I took out a loan from my 401k in 2025 but I pay back the loan through my paycheck. Will I receive a 1099-R form?

No, you will not receive a Form 1099-R for the 401(k) loan, it is not reported on a tax return.

[Opus 17]

As long as your repayments are in good standing, a loan is not a withdrawal and you will not get a 1099-R.

If you stop making payments (because you default somehow, or you leave the company and don't repay it after leaving) then at that time the outstanding balance will become a withdrawal, with different consequences depending on why you stopped payment.
