SANITARY LANDFILL TAX RETURN INSTRUCTIONSSLT-5A
A. DUE DATE
This return must be filed on a monthly basis by the 20th day of
the month following the close of the taxable month.
B. TAXABLE MONTH DEFINED
Taxable month means that period commencing with the first day
of the calendar month and ending with the last day of said
All taxpayers must file an Application for Registration (Form
SLT-1) with the New Jersey Division of Taxation.
All owners or operators of sanitary landfill facilities who accept
solid waste for disposal are considered to be taxpayers subject to
the Landfill Closure and Contingency Tax.
E. SANITARY LANDFILL DEFINED
A Sanitary Landfill Facility is any facility required to register as
such under New Jersey Department of Environmental Protection
F. SOLID WASTE DEFINED
“Solid waste” means all waste as defined under DEP regulation
G. SOLIDS MEASUREMENT: CUBIC YARDS VS. TONS
The Landfill Closure and Contingency Tax requires the mea-
surement of solids by cubic yards (see instruction H). However,
if your facility measures solids by the ton, provisions have been
made on the return to calculate tax due based on tons.
The conversion factors for determining volume and weight for
solids are as follows:
Volume to Weight - 3.33 cubic yards = 1 ton
Weight to Volume - .30 ton = 1 cubic yard
H. CUBIC YARD MEASUREMENT DEFINED
Solids accepted for disposal for the Landfill Closure and
Contingency Tax are to be measured in cubic yards. The volume
of solids accepted for disposal by the Sanitary Landfill Facility
must be the stated volume capacity of each container transport-
ing the waste into the landfill. In the event that no stated volume
capacity exists for a container transporting solids into a landfill,
a reasonable estimate of such waste in cubic yards is acceptable.
I. LIQUIDS MEASUREMENT
Liquid waste accepted for disposal is to be reported in gallons.
For those Sanitary Landfill Facilities that measure liquids by
weight, the conversion factor is 240 gallons per ton of liquid.
The return must be signed by an officer of the taxpayer autho-
rized to act to the effect that the statements contained therein are
true. Tax preparers who fail to sign the return or provide their
assigned tax identification number shall be liable for a $25
penalty for each such failure. If the tax preparer is not self-
employed, the name of the tax preparer’s employer and the
employer’s tax identification number should also be provided.
