# Tax disputes from mergers and acquisitions: the situation
Mergers concentrate tax risk: valuations, restructuring relief conditions, successor liability, and the allocation of pre-merger exposures.
The dispute file needs the deal file: the merger agreement, valuations at the time, restructuring relief claims with their conditions evidenced, and the pre-merger compliance position of each party. Successor liability questions — who answers for pre-merger periods — need settling before the dispute, not during it.
# Dispute strategy
A post-merger assessment for a pre-merger period: establish who is the proper disputant, gather the target's historical records (often neglected post-deal), and dispute within the 40 days. Deal document retention clauses exist for exactly this moment.
Watchouts
- The deal file is the dispute file — preserve it through integration
- Settle successor-liability questions before filing
- Pre-merger periods need the target's records — retrieve them early
# Procedure: which rung of the ladder
The 40-business-day windows run from notification to whoever is now the proper person. Ensure notifications reach the right hands post-merger — restructured groups lose assessments in the mail.

# Running this dispute well: practical guidance
Beyond the legal strategy, the practical running of this dispute determines its outcome. Cases are rarely lost on the law alone — they are lost on missed windows, disorganized files, and strategies never reassessed. The FTA and the Committee decide dozens of cases; the file that is complete, coherent, and on time gets the fair hearing its merits deserve. Run these disciplines from the first notification, not from the first setback. Four disciplines apply:
Control the timetable from day one
Diary every deadline the moment a notification arrives: the 40-business-day reconsideration or review window, the FTA's 40+5 business-day decision period, the 40-business-day TDRC objection window, and the 40-business-day court window. Count business days only, verify independently, and work to the 10-day mark — not the deadline. A post-merger assessment for a pre-merger period: establish who is the proper disputant, gather the target's historical records (often neglected post-...
Keep the file litigation-ready
Maintain one master file from the start: every notification with its proof, every filing reference, every payment confirmation, every decision. Organize it as the bundle you would file tomorrow — indexed, chronological, every page numbered. A dispute that is always ready to file is a dispute that never misses a window scrambling for documents.
Watch the watchouts
The risks identified above are not theoretical: The deal file is the dispute file — preserve it through integration Settle successor-liability questions before filing Review them monthly while the dispute runs. New facts can change the strategy — a fresh assessment, a payment made, a deadline shifted by a holiday announcement — so reassess the plan each time the file changes, not just at the start.
Know when the economics change
Reassess proportionality at each rung: the amount at stake, the cost of the next stage, and the strength of the surviving grounds. A dispute worth running at reconsideration may not be worth running at court once the 50%-of-penalties security is factored in. Settle or seek instalments where the economics turn — persistence is a virtue only while it pays.
Document everything as you go
Write the file as it happens: a dated note for every call, every decision, every payment. Memory fades and staff change; the contemporaneous note does not. When the next rung arrives — or the FTA queries a related period years later — the documented file answers questions that an undocumented one cannot. Good records are the cheapest insurance in tax disputes. Store the file where successors can find it; a dispute file that leaves with a departing employee is a liability, not an asset.

Frequently asked questions
Do I need a tax agent or lawyer for this?
Not legally required at reconsideration or the TDRC, but the complexity of the issue should decide. Document-heavy factual disputes can be self-filed with care; methodology fights, status cases, and court appeals repay professional handling. Weigh the amount at stake against the fee.
What is the very first thing to do?
Diary the notification date with its proof — screenshot the EmaraTax timestamp — and preserve every relevant document immediately. Then compute the 40-business-day deadline and work backwards. Everything strategic flows from those two acts: the clock secured, the evidence safe.
Who disputes pre-merger tax assessments?
The successor entity generally, under the merger's legal mechanics — but the constitutional documents and the FTA's records must align. Confirm the proper disputant at the outset; filing in the wrong name wastes the window.
