If your pay stub doesn't show any withheld taxes, or if you're not sure, I would strongly suggest that you ask your employer if taxes are being withheld from your pay.
If your employer is NOT withholding taxes, that would mean that he's treating you as an independent contractor and not an employee. If that's the case, you'll need to be paying estimated taxes.
