Accelerated depreciation is the right to deduct faster, against IRPJ and CSLL, the wear of fixed assets used intensively or favoured by law. Instead of the tax authority’s standard rate — a vehicle at 20% a year, say — a company under Brazil’s Lucro Real (actual-profit) regime can apply higher coefficients (1.5 for two shifts and 2.0 for three, under art. 323 of the Income Tax Regulation, RIR/2018) or regimes that allow 50% to 100% of the asset to be written off in the first year. The effect is to bring the deductible expense forward, cut the period’s tax and generate cash. And a company that failed to claim a benefit it was entitled to may, in principle, review the past five years — a thesis that requires evidence, as detailed below.
- Three ways to accelerate: by shifts (art. 323 — movable assets, coefficients 1.5 and 2.0); incentivised (special regimes, with an exclusion in LALUR Part B); and in rural activity (art. 6 of Provisional Measure 2,159-70/2001 — 100% in the year of acquisition).
- The gain is cash and scales by sector: acceleration brings the deduction forward but does not increase the total (the accumulated amount never exceeds cost — art. 317, § 3). In Lucro Real, the marginal IRPJ + CSLL rate reaches ~34%.
- Beyond income tax: fixed assets also generate a PIS/Cofins credit; and the regime matters — under Lucro Presumido depreciation is not deductible.
- Recovering the overpaid: the tax return can be amended for up to five years, but retroactive recovery is a contested thesis — the safe route is prospective, from the current year.
Below, the TaxUp team details what it is, the difference between tax and book depreciation, the three ways to accelerate, how much it is worth by sector with numbers, how to recover five years, the proof that avoids disallowance, the points usually missed, the legal limits and what CARF decides. For the “battery” asset — electric fleets, BESS, rental — there is a specific deep dive in battery depreciation.
What accelerated depreciation is
Every fixed asset loses value through use, the passage of time and obsolescence. Income-tax law lets that loss become a deductible expense: depreciation (art. 317 of RIR/2018). For a company under Lucro Real, every real of depreciation reduces the IRPJ and CSLL base.
The tax authority publishes a table of annual rates that assumes normal use, in a single eight-hour shift a day (Annex III of IN RFB 1,700/2017):
| Asset | Annual rate (normal use) | Tax useful life |
|---|---|---|
| Buildings | 4% | 25 years |
| Machinery and equipment | 10% | 10 years |
| Installations | 10% | 10 years |
| Furniture and fixtures | 10% | 10 years |
| Passenger vehicles | 20% | 5 years |
| Computers and peripherals | 20% | 5 years |
Accelerated depreciation is the legal exception to that table. It recognises that an asset used intensively — or one the law wants to encourage — wears out before the “average” term and may be deducted faster. It is not a manoeuvre: it is a statutory right, and art. 320, § 1 of RIR/2018 assures the taxpayer the quota “effectively suited to the depreciation conditions of its assets”, provided it furnishes proof when adopting a rate other than the table’s.
Tax depreciation vs book depreciation
Book depreciation follows CPC 27 and reflects the real consumption of the asset; tax depreciation follows the RIR and the authority’s rates. Where book is lower than tax, the difference is excluded from taxable profit (art. 321 of RIR/2018); where it exceeds the limit, it is added back. This control is kept in Part B of the tax ledger (e-LALUR), linked to the annual return (ECF).
The three ways to accelerate depreciation
There are three routes to depreciate faster in Brazil. They have different legal bases and requirements and, in some cases, can be combined.
1. Shift-based accelerated depreciation (art. 323 of RIR/2018)
It is the broadest and most under-used. For movable assets, the law multiplies the normal rate by a coefficient that grows with the number of daily operating shifts (art. 323, originating in art. 69 of Law 3,470/1958): one eight-hour shift, 1.0; two eight-hour shifts, 1.5; and three eight-hour shifts, 2.0.
| Operating regime | Coefficient | Effect on a vehicle (normal rate 20%) |
|---|---|---|
| One eight-hour shift | 1.0 | 20% a year — 5 years |
| Two eight-hour shifts | 1.5 | 30% a year — ~3.3 years |
| Three eight-hour shifts | 2.0 | 40% a year — 2.5 years |
A fleet running two shifts, a 24-hour production line, servers that never stop: all qualify. The weak point — where audits focus — is the proof of the operating regime. CARF has accepted varied evidence (Ruling 105-15.493) and upholds disallowance when it is missing (Ruling 1002-004.198).
2. Incentivised accelerated depreciation (special regimes)
Here the acceleration comes not from use but from an incentive policy, booked as an exclusion in LALUR Part B. The most recent example was Law 14,871/2024, which allowed depreciating up to 50% in the year of installation and up to 50% the following year for new machinery and equipment in defined sectors; the acquisition window ran until 31 December 2025 and has closed. There is also full depreciation, in the year of acquisition, of new assets for research and innovation (the “Lei do Bem”, art. 17, III of Law 11,196/2005).
