What is thai-financial-projection?

A three-year financial projection guide for Thai small and medium-sized businesses. It covers profit and loss, cash flow, corporate tax tiers, value-added tax, employee social-security contributions, and tax filing timing.

Use it to model revenue, costs, taxes, VAT, social-security payments, and cash flow for a Thai business, including checks for when SME tax rules no longer apply.

It avoids treating every company as if it paid one flat tax rate and helps account for Thai tax and payroll timing in cash planning.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00067	$0.01718
Opus 5	$0.00034	$0.00859
Sonnet 5	$0.00013	$0.00344
Haiku 4.5	$0.00007	$0.00172

Security

Grade A, and why

thai-financial-projection scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (tax.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Thai Financial Projection — SME P&L with correct tax tier

ปัญหาที่เจอบ่อยที่สุดในงานที่ปรึกษา: Claude (หรือ template ที่เถ้าแก่หามาจาก internet) ใช้ corporate tax 20% flat — ทั้งที่ SME ไทย (ทุนชำระ ≤5M, รายได้ ≤30M ต่อปี) เสีย 0% ที่กำไรสุทธิ <300k, 15% ที่ 300k-3M, แล้วค่อย 20%. ความแตกต่างปีละ 200-500k.

tax.py ใน skill นี้ทำ tier-correct calculation + รวม VAT cycle + SSO + WHT timing.

เมื่อ Claude เห็นคำขอแบบนี้

ทำ 3-yr P&L ร้านขายของออนไลน์ ทุนชำระ 1M รายได้ปีแรก 2.4M
เครื่องสำอางขายปีหนึ่ง 18M EBITDA 4.2M net profit หลังภาษีเท่าไหร่

ขั้นตอน (Claude ทำตามนี้)

เก็บ input ขั้นพื้นฐาน
- ประเภทกิจการ (บริษัทจำกัด / หจก. / sole prop)
- ทุนชำระแล้ว
- รายได้รวมต่อปี (ถ้าไม่ใช่ SME tier ใช้ flat 20%)
- ค่าใช้จ่ายรวม (COGS + opex + interest)
- จำนวนพนักงาน (สำหรับ SSO 5% + 5%)
- ขึ้น VAT แล้วหรือยัง (trigger ที่ 1.8M รายได้/ปี)

เรียก tax.py

from tax import sme_corporate_tax, sso_employer_contribution, vat_breakeven

คืน P&L 3 ปีในตาราง markdown พร้อม row "Income tax" ที่คำนวนถูกตาม tier
ข้อสังเกต
- ปีไหน gross revenue >30M ออกจาก SME tier → flag
- ปีไหน paid-up capital >5M ออกจาก SME tier → flag
- ถ้ายังไม่ได้ขึ้น VAT แต่ revenue จะแตะ 1.8M ปีนั้น → flag เดือนที่ trigger
- SSO cap ที่ฐานเงินเดือน 15,000฿/เดือน — ลูกจ้างที่ได้สูงกว่าจ่ายสูงสุด 750฿ ทั้งสองฝั่ง

ตัวอย่าง

Input

บริษัทจำกัด ทุนชำระ 2M รายได้ปีที่ 1 = 8M, ปีที่ 2 = 18M, ปีที่ 3 = 28M
ค่าใช้จ่ายรวม (ก่อนภาษี) = 60% ของรายได้
มีพนักงาน 6 คน เงินเดือนเฉลี่ย 22,000
ขึ้น VAT แล้ว

Output (sample)

| รายการ                | ปี 1 (8M)  | ปี 2 (18M) | ปี 3 (28M) |
|-----------------------|-----------:|-----------:|-----------:|
| รายได้                |  8,000,000 | 18,000,000 | 28,000,000 |
| ค่าใช้จ่าย             |  4,800,000 | 10,800,000 | 16,800,000 |
| SSO นายจ้าง 5%        |     54,000 |     54,000 |     54,000 |
| EBITDA                |  3,146,000 |  7,146,000 | 11,146,000 |
| Net before tax        |  3,146,000 |  7,146,000 | 11,146,000 |
| Income tax (SME tier) |    374,200 |  1,374,200 | ----       |
| Income tax (flat 20%) |    ----    |     ----   |  2,229,200 |
| Net after tax         |  2,771,800 |  5,771,800 |  8,916,800 |

ข้อสังเกต:
- ปีที่ 3 รายได้ 28M ใกล้แตะเพดาน SME 30M — ถ้าปีที่ 4 เกินจะออกจาก SME tier ต้องวางแผน
- SSO นายจ้าง ฐาน 15,000 × 5% × 12 เดือน × 6 คน = 54,000 (พนักงานเงินเดือนเฉลี่ย 22k > 15k cap → ใช้ cap)
- ภงด.51 ครึ่งปีต้องประมาณการ — ถ้าประมาณต่ำกว่า 25% ของจริง โดน penalty 20%
