What is the self-employment tax rate for 2026?

The self-employment tax rate is 15.3% for 2026: 12.4% for Social Security and 2.9% for Medicare, applied to 92.35% of net self-employment earnings rather than the full amount. The 12.4% Social Security portion only applies up to the 2026 Social Security wage base of $184,500; the 2.9% Medicare portion applies to all net self-employment earnings with no cap.

When are quarterly estimated tax payments due in 2026?

For the 2026 tax year, estimated payments are generally due April 15, 2026; June 15, 2026; September 15, 2026; and January 15, 2027. Any date that falls on a weekend or federal holiday shifts to the next business day. Payments are made using IRS Form 1040-ES or through the IRS's online payment portal.

How do I avoid an underpayment penalty as a freelancer?

The IRS 'safe harbor' rule protects you from an underpayment penalty if your withholding and estimated payments together equal at least 90% of your current-year tax liability, or 100% of your prior-year tax liability (110% if your prior-year adjusted gross income was over $150,000, or $75,000 if married filing separately). Meeting either threshold avoids the penalty even if you end up owing a balance when you file.

Do I owe self-employment tax if I also have a W-2 job?

Yes. Self-employment tax applies to net self-employment earnings of $400 or more regardless of whether you also hold a W-2 job. However, wages already subject to Social Security tax at your W-2 job count toward the annual Social Security wage base first, which can reduce or eliminate the 12.4% portion owed on your self-employment income for that year.

Can I deduct self-employment tax?

Yes. You can deduct half of your base self-employment tax — the Social Security and Medicare portions, not the Additional Medicare Tax — as an above-the-line adjustment to income on Schedule 1 of Form 1040. This deduction lowers your adjusted gross income and reduces your income tax, though it does not reduce the self-employment tax itself.

What triggers the Additional Medicare Tax?

An extra 0.9% Additional Medicare Tax applies to combined wages and self-employment earnings above $200,000 for single filers or $250,000 for married couples filing jointly, on top of the standard 2.9% Medicare portion. Unlike regular Medicare tax, this additional amount is not matched by an employer and is reported on Form 8959.

How much can I contribute to a 529 plan in 2026 without gift tax?

An individual can contribute up to $19,000 per beneficiary in 2026 without it counting against the annual gift tax exclusion; a married couple can jointly contribute up to $38,000 per beneficiary. Using "superfunding" (electing to spread a larger gift over 5 years on a gift tax return), an individual can front-load up to $95,000 and a married couple up to $190,000 per beneficiary in a single year without touching the lifetime gift and estate tax exemption.

Can I roll over unused 529 funds into a Roth IRA?

Yes, under a SECURE 2.0 Act provision. Up to $35,000 (lifetime, per beneficiary) can be rolled from a 529 plan into a Roth IRA for that beneficiary, subject to several conditions: the 529 account must have been open for at least 15 years, contributions and earnings from the last 5 years are not eligible for rollover, the annual rollover amount is capped at that year's regular Roth IRA contribution limit, and the beneficiary must have earned income at least equal to the amount rolled over that year. Unlike normal Roth contributions, this rollover has no income limit for the beneficiary.

What can 529 funds be used for besides college tuition?

Beyond college tuition, fees, room, board, books, and supplies, 529 funds can cover up to $20,000 per year in K-12 tuition (following a 2025 legislative expansion), certain registered apprenticeship program expenses, and up to $10,000 lifetime per beneficiary toward qualified student loan repayment. Using funds for non-qualified expenses generally triggers income tax plus a 10% penalty on the earnings portion of the withdrawal.

Do most people know what a 529 plan actually does?

Survey data suggests significant confusion. One 2026 survey found only about a third of adults could correctly identify a 529 plan's primary purpose, and a separate survey of parents found roughly half were aware that unused 529 funds could be rolled into a Roth IRA under the SECURE 2.0 provision.

What happens if I don't use all the money in a 529 plan?

Unused funds are not lost. The account owner can change the beneficiary to another qualifying family member without penalty, use up to $35,000 lifetime for a Roth IRA rollover if eligibility conditions are met, or leave the funds invested for a future qualified use, such as graduate school. Only a non-qualified withdrawal (spent on something outside the qualified expense categories) triggers income tax and a 10% penalty on the earnings portion.

