ness. Receipts in this State shall be held to include in addi-
tion to all receipts from business commencing and termi-
nating within this State such portion of receipts from all
interstate business passing through or into or out of the State
as is determined by applying to gross receipts from all busi-
ness of transportation and communication enterprises that
percentage which the mileage within the State over which such
business was carried bears to the entire mileage over which
it was carried. (The Comptroller shall prescribe methods of
allocating receipts of other utilities. ) Accounts receivable
from services rendered and other sources arising from busi-
ness during the year shall be included in the formula if the
corporation's return is made on the accrual basis.

(d) Provided, however, that if such public utility keeps its
records of operating revenues and operating expenses on a
State basis in accordance with the standard classification of
accounts prescribed by the Federal Communication Commission
and/or Interstate Commerce Commission, and in such manner
as to include in net income for the State the effect of all intra-

such records may be used by the taxpayer in reporting the
net taxable income within the State.

248. TAX A PERSONAL DEBT. Every tax imposed by this
sub-title, and all increases, interest and penalties thereon,
shall become, from the time it is due and payable, a personal
debt, from the person or persons liable to pay the same to
this State, and shall be entitled to the same priority as other
State taxes.

249. PENALTY AND INTEREST. If taxes imposed by this sub-
title be not paid when due, as provided herein, the taxpayer
liable to such tax shall pay as a penalty, in addition to the
amount of such tax, an additional tax of five per cent (5%)
of such amount, plus one per cent (1%) for each month the
tax or additional tax remains unpaid; but the Comptroller
upon submission to him of satisfactory evidence that the
failure to pay such tax within the time prescribed in this
sub-title was not wilful or evasive, may modify the exaction
to not less than one per cent (1%) for each month following
the due date of the tax.

250. DISCONTINUATION OF BUSINESS. If any corporation
shall dissolve or withdraw from this State during any
taxable year, or if any corporation shall in any manner
surrender or lose its charter during any taxable year, such
dissolution, withdrawal or loss or surrender of charter, shall
not defeat the filing of returns and the assessment and col-
