New York Advisory Opinion TSB-A-96(42)S: Is a specific method of waterproofing leaking basement wall cracks -- installing a permanent interior drainage system rather than patching the cracks -- a tax-exempt capital improvement or a taxable repair service?

Plain-English summary

Sta Dry Systems Inc. does not repair, patch, or inject material into cracked basement walls. Instead, its "pressure-relief" waterproofing system permanently reroutes water seeping through basement wall cracks (or general wall seepage) down into the home's floor drainage system. The installation involves carefully grooving out a wall crack, inserting flexible tubing down to the footer, permanently riveting a proprietary rigid fiberglass sealer (guaranteed never to deteriorate or leak) over the crack area extending below the floor, and recementing the floor opening -- or, for general wall seepage without a specific crack, installing drainboard alone to channel water below the floor. The whole system is unconditionally guaranteed for the life of the house. Sta Dry asked whether this counts as an exempt "capital improvement" or a taxable repair service.

The Department found it's a capital improvement. Applying the three-part statutory test (Tax Law § 1101(b)(9)) as explained in the Tax Appeals Tribunal's F.W. Woolworth decision, the system (1) substantially adds value and prolongs the property's useful life by eliminating water flow and the resulting mildew/rot damage to walls, ceiling supports, and furnishings; (2) becomes permanently affixed to the real property, since it's riveted and cemented in place and removal would cause material damage; and (3) is intended as a permanent installation, backed by a lifetime guarantee. Because the "end result" of Sta Dry's work is a lasting structural fix rather than a temporary repair, its labor and materials charge to homeowners is exempt from sales tax under Tax Law §§ 1105(c)(3)(iii) and 1115(a)(17). Sta Dry should obtain a properly completed Capital Improvement Certificate (Form ST-124) from each customer to document the exempt sale, but Sta Dry itself still owes sales or use tax on the materials it purchases to install the system, since a capital-improvement contractor is the ultimate consumer of its own materials.

What this means for you

Waterproofing and basement drainage contractors

A permanent, structurally integrated drainage/waterproofing fix -- riveted or cemented in place, with a durability guarantee, that eliminates rather than merely manages the leak -- can qualify as a capital improvement even without ever repairing the crack itself. Document each qualifying job with a Capital Improvement Certificate from the homeowner, and remember you still pay sales tax on your own materials regardless of the customer-facing exemption.

Homeowners hiring a waterproofing contractor

If your contractor's method is designed as a permanent structural fix (not a patch, sealant injection, or temporary measure), ask whether the job qualifies as a capital improvement -- if so, you shouldn't be charged sales tax on the labor and materials, and you should sign a Capital Improvement Certificate for the contractor's records.

Common questions

Q: Why does it matter that Sta Dry doesn't patch or inject the crack itself?
A: The Department's analysis focuses on the "end result" of the work (per 20 NYCRR 527.7(b)(4)) -- a system that permanently reroutes and eliminates the water problem, rather than one that merely patches or repairs the existing crack, reads as a lasting structural addition rather than ordinary maintenance or repair.

Q: Would a simple crack-sealing or patching job get the same result?
A: This opinion doesn't say -- it's limited to Sta Dry's specific permanently affixed, guaranteed drainage system. A basic patch or injection repair, without the same permanence and structural integration, would more likely be treated as a taxable repair service under Tax Law § 1105(c)(5) rather than a capital improvement.

Q: Who pays the sales tax under this ruling?
A: The contractor does, on its own material purchases -- not the homeowner. The homeowner's payment to the contractor for the finished capital improvement is exempt.

Q: Can another waterproofing company rely on this exact result for its own different method?
A: No. This advisory opinion binds the Department only as to Sta Dry Systems Inc. and its specific described method; a company using a different technique (e.g., one that patches cracks rather than permanently rerouting water) should confirm its own process against the three-part test before assuming the same exempt treatment.

