Anyone who has stared at a monthly electricity bill wondering why the total is so much higher than expected already knows the frustration. Between GST, fuel price adjustments, and withholding tax, working out the real deduction by hand is tedious — which is exactly why TaxCalculators.pk built its Electricity Consumption Tax Calculator. This free tool applies FBR’s Section 235 rates instantly to any commercial, industrial, or domestic bill, showing exactly how much tax gets deducted before the printed bill even arrives. It’s fully updated for Tax Year 2026-27, and this guide walks through every rate, rule, and worked example behind the numbers.
Quick Answer: Under FBR Section 235, commercial and industrial electricity bills are taxed at 10% (bills of PKR 501–20,000) or PKR 1,950 plus 12% (commercial) / 5% (industrial) on anything above PKR 20,000. Non-ATL domestic bills are taxed at 7.5% only when the bill exceeds PKR 25,000; bills up to that amount are exempt. Use the electricity tax calculator above to get your exact figure in seconds.

What Is the Electricity Consumption Tax Calculator?
The Electricity Consumption Tax Calculator is a free online tool that estimates the withholding tax deducted from an electricity bill under Section 235 of the Income Tax Ordinance, 2001. Rather than digging through FBR notifications or doing slab math by hand, a user simply picks their consumer type and enters the gross bill amount — the calculator does the rest.
Specifically, this electricity tax calculator handles:
- Commercial electricity tax on shop, office, and business connections
- Industrial electricity tax on factory and manufacturing connections
- Domestic electricity tax for non-ATL residential consumers
- Advance tax adjustments that later show up in the annual income tax return
Because it's built around the official FBR withholding tax card, the electricity bill calculator stays accurate even as slabs are reviewed each fiscal year.
Understanding FBR Section 235 (Electricity Tax Explained)
Section 235 of the Income Tax Ordinance, 2001 governs advance tax collection on electricity consumption in Pakistan. It's a withholding tax on electricity bill amounts — meaning the relevant DISCO (electricity distribution company) deducts it automatically at source, before the bill is even printed.
The FBR electricity tax under this section applies mainly to three groups:
- Commercial consumers — shops, offices, retail outlets
- Industrial consumers — factories and production units
- Non-ATL domestic consumers — residential users not listed on FBR's Active Taxpayer List (ATL)
The Federal Board of Revenue uses this advance tax on electricity bill collection as a compliance mechanism — it's one of the simplest ways to bring non-filers into the documented tax net, since almost every household and business pays an electricity bill regardless of whether they file a tax return.
Updated Section 235 Tax Slabs for Tax Year 2026-27
The table below reflects the confirmed Section 235 electricity tax slabs applicable for Tax Year 2026-27 under the Finance Act 2026. The tax on commercial electricity bill amounts and industrial connections shares the same bracket structure, but the percentage charged above PKR 20,000 differs between the two — a distinction covered in detail below.
Commercial & Industrial Electricity Tax Rates
| Gross Monthly Bill | Commercial Tax | Industrial Tax |
|---|---|---|
| Up to PKR 500 | Exempt (0%) | Exempt (0%) |
| PKR 501 – 20,000 | 10% of bill | 10% of bill |
| Above PKR 20,000 | PKR 1,950 + 12% of excess | PKR 1,950 + 5% of excess |
Domestic (Non-ATL) Electricity Tax Rates
| Gross Monthly Bill | Tax Rate |
|---|---|
| Up to PKR 25,000 | Exempt (0%) |
| Exceeds PKR 25,000 | 7.5% of full bill |
ATL vs Non-ATL Electricity Tax — What's the Difference?
This is one of the most commonly misunderstood parts of Section 235. The domestic slab only applies to non-ATL households. A domestic connection registered under a taxpayer who is active on the ATL is not subject to this particular withholding clause, no matter how high the bill is. In short, the difference between filer and non-filer electricity tax comes down entirely to ATL status — the rate itself never changes, only whether it applies at all.
| Filer Status | Domestic Bill Below PKR 25,000 | Domestic Bill Above PKR 25,000 |
|---|---|---|
| ATL / Active Filer | No Section 235 domestic tax | No Section 235 domestic tax |
| Non-ATL / Non-Filer | Exempt (0%) | 7.5% of full bill |
Commercial and industrial slabs, by contrast, apply equally regardless of ATL status — the filer/non-filer distinction only changes the outcome for domestic consumers.
Why "Exceeds," Not "At Least"
A bill of exactly PKR 25,000 stays exempt — the 7.5% domestic rate only kicks in once the bill genuinely exceeds that figure.
Filer Advantage
Getting on the Active Taxpayer List removes the domestic electricity tax exposure entirely — one of the simplest ATL benefits available to households.
