Em dashes (—) and en dashes (–) had spread across comments, docs, tests, and a few UI strings, reading as AI-generated boilerplate rather than house style. Replaced each with punctuation matching its context: colon for explanatory clauses, comma for asides, plain hyphen for numeric/legal ranges (e.g. "21-23§"), "to"/"till" for date ranges, parentheses for paired-dash asides. messages/en.json and messages/sv.json were fixed by hand together to keep sv/en in sync. Left untouched where the dash is the functional subject rather than decorative punctuation: date-range-parser.ts's separator regex, charset-repair.ts's CP1252 byte-mapping table (and its test), the SIE encoding mojibake docs, generic-csv.ts's minus-sign normalizer, the agent system-prompt files that already instruct against em dashes, and a golden iXBRL test fixture compared byte-for-byte. Also fixes two bugs surfaced along the way: an off-by-one in ApiKeysPanel's scope-label split (a leftover from an earlier partial pass), and a charset-repair test that had lost the literal en-dash it exists to verify. Regenerated the agent atom seed migration (skills:generate) since 27 SKILL.md files changed. Added a CLAUDE.md rule against em/en dashes, with an explicit carve-out for the functional-dash cases above. Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com>

Core rates and rules (always in context)
Arbetsgivaravgifter: 31.42%
Total rate unchanged since 2009. Calculated on full gross salary + taxable benefits with no cap. Age tiers:
| Birth year condition | Rate |
|---|---|
| Born 1937 or earlier | 0% |
| Turned 66+ at year start (67+ from 2026) | 10.21% (only ålderspensionsavgift) |
| Standard (all others) | 31.42% |
| Temporary youth (Apr 2026 to Sep 2027) | 20.81% on salary up to 25,000 SEK/month. Eligible: vid årets ingång fyllt 18, inte 23 (i.e. age 18-22 at Jan 1; born 2003-2007 in 2026, 2004-2008 in 2027). NOT during-year age: Skatteverket rejects 23-year-olds at year start. Source: Prop. 2025/26:66 |
No avgifter required if total annual compensation from one employer < 1,000 SEK.
AGI filing deadline
12th of month following pay period (17th in Jan/Aug for turnover ≤40 MSEK). Late = 625 SEK first offense, 1,250 SEK if repeated.
Skatteavdrag lookup chain
kommun → total skattesats → round to table number (29-42) → select column (1-6 by employee category) → look up gross salary bracket → withholding amount. Sidoinkomst: flat 30%.
Semesterlön
Procentregeln: 12% of semesterlönegrundande income. Sammalöneregeln: regular pay + 0.43% semestertillägg per day (many CBAs use 0.8%). Intjänandeår: Apr 1 - Mar 31 by law (often calendar year via CBA).
Sjuklön (day 1-14)
Karensavdrag = 20% of one week's sjuklön (80% of weekly pay). Day 2-14: 80% of lost pay. Läkarintyg from day 8. Återinsjuknande within 5 days = same period continues.
Traktamente (domestic)
2024-2025: 290 SEK/hel dag. 2026: 300 SEK/hel dag. Halv dag = 50%. After 3 months same location: 70%. After 2 years: 50%.

A-skatt: withhold tax + pay avgifter. F-skatt: neither. FA-skatt: split. No F-skatt stated: withhold 30% + full avgifter. Verify via Skatteverket before first payment.
Rate update schedule
Rates shift annually with PBB, IBB, and SLR. Subscribe to Skatteverket's annual publications each December. Bilförmån formulas use SLR from November 30 of prior year (floor 0.50%). Kostförmån tied to PBB. Traktamente normalbelopp published annually.
