Form 47 — Instructions
Mine License Tax Return
File Form 47 for each year you mine or receive
royalties from mining any of the following: quartz,
quartzite, gold, silver, copper, lead, zinc, coal,
phosphate, limestone, stone from quarries, or other
metals or minerals. Even if no tax is due, you must
file Form 47 each year until mining operations have
permanently ceased. Use the same tax year on
your Form 47 as you used on your federal income
tax return.
The tax is due on the 15th day of the fourth month
following the end of the tax year. If you have an
automatic six-month extension of time to file your
income tax return, you have the same extension of
time to file your Form 47.
File a separate return for each mine or group of
mines. If you own two or more separate mines,
only those mines grouped to compute the depletion
allowable for federal income tax purposes can be
treated as one property.
Use Method A or Method B to compute the mine
license tax if you mine ores on public lands that
the U.S. Department of Interior computes mineral
values for federal royalty purposes. Include your
written election with the first Idaho Mine License
Tax Return you file. To change methods, get written
permission from the Tax Commission before your
tax return is due. If you receive royalties or if you
don’t elect Method B, use Method A.
Determine the net value separately if your mining
activity includes both receiving royalties and
extracting ores. The separate determinations can’t
be netted together or offset against each other.

Amended Returns
You can use this form as an original return or an
amended return. If you’re filing this form as an
amended return, check the box at the top of the
form. Enter the applicable reasons for amending
as listed below. Complete the entire form using the

Mine License Account Number
Enter the nine-digit mine license account number
provided by the Tax Commission for this mine or
group of mines. If this is the initial return for this
mine or group of mines, leave this line blank. File a
separate return for each account number.

Cyanidation Facilities
Cyanidation is the method of extracting precious
metals from ores by treatment with cyanide solution as
the primary leaching agent. If your mining operation
includes a cyanidation facility, check the box in the
area above line 1.

Initial Return
If this is your first year of mining this location in Idaho,
check the Initial Return box in the area above line 1.

Final Return
Filing using Method A. If you’ve permanently
ceased all mining operations at this location and sold
all stockpiled inventory, check the Final Return box in
the area above line 1.
Filing using Method B. If you’ve permanently
ceased all mining operations at this location, check
the Final Return box in the area above line 1.

How to Compute the Tax
Method A
Use this method if you receive royalties or if you
didn’t elect Method B. This method of computing net
value of ores mined or royalties received is found in
Idaho Code section 47-1202(a).
Line 1. Enter the taxable income from mining
(defined in Section 613 of the Internal Revenue
Code and Treasury Regulation 1.613-5) or the gross
amount received as royalties. This is the amount
used in your federal percentage depletion expense
computation.
Line 2. Enter the depletion expense allowed on
your federal income tax return related to the receipts
reported on line 1 of this return. Include a copy of the
federal depletion expense computation.
