Purpose

Implement A-share tax loss offset — systematic tax-loss harvesting for Chinese investment portfolios.

Data Sources

Primary: iFind MCP (Tier-1 paid) / AkShare MCP (Tier-2 free alternative)

get_quote(ticker)                     → Current prices for holdings
get_historical_data(ticker)           → Cost basis / purchase history

Secondary Sources

• Broker records — cost basis, trade history
• Tax filings — prior year losses
• Exchange — tax treatment rules

Workflow

Step 1: Identify Tax-Loss Positions

Loss identification:

Position	Ticker	Cost Basis	Current Value	Unrealized Loss	Loss %
		¥XX	¥XX	¥XX	X%

Loss screening criteria:

• Unrealized loss > 10% of cost basis
• Loss amount significant relative to portfolio
• Holding period appropriate for tax treatment

Step 2: Understand A-share Tax Rules

China tax treatment for securities:

Item	Tax Rate	Notes
Securities trading price spread	Temporarily exempt (temporarily exempt)	Capital gains on stocks
Dividends	20% (halved to 10% if holding >1 year, exempt if >1 year)	Dividend tax
Fund distributions	Temporarily exempt (some funds)	Fund distributions
Trading stamp duty	0.05% (seller only)	Stamp duty
Securities trading commission	0.02-0.03%	Commission

Current status of capital gains tax:

• Individuals: Capital gains on stocks are currently temporarily exempt (temporarily exempt)
• However, losses can be used to offset gains within the same year
• Loss carryforward rules may apply

Step 3: Calculate Tax Benefit

Tax benefit calculation:

Scenario	Gain	Loss	Taxable Gain	Tax Saved
Without TLH	¥XX	—	¥XX	—
With TLH	¥XX	¥XX	¥XX	¥XX
Benefit				¥XX

Note: In the current A-share environment where capital gains are largely exempt, tax-loss harvesting benefits may be limited. However:

• Harvesting losses can be valuable if tax rules change
• Offsetting gains within the same year
• Potential future tax benefit if capital gains tax is introduced

Step 4: Identify Replacement Securities

Replacement criteria:

Criterion	Requirement
Same sector	Similar industry exposure
Similar characteristics	Market cap, growth, quality
Not substantially identical	Avoid wash sale rules
Tax-efficient	Consider dividend treatment

Wash sale considerations (China):

• No explicit wash sale rule currently
• However, substantially identical securities may be disallowed
• Best practice: 30-day waiting period

Step 5: Execution Strategy

Execution options:

Strategy	Description	Pros	Cons
Full exit	Sell and replace	Clean loss realization	Market risk
Partial exit	Reduce position	Partial benefit	Partial benefit only
Swap	Sell loss, buy similar	Maintain exposure	Timing risk
Delay	Wait for recovery	No transaction costs	Missed opportunity

Step 6: Implementation Plan

Step-by-step plan:

Step	Action	Timing
1	Identify loss positions	Pre-year-end
2	Evaluate replacement options	Pre-year-end
3	Check wash sale rules	Pre-year-end
4	Execute sales	Before year-end
5	Execute purchases	After sale (or simultaneously)
6	Document transactions	Immediately
7	File tax forms	Tax filing deadline

Step 7: Document for Tax Filing

Required documentation:

Document	Content
Trade confirmations	Sale and purchase tickets
Cost basis records	Purchase prices, dates
Loss calculations	Realized loss amounts
Replacement securities	Identified alternatives
Market rationale	Investment thesis

Step 8: Year-End Checklist

Year-end TLH checklist:

Date	Action
Nov	Review portfolio for loss positions
Dec 1-15	Identify replacement securities
Dec 15-20	Execute loss sales
Dec 20-31	Execute replacements
Dec 31	Final portfolio review
Jan	File tax documentation

China-Specific TLH Considerations

Current Tax Environment

Factor	Status	Implication
Capital gains tax	Temporarily exempt (temporarily exempt)	Limited current benefit
Stamp duty	0.05%	Cost on sale
Dividend tax	20% (10% for >1yr)	Consider in replacement
Trading commission	0.02-0.03%	Trading cost

When TLH Makes Sense in China

Scenario	Benefit
Offset short-term gains	Use losses against gains
Reset cost basis	Lower future gains if taxed
Prepare for tax changes	If capital gains taxed in future
Portfolio rebalancing	Combine with rebalancing

A-share Market Timing

Consideration	Guidance
Year-end effect	Year-end selling pressure
Price limit restrictions	May prevent execution
Liquidity	Ensure liquidity for exit
Policy window	Tax policy change risk

TLH for Different Client Types

Individual Investors

Consideration	Guidance
Holding period	>1 year for dividend tax benefit
High-frequency trading	May trigger scrutiny
Amount threshold	Focus on significant positions

Institutional Investors

Consideration	Guidance
Transaction costs	Factor in commission impact
Market impact	Large position impact
Accounting treatment	NAV impact timing
Compliance review	Documentation requirements

Quality Checks

Before executing:

• Loss positions identified
• Tax benefit calculated
• Replacement securities identified
• Wash sale rules considered
• Execution plan clear
• Documentation prepared
• Timing appropriate

Data Source Mode Switch: Set env var IFIND_DATA_SOURCE_MODE to control data source preference.

• ifind-only (strict): Use iFind only, error if unavailable
• ifind-fallback (default): iFind preferred, fallback to AkShare
• akshare-only, wind-only (Wind only), wind-fallback (Wind first, fallback to iFind → AkShare): Skip iFind, use AkShare only
