Turnover Tax in Zambia (2026): Who Pays, How to Calculate It, and How to File With ZRA
The tax most Zambian small businesses actually pay
If you run a shop in Kabwata, resell hardware in Kitwe, cut hair in Chipata or farm outside Mkushi, the tax that applies to you is almost certainly not company income tax. It is turnover tax, and it works on a completely different principle: it is charged on what you sell, not on what you earn after costs.
The Zambia Revenue Authority defines turnover as all earnings received from business activities - sales, revenue, income, takings and proceeds. There is no deduction for stock, rent, wages, transport or interest. That makes it simple to compute and, for some businesses, considerably more expensive than it looks.
This guide is built from ZRA's own June 2026 turnover tax booklet and its published due-date and penalty pages. Where those two ZRA sources disagree with each other, that is said plainly rather than papered over.
Who has to register for turnover tax
ZRA's rule is a ceiling, not a choice. Businesses with annual sales of K5,000,000 or less are required to register for turnover tax. Businesses with annual sales above K5,000,000 must register for income tax instead.
The threshold moved from K800,000 to K5,000,000 with effect from 1 January 2025. Any guide, template or accountant's note still quoting K800,000 as the general turnover tax ceiling is out of date - the K800,000 figure survives only for artisanal and small-scale mining, which has its own separate threshold.
Who is locked out of turnover tax
Being small is not enough on its own. ZRA lists six categories that cannot register for turnover tax:
- Any person whose annual turnover exceeds K5,000,000.
- Partnerships, regardless of turnover. This is the one that surprises people most often. Two friends trading together as a registered partnership are outside turnover tax entirely, even on K200,000 of sales.
- Individuals or partnerships operating public service vehicles carrying fewer than 50 passengers. Minibus and taxi operators fall under presumptive tax instead.
- Businesses in mining operations under the Mines and Minerals Development Act, except artisanal and small-scale miners.
- Income already subject to withholding tax that is treated as final tax - bank interest earned by individuals, dividends, interest on government bonds, treasury bill interest for charitable and exempt persons, payments to non-resident contractors, public entertainment fees paid to non-residents and royalties paid to non-residents.
- Management and consultancy services, excluded from turnover tax by the Income Tax (Amendment) Act No. 1 of 2005.
That last exclusion matters to a growing share of Zambians. If you invoice for advisory, IT consulting, training design or management services, you are not a turnover-tax business no matter how modest your billings. Farming, by contrast, is inside: ZRA states that farming businesses with annual turnover below K5,000,000 are taxed under the turnover tax regime at 5%.
The rate and the 0% band
ZRA publishes turnover tax as a two-line table:
| Turnover per month | Annual turnover | Rate |
|---|---|---|
| K2,500 or less | K30,000 or less | 0% |
| Above K2,500 | Above K30,000 up to K5,000,000 | 5% |
So a genuinely tiny trader - under K2,500 of sales in a month - has a return to file but nothing to pay.
ZRA's worked example, and the contradiction inside it
The booklet gives this example. AZ Limited runs a retail business. In January 2026 it makes total sales of K6,000. ZRA computes:
- K6,000 minus K2,500 equals K3,500
- K3,500 times 5% equals K175
Read that carefully, because immediately underneath, the same page adds a note that businesses with annual turnover above K30,000 pay turnover tax at 5% on their total turnover. On the same K6,000 of sales that second reading gives K300, not K175.
Both statements are ZRA's. We are not going to invent a resolution. What we can say is this: the worked example is the more specific of the two and it deducts the K2,500, and the figure that actually binds you is the one the return computes when you complete it on TaxOnline. File what the return calculates, keep the acknowledgement, and if the two readings would change your liability materially, put the question to ZRA on 4111 or advice@zra.org.zm in writing before the 14th. A written ZRA answer is worth more than any website's arithmetic, including ours.
For planning purposes our worked figures below use ZRA's own example method - deduct the K2,500 monthly band, then apply 5%.
The trap: turnover tax ignores your margin
Because there is no deduction for costs, two businesses with identical sales and wildly different profits pay exactly the same tax. Take two traders, each turning over K400,000 in a year:
Trader A sells services with low input costs. Costs K120,000, profit K280,000. Turnover tax at 5% on turnover above the K30,000 exempt band is K18,500. That is 6.6% of profit.
Trader B resells groceries and airtime on thin markups. Costs K360,000, profit K40,000. Turnover tax is the identical K18,500 - now 46% of profit.
Trader B is not doing anything wrong. This is how a turnover tax behaves by design. The practical response is not to hide sales, which is how businesses end up in penalty territory; it is to price with the 5% built in, to know your true gross margin on every line, and to think hard before chasing high-turnover, low-margin volume. If you are borrowing to fund that volume, run the repayment against the margin first with our personal loan calculator, or compare terms on business loans before you commit.
Registering: the 30-day clock
A person starting a business must notify the Commissioner General within 30 days of commencing business, and register for:
- A Taxpayer Identification Number (TPIN), the ten-digit number that is your login for every ZRA service, and
- the appropriate tax type - here, turnover tax.
If your company is coming through PACRA, the incorporation route and the tax registration route connect, but confirming the tax-type registration is still your responsibility. Our walkthrough on how to register a business in Zambia covers the PACRA side; this page covers what happens after.
Registering does not by itself create a liability. It creates a filing obligation - which is why nil returns exist, and why not filing is far more expensive than filing a zero.
