Rates, thresholds and deadlines change. The figures on this page reflect the rules Bumara applies today and are given as a guide. The regulator’s current published position always governs. Bumara applies the rate in force when your filing is calculated — always check the figures shown on your actual filing rather than relying on this page, and take professional advice on how the rules apply to your business.
The Zambia Revenue Authority handles your taxes. It is the regulator with the most frequent obligations — most are monthly — and the one where falling behind grows most expensive, because interest and penalties accrue.

What you handle here

PAYE

Monthly tax deducted from your employees’ pay and remitted to ZRA.

Turnover tax

A simplified monthly regime for smaller businesses — a flat rate on gross turnover.

Withholding tax

Tax you deduct when paying for certain services and remit on the supplier’s behalf.

Smart Invoice

Transmitting your sales invoices to ZRA as you issue them.

Your TPIN

Your Taxpayer Identification Number is ten characters and is required for almost everything: invoicing, every return, employee records, and most other regulators’ processes. If you do not have one, request it as a service — TPIN application — from the ZRA service catalogue. You will generally need your PACRA certificate first. Enter your TPIN in Set up your business. Bumara checks the format but cannot verify it against ZRA, so check it against your certificate character by character.

Connecting ZRA

1

Open the ZRA workspace and choose Connect

From the sidebar under Regulators.
2

Confirm your TPIN

Taken from your organisation settings.

Select your tax types

This is the important step. Tick only what you are actually registered for:

Connect

Bumara creates one obligation per tax type you selected, and generates the current period’s filing for each.
Turnover tax and standard income tax are alternatives, not additions. If you are on turnover tax you are not also filing standard income tax returns. Ticking both creates obligations you do not owe and will spend months filing nil returns against.

Due dates

How your other Bumara data feeds ZRA returns

This is where most of the time saving is: You review and confirm the figures rather than assembling them.

Nil returns

If you had no activity in a month you still file — a nil return, with a reason: A nil return has a much shorter checklist and often becomes ready immediately.
An unfiled nil return is still an unfiled return, and attracts the same late-filing penalty as one with figures. “We had no activity” is not a reason to skip the filing.

Tax clearance certificate

A valid tax clearance certificate is required for tenders, many contracts, and some licences. ZRA will not issue one while you have outstanding returns or unpaid tax. Request one from the ZRA service catalogue. If it is refused, a compliance health check will tell you exactly what is blocking it.

If you have fallen behind

ZRA arrears grow. Interest accrues on unpaid tax, penalties are assessed for late filing, and persistent non-compliance leads to audit flags and enforcement action. Run a compliance health check before doing anything else. It establishes exactly what is outstanding across every tax type, with the penalties and interest already accrued, so you are working from facts rather than estimates. ZRA checks are always treated as urgent in a health check, because tax exposure grows fastest.
