In a few short weeks, whether you like it or not, your taxes are due.

There’s no reason tax time has to be a stressful flurry of last-minute preparations capped off with a sprint to the post office (or accountant). If you take a few little steps each week, you’ll be pleasantly surprised at how much easier it all comes together April 15.

But, unless you’re the financial type, you might not be sure how to break down such a daunting task. That is why we’ve put together this tax-prep schedule. The average “appointment” on this list should take you no more than an hour to complete – and many might take less than five minutes. Make it through this tax-season gauntlet mistake-free and with sanity intact!

A few things to get started with:

•If you have not already, book time with your accountant and buy a tax organizer. If you are going to work with an accountant to prepare your taxes, and you haven’t yet met with him this year, call him today and make an appointment to meet and review your return within three weeks.

•Buy an accordion file, like the Tax.filer from Buttoned Up (www.getbuttonedup.com/our-products/filing-systems/tax-filer), or a plain one with at least 10 pockets from an office supply store.

•Locate last year’s return. The best place to start your tax-prep work is with last year’s return. Why? Because it will serve as an aid for this year’s return. Everything you put on last year’s return you are likely to need again this year. So, make a list of all income sources and every itemized deduction to serve as your master checklist for 2009 returns. It will also tell you if you have a carry-forward or how you treated certain income before. After you find it, make a copy of it and put it in your accordion file in a pocket marked “2008 Return.”

•Gather Social Security information. You will need this for any dependents claimed on your return, and your spouse if you are filing jointly. Gather that information now and put it in a folder named “Dependents.”

•Gather your W-2s and work-related 1099s. Most employers will have sent employees W-2 forms, and independent contractors 1099 forms, by the end of January. These documents detail the amount of money you earned during the previous year and the amount of taxes withheld. Review all documents you have received to be sure that they are accurate, total the income earned and taxes withheld on a separate piece of paper, and then put that along with the forms in your file under a tab named “Income from Work.” If you are missing a form, contact your employer now to get your copy.

This schedule will keep you on track:

March 9

Gather forms for investment income and interest earned.

Investment firms will send out a 1099-B form to you, typically by the middle of February, detailing stock and bond trades you made throughout the 2009 tax year. For each security sold, look up its cost basis and note whether you held that stock for more or less than a year. Then calculate your total capital gains tax liability using a calculator like this one: www.moneychimp.com/features/capgain.htm. Also gather any K-1 forms from partnerships, statements from banks/brokerage firms detailing interest income earned and records of rental income or other supplemental income. Tally the net supplemental income earned on a separate sheet of paper and put it with the tax documents in a folder titled “Capital Gains.”

March 11

If you sold your house this year, gather proof of deductible home improvement expenses.

As long as you have proof that you incurred home-improvement expenses, you can deduct them from the original basis of your home when determining the taxable capital gain. Check with the IRS or an accountant if you are unsure which expenses are deductible. Put the net income earned from the sale of your home along with all relevant documentation in the folder named “Capital Gains.”

March 14

Gather 1098 forms for deductible mortgage interest.

Your mortgage company will provide you with a 1098 form detailing the interest you’ve paid on your loan throughout the year. Highlight the total interest amount paid and double-check that against your mortgage statements for accuracy. Then file the 1098 form in a pocket titled “Deductions.”

March 16

Set aside proof of IRA contributions and check deduction allowances.

For tax year 2009, individuals under age 50 were allowed to contribute $5,000 to their IRA accounts, and those over 60 were allowed to contribute $6,000. Gather either canceled checks or account statements as proof of your contribution. Then check www.irs.gov/publications/p590/ar01.htmlen–US–publink1000230270 for information on how much you can deduct. Make a note of it and keep it with your proof of contribution. Put both the proof of contributions and the amount you can deduct in a folder named “Deductions.”

March 18

Gather relevant work-related receipts.

If you spent money on anything related to work, like a uniform or a computer, but were not reimbursed by your employer for the expense, it is deductible. If you are self-employed, many of the things you use to conduct or promote your business are deductible, such as: computers, phones, utilities and office supplies. Gather all relevant receipts. If you are unsure whether an item is deductible, set it aside in a pile with a question mark. Total the amount spent on items you are sure you can deduct, note that on a piece of paper (or spreadsheet that you print out), paper-clip it to the set of receipts associated with those items, and put into the folder marked “Deductions.”

March 21

Gather records for charitable deductions.

You can take deductions for money and goods donated to charities. However, you must include the receipts detailing the amount of money and/or items you donated with your tax return. Check with the IRS to see what documentation is deemed necessary for monetary and physical goods and gather those today, along with any pictures you might have that substantiate the value of physical items given. Place them in the “Deductions” folder. If you realize that you forgot to get a receipt for a particular donation, contact the organization to get the necessary paperwork.

March 22

Gather proofs of purchase of energy-efficient goods.

The federal government – including the IRS – wants to promote energy-efficient consumption. If you purchased energy-efficient vehicles or items that make your home more efficient, such as solar-energy systems, insulation, hot water heaters, boilers or thermostats, you may qualify for tax credits. Gather your proofs of purchase and put them in a folder marked “Energy Star.”

March 24

Gather receipts for medical co-payments.

While the cost of insurance deducted from your paycheck is generally not deductible, any doctor or hospital bill that you paid throughout the year is deductible and should be itemized on your return. Gather all receipts, add them up, note the total on a separate slip of paper and file in the pocket marked “Deductions.”

March 28

Draft your returns.

Now that you have gathered relevant documentation, actually filling out the tax forms should be more straightforward. Print out a set of federal, state and local forms, grab a pencil and do a “rough draft” tax return. Don’t worry about obsessively double-checking. Just fill out what you can, highlighting areas in which you have questions.

Week of March 29

Meet with your accountant.

Review the draft returns that you have prepared and show the relevant documentation. Ask questions. Get direction on how to revise, or hand the returns to the accountant to finalize.

April 4

Proof your return.

Nobody but you is responsible for signing off on the final document. Go back through your drafts and double-check all of the figures. The most common mistake the IRS finds is miscalculated totals. Be sure to correct any mistakes.

April 8

Fill in your final return and send.

Put all backup documentation back in the accordion folder, label the outside of the folder “2009 Tax Year,” and put away in a safe place. You will need to hold onto it for seven years in case you are audited. As an alternative to snail mail, consider filing electronically, as you will get your return much more quickly.

In the months ahead, use a second accordion file to keep the receipts for the 2010 tax year organized from the start.
