Coverage of the One Big Beautiful Bill Act tends to list the new deductions together, as though they were one package. They are not. Some of these provisions are permanent law and some expire on a fixed date, and the difference matters more than the headline amounts if you are planning more than a year ahead.
Working from a 26-row schedule of the statutory parameters (21 statutory values, 5 clearly-labelled illustrative estimates), the split is clean.
Permanent. The larger standard deduction is permanent, at $15,750 for single filers and $31,500 for married filing jointly in 2025. The child tax credit is permanent at $2,200 per qualifying child, of which $1,700 is refundable. The Section 199A qualified business income deduction stays at 20 percent, and from 2026 carries a $400 minimum for material participants.
Expires after 2028. The overtime, tips and senior deductions are all temporary. The overtime deduction is capped at $12,500 for single filers and $25,000 for joint filers, and phases out above $150,000 and $300,000 respectively. Tips are capped at $25,000 and $50,000. The senior deduction is $6,000 and $12,000.
The SALT cliff is the one to diary. The state and local tax cap rose to $40,000, with a phaseout starting at $500,000 of income at a rate of 6 percent. That elevated cap runs through 2029. In 2030 it reverts to $10,000. That is not a gradual taper; it is a step change of $30,000 in deductible headroom from one tax year to the next, and for anyone in a high-property-tax state it is the single largest scheduled change in this list.
The practical point is that three of these provisions are worth planning around only until 2028, one until 2029, and the rest are simply the new baseline. Treating them as one block leads to the wrong conclusion in both directions: over-weighting deductions that are about to lapse, and under-weighting the permanent ones.
None of the above is advice, and the dollar-savings figures in the underlying schedule are marked as estimates precisely because what a deduction is worth depends on your marginal rate. Statutory parameters are from IRS guidance on the Act (Public Law 119-21).
