How long should I keep tax returns? In most cases, you should plan on keeping tax returns along with any supporting documents for a period of at least three years following the date you filed or the due date of your tax return, whichever is later. If, for example, you find that you failed to claim a credit on an old return that would've given you a refund, you can amend that return using Form 1040X within three years of its original filing date, or within two years of the date you paid taxes for that return -- whichever is later. Holding on to your old tax records can also work out in your favor. Just as the IRS gets three years to re-examine old tax returns, so, too, can individual tax filers claim refunds up to three years after the fact. How Long Should I Keep My Tax Returns? Don't be too quick to toss out your old tax returns. You should hang onto those forms for a minimum of three years -- sometimes more. That said, the IRS will advise you to keep your old tax returns and records even longer in the following situations: You failed to report income for a given year, and that amount exceeds 25% of the gross income shown on your return. You filed a fraudulent return. You didn't file a return for a given tax year. That said, the IRS will advise you to keep your old tax returns and records even longer in the following situations: 1 You failed to report income for a given year, and that amount exceeds 25% of the gross income shown on your return. 2 You filed a fraudulent return. 3 You didn't file a return for a given tax year. Tax returns sent on or before the deadline. You should keep your records for at least 22 months after the end of the tax year the tax return is for. If you send your 2015 to 2016 tax return online by 31 January 2017, keep your records until at least the end of January 2018. It's natural to want to clear out your filing cabinets and free up more space, but when it comes to tax returns, you shouldn't be too quick to toss out old information. The IRS gets three years from each year's tax filing deadline to audit and reassess old returns. Editor's Note: If your tax return is still buried under a pile of papers next to your computer, it's probably time to do a little organizing. To help get you set we asked Anna Sandall of the Tax Institute the best practices involved in keeping tax records including how long you should hold onto those past returns. So for example, if you filed your 2015 tax return on February 1, 2016, you should have kept the return and supporting documents until at least April 15, 2017. What tax records should I keep? You should keep every tax return and supporting forms. This includes W-2s, 1099s, expense tracking, mileage logs if you itemize and other documents. So why is keeping tax returns for three years important? Keeping tax returns for the three-year time period is tied to the IRS statute of limitations. Query: how long do i keep my tax return?

CT Scan Frequently Asked Questions What is a CT scan? A CT scan also called Computerized Tomography or just CTis an X-ray technique that produces images of your body that visualize internal structures in cross section rather than the overlapping images typically produced by conventional X-ray exams. CT scans use an X-ray unit that rotates around your body and a powerful computer. The result with CT scans is a set of cross-sectional images, like slices, of the inside of your body. Should I do anything special to prepare for a CT scan? How you prepare for a CT scan depends on which part of your body is being scanned. You may be asked to remove your clothing and wear a hospital gown. You'll need to remove any metal objects, such as jewelry, that might interfere with image results. Q&A: About Your CT Scan What is a CT scan? CT, which stands for Computed Tomography (sometimes referred to as a "CAT" scan), is a fast, painless diagnostic tool doctors can use to see inside the body. Physicians use the information they get from a CT scan to rule out or confirm the presence of certain abnormalities or diseases. A CT scan has many uses, but is particularly well-suited to quickly examine people who may have internal injuries from car accidents or other types of trauma. A CT scan can be used to visualize nearly all parts of the body and is used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment. CT of the head is an X-ray-based procedure in which images (pictures) are taken of the entire brain. CT scans of the head/brain can provide more detailed information about brain tissue and brain structures than standard X-rays of the head. Therefore, this can provide more information related to injuries and brain disease. You might have an injection of contrast medium (a type of dye) through a small thin tube (cannula) in your arm. 1 This can: 2 make you feel hot and flushed for a minute or two. 3 give you a metallic taste in your mouth. 4 make you feel like you're passing urine but you aren't this feeling is common and passes quickly. How long does it take? A CT scan can take anywhere from 10 to 30 minutes, depending on what part of the body is being scanned. It also depends on how much of your body the doctors want to look at and whether contrast dye is used. It often takes more time to get you into position and give the contrast dye than to take the pictures. For some types of CT scan, a 'contrast agent' is used to make certain parts of the patient more visible to x-rays. The contrast agent is in the form of a liquid that is injected into the patient prior to scanning. This liquid has iodine in it, and shows up well in CT scans. At our hospital, it'd be very unusual for a CT scan to take more than an hour or two to be read, most are done within 30 minutes. From there, the question is how long does it take for the report to get to the ordering doctor? What will I feel during the scan? CT scanning causes no pain, just as a routine X-ray is painless. If intravenous contrast is used, you may feel warm and flush and get a metallic taste in your mouth. These sensations normally disappear after a few minutes. How long will the scan take? The time required will depend upon the type of scan. If oral contrast is required, about 45 to 60 minutes is needed for the contrast to move through your digestive tract. Actual scan times vary from a few seconds to several minutes. If no oral contrast is required, the examination will take about 15 to 30 minutes, including the time for intravenous preparation and interview. In some cases additional scanning is required as scans are tailored to suit individual diagnostic needs. I do think a lot of hospitals are concerned with customer satisfaction so I think elevating your displeasure with the scan results policy may go a long way. Most hospitals have surveys or complaint forms and if neither of those apply a letter to the Hospital administration may be order. Query: how long does it take for a ct scan?
