Save tax pillar
U.S. tax guides — brackets, accounts, and the moves that move the needle
Most American households can cut their lifetime tax bill more by maxing tax-advantaged accounts (401(k), IRA, HSA) and harvesting losses than by chasing deductions. Pick the right account, file once with the right software, and revisit your bracket each November.
FinBrief's Save tax pillar covers the 2026 federal tax brackets (IR-2025-103), Roth and HSA strategies, filing software comparisons, and retirement-tax rules including SECURE 2.0 changes and RMDs. All limits are pulled from the primary IRS revenue procedures — see the citations on each article for source documents.

Roth IRA and conversion strategies
The 2026 Roth IRA limit is $7,500 ($1,100 catch-up at 50+) per IR-2025-111. High earners can use backdoor Roth (after-tax to Roth) and mega backdoor Roth (after-tax 401(k) to Roth) to contribute well beyond the standard limit.

HSA, FSA, and 529 plans
The HSA is the only triple-tax-advantaged account: deductible going in, tax-free growth, tax-free withdrawal for medical. 2026 limits: $4,400 self / $8,750 family / +$1,000 catch-up at 55+ (Rev. Proc. 2025-19). FSAs forfeit unused balances; HSAs roll over forever.

Retirement tax rules and SECURE 2.0
SECURE 2.0 raised the RMD age to 73 (75 starting 2033) and created a super catch-up for ages 60–63 of $11,250 in 2026. Up to 85% of Social Security can be taxable depending on combined income.
Tax-loss harvesting
Sell losing positions to offset realized gains, then use up to $3,000/year against ordinary income (carryover thereafter). Watch the 30-day wash-sale rule — buying back the same or substantially identical security disallows the loss.
Frequently asked questions
- What are the 2026 federal tax brackets?
- Seven brackets ranging from 10% to 37%, with bracket thresholds adjusted annually for inflation under Rev. Proc. 2025-32 (IR-2025-103). Standard deduction is $16,100 single / $32,200 MFJ / $24,150 HoH.
- What's the 2026 401(k) contribution limit?
- $24,500 elective deferral, $8,000 catch-up at 50+, and a SECURE 2.0 super catch-up of $11,250 for ages 60–63 (IR-2025-111). The IRA limit is separately $7,500 / $1,100 catch-up.
- Is the HSA really triple-tax-advantaged?
- Yes — contributions are pre-tax (or above-the-line deductible), growth is tax-free, and withdrawals for qualified medical expenses are tax-free at any age. After 65 you can withdraw for any reason at ordinary-income rates, like a Traditional IRA.
- Do I need to file taxes if I made under the standard deduction?
- Often no, but you should file anyway if any income tax was withheld (to get the refund), if you qualify for refundable credits like EITC, or if you had self-employment income above $400.
- What's the difference between FSA and HSA?
- An FSA is use-it-or-lose-it (or roll over $660 max in 2026) and tied to your employer. An HSA rolls over forever, can be invested, and follows you between jobs — but requires a high-deductible health plan to contribute.
- When should I hire a CPA instead of using software?
- When you have RSUs vesting, K-1s from a partnership or LLC, rental property income, multi-state filings, a Roth conversion, or you sold a business. Software handles W-2 + 1099 + standard deduction filings well.
