IRS Tax Tip 2021-173, November 23, 2021

Depreciation is an annual tax deduction that allows small businesses to recover the cost or other basis of certain property over the time they use the property. It is an allowance for the wear and tear, deterioration or obsolescence of the property.

Small businesses can depreciate property when they place it in service for use in their trade or business or to produce income. The business stops depreciating property when they have fully recovered their cost or other basis or when they retire it from service, whichever happens first.

What property is depreciable?

Small businesses can depreciate machinery, equipment, buildings, vehicles, and furniture. They cannot claim depreciation on personal property. If a business uses an asset, such as a car, for business or investment and personal purposes, the business owner can depreciate only the business or investment use portion. Land is never depreciable, although buildings and certain land improvements may be.

Businesses may depreciate property that meets all these requirements. The business must:

  •  Own the property. The business is considered to own property even if it is subject to a debt.
     
  •  Use the property in a business or income-producing activity. If the property is used to produce income, the income must be taxable. Property that's used solely for personal activities can't be depreciated.
     
  • Be able to assign a determinable useful life to the property. This means that it must be something that wears out, decays, gets used up, becomes obsolete or loses its value from natural causes.
     
  • Expect the property to last more than one year. It must have a useful life that extends substantially beyond the year a business places it in service.
     
  • Not depreciate excepted property. Excepted property includes certain intangible property, certain term interests, equipment used to build capital improvements, and property placed in service and disposed of in the same year.

Small businesses should use Form 4562PDF to figure their deduction for depreciation.

Depreciation is loss in the value of property due to its use, life, wear,  tear, decay and obsolescence.

Thus depreciation is the value of building or property decreases gradually up to the utility period due to depreciation.

This depreciation is an assessment of physical wear and tear of a building and is naturally dependent on its original condition, quality of maintenance and mode of use.

Methods of calculation of Depreciation: 

  • There are different methods of calculation of depreciation.
  • Straight line method
  • Quantity surveying method
  • Constant percentage method
  • Sinking fund method

Straight line method:

Straight line method in this method is assumed to lease value by constant amount every year and thus fixed amount of original cost is written off every year, so that at the end of the term when the asset is worn out, only scrap value remains. 

Annual depreciation = ( Original cost – Scrap value ) / Life in year

D = ( C- S c ) / n

Quantity surveying method:

Quantity surveying method in the property studied in detail and extent of physical deterioration worked out in the endeavor to calculate depreciation.

Constant percentage method: 

Constant percentage method is also called a declined balanced method and this method the property is assumed to lose value annually at constant percentage of the value. 

 P = 1- ( S c/C )^ ( 1/n )

Where,

P- Percentage rate of annual depreciation.

C- Original cost

S c- Scrap value

 N- life of property in a year.

Sinking fund method:

Sinking fund method in depreciation assumed to be an annual sinking fund till that end.

 An amount of Re 1/- per annum in ‘n’ year

=  ( 1+ i ) ^n – 1 / i = (y)

DEFINITIONS

Depreciation is loss in value due to any cause. It is the difference between the market value of a structural improvement or piece of equipment and its reproduction or replacement cost as of the date of valuation. Depreciation is divided into three general categories, see below.

Physical depreciation is loss in value due to physical deterioration.

Functional or technical obsolescence is loss in value due to lack of utility or desirability of part or all of the property, inherent to the improvement or equipment.

Thus a new structure or piece of equipment may suffer obsolescence when built.

External, locational or economic obsolescence is loss in value due to causes outside the property and independent of it, and is not included in the tables.

Effective age of a property is its age as compared with other properties performing like functions. It is the actual age of the structure less the age which has been taken off by face-lifting, structural reconstruction, removal of functional inadequacies, modernization of equipment, etc. It is an age determined which reflects a true remaining life for the property, taking into account the typical life expectancy of buildings or equipment of its class and its usage. It is a matter of judgment, taking all factors, current and those anticipated in the immediate future, into consideration. Determination of effective age on older structures may best be calculated by establishing a remaining life which, subtracted from a typical life expectancy, will result in an appropriate effective age with which to work. Effective age can fluctuate year by year or remain somewhat stable in the absence of any major renewal of components or excessive deterioration.

