Crossing a state line into or out of Oklahoma

Oklahoma taxes its residents on income earned anywhere, and taxes non-residents on work done inside it. Which return you file depends on which direction you commute.

Oklahoma borders 6 states. They fall into 2 different situations, and which one applies decides whether you file one return or two.

Where you file a nonresident return and claim a credit

Oklahoma has no agreement with Arkansas, Colorado, Kansas, Missouri and New Mexico. Work in one of these and you file a nonresident return there, report the same income again to Oklahoma, and claim a credit for what you already paid. The credit is capped at your Oklahoma liability, so you are not taxed twice, the combined bill lands at roughly the higher of the two rates. On $70,000, Kansas costs the most at $3,600 and Arkansas the least at $3,115, $485 between them.

Work state	Its tax	Oklahoma after credit	Total	Rate that governs
Arkansas	$2,653	$463	$3,115	Oklahoma
Colorado	$2,800	$315	$3,115	Oklahoma
Kansas	$3,600	$0	$3,600	Kansas
Missouri	$3,190	$0	$3,190	Missouri
New Mexico	$3,140	$0	$3,140	New Mexico

Where the work state takes nothing

Texas levies no personal income tax, so there is no return to file there and no credit to claim. But Oklahoma still taxes the wages as a resident. The catch is withholding: an employer in Texas has no state income tax to withhold, so nothing is taken out for Oklahoma either. The liability is real and nothing is being set aside against it, which usually means Oklahoma estimated payments.

What Oklahoma itself takes across a salary range

A single filer, taking the standard deduction. This is the figure every arrangement above is measured against, the tax Oklahoma charges a resident, whether the work happened inside the state or over a line:

Wages	Oklahoma tax	Effective rate
$45,000	$1,990	4.42%
$70,000	$3,115	4.45%
$120,000	$5,365	4.47%

Coming the other way: living in a no-income-tax state, working in Oklahoma

Texas border Oklahoma and levy no personal income tax of their own. A resident of Texas who works in Oklahoma has the simplest arrangement on this page and the least room to improve it: Oklahoma taxes the wages earned inside it, $3,115 on $70,000, there is no home-state return, and so there is nothing to claim a credit against. Living across a border that charges nothing does not reduce the Oklahoma bill by a cent.

Reciprocity cannot help either, even where Oklahoma has agreements: reciprocity shifts the income to the home state's return, and a state with no income tax has no return to shift it to.

What Oklahoma charges as your home state

Oklahoma taxes income on 3 graduated brackets for 2026, from 2.5% up to 4.5%. Because wages stacks on top of any other income, a second source can push part of it into the next bracket.

On the 2026 rate itself: simplified to 3 brackets in 2026, top rate reduced from 4.75% to 4.5%.

State income tax on wages only, 2026 rates. Not tax advice, what this does and doesn't cover.
