Top 5 Things Investors Need to Consider Before Filing Their Taxes This Year
Tax season isn’t just about plugging numbers into software and hitting “submit.” For investors, filing taxes is a strategic opportunity to reduce future tax bills, improve portfolio efficiency, and avoid costly mistakes. Whether you actively trade, hold long-term investments, or generate income from dividends and interest, understanding how taxes impact your investments is critical.
Before you file your taxes this year, here are five key investment-related tax considerations every investor should review.
1. Capital Gains and Losses Matter More Than You Think
One of the biggest tax considerations for investors is capital gains tax. Short-term capital gains (investments held less than one year) are taxed at ordinary income tax rates, while long-term capital gains receive preferential tax treatment.
Before filing, review:
Which assets were sold
How long each investment was held
Whether gains were short-term or long-term
Equally important is capital loss harvesting. If you realized losses during the year, those losses can offset capital gains dollar-for-dollar. If losses exceed gains, up to $3,000 can offset ordinary income, with the remainder carried forward.
Failing to properly account for capital gains and losses can result in paying far more in taxes than necessary.
2. Dividend and Interest Income Can Create Surprise Tax Bills
Many investors underestimate the tax impact of dividend income and interest income, especially when investing in taxable brokerage accounts.
Key items to review:
Qualified vs. non-qualified dividends
Bond interest and money market income
REIT distributions, which are often taxed as ordinary income
Even if you reinvest dividends automatically, the IRS still considers that income taxable. Reviewing your 1099-DIV and 1099-INT forms carefully helps avoid underreporting income and potential penalties.
Understanding where income-producing assets are held (taxable vs. tax-advantaged accounts) can dramatically improve long-term tax efficiency.
3. Retirement Contributions and Deadlines Can Still Reduce Taxes
One of the most overlooked tax planning opportunities happens before the tax filing deadline. Depending on your situation, you may still be able to make contributions to:
Traditional IRAs
SEP IRAs
Solo 401(k)s
These contributions may reduce your taxable income for the prior year. Investors should also verify that reported contributions to 401(k)s and IRAs are accurate and within IRS limits.
Additionally, Roth IRA contributions don’t provide an immediate tax deduction, but verifying eligibility and contribution accuracy is critical to avoiding future tax issues.
Schedule a Tax-Smart Portfolio Review
Before you file, it may be worth taking a step back. A tax-smart portfolio review can help identify unrealized gains and losses, tax inefficiencies, and opportunities to improve after-tax returns.
4. Investment Account Location Impacts Your Tax Bill
Not all investment accounts are taxed equally. One major tax consideration investors often miss is asset location, or which investments are held in which accounts.
Examples include:
Holding tax-efficient ETFs in taxable accounts
Placing bonds and high-income investments in tax-deferred accounts
Using Roth accounts for growth-oriented investments
While asset location doesn’t change what you owe this year, it plays a massive role in long-term tax efficiency and should be reviewed annually during tax season.
5. Required Minimum Distributions and Special Tax Rules
If you’re age 73 or older, Required Minimum Distributions (RMDs) must be taken from certain retirement accounts. Missing an RMD can result in steep IRS penalties.
Other tax considerations to review include:
Net Investment Income Tax (NIIT)
Alternative Minimum Tax (AMT)
State and local tax treatment of investment income
High-income investors are especially vulnerable to additional surtaxes if these items are overlooked.
Why Reviewing Investment Taxes Before Filing Matters
Taxes and investing are deeply connected. Filing without reviewing investment-related tax details can lock in mistakes that compound over time. A proactive review helps investors reduce taxes, improve after-tax returns, and align their financial strategy with long-term goals.
Working with a financial advisor and tax professional together can ensure your investment strategy and tax strategy are fully aligned—not working against each other.
If you want to make smarter decisions before filing your taxes this year, now is the time to review your portfolio through a tax-aware lens.
