Presumptive / Turnover-Based Tax for Small Businesses in Nepal

A simplified flat-tax option for small shopkeepers and micro businesses — how it works, and when it makes sense.

Not every small business owner in Nepal wants to (or needs to) maintain detailed profit-and-loss accounts just to calculate income tax. For genuinely small operations, the tax system offers a simplified alternative known as presumptive or turnover-based tax, where a fixed amount is paid based on total turnover rather than calculating actual profit. This guide explains who qualifies, what the trade-offs are, and how to think about switching in or out of the scheme.

Who Qualifies (Turnover/Income Thresholds)

The presumptive tax scheme is designed specifically for small taxpayers whose annual turnover falls below a prescribed ceiling. Businesses operating above this ceiling are not eligible and must file under the regular income tax system with full accounts. Eligibility is generally based on:

• Total annual turnover staying within the prescribed limit for the scheme
• The nature of the business falling within categories permitted to use presumptive taxation (certain professional services and specific business types may be excluded regardless of turnover)
• The taxpayer being an individual or sole proprietorship in most cases, rather than a larger corporate structure

Flat Tax Slabs by Turnover Bracket

Rather than calculating actual profit, presumptive taxpayers pay a fixed amount that increases in slabs as turnover rises. As illustrated above, smaller businesses with turnover in the lowest bracket pay a smaller fixed amount, mid-range businesses fall into a higher fixed bracket, and businesses approaching the upper end of eligibility pay the highest flat amount permitted under the scheme. Once turnover exceeds the top threshold entirely, the business is no longer eligible and must transition to regular filing with full income and expense accounting.

What You Lose by Opting In (No Deductions, No Advance Tax Credit)

The simplicity of presumptive tax comes with real trade-offs that business owners should weigh carefully:

• No deductions: Business expenses — rent, wages, utilities, supplies — cannot be deducted against income, since the flat tax already assumes a standard treatment regardless of actual costs.
• No advance tax credit mechanism in the same way regular taxpayers reconcile installments against final liability, since the presumptive amount is essentially the full and final liability for the year.
• Limited ability to claim losses carried forward, which regular taxpayers with proper accounts may otherwise be able to use to offset future profits.
• Reduced credibility with banks or larger clients who may prefer working with businesses that maintain full, audited-style accounts.

For a business with genuinely low margins or higher documented expenses, staying under the regular filing system (even below the presumptive threshold) might actually result in lower tax than the flat presumptive amount — so the decision should be based on an honest comparison of numbers, not just convenience.

How to Switch From Presumptive to Regular Filing

A business can typically move from presumptive taxation to the regular income tax system either voluntarily (because it determines regular filing benefits it more) or because it has crossed the turnover threshold and is no longer eligible for the presumptive scheme. The switch generally involves notifying the tax office of the change, beginning to maintain proper books of account from the transition point forward, and filing under the standard annual return format from that year onward. Once a business exceeds the threshold, continuing to file as presumptive is not permitted and can trigger a reassessment.

Worked Example

Consider a small grocery shop with an annual turnover comfortably within the lowest presumptive bracket. Rather than tracking every purchase invoice, wage payment, and utility bill to calculate actual profit, the shop owner simply pays the fixed slab amount for that bracket at year-end. Compare this to a slightly larger hardware store whose turnover has grown into the middle bracket — it now pays the higher fixed amount corresponding to that slab, still without needing to prepare a full profit-and-loss statement. If that same hardware store's turnover eventually crosses the top threshold of the scheme, it must transition to regular filing, at which point maintaining proper purchase and sales records becomes mandatory rather than optional.

FAQ: Can a Shop Owner and a Consultant Use the Same Scheme?

Can a shop owner and an independent consultant both use the presumptive tax scheme?
Not necessarily. While the presumptive scheme is broadly aimed at small taxpayers, certain professional and consultancy-type services may be treated differently or excluded from eligibility, since these are commonly viewed as higher-margin services rather than simple trading businesses. A retail shop owner selling physical goods and an independent professional consultant may fall under different eligibility rules even at similar turnover levels, so it is important to confirm the specific eligibility criteria for your type of business activity rather than assuming eligibility based on turnover alone.

Is presumptive tax the same as VAT?
No. Presumptive tax is an income tax simplification scheme, while VAT is a separate consumption tax on goods and services. A business using presumptive income tax may still have separate obligations around VAT if it crosses the VAT threshold independently.

Can a presumptive taxpayer still get a Tax Clearance Certificate?
Generally yes, provided the fixed tax amount for the relevant period has been paid and there are no other outstanding dues. The TCC process still applies to presumptive taxpayers, just based on their simplified filing record rather than a detailed profit-and-loss return.
