No, since you are NOT receiving it as a monthly pension, since you of course are not eligible to draw it out this way at your age, this is not considered receiving a pension. This is drawing it out in a lump sum, which is NOT reportable income for unemployment purposes. Unemployment beneifts are not based on your income. You could come into any amount of income, find a bag of cash, inherit big, win the lottery, and still qualify for unemployment benefits. Whether it is taxable is not the deciding factor, it is whether it is actual work for wages or a pension that you began receiving in a monthly increment based on your age and eligibility to receive it. Social security
retirement benefits are
not a pension, incidentally, not important to you, but might be important for another questioner to know.
But yeah, calling the unemployment system is the first and most important place to start. And even there, sometimes people get whacked advice from inexperienced workers. Be sure you make a note of the date you called, who you spoke to and what you were told. Looking at random internet web sites is the very worst place to get advice.
If you were to report this money on your weekly certifications for benefits, though, it would do nothing but stop your claim while an investigation was done, and then you'd eventually be told the same thing, that your unemployment benefits are not affected by this taking out of a pension at your age.
