Anambra State IRS Tax Portal (Tax 2.0)

The State's tax counter that never closes: get your ASIN, see your bills, pay, and print a receipt anyone can verify.

The main self-service portal of the Anambra State Internal Revenue Service. Individuals, informal businesses and companies use it to get an Anambra State Identification Number (ASIN), find and pay tax and MDA bills online, print receipts, and check that receipts and certificates are genuine. Registered taxpayers log in to a dashboard for tax filings and the electronic Tax Clearance Certificate (eTCC), and the same system serves as the back office for AIRS and MDA staff.

What it does

All 20 features

  • Create an ASIN for an individual, an informal business/enterprise or a corporate body (create-asin)
  • Identity checks while enrolling: NIN verification for individuals, CAC RC number validation for companies, and a one-time code sent by email or SMS
  • Live photo capture during enrolment, with an option to use the NIN photo instead
  • Download an ASIN card and enumeration certificate once the ASIN is generated
  • ASIN Search to look up an existing ASIN by phone number, NIN, email or ASIN
  • Pay Online three ways: Pay With ASIN, Pay With Invoice (validate an invoice number) or Pay For Property
  • MDA Services payment: choose a ministry, department or agency and its revenue item, and the fee is shown
  • Online payment through gateways including Remita and Interswitch
  • My Bills: enter an ASIN to see assessment bills
  • Demand notices for direct assessment, which can be downloaded or paid online
  • Print Receipt to reprint an e-receipt from a payment reference
  • Public Verification of payment receipts, assessment receipts, annual return certificates, stamp duty certificates, capital gains tax certificates, Tax Clearance Certificates and VAIDS certificates
  • Taxpayer login (email or ASIN plus password) to a personal or company dashboard
  • Electronic Tax Clearance Certificate (eTCC) application from the dashboard
  • Personal income tax calculator covering income, deductions, taxes already withheld and reliefs
  • Tax information pages: tax types, the federal, state and local government collection lists, tax laws and an FAQ on the new Nigerian tax laws
  • TAAS (Tax Agent Accreditation System): tax practitioners apply for accreditation, and the public can check an agent's status by accreditation or application ID
  • TAMA (Tax Audit Monitoring Agent): an oversight system for tracking tax audit cases, with an application route for firms that want to become agents
  • VAIDS 2026 page and FAQ for the Voluntary Assets and Income Declaration Scheme (window ran 6 July to 5 September 2026)
  • Staff back office for PAYE, direct, presumptive and market assessments, withholding tax, stamp duty, capital gains tax, business premises, Economic Development Levy, reconciliation and target reports

How it works

Step by step, start to finish

Get an ASIN (individual)

Step 1 of 8

Who uses it

People it serves

  • Individual taxpayers (employed and self-employed)
  • Traders, artisans and informal-sector businesses
  • Companies and corporate taxpayers
  • Employers remitting PAYE
  • Tax practitioners and consultants (TAAS)
  • Anyone checking a receipt or certificate (banks, MDAs, contracting authorities)
  • AIRS and MDA revenue staff (back office)

In practice

What it looks like

A trader in Onitsha creates an informal/enterprise ASIN on her phone and downloads her ASIN card
A resident pays an MDA fee online with his ASIN and prints the e-receipt
A company applies for its electronic Tax Clearance Certificate from its dashboard so it can bid for a government contract
A procurement officer checks a contractor's Tax Clearance Certificate on the Verification page
A taxpayer confirms that a tax consultant is accredited by entering the agent's TAAS ID

Why it matters

What changes

  • One ASIN works across State payments, so people do not have to register again for each service
  • Taxpayers can pay without going to a tax office, and receipts are generated straight away
  • Receipts and certificates can be checked by anyone, which makes fake documents harder to pass off
  • Bills, payments and certificates sit in one taxpayer record
  • Identity checks (NIN, CAC, OTP) improve the quality of the taxpayer register