Extended life expectancy is the increased life expectancy due to seasoning and proven ability to exist. Just as a person will have a total normal life expectancy at birth which increases as he grows older, so it is with structures and equipment.

Remaining life is the normal remaining life expectation. It is the length of time the structure may be expected to continue to perform its function economically at the date of the appraisal. This does not imply a straight-line expiration, particularly for mortgage purposes, since normal recurring maintenance and renewal of replaceable items will continue to contribute toward an extended life expectancy. This extended life process is accomplished by use of effective age as the sliding scale and not by continually lengthening the typical life expectancy as the structure ages chronologically.

Percent good equals 100% less the percentage of cost represented by depreciation. It is the present value of the structure or equipment at the time of appraisal, divided by its replacement cost.

APPROACHES TO DEPRECIATION

The simplest, and in past years a widely used accounting-type concept of depreciation, was the straight-line (age/life) approach. A life expectancy is estimated and a constant annual percentage (equal wear or serviceability each year) is taken for depreciation so that at the end of that life the depreciation equals 100% of the initial cost. This linear approach is simple and easy to use. However it does not represent reality in most cases since time is not the only factor affecting depreciation. It also fails to recognize any value-in-use. While age is a critical factor, the best approach to the physical depreciation estimate is a combination of age and condition. The observed condition of each component subject to wear is estimated relative to new condition. A major replaceable component, such as an HVAC system, can wear out quite rapidly, shortening the life expectancy before replacement, while many other portions of a structure wear out slowly, if at all, such as excavations, foundations, and concrete exterior walls. Such long-lived portions often represent a major portion of the total reproduction cost and if still functional will contribute toward an extended life expectancy. Physical depreciation cannot be considered a straight-line deduction from reproduction cost, since necessary and normal maintenance can offset, retard and even eliminate deterioration.

Another approach to depreciation is called the mid-life theory. This takes into account that most buildings depreciate little during the first few years. When it becomes evident that the buildings are no longer new, even though they are adequately maintained, the maintenance expenses rise, rentals tend to decrease and the building depreciates faster. After a number of years, they reach the period called mid-life, at which time, if the buildings are structurally sound and properly maintained, the depreciation remains constant. The mid-life theory suffers from the fact that maintenance expenses on the average building continue to go up in order to maintain the same appearance and utility. Also, at any age, certain building features may suffer from obsolescence.

These concepts lead to a third theory, the extended life concept, which starts with the hypothesis that buildings age in much the same manner as people and that the older they get, the greater is their total life expectancy. This concept recognizes that a building is in the prime of life before mid-life and that the road is downhill after that. However correction of deficiencies may lower the effective age and lengthen the remaining life. This recurring revitalization process periodically reverses a continuous progression down the effective age scale, reducing the indicated depreciation percentage as components are renewed throughout the life span of the building. This nonlinear approach accounts for a greater present value or slower depreciation rate in the early years, as compared to the later years, when diminishing serviceability and higher maintenance can accelerate depreciation.

OVERVIEW

Depreciation is an opinion of a structure’s loss in value in relation to its cost-new estimate. If all the pertinent factors are properly considered, depreciation should be reliably estimated. The overall depreciation tables in this section consider the progression of normal deterioration and functional obsolescence based on age and condition for the class and usage of the improvement. Any abnormal or excessive functional and any or all external obsolescence are considered separately and are not included in the tables.

Physical deterioration is the wearing out of the improvement through the combination of wear and tear of use, the effects of the aging process and physical decay, action of the elements, structural defects, etc. It is typically divided into two types, curable and incurable, which may be individually estimated by the component breakdown method using an age-life approach. Damage caused by accidents, vandalism, etc., may be further categorized as deferred maintenance, generally requiring immediate attention, whether curable or incurable, and treated separately based on the items’ cost to repair.

Curable physical deterioration is generally associated with individual short-lived items such as paint, floor and roof covers, hot-water heaters, etc., requiring periodic replacement or renewal, or modification continuously over the normal life span of the improvement.