How Electricity Bill Tax Is Calculated (Step-by-Step)
Working out how much tax is deducted from an electricity bill takes just a few steps once the right slab is identified.
Identify Consumer Type
Confirm whether the connection is commercial, industrial, or domestic — the rate structure is different for each.
Check the Gross Bill
Note the total bill amount before tax — Section 235 tax is calculated on the bill value, not on units (kWh) consumed.
Apply the Correct Slab
Match the bill amount to the applicable commercial, industrial, or domestic slab from the tables above.
Confirm ATL Status
For domestic bills only, confirm whether the consumer is on the Active Taxpayer List, since ATL status removes the domestic tax entirely.

Worked Examples — Electricity Tax Calculator in Action
Numbers make this easier to picture. Here's how the electricity bill tax calculator applies each slab in practice:
| Consumer Type | Bill Amount | Calculation | Tax Payable |
|---|---|---|---|
| Commercial | PKR 10,000 | 10% × 10,000 | PKR 1,000 |
| Commercial | PKR 30,000 | 1,950 + 12% × 10,000 | PKR 3,150 |
| Commercial | PKR 50,000 | 1,950 + 12% × 30,000 | PKR 5,550 |
| Industrial | PKR 30,000 | 1,950 + 5% × 10,000 | PKR 2,450 |
| Industrial | PKR 50,000 | 1,950 + 5% × 30,000 | PKR 3,450 |
| Domestic (Non-ATL) | PKR 20,000 | Below threshold | PKR 0 |
| Domestic (Non-ATL) | PKR 28,000 | 7.5% × 28,000 | PKR 2,100 |
| Domestic (Non-ATL) | PKR 40,000 | 7.5% × 40,000 | PKR 3,000 |
Notice how a commercial or industrial electricity bill above 20,000 always carries the PKR 1,950 base amount first, before the percentage on the excess is added — a detail that's easy to miss when calculating manually.
Beyond Tax: Understanding the Rest of the Electricity Bill
Section 235 tax is only one line item on a Pakistani electricity bill. To fully understand the total amount owed, it helps to know what else is added:
- GST on electricity bill: Sales tax is applied to the energy charges portion of the bill, separate from the Section 235 withholding tax.
- Fuel Price Adjustment (FPA): A monthly adjustment reflecting the changing cost of fuel used to generate electricity, notified periodically by NEPRA. This FPA calculation electricity component can shift the total bill up or down from one month to the next, independent of the tax slab.
- Quarterly tariff adjustment: A periodic revision to the base tariff, also determined by the National Electric Power Regulatory Authority (NEPRA).
- Electricity duty: A separate provincial levy charged on the energy portion of the bill.
- PTV / TV license fee: A small fixed fee bundled into most residential bills.
- Neelum Jhelum (NJ) Surcharge: A surcharge that funds the Neelum-Jhelum hydropower project, applied to most consumer categories.
How Is Electricity Bill Calculated in Pakistan?
Outside of Section 235, the base bill itself is unit-based. An electricity unit rate calculator works by multiplying units consumed (kWh) by the applicable per-unit slab rate, then layering GST, FPA, duty, and fixed charges on top. Calculating an electricity bill from meter reading simply means subtracting last month's reading from this month's, applying that unit figure to the correct slab, and adding the standard charges — a job suited to a dedicated bijli bill calculator or electricity bill estimator, rather than this withholding-tax-focused tool.
3-Phase, Peak Hours & Time-of-Use Connections
Larger commercial and industrial connections often run on three-phase power with higher fixed charges. Some also use Time-of-Use (ToU) meters, where a peak hours electricity calculator becomes useful, since peak-hour units (typically evenings) are billed at a noticeably higher rate than off-peak units. None of this changes the Section 235 withholding tax calculation itself — that's still based purely on the gross bill amount — but it does explain why two commercial connections with similar usage can end up with very different bill totals before tax is even applied. A 3-phase electricity bill calculator and a time-of-use tariff calculator are both useful companions for businesses trying to understand that base amount.
For a full breakdown of per-unit tariffs and slab rates by units consumed, NEPRA and the National Energy Efficiency & Conservation Authority (NEECA) both publish official reference tools that complement this electricity consumption tax calculator. This page focuses specifically on the FBR withholding tax portion — the slab rate calculator Pakistan users need for the tax deduction, not the full bill estimate.
