Service snapshot

What this due diligence page covers

Corporate tax due diligence is a transaction-focused review. It checks whether a target company has tax exposure that could transfer to the buyer, reduce valuation or require protections in the sale agreement.

For ranking and conversion, this page is built around the buyer and seller questions competitors often miss: what is reviewed, what documents are needed, what red flags matter, how risks affect deal terms and what ZeroSync delivers at the end.

Use cases

Buy-side, sell-side and investor due diligence

The same tax review produces different commercial value depending on your side of the transaction.

1

Buy-side due diligence

Find the tax risks you would inherit and use them to negotiate price, warranties, indemnities or post-completion actions.

2

Sell-side due diligence

Review your own position before buyers do, fix weaknesses early and protect the valuation during the buyer’s review.

3

Investor due diligence

Check whether the target’s corporate tax position supports the valuation, future cash flow and expected return.

4

Pre-sale clean-up

Resolve late registration, filing, disclosure, QFZP or transfer pricing issues before they become negotiation points.

5

Free zone acquisition review

Test whether claimed 0% free zone treatment is actually supported by activity, substance and income mix.

6

Post-deal integration

Turn findings into a practical action plan for restructuring, documentation and future filing readiness.

Document request

Documents and records we usually request

A focused due diligence review works best when the right evidence is requested early. This also shows visitors exactly what to prepare.

DocumentWhy it matters
Corporate tax registration and EmaraTax recordsConfirms registration status, tax period and basic compliance position
Corporate tax returns and workingsShows how tax was calculated and whether positions are supportable
Financial statements and management accountsAllows reconciliation between accounts, provisions and tax filings
Related-party agreements and ledgersIdentifies transfer pricing, connected-person and disclosure risks
Free zone licence, activity and substance evidenceTests whether any 0% QFZP position has a proper basis
FTA correspondence and penalty historyHighlights unresolved issues that may transfer with the business
Share purchase or investment documentsConnects tax findings to warranties, indemnities and completion conditions

We can scale the request list for a fast SME transaction or a deeper multi-entity acquisition. The goal is to find material issues without slowing the deal unnecessarily.

Red flags

Red flags that can change the deal value

These are the issues most likely to affect valuation, negotiation or post-acquisition clean-up.

Late registration or filing
May create penalties, delayed compliance and uncertainty around past periods.
Unsupported QFZP position
A free zone company may be claiming 0% treatment without adequate substance or qualifying income support.
No transfer pricing support
Management fees, royalties, loans or connected-person payments may not be defensible.
Return and accounts mismatch
Inconsistencies between tax returns, accounts and disclosures are easy FTA review triggers.
Unrecorded tax liabilities
Exposure may not appear clearly in the balance sheet or provisions.
Aggressive deductions or reliefs
The target may have reduced taxable income using positions that do not have enough support.

Due diligence vs health check

Due diligence is deal-driven, not a generic review

A corporate tax health check is useful for your own business at any time. Due diligence is different because it is framed around a specific deal, valuation and risk allocation.

That means the report needs to explain both the technical tax issue and the transaction consequence: what it means for price, warranties, indemnities, escrow and post-deal remediation.

FAQs

Frequently asked questions

What is corporate tax due diligence?

Corporate tax due diligence is a structured review of a target company’s UAE corporate tax position, including registration, filings, reliefs, transfer pricing, free zone status, liabilities and provisions. The aim is to identify and quantify tax exposure before a purchase, sale or investment is completed.

Why do I need tax due diligence if the company looks compliant?

A company can look compliant on the surface while still carrying unsupported positions, late registration exposure, weak transfer pricing, QFZP risk or undisclosed liabilities. Due diligence checks the evidence behind the numbers so the buyer, seller or investor understands the real position.

Do sellers need vendor tax due diligence?

Yes. Vendor due diligence lets a seller identify and fix issues before a buyer’s advisors find them. This can protect valuation, reduce delays and make the sale process more controlled.

Can tax findings reduce the purchase price?

Often, yes. Quantified exposure can support price adjustments, warranties, indemnities, escrow, completion conditions or post-completion action plans.

Does due diligence connect to structuring?

It should. Findings often affect how the transaction is structured and whether post-deal restructuring, tax grouping, QFZP planning or transfer pricing documentation is needed.

How long does a due diligence review take?

Timing depends on the size of the target, the number of entities, document quality and deal deadline. ZeroSync scopes the review first so the work matches the transaction timetable.

What is the difference between due diligence and a tax health check?

A health check is a proactive review of your own business outside a transaction. Due diligence is tied to a purchase, sale or investment and frames findings around valuation, warranties and risk allocation.

Do you quantify the risks you find?

Yes. Each material issue is explained and, where possible, sized so you can understand the likely financial impact and decide how to treat it in the transaction.
