71## Section 2 -- Required inputs and refusal catalogue
72 
73### Required inputs
74 
75**Minimum viable** -- bank statement for the tax year in CSV, PDF, or pasted text. Must cover 1 January to 31 December. Acceptable from any Swedish bank: Handelsbanken, SEB, Swedbank, Nordea, Danske Bank, Länsförsäkringar, Skandiabanken, or fintech banks (Revolut, Wise, N26).
76 
77**Recommended** -- sales invoices for the year, purchase invoices for any expense above SEK 10,000, municipality of residence, NE-bilaga from prior year (for loss carry-forward and räntefördelning basis).

80 
81**Refusal policy if minimum is missing -- SOFT WARN.** If no bank statement is available at all, hard stop. If bank statement only without invoices, proceed but record in the reviewer brief: "This NE-bilaga was produced from bank statement alone. The reviewer must verify that expense classifications are correct and that capital items have been properly identified."
82 
83### Refusal catalogue
84 
85**R-SE-1 -- Aktiebolag (AB) instead of enskild firma.** *Trigger:* client operates through an AB (limited company). *Message:* "This skill covers enskild firma (sole proprietorship) only. AB taxation follows the corporate income tax rules (22% bolagsskatt) and different filing forms. Please use a separate skill or consult an auktoriserad revisor."
86 
87**R-SE-2 -- 3:12 rules (fåmansbolag).** *Trigger:* client has a closely held company and asks about dividend taxation under 3:12 rules. *Message:* "The 3:12 rules for fåmansbolag are outside the scope of this skill. Please consult an auktoriserad revisor."

94 
95## Section 3 -- Transaction pattern library (the lookup table)
96 
97This is the deterministic pre-classifier for income tax purposes. When a transaction's counterparty matches a pattern in this table, apply the treatment directly. Do not second-guess. If none match, fall through to Tier 1 rules in Section 5.
98 
99**How to read this table.** Match by case-insensitive substring on the counterparty name as it appears in the bank statement. If multiple patterns match, use the most specific.

