Common mistakes to avoid while filling out Form W-9

Mistakes are something we all make. However, mistakes on your tax returns can prove to be costly. Many have found this out the hard way — even a small typo in any of the fields could cost you big. We have prepared a list of common mistakes to avoid while you are filling out your Form W-9.

- Mistyping your name or DBA on the W-9 can actually trigger an audit since it would appear to IRS that you didn't report your form 1099-MISC when you submit your tax return later.

- Same thing may happen if you make a typo in the SSN or EIN. Remember, your customer has no way to verify that you've entered the correct details on your W-9 form.

- Make sure your mailing address is correct, otherwise you will not receive your 1099-MISC form later.

Keep all the forms in one place, for example in PDF Expert on your iPad. This enables a quick access whenever you need them. Once again, make sure you provide accurate information on your W-9. This will ensure that payments you receive are properly reported to the IRS. If you are unsure of some items, always consult with your financial adviser.
