Real example. Real money.

Sarah earns $85,000 with $9,200 in overtime. Under the old rules she paid federal tax on all of it. The 2026 OBBBA law exempts that overtime. TaxCheck caught it in 40 seconds. She updated her W-4 the same afternoon. Her next paycheck was $287 higher.

That's $7,462 per year she almost gave away.

What most people miss

The IRS won't tell you that you're paying too much.

New 2026 rules let you exempt up to $12,500 in overtime pay. Most employers haven't updated your withholding.

If you earn tips, up to $25,000 could now be tax free. Your W-4 still reflects the old law.

Seniors over 65 just got a $6,000 bonus deduction. Nobody sends you a letter about it.

Filing jointly might be costing you thousands more than filing separately. Or the other way around.