3. Accelerated depreciation in rural activity (100% in the year)
It is the most generous regime. Fixed assets acquired by a rural legal entity for use in the activity — machinery, tractors, implements, except bare land — may be depreciated fully in the year of acquisition (art. 6 of Provisional Measure 2,159-70/2001), as an exclusion in LALUR. CARF has favoured the vertically integrated agribusiness (Ruling 1101-001.476). (Ruling numbers via the Inspira database; check the full text.)
How much it is worth: the benefit is cash
Accelerated depreciation does not increase the total deducted: art. 317, § 3 of RIR/2018 sets that the accumulated quotas may not exceed the acquisition cost. What changes is the timing — the deduction comes earlier, and bringing a deduction forward means bringing cash forward.
For a company under Lucro Real, IRPJ (15% plus a 10% surtax) and CSLL (9%) add up to a marginal rate of about 34% on the depreciation expense. Bringing that deduction into the early years cuts tax now and frees capital — a present-value effect that grows with the company’s cost of capital.
“A BRL 5 million fleet depreciated at 20% a year generates BRL 1 million of expense per year (BRL 340,000 of annual IRPJ/CSLL saving). With three proven shifts, the rate goes to 40%: the expense jumps to BRL 2 million in the early years, doubling the initial saving.”
TaxUp · Tax Practice
No surprise that accelerated depreciation is a classic policy tool: Eichfelder and Schneider (2018, working paper) on Germany’s bonus depreciation linked the incentive to higher business investment.
How much it is worth, in practice: cases by sector
To leave the abstract, four illustrative scenarios. The base formula: saving = (accelerated deduction − straight-line deduction) × 34%.
Manufacturing — a three-shift production line
A plant with BRL 20 million in machinery (10% a year) running 24 hours. Under the 2.0 coefficient (art. 323), the rate goes to 20%: the annual deduction rises from BRL 2 million to BRL 4 million — BRL 2 million more, ~BRL 680,000 of IRPJ/CSLL brought forward each year, backed by proof of the three shifts.
Transport and logistics — a two-shift fleet
A carrier with BRL 10 million in vehicles (20%) running two shifts. The 1.5 coefficient takes the rate to 30%: the deduction goes from BRL 2 million to BRL 3 million — BRL 1 million more, ~BRL 340,000 of tax brought forward a year.
Agribusiness — 100% rural depreciation
A rural legal entity with BRL 8 million in tractors and implements may, under PM 2,159-70/2001, deduct 100% in the year of acquisition — BRL 8 million of deduction at once (~BRL 2.7 million of tax), against BRL 1.6 million a year on the table.
Technology and data centres — 24-hour equipment
A data centre with BRL 5 million in servers (20%) running continuously. Under the 2.0 coefficient, the rate goes to 40%: the deduction doubles from BRL 1 million to BRL 2 million — ~BRL 340,000 of tax brought forward a year.
| Sector (illustrative) | Lever | Extra deduction in year 1 | Tax brought forward (~34%) |
|---|---|---|---|
| Manufacturing — BRL 20m machinery, 3 shifts | Shifts (2.0) | ~BRL 2.0m | ~BRL 680k/year |
| Transport — BRL 10m vehicles, 2 shifts | Shifts (1.5) | ~BRL 1.0m | ~BRL 340k/year |
| Agribusiness — BRL 8m machinery | Rural (100% in year) | ~BRL 6.4m | ~BRL 2.7m (in the year) |
| Data centre — BRL 5m servers, 24h | Shifts (2.0) | ~BRL 1.0m | ~BRL 340k/year |
How to recover what was overpaid (and the size of the risk)
If a company was entitled to depreciate faster and applied only the normal rate, it deducted less than it could and, in principle, overpaid IRPJ and CSLL. The mechanics exist: the ECF can be amended for up to five years (with the DCTF), generating a negative balance recoverable via PER/DCOMP.
The proof that separates the thesis from an assessment
Shift-based accelerated depreciation lives or dies by the proof of the operating regime. Accepted means include:
- Working-time records for operators (time cards, shift rosters);
- Daily output compared with the machine’s one-shift capacity;
- Electricity consumption consistent with multi-shift operation;
- Production orders, equipment logs and fleet telemetry.
For a shorter useful life (rather than the shift regime), the route is a report by an official research body (the INT or equivalent), under art. 320, §§ 1 and 2. Building the evidence before applying the coefficient — not after the audit notice — is what makes the saving definitive.
What the law does not allow (the limits that avoid an assessment)
Knowing the boundaries is part of the benefit’s safety:
- Only movable assets in shift acceleration — real estate and installations are out (Rulings 3301-012.728 and 729).
- Land is not depreciated (art. 318 of RIR/2018) — and, in rural activity, neither is bare land.
- Assets that appreciate (artworks) and assets subject to depletion or amortisation are out (art. 318).
- Cost cap: accumulated depreciation may not exceed the acquisition cost (art. 317, § 3).
- LALUR Part B control is mandatory in incentivised and rural depreciation.
