Tax moves people used

A viral tax thread turned a grab bag of legal tax breaks into a checklist: retirement plans, business structure, charitable giving, and medical accounts. (irs.gov) Several of the ideas in that list are real parts of the tax code, but they apply to different people and come with different limits, deadlines, and audit risks. The Internal Revenue Service says a one-participant 401(k) is for a business owner with no employees other than a spouse, not a universal write-off for anyone with side income. (irs.gov) For 2025, the Internal Revenue Service says the employee deferral limit for a 401(k) is $23,500, with a standard catch-up of $7,500 for people 50 and older and a larger $11,250 catch-up for some people ages 60 to 63. A solo plan can also allow employer contributions, subject to overall plan limits and compensation rules. (irs.gov) The Qualified Business Income deduction is another item that gets oversimplified online. The Internal Revenue Service says eligible taxpayers can deduct up to 20% of qualified business income, but wages earned as an employee do not count, and higher-income filers can run into extra limits that require the longer Form 8995-A calculation. (irs.gov, irs.gov) “Entity restructuring” usually means changing how a business is taxed, often by electing S corporation status on Form 2553. The Internal Revenue Service says S corporations pass income through to owners and avoid corporate-level federal income tax, but it also says shareholder-officers must take reasonable compensation as wages, and the agency can reclassify distributions if pay is set too low. (irs.gov, irs.gov) Roth conversions work differently from Roth contributions. The Internal Revenue Service says a conversion moves money from a traditional individual retirement account to a Roth individual retirement account, the converted amount is generally taxable in the year of the move, and conversions made after January 1, 2018 cannot be undone through recharacterization. (irs.gov, irs.gov) Donor-advised funds can also reduce taxes, but only if the donor itemizes and follows charitable deduction rules. The Internal Revenue Service says contributions to donor-advised funds are treated as gifts to a sponsoring public charity, while warning that some arrangements have been marketed to generate “questionable charitable deductions” and personal benefits that are not allowed. (irs.gov, irs.gov) Health savings accounts are the simplest item on many of these lists, but they still have eligibility rules. For 2025, the Internal Revenue Service says the contribution limit is $4,300 for self-only high-deductible health coverage and $8,550 for family coverage, plus a $1,000 catch-up for people 55 and older. (irs.gov, irs.gov) The common thread is timing. Solo 401(k) contributions, S corporation elections, Roth conversions, charitable gifts, and health savings account deposits all have tax-year rules, and missing the right filing date or paperwork can erase the benefit that made the strategy look so attractive online. (irs.gov, irs.gov, irs.gov) That is why two people can both copy the same viral checklist and get very different results on April 15. The tax code allows these moves, but the savings depend on income, business type, filing status, and whether the taxpayer actually qualifies for each one. (irs.gov, irs.gov)
