Tax Loss Harvesting Madison: 2026 Guide to Saving on Your Taxes
Updated for 2026: If you’re a Madison, Wisconsin investor, business owner, or anyone with taxable investment accounts, this guide covers everything you need to know about tax loss harvesting in 2026—using only verified current rules, IRS updates, and new legislative changes.
What is Tax Loss Harvesting?
Tax loss harvesting is when you intentionally sell investments that have dropped in value, realizing a capital loss that you can use to offset capital gains—and sometimes even ordinary income. Used strategically, this means less taxation in good years and a smoother ride in volatile ones.
2026 Quick Facts: Capital Loss Deduction & Wash Sale Rule
- Capital Loss Deduction Limit (2026): $3,000 per year net capital loss against ordinary income (Unchanged for 2026)
- Wash Sale Rule (2026): 30-day period before and after the sale; repurchasing substantially identical securities within this period disallows the deduction (No 2026 change)
- New in 2026: Wash sale rule still applies, but recent federal legislation created fresh opportunities to combine tax loss harvesting with bonus depreciation
Table 1: 2026 Tax Loss Harvesting Reference
| Rule | 2025 | 2026 |
|---|---|---|
| Capital Loss Deduction Limit | $3,000 | $3,000 |
| Wash Sale Window | 30 days | 30 days |
| Short/Long-Term Gain Rates | Varies | Varies (No change) |

Why Madison?
Although federal tax law applies everywhere, Wisconsin’s state tax rules, cost of living, and investor demographics make Madison an excellent city to optimize your strategy. Madison residents must pay both federal and Wisconsin capital gains tax (state rate up to 7.65% on long-term gains; 30% exclusion applies on LTCG for most assets). High-income earners, self-employed, and retirees with brokerage accounts are especially well-positioned to benefit.
2026 Legislative Changes: What’s New and How Does It Affect You?
- 100% Bonus Depreciation Restored: New or used property purchased after Jan 19, 2025 gets full expensing. This can combine with capital loss harvesting to reduce overall taxable income.
- Section 199A QBI Deduction Permanent: Up to 20% deduction on qualified business income, plus new $400 minimum applies in 2026 for eligible filers.
- 1099-K Threshold Raised: No more $600 surprise—now only applies if you receive $20,000+ and over 200 transactions.

Step-By-Step: How to Tax Loss Harvest in Madison (2026)
- Review Your Portfolio. Identify securities with losses (stocks, ETFs, crypto, etc.)
- Confirm Cost Basis. Ensure your records are accurate—especially for older holdings
- Sell Loss Positions Before Year-End. Capital losses must be realized in the year you want to claim the deduction.
- Avoid the Wash Sale Trap. Wait at least 31 days before repurchasing the same or a ‘substantially identical’ security.
Tip: You can buy a similar, but not identical, investment to keep market exposure (e.g., sell S&P 500 index fund, buy total market fund). - Match With Gains. Offset short-term losses against short-term gains first, then long-term; $3,000 annual cap applies if you have more losses than gains.
- Report Properly. Use Schedule D, and for new deduction opportunities, use Schedule 1-A for 2026 as required by IRS Notice 2026-16.
- Check State Tax Forms. Wisconsin follows most of the federal treatment, but confirm if specific adjustments are needed (capital loss carryforward, etc).
Who Should Use Tax Loss Harvesting in 2026?
- Investors with taxable (not retirement) accounts in Madison
- Business owners with gains from recent sales or investments
- High-income filers seeking to offset large capital gains
- Retirees with significant brokerage holdings
