Tax Consultants in Warri: Federal and State Tax Advisory

Know exactly where your FIRS and DBIR records disagree, before either authority finds it for you.

Warri businesses answer to two tax authorities that don’t always align. FIRS collects Company Income Tax, VAT, and Withholding Tax federally. DBIR collects Personal Income Tax, Business Premises Tax, and Development Levy at the state level. Where the two drift apart, and they do, the gap surfaces at the worst possible moment, a bank facility review or a FIRS audit notice. Missed WHT on a subcontract or a misclassified VAT position can cost far more to fix under audit pressure than to correct now.

Matthew Ogagavworia & Co. (Chartered Accountants), led by an FCA with over 25 years in practice, handles FIRS filings, DBIR registration and remittance, and tax planning built specifically around Warri’s oil and gas services economy, not a generic reading of the tax code applied to whatever client walks in.

We’ve mapped enough subcontract chains in this sector to know that the WHT question is rarely about the headline rate. It’s about which party in a three- or four-layer subcontract structure actually holds the deduction obligation, and whether that obligation was met at every layer. Getting that wrong doesn’t show up immediately. It shows up eighteen months later as a FIRS query covering a period you’ve already closed your books on.

Two Authorities, One Reconciled Position

Every business operating in Warri needs a Tax Identification Number registered with both authorities. Here’s what each one actually collects, and where the exposure typically sits:

The gap between NRS and DBIR records rarely opens all at once. It builds one missed reconciliation at a time, a WHT deduction skipped on one invoice, a payroll figure that changed after DBIR registration but was never updated. By the time a bank or FIRS notices, the gap can span several years. A health check exists to find and close that gap on your terms, not theirs.

A common pattern: a business registers with FIRS the day it incorporates, files CIT and VAT reasonably consistently for years, but never completes DBIR registration because no one flagged it as a separate requirement. The company isn’t hiding anything, it simply never happened. That gap sits quietly until the company applies for a bank facility and the bank’s compliance team asks for a DBIR tax clearance certificate that doesn’t exist. What would have been a two-week registration exercise handled proactively becomes a facility approval delayed by months while the company scrambles to regularise years of history under time pressure.

Who This Is For

We work with Warri businesses at three distinct points in their tax journey:

Established operators with years of filing history — who suspect, correctly in most cases, that their FIRS and DBIR records have drifted apart somewhere along the way.

Growing businesses handling their first major IOC or NNPC-linked contract — where the JV billing structure introduces WHT and VAT questions the business hasn’t faced before.

Companies responding to an active FIRS or DBIR query — who need direct representation now, even though earlier engagement would have given us more room to build the position in advance.

Why Choose Us

Sector-specific tax knowledge. WHT on subcontracts and VAT classification for oilfield services, not a generic reading of the VAT Act. We know which questions to ask about your subcontract chain because we’ve mapped this structure before.

Proactive, not reactive. We find your exposure through a health check, before FIRS or DBIR finds it for you, when you still have room to correct the position rather than defend it under audit pressure.

Integrated with our audit practice. Your tax position and your audited financial statements are handled by the same team, so the two stay consistent with each other rather than drifting apart across separate advisers.

Our Process

1. Tax health check — two to three years of filings reviewed against both FIRS and DBIR records to establish exactly where the gaps sit.
2. Registration and reconciliation — TIN registration completed with whichever authority you’re missing, historical records reconciled between the two.
3. WHT and VAT correction — subcontract structure and service classifications reviewed line by line, treatment corrected going forward rather than left to compound.
4. Ongoing filing — monthly and annual FIRS and DBIR returns filed on your behalf, ahead of deadlines, with confirmation sent to you at each stage.
5. Dispute representation — where FIRS or DBIR raises a query, we represent you directly rather than leaving you to manage the correspondence alone.

Related Services

Warri tax advisory rarely stands alone. These services connect most often to the work above:

Audit Firms in Warri — statutory audit for the same oil and gas service companies we advise on tax, so your financial statements and your tax filings reconcile.

Company Secretarial Services — corporate records and CAC filings kept current alongside your tax compliance.

Debt Recovery Services — where unpaid receivables from JV or subcontract arrangements need formal recovery action.

Pricing

We price tax engagements by scope, not a flat published rate, because exposure depends on your contract structure and filing history, not just your headcount. Fee drivers typically include:

• The number of years covered in the initial tax health check
• The complexity of your subcontract chain and WHT exposure
• Whether expatriate staff are involved
• Whether an active FIRS or DBIR query needs representation

You receive a written engagement letter with the fee, scope, and timeline agreed before any work begins. No engagement proceeds on a verbal estimate.

