Company Details

What Is the Development Levy?

The 4% Development Levy is a consolidated charge introduced by the NTA 2025 that replaces four separate levies: Tertiary Education Tax (TET, 2.5%), Information Technology Development Levy (ITDL, 1%), NASENI Levy, and Police Trust Fund Levy. It is charged on assessable profits — that is, taxable profits before deducting capital allowances and losses brought forward.

Who Pays the Development Levy?

All standard companies (turnover above ₦100 million) are liable for the Development Levy. Small companies (turnover ≤ ₦100M and total assets ≤ ₦250M) are exempt. The classification is reassessed each tax year based on the company’s most recent financial statements. Professional services firms cannot qualify as small regardless of turnover.

How It Differs from the Old Levies

Under the old regime, TET (2.5%) was paid to the Tertiary Education Trust Fund, ITDL (1%) to NITDA, and the other levies to their respective agencies. Companies had to file separate returns for each. The NTA 2025 consolidates all four into a single 4% payment administered by the NRS, simplifying compliance. The combined effective rate is virtually unchanged (3.5% vs 4%), but the single filing saves significant administrative effort.
