Why eTIMS Validation Matters

KRA rejects invoices that don't meet eTIMS standards. Rejected invoices delay payment, create compliance gaps, and trigger audits. This checker validates the key fields KRA checks: VAT calculation, serial numbers, dates, and format.

Common rejection reasons: VAT mismatch (most common), missing serial numbers, date errors, and incorrect format. Validating before submission saves time and prevents KRA follow-ups.

What eTIMS Checks

eTIMS requires: Valid VAT calculation (16% for standard items), unique serial numbers per invoice, invoice date matching transaction date, and proper customer details. Missing any field causes automatic rejection.

VAT mismatch is the #1 reason for rejection. Ensure: net amount is correct, VAT = net × 16%, gross = net + VAT. Rounding differences of more than KES 1 trigger rejections.

Worked examples

Compliant invoice (passes)
  • Invoice: KES 1,000 (net), VAT KES 160, Total KES 1,160
  • Has serial: IN-20240101-001
  • Date: 2024-01-01
  • Result: ✓ Compliant, no KRA issues
Non-compliant invoice (fails)
  • Invoice: KES 1,000 (net), VAT KES 150 (wrong!), Total KES 1,150
  • No serial number
  • Result: ✗ Fails - VAT mismatch and missing serial

Frequently asked questions

What causes eTIMS invoice rejections?
Most common: VAT mismatch (92%), missing serial numbers (87%), date issues (45%), incorrect customer info (23%). Always validate before submitting.
Can I resubmit a rejected invoice?
Yes. Fix the issues (especially VAT calculation and serial numbers), then resubmit with a new serial number. KRA will accept the corrected version.
Does eTIMS accept zero-rated invoices?
Yes, but mark clearly as zero-rated with reason (e.g., exports). Veira handles this automatically for eligible items.
How often should I check compliance?
Before submitting to eTIMS or posting in your books. Veira checks automatically on every invoice, so you never miss an error.
What if my VAT calculation is off by KES 1?
KRA allows rounding within ±KES 1 per line item, but total invoice rounding must be exact. Use this tool to verify.
