By Zambian Economist Analyst
Most business planning in Zambia is reactive, and it does not have to be. A large share of the events that will change your costs this year are scheduled, published in advance, and ignored.
This is the calendar. Bookmark it, or put the dates in your phone now.
The four that matter most
| Date | Event | Why it matters |
|---|---|---|
| 30 July | ZamStats July inflation release | Sets the disinflation narrative going into the election |
| 13 August | General election, polls 06:00–18:00 | Six to ten weeks of altered operating conditions |
| 28–29 September | Bank of Zambia MPC meeting | First post-election policy signal; sets your borrowing cost |
| Late September | 2027 National Budget address | Tax measures that shape your entire 2027 cost base |
Monthly and recurring
Inflation — last Thursday of every month. The Zambia Statistics Agency publishes the Consumer Price Index, including headline, food and non-food inflation and provincial breakdowns. Remaining 2026 releases: 30 July, 27 August, 24 September, 29 October, 26 November, 31 December (confirm each with ZamStats).
Why you care: it is the single best read on where your input costs and your customers’ spending power are heading. See our inflation tracker.
Bank of Zambia Monetary Policy Committee — quarterly. 2026 meetings so far: 11–12 February (rate cut to 13.5%), 11–12 May (cut to 13.25%). Next: 28–29 September. A further meeting typically falls in November.
Why you care: it sets the benchmark from which your facilities are priced. See what the policy rate means for your loan.
Government securities auctions — regular. The Bank of Zambia runs Treasury bill and government bond auctions on a published schedule. Yields tell you what the government is paying for money, which is the floor under everything else.
Trade and GDP statistics — monthly and quarterly. ZamStats publishes monthly trade data and quarterly GDP. Q1 2026 real growth came in at 7.7% year on year, driven largely by agriculture.
Tax and compliance deadlines
Confirm all of these against the Zambia Revenue Authority’s published calendar, since dates shift when they fall on weekends and public holidays.
| Obligation | Typical deadline |
|---|---|
| VAT return and payment | 18th of the following month |
| PAYE | 10th of the following month |
| Withholding tax | 14th of the following month |
| Turnover tax | 14th of the following month |
| Provisional tax (quarterly) | 31 March, 30 June, 30 September, 31 December |
| Annual income tax return | 21 June following year end |
| NAPSA contributions | 10th of the following month |
Missing these costs penalties and interest, and — more expensively — a compliance record that follows you into tender evaluations.
Election period timeline
| Date | Event |
|---|---|
| 23 June | ECZ 50-day presidential campaign timetable commenced, running in ten five-day phases across all provinces |
| Late July – early August | Ballot verification and dispatch to districts, with parties and accredited observers invited to witness |
| 13 August | Polls open 06:00, close 18:00 |
| Following days | Counting, verification and declaration |
Practical planning for this period is in how Zambian businesses should plan for the election.
Budget season
The Minister of Finance and National Planning presents the national budget to the National Assembly in late September, pursuant to Article 202 of the Constitution. The last two were delivered on Friday 26 September 2025 (the 2026 budget) and Friday 27 September 2024.
The 2026 budget was K253.1 billion, or 27.4% of GDP — with K206.5 billion from domestic revenue, K12.1 billion in grants and K34.5 billion in borrowing.
After presentation, business of the House is suspended for twenty working days while committees conduct sector budget analysis. That window is when submissions from industry associations actually influence outcomes. If your sector has a position, prepare it in August, not October.
Agricultural and seasonal dates
Zambia’s economy still runs on the rains, so the agricultural year is an economic calendar in its own right.
| Period | What happens |
|---|---|
| November – March | Rainy season. Determines the following year’s food inflation and hydropower generation |
| April – June | Harvest |
| May onwards | Crop marketing season; the Food Reserve Agency sets its floor price (white maize was set at K347 this season) |
| June – October | Dry season. Peak construction and mining activity |
If you want an early read on next year’s inflation, watch the rainfall reports from December, not the CPI in June.
International dates that reach Zambia
- US Federal Reserve meetings — move the dollar, which moves copper, which moves the kwacha. See copper and the kwacha
- Chinese economic data releases — copper demand
- 1 January 2027 — the phased United States tariff on refined copper imports is scheduled to begin at 15%
- IMF and World Bank Annual Meetings, October — programme discussions and updated forecasts
How to actually use this
Three habits, each of which takes under ten minutes a month.
- Diary the four big dates now. MPC, inflation, budget, election.
- On the last Thursday of each month, read one number — non-food inflation. It tells you more about underlying cost pressure than the headline.
- Set a September reminder to review your 2027 pricing after the budget address, not in January when everyone else does.

The bottom line
Almost nothing in this calendar is a surprise. That is the point.
The businesses that get caught out by a rate decision, a tax change or an election slowdown are rarely caught out by the event. They are caught out by not having looked at the date.
