Turnover Tax vs Income Tax — The Basics
Zambia offers small businesses a simplified tax option: turnover tax. Instead of calculating taxable profit (revenue minus expenses) and paying income tax on it, you simply pay 5% of your total revenue.
The choice matters because it directly affects how much tax you pay:
| Turnover Tax | Income Tax | |
|---|---|---|
| Rate | 5% of gross turnover | 30% of taxable profit (standard rate) |
| Threshold | K5,000,000 annual turnover or below | Any turnover level |
| Expense deductions | Not allowed | Fully allowed |
| VAT registration | Not required | Required if turnover exceeds K5,000,000 |
| Filing frequency | Quarterly (14th of following month) | Annual return + provisional quarterly payments |
| Best for | Low-expense, high-margin businesses | High-expense, lower-margin businesses |
When Turnover Tax Saves You Money
Turnover tax is cheaper when your profit margin is above approximately 17%. Here’s the math:
- Turnover tax: 5% of revenue
- Income tax: 30% of profit
- Break-even: 5% of revenue = 30% of profit → profit margin = 5/30 = 16.7%
If your profit margin exceeds 17%, turnover tax is cheaper. If it’s below 17%, income tax is cheaper (because you can deduct expenses).
Worked Example: High-Margin Business (Turnover Tax Wins)
A small retail shop with:
- Annual turnover: K600,000
- Annual expenses: K350,000
- Profit: K250,000 (42% margin)
| Regime | Calculation | Tax Payable |
|---|---|---|
| Turnover tax | K600,000 × 5% | K30,000 |
| Income tax | K250,000 × 30% | K75,000 |
Turnover tax saves K45,000 per year.
Worked Example: Low-Margin Business (Income Tax Wins)
A construction subcontractor with:
- Annual turnover: K700,000
- Annual expenses: K630,000
- Profit: K70,000 (10% margin)
| Regime | Calculation | Tax Payable |
|---|---|---|
| Turnover tax | K700,000 × 5% | K35,000 |
| Income tax | K70,000 × 30% | K21,000 |
Income tax saves K14,000 per year.
Worked Example: Loss-Making Business
A startup with:
- Annual turnover: K400,000
- Annual expenses: K520,000
- Loss: K120,000
| Regime | Calculation | Tax Payable |
|---|---|---|
| Turnover tax | K400,000 × 5% | K20,000 |
| Income tax | K0 (loss — no tax) | K0 |
With income tax, you pay nothing and carry the loss forward. With turnover tax, you still pay K20,000 even though you lost money. Turnover tax is disastrous for loss-making businesses.
Decision Table: Which Applies to You?
| Your Situation | Recommendation |
|---|---|
| Turnover below K5,000,000, profit margin above 20% | Turnover tax — simpler, cheaper |
| Turnover below K5,000,000, profit margin below 15% | Income tax — deductions save you money |
| Turnover below K5,000,000, inconsistent profitability | Income tax — protects you in loss-making years |
| Turnover above K5,000,000 | Income tax — mandatory (turnover tax not available) |
| Business earns consultancy or professional fees | Income tax — mandatory (excluded from turnover tax) |
| Startup with high initial costs | Income tax — deduct setup costs, carry losses forward |
Businesses Excluded from Turnover Tax
The following income types cannot use the turnover tax regime, regardless of turnover:
- Consultancy and professional fees — management consultants, lawyers, accountants, engineers
- Interest income — income from lending, deposits, or bonds
- Dividend income — income from shareholdings
- Rental income from commercial property — rental income has its own tax rules
- Mining income — subject to specific mining tax provisions
- Income from property dealing — property developers and dealers
If your business earns a mix of eligible and excluded income, the excluded portion must be taxed under income tax. This can create complex filing obligations — talk to a tax advisor.

When and How to Switch Regimes
Switching from Turnover Tax to Income Tax
You must switch if:
- Your annual turnover exceeds K5,000,000 at any point
You may switch voluntarily if:
- Your profit margins have dropped and income tax would be cheaper
- You want to claim business expense deductions
Process: Apply to ZRA for a change of tax type registration. The switch takes effect from the beginning of the next charge year.
Switching from Income Tax to Turnover Tax
You can switch to turnover tax if:
- Your annual turnover is K5,000,000 or below
- Your income is not from excluded categories (consultancy, interest, dividends, etc.)
Process: Apply to ZRA. You must have filed all outstanding income tax returns before the switch is processed.
2026 Changes
The 2026 budget introduced a significant change for late payment penalties:
- Old rate: 5% per month on outstanding tax
- New rate: 0.5% per month on outstanding tax
This applies to all tax types including turnover tax. While the penalty is now lower, interest at the Bank of Zambia lending rate still accrues on top. The penalty reduction is intended to encourage voluntary compliance and reduce the punitive burden on small businesses.

Frequently Asked Questions
What is the turnover tax rate in Zambia for 2026?
The turnover tax rate is 5% of gross turnover for businesses with annual turnover of K5,000,000 or below. This is a flat rate applied to total revenue — no deductions for expenses are allowed.
What is the turnover tax threshold in Zambia?
The threshold is K5,000,000 in annual turnover. Businesses below this threshold can elect to pay turnover tax instead of income tax. Businesses above the threshold must pay income tax (and register for VAT).
Can consultants pay turnover tax in Zambia?
No. Consultancy fees are specifically excluded from the turnover tax regime. If your business earns income from consultancy or professional advisory services, you must pay income tax regardless of your turnover level.
How do I switch from turnover tax to income tax?
You can switch by applying to ZRA for a change of tax type. If your turnover exceeds K5,000,000, the switch is mandatory. Allow at least 30 days for ZRA to process the change. You will begin filing income tax returns from the next tax period.
Is turnover tax filed monthly or annually?
Turnover tax is filed and paid quarterly. Returns are due by the 14th of the month following the end of each quarter. For example, Q1 (January–March) is due by 14 April.
Can I claim expenses under turnover tax?
No. Turnover tax is calculated on gross revenue, not profit. You cannot deduct salaries, rent, materials, or any other business expenses. This is the main disadvantage for high-expense businesses.
