Small businesses in Pakistan pay income tax on net profit at progressive slab rates. Minimum tax under Section 113 (1.25% of gross turnover) applies even when profit is low. SMEs under Rs. 50M turnover get reduced corporate rate (20%). Monthly WHT on salaries, quarterly advance tax, and annual return are the three main compliance obligations.

Who Qualifies as a Small Business Under FBR?
FBR does not have a single universal SME definition, but several key thresholds determine which rules apply:
| Turnover Range | Tax Category | Applicable Rate |
|---|---|---|
| Under Rs. 4 million (sole proprietor, micro business) | Individual business income slab | 0–35% on net profit |
| Rs. 4M–100M (SECP-registered company) | SME reduced corporate rate | 20% on net profit (reduced from 29%) |
| Above Rs. 100M (company) | Normal corporate rate | 29% on net profit |
| Under Rs. 10M (retailer/service — sole prop) | Normal individual slab, no sales tax required | Individual slabs |
| Manufacturer (any size) | Normal income tax + mandatory STRN | Depends on structure |
SME reduced corporate rate (20%): Companies registered with SECP with annual gross sales between Rs. 4 million and Rs. 100 million can opt for the 20% reduced corporate rate instead of the normal 29%. To qualify, the company must have complete accounting records and file a regular return. This can be significantly cheaper than the 29% normal rate for SMEs.
Section 113 — Minimum Tax on Turnover
This is one of the most important provisions small business owners often miss. Under Section 113, if your income tax calculated on net profit is less than 1.25% of your gross turnover, you must pay the minimum tax at 1.25% of turnover instead.
This means even if you show low profit (or a loss) due to high expenses, FBR requires a minimum payment. Example:
| Scenario | Gross Turnover | Net Profit | Tax on Profit | Minimum Tax (1.25%) | Tax Payable |
|---|---|---|---|---|---|
| High margin business | Rs. 10,000,000 | Rs. 2,000,000 | Rs. 260,000 (est.) | Rs. 125,000 | Rs. 260,000 (profit tax wins) |
| Low margin / startup | Rs. 10,000,000 | Rs. 400,000 | Rs. 8,000 (2.5% slab) | Rs. 125,000 | Rs. 125,000 (minimum tax applies) |
| Loss year | Rs. 10,000,000 | - Rs. 500,000 | Rs. 0 (loss) | Rs. 125,000 | Rs. 125,000 (minimum tax applies) |
Minimum tax paid can be carried forward for up to 5 years and adjusted against future years' tax liability when profit tax exceeds minimum tax in those years. Certain sectors are exempt from minimum tax — including small traders registered under the Fixed Tax Scheme and exporters on whose income final WHT has been collected.
Business Expense Deductions for Small Businesses
Net taxable profit = gross revenue − allowable expenses. The following expenses are deductible for small businesses:
| Expense | Deductibility | Key Rule |
|---|---|---|
| Cost of goods sold (purchases) | 100% | Stock register and purchase invoices required |
| Staff salaries | 100% | WHT must be deducted and deposited if applicable |
| Shop/office rent | 100% | Rent agreement + proof of payment |
| Utilities (electricity, gas, water) | 100% for business premises | Bills in business name preferred |
| Machinery/equipment depreciation | 10–30% per year (Section 22) | Rate varies by asset class |
| Vehicle fuel (business use) | Business portion only | Log book recommended |
| Marketing and advertising | 100% | Invoices from media/printing required |
| Bank charges and interest | 100% | Bank statements as proof |
| Insurance premiums (business) | 100% | Policy documents required |
Quarterly Advance Tax for Small Businesses
If your previous year's income tax liability exceeded Rs. 100,000, you must pay advance tax in quarterly installments during the current year under Section 147. Miss a quarter and default surcharge accrues:
| Quarter | Period | Deadline | Amount |
|---|---|---|---|
| Q1 | Jul–Sep 2025 | Sep 25, 2025 | 25% of prior year tax |
| Q2 | Oct–Dec 2025 | Dec 25, 2025 | 25% of prior year tax |
| Q3 | Jan–Mar 2026 | Mar 25, 2026 | 25% of prior year tax |
| Q4 | Apr–Jun 2026 | Jun 15, 2026 | 25% of prior year tax |
If your business grew significantly, you may choose to pay more than the prior year amount to avoid underpayment surcharge. If business declined, you can apply to FBR RTO to reduce the advance installments — but you must apply before the quarterly deadline, not after.
WHT Obligations — Small Business as Employer
Once you hire employees or pay contractors, you become a withholding tax compliance with monthly obligations:
- Salary payments above Rs. 600,000/year per employee: Deduct monthly WHT under Section 149. Deposit by 7th of following month.
- Payments to contractors/service providers above Rs. 30,000/month: Deduct 7.5% WHT under Section 153. Deposit by 15th of following month.
- Monthly WHT statement (Section 165): File on IRIS by 15th of following month listing all WHT deductions.
Small businesses that ignore WHT obligations face double jeopardy. FBR can assess them for the WHT they failed to deduct (making the business pay the employee's tax out of pocket) AND impose a 100% penalty. This is one of the most common FBR audit findings against SMEs.
Common Small Business Tax Mistakes
| Mistake | Consequence | Fix |
|---|---|---|
| Mixing business and personal expenses | Disallowed deductions, wealth statement preparation issues | Separate bank accounts from day one |
| Not keeping stock register | Cannot justify cost of goods sold | Maintain purchase/sale register daily |
| Ignoring Section 113 minimum tax | FBR demand + surcharge | Calculate 1.25% × turnover vs profit tax each year |
| Paying salaries in cash without WHT records | FBR audit — business pays salary tax | Pay via bank transfer; deduct WHT |
| Not registering for STRN when turnover exceeds Rs. 10M | Penalty + back assessment of sales tax | Register promptly when threshold approached |
| Filing late or nil return when income exists | Penalty Rs. 1,000/month + non-filer rates | File by September 30 annually |