ADVISORY OPINION

PETITION NO. S960223A

On February 23, 1996, the Department of Taxation and Finance received a Petition for
Advisory Opinion from Sta Dry Systems Inc., 3527 Harlem Road, Cheektowaga, New York 14225.
The issue raised by Petitioner, Sta Dry Systems Inc., is whether a particular method of
waterproofing leaking basement wall cracks constitutes a capital improvement or a taxable repair
service to real property.
Petitioner presents the following facts.
Petitioner's waterproofing system is used on leaking basement wall cracks. Petitioner is not
in the business of repairing, patching or injecting material into cracks. Petitioner's waterproofing
system is designed to channel or re-route water that seeps through basement walls into a floor
drainage system floor sump pump. Petitioner does not advertise or perform foundation repairs.
Wall leakage is channeled by installing vertical piping and fiberglass drainboard, which
extend below the floor, in specified wall areas. Alternatively, in the case of a general overall
condition of walls leaking, drainboard alone is installed on the walls to divert water to below the
floor. In both cases, either existing drain pipes under the floor may be used for connecting drainage
if they are functioning, or Petitioner installs new drainage.
Petitioner's wall drainage system (referred to as a pressure-relief system) is designed to allow
the leaking water simply to drain down permanently along the inside surface of the wall. NO attempt
is ever made to repair, patch, or inject cracked areas. Petitioner's wall drainage system is only
concerned with re-routing water to a floor drainage system.
Background materials submitted by Petitioner describe the procedures for installing the wall
drainage system as follows:
STEP 1 - A plastic tent is erected around the work area to prevent debris from entering other
basement areas.
STEP 2 - A section of the existing floor adjacent to the wall is temporarily removed. This section
is at least 2 feet wide and extends down to the depth of the existing floor drainage system (e.g. drain
tile/crushed stone).
STEP 3 - The crack in the wall itself is carefully Veed-Out from grade level to the footer with an
electric hammer.
STEP 4 - A flexible half-moon plastic tubing is inserted into the wall following the prepared groove.
It extends to below the floor, over the footer, and sets adjacent to the exposed drain tile/ crushed
stone.

STEP 5 - Petitioner's exclusive .060 ml high grade Rigid Sealer (fiberglass sheeting) is permanently
riveted over the crack (minimum 2 feet wide) and extends below the floor to the footer. This material
is guaranteed never to deteriorate or to transmit water, dampness or musty odors.
STEP 6 - The floor opening is then carefully recemented to the wall/rigid sealer.
STEP 7 - The debris in the immediate work area is immediately removed and is swept clean.
In the case of a general overall condition of walls leaking, drainboard alone is installed on
the walls to divert water to below the floor and Steps 3 and 4 above would not apply. All other steps
in the process are the same. In both cases, the existing drain pipes under the floor may be used for
connecting drainage if they are functioning, or Petitioner installs new drainage.
Petitioner's wall drainage system is unconditionally guaranteed for the life of the house
(subject to existing drain tile functioning).
Section 1101 of the Tax Law states, in part:
Definitions ....
(b) When used in this article for purposes of the taxes imposed by subdivisions ... (c)
... of section eleven hundred five and by section eleven hundred ten, the following
terms shall mean:
*
*
*
(4) Retail sale. (i) A sale of tangible personal property to any person for any purpose,
other than (A) for resale as such or as a physical component part of tangible personal
property, or (B) for use by that person in performing the services subject to tax under
paragraphs ... (3),(5) ... of subdivision (c) of section eleven hundred five where the
property so sold becomes a physical component part of the property upon which the
services are performed or where the property so sold is later actually transferred to
the purchaser of the service in conjunction with the performance of the service
subject to tax. Notwithstanding the preceding provisions of this subparagraph, a sale
of any tangible personal property to a contractor, subcontractor or repairman for use
or consumption in erecting structures or buildings, or building on, or otherwise
adding to, altering, improving, maintaining, servicing or repairing real property,
property or land,.., is deemed to be a retail sale regardless of whether the tangible
personal property is to be resold as such before it is so used or consumed, ....
Section 1105(c)(3) of the Tax Law imposes a tax on the receipts from the service of
"[i]nstalling tangible personal property ... or maintaining, servicing or repairing tangible personal
property."

Section 1105(c)(3)(iii) provides an exception from tax when "installing property which, when
installed, will constitute an addition or capital improvement to real property, property or land, as the
terms real property, property or land are defined in the real property tax law as such term capital
improvement is defined in paragraph nine of subdivision (b) of section eleven hundred one of this
chapter .... "
Section 1105(c)(5) of the Tax Law imposes tax upon the receipts from the service of
"[m]aintaining, servicing or repairing real property, property or land.., as distinguished from adding
to or improving such real property, property or land, by a capital improvement."
Section 1115 of the Tax Law provides in part:
Exemptions from sales and use taxes.--(a) Receipts from the following shall be
exempt from the tax on retail sales imposed under subdivision (a) of section eleven
hundred five and the compensating use tax imposed under section eleven hundred
ten:
*

