Virginia is a state that does allow lump sum alimony payments.
If You Receive a Lump Sum Payment
If you accept a lump sum alimony payment, you may face tax consequences. For example, if you receive a lump sum payment that's referred to as "alimony" in your divorce decree, you may be subject to taxes on the full amount for that year. But if the same payment is called a "settlement," you may not be taxed. Don't sign any documents or agree to any terms until you've consulted an expert, such as an accountant who specializes in divorce issues. The money you spend on a consultation could be peanuts compared to what you might owe in income taxes.