DISCO-Wise Electricity Tax Applicability Across Pakistan
Section 235 rates are set federally and apply the same way nationwide, but it helps to know which distribution company (DISCO) serves each region:
| Region | Distribution Companies (DISCOs) |
|---|---|
| Punjab | LESCO, GEPCO, FESCO, MEPCO |
| Sindh | HESCO, SEPCO, K-Electric (Karachi) |
| Khyber Pakhtunkhwa | PESCO, TESCO |
| Balochistan | QESCO |
| Islamabad Capital Territory | IESCO |
Regardless of which DISCO issues the bill — whether it's LESCO in Lahore, GEPCO in Gujranwala, or K-Electric in Karachi — the Section 235 electricity tax slabs are identical. Only the fixed charges and meter rent portions of the bill vary slightly by DISCO; the withholding tax calculation this tool performs stays the same across the country.
Advance Tax Treatment — Companies vs Other Taxpayers
How the Section 235 deduction is treated at tax-return time depends on who's paying it:
| Taxpayer Category | Treatment |
|---|---|
| Companies | Always treated as adjustable advance tax, regardless of the bill amount |
| Other taxpayers — annual bill up to PKR 360,000 | Treated as minimum tax |
| Other taxpayers — annual bill above PKR 360,000 | Treated as adjustable advance tax |
This distinction matters at filing time — tax treated as "adjustable" can be offset against the final liability shown on the annual return, while "minimum tax" generally cannot be reduced below what's already been withheld.
Electricity Tax Calculator vs Bill Calculator — What's the Difference?
Many people searching for an electricity bill calculator Pakistan actually want one of two different tools, and it's worth knowing which is which:
| Tool Type | What It Estimates | Best For |
|---|---|---|
| Electricity Tax (WHT) Calculator | Section 235 withholding tax on the bill amount | Filers checking FBR deductions, adjusting advance tax on their return |
| Electricity Bill / Unit Calculator | Full bill from units consumed — slab tariff, FPA, GST, fixed charges | Households estimating next month's total bill before it arrives |
TaxCalculators.pk's Electricity Consumption Tax Calculator is built specifically for the first case — the FBR withholding tax angle — since that's the part most bill-estimator tools skip entirely.

Common Mistakes to Avoid
- Assuming units consumed (kWh) affect the Section 235 rate — the tax is based on the bill amount, not units
- Confusing the commercial 12% rate with the industrial 5% rate above PKR 20,000
- Forgetting the PKR 1,950 fixed base amount before adding the percentage on the excess
- Believing ATL domestic users are also subject to the 7.5% domestic tax — they are not
- Mixing up "exceeds PKR 25,000" with "PKR 25,000 or more" — the threshold is exclusive, not inclusive
Tax Year 2025-26 vs 2026-27 — What Changed?
The underlying Section 235 slabs carried forward unchanged into Tax Year 2026-27 — commercial and industrial rates, and the 7.5% non-ATL domestic rate, remain the same as previously published. The one refinement for Tax Year 2026-27 is a clarification on the domestic threshold wording: the tax applies when a bill exceeds PKR 25,000, rather than the earlier "PKR 25,000 or more" phrasing. In practice this only changes the outcome for a bill sitting at exactly PKR 25,000, which now stays exempt.
Conclusion
Electricity tax in Pakistan doesn't have to be confusing once Section 235 is broken down slab by slab. Whether it's a shop owner checking a commercial bill, a factory confirming its industrial rate, or a household finding out whether ATL registration would remove its domestic tax exposure, the Electricity Consumption Tax Calculator turns a multi-step manual calculation into a single instant result — fully updated for Tax Year 2026-27.
Frequently Asked Questions
Only to non-ATL domestic consumers, and only when the monthly bill exceeds PKR 25,000. Domestic consumers who are active filers on the ATL are not subject to this particular tax.
Commercial bills up to PKR 500 are exempt, bills from PKR 501–20,000 are taxed at 10%, and bills above PKR 20,000 are taxed at PKR 1,950 plus 12% of the amount exceeding PKR 20,000.
For a commercial connection, the tax is PKR 1,950 + 12% of PKR 10,000 (the amount over PKR 20,000), totaling PKR 3,150. For an industrial connection, it's PKR 1,950 + 5% of PKR 10,000, totaling PKR 2,450.
Yes, for companies and for other taxpayers whose annual electricity bill exceeds PKR 360,000, the tax withheld is treated as adjustable advance tax and appears in the withholding tax statement. For other taxpayers with lower annual bills, it is treated as minimum tax.
Section 235 of the Income Tax Ordinance, 2001 is the provision under which advance tax is collected on electricity bills at the point of billing, primarily targeting commercial, industrial, and non-ATL domestic consumers.
General Sales Tax is applied separately from Section 235 withholding tax, calculated on the energy charges portion of the bill rather than the final payable amount. It is a distinct line item from the advance tax this calculator estimates.
For a non-ATL domestic connection, a bill that exceeds PKR 25,000 becomes subject to a 7.5% withholding tax on the full bill amount. Getting onto the Active Taxpayer List removes this exposure entirely.
