What changes on 2026 tax returns

A second wave of the federal law starts on January 1, 2026, and much of it changes what clients should do during the year rather than at filing time. Use this list for projections, withholding reviews and year-end meetings, while the 2026 drafts are still being finalised.

Where 2026 work happens during the year

Unlike 2025, the 2026 changes reward clients who act before December. Withholding, plan contributions and the timing of charitable gifts can all be adjusted while the year is open.

  • Re-run 2026 estimates for clients whose 2025 refund was driven by a one-off item.
  • Ask employers whether payroll can separate tips and overtime from the first pay run of 2026.
  • Flag clients who take the standard deduction and give to charity in cash.
  • Check marketplace health coverage clients against their projected income, since excess advance credit is now repaid in full.

Treat drafts as drafts

Several 2026 forms on these pages are IRS drafts. Line numbers and wording can move before the final release, so link client letters to the topic rather than to a line number.

FAQ

Frequently asked questions

Are the 2026 figures final?
The inflation-adjusted amounts come from Rev. Proc. 2025-32 and IRS news releases, which are final. Form layouts marked as drafts can still change, and each form page says when it is quoting a draft.
When do 2026 returns get filed?
Individual returns for tax year 2026 are filed in 2027. The year-end information returns that use the new $2,000 threshold are also due in early 2027.
