The submit button has been pressed, the acknowledgement is saved, and for an afternoon the whole thing feels finished.
Anyone who has run a business for a few years knows better. Filing usually opens the next phase rather than closing the last one. Between July and December sit assessments, audits, objections, the amnesty window and the mid-year review — all of which reward preparation and punish drift.
Here is how to spend that period well.
1. The first three weeks
Save the official acknowledgement for every return filed — corporate, individual, VAT, PAYE — into one dedicated folder for 2025. It sounds trivial until you need it under time pressure.
Then reconcile. Put the iTax ledger beside your own books and look for assessments you were not expecting or transactions that do not match. Do this inside the first three weeks, while the detail is still fresh.
If tax is payable, pay it. Interest accrues quietly and there is no version of this where waiting is cheaper.
2. Strengthen the record behind the return
Cross-check 2025 sales and purchases against eTIMS and correct mismatches before automated validation finds them for you. Pull together bank statements, supplier invoices, contracts and delivery notes — KRA can and does ask for these after filing. Review the fixed asset register too, and satisfy yourself that the capital allowances claimed are properly supported.
3. Be ready for notices
Notices commonly arrive one to three months after filing. The usual triggers are income and expense data that do not reconcile, bank deposits without an explanation, and expenses disallowed for missing eTIMS invoices.
When one lands, respond inside the stated window — normally 30 days. Assemble your evidence before you reply, object formally where you genuinely disagree, and bring an advisor in early. Cases prepared properly at the outset resolve far better than cases rescued later.
4. Use the amnesty while it is open
Finance Bill 2026 extended the window. If you carry liabilities up to December 2025, declaring and paying the principal now brings reduced penalties and interest, tidies your record and improves your standing for a Tax Compliance Certificate.
Check the ledger for anything that qualifies and apply before the deadline rather than near it.
5. Run the mid-year health check
July and August are the natural moment for it. Confirm you are reserving monthly for VAT, PAYE and corporate tax. Check every invoice is eTIMS-compliant and reconcile input against output VAT. Verify NSSF, SHIF and the Housing Levy are calculated and remitted correctly. Project the current year’s likely liability. And if tenders or lending are on the horizon, get the TCC renewed now rather than at the point of need.
6. The mistakes that cost most
- Ignoring a small notice until it has grown into a large assessment
- Leaving the same iTax password in place year after year — change it after filing
- Missing the deadline to respond to a query
- Blending personal and business expenses, which remains a reliable audit trigger
7. Prepare for the next cycle
The four-month filing deadline for 2026 returns is tighter than businesses are used to. Get your team or accountant closing faster, and consider whether your accounting software is genuinely built for eTIMS or merely tolerating it.
In closing
Filing the 2025 returns mattered, but the second half of the year is where the risk actually sits. Businesses that reconcile, answer notices promptly, use the amnesty and plan ahead materially reduce their exposure to penalties and unexpected demands.
In a difficult economy, being organised about tax is one of the more reliable ways to protect both cash flow and your own peace of mind.
