Input line:
15/03/2025 ; DNB Innbetaling ; DESIGN STUDIO AS ; Faktura 2025-003 ; +125,000.00 ; NOK
Reasoning: Client payment. If MVA-registered (25%), NOK 125,000 includes MVA. Net = NOK 100,000 (revenue) + NOK 25,000 MVA (excluded).
Classification: Driftsinntekt = NOK 100,000. MVA NOK 25,000 excluded.
Input line:
22/04/2025 ; SpareBank 1 Kort ; RESTAURANT MAAEMO ; Kundelunsj ; -2,500.00 ; NOK
Reasoning: Representation. Deductible up to NOK 559 per person per event. If 4 persons: max NOK 559 x 4 = NOK 2,236. NOK 264 not deductible. Must document attendees and business purpose.
Classification: Deductible up to NOK 559/person limit. Flag for reviewer.
Input line:
03/06/2025 ; DNB Kort ; ELKJOP ; LAPTOP ; -18,000.00 ; NOK
Reasoning: Laptop NOK 18,000. Over NOK 15,000 and life over 3 years. Saldogruppe a (office machines, 30%). Year 1: NOK 18,000 x 30% = NOK 5,400.
Classification: Saldogruppe a. Depreciation NOK 5,400. NOT direct expense.
Input line:
15/05/2025 ; Nordea Kort ; CLAS OHLSON ; KONTORSTOL ; -4,500.00 ; NOK
Reasoning: Office chair NOK 4,500. Under NOK 15,000 threshold. Immediate full deduction.
Classification: Driftskostnad. Fully deductible.
Input line: Client claims minstefradrag NOK 104,450 on naeringsinntekt NOK 500,000.
Reasoning: INCORRECT. Minstefradrag does NOT apply to naeringsinntekt -- only to lonnsinntekt. Self-employed must deduct actual documented expenses.
Classification: REJECT minstefradrag. Use actual expenses only.
Input line: Prior year loss NOK 150,000. Current year naeringsinntekt NOK 400,000.
Reasoning: Underskudd (losses) carry forward with no time limit. Reduces alminnelig inntekt. But trinnskatt and trygdeavgift based on personinntekt (NOK 400,000) -- loss does NOT reduce personinntekt.
Classification: Alminnelig inntekt base = NOK 400,000 - NOK 150,000 = NOK 250,000. Trinnskatt/trygdeavgift on NOK 400,000.
5.6 Depreciation (Saldogrupper)

Naeringsinntekt computation
Gross revenue minus cost of sales minus operating expenses minus depreciation = naeringsinntekt. Skjermingsfradrag then reduces personinntekt (T2).
Alminnelig inntekt rule
22% flat on net income (all sources minus all deductions minus personfradrag NOK 108,550). Applies to both personal and capital income.
Trinnskatt rule
Applies to personinntekt (gross personal income less skjermingsfradrag), NOT alminnelig inntekt. Cumulative brackets.
Trygdeavgift rule
11.0% on personinntekt from naeringsinntekt. Lower threshold ~NOK 69,650.
Minstefradrag rule
Minstefradrag applies ONLY to lonnsinntekt. Self-employed must deduct actual documented expenses.
