How To Calculate and Know Your Annual Taxable Income in 2026

Nigeria’s payroll landscape is changing, and employers can’t afford to “calculate later.” With the Annual Taxable Income (ATI) tax reform bands effective from January 1, 2026, HR teams, finance managers, and business owners must review payroll structures, employee taxable components, and reporting workflows—early.

The new tax bands introduce clearer income thresholds and rates, and while the structure looks straightforward on paper, the real compliance work happens inside your monthly payroll cycle.

The 2026 Annual Taxable Income (ATI) Tax Reform Bands (At a Glance)

The 2026 reform applies progressive rates based on ATI thresholds, including:

• Up to ?800,000 — 0%

• 800,001 to ?3,000,000 — 15%

• 3,000,001 to ?12,000,000 — 18%

• 12,000,001 to ?25,000,000 — 21%

• 25,000,001 to ?50,000,000 — 23%

• Above 50,000,000 — 25%

This means employees are taxed in layers—so accurate band application matters.

What This Means for Employers in 2026

1) Payroll calculations must be more precise

The days of “rough estimates” and manual spreadsheets are officially risky. With band-based tax computation, a small error in ATI breakdown can cause:

• incorrect PAYE deductions

• payroll disputes

• compliance gaps and penalties

2) Employee taxable income must be properly structured

ATI isn’t just salary—it can include multiple taxable components depending on payroll structure and allowances. Employers need to ensure:

• correct classification of earnings

• proper deductions and taxable items mapping

• consistent documentation

3) Compliance reporting becomes non-negotiable

When tax rules change, regulatory attention increases. Employers should expect stronger expectations around:

• payroll tax accuracy

• audit readiness

• clean employee tax history

Why Many Businesses Will Struggle Without the Right System

Even if you understand the tax bands, compliance becomes difficult when you have:

• multiple salary grades

• frequent payroll adjustments

• bonuses, allowances, and reimbursements

• staff movement (new hires, resignations, promotions)

• multiple branches or payroll locations

Manual payroll methods can’t keep up with real-time changes—and that’s where most compliance failures start.
