(1)Where any adjustment is made of the liability of any person to excess profits tax or the national defence contribution, any consequential adjustment of the liability of that or any other person to income tax (including surtax) for any year of assessment may be made, whether by way of additional assessment, repayment of tax or otherwise, notwithstanding that the time limited by the Income Tax Acts for the making of assessments or claims for repayment of tax has expired.
(2)Section forty-one of the Finance Act, 1927 (which contains provisions with respect to the making and determination of claims) shall apply in relation to claims for relief from income tax (other than surtax) consequential on any adjustment as respects excess profits tax or the national defence contribution as it applies in relation to claims for deductions of tax under section forty of that Act:
Provided that any such claim to which objection is made shall, if the claimant so elects when he makes the claim, be heard and determined by the Special Commissioners, and subsection (2) of the said section forty-one shall have effect accordingly.
