It’s tax time…and if you tackle it yourself every year, be sure to check and recheck for errors.  Every tax deduction or tax credit that you miss means more money out of your pocket and into Uncle Sam’s. But there are also simple mistakes that can cause more delays than incorrect deductions.  Forgetting to sign and date the return…yes, this seems like it would be a no-brainer. Yet, year after year, the IRS reports failing to sign your tax return as a top filing mistake. Also, entering the wrong social security number…it can happen to the best of us.  Double check the numbers to make sure they’re correct — and not just yours. Check the Social Security number (or tax ID number) of your spouse, your dependents, any household employees — and your child-care provider, if you are claiming a child-care dependent credit.