Points usually missed
Replacing parts and components (repair vs improvement)
Under RIR/2018 (art. 354, § 2), repairs or replacements of parts that increase the asset’s useful life by more than one year are capitalised and depreciated; spending that merely keeps the asset running is an expense of the period. Treating an improvement as a current cost (or vice versa) is a classic source of disallowance — and of lost deductions.
Leasing
In accounting, under IFRS 16/CPC 06 (R2), the lessee recognises a right-of-use asset and depreciates it in virtually all leases (the operating-vs-finance distinction survives only for the lessor). For tax, however, that depreciation is neutralised: the lessee deducts the lease payments, not the asset’s depreciation (Law 12,973/2014, Articles 47 to 49). Where accelerated depreciation actually appears depends on the contract structure.
PIS/Cofins credit on the asset
In the non-cumulative regime (Lucro Real), machinery and equipment in fixed assets also generate a PIS/Cofins credit, taken by depreciation charges, in 1/48 per month, or immediately for new production assets (Law 10,833/2003, art. 3; Law 11,774/2008). When the credit is computed by depreciation, a shorter useful life brings it forward — an extra front of credit recovery.
Lucro Real vs Lucro Presumido
The whole thesis lives in Lucro Real, where depreciation is deductible. Under Lucro Presumido, the base is a presumed margin on revenue — depreciation does not reduce the tax. Asset-intensive companies should check whether Lucro Real is, for that reason, the more advantageous regime.
What CARF decides on accelerated depreciation
A snapshot of the administrative case law (via the Inspira database; check the full text of each ruling):
| CARF ruling | What it decided | Reading |
|---|---|---|
| 105-15.493 | Two proven shifts → coefficient 1.5 (30% a year), even without a report | Favourable |
| 108-08.265 | 24-hour operation at a toll-road concessionaire → coefficient applicable | Favourable |
| 1201-001.862 | “Mixed-use” agricultural machinery in agribusiness → rural benefit | Favourable |
| 1101-001.476 | Vertically integrated sugar-cane agribusiness → rural depreciation (PM 2,159-70) | Favourable |
| 1002-004.198 | Disallowance of the 2.0 coefficient for lack of proof of three shifts | Risk / proof |
| 3301-012.728 and 729 | Shift-based accelerated depreciation only for movable assets | Limit |
The message is consistent: the benefit is solid when the classification and the proof are in place; it is fragile when stretched beyond the legal hypothesis.
How TaxUp conducts the work
The work starts from a survey of the fixed assets and a reading of each asset’s use regime, separating what can be accelerated by shifts, what fits a current incentive and what is rural. Then it builds the evidence, reviews the PIS/Cofins credit on fixed assets, adjusts the depreciation policy going forward and, where there is supporting evidence, assesses reviewing the open years. It is the combination of tax planning with recovery of credits — relevant to manufacturing, agribusiness and technology.
“Accelerated depreciation cuts tax today and, where there is evidence, lets you discuss what was overpaid yesterday. What decides the outcome is not the thesis, it is the proof: a documented regime, the right classification and control in LALUR.”

Frequently asked questions
What is accelerated depreciation?
It is the right to deduct faster, against IRPJ and CSLL, the wear of fixed assets used intensively or favoured by law. Instead of the authority’s normal rate, a higher coefficient (by shifts) or a regime allowing 50% to 100% in the early years applies.
What are the shift coefficients?
Under art. 323 of RIR/2018, for movable assets: 1.0 for one eight-hour shift, 1.5 for two and 2.0 for three. The coefficient multiplies the asset’s normal rate — a vehicle at 20% a year goes to 30% or 40%.
Do I need a report to accelerate by shifts?
Not necessarily. Shift acceleration (art. 323) requires proof of the operating regime (rosters, telemetry, energy use), not a report. The official-body report (INT) is the route to prove a shorter useful life (art. 320, §§ 1 and 2) — distinct grounds that can be combined.
Does accelerated depreciation increase the total tax saved or only bring it forward?
As a rule, it brings it forward. Accumulated depreciation cannot exceed the asset’s cost (art. 317, § 3), so the gain is cash flow. In rural depreciation and some incentives, the front-loading reaches 100% in the first year.
Does a company under Lucro Presumido benefit from this?
No. Under Lucro Presumido the tax falls on a presumed margin of revenue, and depreciation is not deductible. The benefit — and the PIS/Cofins credit on fixed assets — is exclusive to Lucro Real.
Can I recover depreciation I failed to claim?
It is a thesis, with risk — not an automatic right. Because depreciation is an expense of its accrual period, retroactive recovery via an amended return is contested (CARF tends to refuse it), and the negative balance may be denied, with an isolated penalty. The safe route is prospective: adjusting the rate from the current year.
Does shift-based accelerated depreciation apply to real estate?
No. CARF held that shift acceleration reaches only movable assets, not real estate or installations. Buildings follow the normal rate (4% a year).
Is replacing a part an expense or a new asset?
It depends. Under art. 354, § 2 of RIR/2018, a replacement that increases the asset’s useful life by more than one year is capitalised and depreciated; spending that merely keeps the asset running is an expense of the period.