Incurable physical deterioration is generally associated with the residual group of long-lived items such as floor and roof structures, mechanical supply systems and foundations. Such basic structural items are not normally replaced in a typical maintenance program and are usually incurable except through major reconstruction. The distinction here is whether or not such corrections would be justified, economically and/or practically, in view of the cost, time and value gain involved. Exceptions might be with respect to historical or landmark buildings or a component that threatens the structural integrity of the structure itself. In estimating the loss of value attributable to physical deterioration, the objective is to set up the cost of restoring the building to new condition. A new improvement, suitable for its site, requires little study to establish a reasonable estimate of accrued depreciation. However, after weathering for a few years, a structure showing signs of age, deterioration and abuse requires a more detailed analysis to determine the extent of value loss. This seasoning can be prolonged with sound, well-maintained components or rather rapid, as in the case of a building shoddily or improperly constructed of inexpensive, short-lived components that have been inadequately or poorly maintained. A detailed building examination and appraisal itemizes the component parts of a structure, and where total depreciation may be difficult to judge, the depreciation of individual components may be more logically estimated. This detailed component breakdown can then form the foundation from which the overall depreciation tables may be reasonably used once properly benchmarked.

PHYSICAL INDICATORS

When considering the extent of physical deterioration, the appraiser pays particular attention to the following indicators:

  1. Floors and Floor Coverings — Cracks, unevenness, sagging, worn finish, rough or scarred finishes, creaking or springiness underfoot, cracks in slabs at column connections and separation at expansion joints in slabs, damaged insulation or drainage.
  1. Interior Construction — Cracks in plaster, open joints in millwork, sticking doors, peeling paper or paint, scars, missing or loose hardware, smoke stains, mildew stains or the effect of prolonged dampness, rodent, insect or termite infestation, damage or decay.
  1. Mechanical Equipment — Defective wiring, broken or tarnished light fixtures, loose switches, worn, broken or stained plumbing fixtures, leaking faucets or piping connections, odors indicative of faulty sewer piping, drip pans, escaping steam, noisy radiators, rusting pipes, battered or rusted ductwork, furnaces or boilers in poor repair, mold, mildew from defective filters, air cleaners and venting, excessive soot or dust stains.
  1. Roof — Evidence of leakage, oxidized roof metal, shingles or tiles missing or split, stained interior ceilings, sagging or decaying roof structure, cracking laminated trusses, tie rods to strengthen bottom chords of timber trusses, damaged truss bracing, plugged roof drains, evidence of standing water, vibration from mechanical equipment, damaged insulation.
  1. Exterior Walls — Peeling paint, cracked or loose mortar joints, oxidized sheet metal, frame lines out-of-plumb, loose or decaying wood siding, loose ornamentation, exposed reinforcing bar at joints or in footings, unprotected or deteriorating steel framing, brick that needs painting or pointing, inoperable windows or clerestory sashes, broken or rusted screens, sticking doors, inoperable hardware. Some of the external factors affecting the extent and rate of physical deterioration are:
  1. Temperature Extremes — Extreme heat tends to dry out and warp lumber, damage roofing, cause cracks in stucco or plaster due to expansion and contraction, and oxidize paint coatings. Extreme cold with freezing down to frost line, expansion and contraction, etc., can cause similar problems.
  1. Humidity Extremes — High humidity tends to promote dry rot and insect infestation.

iii.      Weather Extremes — Heavy snow, floods, hurricanes and tornadoes obviously cause damage. Torrential rains can undermine foundations and create ponding and leaks in roof structures, which in turn may damage interior finishes. Rainstorms accompanied by high winds can damage walls, doors, flooring and mechanical building equipment.

  1. Earthquakes — Earthquakes may not only cause damage, which is apparent, but structural damage to substructures and bearing soils which may not become evident until years after the disturbance.
  1. Airborne Corrosives — Structures located near oceans are subjected to corrosive salt air, which attacks nearly every part of the structure. Buildings located in areas where large concentrations of corrosive industrial waste gases are vented into the atmosphere typically have relatively short physical lives also.

Functional obsolescence is the perceived market reaction to under- or over improvements in the utility or desirability of part or all of the improvement. This is divided into two types, curable or incurable. These are further subdivided into inadequacies or deficiencies and super adequacies or excesses. Again the test as to when an item is curable or incurable is whether the capitalized gain or value added by correcting the obsolescence by replacement, remodel, addition or removal, is equal to or greater than the cost to cure as indicated in the market.

