Two Medicare late enrollment penalties are described the same way in almost every summary: sign up late, pay more for life. They are built on different units. The Part D drug penalty counts single months and multiplies them by a premium figure that the Centers for Medicare & Medicaid Services resets every year. The Part B medical penalty counts only completed twelve-month periods and multiplies them by a much larger premium. For 2026 the two base figures are $38.99 and $202.90. What follows is what each formula does with the same gap, and why one of them costs a different amount every January while the gap behind it does not change. What Starts the Part D Count The condition is not lateness in general. The Medicare drug coverage cost page states: “You may owe a late enrollment penalty if at any time after your Initial Enrollment Period is over, there’s a period of 63 or more days in a row when you don’t have Medicare drug coverage or other creditable prescriptio...

For the 2026 tax year the IRS raised the annual limit on contributions to a traditional or Roth IRA to $7,500, and set the deduction phase-out range for a single filer covered by a workplace plan at $81,000 to $91,000. Both figures come from IRS Notice 2025-67, announced in the IRS news release on 2026 retirement plan limits. Between them sit two numbers no tax form prints. The first is the income figure actually compared against the range, which is not the adjusted gross income at the bottom of the return. The second is the reduced deduction, which IRS Publication 590-A does not produce as a straight proportion: it rounds the answer up, and it refuses to let the answer fall below $200 while any of the range remains. Coverage at Work Decides Whether the Income Test Runs at All The phase-out is conditional, and the condition is not income. IRS Publication 590-A, in the edition for use in preparing 2025 returns, splits the question across two tables, one headed “Effect of Modifie...

Treasury’s Daily Treasury Bill Rates table for September 3, 2026 lists the 26-week bill at 3.86 percent. A six-month certificate of deposit advertised at 4.00 percent APY looks higher by 14 basis points. The two figures are not measured on the same scale. One is a discount quote struck against par on a 360-day year; the other is an annual effective yield; and only one of them escapes state income tax. Converted onto a single scale, the same bill is 4.03 percent, and the state exemption moves the line a second time. What follows is the conversion, the statute behind the exemption, and the point at which a higher headline deposit rate stops winning. One Bill Carries Three Different Rates Two of the three are published side by side. The Treasury page that carries the daily series defines the first column this way: “The Bank Discount rate is the rate at which a bill is quoted in the secondary market and is based on the par value, amount of the discount and a 360-day year....

September 15, 2026 is a Tuesday, and it is the due date for the third of the four required installments of 2026 federal estimated tax. Two separate rules decide what happens on that date. One fixes how large the installment has to be. The other decides what accrues if it comes up short, and that second rule is written as a rate applied for a number of days rather than as a flat late charge. Both rules sit in section 6654 of the Internal Revenue Code, and the percentages that size the installment are set by statute. The point at which the two halves of the sizing test swap places is not published anywhere, because it is a ratio between two of those percentages rather than a figure the statute states. What the September 15 installment has to cover Under 26 U.S.C. 6654(c) there are four required installments for each taxable year, due April 15, June 15 and September 15 of the tax year and January 15 of the year after. The IRS pairs each due date with the stretch of income it covers, an...

Two federal repayment formulas can apply to the same Direct Loan balance in 2026, and they are not built from the same input. The Repayment Assistance Plan (RAP) reads adjusted gross income straight off the return and applies a bracket rate to the whole of it. Income-Based Repayment subtracts 150 percent of the federal poverty guideline first and applies its rate only to what is left. Because one formula starts at the first dollar of income and the other starts after a subtraction, the plan that produces the smaller monthly payment is not the same plan at every income. Worked against the 2026 poverty guideline for a one-person household, the cheaper of the two changes hands six times between $10,000 and $110,000 of adjusted gross income. The Repayment Assistance Plan is the lower payment in three income bands and the higher payment in four. Three of the six switches happen where the two schedules genuinely cross. The other three happen because the Repayment Assistance Plan brackets s...
