,000. Above ₹25,000, they pay the same rate as men — ₹200 per month, with ₹300 in February, totalling ₹2,500 annually.
Self-employed professionals need to obtain a Professional Tax Enrolment Certificate (PTEC) from the state's commercial tax or GST portal. Registration is typically required within 30 days of starting practice in a PT-levying state. Some states offer a five-year exemption for newly registered professionals.
Professional tax is generally non-refundable. However, if PT was deducted in a state that does not levy it, or if the deduction exceeded the constitutional cap, you can apply for a refund from the concerned state authority with supporting documents.
Late payment attracts interest at 1–1.5% per month on the outstanding amount in most states. Additional penalties range from 10% to 100% of the PT due, depending on the state and duration of default. In Maharashtra, the penalty can be up to ₹5 per day of delay.
In sum, a professional tax calculator transforms a payslip deduction that most employees overlook into a transparent, verifiable figure. Whether you are confirming the ₹200 monthly deduction in Maharashtra, checking whether Karnataka's ₹25,000 threshold exempts you, reconciling a half-yearly Tamil Nadu schedule, or claiming the Section 16(iii) deduction on your income tax return, the calculator removes the uncertainty. Use the professional tax calculator above, select your state, enter your gross salary, and treat the output as what it is: an accurate, state-specific calculation of a tax that every PT-levying state requires your employer to deduct — and that you are entitled to claim back on your income tax return.