Inadequacies are some kind of building deficiency that does not meet current market expectations. Inadequate fixtures or ceiling insulation may be curable while a poor floor plan or tandem rooms may be incurable.

Super adequacies are those unwanted items, which do not add value at least equal to their cost, notably special- or singular-purpose features for a particular user. Many super adequacies are incurable except where excess-operating costs might make it economical to remove or replace the item.

FUNCTIONAL INDICATORS

When considering the extent of functional obsolescence, the appraiser pays particular attention to the following indicators:

  1. Design characteristics — Appealing or poor or antiquated style or design, traffic and noise levels, maintenance or serviceability, security, evacuation, market

acceptance or resistance, environmentally responsible or safe, eye appeal, symmetry, scale, orientation, interaction or appropriate blend of materials, glazing, durability, colors, etc., suitable for the occupancy, distinctive motif of a singular- or special-purpose use or architectural style.

  1. Physical Layout — Suitable room layout and orderly flow, overall or room, net vs. gross space, volume, appropriate wall heights, lighting levels, natural light and ventilation, adequate support facilities, storage, counter, cabinet size and placement.
  1. Mechanical Equipment — Inadequate or excess number of poorly spaced or antiquated plumbing or electrical and lighting fixtures, HVAC, conveyance, appliances, PA systems and other equipment, service or power requirements, energy consumption or efficiency, actual vs. rated capacity or performance, abnormal operating costs, proper leak detection or emission controls, pressure differentials, technological changes, e.g., electric vs. standing pilot ignition, etc., appropriate air quality and changes.
  1. Site Assessment — Land use, size, shape, topography, access, easements or other encroachments, utilities, soil type, stability, drainage and percolation, water table and use, erosion, vegetation, land- or waterscape, view or other amenities, flood plain, wetlands, coastal, brush, seismic or fault areas, presence of hazardous contaminants (see Environmental below), etc., can all affect the structure and its setting. Some of the external factors affecting the extent of functional obsolescence are:
  2. Code Requirements — Building codes or zoning for conforming use, height, stories, area, setback, building separation, size- man ionization, energy equivalency trade-offs, etc., OSHA, Fire and Life Safety, etc. compliance (see below).
  1. Fire Protection Requirements — Proper rating, detection for life safety and security, signaling controls, communications, signage, standpipe, sprinklers, extinguishers, hydrants, vents, draft curtains, fans, pumps, door and smoke controls, standby power, emergency phones, appropriate exits, overhang, balcony and deck exposures, stairways, roofing classification, safety or double glazing.

III.           Handicapped Requirements — ADA compliance, barrier-free design, parking, ramps, automatic entry, door, hallway widths, markings, signage, alarms, service, cabinet and railing heights, drinking fountains, grab bars, exposed hot-water piping, handicap fixtures, turnaround space, elevator controls, cab size, lifts, etc.

  1. Environmental — EPA, wetlands and air quality compliance, water, soil, radon, asbestos, UREA formaldehyde foam insulation, PCBs, CFCs, high-voltage lines, halon, heavy metals or lead contamination, runoff, emissions or sediment containment, detection and testing, septic tanks, leach fields, demolition constraints, disposal or remediation. Evidence of leakage, absence of plants or animals, sick or stressed plants or animals, discolored soil or water, surface sheens and noxious odors, presence of discarded batteries, abandoned wells, sumps, tanks, barrels or other containers of fertilizer, pesticides and herbicides, paints and thinners, heating oil, petroleum or other hazardous chemical substances.
  1. Weather Extremes — Appropriate insulation levels, heat gain or loss, shading, passive or active alternatives, energy equivalency trade-offs, window treatment, glass strength, proper trusses, size, spacing, pitch and drainage for rain and snow loading, proper connections for hurricane wind forces, uplift exposure, operable shutters.
  1. Earthquakes — Appropriate bracing, connections to structural shell, shear walls, storefront facade or parapet, overhang exposure, irregular shape, framing stress, torsion, distance from other structures for pounding, etc.