230## Section 4 -- Worked examples
231 
232These are four fully worked income tax classifications drawn from a hypothetical Swedish enskild firma IT consultant.
233 
234### Example 1 -- SaaS subscription (reverse charge moms interaction)
235 
236**Input line:**
237`2025-03-15 ; GOOGLE IRELAND LIMITED ; DEBIT ; Google Workspace ; -1,200.00 SEK`
238 
239**Reasoning:**
240Google Ireland Ltd is an EU entity (Section 3.5). The consultant is momsregistrerad. Reverse charge moms applies -- the consultant reports output moms and claims input moms on the momsdeklaration (net zero). For income tax purposes, the expense is deductible at the net amount (SEK 1,200). Moms is NOT included in R1 revenue or expense costs.
241 
242**Classification:** Deductible business expense, R3--R6 (software/IT). Amount: SEK 1,200.
243 
244### Example 2 -- Capital equipment above threshold
245 
246**Input line:**
247`2025-06-20 ; ELGIGANTEN ; DEBIT ; MacBook Pro 14" ; -22,990.00 SEK`
248 
249**Reasoning:**
250SEK 22,990 exceeds half prisbasbelopp (approximately SEK 5,000 in 2025) and the asset has a useful life over 3 years. Must enter the inventarier pool as a capital asset. Not directly expensed. Depreciation year 1 = 30% of SEK 22,990 = SEK 6,897 (räkenskapsenlig avskrivning).
251 
252**Classification:** Capital asset (inventarier pool). R7 depreciation = SEK 6,897. Do NOT put SEK 22,990 in R3--R6.
253 
254### Example 3 -- External restaurant meal (not deductible)
255 
256**Input line:**
257`2025-09-10 ; RESTAURANG PELIKAN STOCKHOLM ; DEBIT ; Client dinner ; -2,400.00 SEK`
258 
259**Reasoning:**
260External representation food costs are NOT deductible for income tax in Sweden. Only simpler refreshments (enklare förtäring) at internal events are deductible up to SEK 300/person. This is a client dinner -- zero deduction regardless of business purpose.
261 
262**Classification:** NOT deductible. Exclude from R3--R6 expenses entirely.
263 
264### Example 4 -- Home office standard deduction
265 
266**Input line:**
267(No single bank line -- client claims home office)
268 
269**Reasoning:**
270The client can choose either the standard deduction of SEK 2,000/year or actual costs proportional to floor area. Cannot combine both. If actual costs exceed SEK 2,000 and the client has a dedicated room, actual method may be better but requires documentation.
271 
272**Classification:** R3--R6 expense, SEK 2,000 (standard deduction). Flag for reviewer if actual costs are claimed instead.
273 
274---
275 
276## Section 5 -- Tier 1 rules (deterministic)
277 
278### 5.1 Kommunalskatt computation
279 
280Applied to taxable earned income (beskattningsbar förvärvsinkomst) at the municipality rate. If municipality unknown, use 32.41%. Range: 28.98% (Österåker) to 35.30% (Degerfors). **Legislation:** IL kap. 65.
281 
282### 5.2 Egenavgifter and schablonavdrag
283 
284Egenavgifter = 28.97% of net business profit (10.21% for age 66+). Since egenavgifter are calculated on the profit they reduce, apply schablonavdrag of 25% as preliminary deduction from net business profit. Actual egenavgifter reconciled on the return. **Legislation:** SAL.
285 
286**Computation:** (1) Net profit before egenavgifter = X. (2) Schablonavdrag = X x 25% = Y. (3) Taxable business income = X - Y. (4) Actual egenavgifter computed on final adjusted base.
287 
288### 5.3 Statlig inkomstskatt
289 
29020% on taxable earned income above SEK 625,800 (under 66) or SEK 733,200 (66+). Below the brytpunkt: 0% state tax. **Legislation:** IL kap. 65.
291 
292### 5.4 Grundavdrag
293 
294Income-dependent basic deduction. Minimum SEK 17,300, maximum SEK 45,300 (under 66); up to SEK 86,500 (66+). Computed automatically by Skatteverket. Reduces taxable earned income before both kommunalskatt and statlig skatt. **Legislation:** IL kap. 63.
295 
296### 5.5 Capital expenditure threshold
297 
298Assets above half prisbasbelopp (approximately SEK 5,000) with useful life over 3 years: must enter inventarier pool and depreciate. Assets below or with life under 3 years: expense immediately (direktavdrag). **Legislation:** IL kap. 18.
299 
300### 5.6 Depreciation rates
301 
302Inventarier (machinery, equipment): 30% declining balance (räkenskapsenlig avskrivning) or 20% straight-line (supplementary rule). Buildings: 2--5% straight-line. Goodwill: pooled with inventarier at 30%. **Legislation:** IL kap. 18, 19, 20.
303 
304### 5.7 Motor vehicle standard rate
305 
306SEK 25.00/mil (2025) for business travel using a private car. Alternative: actual costs with logbook apportionment. **Legislation:** IL kap. 16.
307 
308### 5.8 Home office deduction
309 
310Standard deduction: SEK 2,000/year (no documentation required). Alternative: actual proportional costs (requires floor area calculation and dedicated room). Cannot combine both methods. **Legislation:** IL kap. 16.
311 
312### 5.9 Representation
313 
314Internal: up to SEK 300/person/event for enklare förtäring. External: food costs NOT deductible for income tax (even if limited moms deduction applies). **Legislation:** IL kap. 16.
315 
316### 5.10 Moms interaction
317 
318Moms collected on sales: NOT income (exclude from R1). Input moms recovered: NOT an expense (exclude from costs). Non-deductible moms (e.g., representation): IS an expense. Non-momsregistrerad (under SEK 80,000 turnover): no moms separation needed, gross = net. **Legislation:** ML.
319 
320### 5.11 F-skatt
321 
322All self-employed must register for F-skatt. Monthly instalments due 12th of each month. Without F-skatt, clients paying the individual must pay arbetsgivaravgifter. **Legislation:** SFL kap. 55.
323 
324### 5.12 Loss carry-forward
325 
326Business losses (underskudd) carry forward to future years within the same income category (näringsverksamhet). No time limit on carry-forward. **Legislation:** IL kap. 40.
327 
328### 5.13 Record keeping
329 
330Minimum retention: 7 years from end of calendar year. Must follow god redovisningssed. Digital or paper permitted. **Legislation:** BFL.
331

