Registering a sole proprietorship with the Federal Board of Revenue (FBR) is the first step toward legalizing a small business in Pakistan. This process involves obtaining a National Tax Number (NTN) and registering with tax authorities to ensure compliance. A sole proprietorship is the simplest form of business, where a single individual owns and operates the company. Registration allows business owners to open corporate bank accounts, apply for business loans, and participate in government tenders. It also helps in establishing credibility with customers and suppliers. The tax benefits associated with registration encourage business growth and legal compliance. Entrepreneurs can file tax returns online through the FBR portal, making the process convenient. Unlike larger business structures, sole proprietorships have minimal regulatory requirements. This makes it an ideal choice for freelancers, small traders, and startups. Overall, registering as a sole proprietor is a crucial step in establishing a legitimate business presence in Pakistan.
