Running a business in Nigeria is hard enough without FIRS breathing down your neck. Yet every day, we see smart business owners making these costly mistakes:
1. 𝐍𝐎𝐓 𝐑𝐄𝐆𝐈𝐒𝐓𝐄𝐑𝐈𝐍𝐆 𝐅𝐎𝐑 𝐓𝐀𝐗 𝐄𝐀𝐑𝐋𝐘
Waiting until you're "big enough"? FIRS(NIRS) doesn't care about your revenue size. From the moment you start trading, you should be registered. The penalties for late registration can hit ₦50,000 before you even file your first return.
2. 𝐌𝐈𝐗𝐈𝐍𝐆 𝐏𝐄𝐑𝐒𝐎𝐍𝐀𝐋 & 𝐁𝐔𝐒𝐈𝐍𝐄𝐒𝐒 𝐄𝐗𝐏𝐄𝐍𝐒𝐄𝐒
That Sunday Jollof at home ≠ business expense. Your Netflix subscription ≠ office supplies. FIRS(NIRS) auditors know the difference, and claiming personal expenses can trigger a full audit. Keep them separate or risk losing ALL your deductions.
3.𝐈𝐆𝐍𝐎𝐑𝐈𝐍𝐆 𝐖𝐈𝐓𝐇𝐇𝐎𝐋𝐃𝐈𝐍𝐆 𝐓𝐀𝐗 (𝐖𝐇𝐓)
If you're paying vendors, contractors, or suppliers, you're legally required to withhold and remit 5-10% WHT. Miss this and you're personally liable for both the tax AND penalties. It adds up fast.
4. 𝐍𝐎 𝐏𝐑𝐎𝐏𝐄𝐑 𝐄𝐗𝐏𝐄𝐍𝐒𝐄 𝐑𝐄𝐂𝐄𝐈𝐏𝐓𝐒
"But I paid via transfer!" doesn't cut it. WhatsApp payment confirmations aren't valid proof for FIRS(NIRS). You need proper invoices with TIN, date, and itemization. No receipt = no deduction = higher taxes.
5. 𝐅𝐈𝐋𝐈𝐍𝐆 𝐋𝐀𝐓𝐄 (𝐎𝐫 𝐍𝐨𝐭 𝐀𝐭 𝐀𝐥𝐥)
FIRS(NIRS) late filing penalties start at ₦50,000 and a monthly fee for every delay. One late company income tax filing can cost more than hiring a professional accountant for an entire year. The math literally doesn't make sense.
Saying "my accountant will handle it" only works if you actually HAVE an accountant checking these things. 🎯
The good news? We've filed 500+ tax returns with ZERO penalties for our clients.