333 
334## Section 6 -- Tier 2 catalogue (reviewer judgement required)
335 
336### 6.1 Jobbskatteavdrag computation
337 
338*Why ambiguous:* Complex formula based on earned income, kommunalskatt rate, and age. *Default:* Do not compute manually -- flag for reviewer or use Skatteverket's calculator. *Question:* "What is your municipality of residence? (Required for precise jobbskatteavdrag.)"
339 
340### 6.2 Expansionsfond allocation
341 
342*Why ambiguous:* Requires accurate kapitalunderlag using SKV 2196. 20.6% tax on allocation, deferred until reversal.

If so, provide your net business assets (kapitalunderlag) calculation."
343 
344### 6.3 Räntefördelning
345 
346*Why ambiguous:* Positive räntefördelning reclassifies business income as capital income (30% tax). Requires net business assets > SEK 50,000. Rate: 2.96% (statslåneräntan + 6pp). *Default:* Do not apply without reviewer confirmation. *Question:* "What were your net business assets at the start of the income year?"
347 
348### 6.4 Mixed-use phone/internet
349 
350*Why insufficient:* Business proportion unknown from bank statement alone. *Default:* 0% business use. *Question:* "Is this a dedicated business line or mixed-use? What percentage is business?"
351 
352### 6.5 Motor vehicle documentation
353 
354*Why insufficient:* Business km unknown. *Default:* Use standard rate SEK 25.00/mil only with documented business km. *Question:* "Do you have a logbook showing business vs private km?"
355 
356### 6.6 Home office -- actual vs standard
357 
358*Why ambiguous:* Choice of method affects deduction amount. *Default:* SEK 2,000 standard deduction. *Question:* "Do you have a dedicated room exclusively for business? What is its proportion of total floor area?"
359 
360### 6.7 Negative räntefördelning
361 
362*Why ambiguous:* Mandatory if business capital deficit exceeds SEK 500,000 change during year. Reclassifies capital income as business income. *Default:* Flag for reviewer. *Question:* "Has your business capital changed by more than SEK 500,000 during the year?"

409## Section 8 -- Bank statement reading guide
410 
411**CSV format conventions.** Handelsbanken exports use semicolon delimiters with YYYY-MM-DD dates. SEB exports use comma or tab delimiters. Swedbank exports typically use semicolons with DD/MM/YYYY dates -- confirm format. Common columns: Datum (Date), Text (Description), Belopp (Amount), Saldo (Balance).
412 
413**Swedish language variants.** Common descriptions: lön (salary), hyra (rent), ränta (interest), avgift (fee), köp (purchase), insättning (deposit), uttag (withdrawal), överföring (transfer), faktura (invoice), betalning (payment).
414 
415**Internal transfers and exclusions.** Own-account transfers between the client's Handelsbanken, SEB, Swedbank accounts. Labelled "egen överföring", "överföring mellan konton", "sparande". Always exclude.
416 
417**Moms interaction.** If client is momsregistrerad, bank statement amounts include moms. For income tax, expenses should be recorded net of recoverable moms. If moms is not recoverable (blocked categories), include gross amount.
418 
419**F-skatt payments.** Monthly payments to Skatteverket labelled "F-skatt" or "skattekonto". These are tax payments, NOT business expenses. Always exclude.
420 
421**Egenavgifter.** Self-employment contributions are not visible as separate bank transactions -- they are computed on the return. Do not look for them in the bank statement.
422 
423**Foreign currency.** Convert to SEK at the transaction date rate. Use Riksbanken's daily exchange rates.
424 
425**Cryptic card purchases.** Swedish bank statements often show merchant category codes or abbreviated names. If the counterparty cannot be identified, ask the client.
