Hodu Atlas AI Tax Calculator — Concept Preview (Hodu Atlas AI 세금 계산기 개념 미리보기)

Every Korean digital nomad knows the pain: earned in USD, crypto on Binance, freelance invoices in EUR. Tax season means days of spreadsheet work across multiple currencies.

What if AI could do it in minutes? Here's the Hodu Atlas AI Tax Calculator concept — plus a prompt you can use today.

🇰🇷 오늘 당장 쓸 수 있는 프롬프트

Copy this into ChatGPT with your numbers:

I'm a Korean digital nomad with:
- US dividends: $3,200 (15% withholding)
- Freelance USD invoices: $18,000
- Korean salary: ₩36,000,000
- Crypto gains: $2,500

Calculate: total income in KRW (avg rate 1,350), estimated tax, 해외주식 양도소득세 (250만 원 threshold), and foreign tax credit for US withholding.

ChatGPT returns a structured estimate in 30 seconds.

What the Concept Tool Adds

We're prototyping a purpose-built AI tax calculator that goes further:

• Auto currency conversion at historical rates per transaction date
• Income classification — W-2 vs freelance vs capital gains vs crypto
• Tax treaty engine — applies US-Korea, Korea-Singapore rules automatically
• Hometax-ready output — generates a 홈택스-compatible Korean summary

No more digging through IRS Publication 901 or treaty PDFs. The AI reads them so you don't have to.

🚀 Workflow for Today

1. Export brokerage CSV
2. Paste into Google Sheets with =GOOGLEFINANCE("USDKRW", date) for each row
3. Ask ChatGPT to calculate net gains in KRW
4. File in 홈택스 (cross-check 3 rows)
