Sales Tax
Sales Tax Registration in KarachiGetting your STRN issued correctly the first time, whether you deal in goods or services.
Sales tax registration in Pakistan is not a single, uniform process. A trader in Jodia Bazaar selling goods needs an FBR sales tax registration number, while a service provider in Clifton or DHA running a consultancy, restaurant, or marketing agency needs to register with the Sindh Revenue Board instead. Many business owners come to us after applying on their own and getting stuck between these two regimes, or after their application was rejected for reasons that were never clearly explained on the portal.
We handle sales tax registration for manufacturers, importers, wholesalers, retailers, and service providers across Karachi, from SITE and Korangi industrial units to small retail outlets in Saddar. The process involves more than filling a form on IRIS or the SRB e-portal — it requires the right business activity codes, a verifiable business address, bank account details that match your NTN records, and, in most cases, biometric verification at a NADRA e-Sahulat centre.
Our role is to prepare the application correctly, respond to any queries FBR or SRB raise during processing, and make sure the registration reflects your actual business activity so that returns filed later are not flagged for mismatch. We also advise on whether your business needs FBR registration, SRB registration, or both, which is a common point of confusion for businesses that both sell goods and provide services.
Who this is for
Who needs this service
Any business manufacturing or importing taxable goods above the prescribed threshold must be registered for sales tax with FBR before it can legally invoice with sales tax or claim input tax adjustment.
Distributors and larger retail outlets, particularly those supplying registered persons, are usually required to register so their supply chain remains compliant and their buyers can claim input tax.
Consultants, agencies, contractors, restaurants, and similar service businesses operating in Karachi fall under Sindh Revenue Board jurisdiction and need an SRB registration, separate from any FBR sales tax number.
Companies bidding for government or corporate contracts are frequently asked to produce an active STRN as a prequalification requirement, even if their turnover would not otherwise compel registration.
A company adding a new business activity, opening a new branch, or converting from a sole proprietorship to a private limited company often needs a fresh or amended sales tax registration.

How it works
Our process, start to finish
Assessment of registration requirement
We review your business activity, turnover, and location to confirm whether you need FBR registration, SRB registration, or both, and identify the correct business activity classification.
Document preparation and portal filing
We prepare the application with your NTN, CNIC, business address, bank account, and utility details, and submit it through IRIS or the SRB e-portal as applicable.
Biometric and physical verification
We coordinate your biometric verification at a NADRA e-Sahulat centre and, where a physical or video verification of the business premises is required, guide you through what officers typically check.
STRN issuance and onboarding
Once your Sales Tax Registration Number is issued, we walk you through invoicing requirements, return filing deadlines, and record-keeping so you start on the right footing.
What we need from you
Documents typically required
- CNIC of the owner, partners, or directors
- NTN certificate of the business
- Proof of business address (rent agreement or ownership document)
- Recent electricity bill of the business premises
- Bank account maintenance certificate in the business name
- Partnership deed or Memorandum and Articles of Association, where applicable
- Letterhead and, for manufacturers, details of machinery or production capacity
- List of business activities and, where relevant, industry-specific licences
If a document is missing, tell us — in most matters we can work from what you have and obtain the rest on your behalf.
FBR versus SRB: getting the jurisdiction right
One of the most common mistakes we see in Karachi is a business assuming it only needs one type of sales tax registration when its activities actually straddle both regimes. A restaurant that also sells packaged food items, or an agency that sells goods alongside its services, may need to register with both FBR and SRB. Getting this wrong does not just cause paperwork headaches — it can mean invoices raised without the correct tax treatment, which creates problems for your customers trying to claim input tax.
We ask detailed questions about what you actually sell, to whom, and from where, before recommending a registration path. This matters more in Karachi than in some other cities because the city hosts such a wide mix of goods businesses in SITE and Korangi alongside a dense services sector in DHA, Clifton, and Saddar, all governed by different revenue authorities with separate portals and separate compliance calendars.
Timelines and what happens if registration is delayed
Sales tax registration is not instantaneous. Once an application is properly filed with complete documents, FBR or SRB will typically process it within a defined period, subject to biometric verification being completed and, in some cases, a site visit or video verification of the declared business premises. Delays usually stem from incomplete documentation, address verification issues, or a mismatch between declared business activity and what is found on inspection.
Operating without registration when you are legally required to register carries real exposure. Apart from the risk of penalties and default surcharge once the obligation is established, unregistered suppliers cannot issue tax invoices that let their buyers claim input tax, which puts you at a commercial disadvantage when dealing with registered businesses that prefer registered vendors.
Where applications go wrong, and how we work
The most frequent cause of rejection or delay is inconsistency: an address on the utility bill that does not match the rent agreement, a bank account not yet linked to the business NTN, or a business activity code that does not reflect what the company actually does. We check these details before filing rather than leaving them to be flagged by an officer weeks later.
We quote our fees upfront based on the complexity of your registration — a straightforward single-activity FBR registration is priced differently from a dual FBR-SRB registration involving multiple business activities — so there is no ambiguity once we begin work on your file.
Questions clients ask
Frequently asked questions
- Do I need FBR sales tax registration or SRB registration for my business in Karachi?
- It depends on what you sell. Goods generally fall under FBR sales tax, while services rendered in Sindh, such as consultancy, catering, or advertising, fall under SRB. Some businesses need both, and we assess this based on your actual business activity before recommending a path.
- How long does sales tax registration take once documents are ready?
- Once a complete application is filed and biometric verification is done, FBR or SRB typically processes it within a few weeks, though this can extend if a physical or video verification of the premises is required or if any document needs correction.
- Is biometric verification always required?
- Yes, for most individual and partner registrations, biometric verification at a NADRA e-Sahulat centre is a standard requirement before the STRN is issued, and we coordinate this step as part of the process.
- What happens if my registration application is rejected?
- Rejections are usually tied to a specific document mismatch or missing information rather than eligibility. We review the rejection reason, correct the underlying issue, and refile rather than resubmitting the same application repeatedly.
- Can a sole proprietorship register for sales tax, or is it only for companies?
- Sole proprietorships, partnerships, and companies can all register for sales tax, provided the relevant NTN and CNIC or registration documents are in order. Many of our clients are individual traders and small retailers rather than large corporations.
- Do I need a separate registration for each branch or business location?
- Not always a separate STRN, but additional branches or business locations generally need to be declared and added to your existing registration record with FBR or SRB, and we handle these amendments as your business grows.