Filing: the 14th, and three ways to do it
Turnover tax returns must be submitted electronically on or before the 14th day of the month following the month in which the sales occurred. ZRA's own example: sales made in January, return due by 14 February. Payment follows the same date - turnover tax must be paid by the 14th day of the month following the month in which the sales were made.
Note that this is monthly, not quarterly. Some guides describe turnover tax as a quarterly obligation; ZRA's published due-date page and its 2026 booklet both say the 14th of the subsequent month, every month.
You can file and pay through three channels:
- TaxOnline, the ZRA web portal
- TaxOnApp, the ZRA mobile app
- TaxOnPhone on
*858#, which matters if you are trading somewhere with a weak data signal
Whichever you use, your registered phone number and email must be current on your ZRA profile - one-time passwords and acknowledgements go there, and a dead number is the most common reason a trader cannot file at four in the afternoon on the 14th.
Where turnover tax sits in the wider ZRA calendar
If you also have staff or other registrations, the dates are not the same:
| Obligation | ZRA due date |
|---|---|
| PAYE (monthly return ITF/P16) | 10th of the following month |
| Skills Development Levy | 10th of the following month |
| Mobile money transaction levy | 10th of every month |
| Turnover tax | 14th of the following month |
| Withholding tax | 14th of every month |
| VAT (electronic submissions) | 18th of every month |
| Annual income tax return and balance | 21 June |
If you employ anyone, the PAYE side has its own rules and its own arithmetic - our guide to understanding your payslip and the income tax calculator set out the 2026 bands, and remember that in Zambia NAPSA and NHIMA do not reduce the PAYE base.
What being late costs
Per ZRA's 2026 booklet:
- Late submission of a return: 250 penalty units, currently K100, per month or part of a month.
- Late payment: a penalty of 0.5% per month (or part of a month) on the outstanding amount, plus interest at the Bank of Zambia Discount Rate plus 2%. This applies to both individuals and companies.
Two honest caveats. First, ZRA's older penalties web page still shows 250 penalty units as K75 and the turnover-tax late-payment penalty as a flat 5% of the unpaid amount. The June 2026 booklet is the newer document and is what we publish, but if you are computing an exact historic exposure, confirm which figures applied to your period on 4111. Second, the interest leg moves with Bank of Zambia policy, so it is not a fixed number you can memorise.
The structural point is unchanged either way: the penalty for not filing runs every month whether or not you owed anything. A nil return costs nothing. Silence compounds.
Keep six years of records
ZRA requires business records to be kept for at least six years, and lists sales records, invoices and receipts, bank statements and accounting records. These may be required by ZRA to verify your tax obligations.
Six years is longer than most Zambian small businesses keep anything. The cheapest fix is structural, not clerical: run business money through a business account rather than your personal mobile wallet, so the bank statement itself becomes the record. Our bank account comparison sets out what the accounts actually charge, and separating business float from household money also makes the savings calculator meaningful when you start putting the tax aside monthly rather than finding it on the 13th.
Crossing K5,000,000
If you expect turnover to exceed K5,000,000 during the year, you must notify the Commissioner General. What happens next is more forgiving than people fear:
- You continue paying turnover tax until the end of that charge year, and
- you move to income tax in the following charge year.
The same applies in reverse: a taxpayer moving from income tax to turnover tax can only change at the beginning of a charge year. No changes are allowed during the charge year. So growing past the ceiling in August does not retroactively convert your year - but failing to notify does put you offside.
When you do cross, the regime is different in kind: income tax is charged on profit, with company income tax at 30% standard, and VAT registration brings its own 16% obligations and the 18th-of-the-month return. Our VAT calculator handles that arithmetic, and the Zambia tax guide covers the wider picture.
Closing the business
If a business closes - business failure, bankruptcy or winding up - the taxpayer must inform the Commissioner General immediately. Deregistration applications go through TaxOnline under the Applications module, together with a PACRA cessation certificate.
Businesses that simply stop trading without deregistering keep accruing late-filing penalties on returns nobody is filing. If you have stopped, close it properly.
Frequently asked questions
Do I have to file if I made no sales this month? Yes. Registration creates a filing obligation independent of liability. File a nil return. The late-submission penalty runs per month or part of a month whether or not tax was due.
Is turnover tax monthly or quarterly? Monthly. ZRA's 2026 booklet and its published payment due dates both specify the 14th day of the month following the month in which the sales were made. Sources describing it as quarterly are describing provisional income tax, which is a different regime.
I am a consultant with small billings. Can I use turnover tax to keep things simple? No. Management and consultancy services are excluded from turnover tax under the Income Tax (Amendment) Act No. 1 of 2005, whatever your turnover. You register for income tax instead.
My friend and I trade together. Does our partnership qualify? No. Partnerships are excluded regardless of turnover. If you are trading as a registered partnership you are outside the turnover tax regime entirely.
Does the K30,000 exempt band apply once a year or every month? ZRA expresses it both ways - K2,500 per month, K30,000 per year - and its own worked example applies the K2,500 monthly. What binds you is the figure the return computes. If the difference is material to you, get ZRA's answer in writing on 4111 or advice@zra.org.zm before the 14th.
What if I cannot pay by the 14th but I can file? File anyway. The two penalties are separate: one for the late return, one for the late payment. Filing on time removes the first of them and leaves you dealing only with the payment penalty and the interest.