External Obsolescence is a change in the value of a property, usually negative but can be an enhancement, caused by forces outside the property itself, and is not included directly in the tables that follow. It can be divided into two types, locational and economic. Locational factors are generally incurable and may affect only a small area, while economic factors can cover a wide geographic area and may be only temporary and reversible. These external forces will affect different types of property, residential or commercial, differently. For example, it is desirable or advantageous for a manufacturing plant to be situated close to a railroad spur; conversely, it is a disadvantage for a residential property to be located close to that same spur. Close proximity to a major highway is generally much more beneficial for an apartment complex than a single-family residence, etc. Any abnormal, isolated or temporary cases of external obsolescence, usually computed separately, can be measured by market abstraction and capitalization of the imputed loss or gain, which generally affects land values first, then the improvements, by changing the possible uses and altering remaining life.

EXTERNAL INDICATORS

When considering the extent of external obsolescence, the appraiser pays particular attention to the following indicators in the immediate vicinity, marketing area or community as a whole:

  1. Physical Factors — Proximity of desirable or unattractive natural or artificial features or barriers, general neighborhood maturity, conformity, deterioration, rehabilitation or static character, known cleanup sites, nuisances, graffiti, waste dump, swamp, toxic industry, electromagnetic fields, brush area, lack of view or landscaping, floodplain, dam inundation area, drainage, water table, sinkholes, seismic or fault zones, soil types, liquefaction, landslides, etc., local ecosystem, endangered species, habitat areas.
  1. Infrastructure — Highest and best use, quality, availability and source of utilities, public services, fire stations, staffed or volunteer, distance from hydrants, street improvements, traffic patterns, emergency response, evacuation routes, public transportation and shipping facilities, parking, retail, recreation, education facilities, etc.
  1. Economic — Demand-supply imbalance, saturation or monopoly, competition or alternatives, market share, industry or major plant relocation, employment development and growth patterns, utility and insurance rates, availability of funds or terms, labor and materials, interest rates, vacancy, building rates, general inflation or deflation rates, tenant ratings, length of time on market or lease up or absorption, income streams and returns, changing consumer habits, purchasing power, property association or government forces, zoning, land use, air rights, legal nonconformity, permit, taxing and assessment policies and bureaucracy or other limiting conditions or restrictions.

CONDITION RATING INDICATORS

Excellent Condition — All items that can normally be repaired or refinished have recently been corrected, such as new roofing, paint, furnace overhaul, state-of-the-art components, etc. With no functional inadequacies of any consequence and all major short-lived components in like-new condition, the overall effective age has been substantially reduced upon complete revitalization of the structure regardless of the actual chronological age.

Very Good Condition — All items well maintained, many having been overhauled and repaired as they’ve showed signs of wear, increasing the life expectancy and lowering the effective age with little deterioration or obsolescence evident with a high degree of utility.

Good Condition — No obvious maintenance required but neither is everything new. Appearance and utility are above the standard, and the overall effective age will be lower than the typical property.

Average Condition — Some evidence of deferred maintenance and normal obsolescence with age in that a few minor repairs are needed, along with some refinishing. But with all major components still functional and contributing toward an extended life expectancy, effective age and utility is standard for like properties of its class and usage.

Fair Condition (Badly Worn) — Much repair needed. Many items need refinishing or overhauling, deferred maintenance obvious, inadequate building utility and services all shortening the life expectancy and increasing the effective age.

Poor Condition (Worn Out) — Repair and overhaul needed on painted surfaces, roofing, plumbing, heating, numerous functional inadequacies, substandard utilities etc. (found only in extraordinary circumstances). Excessive deferred maintenance and abuse, limited value-in-use, approaching abandonment or major reconstruction, reuse or change in occupancy is imminent. Effective age is near the end of the scale regardless of the actual chronological age.

TYPICAL BUILDING LIVES

Typical life expectancies of single and multifamily residences are based on case studies of both actual mortality and ages at which major reconstruction had taken place. The exceptions to the studies are the typical life expectancies for modular structures and manufactured housing (mobile homes). Typical life expectancies for modular structures assume conformity to site-built residences in both quality and design. Typical life expectancies for manufactured housing represent the projected mortality of structures produced after the enactment of more stringent local and national building codes. All cases of abnormal or excessive obsolescence due to external causes outside of and not inherent to the subject properties were excluded.

These are the common principles found in all the manuals for Marshall & Swift, Boeckh, RS Means, Craftsman, Sweet, Blue Book, etc. The application of these principles apply to all cases in valuating or appraising buildings for Actual Cash Value for insurance purp
