How Do Federal Workers in Nigeria File Personal Income Tax When They Have Side Hustles in Addition to Salary?

Got it — let’s break this carefully. Since you’re a federal employee living in Taraba State with PAYE deductions and a side hustle, your tax filing involves combining your employment income with your other income from the side business. Here’s how to approach it:
1. Understand Your Tax Situation
As a federal worker: Your PAYE (Pay-As-You-Earn) is already deducted by your employer monthly. This covers your personal income tax (PIT) for employment income.
Side hustle: Any income from your side business (freelance, sales, consulting, etc.) is additional taxable income. You are responsible for declaring this when filing your annual tax return.
⚠️ Even though your salary is taxed at source, your side hustle income must be added to your total income when filing PIT.
2. Collect Your Income Records
From employment: Obtain a PAYE summary or a certificate of tax deduction from your employer. This shows how much tax has been deducted for the year.
From your side hustle: Gather all receipts, invoices, bank statements, or sales records. This is your taxable income outside employment.
3. Determine Your Total Taxable Income
Total taxable income = salary income after allowable deductions + side hustle profit.
Allowable deductions may include pension contributions, life insurance, and other approved reliefs.
4. Filing Your Tax Return
In Nigeria, you can file PIT either online via the state tax portal (Taraba State) or at a Physical State Internal Revenue Service (SIRS) office. Steps:
Register or log in with your TIN (use your personal TIN from employment).
Input your salary information (from PAYE certificate).
Add side hustle income: Declare the total gross income from your side business.
Calculate tax: The system will adjust for PAYE already deducted from your salary and compute any additional tax owed on side hustle income.
Submit and pay any balance if required.
5. Reconciling PAYE with Side Hustle
Your employer has already paid tax on your salary.
Your side hustle is taxed separately, but the PIT system aggregates all income.
If your PAYE exceeds the total liability after including side hustle, you may not owe extra.
If side hustle pushes your total income higher, you may have additional tax to pay.
6. Tips to Avoid Penalties
Keep clear records for your side hustle.
Don’t mix personal and business money.
File before the annual deadline (usually April for the previous year).
Claim all allowable deductions and reliefs.
