Can this assessment be contested — and on what grounds?
The first question we answer in any tax consultation
a conclusion served in numbers, answered in writing, proven with grounds.
Glaw Law Group does not inflate the odds. We begin with a precise diagnosis rather than vague hope, and prove the case in writing — through thorough analysis of the books, careful review of the vouchers, and logic that reaches the substance of each transaction.

APPEAL STATISTICS
Tax appeals, in numbers
The share of NTS-level appeals ending with the assessment set aside or corrected has risen four years straight — to 21.1%. One appeal in five changes the outcome.
A tax bill left uncontested becomes final once the deadline passes. Before you accept it, find out whether it can be fought.
| Year | NTS acceptance rate |
|---|---|
| 2022 | 11.5% |
| 2023 | 13.1% |
| 2024 | 13.9% |

PRINCIPLES
Principles settled before any outcome

01
A precise diagnosis comes first
Saying a case can be won is easy. From the first consultation we separate what can be contested from what is better accepted — and show you the grounds for that judgment.

02
Strategy and deadlines both matter
Thirty days for pre-assessment review, ninety for administrative appeals and litigation. Miss the deadline and even a sound argument loses its forum. In every case we fix the deadlines first and build a rigorous strategy on that clock.

03
The attorney who takes your case keeps it
We accept few cases. The attorney you meet at the consultation attends the audit, drafts the filings, and argues in court — and explains each step in plain language.
PRACTICE AREAS
Every branch of tax controversy
From audit response to Tribunal appeals and litigation, from inheritance and gift tax to international tax: each branch has its own procedure and issues, so Glaw divides tax practice into its core branches and treats each in depth.
STAGE BY STAGE
From audit to litigation, one unbroken line
As a tax case moves, the opponent and the rules change: facts at the audit, procedure at the Tribunal, doctrine in court. The direction set at the start is carried through to the end by the same attorney.
Tax Audit
The first written answer sets the course
The days right after an audit notice matter most. We review the scope of the document requests, organize the substance of the transactions first, and put the direction of the whole case into the first written explanation. An attorney attends the audit itself.
Appeals
The chance to correct it before court
Pre-assessment review and Tribunal appeals can change the conclusion earlier than any lawsuit. Within the 30- and 90-day windows we narrow the issues and draft the appeal with the courtroom already in view.
Tax Litigation
The last stage, argued with the most precision
We classify the grounds of illegality, build the proof plan, and structure the argument — and consider a case finished only when the refund and follow-up procedures after judgment are complete.

CONSULTATION
The appeal clock is already running
Ninety days from learning of the assessment for a Tribunal appeal; thirty days for pre-assessment review. Once a deadline passes, even a sound argument has fewer places to go. Finding out what is still possible at your stage — that is where a response begins.