Frequently Asked Questions

We already have a TIN. Why would we need a tax health check?

A TIN doesn’t confirm your filings are correct, or that your FIRS and DBIR records agree with each other. A health check tells you where the gaps actually are before either authority finds them.

Can you help with a NRS  audit that’s already started?

Yes. We can step in mid-audit to represent you, though engaging earlier gives us more room to build your position first.

Do you handle expatriate quota and PAYE together?

Yes, as one coordinated process for staff resident in Delta State, working alongside your immigration adviser where quota renewal is involved.

Do you file our monthly VAT and WHT returns for us?

Yes, as part of an ongoing engagement, with confirmation sent to you each time a filing is submitted.

What do you need from us to start a health check?

Your last two to three years of NRS and DBIR filings, your TIN registration documents, and access to your accounting records.

Can you review a contract before we sign it, to flag WHT and VAT implications upfront?

Yes. Reviewing the tax treatment of a major subcontract or charter agreement before signature is one of the more valuable things we do, since correcting a structure after the fact is far harder than getting it right at the outset.

We’re a small equipment rental business with two clients. Is a full health check overkill for us?

Not necessarily. Exposure scales with contract value and structure, not just headcount. We scope the health check to your actual size, and for a small operation that can be a focused, low-cost exercise.

How do you charge for ongoing compliance versus a one-time health check?

Monthly compliance is priced as a retainer covering your filing volume. A health check is priced separately as a fixed-scope project. Many clients start with the health check and move to a retainer once their position is corrected.

If the health check finds a serious gap, are we at immediate risk of a NRS penalty?

Not automatically. A voluntary, proactive correction is treated very differently from a gap FIRS discovers on its own. We help you assess the exposure and, where appropriate, approach the correction in a way that minimises penalty risk.

Can you work alongside our existing accountant rather than replacing them?

Yes. Many of our Warri tax engagements run alongside a client’s existing in-house or external accountant, with us handling the FIRS and DBIR-specific work while your accountant continues managing day-to-day bookkeeping.

Our subcontractors are based in Lagos but the work is performed in Warri. Does that change the WHT position?

It can affect which tax office handles specific correspondence, though the underlying WHT deduction and remittance obligation follows the transaction, not the subcontractor’s registered address. We confirm the correct treatment as part of the health check rather than assuming location alone settles the question.

How quickly can you respond if NRS issues a query while we’re mid-engagement?

Immediately. An active query takes priority over scheduled work, and as your point of contact we respond directly to FIRS or DBIR correspondence within the timeframe the notice requires, keeping you informed at every step rather than leaving you to interpret the notice alone.

Is a tax health check a one-time report, or do you help implement the corrections too?

Both. The health check identifies the gaps, but the engagement doesn’t stop at the report. We carry the corrections through, registration fixes, revised WHT and VAT treatment, and reconciled remittances, so you’re not left holding a list of problems with no one to action them.

If we switch to you mid-year, will our tax filing history need to be reworked from January?

Not necessarily. We review what’s already been filed for the year and correct only what needs correcting going forward, rather than automatically reopening every prior filing. A full historical review happens where the health check finds it’s genuinely warranted.

What Happens After You Reach Out

1. A confidential call — to understand your contract structure, your subcontract chain, and what’s prompting the enquiry, whether that’s a proactive check or an active NRS or DBIR notice.
2. A written engagement letter — with the fee, scope, and timeline for the health check or ongoing compliance work agreed before anything begins.
3. A named point of contact — who reviews your filings, corrects what needs correcting, and represents you directly if either authority raises a query.

Common Compliance Mistakes to Avoid

The costliest mistakes we see among Warri oil and gas service clients are usually avoidable with earlier advice:

• Treating WHT as the subcontractor’s problem rather than confirming your own deduction and remittance obligation as the paying party
• Applying VAT zero-rating to a service without confirming it actually qualifies, which creates exposure the opposite way once NRS reviews the classification
• Paying expatriate staff through arrangements that don’t align PAYE with expatriate quota compliance, creating two separate problems instead of one coordinated position
• Letting monthly VAT and WHT filings slip during busy operational periods, when penalties for late filing compound faster than most businesses expect
• Only engaging a tax adviser once a FIRS query has already arrived, losing the chance to build a defensible position in advance
