What Is Advance Tax Adjustment?

Definition of Advance Tax

Advance income tax means tax which is collected or paid in advance of the determination of the taxpayer’s tax liability for the current annual taxable income. It may be:

These amounts are combined in a yearly tax return. Taxable income is calculated, the final tax liability is determined and advance tax paid in the year is credited off the tax liability.

Let’s say the final tax liability of the freelancer is Rs350,000 and the clients have deducted Rs225,000 as tax which is eligible for adjustment. The freelancer should only be required to pay the remaining Rs125,000 with the completion of the adjustment of the tax return.

Why Advance Tax Is Collected

In the tax system, tax is collected at various stages of the transactions to enhance compliance and to ensure tax collection all year round. They are likely to be collected from:

What Is Adjustable Advance Tax Under Pakistani Law?

Adjustable advance tax is a sum which may be credited to the taxpayer’s taxable income of the tax year of the tax.

In general, the Income Tax Ordinance 2001 (section 168) considers eligible tax collected or deducted as tax paid by the person from whom the tax was collected or deducted. In computing the tax due for that taxable year, that person is credited with that amount of tax, except for the statutory exceptions.

This sets up the fundamental tax adjustment process:

  1. Calculate tax on annual taxable income.
  2. Identify eligible advance and withholding taxes.
  3. Subtract those credits from the calculated tax.
  4. Pay the remaining balance or report the resulting refund.

An advance tax credit is not the same as a personal tax credit for giving, like for donations or pension contributions. In this instance, the term “credit” means income taxes paid or collected in advance.

The final tax can normally not be altered the same way. Certain tax considered final under the relevant provisions are excluded from section 168, but there are special rules for making adjustments for excess amounts collected from persons not on the Active Taxpayers List.

Who Can Claim Advance Tax Adjustment?

1. Salaried Persons

A salaried taxpayer can modify any eligible transaction that is collected in the salary, like vehicle, electricity connection, property purchase, etc., or any banking transaction.

It is important to note that the employer’s salary certificate from the previous year is used to compare with the salary on IRIS.

2. Business Owners and Professionals

A business owner, such as a sole trader, doctor, lawyer, consultant, retail store or other business may have tax deducted from their sales, banking, services, contracts, rent, or utility bills.

They should compare to their accounts and gross receipts each certificate.

3. Freelancers

In Pakistan, freelancers may see a deduction in their taxes from either a Pakistani client, bank, payment service provider or corporate client. Just because it has been deducted doesn’t mean that it is automatically recovered. The freelancer is required to properly report income and set out that the withholding is “adjustable.

4. Companies and AOPs

Adjustments and advance payment of qualifying tax (QTC) may be made by a company or association of persons in the year. Quarterly advance-tax rules, formulas for calculating, estimates and credits for payments already made are included under Section 147.

5. Importers and Exporters

There are many possibilities for the taxation of import-stage tax in Section 148, which depend on the importer, goods and statutory category, among other factors. Special or final tax deductions for exports may also be available.

Even if there is a section, tax year and schedule that address the adjustability of the entire amount, importers and exporters should consult that section, year and schedule before determining the entire amount is adjustable.

Proper registration information is generally required prior to a taxpayer. NTN Registration Services in Lahore may be needed for first-time filers or for any business that is subject to sales tax, if they have not registered their business with the sales tax authorities, then it might be necessary to review the existing STRN and other registration documents with the tax authorities.

Which Advance Taxes Are Adjustable?

The legal treatment can vary by section, taxpayer type, transaction, and tax year.

Tax or transaction Usual treatment Important point
Tax paid under Section 147 Adjustable Credited against annual tax for the same year
Salary withholding Adjustable against salary tax Reconcile with employer certificate
Vehicle registration tax Commonly claimed as advance tax Confirm ownership, section, and tax year
Cash-withdrawal tax Expressly described as adjustable Currently applies under Section 231AB to specified withdrawals
Electricity tax Adjustable against tax liability Preserve the complete bill and consumer details
Telephone or internet tax Generally reported as collected tax Match the connection and taxpayer identity
Property purchase tax Advance tax Treatment should be checked under Section 236K
Property sale tax Advance tax, subject to applicable rules Capital-gain and non-ATL treatment may affect the computation
Client withholding on services Adjustable, minimum, or final depending on provision Do not assume all Section 153 tax is adjustable
Contract withholding Treatment varies Review the nature of the taxpayer and contract
Import-stage tax Adjustable, minimum, or final depending on category Check Section 148 and the First Schedule
Rental withholding Depends on the recipient and applicable provision Reconcile with declared rental income

Section 231AB specifically defines “qualifying tax on cash withdrawals” to be “adjustable. Section 235 provides that electricity-consumption tax under that provision is allowed to be adjusted against tax liability.
