Advance Tax Under Section 147 Explained

Advance tax under section 147 of the Income Tax Ordinance is the mechanism by which businesses and certain individuals pay their income tax in quarterly instalments during the year, rather than in a lump sum after the year ends. It is separate from withholding tax deducted by others on your receipts, although the two interact when computing what is owed. Understanding the rules helps avoid both default surcharge and unnecessary cash flow strain.

The obligation applies to companies, associations of persons and individuals whose income in the latest assessed year exceeded a threshold set in the Ordinance. Salaried individuals whose only income is salary are excluded because their employer withholds tax monthly. Individuals with business income, rental income or other sources above the threshold are covered. Newly established companies estimate their liability from the outset even without a prior assessed year.

The basic formula for each quarter takes the tax assessed for the latest tax year, multiplies it by the turnover of the current quarter, divides by the turnover of the latest assessed year, and then subtracts tax already withheld or collected from you during the quarter. The result is the instalment payable. In effect, the law assumes your effective tax rate is unchanged and scales it to your current level of activity.

Instalment due dates fall on the twenty-fifth of September, December and March, and the fifteenth of June for individuals and associations of persons. Companies follow a similar schedule aligned to their financial year. Payment is made through the FBR payment system by generating a payment slip identification number and paying at a bank or through online banking.

Taxpayers are permitted to estimate their own liability for the year if they believe it will differ from the figure the formula produces. If you expect lower profits, you may file an estimate before the second instalment and pay on that basis. If you expect higher profits, you are required to file a revised estimate and pay the higher amount, and the law specifically requires that at least ninety percent of the final liability be paid by the last instalment.

The consequence of underpayment is default surcharge, calculated at a prescribed rate on the shortfall from the date the instalment was due until the date the tax is actually paid. Where a taxpayer files a lower estimate that turns out to be significantly below the actual liability, the FBR can also impose penalties. This is why many businesses adopt a cautious approach and estimate slightly above their expected outcome.

Advance tax paid is fully adjustable. When you file your annual return, the instalments are credited against the tax computed on your actual income. If you paid more than you owed, the excess becomes a refund claim. If you paid less, the balance is due with the return. Keep every payment challan, since IRIS will need the CPR numbers to record the credit.

Interaction with minimum tax and turnover tax matters for businesses with low margins. If your final liability is determined under the minimum tax provisions rather than on normal profits, your advance tax instalments should reflect that expected outcome. Businesses that ignore this often find they have paid advance tax on a profit basis while the minimum tax turns out to be higher, leaving a shortfall and surcharge.

Good practice is to review the position at the end of each quarter with your accountant. Compare turnover to date with the prior year, check how much withholding has already been suffered on your receipts, and decide whether the formula-based instalment or a revised estimate better reflects reality. Documented estimates protect you if the FBR later questions why a particular instalment was paid at a particular amount.

Advance tax is often seen as a nuisance, but it prevents the shock of a large single payment and spreads the burden across the year in line with earnings. Managed carefully, it is simply part of the normal rhythm of running a compliant business in Pakistan.
