Tax Carryovers You're Missing: Stop Overpaying on Your Return

Why Prior Year Returns Matter

When preparing your current year tax return, you should always review the prior year return first. Carryover items from previous years can reduce your current tax bill, but they are easy to miss if you are not looking for them. Always pull up last year's PDF and check for carryforward amounts before filing this year.

Common Carryover Items

Capital loss carryover (Schedule D): If your investment losses exceeded $3,000 (the annual deduction limit), the excess carries forward to future years to offset future capital gains or ordinary income. Passive activity losses (Form 8582/Schedule E): Rental losses or K-1 losses from passive activities that were limited in prior years can carry forward when you have passive income or dispose of the activity.

Additional carryovers include Net Operating Losses (NOL), unused charitable contribution deductions (limited to 60% of AGI in the contribution year), AMT credits from prior years, and foreign tax credit carryforwards. Each of these can put money back in your pocket if you know to look for them.

Coverage Check: Filing All Required Returns

Beyond carryovers, confirm that all required tax filings are covered. Single-member LLC owners, freelancers, rental property owners, and investors with K-1 income may have multiple filing obligations beyond the basic Form 1040. Missing an information return like Form 5472 or FBAR can result in penalties that dwarf any tax savings.

A thorough filing checklist should cover: income tax returns, self-employment tax, estimated tax payments, information returns for foreign accounts and entities, and state tax returns.
