The tax rates that come up most
| Asset | % a year, straight line | Tax useful life |
|---|---|---|
| Buildings of concrete, brick or metal | 2 % | 50 years |
| Computer equipment | 20 % | 5 years |
| Office furniture and equipment | 10 % | 10 years |
| Cars used in the business | 10 % | 10 years |
| Goods lorries | 20 % | 5 years |
| Construction machinery and equipment | 15 % | 7 years |
| Electrical installations | 7 % | 15 years |
| Hand tools | 10 % | 10 years |
The complete table itemises hundreds of assets. The rule is simple: if the asset is itemised, its percentage is used; if not, the group's. And a different percentage can be requested from the tax authority, with justification.
The tax rules that get forgotten
-
The base is the original cost
Purchase plus transport, installation and assembly. Exchange differences from the year of purchase are added to the cost; later ones go to expense or income.
-
The first year is pro rata by months
An asset bought in September does not depreciate the whole year: it depreciates the months of use. The last year likewise.
-
No depreciation on revaluations
Even where the accounting standard allows revaluation, that part generates no deductible expense. And when the asset is sold, the revaluation does not enter the book value for calculating the gain either.
-
Mixed use, pro rata
Only the part used in the activity is depreciated. On indivisible assets — the classic case of a mixed-use vehicle — the argument with the tax authority is a common one and rarely goes your way.
-
Once a method is adopted, it is not changed
Moving from straight line to sum of the digits requires authorisation.
What should not be capitalised
With the base salary of ₡462,200 in force in 2026, the threshold is around ₡115,550. It is worth confirming the year's base salary before applying it, because it is updated by decree. And it is better to set the criterion once and apply it evenly: capitalising every chair and every keyboard adds no information and plenty of work.
And this is where deferred tax comes from
When the accounting and the tax depreciation differ, the difference is temporary: it does not disappear, it settles over the years. That is exactly what deferred tax recognises, and the tax authority itself notes that a taxpayer should apply whatever the accounting standard establishes, as long as it does not conflict with a tax rule.
Assets with their depreciation calculated
The first instalment is prorated over the months of use, as the tax rule requires, and the period's depreciation entry comes out with it.
See how it worksAbout this article. The methods, the base and the rates are in annexes 1 and 2 of the regulation to the Income Tax Act. The prohibition on deducting depreciation of revaluations, on carrying depreciation to another period, and the criterion on deferred tax, are in resolution DGT-R-029-2018. Confirm the year's base salary before applying the direct-expense threshold.
