Calculate Connecticut income tax recapture for high earners. See the effective 8%+ marginal rate spike in the phase-out zone above $200K (single) and $400K (MFJ). Tax planning to stay below thresholds.
How CT Tax Recapture Works
Connecticut has seven income tax brackets ranging from 3% to 6.99%. However, a unique recapture mechanism eliminates the benefit of lower brackets for high-income taxpayers, creating an effective marginal rate spike that can exceed 8%.
CT Tax Brackets 2026
Single: 3% (0โ$10K) | 5% ($10Kโ$50K) | 5.5% ($50Kโ$100K) | 6% ($100Kโ$200K) | 6.5% ($200Kโ$250K) | 6.9% ($250Kโ$500K) | 6.99% ($500K+)
MFJ: 3% (0โ$20K) | 5% ($20Kโ$100K) | 5.5% ($100Kโ$200K) | 6% ($200Kโ$400K) | 6.5% ($400Kโ$600K) | 6.9% ($600Kโ$1M) | 6.99% ($1M+)
Recapture Formula
Single: +$90 per $5,000 above $200,000 (up to max ~$2,250)
MFJ: +$180 per $10,000 above $400,000 (up to max ~$4,500)
Effective Marginal Rate in Phase-Out Zone = 6.5% + recapture โ 8%+
Frequently Asked Questions
What is Connecticut tax recapture?
Connecticut tax recapture phases out the benefit of lower tax brackets for high earners. When your CT taxable income exceeds $200,000 (single) or $400,000 (MFJ), you lose the advantage of having income taxed at the lower 3% and 5% bracket rates. This creates an effective marginal rate spike in the phase-out zone, sometimes exceeding 8%.
How is CT tax recapture calculated?
For single filers, every $5,000 of income above $200,000 adds $90 of recapture. For MFJ, every $10,000 above $400,000 adds $180. The recapture continues until all lower-bracket benefits are fully recovered (maximum recapture). This means your effective rate in the phase-out zone can reach 8%+.
What is the maximum CT recapture amount?
The maximum recapture equals the total "savings" from lower brackets. For single filers this is approximately $2,250, and for MFJ approximately $4,500. Once income is high enough that maximum recapture is reached, the effective rate returns to the 6.99% top rate on additional income.
How should I plan around CT tax recapture?
Key strategies include: (1) Stay below the $200K/$400K recapture threshold if possible; (2) Accelerate or defer income to avoid straddling the threshold; (3) Maximize pre-tax retirement contributions (401k, IRA) to reduce CT taxable income; (4) Harvest investment losses in high-income years to pull income below the recapture zone.
Does CT recapture affect capital gains?
Yes. Connecticut taxes capital gains as ordinary income at the same rates. Capital gains pushing income into or through the recapture zone will face the elevated effective marginal rate. This is an important consideration for asset sale timing in Connecticut.
