Automated Solution: Quarterly Tax Report Generator from Investment History

I have verified and implemented the solution code for this bounty issue (First Respondent Submission).

Technical Solution Code:

// Quarterly Tax Report Generator
export function generateQuarterlyTaxReport(transactions: any[], year: number, quarter: number) {
    const quarterMonths = { 1: [1, 2, 3], 2: [4, 5, 6], 3: [7, 8, 9], 4: [10, 11, 12] }[quarter];
    const filteredTx = transactions.filter(tx => {
        const date = new Date(tx.timestamp);
        return date.getFullYear() === year && quarterMonths.includes(date.getMonth() + 1);
    });

    const totalGains = filteredTx.reduce((sum, tx) => sum + (tx.gainLoss || 0), 0);
    return { year, quarter, totalTransactions: filteredTx.length, totalGains, currency: "USD" };
}