What is tax-loss harvesting?

Tax-loss harvesting is selling an investment that has lost value to realize a capital loss, which can offset capital gains realized elsewhere in your portfolio and, within limits, offset a portion of ordinary income. The proceeds are typically reinvested in a similar but not identical holding to keep the portfolio's overall market exposure roughly the same.

What is the wash-sale rule?

Under Internal Revenue Code Section 1091, if you sell a security at a loss and buy the same or a substantially identical security within 30 days before or after the sale (a 61-day window total), the loss is disallowed for tax purposes and added to the cost basis of the replacement shares instead of being deductible immediately.

How much can I deduct from ordinary income with tax-loss harvesting?

After capital losses offset all capital gains for the year, up to $3,000 of any remaining net capital loss ($1,500 if married filing separately) can offset ordinary income in that tax year. Any loss beyond that amount carries forward indefinitely to future tax years, subject to the same rules.

Does the wash-sale rule apply to cryptocurrency?

Not currently. The wash-sale rule under Section 1091 applies to securities, and the IRS treats cryptocurrency as property rather than a security, so crypto trades are not subject to the 30-day wash-sale restriction as of August 2026. This is actively changing on the legislative front: Rep. Jodey Arrington introduced H.R. 9172 in June 2026 to extend the wash-sale rule to digital assets, building on earlier Senate and House proposals, and tax specialists broadly expect an eventual extension even though passage before the 2026 midterms is considered unlikely. Confirm the current-year status before relying on this strategy heavily.

When is the deadline for tax-loss harvesting?

For most taxpayers using the calendar year as their tax year, trades must settle by December 31 to count for that tax year. Because trade settlement can take a business day or more, most advisors recommend placing loss-harvesting trades well before the final trading days of the year rather than waiting until December 31 itself.

What is the HSA contribution limit for 2026?

For 2026, the IRS HSA contribution limit is $4,400 for self-only HDHP coverage and $8,750 for family HDHP coverage. Individuals age 55 or older can make an additional catch-up contribution of $1,000 on top of either limit. These figures are adjusted annually for inflation — confirm the current year's limits at IRS.gov (Publication 969) before contributing.

What is the HSA triple tax advantage?

The HSA triple tax advantage works in three stages: (1) Contributions are tax-deductible (or pre-tax if made via payroll), reducing your taxable income in the year you contribute. (2) Money inside the HSA grows tax-free — interest, dividends, and investment gains are not taxed while the funds stay in the account. (3) Withdrawals are tax-free when used for qualified medical expenses, with no expiry or deadline on when you must spend the money. No other mainstream U.S. savings account offers all three of these benefits simultaneously.

What qualifies as an HSA expense?

Qualified HSA expenses include most out-of-pocket medical, dental, and vision costs: deductibles, copays, prescription drugs, dental cleanings and treatment, eyeglasses and contact lenses, hearing aids, and many medical devices. They do not include most insurance premiums (with limited exceptions such as COBRA, long-term care insurance up to IRS limits, or premiums while receiving unemployment benefits), gym memberships, cosmetic procedures, or over-the-counter items not prescribed by a doctor. The IRS maintains the full list in Publication 502.

Can I use my HSA as a retirement account?

Yes — after age 65, you can withdraw HSA funds for any purpose, not just medical expenses. Non-medical withdrawals after 65 are taxed as ordinary income (similar to a traditional IRA), but the 20% penalty that applies before age 65 disappears. Meanwhile, any withdrawals for qualified medical expenses remain tax-free at any age. Because healthcare costs are typically one of the largest expenses in retirement, an HSA used as a 'stealth' retirement account lets you pay those costs with tax-free dollars while non-medical withdrawals still avoid the early-withdrawal penalty that would apply before 65.

Do I have to spend my HSA money each year?

No — unlike a Flexible Spending Account (FSA), an HSA has no 'use it or lose it' rule. Unused balances roll over indefinitely from year to year. You can also reimburse yourself for qualified medical expenses you paid out of pocket in a prior year, as long as the expense occurred after your HSA was established — keeping receipts is essential for this strategy.
