Nepal follows a residence-based taxation system with separate provisions for residents and non-residents.

VAT (Value Added Tax) is an indirect tax applied on goods and services at each stage of production and distribution. In Nepal, VAT is levied at a standard rate of 13% (with certain exemptions). Registered businesses must file VAT returns periodically. It’s a crucial topic in BBS Taxation covering registration, input/output tax credit, and return filing.

Employment income tax is calculated using progressive slab rates for resident individuals. After deducting social security contribution, retirement fund, and standard allowance, taxable income is taxed from 1% to 36% (based on latest fiscal year). For BBS exams, numerical problems include salary, dearness allowance, festival expenses, and tax rebates.

Businesses with annual turnover exceeding NRs. 5 million (for goods) or NRs. 3 million (for services) must register for VAT. This is a core concept for BBS 3rd year taxation paper, including input tax credit mechanism and return filing within 25 days of each tax period.