*

*

(17) Tangible personal property sold by a contractor, subcontractor or repairman to
a person other than an organization described in subdivision (a) of section eleven
hundred sixteen, for whom he is adding to, or improving real property, property or
land by a capital improvement, or for whom he is about to do any of the foregoing,
if such tangible personal property is to become an integral component part of such
structure, building or real property; provided, however, that if such sale is made
pursuant to a contract irrevocably entered into before September first, nineteen
hundred sixty-nine, no exemption shall exist under this paragraph.
Section 527.7(a)(1) of the Sales and Use Tax Regulations provides in part:
Maintaining, servicing and repairing are terms which are used to cover all activities
that relate to keeping real property in a condition of fitness, efficiency, readiness or
safety or restoring it to such condition. Among the services included are services on
a building itself such as painting; services to the grounds, such as lawn services, tree
removal and spraying; trash and garbage removal and sewerage service and snow
removal.
In order to qualify for the exception from sales tax provided by section ll05(c)(3)(iii) of the
Tax Law, it must be established that the installation of the property will result in an addition or
alteration to real property that meets the requirements of a capital improvement as defined in section
l101(b)(9) of the Tax Law.

Section l101(b)(9)(i) of the Tax Law defines "capital improvement" as:
An addition or alteration to real property which:
(A) Substantially adds to the value of the real property, or appreciably prolongs the
useful life of the real property; and
(B) Becomes part of the real property or is permanently affixed to the real property
so that removal would cause material damage to the property or article itself; and
(C) Is intended to become a permanent installation.
Section 527.7(b)(4) of the Sales and Use Tax Regulations provides additional guidance when
determining whether an activity is taxable:
The imposition of tax on services performed on real property depends on the end
result of such service. If the end result of the services is the repair or maintenance
of real property, such services are taxable. If the end result of the same service is a
capital improvement to real property, such services are not taxable. (Emphasis
added.)
In this case it must be ascertained whether the waterproofing system installed by the
Petitioner meets the criteria set forth by the Tax Law and regulations for an affirmative capital
improvement determination.
In the Matter of F. W. Woolworth, Det Tax App Trib, December 1, 1994, TSB-D-94(46)S,
the Tribunal in affirming the Administrative Law Judge's determination quoted the following
language from that determination:
[w]hat sets apart repair activities which involve merely keeping real property in a
condition of fitness, efficiency, safety or restoring it to such condition from activities
which constitute a capital improvement, is the three-prong test of whether such
improvement substantially adds to the value of the real property, becomes part of the
real property such that removal would cause material damage, and whether the same
is intended to become a permanent installation. The capital improvement criteria
include by their very nature the repair and maintenance functions, i.e., a contractor
is both repairing the real property and maintaining it while engaged in the process of
doing something of a more permanent nature. Whether the individual facets of the
work performed by Brisk in this case go beyond the maintenance point and rise to the
level of a capital improvement depends upon the framework in which they are
viewed, and the result of the application of the three-prong test. As additional
guidance we are afforded the "end result" test (Determination, conclusion of law
"G").

Applying this rationale, Petitioner's waterproofing system as described in this case, does:

1. Substantially add to the value of the real property or appreciably prolong the useful life of
   the real property, by eliminating the flow of water onto the basement floor and eliminating the cause
   of mildew and rot to the basement furnishings, walls and ceiling supports;
2. Become part of the real property or is permanently affixed to the real property so that
   removal would cause material damage to the property. The wall drainage system is permanently
   attached to the wall, with rivets, and the portion below the floor level cemented tight (when the
   concrete floor is closed after verification that the floor drainage system is in place and working); and
3. Become a permanent installation. The homeowner is seeking to eliminate permanently the
   flow of water onto the basement floor though the installation of the wall drainage system. Petitioner
   guarantees the wall drainage system for the life of the house.
   Based upon the above analysis, Petitioner's particular method of waterproofing described
   above will constitute a capital improvement to real property. Labor and materials furnished to
   Petitioner's customers will be exempt from sales tax pursuant to Sections ll05(c)(3)(iii) and
   1115(a)(17) of the Tax Law. Petitioner should obtain a properly completed Capital Improvement
   Certificate from its customers to document its exempt sales. Petitioner must pay sales or
   compensating use tax on its purchase of materials used to perform the capital improvement. See Tax
   Law, section l101(b)(4).
