What it does
Tax Bracket Simulator is an agent skill from revfactory/harness-100. 세율 구간별 세액을 시뮬레이션하고 절세 포인트를 식별하는 세율 구간 분석기. 'tax-engine'과 'strategy-advisor' 에이전트가 세액을 계산하고 절세 전략을 수립할 때 이 스킬의 세율표, 계산 공식, 구간 분석 방법을 반드시 활용해야 한다. '세율 구간 분석', '세액 시뮬레이션', '한계세율 계산' 등에 사용한다. 단, 공제 최적화나 소득 분류는 이 스킬의 범위가 아니다.
Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The licence is Apache-2.0.
Example prompts
- “tax-engine”
- “strategy-advisor”
- “/tax-bracket-simulator”
What it can do on your machine
Read from SKILL.md and the folder at commit 8e8d35c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Tax Bracket Simulator loads about 659 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 138 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

소득세 세율 구간별 세액 계산, 한계세율 분석, 절세 포인트 식별.
종합소득세 세율표
2024년 기준 세율
| 과세표준 구간 | 세율 | 누진공제 | 구간 세액 |
|---|---|---|---|
| ~1,400만원 | 6% | 0 | 최대 84만원 |
| 1,400~5,000만원 | 15% | 126만원 | 최대 540만원 |
| 5,000~8,800만원 | 24% | 576만원 | 최대 912만원 |
| 8,800~1.5억원 | 35% | 1,544만원 | 최대 2,170만원 |
| 1.5~3억원 | 38% | 1,994만원 | 최대 5,700만원 |
| 3~5억원 | 40% | 2,594만원 | 최대 8,000만원 |
| 5~10억원 | 42% | 3,594만원 | 최대 21,000만원 |
| 10억원 초과 | 45% | 6,594만원 | - |
산출세액 속산 공식
산출세액 = 과세표준 × 세율 - 누진공제
예시: 과세표준 6,000만원
= 6,000만 × 24% - 576만 = 1,440만 - 576만 = 864만원
실효세율 = 산출세액 / 과세표준 × 100
= 864만 / 6,000만 × 100 = 14.4%세율 구간 경계 분석
구간 경계(Bracket Boundary) 절세 포인트
핵심 원리: 과세표준이 다음 구간에 진입하면 초과분에만 높은 세율 적용
절세 포인트 = 구간 경계 - 현재 과세표준
예시: 과세표준 5,100만원
- 5,000만원 초과 100만원에 24% 적용
- 100만원 소득공제 추가 시 → 24만원 → 15만원 (9만원 절약)
- 절세 효과: 소득공제 100만원당 9만원 추가 절세주요 구간 경계 전략
| 경계 | 세율 점프 | 전략 |
|---|---|---|
| 1,400만원 | 6%→15% | 소규모 소득자 공제 확인 |
| 5,000만원 | 15%→24% | 연금저축·IRP 납입 극대화 |
| 8,800만원 | 24%→35% | 고액 공제 항목 집중 활용 |
| 1.5억원 | 35%→38% | 소득 분산, 법인 전환 검토 |
| 3억원 | 38%→40% | 법인 설립, 퇴직금 활용 |
소득 유형별 세금 계산
근로소득
총급여
- 근로소득공제 = 근로소득금액
- 소득공제 = 과세표준
× 세율 - 누진공제 = 산출세액
- 세액공제 = 결정세액
- 기납부세액(원천징수) = 납부/환급세액
근로소득공제:
~500만: 70%
500~1,500만: 350만 + 초과×40%
1,500~4,500만: 750만 + 초과×15%
4,500~1억: 1,200만 + 초과×5%
1억 초과: 1,475만 + 초과×2%사업소득
총수입금액
- 필요경비 = 사업소득금액
경비 인정 방식:
1. 장부 기장: 실제 경비 인정 (기준경비율 적용)
2. 추계 신고: 단순경비율 / 기준경비율
단순경비율 적용 기준 (업종별):
- 제조업: 직전 수입 1.5억 미만
- 서비스업: 직전 수입 7,500만 미만
- 부동산임대: 직전 수입 7,500만 미만양도소득세
양도가액 - 취득가액 - 필요경비 = 양도차익
- 장기보유특별공제 = 양도소득금액
- 양도소득기본공제(250만원) = 과세표준
× 세율 = 양도소득세
부동산 세율:
1년 미만 보유: 70%
1~2년 보유: 60%
2년 이상 보유: 기본세율 (6-45%)
다주택자 중과: 기본세율 + 20~30%p
장기보유특별공제:
3년+: 연 2% (최대 30%)
