tax bracket
Tax Bracket is the income band that decides what rate of tax applies to your earnings, with higher slices of income often taxed at higher rates.
In plain English
"Ah ah, so if I collect this promotion, will I more than be working for tax now?" Ngozi asked her cousin Bode, staring at the offer letter like it had insulted her.
Bode laughed and shook his head. "That is the biggest myth in this whole tax matter. Moving into a higher tax bracket does not mean your whole salary gets taxed at that new rate. It only means the extra money, the new slice above the old line, gets taxed higher. Everything you were already earning stays taxed the way it was."
This is what a tax bracket really means. Under Nigeria's personal income tax system, income is taxed in bands, so the first portion is taxed lightly or not at all, the next portion at a slightly higher rate, and so on as you climb. Nobody's entire income gets swallowed by one rate.
It works the same way in the United Kingdom, where someone moving from the basic rate band into the higher rate band only pays the higher rate on the income that sits above the threshold, not on every pound they have ever earned.
For someone in the diaspora sending money home, this matters too. A UK based Nigerian nurse who gets a raise and crosses into a higher band there will still keep more of that raise than she loses to tax, because only the portion above the line is taxed at the new rate.
Understanding this stops people from turning down raises out of fear, which happens more often than you would think.
Say Nigeria's bands tax the first ₦800,000 at a lower rate and anything above that up to a certain point at a higher rate. If Chidi earns ₦1,200,000 a year, only the ₦400,000 above the ₦800,000 line is taxed at the higher rate. The first ₦800,000 keeps its original, gentler rate.
Questions people ask
Does moving to a higher tax bracket mean I lose money overall?
No. You will always take home more than you did before the raise, because only the income above the threshold is taxed at the higher rate, not your entire earnings.
How do I know which tax bracket I fall into?
Check the current personal income tax bands published by the tax authority, then see where your annual taxable income lands after allowable reliefs and deductions are subtracted.
Do tax brackets change every year?
They can, especially when governments adjust thresholds for inflation or introduce reforms, so it is worth checking each tax year rather than assuming last year's bands still apply.
